If you have a bottle of water recycled(再利用) from urine(尿), would you drink it? Astronauts at the ISS may soon do so.
NASA(美國航空航天局) said it would use a high-tech machine to recycle wastewater at the ISS. The machine will recycle water for washing hands, shower water, water for brushing teeth and even urine to make drinking water. It will save millions of dollars each year.
At present, each ISS astronaut uses about 4.4 liters(升) of water every day. It costs about 24 million dollars a year to send water up to the ISS. A liter of water costs about $ 11,000.
The machine will be sent to the ISS later. NASA hopes it will recycle about 93% of all the water used on the station.
Will the water be clean? Different chemicals will be put in the wastewater. The water will be heated to 130℃ to kill bacteria(細菌). Scientists say that the recycled water is thousands of times better than the water from a city tap.
小題1:NASA will use a high-tech machine to recycle wastewater at the ISS to ______.

Fashions in child-care (兒童保育)， as all parents know, come and go. Bottle-feeding or mother's milk?  Full-time parental care or a child-minder(兒童保育員)? These problems always trouble the parents a lot. And now, there is a book called Childsplay dealing with the problem of child-care.
The author of Childsplay, Lucy Jackson, believes most school children do some sports at school. And many adults take regular exercise in their free time.
Babies, though, spend most of the time in front of the television or sitting in a push-chair (折疊式嬰兒車) or high chair. If the world were a safer place, every child would run around freely, but that is simply not possible. As a result, they become lazy, overweight and unfit.
Ms. Jackson is worried that if small children take no regular exercise, bad habits will continue into adulthood (成人期 ). She suggests that parents should begin exercising with very small babies, moving their legs and arms gently in time to music. As children grow, they should follow and exercise program using soft balls, household furniture and play equipment.                                    
Many experts in child development do not agree. They feel that children will learn to run and jump as they play naturally; they do not need planned exercise. They would not be overweight if they ate healthier food. An increasing number of parents, though, are taking their children to exercise classes. The kids jump around with their mothers to disco music.They seem to enjoy themselves, but it is not at all clear if the classes have any effect on their future development.
小題1:According to the passage, the parents do not worry about how to care about their children.
小題2:Childsplay is a book about how to take care of the children.
小題3:Ms. Jackson doesn't believe babies take enough exercise.
小題4:Ms. Jackson encourages parents to take exercise with their babies.
小題5:Though we don’t know if the exercise will have any effect on children future development, some mothers have already taken their children to exercise.

There are many wetlands（濕地） in China and some of them have become the world‘s important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng， Jiangsu Province. They are home for many different kinds of birds and animals. The world’s largest Milu Deer Nature Reserve（自然保護區(qū)） is in them. More than 700 milu deer live freely there. There are not many red-crowned cranes in the world， but every winter you can see some in the Red-crowned Cranes Nature Reserve in the Yellow Sea Wetlands.
The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine， too. They are really good places for wildlife（野生生物）。 Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.

What can you do on the Internet? Many of us like to read the news, buy things and play games. Some students now have a new use for the Internet – helping them with their homework.
Tina, 14, from Shenzhen, Guangdong, often searches online for the answers to her math problems. She said sometimes she and even her parents don’t know the answers to the problems, so she has to turn to the Internet.
“I can see how other people work out these problems and learn from them,” Tina said. “It’s easy and saves time.”
But not all the students welcome this. Leo, 15, from Hangzhou, Zhejiang, thinks it may make students stop thinking.
“We should think over the problems first. Simply copying the answers won’t improve our abilities. ” he said.
In the eyes of Wang Zhaoming, a Shanghai teacher, the success of all this is down to the students. If they use the Internet properly (適當?shù)?, it could be a good tool for study, Wang said.
“Students should first think about the problems by themselves. As for the online answers, they should choose the best among different ones. The most important thing is to know the logic (邏輯) behind the answers,” he said. “Don’t be shy to ask teachers and classmates the next day if you don’t understand the answer.”
小題1:According to the passage, it’s a new use for students to ___________ on the Internet.
A．buy thingsB．play gamesC．help with homeworkD．read news
小題2:The right order to use the Internet to help with our homework is ____________.

③ Think about the problems by ourselves;
④ Try to understand the logic behind the answer you’ve chosen.
A．①②③④B．③②①④C．②③①④D．④③②①
小題3:In Leo’s opinion, searching online for the answers may _______________. 
A．make students simply copy the answers instead of thinking
B．help solve the problems between students and their parents
C．be a good tool of study if students use the Internet properly

Food waste has become a big problem in China.
Zhou Jinsong, a canteen(食堂) manager at Central South University, said that students produce over 12 barrels(桶) of leftovers every day — each barrel stands at one meter in height. Zhou’s canteen is just one of several on the campus.
According to Xinhua News Agency, the food wasted by Chinese people equates to about 50 million tons of grain every year, or 10 percent of the country’s total annual grain production. This food could feed another 200 million people. What students waste every year could feed over 10 million people. Students nowadays are well protected by their families and hardly know how hard farmers work to provide them with the food they eat.
“Since the 1980s, when Chinese gradually became richer, food waste has been a subject of debate. But things have hardly changed over the years,” said Yu Changjiang, a sociologist at Peking University. “It’s the Chinese way of showing respect to friends, often referred as Mianzi.”
But rather than tradition, huge public spending on government banquets(宴會) is also causing food waste, said Zhou Xiaozheng from the sociology department at Renmin University of China. “It’s the result of widespread reception meals at government levels. It is also important that everyone thinks about how they can do their best to reduce food waste.”
小題1:Which of the following statements is not the reasons for food waste?
A．Students hardly know farmers’ hard work on the farm.
B．The government spends a large amount of money on government banquets.
C．Leaving some food after a banquet is the Chinese way to show respect to guests.
D．The food in the college canteen is not delicious.
小題2:Where can we probably read this passage?
A．In a newspaper.B．In a traffic report.
C．On a health website.D．In a story book.

Do you know why different animals or pests have their special colors? Colors in them seem to be used mainly to protect themselves.
Some birds like eating locusts. but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you'll find the main use of coloring is protecting themselves. Bears, lions and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colors much like the tree.
Have you ever noticed an even more strange act? A kind of fish in the sea can send out a kind of very black liquid when it faces danger. While the liquid spread over, the enemies cannot find it. And it immediately swims away. So it has lived up to now though it isn't strong at all.
