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!According to the study, students who bring water to exams may ______How many students brought water during the exam in the study by the UK scientists?Having enough water in exams ______The underlined word “predicted” means “______”What’s the best title for the passage? get better scores,feel worried in exams,be smarter than others,get better scores,feel worried in exams,be smarter than others,25,112,448,25,112,448,makes the students smarter,helps the students stay calm,improves the students’ scores by 20%,makes the students smarter,helps the students stay calm,improves the students’ scores by 20%,预测,提高,更正,预测,提高,更正,The more water, the higher scores,Anxiety in the exams,Water helps in exams,The more water, the higher scores,Anxiety in the exams,Water helps in exams
