主语的概念:执行句子的行为或动作的主体。

常用作主语的结构:主语一般由名词、代词、名词短语或相当于名词的结构来充当, 一般常用作主语的结构有名词代词、名词短语、to do 不定式、doing 动名词短语及从句等。

【例】Such an attitude would emphasize sharply the values of life. (名词词组)

【例】To see is to believe. (to do 不定式)

【例】Chatting on the Internet brings me a lot of fun. (动名词短语)

特殊情况:

① 祈使句:祈使句以动词原形开头,但并非没有主语,祈使句默认的主语为 you。

【例】Remember to turn off the light.

② it 作形式主语:it 作句子的形式主语时,真正的主语是后面的 to do 不定式。常见结构为:it + be + adj./n. +(for/of sb) + to do sth。

【例】It is not difficult to imagine a world short of ambition.

③ 倒装句:句子主语在谓语动词或助动词/情态动词之后。

谓语:

谓语的概念:表示主语动作的词语和词组。注意:

谓语一定是动词,但是句子中的动词不一定是谓语。

一句话中只有一个谓语动词。(此处一句话指一个简单句)

常用作谓语的结构:


用于表达句子的时态语态,例如:一般现在时为 do/does,一般过去时为 did,现在完成时为 have / has done 等。

【例】 Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer.

情态动词 + do / have done 构成句子的谓语动词。

【例】He must drink a lot of milk. 他得多喝牛奶。

谓语动词的分类: 1) 系动词

① be 动词:am/is/are; was/were

【例】The problems of your past are your business.

② 感官动词:情态动词 + do / have done 构成句子的谓语动词。

【例】The iron feels hot. 这块铁摸起来很热。

③ 表示“保持”的动词:continue、keep、stay、remain、sit、stand、lie 等。

【例句】The weather continued fine for several days. 天气连续几天都很晴朗。

④ 表示“变成”的动词:become,grow,get,turn,fall,go,come 等。表示主语由一种状态变为另一种状态。

【例句】Our supplies of sugar and rice fell short. 我们的糖、米供应不足。2) 及物动词:可以直接接宾语的动词。

【例句】Just like instant coffee, they want instant happiness.

不及物动词:不能直接接宾语、需要加介词后才能接宾语的动词为不及物动词。

【例句】The benefit of the world matters before personal benefit.

双宾语动词:其后需要接两个宾语,直接宾语和间接宾语。双宾语中既有人又有物, 一般“人”表示动作的接受者,为间接宾语,“物”表示动作作用的对象,是动作的承受者,为直接宾语。常见的双宾语动词有 give,borrow,lend,send,bring,pass,buy, tell,ask,teach,show 等 。
