Is human blood all the same? “Yes，” you may say．“It's all red．”

Well，it's not as simple as you might think．

Blood is made up of different parts，such as red blood cells，white blood cells，and platelets（血小板）．

Two chemical molecules（分子）on the red blood cells make people's blood different．Scientists mark one molecule "A" and the other molecule "B".

According to which and how many molecules are on the red cell, scientists divide blood into four types: A, B, AB and O.

Your blood type will stay the same your whole life.

Scientists have been wondering if there are some links between people's blood type and their personalities but they don't know for sure yet.

  But some say that people with the same blood type may have things in common.

What's your blood type? Do you have family members or friends who are the same type as you? Read the following. Are you like this?

People with type A: They look peaceful from the outside. But they ask too much of themselves that they may be very nervous inside. They get happy or sad easily. Sometimes they are shy but always very careful. They can easily win people's trust.

People with type B: They have strong minds. Once they start a task, they don't give up easily. They'll try their best to finish it and do it well. Type B people always try to make themselves different from others. They want to do things in their own way in life.

People with type AB: They are maybe the strangest among all blood types. They can be both open and shy, noisy and quiet at the same time! They are responsible （负责的） and always ready to help others.

People with type O: They're open and good at making friends. They always start tasks but don't always finish them. They have lots of new ideas and love to be the centre of attention. They always strongly believe in themselves.

“If he doesn’t call me, I’m going to die!”

That’s a pretty normal feeling. It means you are “in love” ---kind of. It’s puppy love (早恋、初恋)，not real love--- not true love, yet.

Puppy love is common among students all over the world. In the West, people think puppy love is a healthy part of a teenager’s life. 1.In China, parents and teachers think it is a problem.

Puppy love is beautiful. It’s cool to love someone, or be loved by someone else instead of your mother or your dog. It can make you a better person. 2.You will know how to use your love to help other people.

If you find yourself “in love”, it’s OK, but …wait! 3.现在你有许多重要的事情要做。Think of these questions: Will you still love him or her ten years later? Do you have enough education to find a good job and live a happy life with the person you love in the future? What would you do if you found someone better than him or her? I bet (打赌) you are not sure of these answers. Why? 4. 因为你太小还不懂真爱。

5.True love will come when you grow up. Now, you should try to be the best person you can be, and do the very best you can. That means doing well at school and being a good son or daughter first.

It is said that more than four million people die each year from smoking. That number is ncreasing. Seven in ten of those deaths are in developing countries. These numbers are frightening.

    Yet people around the world continue to smoke. In the United States, about forty-seven million adults smoke. This year, more than 430,000 Americans died of diseases which have something to do with smoking. The American Cancer Society says smoking harms the body greatly. It warns that smoking even a small number of cigarettes is dangerous.

    It is not easy to give up smoking. However, doctors say you probably will live longer if you do stop smoking. You will feel better and look better. You also will protect the health of family members who breathe your smoke.

    The American Cancer Society says there is not one right way to stop smoking. They say any way that helps is worth trying. People can take long walks or spend time in places where smoking is not allowed. Also, they can eat a small piece of fruit or vegetable when they want to have a cigarette. The American Cancer Society says the sooner smokers stop smoking, the more they will reduce their chances of getting cancer and other diseases.
