You may have known several kinds of police --- traffic police, fire police and street police. But have you ever heard of energy-saving(节能) policeman?
A group of 22 energy-saving policemen went to work last week in Beijing. They go around the city to see the use of energy in hotels, office buildings, shopping centers and other public places. One of their aims is to make sure that these places have set their air conditioning(空调) no cooler than 26℃.
They also set up a special phone line so that people can tell them which buildings fail to follow the rule.
“If everyone sets their air conditioning at 26℃, Beijing will save 400 million kilowatthour of electricity in one summer. That’s one-third of all the usages of the city in the season,” said a TV advertisement.
Other Chinese cities, like Wuhan in Hubei Province and Yangzhou in Jiansu Province, are going to follow Beijing’s steps in setting up a similar police team.
As one of the fastest developing countries, China is using a lot of energy. This has a great effect on the country’s environment and limited(有限的) energy.
From 1986 to 2005, the country experienced 20 warm winters continuously(连续). Numbers show that Chinese cities have to spend billions of yuan solving environmental problems every year.
At the beginning of this month, China made its first action plan to fight pollution. It aims to reduce energy usage by 20% and increase renewable(可更新的) energy up to 10% from 7% by 2010.
To introduce the public to a green life, last week Beijing held a show on energy-saving technology and productions. Environment-friendly machines, such as a vending machine that helps collect used bottles, have attracted lots of attention. “We want to tell people that there are certain ways to protect the environment. Each of us can find effective ways to do it on our daily lives,” said Liu Qianguang, an environmental engineer in Beijing.
【小题1】The job of the energy-saving policemen is ______.

A．to set up a special phone line

B．to set the air conditioning cooler

C．to check the use of energy in public places

D．to make sure that more energy will be produced

Life for Cathy Taylor’s three children is very busy. Their school days are busy enough. After school, though, Cathy takes the two boys from football to basketball. Then she has to take her daughter to piano lessons. The tired children don’t get home until 7 pm. They have a quick supper, and it’s time for homework.
The Taylors are like many American and British parents. They take their children from activity to activity, and try to fit as much as possible into their kids’ lives. Doctors say many children are under too much pressure. Teachers complain(抱怨) about teaching tired kids in the classroom.
Most children take part in after-school clubs. Activities include sports, language learning, music and math classes. Pushy parents are nothing new, but now parents seem to push their children a lot more. Parents see other children doing a lot of things, and they feel their own children should do the same.
Linda Miller, a mother of three in London, knows all about such pressure. “In some families, competition starts from a very young age,” she says. “Mothers send their kids to all kinds of classes when they are very young. And they are always comparing them with other children. It’s crazy. People shouldn’t push their kids so hard.
Dr Alice Green agrees. She also says that these children may find it hard to think for themselves when they are older. “Parents are trying to plan their kids’ lives for them. When these kids are adults, they might find it difficult to plan things for themselves.” Parents should learn to give their kids a bit more time to themselves. On one hand, children need organized activities. On the other hand, they also need time and freedom to relax, and they need time to do things by themselves.
(   ) 8. Cathy Taylor sends her daughter to       .
A. math classes      B. language school B. sport club       D. piano lessons
(   ) 9. Why do teachers complain about teaching those children in the classroom?
A. Because they are very tired.     B. Because they know a lot of things.
C. Because they are under too much pressure. D. Because they can’t plan things for themselves.
(   ) 10. From the passage, we know children take part in after-school activities because       .
A. they have interest in them            B. their teachers tell them to do so
C. their parents push them to do so          D. they see other children doing these things
( ) 11. The writer probably thinks that parents should       .
A. compare their children with others    B. plan their children’s lives for them
C. take their children to different classes
D. give children time and let them do things by themselves
