b.复合谓语:
(1)由情态动词或其他助动词加动词原形构成。
如:You may keep the book for two weeks. He has caughta bad cold.
(2)由系动词加表语构成。如:We are students.
在英语中一个简单句只能有一个谓语动词(知道为什么吗),而且,我们平时学习的时态是针对谓语动词来说。
如果以do为例,do, did ,have done, will do, had done, is/am/are doing, was/were doing, would do。在简单句中,谓语动词和主语是句子的核心,是不可以随意删掉的。
3.宾语:宾语表示动作的对象或承受者,一般位于及物动词和介词后面。例如:
They went to see an exhibition(展览)yesterday.(名词)
The heavy rain prevented me from coming to school on time.(代词)
How many dictionaries do you have? I have five.(数词)
They helped the old with their housework yesterday.(名词化形容词)
4.表语:表语用以说明主语的身份、特征和状态,它一般位于系动词(如be, become, get, look, grow, turn, seem等)之后。表语一般由名词、代词、形容词、分词、数词。
Our teacher of English is an American.(名词)
Is it yours?(代词)
The weather has turned cold.(形容词)
The speech is exciting.(分词)
Three times seven is twenty one?(数词)
