閱讀下面材料，從每題所給的三個選項（A、B和C）中，選出最佳選項。
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 (焦慮), 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!
小題1:According to the study, students who bring water to exams may ______.
A. get better scores
B. feel worried in exams
C. be smarter than others
小題2:How many students brought water during the exam in the study by the UK scientists?
A. 25.   B. 112.   C. 448.
小題3:Having enough water in exams ______.
A. makes the students smarter
B. helps the students stay calm
C. improves the students’ scores by 20%
小題4:The underlined word “predicted” means “______”.
A. 預(yù)測          B. 提高         C. 更正
小題5:What’s the best title for the passage?
A. The more water, the higher scores
B. Anxiety in the exams
C. Water helps in exams

What do you think is the most important invention in the world? The TV? The printer? The telephone? Or the computer? A report shows that they are not the only important inventions. Here are three other important inventions.
One of the simplest inventions is the toilet. Before toilets, people poured or dumped waste into rivers from people’s houses. Illnesses were common in big cities, and it was often difficult to find clean drinking water.
Animal food is another important invention. Before the invention, most animals were killed every autumn because there was not enough food for them in winter. After hay(干草) became a kind of common animal food, animals could live through the long winter.
The third great invention is glasses. Glasses help people read, write and do “close work” after the age of 45. Without glasses, the word would be difficult for the people above 45.
