Ever since man began to use the telephone, there have been new problems arising from the carrying of messages. At first, each message was carried by a pair of overhead wires. As a result, telephone exchanges were soon surrounded by thousands of wires. The wires were then replaced by cables (电缆)，each containing many pairs of wires. Each cable is capable of carrying many messages. These cables, laid underground, replaced the overhead wires.
The more extensive telephone services have become, the more demand for these services has increased, particularly the demand for long-distance services. In China, for example, this growth is now over 30% every year. Long-distance telephone exchanges are usually in crowded cities, where is not easy to lay new labels for expanding services.
The use of radio to send telephone message and to link all telephone exchanges makes it possible to get rid of overhead wires and some underground cables.
Now man has invented the microwave system ( 微波系统 ). In a microwave system messages from various places can be brought together, and then they are sent out and received by radio. After that, the messages are split into their original form. Finally, they are sent to the places where they are going to be sent.

There is very simple way of measuring the height of a water-tower, which we cannot measure by climbing.
Suppose, for example, that we wish to find out the height of the water-tower, AB, in a factory. We first of all go to where the water-tower is standing and measure a distance of, say, 25 feet from it. Then we take a stick, and stand it in the ground at the spot we have just marked.
Let us suppose the stick we are using is 4 feet in height. We now walk farther away from the water –tower in the same straight line as when we measured off the distance of 25 feet. We go from the water-tower until we come to point E, where with our head on the ground, we see the top of the stick and the top of the water-tower in the same height line---that is, the top of the stick just covers the highest part of the water-tower. Every schoolboy can work out the height of the water-tower now.
Suppose that the line CE is five feet. We know that the stick is 4 feet high and the distance BE is 30 feet. Thus, 5 is to 4 as 30 is to AB.
1.If we want to know how high a tall tree is,_______.
A. we have to climb up the tree
B. we have no way out
C. we must cut down the tree
D we needn’t climb up the tree

3.It is clear from this that the problem can be settled by _________.

4.To measure a water-tower in this way, _________.
A. no tool is needed
B. Besides a stick, tape-measure (卷尺) or at least a ruler is necessary.
C. we have to use nothing but a stick
D. we have to prepare a set of expensive tools
When John Weston awoke that morning, he remembered that his mother was going into hospital. He hadn’t worked out quite what was wrong with her. He knew, though that she hadn’t been well for some time now, and it had become almost familiar to him to see her eyes narrowed in a sudden attack of pain, and her hand pressing against her heart. Their own doctor, who she had finally gone to for advice, had sent her to an expert who knew all about these things. He had told her that just as soon as there was a bed for her, she would have to come into his hospital where he could look after her himself.
During the weeks since then the pains had come even more frequently, and the narrowed eyes became an almost permanent part of her expression. Always rather sharp, she began losing her temper over little things so that John’s father kept his thoughts to himself more and more. John, as ready as possible to make allowances, tried to think what it would be like to have toothache all the time and how bad-tempered that would make you.
So his mother would go into hospital for a few days. He was going to stay with his Aunt Daisy till she came back, and his father would stay on at home by himself. John’s cousin, Mona, was to come in and make the bed and wash the pots and dust round now and again. That was the arrangement, and John didn’t care much for it. Apart from missing his mother(and he was glad she was going away because they would make her better), he wasn’t very fond of his Aunt Daisy because she was even more bad-tempered than his mother.
