一、 如何变否定句。

句子变否定句时分为两种情况:有助动词和无助动词。

1、 有助动词的句子。

有助动词的句子变为否定句时,直接在助动词后面加not。常见的助动词有be动词、情态动词、h**e等。

特别注意:some在否定句中要变为any,too变为either,already变成yet。

按要求进行句型转换。

1. these photos were taken on the great wall. (改为否定句)

2. we were h**ing a pe class at four yesterday afternoon. (改为否定句)

3. there are some computer room. (改为否定句)

2、 没有助动词的句子。

没有助动词的句子,一般情况下要借用助动词do的相应形式来表达。

注意:原句中的谓语动词要还原成原形。

如:she has some books. —she doesn’t h**e any books.

i went to school yesterday. —i didn’t go to school yesterday.

1. i watched tv last night. (改为否定句)

itv last night.

2. the woman cleans the toilet every morning. (改为否定句)

the womanthe toilet every morning.

3、 特殊情况。

1) 祈使句变否定句时,直接在句子前面加don’t 即可 。

如:open the door,please. —don‘t open the door,please.

2) 某些词汇可以直接变为其反义词:both—neither,all—none等。

注意:谓语动词的单复数要做相应变化。

如:both of my parents like watching tv. —neither of my parents likes watching tv.

3) 特殊情况。某些句式变为否定句时有自己独特的方式,需要我们特殊记忆。

如:i think he is strong. —i don’t think he is strong.

you’d better go now. —you’d better not go now.

1. both my father and i are going to beijing next week. (改为否定句)

my father i going to beijing next week.

2. open the door,please. (改为否定句)

3. you’d better go to see him off at the railway station. (改为否定句)

you’d betterto see him off at the railway station.

4. both of the twins like mooncakes with eggs in them. (改为否定句)

of the twins mooncakes with eggs in them.
