问题描述:
i lost a set of keys ,i can't find them 还是it.
答
them
他显然要找的是key 而不是那个set但我查了一下,a set of keys 是作为一个整体,单复数看两次set 而且谓语动词也是根据set填写,如是a set of keys 那么谓语动词就要用is,但就是用代词去代指时就搞不明白了咯A number of people are playing football over there.A lot of people are playing football over there.量词 对不, 不是绝对的吧。a set of keys->一串钥匙 你找的是串, 还是钥匙 。 哈哈
