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 at the British Psychological ( 心理學(xué)的) Society Annual Conference held in London, students who bring water into exams may improve their grades by up to 10 percent.
Scientists at the University of East London and the University of Westminster, UK, did a study on 447 students. The students were studying for different degrees (學(xué)歷) 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 say having enough water in our bodies and not feeling thirsty could have a helpful effect on our brains. Drinking water may also cut down on anxiety ( 焦慮), which has a bad effect on exam performances, according to Chris Pawson, PhD, of the University of East London.
“Whatever the explanation, it is clear that students should try hard to stay hydrated (含水的)with water 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!
小題1:How much may the students improve their grades most if they bring water into exams?
A．By2%. B．By8%.
C．By10%.D．By25%.
小題2:How many students in the study got better grades?

B．All the447 students who come from the University of East London.
C．About300 students who took part in the study.
D．About10 percent of the students who studied different subjects.
小題3:The underlined phrase “cut down on” probably means _______.
A．increaseB．bring
C．reduce D．change
小題4:According to the passage, how does water help students in exams?
a. It is good for their brains.

More than 50 music students of New Milford High School in New Jersey, US, got a letter from their headmaster. The letter said that the music department of the school was in big trouble. The students had to pass a test, or the department(系) would be shut down.
On a Saturday, two officials greeted the nervous students. They asked the students to play a piece by Richard Strauss. But they had to sing the words to the music – German words!
Other tasks were also difficult. One student had to sing Mary had a Little Lamb, a children’s song, in an operatic (歌劇的) voice.
After three hours of testing, students waited for the results. They met some students from the New Jersey Youth Orchestra (管弦樂團). The judges(裁判員) gave them only a passing grade.
The worried New Milford students started to realize they had no chance. “I thought it was over,” said Bryan Olsen-Santana, a junior. “The person next to me was crying. I felt bad for her. I felt bad for myself, too, because music is everything to me.”
But then the headmaster came and told them something very dramatic (戲劇性的): “Someone’s played a joke on you!”
What was going on?
The test was part of a reality TV show (電視真人秀) called “Schooled”. The students’ parents, the school and a TV network had made it together.
Everything was fake. The two “officials” were really comedians (喜劇演員). The “students from New Jersey Youth Orchestra” were from another school. There were hidden cameras. The students’ parents were hiding as they watched.
As a reward for putting up with the joke, the students got gifts: MP3 players, digital cameras and school supplies. They were all from the show’s sponsor (贊助商).
小題1:What is the letter about?
A．The headmaster would come back next term.
B．The school didn’t have money to run.
C．The music department was in big trouble.
D．The students had to give up music.
小題2:The students were nervous before the test, because _____.
A．they were not good at music
B．the judges were very strict
C．they thought they couldn’t pass
D．it would decide the future of the music department
小題3:According to Olsen-Santana, we learn that _____.
A．their school failed the test
B．he likes music very much
C．the test was just a joke
D．the girl next to him was sorry for herself
小題4:What does the underlined word “fake” mean in the passage?

C．受歡迎的 D．便捷的
小題5:The students didn’t get _____ as gifts.

Traveling by train is usually not easy in China. It can be hard to get a ticket. When you’re traveling to the railway station, you look at your watch, for you are afraid you will miss your train.
But there is good news for people traveling between Beijing and Shanghai. Construction (建設(shè)) on the express railway (高速鐵路) between the two cities started just before the Spring Festival of 2008. When it is finished by 2013, taking a train will be as easy as taking a bus.
“There will be trains every several minutes. Buying a ticket, getting through the checkpoint (檢查站) and taking your seat, will take just 10 minutes,” said an engineer.
There may be high-speed trains running at 350 kilometers an hour. The travel time between the two cities will decrease from 10 to about 5 hours. The trains will carry twice the present number of passengers.
The new line will be 1,318 kilometers long and go across specially built bridges. It will run along side the present line. There will be 21 stations in Hebei, Tianjin, Shandong, Anhui and Jiangsu.
“The cost of traveling by the express railway may be around 800 yuan. That will be more expensive than an ordinary train, but cheaper than by air.” Said Zhang Xiaoling, a Jiangsu government official.
According to Zhang, the higher price is caused by the large cost of the railway project. At about 200 billion yuan, the project may be even more expensive than the Three Gorges Project (三峽工程).

A．a(chǎn)t the end of this yearB．before the Spring Festival of 2008
