【答案与解析】这是一篇关于竹子的说明文。讲述了竹子的生长处、种类、颜色、用途等。
1. C。由第2段的第1句我们可以推测出竹子与其他草类相似的地方是grow back very quickly。
2. C。阅读第3段的第2句They may only grow to be a few centimeters wide while others may grow to more than 30 centimeters across可推知：while(表对比，意为“而”)前面讲有些竹子(bamboo)很细，只有(only)几厘米粗，而与相比，while 后面则讲有些竹子长得很壮，可以有30厘米粗。因此答案选C。
3. B。由第2个题目我们可知竹子一天能长1.5米，那么三天就能长4.5米。
4. A。根据第5段第2句Because they have no money可知要选用bamboo。 www.kgf8.com

Can trees talk? Yes—but not in words. Scientists have reasons to believe that trees do communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree(柳树) attacked in the woods by caterpillars(毛毛虫) changed the chemistry of its leaves and made them taste so terrible that the caterpillars got tired of the leaves and stopped eating them. The even more astonishing, the tree sent out a special vapour — a signal causing its neighbours to change the chemistry of their own leaves and make them less tasty.
Communication, of course, doesn’t need to be always in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar(花蜜) for honey. So why shouldn’t trees have ways of sending messages?
1. From the passage we know that caterpillars _______.
A. like willow trees B. enjoy eating fallen leaves

Do you know Australia? Australia is the largest island in the world. It is a little smaller than China. It is in the south of the earth. Australia is big, but its population is not large. The population of Australia is nearly as large as that of Shanghai.
The government has made enough laws to fight pollution. The cities in Australia have got little air or water pollution. The sky is blue and the water is clean. You can clearly see fish swimming in the rivers. Plants grow very well.
Last month we visited Perth, the biggest city in Western Australia, and went to a wild flowers’ exhibition. There we saw a large number of wild flowers we had never seen before. We had a wonderful time. Perth is famous for its beautiful wild flowers. In spring every year Perth has the wild flowers’ exhibition. After visiting Perth, we spent the day in the countryside. We sat down and had a rest near a path at the foot of a hill. It was quiet and we enjoyed ourselves. Suddenly we heard bells ringing at the top of the hill. What we saw made us pick up all our things and run back to the car as quickly as we could. There were about three hundred sheep coming towards us down the path.
