What should you take with you when you take
an exam? Pens, pen an eraser, a 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 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(学位) 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 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 (焦虑)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!
