如果前面不用的話：有兩種情況
如果意義為復(fù)數(shù),謂語動(dòng)詞用復(fù)數(shù)
如：The fishing and the hunting in Arizona were good that year.
如果作主語的并列結(jié)構(gòu)不是指兩個(gè)或兩個(gè)以上的人或物,而是表示單數(shù)意義,則動(dòng)詞用單數(shù).
如：Ham and eggs is a good breakfast.
用的話：都用單數(shù)Every train and bus was crowded with many people.把every去掉怎么改Trains and buseswere crowded with many people.吧^_^那個(gè)蛋后面干嘛要加s 還有不可數(shù)名詞用復(fù)數(shù)還是單數(shù)？如果用and的話不是都只是兩個(gè)么 哪來兩個(gè)以上哦上面是一定要+s的吼不可數(shù)名詞用單數(shù)哦有兩個(gè)以上的哦，如You,he and I are all friends.這就是一例哦
