Around the world more and more people are taking part in dangerous sports and activities. Of course, there have always been people who have looked for adventure-those who have climbed the highest mountains, traveled into unknown parts of the world or sailed in small boats across the greatest oceans. Now, however, there are people who look for an excitement from a risky activity which may only last a few minutes or even seconds.
I would consider bungee jumping （蹦极跳）to be a good example of such an activity. You jump from a high place (perhaps a bridge or a hot-air balloon)200 meters above the ground with an elastic (有弹性的) rope tied to your ankles. You fall at up to l50 kilometers an hour until the rope stops you from hitting the ground. It is said that two million people around the world have now tried bungee jumping. Other risky activities include jumping from tall buildings and diving into the sea from the top of high cliffs.
Why do people take part in such activities as these? Some psychologists suggest that it is because life in modern societies has become safe and boring. Not very long ago, people's lives were often in danger. They had to go out and hunt for food, diseases could not easily be cured, and life was harder than that of the present days.
Nowadays, according to many people, life offers little excitement. They live and work in safe environment; they buy food in shops; and there are doctors and hospitals to look after them if they become ill. The answer for some of these people is to look for danger in activities such as bungee jumping.More and more people today ______.
| A．are trying activities such as bungee jumping |
| B．are climbing the highest mountains |
| C．are coming close to death in sports |
| D．are looking for adventures such as exploring unknown places |
In bungee jumping, you ______.
| A．jump as high as you can |
| B．slide down a rope to the ground |
| C．tie yourself to a rope and fall to the ground |
| D．fall towards the ground without a rope |
People probably take part in dangerous sports nowadays because ______.
| A．they have a lot of free time |
| B．they can go to hospital if they are injured |
| C．there isn’t so much excitement in life. |
| D．they no longer need to hunt for food |
Which of the following is the best title for this passage?
| A．Modern Life is Boring |

Spending two or three hours playing outdoors each day can reduce the chance of becoming short-sighted(近视), a research shows. It challenges the belief(信念) that short-sightedness is caused by computer use, watching TV or reading in weak light.
The Australian government researchers believe that the sunlight is good for people’s eyes. They studied the vision(视力) and habits of 100 seven-year-old children in Singapore and Australia. In all, 30% of the Singaporean children were short-sighted—this rate(比率) was ten times higher than Australian children.
Both groups spend a similar amount(数量) of time reading, watching television and playing computer games. However the Singaporean children spent an average (平均) of only half an hour a day outdoors—90 minutes less than the Australian children.
Professor Ian Morgan, from the Australian Research Council’s vision Centre, said, “Humans are naturally long-sighted, but when people begin to go to school and spend little or no time outdoors, the number of short-sighted people gets larger. We’re also seeing more and more short-sighted children in cities all around the world and the main reason may be that city children spend less time outdoors.
Daylight can be hundreds of times brighter than indoor light. But why does playing outside prevent us from becoming short-sighted ? Scientists believe that natural light has a special chemical(化学物质) which stops the eyeball from growing out of shape and prevents people from becoming short-sighted.
So be outdoors. It doesn’t matter if that time is spent having a picnic or having sports.How much time did the Australian children spend outdoors on average according to the research?
| A．30 minutes. | B．60 minutes. |
| C．90 minutes | D．120 minutes. |
Which of the following is TRUE according to the passage?
| A．If people spend less time outdoors, they will certainly become short-sighted. |
| B．There are fewer short-sighted Singaporean Children than Australian children because they have more knowledge of protecting their eyesight. |
| C．There will be fewer risks of getting short-sighted if people spend two or three hours a day playing outside. |
| D．When people begin to go to school, they will become long-sighted. |
What is the fifth paragraph mainly about?
| A．Why natural daylight has a special chemical. |
| B．Why daylight prevents people from becoming short-sighted. |
| C．Why daylight is much brighter than indoor light. |
| D．What the special chemical which can stop eyeballs from growing out of shape is. |
Everyone has got two personalities---the one that is shown to the world and the other that is secret and real. You don't show your secret personality when you're awake because you can control yourself, but when you're asleep, your sleeping position shows the real you. At night, of course, you often change your sleeping position. The important position that best shows your secret personality is at the beginning of your sleep.
If you go to sleep on your back, you're a very open person. You often trust people and you are easily influenced by fashion or new ideas. You don't like to make people unhappy, so you never express your real feelings. You're quite shy and you aren't very confident.
If you sleep on your stomach, you are a person who likes to keep secrets. You worry a lot and you're always sad. You don’t want to change your ideas, but you are pleased with your life. You usually live for today not for tomorrow.
If you sleep on curled up(蜷缩), you are probably a very nervous person. You're shy and you don't like meeting people. You prefer to be on your own.
If you sleep on your side, you have usually got a well-balanced personality. You know your strengths and weaknesses. You're usually careful. You have a confident personality. You sometimes feel worried, but you don't often get unhappy. You always say what you think even if it makes people angry.When does the sleeping position best show your secret personality?
| A．In the daytime. | B．At the beginning of sleep. |
| C．At night. | D．During the deep sleep. |

Why do you think people in some hot countries eat very spicy（辛辣的）food? Is it because the spices make the food taste better? Is it just because their parents and grandparents and great-grandparents liked hot food，or is there any connection(联系) between spices and healthy food?
Scientists think that it is because spice plants have some important chemicals（化学物质）．These chemicals can kill bacteria（细菌）.
“Most common spices can kill 75 to 100 percent of the bacteria in food，”explains one of the scientists．The bacteria grow more easily and spoil（使…变质） food more quickly at higher temperatures．For this reason，it is more difficult to keep food from spoiling in hot climates，
Do you like your food spicy? Your answer probably tells something about the country you are from．If you like spicy food，it is possible that hundreds of years ago，when there were no fridges，people in your country started using spices to keep the food from spoiling．The traditional spicy dishes helped those people to live longer，healthier lives．Today，in a time of fridges，the spices just make the food taste better．The chemicals in spices keep food fresh by_________．
| A．making food taste better |
| B．making food hotter |
| C．preventing bacteria getting into food |
| D．killing bacteria in food |
Food goes bad more quickly in hot climates because_______．
| A．cold temperature makes bacteria |
| B．bacteria get used to hot food |

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 ( 心理学的) 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 (学历) 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 ( 焦虑), 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!How much may the students improve their grades most if they bring water into exams?
| A．By 2%. | B．By 8%. | C．By 10%. | D．By 25%. |
How many students in the study got better grades?
| A．About 112 students who brought drinks or water into their exams. |
| B．All the 447 students who come from the University of East London. |
| C．About 300 students who took part in the study. |
| D．About 10 percent of the students who studied different subjects. |
The underlined phrase “cut down on” probably means _______.
| A．increase | B．bring | C．reduce | D．change |
