What is mental health? Mental health is an expression we use every day, so it might surprise you that the term ‘mental health’ is frequently misunderstood. 1. According to the WHO, however, mental health is “a state of well-being in which every individual realizes his or her own potential, can deal with the normal stresses of life, can work fruitfully, and is able to make a contribution to her or his community.” 2. To make things a bit clearer, some experts have tried coming up with different terms to explain the difference between ‘mental health’ and ‘mental health conditions’, such as ‘good mental health’, ‘mental well-being’, and even ‘happiness’. 3. As a result, some of them have tried to explain the difference by talking about a continuous whole where mental health is at one end of the range while mental health conditions are at the other. Research shows that high levels of mental health are associated with increased learning, creativity and productivity. 4. In contrast, mental health conditions can cause distress and bad effect on relationships. They are also related to poor physical health and death from suicide. 5. The fact that someone is not experiencing a mental health condition doesn’t necessarily mean his mental health is good. Likewise, it’s possible to be diagnosed with a mental health condition while feeling well in many aspects of life. Briefly, mental health is about being emotionally and socially healthy – the way we think, feel and develop relationships - and not merely the absence of a mental health condition. A. So instead of being about ‘what’s the problem?’, it’s really about ‘what’s going well?'. B. It is often mistakenly used as a substitute (替代) for mental health conditions. C. This, however, will help prevent mental health conditions. D. But others argue that using more words to describe the same thing just adds to the confusion. E. They can also improve social relationships and physical health. F. Many people are affected by depressions, anxiety and suicide. G. But it’s important to remember that mental health is complex.
The Arizona desert is really dry. Anyone stuck in it without water would die from dehydration（脱水）within three days. Unless, that is, they had one of Omar Yaghi’s next-generation water harvesters. Although daytime humidity（湿度）is only about 10 per cent, this rises to 40 per cent at night, which means there’s enough water in the atmosphere to support life — if it can be changed into liquid form. That’s exactly what Yaghi’s device does. It’s a box about the size of a small microwave oven designed to suck the humidity from the air at night and turn it into drinking water the next day using only the heat of the sun as its power source. What makes it work is a powder called a metal-organic framework (MOF), which at normal temperatures attracts water molecules (分子) onto its surface. Warm it up and the water is released, each harvest producing one-third of a cup of pure drinking water. “With further improvements, a device, the size of a washing machine, could produce enough water for the basic needs of a household,” says Yaghi, a chemist at the University of California. One-third of the world’s population lacks safe drinking water; for them such a device could be a lifesaver. But that’s not the limit of the MOF technology. Just as MOFs can help solve the problem of water shortage, they offer a way of reducing a lot of greenhouse gases. In April this year, the carbon dioxide levels in the atmosphere hit an 800,000-year high, contributing to climate change. Recent research suggests ways that MOFs might be able to help mitigate（缓解）this danger to the Earth’s ecosystem. An international team led by chemists from the University of Manchester, UK, reported in 2018 that they had developed an aluminum (Al)-based MOF that can selectively and repeatedly remove another gaseous pollutant, nitrogen dioxide (NO2), from the surrounding atmosphere. This discovery could lead to air-related technologies that seize and change large quantities of other gases, such as carbon dioxide, to reduce air pollution. In 2017, a MOF startup pioneer NuMat Technologies employed MOFs to safely store and deliver dangerous gases. For a given pressure, a tank containing a MOF holds more gas than one without. Or, to put it another way, if a gas tank has a MOF in it, then it does not need to be as highly pressurized in order to hold the same amount of gas, making it safer and less likely to explode, and possible less expensive. Now, about two dozen companies in the past five years are known to be pursuing MOFs, from small startups to larger chemical and automobile companies. And QYResearch forecasts that the MOF market will grow from $70 million in 2017 to $750 million in 2025. “The potential here is just endless,” says Yaghi. “As cheaper materials come into focus, there will continue to be even more opportunities for commercialization.” 1.MOF changes the sucked humidity into water by ________. A. lowering the temperature B. collecting carbon dioxide C. recycling dangerous gases D. absorbing the heat of the sun 2.Aluminum-based MOF can be used to _______. A. reduce greenhouse gases B. produce household water C. deliver dangerous gases D. release water molecules 3.It can be learned that under the same pressure, a tank with a MOF will _______. A. cost more money B. cause more explosions C. hold more gases D. afford more crashes 4.The main purpose of this passage is to ______. A. explain how to use MOF B. describe the future of MOF C. persuade people to buy MOF D. introduce the functions of MOF
For my grandpa Tatay's 90th birthday, our family threw him a surprise — we decorated the backyard with Philippines style and asked guests to wear traditional Filipino costume. While I was jazzed to put on a sarong-like skirt and wrap, my white husband Darren, felt nervous in his barong, a traditional shirt for Filipino man. “I feel like this is cultural appropriation（文化挪用）,” he said, “I honestly feel uncomfortable.” I could understand Darren. Just over this past year, a number of well-known people have gotten into hot water for wearing the dress of other cultures. They had been blamed by the media and the public. But I felt wearing a barong to Tatay’s birthday party was not appropriation. I reassured him that it was just a way to express support and a sense of unity with my Filipino family. And we were wearing these outfits as an act of kindness to Tatay. He is losing his memory, but barong is something that remains in his mind. Still, I wasn't sure whether Darren was appropriating. I turned to an expert for advice. Erich Matthes, a professor of philosophy, told me that there's no clear definition of cultural appropriation, “It's a really messy thing.” “It was OK that Darren wore a barong to your family party, for he's been invited to do so. And it's an act of cultural union,” he says. “But it's not OK if you're wearing the clothing of another culture as part of a cultural exploration or education or to intentionally offend or make fun of the group. If you want to wear a qipao to a party hosted by Chinese friends, but you are not a member of this group, you should ask the most relevant representatives of the culture. Last, be aware that wearing a culture's dress comes with great responsibility.” What the expert suggested hit a big point home for me: What we choose to wear has real power. Seeing Darren in that barong, I knew that he was making an effort to understand and connect with my family. And that, for me, was a beautiful thing. 1.The author asked her husband to wear a barong mainly because it ________. A. makes him look great B. helps show family unity C. keeps a family tradition D. gives her family a surprise 2.The underlined phrase “have gotten into hot water” in Paragraph 3 probably means “________”. A. have gotten into trouble B. have lost their tempers C. have bathed in hot water D. have become more popular 3.According to the article, wearing a culture’s dress probably indicates _____. A. accepting cultural education B. expressing cultural exploration C. supporting cultural appropriation D. shouldering cultural responsibility 4.Which of the following can be the best title for the passage? A. How to Prepare a Birthday Party? B. What to Dress in Different Cultures? C. Wear Clothing of Another Culture? D. Wear Traditional Shirts on Birthday?

One day a woman was walking down the street when she saw a beggar sitting on the corner. As he sat there, passers-by walked by him giving him dirty looks. But when she saw him, the woman was willing to help him. She stopped and looked down, asking him whether he was all right. The man slowly looked up. This was a woman clearly used to the finer things of life. She looked like that she had never missed a meal in her life. His first thought was that she wanted to make fun of him, like so many others had done before. “Leave me alone,” he said angrily. To his surprise, the woman continued standing and smiled. “Are you hungry?” she asked. "No," he answered. "I've just come from dining with the president. Now go away." The woman's smile became even broader. Suddenly the man felt a gentle hand under his arm. "What are you doing, lady?" the man asked angrily. "I said to leave me alone." However, the woman insisted on getting him something to eat in the restaurant across the street. She even asked a passer-by to help grab his other arm and lift him up. Finally, Jack was taken into the restaurant. The woman explained to the manager that she would buy him something to eat. "Not in here!" the manager replied angrily. "Having a person like that here is bad for business." Old Jack smiled. "See, lady. I told you so. Can I leave now?" The woman turned to the manager and smiled. "Sir, are you familiar with E&A, the banking firm down the street?" "Of course I am," the manager answered impatiently. "They hold their weekly meetings in one of my banquet rooms." "And do you make a good profit from that?" "It’s none of your business." "I am Penelope Eddy, CEO of the company." 1.When the beggar first saw the woman, he thought _______. A. she would laugh at him B. she would have meals with him C. she might be fond of him D. she wanted to give him a hand 2.The beggar mentioned his dining with the president to _______.

Several years ago, Masaru Ibuka, chairman of Sony, was at a company planning a meeting. Suddenly he had a brilliant idea. He stopped the meeting and asked everyone present what would happen if Sony removed the recording function and speaker and sold headphones with a tape player instead. Almost everyone thought he was crazy. Still, Ibuka kept thinking about his idea and worked at improving it. The result, of course, turned out to be the wildly successful Sony Walkman. Good ideas often start with a seemingly silly question. Bill Bowerman was making breakfast one day. As he stood there making waffles (华夫饼干)for his son, he wondered what would happen if he poured rubber into his waffle iron. Later ,he tried it and the result looked something like the bottom of most sports shoes we see today. Still, when he took this idea to several existing shoe companies, he was laughed at. In fact, every single company turned him down. Though rather discouraged, Bowerman insisted and went on to form his own company, making NIKE athletic shoes. Sometimes good ideas grow out of frustration .When Fred Smith was a student at Yale University, he had some paperwork that he needed to have delivered across the country the next day. Smith was amazed to find out that overnight delivery was impossible. He sat for a long while, lost in thought. Why couldn’t there be a reliable overnight mail delivery service? He decided to design one. Smith did just that and turned his design into a class project. His business professor gave him only a C for his efforts. However, Smith was not through. He improved the idea in that class project and finally turned it into one of the first and most successful overnight mail service in the world — FedEx. We know that each of these ideas led to a very successful product or service that has changed the way many of us live. The best questions are usually open-ended and are often silly, Children aren’t afraid to ask such questions, but adults frequently are. Think how different the world might be if people never asked “ silly” questions! 1.Which of the following is TRUE according to the passage? A. Sony Walkman achieved great success with its recording function and speaker. B. Bill Bowerman was experimenting with rubber for large shoe companies. C. Shoe companies rejected Bill Bowerman as they failed to see the potential of Nike. D. Fred Smith got the idea of an overnight mail service from his own experience. 2.What do the three persons mentioned in the passage have in common? A. They were all determined about carrying out their ideas. B. They were good at answering other people’s silly questions. C. They started their own company after discussing with others. D. They had a very clear plan for their new ideas at the very start. 3.We can conclude from the passage that _______. A. asking others for their silly questions leads to inventions B. lots of creative ideas usually end up as “silly” questions C. adults usually ask more silly questions than children D. crazy ideas sometimes contribute to great inventions 4.The passage is mainly developed by_______. A. analyzing possible reasons B. presenting different opinions C. providing typical examples D. listing practical suggestion
March 21 has been declared World Sleep Day，a time to recognize and celebrate the value of sleep．Many sleep experts hope it will be a wake-up call． According to a 2016 poll（民意调查）by the National Sleep Foundation，nearly 4 in 5 Americans don't get as much sleep as they should during the workweek．On average，adults are thought to need at least eight hours of sleep a night，although some can manage with less and some won't do well without more．But the survey found that，on workdays，only 21% of Americans actually get a full eight hours of sleep，and another 21% get less than six． To many of us，the thought of spending more time sleeping is，well，a big yawn．On the other hand，the thought of being smarter，thinner，healthier and more cheerful has a certain appeal．And those are just a few of the advantages that can be ours if we consistently get enough sleep， researchers say．Also on the plus side： We're likely to have better skin，better memories，better judgment，and，oh，yes，longer lives． "When you lose even one hour of sleep for any reason，it influences your performance the next day，" says Dr．Alon Avidan，director of the UCLA Sleep Disorders Center． A study published last year found the same to be true even of children． When kids aged 8 to 12 slept for just one hour less for four nights，they didn't function as well during the day． But sleeping has an image problem．"We see napping or sleeping as lazy，" says Jennifer Vriend，a clinical psychologist in Ottawa，Canada，and the leading author of the study with children．"We put so much emphasis on diet，nutrition and exercise．Sleep is in the back seat．" In fact，she adds，no matter how much we work out，no matter how well we eat，we can't be in top physical shape unless we also get plenty of sleep． 1.The underlined part in Paragraph 1 means ______ ． A. To wake up the sleepers B. To draw people's attention C. To serve as a morning call D. To declare the special day 2.From Paragraph 3 we can infer that ______ . A. The thought of being healthier is not very attractive B. Sleeping has nothing to do with one's expectations C. Enough sleep is the guarantee of the appealing things D. Spending more time on sleeping is a waste of time 3.What Jennifer Vriend said in the last paragraph implies that ______ ． A. People care little about sleeping B. Sleeping is not important C.

It's that time of year when people need to lock their cars．It's not because there are a lot of criminals running around stealing cars．Rather，it's because of good-hearted neighbors who want to share their harvest．Especially with this year's large crop，leaving a car unlocked in my neighborhood is an invitation for someone to fill it with zucchini（西葫芦）． My sister，Sharon，recently had a good year for tomatoes．She and her family had eaten and canned so many that they had begun to feel their skin turn slightly red．That's when she decided it was time to share her blessings．She started calling everyone she knew．When that failed，she began asking everyone in the neighborhood，eventually finding a neighbor delighted to have the tomatoes．"Feel free to take whatever you want，"Sharon told her．Later that day，Sharon found that her garden had indeed been harvested．She felt happy that she could help someone and that the food didn't go to waste． A few days later，Sharon answered the door．There was the neighbor，holding a hot loaf of bread．The neighbor smiled pleasantly，"I wanted to thank you for all of the tomatoes，and I have to admit that I took a few other things and hoped you wouldn't mind．" Sharon couldn't think of anything else in her garden that had been worth harvesting and said so．"Oh，but you did，"the neighbor said．"You had some of the prettiest zucchini I've ever seen．" Sharon was confused．They hadn't even planted any zucchini．But her neighbor insisted that there really were bright-green zucchini in her garden．Sharon felt curious and decided to go to see where the zucchini had grown．The two of them walked together into the backyard．When the neighbor pointed at the long green vegetables，Sharon smiled．"Well，actually，those are cucumbers（黄瓜）that we never harvested，because they got too big，soft and bitter for eating．" The neighbor looked at Sharon，shock written all over her face．She gulped（哽住）a few times，and then，smiling，held out the bread，part of a batch she had shared all over the neighborhood．"I brought you a nice loaf of cucumber bread．I hope you like it．" 1.Why does the author warn people in the neighborhood to lock their cars？ A.
