文档介绍:肯定——否认
一、动词 be 的否认式
动词be根据不同的人称和时态可以有am, is, are, was, were等不同形式,可用作连系动词(表示“是”、“在”等)和助动词(用于构成进行时态和被动语态等),但不管何种情况,构成否s后面,再把something改为anything即:There is not anything wrong with the radio.
其二把something直接改为 nothing,即:There is nothing wrong with the radio.
I have something important to tell you .
把这个句子变成否认句有两种方法:
其中一种方法是先把not加在have后面,再把something变成anything,即:I have not anything important to tell you.
第二种方法是直接把something改为nothing,即:I have nothing important to tell you.
当陈述句是一个主从复合句
而主句的谓语动词是think或believe等时,把这种句子改为否认句,往往是否认think或believe等而不否认后面从句中的谓语动词,尽管意思是否认从句的谓语动词。
I think he will be back soon.
这个复合句中主句的谓语动词是think,所以在改为否认句时要在think前面加上 don't,即:I don't think he will be back soon.汉语意思:我认为他不会很快回来。
某些特殊句型改为否认句时,有不同的方法:
在陈述句中含有had better时,要把 not加在better后面,动词原形前面。
You had better go with us.
把这个句子改为否认句,要把not加在 better之后,g o之前,即:You had better not go with us.千万不要改成:You had not better to go with us.或You had better don't go with us.因为,要否认的是后面的动词不定式短语。同时,had better后面要用动词原形〔不带 to〕
当陈述句中含有both+名词或者both of+名词作主语时,改为否认句时则用neither代替both,并且要注意谓语动词数的变化。
Both of them work in the school library.
句子含有both,改为否认句时用neither代替both,同时谓语动词work改为works,即:Neither of them works in the school library.
Both answers are right.
把这个句子改为否认句,用neither代替 both,谓语动词are改为is,即:Neither answer is right.
句中含有both...and的肯定句改为否认句时用neither ...nor改写,同时neither...nor还可以把两个简单句的否认形式连成一个句子。
