问题     Insects live in bushes and grass and trees, in fields and houses and in the ground. Some even live on other animals.
    Did you know that there are more insects in the world than any other kind of animal? They fly and hop and crawl and dig. Some insects, the ants, build hills and cities of their own. Insects called silk worms spin silk. Bees make honey. And crickets(蟋蟀) make music with their feet.
    Lots of insects grow up in a curious way. When they are little, they look like tiny worms, and most of their lives are spent in just growing. Mosquitoes(蚊子) start this way, and so do beetles(甲虫) and flies, ants and bees. Some caterpillars (毛虫) grow into butterflies. Other wormlike wriggling (蠕动) things become moths (蛾). So all insects do not look the same. Worms in fruit are insects. So are caterpillars and potato beetles, flies and moths.
    The things that some insects do are helpful to people. They spin silk and make honey and help the flowers to make seeds. Some insects are pests. They bite and sting (叮) and eat our plants and clothes, food and even furniture. Insects are everywhere.
