The world is not hungry, but it is thirsty. It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why? Because about 97% of water on the earth is sea water which we can't drink or use for watering plants directly. Man can only drink and use the 3%--- the water that comes from rivers and lakes. And we can't even use all of that, because some of it has been polluted. Now more water is needed. The problem is: Can we avoid a serious water shortage later on? First we should all learn how to save water. Secondly, we should find out the ways to _ it. Scientists have always been making studies in the field. Today, in most large cities water is used only once and then runs to the sea or rivers. But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next? The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it's already used in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we'll be in no danger of drying up. ,,. The world is thirsty because _ . A) 3/4 of the earth is covered with water B) we have enough sea water to use directly C) we haven't used all the water in rivers and lakes D) About 97% of water on the earth can't be drunk or used for watering plants directly

Many hospitals have blood banks. In these banks, blood of all types is stored. When blood is needed, it is taken from the bank. Healthy people then give blood to the bank to replace the blood that is used. Blood can be kept in the fridge for about three weeks with a kind of chemical. When people lose much of their blood because of operations or accidents, they may need transfusions . Some people may need transfusions because of illness. Sometimes only a part of the blood is used for transfusions. Plasma , the liquid part of the blood , may be given alone. Transfusions of plasma are often given when people have been badly burned. When a person gets a transfusion, he gets blood of the same type as his. Or there may be a bad reaction . To make it safer, before a transfusion is given, the blood to be used must be tested with the blood of the person who is to receive it. This testing is called cross matching of the blood. Oswald Robertson, an American doctor, was the first one to give transfusions. He used blood that had been stored for some time to help wounded soldiers in 1918 in World War One. Blood banks usually have _ . A) only one type of blood B) one or two types of blood C) two or three types of blood D) all types of blood
