2013英语四级语法精讲

非谓语动词与独立主格:短语,句子(或者句子,短语)

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。

1. Silver is the best conductor of electricity, copper _B_ it closely.

A followed B following C to follow D being followed

2. 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]

3. 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

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。

1.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;
