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 ( 心理學的) 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 (學歷) 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 ( 焦慮), 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!
【小題1】How much may the students improve their grades most if they bring water into exams?

A.By2%.  B.By8%.  
C.By10%. D.By25%. 
【小題2】How many students in the study got better grades?
A.About112 students who brought drinks or water into their exams. 
B.All the447 students who come from the University of East London. 
C.About300 students who took part in the study. 
D.About10 percent of the students who studied different subjects. 
【小題3】The underlined phrase “cut down on” probably means _______.
A.increase B.bring 
C.reduce  D.change 
【小題4】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

Almost every Chinese person can recite the two lines of the famous poem, “Every grain on the plate comes from hard work(誰知盤中餐,粒粒皆辛苦).” But sadly, many of us don’t actually get the real meaning of these lines: Don’t waste food.
A CCTV program, News One Plus One, reported that the food Chinese people throw away every year is enough to feed 200 million people for a year.
Do we have too much food? Of course not. According to the UN World Food Program, there were 925 million hungry people around the world in 2010, especially in developing countries. Six million children die of hunger every year.
Chinese people are well known for being hospitable(好客的) and generous. Many even feel that they lose face if their guests have eaten all the food on the table.
Luckily, a number of people have realized the importance of saving food. Last November, Li Hong, a waitress in a restaurant in Nanjing, got fired because she took some leftover food home for her son. Many people stood by her side and criticized the waste of food.

What should we do in our daily lives to waste less food? Here are some tips:
1. Do not order too much in a restaurant. Only order as much as you want to eat. If you cannot eat all the food you ordered, take the rest of it home.
2. Don’t be too picky(挑剔的) about food. Some food may not taste great, but your body needs it.
3. Keep an eye on what food you have at home. Don’t buy too much, especially for vegetables and fruit.

A.Many Chinese restaurants waste a large amount of food.
B.Many Chinese people are kind-hearted and ready to help the weak.
C.Chinese people feel that they lose face if their guests eat all the food.
D.Many Chinese people don’t agree with the behavior of wasting food.
【小題3】The underlined word “leftover” means          in Chinese.
A.過期的B.剩余的
C.腐爛的D.難吃的
【小題4】According to the passage, we shouldn’t waste food because         .
A.food comes from very hard work
B.six million children die of hunger every day
