money④Thereisonecupofteaonthetable.⑤Therearetwocupsofcoffeeonthetable.觀察例③可知，表示不定量時(shí)，some,many,afew,few,alotof,lotsof等詞語(yǔ)可修飾可數(shù)名詞；some,much,little,alittle,alotof,lotsof等詞語(yǔ)可修飾不可數(shù)名詞。以上這些詞語(yǔ)中_______________________既可以修飾可數(shù)名詞又可以修飾不可數(shù)名詞。觀察例句④⑤，Therebe句型結(jié)構(gòu)中，謂語(yǔ)動(dòng)詞的單復(fù)數(shù)與主語(yǔ)中的_______保持一致。量詞some,alotof,lotsof

名詞復(fù)數(shù)的不規(guī)則變化：

(1)元音字母發(fā)生變化。如：man→men,woman→women,foot→feet,tooth→teeth,mouse→mice,goose→geese(2)單、復(fù)數(shù)形式相同。如：deer,fish,sheep,Chinese,Japanese(3)詞尾發(fā)生變化。如：child→children(4)有些名詞只有復(fù)數(shù)形式。如：clothes,trousers,people(5)man,woman修飾其他名詞時(shí)，單復(fù)數(shù)要與被修飾的名詞保持一

致。如：amandoctor→mendoctors
