2020届常德市第七中学高三英语期末考试试题及参考答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AIf you are sending a text message watching TV or listening to the radio, you may stop and give this your full attention. Multitasking shrinks (使.....萎缩)the brain? research suggests.A study found that men and womenwho frequently used several types of technology at the same time had less grey matter in a key part of the brain. University of Sussex researchers said, " Using mobile phones, laptops and other media devicessimultaneouslycould be changing the structure of our brains."Worryingly, the part of the brain that shrinks is involved in processing emotion. The finding follows research which has linked multitasking with a shortened attention span, depression , anxiety and lower grades at school.The researchers began by asking 75 healthy men and women how often they divided their attention between different types of technology. This could mean sending a text message while listening to music and checking e-mail, or speaking on the phone while watching TV and surfing the Internet. The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingu-late cortex (ACC)(前扣带皮层).Scientists have proved that brain structure can be changed on exposure to fresh environments and experience.Other studies have shown that training—such as learning to play magic tricks or taxi drivers' learning the map of London―can increase grey matter densities (密度)in certain parts.Experts have also warned of the harmful impact technology can have on our memory and attention span. The University of California team conducted a survey of more than 18,000 people aged between 18 and 99,and found 20%had problems with memory. Researchers were shocked greatly by the 14 % of 18 to 39-year-old people who also worried about their memories.Multitasking may shorten attention span, making it harder to focus and form memories, the researchers said, adding that youngsters may be particularly affected by stress.1. The underlined word " simultaneously" in Paragraph 2 means "________,"A. on one's ownB. at no timeC. at the same timeD. by accident2. All of the following are possible effects of multitasking EXCEPT________ .A. saving timeB. a shortened attention spanC. lower grades at schoolD. depression and anxiety3.

People are worried about their memories.BJerry Lawson had a love of science and invention from a very young age. And, with the support of his family and teachers, he took that love and helped change the world for billions of people, when he invented the modem video game cartridge.Both of Jerry's parents supported his love of science and invention. His father, a longshoreman, was a science fan and encouraged Jerry to always experiment with things. Jerry's first-grade teacher helped encourage him on his path to be someone influential similar to George Washington Carver, a great AfricanAmerican inventor. His first love in school was chemistry but he ended up liking electronics(电子学)even more.He earned an amateur ham radio license at age 13 and built his own radio station in his room, with an antenna hanging out of his window! Jerry earned money from fixing television sets, visiting people's homes for inhouse repair, and also working at local electronics stores. Jerry also made walkie-talkies and sold them to other kids. He spent many Saturdays at an electronics store that had all of the parts he needed for his inventions. He would use his small allowance and money he earned to buy parts to help fuel his inventions.When he was a young adult, Jerry joined Fairchild Semiconductor as an engineer. During this time, he created his own video arcade game(街机游戏),Demolition Derby, in his garage.A few years later, Jerry was asked to work on a secret project. Not even his boss was allowed to know what he was doing! What it turned out to be was that he was designing the Fairchild Channel F video gameconsole(游戏控制器)and leading the team that invented the video game cartridge. This was the first of its kind and enabled kids around the world to affordably play video games at home.Just like with automobiles,many advances have occurred since the inventionof video games. Video games are now one of the biggest forms of entertainment in the world. But all of this would not have been possible without the vision, passion, and skill of Jerry Lawson and his learn.4.

We also live in an age when discussing our feelings is encouraged. But when does it all become too much? With new crazes trending all the time, such as dance challenges and wearing a carpet as a dress, the question is: when can sharing become oversharing on social media?“Oversharing” has become associated with social media, but it isn'texclusiveto this platform. Imagine you head to a party and meet x k w someone. Within five minutes they have revealed private details about their life. While some of us may try to escape these people, according to marriage advisor Carolyn Cole, this form of oversharing could come from a strong desire to connect with someone. But how does this translate to social media?Dr. Christopher Hand, a lecturer in cyberpsychology (网络心理学),says the more details people disclose, the less sympathy we express when things go wrong. It seems that searching for sympathy by oversharing is generally considered as negative rather than the cry for help it could really be.However, Dr. Hand's research also seems to suggest that the more we post on a platform, the more socially attractive we become-provided that the posts that we bang out are positive. Even back in 2015, GwendolynSeidman PhD said that we should avoid complaining and being negative online. We should also avoid showing off, especially about our love lives. It makes sense-if your date is going “that well", would you really have time to share a photo with text?So, how can you know if you are oversharing? Well, why not ask your friends in real life. They would probably be happy to tell you if your posts about your breakfast or your complaints about your lack of money really are too much.8.

Sharing more details online can attract more sympathy.B. Oversharing negative experiences is equal to crying for help.C. Sharing negative posts can't help one become socially attractive.D. Oversharing isn't likely to happen online when things go wrong.11. According to the text, what should be avoided for online sharing?A. Reflecting on past bad manners.B. Showing a great many expensive goods.C. Writing a recipe for a balanced breakfast.D. Recording unforgettable moments with friends.DIn May this year, as part of our 150th anniversary, we asked readers aged between18 and 25 to enter an essay competition. The task was to tell us, in no more than 1,000 words, what scientific advance they would most like to see in their lifetimes, and why it mattered to them.The response was phenomenal: we received 661 entries. Some entrants hoped that science would make their lifetimes much longer than they can currently expect. Many looked forward to work that will end climate change. Others wanted to see advances in our understanding of human history, crop growth, space exploration, and medical technologies. The ideas were inspiring.The winner is a compelling essay by Yasmin Ali, a PhD student at the University of Nottingham, UK. Ali submitted a piece on Beethoven, her brother’s hearing loss and the science which she hoped would one day cure it. It stood out to the judges as a reminder of why many scientists do research: to make the world better tomorrow than it is today.All essays were judged by a group of Nature editors. The top ten submissions were then ranked by three members of a separate judging group: Magdalena Skipper, editor-in-chief of Nature; Faith Osier, a researcher; and Jess Wade, a physicist. All submissions were kept anonymous throughout the process.We also selected two runners-up(非冠军的获奖者).Physicist Robert Schittkoat Harvard University in Cambridge, Massachusetts, proposes that nuclear fusion(核聚变) could offer a solution to the climate crisis, in a piece that effortlessly mixes grand ambition with gentle humour. And chemist Matthew Zajac at the University of Chicagoin Illinois wrote a powerful personal account of why he wants to see advances in the field of same-sex reproduction.The results show that today’s young scientists have a wealth of ideas, talent and conviction that research can transform their world. We look forward to seeing what they do next.12. What’s the essay competition about?A. The scientific expectation.B. The fantastic scientific ideas.C. The dreams of future life.D. The celebration of anniversary.13. Why Yasmin Ali was chosen the winner?A. She showed great talent in music.B. She found the cure for the loss of hearing.C.
