请做以下类似试题：
(1) Who do you think you’d like _____ with you, a boy or a girl?
A. to have go B. to have to go
C. to have gone D. having to go
在确定答案之前，我们先来看看下面这个句子：
I think I’d like to have a boy go with me.
句中的 go 要用原形，这是因为其前有表示使役的动词have。在此句中，假若对名词a boy 提问，便可得出：
Who do you think you’d like to have go with you?
对照上面一题，答案很显然是A。
(2) Who did the boss _____ his car this time?
A. make wash B. make to wash
C. make washing D. making to wash
在做此题之前，也请先看看下面这个句子：
The boss made Jack wash his car this time.
假若对句中的名词Jack 提问，便可得出：
Who did the boss make wash his car this time?
由此可知上面题答案为A。(www.hxen.com)
(3) You can never imagine what great difficulty I had ______ your house all by myself.

14. How happy we are! The holiday we have been looking forward _______ at last.
A. to has come B. to have come
C. to having come D. has come
【陷阱】几个干扰项均有可能误选。
【分析】其实正确答案是A。大家知道，短语 look forward to意为“盼望”，其中的 to 是介词，而不是不定式符号，所以后接动词要用动名词，许多同学据此便选择了C。但问题是，句中介词 to 的宾语不是have come，而是the holiday。正解的句子分析是：the holiday为句子主语，we have been looking forward to 是修饰主语的定语从句(介词 to 的宾语是引导该定语从句的关系代词 that，被省略)，has come 是句子谓语。请做以下类似试题：
(1) The man you referred to _____ just now.
A. comes B. come
C. coming D. came
答案选D，句子主语为 the man，you referred to 为修饰 the man 的定语从句，空白处填 came，为句子谓语。
(2) The theory he sticks to ______ to be of no use in our studies.
A. proves B. prove
C. proving D. be proved
答案选A，he sticks to 是修饰主语 the theory 的定语从句，句子的基本结构为 The theory proves to be of no use in our studies.
(3) The work he devoted his time to _____ worth praising.
A. was B. be
C. being D. been
答案选A，he devoted his time to 是修饰主语 the work 的定语从句。句子的基本结构为 The work was worth praising.
(4) I think this is the very work that we must finish ____ her.
A. to help B. help
C. helping D. helped
答案是 A。句中空格处填的动词help 并不是 finish 的宾语，正确的句子分析是：that I must finish 是修饰名词 the very work 的定语从句，finish 的宾语是引导该定语从句的关系代词 that，其后的不定式 to help her 是目的状语。
