Blood is made up of different parts, such as red blood cells(红细胞), 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 molecules “B”. According to which an how many molecules are on the red cell, scientists divide blood into four types: A, B, AB, O. Scientists have been wondering if there are some links between people’s blood

types 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. People with type A: They look peaceful from the outside. But they ask too much of

themselves so 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
