From the pictures, the scientists can often say 40 the weather will change.Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare them with earlier 41 . Perhaps they may find that the clouds have changed during the last few hours. This may mean that the 42 on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.So the weather satellites are a great 43 to the meteorologists. 44 __satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may 45 forecast the weather for a week or more ahead（提前）.36.________________A. help B. to help C. helped D. helping

问答题Passage 2 Broadly 1 , the Englishman is a quiet, shy, reserved person who is fully relaxed only among people he knows 2 . In the presence of strangers or foreigners he often seems inhibited, 3 embarrassed. You have only to witness a commuter train any morning or evening to see the truth of this. Serious-looking businessmen and women sit 4 their newspapers or dozing in a corner: 5 one speaks. Obviously, there is here an unwritten but clearly understood code of behavior 6 , if broken, makes the person immediately the object of suspicion. It is a well-known fact that the English have a passion 7 the discussion of their weather and that, given half a chance, they will talk about it at 8 . Some people argue that it is because English weather defies forecast and hence is a source of interest and speculation to everyone. This may be so. Certainly Englishmen cannot have much faith in the 9 , who, after promising fine, sunny weather for the following day, are often proved 10 when a cloud over the Atlantic brings rainy weather to all districts! The man in the street seems to be as accurate -- or as inaccurate -- as the weathermen in his predictions. The overseas visitors may be excused for showing surprise at the number of references to weather that the English 11 to each other in the course of a single day. Very often conversational greetings are replaced by comments 12 the weather. “Nice day, isn’t it? Beautiful!” may well be heard instead of “Good morning, how are you?” Although the foreigner may consider this exaggerated and comic, it is worthwhile pointing out that it could be used 13 his advantage. If he wants to start a conversation with an Englishman but is 14 a loss to know where to begin, he could do well to mention the state of the weather. It is a safe 15 which wills provoke an answer from even the most reserved of Englishmen.
