Many objects in the universe are invisible,but they send radio waves. The radio telescope thus appeared, and it is considered one of the greatest inventions in the twentieth century. Reber built the world's first radio telescope in 1937. Ryle and Hewish developed radio telescope systems for the location of weak radio sources, and they shared the Nobel Prize for Physics in 1974.

A radio telescope is usually made up of:

One or more antennas to collect the radio waves. Most antennas are made in the shape of a dish to collect and reflect, the radio waves to the sub-reflector, in the same way as a curved mirror focuses visible light to one point.

A receiver and amplifier to receive the radio waves from the sub-reflector, and make these weak radio waves strong enough to be recorded and turned into electronic signals. To make an amplifier sensitive enough, it is usually cooled to, very low temperatures (e. g. as low as -270℃）.

A recorder to keep a record of the electronic signals. Most :radio telescopes today keep the signals to the computer's memory disk for astronomers to analyze later.

Radio wavelengths are much longer than those of visible light, and the radio waves from deep space are always weak. To catch Radio wavelengths are much longer than those of visible light,and the radio waves from deep space are always weak. To catch these waves, radio telescopes usually have huge antennas. The sizes of most antennas in use today are around 50 to 300 metres in diameter. The antenna of FAST in Guizhou, China, the latest and largest radio telescope in the world, is 500 metres in diameter, as large as the size of 30 football fields.

To avoid interferences, and keep the telescopes sensitive, radio telescopes are built in places where there are no human radio waves or electronic signals. For example, FAST is 5 kilometres away from the closest village and 25 kilometres away from the nearest town.

Radio telescopes create pictures of the sky, not in visible light, but in radio waves. This is extremely useful, because there are objects that can't be seen, objects that we wouldn't even know without radio telescopes.

【题目】

What's the most important thing for you to have in your life? Somebody mentions hard work; others suggest knowledge, love and luck.

If you arrange(排列)the 26 English letters in order and use numbers to represent each of them, for example, 1 for a, 2 for b, 3 for c. . . 26 for z, you can change an English word into a number. So hard work becomes 8+1+18+4+23+15+18+11=98，meaning 98 is its mark; knowledge: 11+14+15+23+12+5+4+7+5=96;love:12+15+22+5=54, and luck: 12+21+3+11=47，a small mark. None of these words can give one a full mark. What about money? It can't, either.

Then what else? Don't be worried. You can always find an answer to a problem in your life, when you change your way of looking at things or doing things, or your attitude. Yes, attitude is the word. See for yourself : attitude:1+20+20+9+20+21+4+5=100，a full mark.

Different attitudes lead to different courses of life. Most time people hope for a better life. It is possible that they will have a better life if they change their attitudes. When you change your manner and became friendly toward others, you'll meet more smiling faces toward you. In the same way, if you take a positive attitude toward failure, you'll find it's also rewarding(有益的)though it has caused you losses(损失).

【1】The writer thinks is the most important thing in a person's life.

A. hard workB. knowledge

C. moneyD. attitude

【2】What is the mark of the word. "money" according to the passage?

A. 73.B. 72.C. 75.D. 62.

【3】From the passage we can learn that .

A. different attitudes come from different courses of life

B. sometimes failure can bring you good if you take a positive attitude

C. math can solve every problem easily in our daily life

D. none of the English words except "attitude" is 100 or more
