英语语法——宾语及宾语从句
英语语法——宾语及宾语从句目录∙宾语的种类∙宾语表示法∙双宾语∙复合宾语∙用it做宾语∙宾语从句——由that引导的宾语从句∙宾语从句——由连接代（副）词引导的从句∙宾语从句——由关系代词型what引导的从句内容∙宾语的种类∙一、宾语宾语是动作、行为的对象，是动作的承受者。
宾语由名词、代词、不定式或相当于名词的词、短语来担任。
当然,也可以由一个句子来充当,称之为宾语从句,所以一个句子中不一定只有一个宾语.英语的及物动词后必须有宾语。
宾语一般放及物动词之后，它和及物动词一起说明主语做什么。
说明，除及物动词有宾语之外，英语介词后面也要有宾语。
另外，某些形容词如wo rth,careful 等后也可有宾语。
二、宾语的种类1.直接宾语——绝大多数及物动词都跟有直接宾语，成语动词有些也跟有宾语，表示动作的对象、承受者或后果：We lo ve o ur motherland.我们热爱祖国。
（动作对象）They robbed a bank. 他们抢劫了一家银行。
（动作承受者）Then he co mposed a symphony. 此后他谱写了一曲交响曲。
（动作结果）Who put fo rward the suggestion? 这建议是谁提出的？2.间接宾语——双宾动词后可跟两个宾语，一个是直接宾语，一个是间接宾语，间接宾语表示动作是向某人或为某人做的：主语谓语间接宾语直接宾语Auntie gave me a to y car.My wife sends yo u her greeting.I will play yo u some light music.He bought himself a new tie.3.复合宾语——是由两部分构成的宾语，后面部分可称为宾语的补语：主语谓语复合宾语They asked him to speak at the meeting.She saw a girl waving to her.My kids never heard the song sung in Italian.They elected him vice-president.∙宾语表示法∙宾语一般用在及物动词的后面，表示行为动词所涉及的对象。
