It is ten o'clock at night and you are outside. You can see many stars in the sky. Each star is another sun. The sky is big, and it hag many suns.
Our sun is near to us. It warms us and gives us light in daytime. The stars are not near. We can see their light only at night, and they do not warm us.
The stars are not all the same. Many stars are quite like our sun. They are the same size, and they have the same colour, yellow. Other stars are bigger or smaller. A “giant(巨人)” star is very, very big. A “dwarf(侏儒)”is a small star—smaller than the sun.
Stars have different colours, too. They can be blue, orange, yellow, white or red. There are giants and dwarfs in all these colours. All stars are, of course, very hot. The hottest stars are the blue ones. White stars come next, they are less hot. Then yellow and orange stars are less hot again. Red stars are the least hot, and they are also the oldest stars.
Light moves very quickly across the sky, eighteen million (18,000,000)kilometers in a minute. Our nearest star is a red dwarf. Its name is Proxima Centauri ( proxima ＝ nearest), and it gives a weak, red light. We can just see this light. It left Proxima Centauri 4.25 years ago, and now tonight, it is reaching cur eyes. Think about it! In one minute, 18,000,000 kilometres. So, in 4.25 years—well, how many kilometers? You can find the answer yourself.
I will just say this: Proxima Centauri is a long way from us.
1．According to the temperatures on stars, the right order from the lowest temperature to the highest is ________.
[ ]
A．red→yellow→white→blue
B．orange→red→blue→white
C．blue→white→yellow→red
D．white→blue→orange→red
2．All the following am right except ________.
[ ]
A．a “dwarf” is smaller than the sun
B．there are dwarfs in different colours
C．a “dwarf” is a small star
D．dwarfs are the least hot
3．How far away is the star Proxima Centauri from us?
[ ]
A．40,208,400,000,000 kilometres.
B．9,460,800,000,000 kilometres.
C．679,140,000,000 kilometres .
D．279,225,000,000 kilometres .
4．When we say “The star Procyon is ‘ten light years’ away.”, we mean ________.
[ ]
A．we can reach the star in ten years
B．we first saw the star ten years ago
C．the light left Procyon ten years ago
D．Procyon has been that far away for ten years

Trees should only be pruned（修剪）when there is a good and clear reason fordoing so and, fortunately, the number of such reasons is small．Pruning involves the cutting away of overgrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way.
First, pruning may be done to make sure that trees have a desired shape or size．The object may be to get a tree of the right height, and at the same time to help the growth of small side branches which will thicken its appearance or give it a special shape．Secondly, pruning may be done to make the tree healthier．You may cur out diseased or dead wood, or branches that are rubbing against each other and thus causing wounds．The health of a tree may be encouraged by removing the branches that are locking up the centre and so preventing the free movement of air.
One result of pruning is that an open would is left on the tree and this provides an easy entry for diseases, but it is a wound that will heal（愈合）．Often there is a race between the healing and the disease as to whether the tree will live or die, or that there is a period when the tree is at risk．It should be the aim of every gardener to reduce the risk as far as possible．It is essential to make the area which has been pruned smooth and clean, for healing will be slowed down by roughness．You should allow the cut surface to dry for a few hours and then paint it with one of the substances available from garden shops produced especially for this purpose．Pruning is usually done in winter, for then you can see the shape of the tree clearly without the interference（妨礙）from the leaves and it is, too, very unlikely that the cuts you make will bleed．If this does happen, it is, of course, impossible to paint them properly.
1．Why should pruning be done?
A．To make the tree grow taller. B．To improve the shape of the tree.
C．To get rid of the small branches. D．To make the small branches thicker.
2．Trees become unhealthy if the gardener .
A．helps a wound to dry.
B．covers a rough surface.
C．damages some of the small side branches
D．allows too many branches to grow in the middle
3．Why is a special material painted on the tree?
A．To help a wound to dry. B．To cover a rough surface.
C．To make a wound smooth. D．To prevent disease entering a wound.
4．A good gardener prunes a tree .
A．several times throughout the year B．as quickly as possible
C．occasionally when necessary D．regularly every winter
5．What was the author’s purpose when writing this passage?
A．To discuss different methods of pruning.
B．To introduce some common knowledge of pruning.
C．To explain how trees develop disease.
D．To give practical instruction for pruning a tree.
