Travel Tips for New Zealand If you’re looking for some adventure in one of the amazing countries on Earth, then New Zealand is a must! 1.! But there are a few things you should know before you head over to it. 1. Bring every kind of clothing you own That might be a bit surprising, but we have some crazy weather here. From snow in Southland, to windy Wellington, to Auckland, you may experience four seasons in one day! You’d be forgiven for thinking that you could just bring your hot weather clothes if you’re here in the “summer months”. 2.. 2. New Zealand beaches are amazing, but dangerous New Zealand has some of the most beautiful beaches in the world, and it’s not uncommon to have a whole beach for yourself. Sadly though, I’ve seen countless tourists on the news who have underestimated (低估) our beaches and ended up having to be rescued, or worse. Though a lot of the beaches are popular destinations, make sure you read the signs or ask a local to make sure it’s safe. 3. You’ll soon find out that the sun in New Zealand might not be as hot, but you’ll burn a lot faster than anywhere else. 3. 4. Sure, there are plenty of tours that you can go on to see different parts of the country, but by hiring your own car, you’ll have the freedom of the open road. 5.. So, getting around is much easier with your own car and you’ll be able to come and go as you please. Don’t forget to drive on the LEFT side of the road down here! A. It really is a country like no other B. Also remember to apply sunscreen (防晒霜) C. You will need a car to get around D. You will come back to New Zealand for more E. New Zealand’s public transport is not good enough F. But summer often doesn’t truly kick in until mid-late January, and even then it’s touch-and-go G. If you go for a bush walk in New Zealand, your biggest danger is slipping on some rocks or getting lost
In 2012, an iPhone fell into my hands. This smart technology seemed like the entrance to only fun and positive things like chatting with friends and blogging. However, seven years later, I had become horribly limited to it. Recent reports show that I’m not alone. According to a study, the average American spends five hours a day on smart devices (装置) and about 2.5 of those hours are spent on social, messaging, media and entertainment apps. It’s hard to explain when the love and joy I felt for my iPhone turned into a dependency. I fell asleep to my phone every night and woke to it each morning. I checked the weather app every morning before I chose how to dress for the day. I used it to help me find my way through a city I should know well enough on my own. I updated my email box every time I picked my phone up. Just like with any addiction, my phone dependency began to influence my life. While spending time with family, I’d stare into a small screen on my lap instead of being involved in communicating with my loved ones. At work, my productivity levels dropped. And then, my four-year relationship came to an end. Eventually, I was left with years of memories and a mobile phone that couldn’t provide enjoyable company across a dinner table, share in the joys of experiencing a concert or kiss me goodnight before bed. Now, I move through life with more purpose and intention. I’ve cut back on carelessly giving away my limited time and attention to my phone. Instead, I focus my efforts on being as present as possible. Truly training the mind to stay present is a long and challenging road, but it’s important to start somewhere. I hope you’ll take a deep look at your own phone habits and reevaluate how important a role you are letting it play in your life. Whether or not you’ve reached a place in your life where your screen time feels problematic, there’s no harm in mindfully giving your current practices some thought. 1.What does the author mean by saying “I’m not alone” underlined in Paragraph 2? A.He takes his iPhone for company. B.He has many friends around him. C.There’re many Americans like him. D.Blogging brings him great pleasure. 2.According to Paragraph 3, the author _________. A.was quite confused about some apps B.became hopelessly addicted to his iPhone C.was afraid of spending more time on his iPhone D.never dressed himself by checking the weather app 3.What does Paragraph 4 mainly focus on? A.Why the author’s productivity levels dropped. B.Why the author finally had phone dependency. C.How the author bravely corrected his mistakes. D.How the author’s life was negatively affected. 4.What does the author intend to do in the last paragraph? A.Persuade people to live a no-phone life. B.Advise people to use their phones reasonably. C.Inspire people to consider their roles in life again. D.Urge people to devote their spare time to screens.
In a national survey, just 1 in 3 students thought that smoking on some days, but not others, can cause a lot of harm. This smoking pattern is common. It is also dangerous. In fact, its health risks are about the same as smoking heavily, report Stephen Amrock and Michael Weitzman. Their new study’s findings show that most kids do not see risks in smoking the occasional (偶尔的) cigarette. For their study, Amrock and Weitzman analyzed data from the 2012 National Youth Tobacco Survey. It had probed (探究) tobacco-related knowledge, attitudes and behaviors in 24,658 students. All were in grades 6 through 12 and lived throughout the 50 U. S. states and the district of Columbia. Most teens knew that heavy smoking can be harmful. About 2 in every 3 students recognized that smoking even just a few cigarettes each day can be harmful (有危害的). Only 1 in3 students, however, recognized that occasional—non-daily—smoking is harmful. Among teens who smoke this way—intermittently—just 1 out of every 7 understood their habit was dangerous. Occasional smoking is not safe, so “we really need to have a conversation” with whoever thinks otherwise, notes Dave Dobbins. He heads research and public education at Legacy, a group based in Washington, D. C. It encourages teens to reject tobacco. “Intermittent smoking carries lots of risks,” Dobbins explains. These include the chance that light use will progress to heavier smoking. “We explain to kids that light smoking is smoking,” says Dobbins, who was not connected with the study. And, he adds, his group points out that “the dangers begin right away”. Adults who are light or intermittent smokers are those most willing and able to quit. Amrock and Weitzman note. Most smokers start by age 18. That’s why the NYU School of Medicine researchers suggest anti-smoking efforts should target youth who today are light or occasional smokers. 1.What’s the text mainly about? A.Occasional smoking. B.Health and smoking. C.The number of smokers. D.Anti-smoking efforts. 2.Where can you find the data showing students’ views on different smoking patterns? A.In Paragraph 1. B.In Paragraph 3. C.In Paragraph 2. D.In Paragraph 4. 3.What’s the meaning of the underlined “intermittently” in Paragraph 3? A.Heavily. B.Continuously. C.Occasionally. D.Purposefully. 4.Dave Dobbins agrees that ________. A.dangers of kids’ light smoking appear in no time B.light smoking is sure to result in heavy smoking C.most teens have realized the risks of light smoking D.light smokers are likely to quit smoking naturally
Constantin Levaditi was born in Galati, Romania in 1874. His family was poor and his father was a Greek immigrant who worked in the Galati port and his mother was Romanian. When he was only six years old he had to start working in a shop as both of his parents fell ill. His job was to deliver orders from his uncle’s shop. After two years his parents died and he was taken into care by one of his relatives who worked as a nurse in a hospital. His relative noticed that he was very smart and sent him to school. After graduating from high school, he decided to study at the medical school in Bucharest where he studied under Professor Victor Babes. Levaditi became a doctor in 1902 and then he specialized in researching tuberculosis (结核病) in Paris at the Louis Pasteur Institute and to Frankfurt, at the Experimental Therapy Institute. He also managed to contribute to the invention of the anti-polio vaccine (消除小儿麻痹症的疫苗) in1913. Levaditi returned to Romania in 1919 as a researcher to teach at university but Romanian universities did not accept him as he criticized Romania’s national health system and its political parties. He often said that it was not acceptable that the government did not care for its people and that there were not enough doctors and hospitals. Thus, he returned to France to continue his research in 1920. That same year he was invited to lead the Rockefeller Institute in New York but he refused. In 1926 Levaditi became a member of the Romanian Academy. Later on, he was in charge of the bacteriology (细菌学) French school and he devoted his last years to research on antibiotics (抗生素) and other medicines. 1.What do the first two paragraphs tell us about Levaditi? A.He went to school thanks to his teachers. B.He was born into a wealthy family. C.He lost his parents at an early age. D.He met with Victor Babes at high school. 2.What was one reason why Levaditi returned to France in 1920? A.The conflict between universities and political parties. B.His dissatisfaction with the health system in Romania. C.The invitation of the Rockefeller Institute. D.The lack of doctors and hospitals in France. 3.Which of the following events about Levaditi happened first? A.He did a careful study of tuberculosis in Paris. B.He was in charge of the bacteriology French school. C.He became a member of the Romanian Academy. D.He devoted himself to the invention of anti-polio vaccine. 4.What is the text mainly about?

Fuerteventura, Spain Fuerteventura is a great place awaiting your discovery. Here are some reasons. La Concha beach Located in northeastern Fuerteventura are a number of family-friendly beaches. One of the most popular is La Concha, which is dressed in white sand and beautified with calm water. The beach is close to the town and at sunset, most tourists rush to see the skies turn beautiful colours in just a few short moments. At low tide (潮汐), small pools of water form, and these are great for the little members of the family to take a dive in. There are enough parking lots and plenty of restaurants to choose from. Corralejo Natural Park If you are looking to experience the desert nature of Fuerteventura, Corralejo Natural Park is the place to be. It is a coin with two sides. One is characterized by volcanic scenery, and the other is white sand that has been cleansed by the blue water of the Atlantic Ocean. Getting to the park can be easily done by road, but exploring it demands that you put on your hiking shoes and take a walk through the natural wonderland. Costa Calma Beach Costa Calma Beach is characterized by blue waters and white sand. The beach is not packed, so you will get a chance to be just with your thoughts as you sunbathe on the sand. When the winds are swift, Costa Calma turns into a hot spot for surfers, ideal for those looking to get a surfing course. The road leading to the beach is fenced by green plants meaning the magic starts even before you get there. Cofete Beach It’s hard to find a fitting description for this wild beach. Its shoreline is great for its golden sand and wild water. Getting to Cofete Beach is not easy: perhaps that’s why this place is still in its original state. The road has difficult spots that require expert driving skills. But, if you can tolerate it, you will be treated with some amazing views. 1.Which place is recommended for a family with kids? A.Cofete Beach. B.Corralejo Natural Park. C.Costa Calma Beach. D.La Concha Beach. 2.What can people do at Corralejo Natural Park? A.Learn how to surf. B.Sunbathe on the golden sand.

A couple of weeks ago, when we were leaving one of those horrible giant trampoline bouncy(弹跳床)places, my 11－year－old daughter said to me, “I don't think I'm very athletic, you know, like Rocket (her brother).

How Many Cups of Coffee per Day Are Too Many? From cappuccinos to cold brew, coffee is a must-have to start the day for many people. 1. However, a new study suggests too much coffee can be harmful. This is what a recent study shows. 2. A University of South Australia study led by Elian Hypponen suggests a couple of cups to start your day probably won’t hurt — and may even be good for you. But drinking six or more cups of coffee a day can increase your risk of heart disease by up to 22%, the researchers found. A cup was defined as eight ounces of coffee. Knowing the limits of what's good for us and what's not is necessary. 3. About one in four deaths in the United States is due to heart disease, according to the U.S. Centers for Disease Control and Prevention. Heart disease is the leading cause of death worldwide. That's why Elian set out to discover how much caffeine causes high blood pressure. 4. Elian says her findings suggest that sipping two to three cups per day is pretty safe and possibly beneficial. She also notes that if you're generally healthy, lots of evidence suggests that four cups per day shouldn't be harmful. 5. Even though the research says five cups of coffee is permissible, each person should know his or her own limit. If we begin having difficulty sleeping or feeling nervous, we might have reached our limit for the day. A. Drink no more than six cups per day. B. Over the limits and our health will pay for it. C. Coffee is the most popular drink in the world. D. But of course, don't forget to listen to our body. E. The relation between them is quite complicated. F. As we know, it is a key heart disease risk factor. G. It sets you off on an energetic morning and prepares you for a busy day.
For all the technological wonders of modem medicine, health care-with its fax machines and clipboards(写字板)—is out of date. This outdated era is slowly drawing to a close as the industry catches up with the artificial-intelligence ( AI) revolution. Eric Topol, an expert in heart disease and enthusiast for digital medicine, thinks AI will be particularly useful for such tasks as examining images, observing heart traces for abnormalities or turning doctors' words into patient records. It will be able to use masses of data to work out the best treatments, and improve workflows in hospitals. In short, AI is set to save time, lives and money. The fear some people have is that AI will be used to deepen the assembly-line culture of modem medicine. If it gives a “ gift of time” to doctors, they argue that this bonus should be used to extend consultations, rather than simply speeding through them more efficiently. That is a fine idea, but as health swallows an ever-bigger share of national wealth, greater efficiency is exactly what is needed, at least so far as governments and insurers are concerned. Otherwise, rich societies may fail to cope with the needs of ageing and growing populations. An extra five minutes spent chatting with a patient is costly as well as valuable. The AI revolution will also enable managerial accountants to adjust and evaluate every aspect of treatment. The autonomy of the doctor will surely be weakened, especially, perhaps, in public-health systems which are duty-bound to cut unnecessary costs. The Hippocratic Oath(誓言) holds that there is an art to medicine as well as a science, and that “warmth, sympathy and understanding may outweigh the surgeon's knife or the chemist's drug”. There's lots of sense in it: the patients of sympathetic physicians have been shown to recover better. Yet as the supply of human carers fails to satisfy the demand for health care, the future may involve consultations on smartphones and measurements monitored by chatbots. The considerately warmed stethoscope ( 听诊器) ,placed gently on a patient's back, may become a relic of the past. 1.What's Dr Topol's attitude toward AI's coming into medicine? A.Concerned. B.Doubtful. C.Optimistic. D.Cautious. 2.What does the author of the text attach more importance to? A.Medical costs. B.National wealth. C.Longer consultation. D.Greater efficiency. 3.Why is the Hippocratic Oath mentioned? A.To prove the bright future of AI. B.To show the advantage of a human doctor. C.To explain medical equipment is more important. D.To argue a human doctor performs as well as a robot. 4.What may be the best title for the text? A.Health care and AI B.AI and its applications C.Doctors and Patients D.Dr Topol and digital medicine
New data presented this week at the annual Associated Professional Sleep Societies (APSS) suggest that a student's preferred sleeping schedule has a lot to do with his or her grade-point average in school. In one study, researchers at the University of Pittsburg revealed that poor sleep habits among high schoolers led to lower grades, particularly in math. It's no surprise that poor sleep habits may negatively impact academic performance. And dozens of studies have linked an increase in nightly sleep to better cognition and alertness. The new research, however, goes a step further, quantifying the impact of erratic or inadequate sleep on grades. These findings are more convincing than saying that if you get more sleep, you'll feel better," says Jennifer Cousins, a lead researcher of the study. The study involved data from 56 adolescents (34 female) between the ages of 14 and 18 years. They were asked to fill out sleep diaries for one week and wear a special activity monitor on their wrists, which recorded when the students were asleep or awake. Overall, teens with poor sleep habits received lower grades than students who stuck with a more regular sleep routine. Interestingly, Cousins also found that different sleep habits had different effects on the students' school performance：those who woke up more often during the night did worse in math, for example, while those who slept peacefully through the night tended to get better grades in English. These findings bring up new questions about teasing out（探讨）the details of what is important about sleep that impacts learning," says Cousins. "Does more sleep improve our ability to deal with abstract concepts found in math, or does sleep quality increase creativity? We don't know the answers, and don't want to draw those conclusions yet. But this helps us understand more about how sleep helps the things we do in daily life. " Authors of the study point out that the results provide overwhelming evidence of the importance of sleep during a period of development that is critical for adolescents and recommend sleep education as a prevention tool to help increase awareness of the importance of sleep and of the negative consequences of poor sleep. 1.The underlined word "erratic" in the second paragraph probably means______. A.adequate B.different C.stable D.irregular 2.We can learn from Jennifer Cousins' research that_____. A.lower grades in math are related to more awakenings at night B.the longer you sleep, the better your grades in English will be C.the findings will cause new insoluble problems about sleeping and learning D.different sleep habits have similar effects on students' learning 3.Which of the following do you think Jennifer Cousins will NOT agree with? A.People should understand the importance of sleep for students. B.Whether greater sleep quality help increase students' creativity is not known yet. C.Students' grades mainly depend on their sleep quality. D.The study helps researchers understand how sleep affects learning. 4.Which of the following would be the best title for the passage? A.The More Sleep, the Better Cognition B.The Poorer Sleep Habits, the Lower Grades C.The More Sleep, the Better You Will Feel D.The More Peacefully You Sleep, the Higher Grades You Will Get
When Brody, a 4-year-old Connecticut boy, was asked what wish he wanted to come true, his only dream was that he could be able to play outside. Brody was born premature (早产) at 27 weeks, which caused him to overheat and burn easily. That means he can't spend any time outside and he'll get burn blisters (水疱) on his face even when he is driven to the hospital. Besides, there are a lot of things he can't do. He has trouble walking and only began talking one year ago. Brody can't eat or drink and has to wear a backpack 24/7 that contains a pump that feeds him. “I can't even count the number of surgeries he's had since he was born,” Brody's mother said. “He's spent probably half his life at the hospital.” When Make-A-Wish Connecticut, an organization that creates life-changing wishes for children with critical illnesses, heard about Brody's request to play outside, they immediately jumped into action. “It's the most simple, most sweet wish, just to play outside but it seems to be the most difficult to realize.” said Debbie Artinian, the manager of Make-A-Wish Connecticut. Artinian and her team determined that a temperature-controlled tent outside Brody's home where he could play and not be in the sun would be the best option. But they had to find a tent that could stand weather conditions like wind and snow and had the right material to block all UV rays. Luckily, Artinian found a company based in the United Kingdom that could design and make the tent. Make-A-Wish Connecticut learnt that Brody loves the beach, even though he is not able to go into water because of his backpack. So they filled the tent with water toys and a kids’ pool filled with balls to make Brody feel as much as possible like he's out at the beach. Brody got his first look at the tent earlier this summer. “When he walked out of the door and I saw his face, it was just everything,” said Artinian. “Now when Brody says ‘Can I go out and play?’, his mom can say, “Yes.” “Brody is now enjoying spending nearly all his time "outside” in the tent. It's hard to make life completely normal for Brody, but Artinian and her team tried to make it as normal as they could. 1.What can we learn about Brody? A.He can't be exposed to sunlight.

If you have never been on a cruise （乘船游览）, it can seem like its own world—with its own rules and secret language. So here we are going to lay out the very basics of going on a cruise. Do I need a passport to go on a cruise? You may need a passport, but you should take one anyway. Besides the fact that you are going to need an ID card to board the ship in the first place, a lot of ports require one. How much luggage can I take on board? For the most part, cruise ships aren’t like planes—there isn’t a strictly regulated amount of luggage you can take with you, and you are not going to be charged for bringing too much. Keep in mind that cabin storage space can be tight. Everything, including your empty luggage, is going to have to fit inside and you don’t want to be tripping over it for your whole vacation. Things like guns and knives are banned, but regulations vary from ship to ship about things like irons （generally a no） and hair dryers （generally a yes）. Some ships allow you to bring a bottle of wine, but nearly all ban bringing your own hard alcohol. What’s the process for boarding a cruise ship? Boarding a cruise ship is like boarding a plane—there are regulations or when to arrive, how to check-in, and what security you have to go through. Most cruise lines have transportation available from the airport; otherwise they normally own a paid parking lot where you can leave your car. 1.What will you have to show when you board a ship in the first place? A.A credit card. B.A post card. C.An ID card. D.Luggage. 2.What can you take when you are on a cruise? A.As much alcohol as you can. B.More luggage than on a plane. C.Less luggage than on a plane. D.As many guns and knives as you can. 3.Where does the text probably come from? A.A storybook. B.A guidebook. C.A book review. D.A science report.

短文改错 China and Western country may have different cultural beliefs about certain animals. But when it comes to pigs, we somehow reach an agreement that pigs are lazy, ugly, stupidly and shameless. Neither of these words describing pigs are exactly positive. Moreover, the truth is what pigs have some good qualities. And there’s probably no good time to clear their names than now, with the arrival of the Year of the Pig on Chinese Spring Festival, which fell February 5 this year. According to a paper publishing in 2017, pigs can tell between those who treat them well or those who don’t. Perhaps these are the qualities of pigs to keep it in mind-their intelligence, cuteness and patience.

Public Speaking Public speaking can be defined as the act of making a speech in front of a group of listeners. The types of public speaking are deliberately structured with three general purposes: to inform, to persuade and to entertain. An informative speech has a purpose to inform, or give knowledge to its audience. 1.For persuasive speech, the speaker would try to change the mindset, perception, or behavior of the audience for their own good. Thus, the speaker needs to look for common ground with the audience and try to relate to what they might agree on. The last type is a ceremonial speech. It tends to be less formal and more personal than the other types of speeches. No matter how well you know the person you are giving speech about, try not to say bad things about them, even if it is meant to be a joke. 2.Sparing some time to practice will help build confidence and help determine how long the presentation will last. Aside from it, knowing who the audience will be is quite necessary. Try to get as much information as possible regarding this particular area related to the audience. Knowing the “battlefield” in advance will give the speakers a huge advantage. Language is the main aspect a speaker needs to pay attention to while giving a speech. 3.A speaker needs to choose their words carefully and make it clear to the audience what they mean. Often, when given a speech, the audience look up to the speaker to give them something new and useful. 4.Language and delivery alone will not be sufficient if the speaker does not have the body language. The movement and gesture of a speaker also affect the audience. While closing the speech or presentation, speakers can restate their main points, just to remind the audience of the important things that have been said. 5. A. It needs to be used clearly. B. These speeches mark special occasions. C. The important thing to watch about is not to put in too much information. D. The key of perfecting anything is through practice, including public speaking. E. They can also end it with a special message and encourage the audience to ask questions. F. Knowing how public speaking is done is a key part in understanding the importance of it. G. Thus, the speaker needs to know how to deliver their speech to fulfill the audience‟s expectation.
Food experts say washing could spread the germs on your turkey in the kitchen sink or nearby food. But it's been a challenge trying to convince cooks to stop rinsing （冲洗）off raw poultry. Germs that can make people sick are common in the guts of healthy poultry and are legally allowed to be on raw turkey and chicken. The assumption is that nobody eats their poultry raw, and that thorough cooking will kill the bacteria. The do — not — wash raw poultry advice from the USDA is relatively new and perhaps hasn't caught on because it goes against the common belief that washing makes things clean, said Chapman. Benjamin Chapman, a study author and food safety expert at North Carolina State University, said the instinct to wash raw poultry goes back at least decades when people relied more on visual clues to spot problems with poultry. Meanwhile, washing hands and surfaces are also important. But food preparation is a complicated act, and germs from poultry can be spread even if it's not washed, especially when birds are removed from packaging. The USDA-funded study stresses that point. Researchers sprayed raw chicken with a harmless strain of E. coli （大肠杆菌）and watched volunteer cooks at test kitchens. Among those who washed their raw chicken, about a quarter ended up spreading the bacteria to their lettuce. But even some of those who did not rinse the chicken got germs on the lettuce. And there are other opportunities for germs to survive on turkeys: melting and cooking. To ensure a bird is thoroughly cooked, they say to use a thermometer to check that the deepest and thickest parts of it have reached 165 degrees. Even after the meal is cooked, you aren't out of the danger zone. To keep turkeys and other leftovers safe, experts say they should be refrigerated after two hours. 1.People don't accept USDA's advice because____. A.the advice is relatively new B.cleaning seems more trustworthy C.cooks clean the turkey before cooking it D.heat can kill most germs and no one eats raw food 2.What can be concluded from Paragraph 4? A.Food packages carry germs. B.Hands and surfaces are easy to get E. coli. C.Germs from a turkey can be spread whether it is washed or not. D.Multiple methods should be applied to food to get rid of germs. 3.Which way may help to cook a turkey safely? A.Rinse off the turkey before it is heated. B.Keep the turkey away from the lettuce and refrigerator. C.Wash hands and packages before taking out the turkey. D.Use a thermometer to check the temperature of the turkey. 4.From which section of a magazine is the text probably taken? A.Culture. B.Science. C.Education. D.Medicine.
