Scientists are very interested in the Universe,and they always want to know more about it. Years ago they knew many things about the moon. They knew how big it is and how far away it is from the earth. But they wanted to know more about it. They thought the best way was to send men to the moon. The moon is about 384,000 kilometers away from the earth. A plane cannot fly to the moon because the air reaches only 240 kilometers away from the earth. But something can fly even when there is no air. That is a rocket(火箭)
How does a rocket fly? There is gas(气体) in the rocket. When the gas is made very hot inside the rocket, it will rush out of the end of the rocket, so it can make the rocket fly up into the sky. Rockets can fly out into space. Rockets with men in them have been to the moon. Several rockets without men in them have flown to another planet(行星) much farther away than the moon. One day, rockets may be able to go to any place in space.

A: how far B: how big C: how old D: both A and B

Children start out as natural scientists. They are interested in looking into the world around them. Helping them enjoy science can be easy—there’s no need for a lot of expensive lab equipment. You only have to share your children’s curiosity(好奇心).
First,______1._________ I once visited a second-grade classroom to talk about working as a scientist. The children asked me “textbook questions”—about schooling, salary, whether I liked any job. When I finished answering, I said: “Do you have questions of your own—about science”
After a long time, a boy put up his hand. “Am I just a bag of blood? Whenever I cut myself, I see blood.” This began a lot of questions that lasted nearly two hours.
Second, ________2.________ Studies have shown that after asking a question, adults usually wait only one second or less for an answer—no time for a child to think. When adults increase their “wait time” to three seconds or more, children can give more logical(逻辑的), complete and creative answers.
Third, _____3.__________ Once you have a child telling his idea in a science discussion, don’t jump in with “That’s right” or “Very good.” These words work well when it comes to encouraging good behavior. But in talking about science, quick praise can mean that the discussion is over. Instead, you can say “That’s interesting” or “I’d never thought of it that way before,” or come up with more questions or ideas.
__________4.__________ It doesn’t make sense—children are always thinking, without your telling them to. What’s more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so he won’t have his own idea.
Last, _______5.________ Real-life feelings of nature are far more exciting than any lesson children can learn from a book or a TV program. Let children look at their fingertips through a magnifying glass(放大镜),and they’ll understand why you want them to wash before dinner.
Doing this and they will clearly see that learning is not something that happens only in school. Learning is something to be enjoyed every day—for a lifetime.
A.Never push a child to “Think!”. B.show, don’t tell. C.give them time to think D.listen to their questions E.watch your language |

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.
1.Radio telescopes help collect ____________ from the universe
A.light B.objects C.radio waves D.visible signals
2.Most antennas of radio telescopes are made in the shape of a dish to ____________.
A.make the antennas strong enough
B.increase the number of radio waves
C.turn radio waves into electronic signals
D.focus radio waves on the sub-reflector
3.The underlined word "interferences" in the passage refers to __________________.
A.the noises made by villagers and animals
B.the sounds from the radios and televisions
C.the people who go to Guizhou to watch FAST work
D.the radio waves and electronic signals from humans
4.What have we done with the help of radio telescopes?
A.We have received pictures of deep space.
B.We have discovered unknown lives in the universe.
C.We have found some unknown objects in the universe.
D.We have turned the radio waves from space into light.
