Ⅵ、阅读理解
The old believe that the universe never changes, but it is quite wrong. Even before the invention of the telescope(望远镜), Astronomers noticed that bright stars suddenly appeared in the sky and then later disappeared. Astronomers called these stars "novae(新星)" because they thought they were new. In fact we now know that they are really old stars and they are slowly dying.
Novae are old stars which are slowly dying. As they do so, they let out large clouds of material(物质), sometimes as large as the earth, and these fly into space very quickly, about 8,000,000 kilometers an hour. When this happens, we can see the hotter parts of the star, and this is why novae are so bright. To us, the explosions are so large, but they only use a small part of the dying star's energy(能量). The death is a slow one and the star may continue to explode(爆发) for thousands of years. In fact, there are even some stars which explode once every two weeks.
There are other old stars which do not die slowly, but are completely destroyed(毁坏) by one great explosion.
These are known as "supernovae". The explosion of a supernovae is as much as about a million, million, million, million hydrogen bombs() going off at the same time. Just before the explosion the star's density(密度) becomes very great. A matchbox of materials taken from the star at that time would weigh about 1,000 tons and the star would be turning at about 16,000,000 kilometers an hour. The explosion itself happens suddenly, but the supernovae continues to shine long after the explosion.
Chinese astronomers discovered one supernovae in 1054, but we still can see it today. It has been shining for at least nine hundred years.
( ) 1. Long ago astronomers thought novae were _____.
A. stars that disappear suddenly B. stars that explode
C. new stars D. dying stars
( ) 2. Supernovae are different from novae because _____.
A. they are dying stars B. they die gradually
C. they can be seen from the earth D. they explode suddenly
( ) 3. The underlined sentence "As they do so" (line 1, Paragraph 2) means _____.
A. as they let out clouds of material B. as they are slowing dying
C. as they explode into energy D. as they consume the star's energy
( ) 4. The death of a novae is slow because _____.
A. each novae only explodes once every two weeks
B. the explosion may continue for thousands of years
C. each explosion only consumes a little energy of the star
D. the novae may continue to shine long after the explosion
( ) 5. A matchbox of material taken from a supernovae weigh 1 000 tons because _____.
A. the star turns at a very high speed B. the density of the star is very great
C. the star explodes suddenly D. the star gives a lot of material
