【巩固】
1、Every minute is made full use of _______ our lessons. A．studying B．to study C．study
D．being studied
【答案】B
【解析】此题容易误选A，认为动名词作介词的宾语。其实此题应选B，此句是被动句，转换成主动句就成为 we make full use of every minute to study our lessons.。这是不定式作目的状语。
2、—Did the book give the information you needed? —Yes, But _______ it, I had to read the entire book. A．to find
B．find D．finding
C．to be finding 【答案】A
【解析】答语句意为：是的，但是为了找到它，我不得不阅读了整本书。表示目的要用动词不定式形式。由于不表示正在进行，故不用进行时态。
3、I feel greatly honored _______ into their society. A.to welcome 【答案】C
【解析】welcome与“I”之间为逻辑上的动宾关系，故welcome须用被动语态形式。该句语意相当于I feel it a great honor to be welcomed into their society.。
B.welcoming
C.to be welcomed
D.welcomed
4、The crowd cheered wildly at the sight of Liu Xiang, who was reported _______ the world record in the 110-meter hurdle race. A．breaking
B．having broken D．to break
C．to have broken 【答案】C
【解析】sb./sth.is reported to do sth.为常用的表达方式，to do不能用doing形式，“打破世界记录”是已经发生的事情，故用不定式的完成式。
