Ⅲ. 【语篇解读】本文主要讲述人们为了减少汽车尾气污染,建议人们骑自行车上班,并提议开辟自行车道。
1. B 解析:由于选项在本句中作谓语而谓语应为动词,故排除A、C两项。ride bikes to work骑自行车去上班。
2. A 解析:本句的if从句提示如果有更多的人骑自行车去上班的话,那么就会减少汽车的数量以及对空气的污染。car是可数名词,故选能修饰可数名词的few的比较级。
3. B 解析:考查have … for 表示“有为自行车而专设的特殊道路”。for在这里表示的。
4. A 解析:本句中有否定词no, 而yet多用于现在完成时的否定句和疑问句中。
5. D 解析:根据上下文看此处的含义是“并不是每个人都认为这是个好主意”。分析选项,只有idea符合题意。
6. D 解析:either用于否定句末,表示“也”的含义;also也表示“也”之意,但用于肯定句中。
7. C 解析:考查too … to … 结构,表示“太……而不能……”。
8. B 解析:根据上下文此处应填something“有些事情”,用于肯定句;anything“任何东西”,用于否定句和疑问句;nothing“没有什么”,表示否定。
9. A 解析:be closed to表示“对……关闭”,而be open to表示“对……开放”。由Something has been done about it. 可看出,此处应是禁止汽车入内的,所以选择A项。
