21、 The brain, like any other body part, gets old. 【1】 For example, women’s brains may age more slowly than men’s. That is the finding of a U.S. study from Washington University School of Medicine.
Researchers there wanted to find out how the brain uses sugar. 【2】 They used medical equipment to look at the flow of oxygen and sugar in the brains. The researchers found that the brains of women looked nearly four years younger than those of men. 【3】
As our brains age, some mental problems may happen. However, doctors say that about half of the problems can be prevented by simple lifestyle changes.
Whether you are a man or a woman, here are some tips for you to keep your brain young and healthy.
·【4】 Experts suggest around seven hours of sleep each night.
·Get aerobic (有氧) exercise for 30~40 minutes three to four times a week. Exercise helps grow brain cells(细胞)and gets better blood flow in the brain.
·Eat a healthy diet. 【5】 One example is the diet with lots of vegetables, fruits, grains, and fish.
·Do activities that make you excited and happy.
·Spend time with family and friends.
A.The researchers do not know why.
B.However, not all brains age the same way.
C.To do that, they studied over 200 brains of men and women.
D.Sleep is the best thing you can do to keep your brain young.
E.Doctors say any diet good for the heart is also good for the brain.
F.Parts of the brain get smaller, especially those important to learning.
G.The findings suggest the brains of men and women may use sugar differently.
22、 Scientists say only enlarging the world’s nature reserve to help protect plants and animals may be useless. The main reason is that levels of human activity are rising in and around the nature reserves. In fact, recognizing spaces as protected areas is not reducing human activity there.
The researchers found that a lack of money to pay for land conservation(保护)is affecting conservation efforts. And it is a lack of communication between people who live in protected natural areas and outsiders. About 17 percent of the world is within protected areas, including the national parks, nature reserves and wilderness areas. Protected areas are important for supporting environments with many different kinds of plants and animals.
The researchers again found increasing human activity in most protected areas in every country. However, they said that human activity appeared to be more of a problem in nations with fewer roads and lower life standards on the Human Development Index(指数). The index uses information about life length, education and earnings to grade countries on human development.
Across the northern Australia, protected areas often proved effective at slowing human activity when compared with unprotected areas. But in South America, Southeast Asia and African countries, pressure from human activity inside protected areas was higher.
Experts say governments need to provide fund support to help protected areas. Simply recognizing a place as a protected area can’t be the beginning and the end of a conservation effort. Working with local people to take efforts is also important. If they’re not partners in the protected areas, then wildlife conservation is much more difficult.
【1】What are protected areas mainly affected by according to the text?
A.Human activity. B.Climate change.
C.Population growth. D.Environmental pollution.
【2】What’s the Human Development Index used to do?
A.Record more roads in the world.
B.Improve education in all countries.
C.Grade countries on human development.
D.Lead more people to make more money.
【3】What can be the best title for the text?
A.People May Cause Harm to Plants and Animals
B.Nature Reserves May Not Protect Wildlife Safely
C.Nature Reserves in the World Should Be Increased
D.Local People Should Focus on the Natural Environment
23、AI software can already identify people by their voices or handwriting. Now, an AI has shown it can label people based on their chess-playing behavior, an advance in the field of “stylometrics” that could help computers be better chess teachers or more humanlike in their game play. Alarmingly, the system could also be used to help identify and track people who think their online behavior is anonymous (匿名的).
Chess-playing software, such as Deep Blue and AlphaZero, has long been Superhuman. But Ashton Anderson, a computer scientist at the University of Toronto, says the chess engines play almost an “alien (外星人的) style” that isn’t very instructive for those seeking to learn or improve their skills. They’d do better to tailor their advice to individual players. But first they’d need to acquire a player’s unique form.
To design and train their AI, the researchers collected more than 50 million human games and fed them into a network. The researchers tested the system by seeing how well it distinguished one player from another. They gave the system 100 games from each of about 3,000 known players, and 100 fresh games from an unknown player. The system looked for the best match and identified the unknown player 86% of the time, the researchers reported last month at the Conference on Neural Information Processing Systems (NeurlPS). “We didn’t quite believe the results,” says Reid Mcllroy-Young, a student in Anderson’s lab and the paper’s primary author. A non-AI method was only 28% accurate.
“The work is really cool,” says Noam Brown, a research scientist at Meta. “Style-aware AI could transform other computer interactions.”
The researchers are aware of the privacy risks posed by the system, which could be used to expose anonymous chess players online. And in theory, they say, given the right data sets, such systems could identify people based on the habits of their driving or the timing and location of their cellphone use.
NeuriPS organizers found the study technically impressive but ethically (道德上) questionable, and accepted it on condition that the researchers detail the privacy risks. Anderson says they’ve decided, for now, not to release the software.
【1】What advance in AI technology is described?
A.It can recognize different human chess players.
B.It can behave like humans when playing chess.
C.It can identify different people’s handwriting.
D.It can track people’s unacceptable online behavior.
【2】Why does Anderson describe chess engines’ style as alien?
A.They have remarkable but unhelpful ability.
B.They instruct players in an extremely unique style.
C.They have an advantage over individual players in skill learning.
D.They are outstanding in acquiring a player’s unique form.
【3】What does paragraph 3 mainly talk about concerning the new AI system?
A.Its significance to players.
B.Its development process.
C.Its wide application.
D.Its primary aim.
【4】What is NeurIPS organizers’ attitude toward the style-aware AI?
A.Favorable.
B.Disappointed.
C.Careful.
D.Uninterested.
24、A teenage girl writes to Choices magazine, asking for help with a problem, and other teens give their advice.
The Problem
Dear Choices, My mother never lets me go out alone with any of my friends. Every time I want to go out, she gives me an incredibly long and boring speech. When I try to state my totally reasonable case, we end up arguing. I'm a girl of 16. I think I'm absolutely mature enough to go out alone with my friends. What should I do?-Sara T. |
Four Replies
I think our moms might be twins. They're both so unfair. You should do what I do. Go out anyway. After all, you are 16! That's obviously old enough to go out alone with your friends. Naturally, I've made some mistakes. But I've learned from them. And so far, I haven't gotten into any trouble.-Steven E. Your mom's probably strict because she loves you. Naturally, she doesn't want you to go out without supervision because she's afraid you'll get hurt. You should definitely follow her directions. Remember that she loves you and that you're the most important person in her life. I know my mom feels that way about me!-JoséG. Your mom is not so reasonable, but perhaps you can work out some kind of compromise(妥协). Invite your friends to your house, and let your mom get familiar with them. Maybe you'll find some middle ground!-Maria M. I had the same trouble with my mom's rules at your age.(I'm 18 now.)Next time your mom gives you "the speech," say: "Mom, I know what you're saying, but let me explain my side." Then present your case. Tell your mom where you'll be, how long you'll be out, and who's going to be there. Then she won't be so worried about you.-Shawna S. |

26、阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
There are many things in senior middle school that I still remember clearly. I studied three years in a country school, which is faraway. However, it has a good environment and strict but kind teachers, so I loved the school and all my teachers very much. One Friday, just as we began to read books in reading class at our desks, our teacher, Mrs. Hill, said that she needed to be out of the classroom for a few minutes. She asked the class to read in silence while she was gone. And she said that those who didn’t read books in silence would have to answer to her when she returned. It was well-known that Mrs. Hill was strict. So we had to be on our best behavior.
But that Friday, Mrs. Hill hadn’t been gone for ten seconds before some students in the classroom started to talk. From one corner of the classroom I heard Josh ask Nick, “Can I trade my candies for your toy?” At the other end of the room I heard Samantha tell Kayla, “Let’s sit together on the bus for the museum field trip tomorrow.” And so it went all around me, until about half of the students talked with each other.
After a while, I, too, forgot about Mrs. Hill’s instructions. I turned back and asked my friend Liza, “Can I borrow your storybook and keep it for a day?” As soon as the words were out of my mouth, Mrs. Hill walked into the classroom. The whole class returned to silence immediately. And we were full of fear.
Mrs. Hill slowly looked around the classroom and said, “If you were talking while I was gone, then please stand up.” The guilt (内疚) suddenly weighed heavily on me. “I shouldn’t have talked while she was not in the classroom. And now I should be honest and admit my mistake bravely. This is what my parents have always told me, “I thought. Then, I summoned up (鼓起) my courage to stand up, worrying about the punishment that waited for me. Then I looked around.
