三、阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。
What will our world be like if there are no insects? It might sound nice in the 1. beginning (begin). There would be no bugs or flies in your room. But in fact, this could cause really serious 2. problems (problem).
The bad news is that 3. the number of insects keeps 4. dropping (drop) these years. Scientists say it's 5. mainly (main) because of the use of pesticides(农药). They destroy the places that insects live in.
What would happen 6. if all insects are extinct? It's almost impossible to predict (预测), but the results would be terrible. We need insects to pollinate(给……授粉) crops. They also break down dead plants and animals and turn them into new useful things. We need them to keep the soil healthy. 7. Without insects, many animals would have nothing to eat. They would go hungry and die.
The first thing we need to do is let more people understand the 8. importance (important) of the natural world, both for what it does for us and for 9. itself (it). The best place to start is with our 10. children (child). We should teach them environmental awareness(环保意识) at an early age.

答案： 1. beginning 2. problems 3. the 4. dropping 5. mainly 6. if 7. Without 8. importance 9. itself 10. children
