When life gives you lemons, make lemonade, yes, and drink all of them. Then you're ready for an adventure. Researchers from the University of Sussex in England say they have found for the first time experimental evidence that sour tastes lead to more risk-taking behaviour in a paper published on 7 June, 2019. In the study, 168 volunteers from the UK and Vietnam were given a 20ml solution representing one of the five main taste groups: bitter, salty, sour, sweet and umami. The tasters then took part in a computerized test that measures risk-taking: they got paid to blow up a digital balloon. The more air in the balloon, the more money they could get; they could cash out whenever they wanted. But if the balloon popped or exploded? Bye bye , potential winnings. When the researchers studied the performance of the volunteers, they found the people who'd tasted sour were much more likely to keep pumping up the balloon compared with people who'd gotten a taste of the other solutions. On average, sour tasters were 39% more likely to push the balloon to its limits than sweet tasters, 20.50% more than bitter, 16.03% more than salty and 40.29% more than umami. This finding makes a degree of sense—without taking risks, we don't learn anything new. And it is obvious that people with disorders such as anxiety and depression are unwilling to take risks. So, the researchers argue, if you have these disorders, maybe adding more sour foods into your diet could help keep that aversion in check. Then you'd be more likely to take chances, like talking to a stranger, and that will lead to self-improvement. 1.Where does this passage most probably come from? A.A travel guide. B.A novel. C.A magazine. D.A poster. 2.What can we learn about the volunteers? A.They came from the University of Sussex in England. B.They got one taste drink after they filled up a balloon.

In 2009, I rescued a skittish donkey. Bo came from a nearby cattle ranch and now lives peacefully on my ranch in the Bitterroot Valley of Montana. But the key to Bo's successful recovery from nervous rescue to happy ranch animal wasn't anything I did. It was my grandson, Dylan. Dylan came with his parents to spend some days with me on their way to Canada for a vacation. Bo kept his distance from the grown-ups, but he showed an unusual fascination with Dylan. So we decided to introduce them. “Move slowly, be quiet, and stoop down sometimes,” I told my grandson. Dylan carefully approached Bo, step by step, holding a soft rubber currycomb. Bo held his ground, but he seemed interested by this little visitor. Dylan rubbed Bo's shoulders and neck with the comb, softly and gently. It's hard for an almost four-year-old to stay still for long. Dylan made one quick move, and Bo was terrified running off. But Bo and Dylan were not ready to give up. Dylan approached again. It was amazing to witness a preschooler learn to control himself in such a short time. As we watched, true love developed between this once distrustful donkey and a gentle boy. Over the next few days, Dylan felt free to sit at Bo's feet while Bo carefully nibbled his shirt collar and hair and rubbed Dylan's back with his bristly chin. Just as Dylan had earned Bo's trust, Bo came up to and hugged him --- yes, a donkey can hug — without knocking him off balance. They met again one week later as the family passed through on their return trip. It was almost dark, but Dylan and his dad travelled far to reach the ranch. Bo came to meet them cheerfully. He is now a changed and trusting donkey. 1.What can we learn about Bo according to paragraph 1? A.He lived peacefully on a cattle ranch. B.He was rescued from the ranch by Dylan. C.He was from Bitterroot Valley of Montana. D.He no longer suffers from nervousness. 2.What does the underlined word “fascination” in the second paragraph probably mean? A.Amusement. B.Interest. C.Patience. D.Respect. 3.What happened after Bo was introduced to Dylan? A.They became friends immediately. B.They were afraid of each other. C.Dylan's sudden move frightened Bo. D.Bo refused the combing from Dylan. 4.What can we infer from the story? A.Dylan and Bo meet once a week. B.Dylan will stay on the ranch for Bo. C.Dylan was knocked down by Bo. D.Dylan's gentleness has changed Bo.
Some libraries use specially-designed buildings to encourage visitors to explore the shelves and settle down with a new book, or use movable libraries to bring books to hard-to-reach populations. No matter how they achieve it, these novel libraries are keeping the magic of reading alive. The Camel Library Service To improve education in the desert of Kenya, the government created a travelling library made up of nine camels bringing books to villages. The library travels four days a week serving the region's nomadic （游牧的）people. Currently the service focuses on children, but with more funding they plan to increase their reach both in distance and the titles they carry. Beach Library Reading a book on the beach is a classic, and in Bulgaria, one library encourages tourists to do just that. The white, weather-resistant shelves lined up not far from the waves feature 6,000 books in 15 languages, so every visitor can find the perfect beach read to enjoy while sunbathing. Macquarie University Library Being environmentally friendly and technologically advanced, this building in Australia was made from recycled materials, features a green roof and was modelled after the look of a tree. It is also state-of -the-art, using robots to bring requested books to the front desk. Seikei University Library Libraries are usually known for their quiet atmosphere, but this one encourages conversation. Hayao designed the library in Japan with rooms preventing all sound from getting in and out. In this way, it shows respect for those who need undisturbed study, while also supporting other methods of learning; the rooms are perfect for study groups and lively discussions. 1.What is special about the Camel Library Service? A.The library serves camels. B.The library is not a fixed one. C.It improves tourism in deserts. D.It combines education with travelling. 2.The tree-like library may probably attract those who . A.prefer sunshine B.want to be models C.are friendly D.care about nature 3.Which library welcomes group discussion? A.Beach Library. B.The Camel Library Service. C.Seikei University Library. D.Macquarie University Library.

We are in a fast-paced, technologically evolving society and we are addicted to social media. In fact, we long for social media. So how does one ensure a positive online reputation (名声)? It’s simple. 1. Be entirely sure about what you’re posting. Party photos with alcohol are an absolute no-no. Would you want to have your boss see these photos? Make sure to post contents that you feel positively reflect you, your creativity and your skills. 2. You have a private Twitter account so you can post anything you want? This is decidedly not the case. Privacy setting make it harder to see your full account, but it’s not impossible. Under no circumstances should you rely on privacy setting as a way to protect inappropriate contents. 3. Keep it classy (优等的)! Discover your brand, or what you want people to think of you. Proper spelling and grammar is always a plus, but it may not be your brand. Think about what you want people to think of you and go with it. Follow these simple rules and you’re on your way to building, or restoring an online reputation. Using social media positively doesn’t mean you can’t have fun and use it to express yourself; however, you want to ensure that you’re OK with anyone seeing everything you post. Once you click post, there’s no looking back. Like it or not, your social networks reflect you—make sure you look like the shining star that you truly are. A.Keep it clean B.Social media is common now C.Don’t trust privacy settings D.Ensure you’re professional
What are you going to do if you are in a burning house? How will you escape? Do you know how to save yourself? Please read the following passage. Escaping a fire is a serious matter. Knowing what to do during a fire can save your life. It is important to know the ways you can use and show them to everyone in the family, such as stairways and fire escapes, but not lifts. From the lower floors of the buildings, escaping through windows is possible. Learn the best way of leaving by windows with the least chance of serious injury. The second floor window is usually not very high from the ground. An average (平均高度的) person, hanging by the finger-tips will have a drop of about six feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way than to stay in a burning building. Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may leak (渗) into the room. On a second or third floor, the best windows for escape are those that open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement (水泥) might end in injury. Bushes (灌木丛) and grass can help to break a fall. 1.It is important to __________. A.put out the fire in the burning house B.know the ways to escape a fire C.jump off a burning house D.keep the door closed 2.Under what condidition may people escape through the window?

Are you an angry bird? When you’re angry, your body becomes tense. 1. Here are some other simple tricks to chill and think before you act. Understand your anger Think like a detective and track down clues about the kinds of situations, people, and events that set off your anger. 2. Even if you can’t get away from them, at least you’ll have more time to prepare for them so they don’t affect you so negatively. You can also think of the situation as an opportunity to practice not getting mad. Go for a walk When you get really angry, walk away from the source. A 5-minute walk outside or another calming activity like yoga are both great strategies for dealing with anger. If your anger arises from the traffic jam you’re stuck in, turn up the radio and sing at the top of your lungs. 3. Write letters 4. So if you’re trying to calm down fast, grab your journal and write it all out. You can simply write your own feelings or try writing a letter to the person who upsets you. You never have to send it and just writing it will help you feel better. Talk about your anger It’s not just writing that helps relieve anger. 5. The trick is not to unload your anger on the person making you upset but to release your pressure by talking with a neutral (中立的) friend, family member, or specialist. A neutral observer can bring reasonable judgment to the situation. You can even try talking out loud to yourself about it. Now that you’ve learned how to keep your anger in check, try some of these little changes that will make you a happier person. A.Expressing it orally can also be incredibly calming. B.Once you’re aware of them, try to avoid them if possible. C.Writing out your feelings really does help you feel better. D.The idea is to create a mental or physical escape from the situation. E.Losing your temper makes you look like the bad guy to everyone else. F.Deep breathing is just one of the ways you can instantly turn a bad mood around. G.Exercise can help people lower their levels of anger and other negative emotions.
Nowadays medical technology seems to be advanced enough for doctors to perform brain transplants (移植). Though this procedure has only been successfully performed on animals so far, doctors are still hoping to perform this procedure on humans. However, in my opinion, brain transplants should not be performed at all, especially not on humans because of the large number of problems and side effects that could come along with. Hopefully these dangerous side effects will convince doctors not to perform this procedure on humans. Despite many benefits technology brings, I do not think this medical technology of brain transplants will help. We were all born with one brain and through childhood to adolescence our mind developed into who we are, so if with a different brain we would no longer be unique. A person with a different brain would seem to be a total stranger and in many ways they would be. No one should steal our identity from us, even if we are seriously injured, and change it to a completely new one. Also for the people who have died with healthy brains, that was their identity and it should not be given to anyone else. Another problem with brain transplants is how doctors can choose what are “healthy” or “normal” brains. An elderly person who has died would have an aged brain that would not be as efficient as a younger person’s brain. Then would doctors have to find healthy brains of the same age as the person who needs it? This could also bring up other factors such as intelligence, gender, or physical problems that a person might have had before death. Also another problem might be how long a brain can be kept “alive” after death and how it can be kept “alive” without damage. Overall, my feelings about this surgery are that it should not be done on humans until doctors have overcome all the problems and obstacles (障碍) that stand in their way of making human brain transplants successful. 1.Why does the author think brain transplants should not be performed at all? A.The cost of the surgery is extremely high. B.Doctors are not able to perform brain transplants. C.A good many problems and side effects may arise. D.This procedure has only been successful on animals. 2.What is the second paragraph mainly about? A.People shouldn’t give their healthy brains to others. B.Having a brain transplant means losing one’s identity. C.Transplanting brains is changing old brains into new ones. D.Having brain transplants indicates stealing identity from others. 3.What do we know about “healthy” brains? A.Aged brains aren’t healthy brains. B.Young brains are always healthy. C.Healthy brains cannot be kept “alive”. D.It’s very difficult to tell healthy brains. 4.What is the author’s purpose in writing the passage? A.To encourage brain donation. B.To stress the importance of brain operation. C.To argue against brain transplants on humans. D.To introduce the technology of brain transplants.
When life gives you pineapples—and hundreds of millions of tons of pineapple waste—what do you do? Engineers in Singapore and Vietnam decided to tum all the waste into something useful—the heat barrier for their pineapple juice. Not only does their new material keep drinks cool better than many commercial coolers, but it could also offer a final resting place for the world’s pineapple waste. To find a use for those leftovers, the researchers mixed pineapple fibers, which they cut up in an electric device, with a sticky agent as a solvent. They then treated the mix with sound waves at frequencies greater than 20 kHz and heated it in an oven at 80℃ for 2 hours. The suspension that formed was then cooled before being freeze-dried. The result was a pale yellow aerogel (气凝胶) that is lightweight, flexible, and more than 96% porous (多孔的)—qualities that make it an ideal material against both heat and sound. When the researchers wrapped a sheet of the pineapple aerogel around a military-style canteen bottle, they found that the aerogel could provide three times the heat exchange reduction of commercially available alternatives—they reported this month in Materials Chemistry and Physics. The gel-wrapped bottle kept -3℃ water cooled below 0℃ for 6 hours and liquid heated to 90℃ above 40℃ for 2.5 hours. What’s more, the pineapple gel also acted as a sound barrier; in another test, the gel did a better job of preventing noise from getting in or out than Basmel, a popular kind of sound barrier. The findings provide a new, eco-friendly approach to recycling agricultural cast-offs—and a good excuse to get a better electric device for your kitchen. 1.Why do engineers come up with the idea of the heat barrier? A.To lower the cost of heat barriers. B.To make good use of pineapple waste. C.To find a better cooler for pineapple juice. D.To turn pineapples into something more useful. 2.What is the last step of making the pineapple aerogel? A.Freeze-drying the suspension. B.Cooling the formed suspension. C.Cutting up the pineapple leftovers. D.Treating the mix with sound waves. 3.What can we learn about the pineapple aerogel from paragraph 4? A.It kept the liquid heated to 130℃ for about 2.5 hours. B.It kept the water cooled below -3℃ for nearly 6 hours. C.It could be three times as effective as other heat barriers. D.It did a better job as a sound barrier than as a heat barrier. 4.What is the best title for the text? A.A Better Way to Keep Drinks Cool. B.An Alternative Way to Recycle Waste. C.Pineapple Waste, a Wonderful Drink Cooler. D.Pineapples, One of the Most Common Fruits.
As temperatures approached 90 degrees in New York City last July 4th, three police officers hurried into a Whole Foods Market to get something cold to drink. What they walked into was a heated human drama. Once inside, the cops (警察) , Lt. Louis Sojo and Officers Esanidy Cuevas and Michael Rivera, were approached by a store security guard who asked for help with a suspected thief. The woman in question didn’t have the look of a career criminal. She was obviously scared, and her cheeks were wet with tears. The cops looked quickly inside her bag. “Al1 we saw was containers of food. We didn’t see anything else,” Cuevas told CBS New York. “I’m hungry,” she explained quietly. Caught red-handed, the woman no doubt expected to be cuffed (带上手铐) and put into prison for the crime of being hungry while poor. But the cops had other ideas. “We’ll pay for her food,” Sojo told the surprised security guard. There’d been no discussion among the three men, no need to see whether they were all in. It went unsaid. Instead, they picked up the woman’s bag and escorted (护送) her to a cash register, where each contrilbuted $10 to pay the bill. She would not be arrested today. All the woman could do was weep in thankfulness. Covering her face with a handkerchief and drying her eyes, she repeated, “Thank you, thank you.” She wasn’t the only one touched by this act of sympathy and understanding. “It was a very beautiful, genuine moment,” says Paul Bozymowski, who was at the store.

Not really. Since having already growing up, we can’t act like little baby and rely on our parents all the time. When I was in Grade Three, my parents asked us to check my homework by myself. I don’t know what to do in that time, so I cried. Before that, I got used to correcting my own homework and became more independent. Check homework by ourselves is very good habit. It can not only help us find mistakes in exams more easy but also let our parents worry less about our studies. Because parents will leave us some day, so we should learn to do everything by ourselves.
