句子类型
知识点1:陈述句
1. 陈述句:
陈述句是用来陈述一个事实或表达说话人看法(包括肯定和否定)的句子。通常用降调,句末用句号“.”
Tom has a new car.
The flower isn’t beautiful.
2. 陈述句否定式的构成
(1) 如果肯定陈述句的谓语部分含有助动词、情态动词或连系动词b e,则只需在这些动词后加not即可构成否定式。
He is playing the guitar.(肯定)
He is not playing the guitar.(否定)
We can get there before dark.(肯定)
We can’t get thee before dark.(否定)
(2) 如果陈述句 的谓语动词是实义动词,而其中又没有情态动词或助动词时,则需根据人称和时态在该实义动词前加don’t, doesn’t或didn’t。同时把该实义动词变为原形。
He plays the violin well.(肯定)
He doesn’t play the violin well.(否定)
She won the game.(肯定)
She didn’t win the game.(否定)
(3) 如果句子是there be结构或谓语动词是have(有),除了be和have之后加not之外,句中如果有some要变为any。例如:
There is some water in the cup. →There is not any water in the cup.
He has some books. →He has not any books.
(4) 除not以外,否定词no, never, nothing, nobody, few等也可构成否定句。例如:
There is something wrong with his bike. →There is nothing wrong with his bike.
I have seen the film. →I have never seen the film.
