请教真正懂行的,英语肯定句改为疑问句,否定句规则
楼主,要将理论条条框框的话最好看语法书。这里我只用一些例子来说明:
(1)肯定句:He (is) a good student。
否定句:He (is not) a good student。

疑问句:(Does he) work very hard?
(3)肯定句:He (has finished) his homework。

(3)肯定句:He (has finished) his homework。
否定句:He (has not finished) his homework。
疑问句:(Has he) finished his homework?
从以上例子,楼主可以看出,肯定句变否定句是直接在动词后加not构成,肯定句变疑问句时,如果是be动词构成的肯定句,就用am/is/are/was/were来引导疑问句,然后跟上主语;如果是行为动词构成的肯定句,就用do/does/did来引导疑问句,然后跟上主语;如果是完成时构成的肯定句,就用has/have/had来引导疑问句,然后跟上主语。
