All the oceans of the world will be dead in the future unless action is taken at once. How can this happen?

We have already seen that people allow all sorts of waste products to flow into the sea. It is almost impossible to measure how much waste water and industrial waste in our oceans, but we can find out how much oil is poured into them legally and illegally. It is illegal to pour oil into the sea close to the shore, but when a ship is many miles out to sea, there are no such rules. Scientists have different ideas as to the amount of oil putting into the sea, but the lowest figure for oil poured in European waters alone is nearly 200 000 tons every year. Some people say the figure could be ten times as high.

It is not only our coasts that suffer from oil pollution. Many shell fish, for example, now have high amounts of poisonous substances(物质). Next time you have shell fish to eat, how can you be sure that they are free from oil pollution? You cannot see the effects and you cannot taste them, either. It is really quite a problem.

51. This passage is mainly about_________________.

A. pollution in the oceans                          B. oil pollution in the waters

You have been badly injured in a car accident. It is necessary to give you a blood transfusion because you lost a great deal of blood in the accident. However, special care must be taken in selecting new blood for you. If the blood is too different from your own, the transfusion could kill you.
There are four basic types of blood; A, B, AB, and O. A simple test can make sure of a person's blood type. Everybody is born with one of these four types of blood. Blood type, like hair color and height, is received from parents.
The four groups must be transfused carefully. A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. O can give to any other group; therefore, it is often called the universal donor (万能捐赠者). For the opposite reason, AB is sometimes called the universal recipient(接受者). However, because so many reactions (反应) can happen in transfusions(输血), patients usually receive only salt of plasma (liquid part of blood) until their blood can be matched as exactly as possible in the blood bank of a hospital. In this way, it is possible to prevent the transfusion from any bad reactions.
