優(yōu)質(zhì)解答

them
他顯然要找的是key 而不是那個(gè)set但我查了一下，a set of keys 是作為一個(gè)整體，單復(fù)數(shù)看兩次set 而且謂語動(dòng)詞也是根據(jù)set填寫，如是a set of keys 那么謂語動(dòng)詞就要用is，但就是用代詞去代指時(shí)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.量詞對(duì)不，不是絕對(duì)的吧。a set of keys->一串鑰匙你找的是串，還是鑰匙。哈哈
