7.According to a survey,taking a bottle of water into the exam hall could help students do better in their exam.
A study found that those who brought drinks,especially water,with them as they sat their exams performed at least 10per cent better than those who did not.
Psychologists(心理學家) said it was unclear why drinking water would improve your performance but said that enough water could have a helpful influence on the brain.
They studied hundreds of students in middle schools and universities.Their study,presented at the British Psychological Society annual conference(年度會議) in London,showed that those who brought drinks in with them averaged(平均) ten per cent better in exams.
For students in middle schools,grades improved by 12per cent while there was less influence on those in universities.
Mark Gardner of Westminster University,one of the researchers(研究者),said,"It proves that the effect is larger for younger students.We think it could be important-those students could be more worried and the water is having an active effect on exam pressure".
"Or it could be that the younger students might not eat as healthily,possibly stayed up late the night before,and might need to drink more water to stop them being dehydrated."
