初三英语知识点大全:句子种类分析
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,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,ill you?
在省略的感叹句后面,要注意主语的单复数。 如What fine eather,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,fe,nothing,nobody,fe,seldom,hardly,little 等否定含义的词时,疑问部分用肯定含义. 如 He seldom ca 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ouldn't+主语. 如You'd like to go ith , ouldn't you?
主语是everyone, soone,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,sothing,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ill you。如 Don't do that again, ill you? 注意 Let's 开头的祈使句,后用shall e? Let us 开头的祈使句,后用ill you?
