When you cut your skin，you bleed．If a person loses a lot of blood，he will become ill and may die．Blood is very important．People have always known that．At one time，some people even drank blood to make them strong!
When doctors understand how blood goes around inside the body，they try ways of giving blood to people who need it．They take blood from the healthy people and give it to people who need it．This is called"blood transfusion"（输血）．The blood goes from the arm of the healthy person into the arm of the sick person．
But there are two problems．First，it does not always work．Sometimes people die when they are having blood transfusion．Later，doctors find that we do not all have the same kind of blood．There are four main groups of blood﹣﹣﹣O，A，B and AB．Almost all of us have blood of one of these groups．They also find that they can give any of the four groups of blood to people to people of group AB．But they find that they must give A﹣group blood to A﹣group people and B﹣group blood to B﹣group people．I have O﹣group blood and the doctor told me that I could give blood to anyone else safely．
There is another problem．To give blood of the right kind，doctors have to find a person of the right blood group．Often they can not find a person in time．If they have a way to keep the blood until someone needs it，they can always have the right kind of blood．At first，they find if they make it very cold，they can keep the blood in bottles for fifteen to twenty days．Then they find out how to keep it longer．In the end they find a way of keeping blood for a very long time．
We call a place where we keep money a"bank"．We call a place where we keep blood a"blood bank"．One day，when you grow up，you may decide to give blood to a"blood bank"．In this way，you may stop someone from dying．Or perhaps one day you may become ill．You may need blood．The"blood bank"will give it to you．

It’s the end of class. When the bell rings, students of Luohu Foreign Languages School in Shenzhen quickly take out their cell-phones. They want to log on (登录) to their microblogs (微博) to check the funny things that have happened in the last hour. Since last year, the trend (潮流) of microblogging has swept the country. Recent surveys show that most students in middle schools have a microblog, and some even update(更新) their blogs over five times per day.
“We learn many fresh and interesting things on microblogs and they have become popular topics in class,” said Liang Jianmin, 14, a student at Harbin No 3 Middle School. “If you do not know about them, you are out of the loop (被排挤在圈外).” It is also a great place for students to let out stress. “My parents always ask me to study hard, and encourage me before exams, but actually it adds pressure (压力),” said Zhang Yazhe, 15, a student in Luohu Foreign Languages School. “When I share these feelings on my microblog, I get many replies from friends in the same situation, which makes me feel better.” But parents are worried that microblogging could be a waste of time. Some misleading（误导性的） messages may even cause danger to kids, they said.
Shen Mingde, a professor at the China Education Association, suggests parents not worry too much as long as kids are not crazy about microblogging. Instead, it can become a window for parents to understand their children.
“If parents can read their children’s microblogs, they’ll know their thoughts, thus (因而) leading to better communication and solutions to problems,” he said. Micro blogging tips for kids
★1. Don’t microblog for more than one hour a day.
★2. Never microblog in class.

Maybe most people know that there is water pollution, air pollution and noise pollution around us, but few people know that there is another kind of pollution—light pollution. In fact, it can be everywhere, depending on the time of the day.
Light pollution is the result of the wasted energy. Instead of providing light for people on the earth, most bright light shines into the sky, because people don’t design lights very well. At the same time, lights are brighter than necessary. All these cause light pollution. Stars in the night sky always provide everyone with wonderful sights(景色), but light pollution prevents them from being seen.
Some scientists say that light pollution can also bring some health problems to people, especially to kids. So it’s the high time for us to do something useful to stop light pollution.
根据短文内容，判断下列句子的正(T)误(F)。Light pollution isn’t serious enough for us to stop it now.
All the people know light pollution well today.
Most light shines into the sky instead of providing light for people.
People in big cities can’t see stars clearly in the night sky.
Light pollution doesn’t do harm to people’s health.
Can animals be made to work for us? Some scientists think that one day animals may be taught to do a number of simple jobs. They say that in a film or on TV .We may see elephants, or monkeys, dogs, bears, or other animals doing a lot of things. If you watch carefully, you may find that those animals are always given something to eat in return(作为回报) for doing them. The scientists say that many different animals may be taught to do a number of simple jobs if they know they will get something to eat in return.
Of course, as we know, dogs can be used to guard a house, and elephants can be used to do some heavy jobs. And we can also teach animals to work in factories. Apes(猿猴), for example, have been used in America to help make cars and scientists believe that these large monkeys may one day get in crops(收割庄稼) and even drive trains.Elephants can be used to do some heavy jobs because ____.
