人們利用它們來數(shù)數(shù)，像每個月的天數(shù)，食物的數(shù)量還有他們所擁有的牲畜的數(shù)目。

amount用作名詞，意為“數(shù)量；總額”，通常用于a(great/large)amountof短語中，表示“大量；許多”，其后通常接不可數(shù)名詞。例如：

Hemadealargeamountofmoney.

他賺了很多錢。

注意theamountof和thenumberof的區(qū)別：這兩個短語都表示“……的數(shù)量”，其區(qū)別在于:前者與不可數(shù)名詞連用，而后者與可數(shù)名詞的復數(shù)形式連用。例如:1.Theamountofrainaffectsthegrowthofcrops.降雨量影響農作物的生長。2.Thenumberoftigershasreduced

sharplyinthelastfiftyyears.

在過去的五十年里，老虎的數(shù)目銳減。而a(great/large)amountof和a(great/

large)numberof都表示“大量；許多”，其區(qū)別在于前者與不可數(shù)名詞連用，而后者與可數(shù)名詞的復數(shù)形式連用。例如：1.Alargeamountofmoneywasspentonbooks.

一大筆錢花在了購買圖書上。2.

thattheycouldcarrythemaroundeasily.他們經(jīng)常把代幣懸在繩子上，這樣他們可以輕松地四處攜帶它們。【句型】sothat

引導目的狀語從句時，意為“以便；為了”，從句中常使用can，could，may等情態(tài)動詞。注意，so...that...引導的是結果狀語從句，意為“如此……以至于……”，試比較：為了趕上早班車，他今早很早就起床了。Hegotupearlythismorningsothathecouldcatchtheearlybus.他今早起得太晚了，以至于錯過了早班車。Hegotupsolatethathemissedtheearlybus
