both在句中的位置

问题描述:

both在句中的位置
both和all在句中的位置是位于be动词之后,行为动词之前,如有情态动词或助动词,则位于情态动词或助动词与主动词之间.书上写的,那这句话You cannot read both books at the same time.both为什么不在cannot与read之间?
还有You and I are both tired.为什么不是both you and I are tired.
This book is in both Chinese and English.为什么不是This book is both in Chinese and English.

Both 用于表明动词意指的行为或状态,可单独用于两个实体中的任一个.
但是,当动词不能单独用于实体中的任一个时,用both 是不恰当的.在所有格结构中,of both 通常是更确切的:the mothers of both(他们的母亲) (而不是 both their mothers ); the fault of both(他们的过错) (而不是 both their fault 或 both's fault ).
当both 与 and 在句子中用于连接平行成份时,连接的词或短语应在语法上保持一致:in both India and China (在印度和中国)或 both in India and in China (而不是 both in India and China )
解释你的问题:
1)强调那两本书,就应该是both books.就是说,强调什么,both就在那个东西的前面.再比如:The two sisters can both drive cars是这两位姐妹都会开汽车.如果是The two sister can drive both cars是这两辆车,她们都能开.
2)you and i are both tired 跟both you and i are tired语法上都可以的.
只是一个强调“都累”,一个强调“你我两人”.
3)This book is in both Chinese and English.和This book is both in Chinese and English.
就是上面说的当both ...and 在句子中用于连接平行成份时,连接的词或短语应在语法上保持一致.如果要用后者,应该说this book is both in Chinese and in English.
