In today's world, almost everyone knows air pollution and water pollution. But not all people know that noise is also a kind of pollution. In fact, noise pollution is harmful(有害的) to human health, too.
People usually have poorer hearing if they work under noisy conditions. Recently many teenagers in America can hear no better than 65yearold people, for these people like to listen to pop music, and most of the music is a kind of noise. Many people living near airports become deaf.Noise produced(产生) by jetplanes(喷气式飞机) or machines will make people's life difficult and unpleasant, or even make people ill, or even drive them mad.

2．A 第一个empty用作动词，表示“倒空”； 第二个empty作形容词，表示“空的”，故选A。
3．A
4．D 考查含情态动词的被动语态。其结构为：情态动词＋be＋动词的过去分词。
5．B 考查介词的用法。句意：“你的毛衣看起来(很)漂亮。它是羊毛制的吗？”“是的，在上海制造的。”be made of和be made from都表示“由……制成”，be made of指能看出原材料，be made from指看不出原材料。ba made in意为“在……制造”，后接地点。故选B。
