AFor the past week since school took a break for summer, our 14-year-old daughter, Alayna, has been hanging out almost daily with a group of friends. They would ride skateboards across town to spend time at our house.A few days ago, we were all sitting around, and I mentioned I used to ride a skateboard when I was growing up. They invited me to skateboard with them. It was about 10 pm, but all of that teenage energy must have been contagious because I was ready to have a try! We all headed out to the sidewalk in front of our house. I was slow and really careful, but I could still ride one. The boys seemed to think it was cool that “Mama Neal” (as they call me) could ride a skateboard.The next morning, Alayna and I were laughing about this whole experience, and I said to her, “If anyone asks you what your mom is doing these days, you can just tell the m, ‘Oh, she’s a skateboarder.’ I started laughing at my own joke. But it was one of those strange moments when you have so much emotion that the laugh comes out and instantly transforms into a hysterical (歇斯底里的) cry. Tears were rolling down my cheeks. My poor daughter didn’t know how to react. It was awkward.I have realized how much of my identity is wrapped up in what I do. Getting dressed to go to work was one of the highlights (最好的部分) of my day. I think most people have imagined what it would be like to walk awayfrom something familiar. I haven’t doubted my decision. I don’t want to prove my worth by what I do. I didn’t know where to begin days ago, but now I’ll just go for a ride on my skateboard. I ju st want to secure just being myself.21. What does the underlined word “contagious” in Paragraph 2 probably mean?A. Very valuable and important.B. Producing new ideas or things.C. Careful to avoid danger or risks.D. Spreading quickly among people.22. What can we learn about the author from Paragraph 3?A. She regretted what she had done the day before.B. She wanted to please her kid by telling jokes.C. She failed to stay in control of her emotions.D. She expressed her love for skateboarding.23. What actually happened to the author?A. She tried to follow a hobby.B. She left her job not long ago.C. She took a wonderful summer holiday.D. She realized she’s a failure as a mother.BShinrin-yoku means “forest bathing”. Forest bathing doesn’t me an you take a bath in the forest; rather, you simply go for a walk in the woods or a city park, where you relax by using all your senses to experience nature. Yoshifumi Miyazaki, from Chiba University, is among a growing number of scientists who have begun studying the science behind the effects of nature on human health. In his book Shinrin-yoku: The Japanese Art of Forest Bathing, Miyazaki explains the techniques of forest bathing.Miyazaki has an interesting theory about why shinrin-yoku is so effective. He points out that for more than 99.99% of the time, humans have lived in a natural environment. In fact, in 1800, only 3% of the world’s population lived in cities, and by 2016, this figure reached 54%. This is only going to get worse; officials predict that by 2050, 66% will live in cities.This suggests we live in our modern society with bodies that are still used to the natural environment, he writes in the book, because “genes cannot change over just a few hundred years”. The science behind the research studies he presents in the book makes a compelling (引人注目的) case that forest bathing is an effective method for reducing stress in today’s world.Now city planners are becoming increasingly aware of the importance of nature and are creating new kinds of “parks” out of empty spaces. There’re also more city gardens where people can grow vegetables. For kids, kitchen gardens in schools are becoming popular. As Miyazaki stresses, you don’t have to find a formal park or garden to practice shinrin-yoku. Instead, you can enjoy the effects of nature wherever there’re plants.Better yet, he says, we can bring nature closer to where we spend most of our time. Miyazaki’s research has shown that just increasing the amount of plants in a room can affect the relaxatio n benefits of the room. What’s more, even when people simply look at flowers, their bodies relax and stress levels decrease.24. What can we infer about the power of nature on human health?A. It is well accepted all the time.B. It is widely used in the medical field.C. It is a popular topic of research.D. It was put forward by a Japanese scientist.25. Why does forest bathing work effectively according to Miyazaki?A. Human bodies fit in with nature.B. Nature is part of the modern society.C. Human genes do not change easily.D. People can always calm down in nature.26. What do you think of Miyazaki’s opinion about forest bathing according to the last two paragraphs?A. It is easily affordable.B. It is convenient to practice.C. It is not difficult to learn.D. It is meant for gardeners.CIf you love eating and drinking for free and are looking to make some pocket money, there's a job in China with your name on it. A new type of online service allows people to hire others either to eat or drink their favorite treats or satisfy their appetite without the calories that usually come with it.Chinese media recently reported on an increasingly popular service on online platform Taobao that's as startling as it is appealing. People can now go online and hire others to consume certain foods and drinks, and ask them to provide video evidence of them eating or drinking the said treats.Fees usually range from two to nine yuan ($0.30 - $1.35) plus the cost of the food. It's not exactly a get-rich-quick job, but there are quite a lot of people willing to do it for the free treats alone.“Bubble tea drinking" is a particularly popular service, as the chewy tapioca(木薯粉) balls and popping drink is all the rage in Asia these days, but there are also ads from people willing to eat fried chicken or hot pot for anyone willing to pay for them.Advertised as being "fat-free" and "free of queues", those who pay for the service will receive the full experience, which includes a 360-degree video of the drink, photos, and a detailed description. Prices of the service are based on the drink's sweetness level, its price, and popularity. Some clients even require a short written review to be sure that the person they hired actually does what they are supposed to.Sellers explained that most customers buy their "Bubble tea drinking" service maybe because they're trying to shake off desires while they're on a diet. Drinking bubble tea by proxy may help customers avoid high blood pressure, high blood sugar, and other health problems that the sugar-laden drink may cause.So why would anyone pay a total stranger to enjoy a treat rather than consume it themselves? Well, apparently, the online service is so cheap that some people simply do it out of boredom, while others get satisfaction from watching others indulge in their favorite treats.This indulging-by-proxy service(代享受服务)has received a lot of attention on social media in China, with some people describing it as the job of their dreams.27. What kind of people may buy the new type of online service?A. Those who are trying to lose weight.B. Those who are boring.C. Those who love eating and drinking for free.D. Those who are looking to make some pocket money.28. Which is the reason for many people being willing to be hired for the new job?A. That they can make a fortune.B. That the foods and drinks are cheap.C. That they can consume the treats for free.D. That they can realize their dreams.29. Why does the author mention "bubble tea drinking" in Paragraph 4?A. To prove that the new type of service online is popular.B. To list an example of the new type of service onlineC. To show bubble tea is greatly welcome in Asia.D. To promote the new type of service online.30. What is the main idea of the passage?A. Indulging-by-proxy service online helps lose weight.B. Boredom leads to indulging-by-proxy service online.C. People hold different opinions on indulging-by-proxy service online.D. Indulging-by-proxy service online is getting increasingly popular.DO’Brien and Samantha Kassirer from the Northwestern University Kellogg School of Management conducted two experiments to determine the levels of people’s happiness when they gave away money or when they spent it on themselves.The first experiment involved 96 college students receiving $5 every day for five days. They had to spend the money on the same thing each day. Researchers randomly asked the participants to either spend the money on themselves or give it to someone else, like through a tip or an online donation to charity. The participants ended each day by reflecting on their spending experience and their overall level of happiness. Regardless of how they spent the money, everyone started off with roughly the same level of self-reported happiness. Those who spent the money on themselves, however, experienced a decline in happiness over the five-day period. The people who gave the moneyto someone else maintained their happiness levels.A second experiment, this one conducted online, involved 502 people playing 10 rounds of a word puzzle game. Each round the player won, they received 5 cents. The participants could either keep the 5 cents or donate it to a charity. After each round, people rated the level of happiness they felt after winning a round. As with the first study, those who gave away the money reported a longer stretch of happiness than those who kept the money for themselves. As for why people who used the money for themselves aren’t as happy as long, the researchers explain that focusing on an outcome — like getting paid — can diminish (削弱) the experience. When people focused on an action — like giving to charity — they concentrate more on the act itself as a joyful event, explaining why happiness stayed more consistent among those who spent the money on others. “If you want to sustain happiness over time, our new research shows that repeated giving, even in the same way to the same people, may make you continue to feel much fresher and more enjoyable,” Ed O’Brien said.So the next time you think about spending on yourself, maybe give it to someone in need instead. Your happiness will thank you.31. What is the best title for the text?A. Money isn’t the key to happinessB. It is better to give than to receiveC. Happiness depends upon ourselvesD. People spend their money differently32. What is the finding of the experiments?A. People got more happiness when giving money to others.B. Those who give money to others like to do it online.C. Your level of happiness can be influenced by many factors.D. Those who won rewards are willing to give money to a charity.33. According to Ed O’Brien, what is the secret to maintain happiness?A. Saving enough money.B. Trying something new.C. Keeping on giving.D. Balancing rest and work.34. Which of the following shows the correct structure of the whole text?A. B. C. D.第二节(共5小题,每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,并在答题卡上将该项涂黑。
