For example, if a child is given a mobile phone with a tracking(追踪) device, his parents can find out 15 he is going with the help of the mobile phone.However, there are also some bad 16 of technology.

Pen, pencil, eraser, ruler…, and don't forget a bottle of water!According to a study at the British Psychological( 心理学的) Society Annual Conference held in London, students who bring water into exams may improve their grades by up to 10 percent.Scientists at the University of East London and the University of Westminster, UK, did a study on 447 students. The students were studying for different degrees(学历) at the University of East London. Only 25 percent of them entered the exam hall with something to drink.Scientists then compared their exam results with their normal schoolwork grades. They found that all those who had brought drinks with them got better grades by between 2 and 10 percent.It is unclear why drinking water improves exam results. But scientists say having enough water in our bodies and not feeling thirsty could have a helpful effecton our brains. Drinking water may also cut down on anxiety(焦虑), which has a bad effect on exam performances, according to Chris Pawson, PhD, of the University of East London."Whatever the explanation, it is clear that students should try hard to stay hydrated(含水的) with water during exams," he said.So next time, when you are going to have a big exam, try bringing a bottle of water with you. Who knows—it may help you pass the exam!21. How much may the students improve their grades most if they bring water into exams?A. By 2%.B. By 8%.C. By 10%.D. By 25%.22. How many students in the study got better grades?A. About 112 students who brought drinks or water into their exams.B. All the 447 students who come from the University of East London.C. About 300 students who took part in the study.D. About 10 percent of the students who studied different subjects.23. The underlined phrase "cut down on" probably means .A. increaseB. bringC. reduceD. change24. According to the passage, how does water help students in exams?a. It is good for their brains.b. It makes students smarter.c. It helps students stay cool.d. It helps students stay awake.A. a bB. a cC. b cD. c d25. Where can you probably read the article?A. Fashion magazine.B. Text book.C. Travel guide.D. Newspaper.BHave you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that aren't very smooth rub together to make heat energy. The faster you rub two things together, the more friction (and heat) you can make. Let's discover friction!WHAT YOU'LL NEED:● Soap ● Water ● Your hands!WHAT TO DO:①Make sure your hands are dirty.②Rub your hands together until you feel the heat of your hands.③Now, use soap and water to get your hands very slippery(滑的).④Try to make friction happen while your hands are slippery.⑤Please write down what has happened.LET'S TALK!Friction is an energy that happens when two things tub together. When friction happens, it makes heat! When your hands are slippery, they won't make very much friction and your hands won't get so hot.DID YOU KNOW?● Friction happens when you stop your fast running bike.●Ancient people made fires by rubbing two pieces of wood together. Friction happened though they didn't know it.Friction is everywhere. Have you ever noticed situations where friction is happening? If not, ask your parents to take you out in a car. If it is not hot, touch the tires(轮胎) of the car before and after a short drive to see how much warmer they get from friction.26.

What's the last column(栏目)?A. THINK IT OVER!B. WHAT HAPPENED?C. EVERYDAY ACTIOND. WORK WITH PARENTSCWe often praise the world of science.It explains the world and makes our lives easier with technology. One of the most exciting fields in science is artificial intelligence (人工智能,AI). This is an area where scientists are working on creating machines that think like humans. However, one of the most famous scientists has a very dark warning for us about this type of technology."The development of full artificial intelligence could spell the end of the human race," said Professor Stephen Hawking to the BBC.Hawking is a well-known British physicist and author of bestselling science book A Brief History of Time.This warning came after commenting(评论) the technology he uses to speak with. As Hawking has got a serious disease called ALS, he needs an AI computer to communicate. The computer learns how Hawking thinks and suggests the words he may want to use next.This is a basic type of AI, which is very useful, yet Hawking fears the possibility of creating technology that can match or surpass human intelligence. And it's easy to imagine how terrible things may be. Many TV shows and films show big, killer machines that are far cleverer than us. "Humans, who are limited(限制) by slow biological evolution(进化), couldn't compete," said Hawking.But not every scientist is pessimistic(悲观的) about AI technology. "I believe we will be in control of the technology for a long time," said Rollo Carpenter, creator of Cleverbot in the UK, which is a software program that remembers past conversations, "The advantages of it to solve many of the world problems will be realized."In what direction do you think AI is heading? Should we be hopeful or fearful?31. Which of the following is TRUE about AI?A. It makes our lives easier.B. The technology is not very popular now.C. Scientists haven't controlled the technology.32. The writer took Hawking as an example to .A. explain how AI has helped usB. show AI has already become part of our lifeC. suggest that AI might become dangerous for humans33. What does the underlined word "surpass" mean in the passage?A. 象征B. 促进C. 超越34. We can know from the last paragraph that .A. Rollo agrees with HawkingB. Rollo is a British creatorC. Rollo invented Cleverbot in the US35. Which of the following can be a suitable title for this article?A. AI: A Friend or an EnemyB. The Future of Human BeingsC. The Fight Between Humans and AIDDNA is the whole "map" of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.People have been trying to understand the human body for a long time. In I860, Mr Mendel discovered why we look the same as other people in our family. It is because of small things called "genes"(基因) in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages. They're written in the DNA with a special language.In 1961, another two scientists found the first "word" that they could understand in that language. It shows how DNA tells the cell(细胞) to build its parts, the words in the DNA map, but we still do not understand what they all do. By understanding what just one "word" means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do.Most people hope that this will help to make better medicine and help sick people: Other people worry that when we can more "words" and find out more information, we will use it in the wrong way, just to make people more attractive(有吸引力的), or stop sick people getting jobs.36.

How can we help sick people if we understand more "words" in the DNA map?A. Make better medicine.B. Make them get jobs.C. Make maps for them.D. Make them attractive.39. Which one is not true according to the article?A. We look like our parents because of "genes" in our body.B. We have understood what all the words in the DNA map do.C. DNA is the whole "map” of the human body.D. DNA tells the cell to build its parts.40. What do people think about this research about DNA?A. It can be only bad.B. It can be only good.C.
