1．We have always been warned of the dangers of the forest fires. They cause     1    to a forest. They kill many plants and animals in an eco-system, which is a group of living things and their environment. But have you ever heard of a forest fire that can be     2     for a forest?

2．People start some of the fires with special reasons to actually do well to the eco-system.

3．In fact, fires are a natural part of any eco-system. Without fires, the oldest and largest trees would stop sunlight from reaching the forest floor. Fires can       3       some of these old trees. When the trees die, they provide something good for the earth. New trees can grow strong and healthy in their place.

4．Some trees even need fires to grow. These trees hold their seeds(種子) inside. Heats from a fire allow the coat of the seeds to open up. Then the seeds fall to the ground and have the 4 to grow.

5．Scientists, who know about nature’s needs, start some of these fires, called controlled burns. A fire is started and kept under control. This way, the fire does not spread out of the area or 5    a large space of the forest. Fires can be dangerous for animals. Even when animals continue to live after forest fires, they can go hungry   6     their food has been damaged in the fire. Small, controlled fires mean that animals will not have to move far to find food. After some time, small plants begin to grow. Animals return soon after the plants return. This   7  makes an eco-system.

6．So the next time you hear about a forest fire, think about the good as well as the bad. It may take a new eco-system a while to return, but it will likely come back stronger and healthier than ever.

【解析】

1.They cause       to a forest. They kill many plants and animals in an eco-system.因為森林火災(zāi)殺死生態(tài)系統(tǒng)中的許許多多動物和植物，所以他們會引起毀滅性破壞。答案是cause damage。

2.But have you ever heard of a forest fire that can be      for a forest? People start some of the fires with a special reasons to actually do good to the eco-system.第一段講森林火災(zāi)的危害，然后用but表示轉(zhuǎn)折，另外第二段講述do good to the eco-system森林火災(zāi)對生態(tài)系統(tǒng)帶來的好處，所以選helpful有幫助的。

3.Without fires, the oldest and largest trees would stop sunlight from reaching the forest floor. Fires can       some of these old trees. When the trees die, they provide something good for the earth.第三段講述了“沒有林火，那么古老而高大的樹會阻擋陽光，而林火恰恰能減少或者說弄掉這樣的一些樹，后面有講這些樹死了之后能為土壤提供營養(yǎng)。所以答案選get rid of除掉、擺脫

4.Then the seeds fall to the ground and have the    to grow. 第四段講述了“有些樹需要林火的幫助而生長，種子在火的熱量的作用下破殼而出，然后這些種子才有生長的機(jī)會”。所以答案選chance。

5.This way, the fire does not spread out of the area or    a large space of the forest. 第五段講述了“控制性燃燒的林火不會超越控制區(qū)域或占據(jù)很大的空間”，而新世紀(jì)英語中有這樣的詞組“cover an area of…占地面積…… ”，所以選cover。

6.They can go hungry        their food has been damaged in the fire.這題比較簡單，因為食物在林火中遭受破壞，所以動物們要挨餓。所以選because。

7.After some time, small plants begin to grow. Animals return soon after the plants return. This     makes an eco-system.第五段最后講述了“過了一段時間之后，在小的植物‘在春風(fēng)吹又生’之后小動物也開始生長了的又一個生態(tài)系統(tǒng)開始了”，所以選答案again。
