诸多疑问
同学们，天天练（3）的解析今天终于上线了，让大家久等了！
第三组练习题解析
21. It’s our duty to ______ people ________ too many trees.
A. stop; cutting down B. prevent；to cut down
C. keep; cutting down D. make; cut down
答案：A
译文： 阻止人们砍伐更多的树木是我们的责任
解析：句中it 是形式主语。to stop sb. from doing sth. 意为：阻止某人做某事。本句省略了介词from。 故选cutting down
22.----Will you please show me how to do the role play exercise?
----Sure. Now let me tell you _____ first.
A. which to do B. how to do C. when to do D. what to do
答案：D
译文：请你告诉我如何做角色扮演好吗？当然可以，现在我就告诉你第一步做什么。
解析：how to do 和 what to do 一直是学生比较混淆的语法点。其实how to do 表达的是怎样做某事，其do 的后面要有宾语。如： how to do the role play. 而what to do 表达的是做什么？do 后面的宾语就是 what。原句中“角色表演是有多项步骤的” 那第一步是什么并没有告诉我们，所以要用what to do first。
23. Is this factory ______ some foreign friends visited last Friday?
A. that B. where C. which D. the one
答案：D
译文：这是那个上星期五一些外国朋友参观过的工厂吗？
解析：这是一个定语从句考点。难点设在使用了一般疑问句。处理这种疑难的办法是将疑问句变成陈述句。变过之后发现没有先行词，故增加the one 补充上先行词。
24. Is this the factory _____ he worked ten years ago?
A. that B. where C. which D. the one
答案：B
译文：这是他爸爸十年前工作过的工厂吗？

A when B before C after D since
