as...as为什么变否定句时会有not so.as?so...as与as...as算是同义句吗? so...as和as...as有什么区别?是不是用于否定句时,前面都需要加not so...as 只能用在否定句中.as...as可用于肯定和否定句 有这个说法么 as.as与so .as有何区别?是不是as.as用在肯定句中,so .as用在否定句中,还是因为别的原因? 在as as结构的否定句中 后边的as可以省略?比如 he is not as angry as before 那么 后边的as before可以省略?么he is not as angry 这句句子有什么错误?怎么改?Walking is not as tired as jogging.not so...as 和 not as...as 都可以用的!!!!!!!!! I am not （so还是as）healthy as himnot as as 是不是等于so as as as不是用在肯定句中么，这不是否定句么，怎么也能用呢 so as只能加not用于否定句吗?不能的单独用于肯定句? not as as与not so as有什么区别 not as as与not so as 有什么区别 not as.as和not so.as有什么不同? 主题:as…as,not so…as,not as…as有何区别 She is not as strong as he is .句中最后一个IS能省么?为什么? Nancy is as thin as Yang Ling.(否定句) Tom jumps as far as Mike(改为否定句） English is as easy as math.否定句怎么说? Jim runs as fast as Tom.(否定句） I live as happliy as before.改为否定句
