Many places in the world need more fresh water. Every country is trying to find ways to turn salt water into fresh. Why aren’t there many factories like the Symi（锡米岛） factory?
In some places, the sun is not hot enough. Or it does not shine every day. In such places, other ways of heating sea water can be used. These ways cost more money, but they work faster than the sun. By boiling sea water with high heat, a lot of fresh water can be made quickly.
But heating is not the only way to get fresh water from salt water. Other ways are tried. One way is freezing. The fresh part of salt water freezes(冷至结冰)first. To get fresh water, the bits of ice are taken out.
Which way is the best ? The one that gives the most water for the least money. It may be a different way for each place.
Symi’s way seems very good for small, hot places. It doesn’t make very much water at a time. But the factory is easy to build and costs little. That is why people in many dry places talk about Symi !
1.From the passage we know that fresh water ________ .

In America, most people don’t get enough sleep. Children aged 5 to 12 are advised to sleep 10 to 11 hours every night, but most of them can’t sleep that long. A study found that about 41 million American workers got less than six hours of sleep every night. Scientists worry that parents are passing their bad sleeping habits down to their children.
In the study, Reut Gruber and some other scientists either added or reduced on hour of sleep for healthy children aged 7 to 11. They watched the children for five nights. They wanted to know if the amount of sleep can affect a child’s behavior.
Before the study began, students were asked to sleep the same amount of hours as usual. Their teachers were asked to record their behavior. After five nights of the records, scientists found that those who slept one hour less behaved worse than those who slept one hour more. Students with less sleep were more likely to feel sad and had more problems paying attention.
The scientists chose to study children in their homes instead of in a laboratory, because they wanted to find out how everyday changes might affect children’s behavior at school. “In the study, nobody became a talent, and nobody became crazy. But small changes in children can really make a big difference,” says Gruber.
1. Scientists worry that_______ may cause children to sleep less.
A. too much homework
B. pressure from parents
C. TV and computer games
D. parents’ bad sleeping habits
2. Scientists did the new study in order to know_______.
A. why children can’t get enough sleep
B. how long children should sleep every night
C. what children like to do before they go to sleep
D. if the amount of sleep can affect a child’s behavior
3. Who helped do some new study, children with less sleep_______.
A. Teachers. B. Parents. C. Scientists. D. Psychologists.
4.According to the new study, children with less sleep_______.
A. were more likely to feel excited
B. were more active in playing games
C. had more problems paying attention
D. didn’t want to answer questions in class
5.The new study was done in_______.
A. a laboratory B. a classroom
C. a children’s club D. the children’s homes
