1、目的状语
(1)、①引导目的状语的结构：to do/ so as to do/ in order to do/ in order that/ so that.
②引导结果状语的结构：to do/ so + 形容词；副词+ as to do/ so + 形容词；副词；分词；(限定词+ 名词) +that/ such + (单数；复数；不可数)名词+ that/ so (that)
(2)、order作“订购”讲时，只用陈述语气。如：I have ordered a set of books for the students each
(3)、不用order to do something, 要改为从句。
(4)、in order to/ so as to表示目的，so … as to/ enough to/ too … to表示结果，作目的状语的否定结构避免单独使用not to do来表达，要用so as not to/ in order not to。
(5)、so that 和in order that (正式语体)，意思为“以便，使能够，为的是”，主从句的主语相同与否均可，目的状语从句中常用情态动词can, could, may, might, will, would, should 等。如：I got up early so that I (caught) could catch the train. 主从句的主语一致可转换成不定式in order to 或so as to ，句子的主语通常是不定式的逻辑主语。so as to, so that, in order that表示目的，不能放在句首。

2、 as从句
在as引导的非限制性定语从句中，连接代词as在句子中可以作主语、宾语或表语等，可以指人或物。其在定语从句中的位置比较灵活，即可以在句子前面，在句子中间或句子末尾。常用的结构有：as we all know; as is well known to…; as is often the case; as is said/mentioned above; as has been said before; as I told you before; as is evident; as often happens; as can be seen; as is/was expected; as we expect; as I can remember等。
注意：
①as通常只指整个句子的内容，不表示部分内容。
②as引导的非限制性定语从句通常指“事先可以预料到的”“料想到的”，表达“好”的方面。
③as引导限制性定语从句时，常构成the same…as…; such…as…; so/as …as…等结构。在从句中既可以指人、物，也可以指整个句子。
例如：
①This is also part of your work, as I told you before. 我曾告诉过你，这也是你工作的一部分。
②The man was a teacher, as was evident from his way of speaking. 从那人说话的样子可明显看出，他是个老师。
③Such ideas as he hits on are worthless. 像他那样偶然想起的主意是无用的。
④It’s the same story as I heard from her yesterday. 这故事跟我从她那儿听到的相同。
⑤He will marry as pretty a girl as he can find. 他要尽可能找漂亮的女孩结婚。
⑥Such people as have made great contributions to the world should be greatly respected. 那些对世界做出巨大贡献的人们应该受到极大的尊重。

3、疑问词加不定式
(1)、“疑问词加不定式”在句中起名词作用，可作主语、宾语、表语等，不能作状语。它通常可以相当于一个从句。如：I don’t know what to do = I don’t know what I should do. 疑问词必须位于不定式前，疑问代词what, which, whom作不定式的宾语，疑问副词where, when, how作不定式的状语，不定式必须用主动形式。
(2)、在这个结构中，不定式中的动词必须是及物的，不及物动词应该加上相应的介词。有些动词之后适合接这个结构作宾语，否则句意不完整。
(3)、这类动词常用的有16个，可借助下面的口诀来记忆：知道记住忘理解；想知解释查明白；决定告诉想考虑；讨论表明问和学 (know, remember, forget, understand, wonder, explain, find out, see, decide, tell, think of/ about, consider, discuss, show, learn, ask)。

A. how to make dresses B. how dresses be made

4、双重问句
（1）、复杂的特殊疑问句，又叫双重疑问句，它融一般疑问句与特殊疑问句于一体。
（2）、本句型分为两部分：第一部分为一般疑问句；第二部分为特殊疑问句，但其疑问代（副）词要放在句首。如: We haven’t heard from Jane for a long time. What do you suppose has happened to her?
（3）、注意事项：
1)、特殊疑问句虽被分割，但仍是一个整体。中间的do you suppose似乎像是插入语。
2)、第二部分并不是严格意义上的特殊疑问句，因为有了do you suppose，它不再使用疑问句语序，而要用陈述句语序。如：Why do you suppose the accident has happened?
3)、句子的重心在第二部分，虽有do you suppose存在，不能用yes，no回答。与特殊疑问句相同，要根据疑问词做具体的、针对性回答。如可回答：The accident happened because of the driver’s carelessness / because the driver was careless. 也可用I/ We think (believe, expect, suppose, imagine, guess) so. 进行肯定简略回答或用I don’t think (believe, suppose, imagine)./ I believe (suppose, imagine, hope, guess) not. 进行否定简略回答。
练习：
①___ be sent to work there?
A. Who do you suggest B. Who do you suggest that should
C. Do you suggest who should D. Do you suggest whom should
②___ you have seen both fighters, ___ will win?
A. Since; do you think who B. As; who you think

D. Do you think of whom; be married to
⑦I haven’t heard from Henry for a long time. What do you suppose ___ to him?
A. was happening B. to happen
C. has happened D. had happened
5、状语从句的省略
（1）、当某些表示让步、时间、条件的状语从句中的主语与主句中的主语相同，且谓语动词又包含be动词，那么这种状语从句中的主谓都可省略。由单词 though, when, while, if, till, until等引导的状语从句可省略。如：The article is very important though (it is) short.
When (he was) still a boy of ten, he started working to support himself.
Do not leave the machine till (you are) told to do so.
If (he is) too old to work much, the retired worker is very enthusiastic about neighborhood affairs.
（2）、若从句的主语是it，谓语是系动词 be，可省去 it be。如：If (it is) necessary, write to me.
