YOLO Is More Than Just A Saying

Life is short, so you have to make the most of it. Has anybody ever told you that? Maybe they just said ―YOLO‖ to you instead. It 31 ―You Only Live Once‖ , and is a very popular phrase on social media.

Having a YOLO attitude(态度)means that you make the most of every day. It means you 32 your life, because you only get one. Someone who has a YOLO attitude is always open to doing new, fun activities.

Now, thanks to a US study, YOLO might be more than just a popular saying. A study found it might be healthier to have a YOLO attitude!

A research team did an experiment(实验)with two groups of 33 from different US universities. One group pretended they only had 30 days left before moving to a new city. They did lots of activities and spent time with people they loved. In other words, they had a YOLO

lifestyle. Another group continued to live normal lives.

At the end of the experiment the students did a survey to find out how happy they were. It showed that the 34 group was much happier.

―The study shows that being active and making close friendships are important to enjoy life,‖the research group told The Washington Post. However, they also called on others to do experiments with different groups of people and see if their finding were similar.

31. A. stands up B. stands out C. stands for D. stands by

32. A. enjoy B. waste C. hate D. live

33. A. teachers B. students C. doctors D. reporters

34. A. first B. second C. girl D. boy

B

Justin was always 35 . His motto(座右铭)was ―Never throw anything out, you never know when it might come in handy(派上用场).‖

When Justin was away from home, he always carried his blue backpack, which stores many objects that he collected. It was full of the kind of things that seemed

36 , but when used with a little imagination, might come in handy.

On the first day of school, his friend Kenny, came looking for Justin. ―Do you think you have something in your bag that could help me remember my

locker combination(保险锁的暗码)?‖he asked. ―I lost the 37 it was

written on. I have science class in two minutes and if I’m late on the first day

it’ll make me look bad for the rest of the year.‖ Kenny looked pretty worried.

―Relax,‖Justin said, taking his backpack off and open it. ―Remember how you borrowed my notebook in homeroom to write the combination down?

Well, I know how we can recover(复原;找回)what you 38 .‖He took the notebook and a soft lead pencil out of his bag. The page that Kenny had written on had left faint indentations(压痕)on another page in the notebook. Justin 39 the pencil on its side and rubbed(擦)it lightly over the indentations. Slowly but surely the numbers of the locker combination appeared in white, set off by the gray pencil rubbings.

―That’s amazing!‖ Kenny said. ―I owe you one.‖ And he rushed to open his locker.

During science class, Mr. Tran was lecturing on the structure of the solar system using a model. He made a sudden gesture and the model fell apart (散落). Planets and rings and connector rods went 40 , rolling and clattering and disappearing under desks. The students scrambled around on the floor for ten minutes and were finally able to recover every piece except one-a connector that was stuck in a crack (缝隙)between two lab stations.

―If we had a magnet(磁铁),‖ said Mr. Tran, ―we could easily get it out that way. But I lent all of the magnet kits to the elementary school yesterday.‖

Justin was already searching through his 41 . ―I have some materials that will work just as well, I think,‖ he told Mr. Tran. He pulled out a battery, an iron nail, and some electrical wire and tape, while Mr. Tran and the other students looked on in amazement.

―Why do you have all of that stuff?‖ Louise Baxter asked. Justin just smiled and repeated his motto. ―Never throw anything out, you never know when it might come in handy.‖By wrapping(缠绕)the wire around the nail and taping each end to a battery terminal, he was able to make it 42 like a magnet to lift the rod out of the crack.

―Bravo!‖ said Mr. Tran.

―No problem,‖ said Justin.

It was just another day in the life of the boy whose motto was ―Never throw anything out,

you never know when it might come in handy.‖

期中英语考试卷及答案

英语期中考试试卷 Part I Reading Comprehension (10×4 = 40) Passage One Television has opened windows in everybody's life. Young men will never again go to war as they did in 1914. Millions of people now have seen the effects of a battle. And the result has been a general dislike of war, and perhaps more interest in helping those who suffer from all the terrible things that have been shown on the screen. Television has also changed politics. The most distant areas can now follow state affairs, see and her the politicians before tan election. Better informed, people are more likely to vote, and so to make their opinion count. Unfortunately, television's influence has been extremely harmful to the young. Children do not have enough experience to realize that TV shows present an unreal world; that TV advertisements lie to sell products that are sometimes bad or useless. They believe that the violence they see is normal and acceptable. All educators agree that the "television generations" are more violent than their parents and grandparents. Also, the young are less patient. Used to TV shows, where everything is quick and interesting, they do not have the patience to read an article without pictures; to read a book that requires thinking; to listen to a teacher who doesn't do funny things like the people on children's programs. And they expect all problems to be solved happily in ten, fifteen, or thirty minutes. That's the time it takes on the screen. 1. In the past, many young people ______. A) knew the effects of war B) went in for politics C) liked to save the wounded in wars D) were willing to be soldiers 2. Now with TV people can ________. A) discuss politics at an information center B) show more interest in politics C) make their own decisions on political affairs D) express their opinions freely 3. The author thinks that TV advertisements ______. A) are not reliable on the whole B) are useless to people C) are a good guide to adults D) are very harmful to the young 4. Which is NOT true according to the passage? A) People have become used to crimes now. B) With a TV set some problems can be solved quickly. C) People now like to read books with pictures. D) The adults are less violent than the young. 5. From the passage, we can conclude that _______. A) children should keep away from TV B) TV programs should be improved C) children's books should have pictures D) TV has a deep influence on the young Passage Two Many a young person tells me he wants to be a writer. I always encourage such people but I also explain that there's a big difference between "being a writer" and " writing". In most cases these individuals are dreaming of wealth and fame, not the long hour alone at a typewriter. "You've got to want to write," I say to them, "not want to be a writer". The reality is that writing is a lonely, private and poor-paying affair. For every writer killed by fortune there are thousands more whose longing is never rewarded. When I left a 20-year career in
