become的三单形式

become: 过去式became,过去分词become,现在分词becoming

你好!become 现在分词:becoming

become的第三人称单数形式是becomes

becomes

do not /does not become 看主语是否是单三

become: 过去式became,过去分词become,现在分词becoming

答案是:如果是一般现在时,要看主语是否是三单形式,根据情况加上助动词do的适当形式,比如:He becomes tired Does he become tired ?He doesn't become tired如果是过去式就要加上 助动词did 比如:His father became ill suddenly Did his father become ill suddenly ?His father didn't become ill suddenly.

动词单三形式的构成规则:①一般动词在词尾加-s②以字母s,x,ch,sh结尾的动词加-es③以o结尾的动词一般加-es④以辅音字母加y结尾的动词,先变y为i,再加-es我目前所知道的不规则变化就只有实义动词(助动词)have了,它的单三形式是has.我的答案绝无抄袭,完全是老师讲的,选我吧

以下写出它们的现在分词和单三. be build buy can catch am,is choose come cost cut are dig draw drink drive beat fall feel find fly become forget freeze grow hang blow hear

一般现在时里用is 一般过去时用was 过去完成时以及被动语态中用has been
