she does her homework and usually swims or takes a walk为何swim和take还加s

题目

she does her homework and usually swims or takes a walk为何swim和take还加s
does已经表示出了第三人称单数

答案

因为这是一个并列句,这句话中does,swims,以及takes是三个并列的谓语动词,所以依据英语中关于一般现在时态对谓语动词的语法规则,这三个谓语动词都要加s
注：关于一般现在时态的语法,即当时态是一般现在时态时,且主语是第三人称单数时,谓语动词要加s或es
不知我说的能否让你明白,不懂可继续追问
