一般疑问句、否定句、特殊疑问句的改法.doc

简易英语语法 动词的分类 Be动词：is, am, are, was, were 助动词：do, does, did, has, have, had 动词 情态动词：can, must, may, should, 等 实义动词：run, eat, play, like, 等等。 陈述句改为一般疑问句的改法： 一般疑问句：以be动词、助动词、情态动词为句首，句末有问号（？）的句子。例如： Is she a doctor. 她是一名医生吗？ Has she got any grapes? 她有些葡萄吗？（这里的has是助动词，got（get的原形）是有的意思。 Can you fly? 你会飞吗？ 当句子中的谓语只有实义动词，没有be动词、助动词、情态动词的时候，句子变一般疑问句时要加do、does、did（do、dose的过去式）其中之一。如：The fox likes grapes. 句子的谓语没有be动词、助动词、情态动词，只有likes，like是实义动词，因此，句首要加助动词；又因为the fox是第三人称单数，句首的助动词就用does. 句子的就变成Does the fox like grapes? 注意原来likes中的s，要删除。 一般疑问句主语和be动词、助动词、情态动词倒装。没有这三类词时要加助动词。如： She is a doctor. She usually goes to school at seven. Is she a doctor? Does she usually go to school at seven? 记住：实义动词始终在主语的后面。 注意：述句（句子后面只有句号的句子）给成一般疑问句时，一般情况下，还要把第一人称I、we、my、our改成you、your，把some变成any。如： I have got some apples. I am making my aeroplane. 变成：Have you got any apples? Are you making your aeroplane? We are watching TV. 变成：Are you watching TV? 还要注意：如果has、have、had、do、does、did后面是名词时，has、have就不是助动词了，他们是实义动词。改一般疑问时不能提前（一般情况下，所有实义动词都不能提到主语前面），要根据时态加助动词do、does、did。 如：She has breakfast everyday. Does she have breakfast everyday? 练习，把下列的句子改成一般疑问句。 1. His father is an English teacher. 2. These cats are crying. 3. They can swim. 4. I like to read English. 5. I go to school on foot. 6.
