Sun Liping, 6 , lives in a small village in Yunnan. Her biggest wish is to have running water in her home. All 35 families in Sun’s village have a serious problem--- they don’t have enough water. Every day, the villagers have to walk 20 minutes to get water.
Last year, the worst drought since the 1950s hit Yunnan, making more than 2 million people short of drinking water. This year, the drought is even worse.
Not only Yunnan, but many other provinces in China are short of water as well, such as Gansu and Qinghai.
According to a report on February 17, each Chinese person has about 28% of the world’s average（平均的） person’s amount of available(可用的) water. Two thirds of China’s cities are short of water and nearly 300 million people in rural areas don’t have safe water for drinking.
Every drop of water is important. Waste a drop of water a day and you lose a bucket(桶) a year. How can we use water in a smart way? Here are some tips for you to save water in your daily life:
1. Put plastic bottles of water in your toilet to cut down the water waste when you flush (冲洗) your toilet.
2. Don’t keep the water running while you’re brushing your teeth or washing your face and hands.
3. Use low-flow(低流量) shower heads .
4. Use a bucket to collect shower water while you wait for it to warm up.
5. Make your shower time shorter.

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 |
According to the passage, how does water help students in exams?
a. It is good for their brains.
b. It makes students smarter.

As a child, I was really afraid of the dark and of getting lost. These fears were very real and caused me some uncomfortable moments.
Maybe it was the strange way things looked and sounded in my own room at night that scared me so much. There was never complete darkness, but always a streetlight or passing car lights, which made clothes on the back of a chair take on the shape of a wild animal. Out of the corner of my eye, I saw the curtains(窗帘) seem to move when there was no wind. A very low sound in the floor would seem a hundred times louder than in the day. My imagination (想象) would run wild, and my heart would beat fast. I would lie very still so that the "enemy(敌人) " would not discover me.
Another of my childhood fears was that I would get lost, especially on the way home from school. Every morning I got on the school bus right near my home. That was no problem. After school, though, when all the buses were lined up along the street, I was afraid that I would get in the wrong one and be taken to some other strange places. On school or family trips to a park or a museum, I wouldn't let the leaders out of my sight.
Perhaps one of the worst fears of all I had as a child was that of not being liked or accepted by others. Being popular was so important to me then, and the fear of not being liked was a serious one.
One of the processes(过程) growing up is being able to realize and overcome our fears. Understanding the things that scared us as children helps us achieve greater success later in life._________ would scare the author at night.
| A．Streetlight and car lights | B．Wild animals and enemies |
| C．Moving curtains and wind | D．Strange sights and sounds |
