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.

When I left school five years ago, I said to myself, “That’s that! No more learning for me．Now I can enjoy myself in the evening．” But about a year ago the boss said, “We’re going to get a computer in the near future．” What does he mean? I simply don’t know．Anyway, I decided to go to evening classes．I’m quite an expert(专家) on computers now and you know, I actually enjoy studying．
Eve
I haven’t much interest in studying．To be honest, I don’t like reading very much, except for magazines and that sort of thing．Just reading, that is, to kill the time．But I do enjoy watching TV．Not that I watch everything．In fact, I choose my programmes very carefully．I’m particularly interested in current affairs(时事)．In some ways I think I learn more in this way than I did at school．
Ted
I’m a very different sort of person-I simply love doing things．That’s why I enjoy sports so much．I mean, actually playing．I hardly ever watch it on TV, but I do read quite a bit about it．I’m even interested in the history of sports．I don’t have much time for anything else, except that I quite like dancing．Some people say I’m not very good at it, though．
Joan
I should say I have great interest in studying．I’d rather do this than anything else．Since I left school．I’ve taken courses in all sorts of things．I go to the city library once a week, but I much prefer evening classes because it’s more fun that way．My latest “craze（狂热）”-if you can call it that -is foreign languages．I’m learning two, not one!
