Did your friend( )a dinner just now用have还是has

问题描述:

Did your friend( )a dinner just now用have还是has

have
Did 接动词原形可是your friend是第三人称单数啊,不是要用has么但在助动词do, did, does 之后,动词不再有三单形式, 所以不能是has嗯,那假如是when was he get here的get需不需要变成getswhen was he get here 这个说法是错的, was 后接get, gets 都是错的, 没有这样的动词形式
when he 【gets】 here, 当他到这儿的时候, (一般现在时)
