英语中的句子按其语义功能划分为陈述句、(肯定句和否定句)、疑问句(一般疑问句、特殊疑问句、选择疑问句、反义疑问句)、祈使句和感叹句。
1、陈述句：说明一个事实或陈述一种看法。
Light travels faster than sound.(光比声速度快)
The film isn't interesting.(这部电影很乏味)
2、疑问句：
①一般疑问句 Can you finish the work in time?(你能按时完成工作吗?)
②特殊疑问句 where do you live?(你住哪?)
③选择疑问句 Do you want tea or coffee?(你要茶还是要咖啡?)
④反意疑问句 He doesn't know her,does he?(他不认识她，对吗?)
祈使句：提出请求，建议或发出命令，祈使句的肯定句都是以动词原形开头，其否定句都是在动词原形前加don't。
Sit down ,please.(请坐)
Don't be nervous!(别紧张)
句中有以下词的,直接在这些词后面加NOT:
1.BE动词(am/is/are/was/were)2.情态动词(can/may/must/need/should.)3.的在其后加NOT,构成时态和语态的助动词(has/have/will/be...)
如:
I can swim.-------I can't swim.
She will come to see me next week.-----She (will not)(或won't) come to see me next week.
如果没有以上的词,则句子为一般现在时或一般过去时的肯定形式,变否定句时,先将动词变为原形,在动词前面助动词DO(DOES/DID),并在助动词之后加否定词NOT.助动词要根据时态和人称选用相应的.一般现在时用DO/DOES,其中DOES用于第三人称单数主语,DO用于除第三人称单数之外的其它主语.DID用于一般过去时,不论人称.
例如:
He goes to school on weekdays.-----He (doesn't go) to school on weekdays.
We went shopping last Monday.-------We (didn't go) shopping last Monday.
We like watching TV.------We (don't like) watching TV.
另外,除了NOT ,还有一些具有否定意义的词,以上是基本的,先记住这些.以上这些词变疑问也是要提前的.
is,do后面加not
基本上＋not，no这种表否定的单词
