阅读下面材料，从每题所给的三个选项（A、B和C）中，选出最佳选项。
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 held in London, students who bring water into exams may improve their grades by up to 10%.
Scientists in UK did the study on 448 students. The students were studying for different degrees at the University of East London. Only 25% of them entered the exam hall with water.
Scientists then compared their exam results with their normal schoolwork grades. They found that all those who had brought water with them got better grades by 2% to10%.
Scientists also predicted the students’ scores according to their normal schoolwork. They wrote down their possible scores on paper before exams.
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 reduce anxiety (焦虑), which has a bad effect on exam performances.
“Whatever the explanation is, it is clear that students should try hard to stay hydrated (含水的) with water during exams,” one of the scientists said.
So next time, when you are going to have a big exam, try bringing a bottle of water with you. It may help you pass the exam!

The common Chinese greeting of “Ni chi le ma?” may soon be replaced(代替) by a new greeting: “Have you cleaned your plate?”
The Clean Your Plate Campaign began on the Internet in January, 2013. It calls on people to reduce food waste. China in recent years has experienced serious problems with wasted food. CCTV reported in January that the food Chinese people waste every year is enough to feed 200 million people for a year.
Chinese people are well-known for their friendly behavior towards guests. Many even feel that they lose face if their guests have eaten all the food.
It’s important for everyone to reduce food waste. However, wasting food is still a serious problem in China. We still have a long way to go.
President Xi Jinping is encouraging people to be less wasteful, and he told Party members to cut back on wasteful holiday banquets(宴会). He said they should be more careful when spending the people’s money.
Wasting food certainly goes against what Xi Jinping calls, “the Chinese tradition of being hardworking and thrifty(节俭).” Having a “clean plate” is just a traditional and important thing to do.
