? 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。 ? 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，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, seldom, 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，anything， 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? ? ? 特殊疑问句: 疑问词 + 一般疑问结构（疑问 词作主语或主语的定语时，用陈述结构） ? 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。

? 句子的种类 ? 感叹句注意事项： ? 感叹句往往由what和how引导。至于 what和how的区别则是再好辨别不过了。背 一背下面的顺口溜,感叹句你就不再陌生了. ? 感叹句用法很简单, How和What放句前, How与形、副词类连, What后面名词添.主 语谓语不用变,省掉它们也常见.
? 当然，what 感叹句和how 感叹句有时可以 互相转换。当What修饰单数可数名词时， 如果这一名词有形容词修饰，也可用how 引导感叹句，但不定冠词a或an 需放在形 容词之后。如：What a large factory = How large a factory it is!
? 祈使句: 祈使句所需注意的是：含有第二人 称的祈使句的否定句用don't.含有第一、第 三人称的祈使句的否定句用 Let + me / him not + 动词原形或 Don't let + 第三人 称代词的宾格或名词。
? 下面稍微提一下常考的强调句：我们学过 的强调句是it引导的句子。记住：强调句的 连词只有两个，that和who。当强调的部分 是人，且为句子的主语时，才用 "who"，其 余用"that". 句式是：It is (was) + 被强调部 分+that (who) + 句子其他部分。此结构强 调的成分仅限于主语，宾语和状语。判断 一个句子是否是强调句，只需看去掉It be… that是否还是一个完整的句子。
? 看下面例题： 【 C 】It is twenty years ___ Miss Feng returned to China. ? A. that B. when C. since D. as ? 本题易误选为A (that). 其实本句不是强调 句。若是，去掉It be… that还应是一个完整的 句子。而本句去掉 "Itis...that"，只剩下ten years Miss Feng returned to China.不成句。 因此本句不是强调句
