知识依托：现在分词和不定式都可作结果状语，前者表示的是顺理成章，自然而然的结果；而不定式作结果状语，有两种情况：
①用来表示“意想不到、突然的结果”。
②用于某些结构中，如“too…to…,so…as to…”。
例：He hurried to the station,only to find the train had left.(意想不到的结果)

3.I’ve worked with children before,so I know what________ in my new job.
(NMET 2000)
A.expected B.to expect
C.to be expecting D.expects
命题意图：考查疑问词加不定式的用法。此题属四星级题目。
知识依托：疑问词加不定式可以作主语、表语及用在某些动词后作宾语，相当于名词性从句。这些动词有ask,discuss,decide,explain,forget,find out,know,learn,remember,show, tell,wonder等等。what to expect相当于what I will expect。故答案为B。
答案：B
2.The purpose of new technologies is to make life easier,________ it more difficult.
A.not make B.not to make
C.not making D.do not make
命题意图：考查不定式作表语。此题属四星级题目。
知识依托：句子的表语是两个并列比较的不定式；to do A和to do B两个不定式作比较。后者“to”不可省略。
错解分析：A项干扰性较强，但应掌握to do A和to do B两个不定式作比较，后者to不可省略。
解题方法与技巧：分清句子的基本结构。
1.Robert is said________ abroad,but I don’t know what country he studied in.
A.to have studied B.to study
C.to be studying D.to have been studying
命题意图：考查动词不定式的时态(完成式)的用法。此题属五星级题目。
知识依托：不定式的完成式表示的动作通常在谓语所表示的动作(或状态)前已完成，强调动作发生在过去。
错解分析：C、D项干扰较大。若选C项，but后句子应改为but I don’t know what country he is studying in.若选D项，应改为：but I don’t know what country he has studied in.
解题方法与技巧：由题干“I don’t know what country he studied in”可得知“他在国外学习这一动作发生在过去”。故答案为A。
答案：A
