三、阅读理解（共15小题；共30分）
A
What should you take in with you when you take an exam? 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 effect on 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. increase B. bring C. reduce D. change
24. 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 b B. a c C. b c D. c d
25. Where can you probably read the article?
A. Fashion magazine. B. Text book.
C. Travel guide. D. Newspaper.

Have 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. This text is most probably ?.
A. a science report B. a car advertisement
C. a rubbing introduction D. a chemistry programme

A. slippery B. dry C. wet D. smooth

DNA 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.

Shopping online is quite popular in our daily lives now, because there are many advantages. First, it is so convenient that we don't need to go outside to buy things we want. Second, the shops online are open 24 hours every day, so we can buy the goods any time and needn't wait in line. But there are also many disadvantages of shopping online. We just see the pictures of the goods, so we may be cheated sometimes. We can't enjoy the time of shopping with friends.
In my opinion, we can shop online if the things we want to buy are difficult to find. And we can go shopping with friends if we want to spend the free time.
