陈述句变一般疑问句_肯定句变否定句 (1)

英语肯定句改为否定句、陈述句改为一般疑问句的方法和诀窍㈠肯定句变为否定句的方法——⑴加；⑵变⑴“加”——是指加not。

加not的规则是：原句中有“情助be”时则直接在“情助be”后加not（not可与“情助be”缩写）；原句中没有“情助be”时则需要另加助动词do/does/did, 然后在助动词do/does/did后加not（not可与助动词do/does/did缩写）。

助动词do和does用于一般现在时，did用于一般过去时。

⑵“变”——是指变化某些需要变化的词（因为某些词只能用于肯定句或只能用用于否定句）。

如：some→any（someone→anyone，something→anything，somewhere→anywhere）；and→or；too/also→either[´aiðə; ´i: ðə]；a lot of→many/much等。

另外，使用助动词does/did帮助否定时，原来的谓语动词要恢复原形。

例：1）He can swim. →He can’t swim.2）He will（将，要）swim. →He won’t(will not) swim.3）He is a good swimmer. →He isn’t a good swimmer.4）I have some English books. →I don’t have any English books.5）She can sing and dance. →She can’t sing or dance.6）Li Lei’s father has a lot of money. →Li Lei’s father doesn’t have much money.7）He went to Shanghai last week. →He didn’t go to Shanghai last week.说明：大多数英语肯定句改为否定句都符合上述规则，但也有一些特殊的情况不符合上述规则，在以后的学习中会学到，要注意积累。

一、陈述句变一般疑问句的几点技巧1、如果所给的陈述句中含有be动词（am/ is /are/ was /were)、情态动词(can/may/could/would will/shall等词时）变一般疑问句时，只将其提到句子的首位并大写第一个英文字母，其余的照抄不变，遇到some改为any, my改为your, I改为you.2、如果所给的陈述句中没有be动词（am/ is /are/ was /were)、情态动词(can/may/could/would will/shall等词时）而是有行为动词，变一般疑问句时，首先要根据主语和时态来判断。

a.当所给的句子的时态为一般现在时态且主语为第一、二人称或复数人称时则在句子首位直接加Do,其余照抄不变，遇到some改为any, my改为your, I改为you.b.当所给的句子的时态为一般现在时态且主语为第三人称单数时，则在句子首位直接加Does,原句中的动词恢复原形，其余照抄不变，遇到some改为any, my改为your, I 改为you.c.当所给的句子的时态为一般过去时态，则在句子首位直接加Did,原句中的动词恢复原形，其余照抄不变,遇到some改为any, my改为your, I改为you.二、肯定句变为否定句的几点技巧1.如果所给的肯定句中含有be动词（am/ is /are/ was /were)、情态动词(can/may/could/would will/shall等词），则直接在be动词、情态动词后加not,遇到some 改为any, a lot of/lots of对应的改为many或much.2.如果所给的肯定句中没有be动词（am/ is /are/ was /were)、情态动词(can/may/could/would will/shall等词），而是有行为动词时，则根据主语和时态来判断。
