Karl Landsteiner first thought of naming blood types in 1900. He put blood into four types. These four blood types were named A, B, AB, and O. Blood type O is the most common around the world. Blood type A is the second most common. and type AB is the least common.
Doctors try to give blood to a person according to the person’s blood type. Blood type O can be given to a person with any other blood type, but doctors also need to make sure that the “RH factor (因子)” in patients’ blood matches the blood they are given. If people have one kind of protein (蛋白質(zhì))in their blood, they are RH positive (Rh+). If people do not have the protein, they are Rh negative (Rh-). Most people are Rh+.
If a mother has an Rh- blood type, she may have trouble when she has a baby. If her baby is Rh+, the baby’s blood may mix with the mother’s blood before the baby is born. The mother’s blood will change. If the mother has another Rh+ baby, the mother’s blood will attack the baby’s blood. The baby may die or become sick. Doctors have to watch the mother and baby carefully in these cases.

Now more and more people in the world are getting fatter. This troubles them a lot. （1）Experts(專家) say that it has a lot to do with our eating habits.
Our eating habits are very important for good health and a strong body. Most of us like eating sweets and ice cream better than vegetables and rice. Sweets and ice cream are not bad for us if we eat them at the end of a meal. （2）If we eat them before a meal, they may take away our appetite(食欲).
It’s important for us to eat our meal in the same period each day. When we feel worried or excited, we may not want to eat. A long time ago, in England, some judges(法官) often decided whether a man was telling the truth by giving him some dry bread. If the man could not swallow(吞) the bread, it meant that he wasn’t telling the truth. Because when a man is worried about something, he will have trouble in swallowing anything dry, because he loses his appetite.
小題1:Are more and more people getting fatter in the world?________________________       ___

Ted, my little brother, is in Grade One. Last Friday he came back from school with a letter.  The letter was from his teacher. "I got a red flower today. Could you please sign簽字 this note?" he said to Mum. The note showed that he had been talking in class.
Ted hardly gets top scores in his school work. The best he gets is "OK", but often he gets "You can do better than this." Mum knows what it means. She tells me "You can do better than this" means "Extremely bad" in China.
In the USA, teachers never say anything too bad about their students, even if the students are making trouble in class or not working hard enough. The worst they might say is "Please be nicer tomorrow". Many parents are satisfied with對---滿意 a B-grade for each subject.
But things in Chinese schools are quite different. Parents have high expectations for their children. I sometimes felt that my second-grade cousin spent more time on homework than I did when I was a 6th grader in the USA! Yet his parents and teachers didn't think he worked hard enough.

Don’t argue with your parents. Don’t try to talk about something to your parents when you are angry. Your parents probably won’t listen to you if you are shouting at them.

Try to understand your parents. Your parents may think differently from you. Tell your parents what you think, what you care about and why. Perhaps you and your parents disagree on something. Put yourself in their shoes and you may find a better way out.

下面是一些網(wǎng)友發(fā)表的帖子。請認真閱讀，完成下面的信息表。請將答案填寫在答卷相應的位置上。
Recent years , with the development of the computer and the Internet, many students often use computers to surf the Internet . Should students be allowed to surf the Internet? Here are some people’s opinions .
 Tracy
I study in a junior high school . I think students shouldn’t be allowed to surf the Internet . Surfing the Internet wastes a lot of time , so the students spend less time doing their homework . Also many students lose themselves in playing the computer games . In their minds , games are everything and they keep on playing the games for hours . That’s too bad for their study and their health .
Jimmy
  I don’t agree with Tracy . In my opinion , surfing the Internet can help us a lot . For example , I often get help from the Internet . I’m weak in learning English . When I have trouble in learning English, I can get on line to ask for help . Always I can get the answers soon . In this way , I have made great progress .Thanks to the Internet .
 Jeff
   Yes , I have the same opinion as Jimmy . My son , Bob studies very hard . After hours of working hard , he usually feels tired . If he goes on with his study , he will feel stressed out . So I often ask him to surf the Internet to listen to some light music . It can help him relax and he will study better later on .
