lots 不單獨(dú)用的,lots of＝a lot of 后面接可數(shù)名詞和不可數(shù)名詞均可,接可數(shù)名詞時(shí)謂語用復(fù)數(shù),接不可數(shù)名詞時(shí),謂語用單數(shù).
a lot 當(dāng)然不是名詞性短語了,而是副詞性短語,修飾動詞.比如：Thanks a lot.= Thanks very much.
再比如：I know him a lot.
plenty of 和以上lots of 和a lot of相似,后面接可數(shù)名詞和不可數(shù)名詞均可,接可數(shù)名詞時(shí)謂語用復(fù)數(shù),接不可數(shù)名詞時(shí),謂語用單數(shù).
much 只能修飾不可數(shù)名詞
many 只能修飾可數(shù)名詞復(fù)數(shù)
a great number of 也只能修飾可數(shù)名詞復(fù)數(shù),謂語用復(fù)數(shù).經(jīng)常和the number of 作區(qū)別,the number of……表示……的數(shù)量,后面接可數(shù)名詞復(fù)數(shù),但謂語用單數(shù).
some 表示一些,和a few同意,后面接可數(shù)名詞復(fù)數(shù)或不可數(shù)名詞都可以.
several表示“幾個(gè)”,后面接可數(shù)名詞復(fù)數(shù).
