--句法
一、句型
(一)肯定句
(二)否定句
be动词(am、is、are)+not、
情态动词can+ not、
助动词(do、does) + not
如何将一个肯定的陈述句改为否定句:
1.看句中有无be动词,如有,直接在be动词后+ not。
2.看句中有无情态动词,如有,直接在情态动词后+ not。
3.如上述二者都没有,就应用助动词+ not。
(三)一般疑问句
肯定陈述句中本来是没有助动词的,要加上去,位置在主语(某人或某物)后,动词前。
确定助动词用do、does,根据句中动词,动词是原形的助动词就用do,动词是第三人称单数的助动词就用does,
在助动词后加not。
原句中动词假如发生变化就要恢复成原形。
强调一点,有some的要考虑是否要用any。

What time 什么时间 问具体时间,如几点
Who谁问人 Whose 谁的问主人
