初中英语语法辅导：句子种类
我们都知道，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，这里我们先重点讲一下.
疑问句中我们只讲一讲难掌握的反意疑问句和特殊疑问句.
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，arent 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，isnt it?
陈述句部分的主语如是I，疑问部分要用 arent I. 如: Im as tall as your sister，arent 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didnt+主语或usednt +主语.如: He used to go to school at seven, didnt he? / usednt he?
陈述部分有had better + v. 疑问句部分用hadnt you? 如: Youd better read it by yourself, hadnt you?
陈述部分有Youd like to +v.疑问部分用wouldnt+主语. 如：Youd like to go with me, wouldnt you?
主语是everyone， someone，anyone，no one等不定代词时，多用they 指代.如：Everyone is here，arent 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: Dont do that again, will you? 注意 Lets 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, isnt there?
特殊疑问句: 注意疑问词 how many how much , how often , how old, how long, what, what time, what day , what colour, which , when , who, whose等疑问词的用法。
