主语的总结 第1篇

主语是英语句子中一个主要语法成分,是句子中出现的第一个独立名词或具有名词词性的短语或是句子。主语表示句子描述的是“谁”或“什么”,是谓语的陈述对象,由名词性的成分来充当,说明人物、地方、行为、事件、事实等。下面我们通过从主语的形式上来讲一下如何认定主语。

英语中的主语是独立的名词性质的词或短语,除了名词和代词之外,名词性的成分还包括:

(一)the+形容词,表示某一类的人或事物,如the rich,表示富人。

(二)动词的非谓语形式(不定式或动名词)可起名词作用。

1、不定式作主语

(1)当不定式作主语时,如果较短,可直接出现在主语位置。

(2)如果不定式充当的主语较长而谓语较短时,常用形式主语“it”放在谓语之前,而把真正的不定式主语放在句子后面。如:It is my duty to take care of these kids。

(3)有时,不定式的前面可以有一个连接词、连接代词或连接副词(包括whether, what, which, whom, where, when, how)。如:Where/When/How/Who to prepare the dinner is not decided yet。

2、动名词作主语

动名词相当于一个名词,可以充当句子主语。如:Being a man has always been dangerous。

还有一种情况,当动名词有自己的逻辑主语时,其前加上一个名词或代词的所有格,构成动名词的复合结构(这时,名词或代词的所有格做动名词的逻辑主语)。动名词的复合结构也可以在句中作主语。如:Everyone’s being the same in survival and number of offspring means that natural selection has lost 80% of its power in upper-middle-class India compared to the tribes。

(三)主语从句

句子也可以起名词作用,在句子中充当主语,形成主语从句。判断主语从句时,可先找到句子的谓语,谓语前面的从句就叫做主语从句。如果主语从句较长,而谓语动词比较短,也可以借助形式主语it,主语从句放在谓语后面。
