Bamboo is one of the nature’s most surprising plants. Many people call this plant a tree, but it is a kind of grass.
Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist recorded one bamboo plant that grew almost 1.5 meters in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1,000 kinds of bamboo that grow around the world on both mountains and plains(平原).
Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimeters across. This plant also comes in different colors, from yellow to black to green.
Many Asian countries have been using bamboo for hundreds of years. They often use bamboo for building new buildings. As a matter of fact, the cables(绳索) that hold up the hanging bridge across the Min River in Sichuan are made of bamboo. The bridge has been in use for more than 1,000 years, and is still holding strong.
In Africa, engineers are teaching poor farmers how to find water using bamboo. These African countries need cheap ways to find water because they have no money, and their fields often die from no rain and no water. It seems that bamboo is one of the best things they can use. Bamboo pipes and drills(钻) can help to make the poor thirsty fields to be watered.

【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。
5. D。第2段的倒数第2句中说except Europe,由此可知答案为D。
