an amount of 與 amounts of的區(qū)別
只不過都是amount,amount是修飾不可數(shù)名詞：
an amount of +不可數(shù)名詞,謂語動(dòng)詞用單數(shù)；
amounts of+ 不可數(shù)n 謂語動(dòng)詞用復(fù)數(shù)同樣修飾不可數(shù)名詞
前者謂語動(dòng)詞用單數(shù)
后者謂語動(dòng)詞用復(fù)數(shù)A large amount of damage has(謂語動(dòng)詞單數(shù)) beend one by the earth quake． Large amounts of money were(謂語動(dòng)詞復(fù)數(shù)) spent on the bridge．A large amount of damage has been done by the earth quake． Large amounts of money were spent on the bridge．謝謝真專業(yè)
