由两部分组成，前半句为陈述句，后半句是一个附着在前半句上的简短问句，回答时用Yes或No．它的构成和回答主要如下：
１）如果前半句是肯定句，那么后半句是否定的缩写形式． e.g. They are interested in collecting stamps, aren’t they? --- Yes, they are. 是的．他们对收集邮票感兴趣． ---No, they aren?t. 不，他们他们对收集邮票不感兴趣.
２）如果前半句是否定句，那么后半句就用肯定形式加代词构成
e.g: Tom didn’t pass the exam, did he?
-- Yes, he did. 不，他通过了考试． -- No, he didn’t. 是，他没通过考试
三、祈使句
1、含义：表示命令、请求、建议、劝告的句子被称为祈使句。它所表达的动作通常都还未发生的，因此，对这类句子的应答通常用“一般将来时”。祈使句都省略了第二人称you。 2、祈使句以动词原形开头，否定的祈使句以Don?t+动词原形开头。 3、祈使句的反意疑问句，由“will you” 或”shall we”构成． 4、Let us ……, will you? Let?s ……, shall we? e.g. Don?t walk on the grass.
A: Please wait me at school gate. B: Ok, I will. A: Don?t play football in the street. B: No, I won?t. 5、祈使句与条件状语从句的互相转换：
2
祈使句 + and +一般将来时， 表示“递进”。 祈使句 + or + 一般将来时，表示“否则……” Stand up and you will see him clearly. If you stand up, you will see him clearly. Stop or will fire.
If you don’t stop, I will fire.
6、祈使句的反意疑问句的变化： Let?s have a picnic, shall we?
Please open the window, will you? Please don?t close the window, will you? Let us have a barbecue, will you? 四、感叹句
1、含义：感叹句表示说话时的惊讶、喜悦、赞赏和愤怒等 情绪。
2、感叹句是由what和how引导，其句型结构为“What/How+感叹部分+主语+谓语！”。 3、What 引导的感叹句
１）What + a (an)+形容词+可数名词单数+主语+谓语！ What a beautiful voice she has!她的声音多美啊！ ２）What+形容词+可数名词复数+主语+谓语！
