句子种类（一）
根据句子的使用目的，句子可分为陈述句，疑问句，祈使句，感叹句。
疑问句是常考的重点，也是要掌握的难点，
疑问句中讲一讲难掌握的反意疑问句和特殊疑问句.
1.反意疑问句:
在陈述句之后附上一个简短问句，对陈述句所叙述的事实提出相反的疑问,这种疑问句叫做反意疑问句. 如前面陈述句部分是肯定式，后面问句部分一般用是否定式；如前一部分是否定式，后一部分一般用肯定式.前后两部分在人称，数及时态上通常保持一致. 如：You are a student，aren't you?(你是学生，对吗?)
在祈使句后面用反意疑问句，要注意人称的变化。如：Go to the cinema，will you?
在省略的感叹句后面，要注意主语的单复数。如：What fine weather，isn't it?
陈述句部分的主语如是I，疑问部分要用aren't I.如: I'm as tall as your sister，aren't I?
陈述部分用never，hardly，few，nothing,nobody,few,seldom,hardly,little等否定含义的词时，疑问部分用肯定含义. 如: He seldom came here,did he?
陈述句部分的谓语是used to时，疑问部分用didn't+主语或usedn't +主语.如: He used to go to school at seven, didn't he? / usedn't he?
陈述部分有had better + v. 疑问句部分用hadn't you?如: You'd better read it by yourself, hadn't you?
陈述部分有You'd like to +v.疑问部分用wouldn't+主语. 如：You'd like to go with me, wouldn't you?
主语是everyone，someone，anyone，no one等不定代词时，多用they 指代.如：Everyone is here，aren't they?(所有的人都来了吗?)
主语是everything，something，anthing，nothing时，用it 指代。省去主语的祈使句的反意疑问句，疑问部分用will you。如: Don't do that again, will you? 注意Let's 开头的祈使句，后用shall we? Let us 开头的祈使句，后用will you?
陈述部分是"there be"结构的，疑问部分用there省略主语代词。如: There is something wrong with your watch, isn't there?
2.特殊疑问句=疑问词+一般疑问句
