非谓语动词与独立主格：短语，句子（或者句子，短语）
1.当短语部分有独立主语，并且该主语不同于句子主语，这时短语结构称为独立主格。（它最明显的特点是短语部分有独立的主语）。
独立主格的结构1：名词（代词）+ 分词 [现在分词、过去分词]
现在分词表示主动的，正在进行的行为；过去分词表示被动的，已经完成的行为。 作题时要通过判断动作与名词（代词）之间的关系来确定是使用现在分词还是过去分词。当动作由名词（代词）发出时使用现在分词，而名词（代词）是受动者时则用过去分词。
54. Silver is the best conductor of electricity, copper _B_ it closely.
A followed B following C to follow D being followed
49. All things _A_, the planned trip will have to be called off.
A considered B be considered C considering D having considered
call off 取消； cancel vt. 取消； 四级中的考点就是现在分词和过去分词的区别。
独立主格的结构2：with + 名词（代词）+ 分词 [句子当中作状语]
36. After the Arab states won independence, great emphasis was laid on expanding education, with girls as well as boys _C_ to go to school.
A to be encouraged B been encouraged C being encouraged D be encouraged
as well as 和（相当于and）； be encouraged不会考。
动词不定式有预示将来行为的含义。to be encouraged 将要被鼓励；
been encouraged 已经被鼓励完了，与主句的谓语动词相对；being encouraged 正在被鼓励
2.短语部分没有独立主语，则短语结构称为非谓语动词。
非谓语动词的结构：分词（分词短语）
句子的主语决定非谓语动词中的分词是用主动还是被动形式。如果是句子的主语发出动作，则使用现在分词；如果动作不是由句子的主语发出，则使用过去分词。
43.No matter how frequently _A_, the works of Beethoven always attract large audiences.
A performed B performing C to be performed D being performed
perform vt. 表演，演出，演奏；
to be performed 将要被演奏； being performed 正在被演奏；
一些特殊的动词：
第一点：forget 忘记； [反义] remember 记得；
这两个词后加动词不定式表示将要进行的行为；这两个词后加动词ing形式表示已经做过的事情。
注意：动名词与现在分词形式一样，但含义不同。这两个词后加动词ing形式都是动名词。
forget to do sth. 忘记要去做某事； forget doing sth. 忘记做过某事；
remember to do sth. 记得要去做某事； remember doing sth. 记得做过某事；
62. I remember _B_ to help us if we ever got into trouble.
A once offering B him once offering C him to offer D to offer him
offer vt. 提出，提供； offer sb. sth. / offer to do sth.
him once offering 如果改成 his once offering 也正确。
动名词的复合结构：凡是一个动词的后面可以加动名词，就可以加动名词的复合结构。
动作发出者 + 动名词；当动作发出者名字给出时：名词所有格 + 动名词；当动名词的复合结构在文章中出现，且动作发出者在前文中提过时：形容词物主代词（宾格）+ 动名词。
形容词物主代词：his, her, my, your, their, our。代词宾格：him, her, me, you, us, them。
第二点：want 想要； want to do sth. 想做某事； want doing 客观需要或缺乏。
48. Your hair wants _B_. You'd better have it done tomorrow.
A cut B cutting C to cut D being cut
注意：want doing 中doing表示的是被动含义。
18. This room is so dirty that it wants _A_.

第三点：mean 意味； mean to do sth. 打算做某事，意欲… ；mean doing 意味着，…的意思是…
