e.g.

→She saw the butterflies dancing among flowers.

→ He found his bedroom in a complete mess.
此类常用动词有：
see, hear, think, believe, find, consider, wish…
2. (1) 从句可改为“主+谓+宾(疑问词+to do作宾语)”结构的简单句
e.g.
① I don’t know what I should do.
→I don’t know what to do.
② She can’t decide which she should choose at the shoe shop.
→She can’t decide which to choose at the shoe shop.
此类常用动词有：

(2) 从句可改为“主+谓+宾(表语后介词短语作宾语)”结构的简单句
e.g.

→Are you aware of the distance between the Mars and the Sun
② I am sure that the concert tickets will be expensive.
→I am sure about the high price for the concert tickets.

be aware that = be aware of
be sure that = be sure of/about
think that = think of/about
agree that = agree with/be in agreement with
remind sb. that = remind sb. of
wonder that = wonder about
此类从句更改规则：
将从句中的动词、形容词和疑问词改为对应的名词或名词短语。
① I’m sure that he will come here tomorrow.
→I’m sure about his coming tomorrow.
② I doubt if it is necessary to learn English well.
→I doubt about the necessarity of learning English well.
③ Do you know how many people there are in India
→Do you know the population of India
注意：不是所有的疑问词都必须改成一样的名词，需要根据句子的意思来定。
① Do you know how many people there are in India
→Do you know the population of India
→Do you know the number of people in India
② I wonder how many detective books you have.
→I wonder the number of your detective books.
此句中的the number of则不可以改为population
3. 从句可改为“主+谓+间宾+直宾(疑问词+to do作宾语)”结构的简单句
e.g.

→Can you tell me where to find the hospital

→I’m too tired to step forwards any more.

e.g.

(1)可用without 或with 来转换条件状语从句
e.g.
① Plants won’t die if there is enough water.
→Plants won’t die with enough water.
② If you don’t help me, I won’t pass the exam.
→I won’t pass the exam without your help.

If you work hard , you’ll pass the exam easily.
=Work hard , and you’ll pass the exam easily.
=Work hard , or you won’t pass the exam easily.
