Pens, pen an eraser, a ruler, and don39。t forget a bottle of water. According to a study at the British Psychological（心理學(xué)的） Society Annual Conference held in London, students who bring water into exam halls may improve their grades by up to 10 percent. Scientists at the University of East London and the University of Westminster, did a study on 447 students. The students were studying for different degrees（學(xué)位） at the University of East London. Only 25 percent of them entered the exam hall with something to drink. Scientists then pared 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 said having enough water in our bodies and not feeling thirsty could have a positive effect on our brains. Drinking water may also cut down on anxiety （焦慮）which had a bad effect on exam performances, said Chris Paw son, PhD of the University of East London. Whatever the explanation is, it is clear that students should try hard to stay hydrated（含水的） 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!（1）How much may the students improve their grades most if they bring water into exam halls? A.By 2%B.By 8%C.By 10%D.By 25%.（2）How many students in the study got better grades? A.About 112 students who brought drinks or water into their exam halls.B.All the 447 students who came from the University of East.C.About 300 students who took part in the study.D.About 10 percent of the students who studied different subjects.（3）The underlined phrase cut down on probably means _______.
