A.220metrewideB.220metreswide

2.hundred,thousand和million在表示定量数量时，不用复数形式；在表示不定量数量时，用hundredsof,thousandsof和millionsof形式，如：
threehundredbooksseveralmillionyearshundredsofpeoplethousandsofstars
Eg.
①.Yesterdaymymotherbought__________eggsinthemarket.Unfortunately,shebroketwoandtenwereleft.
A.adozenB.dozensofC.dozenD.severaldozens
【分析】易错题。
dozen解释为“一打”，12个，从后文“...twoandtenwereleft”可以判断一共12个，即adozen.
.I’veread__________sportsmewsabouttheNationalSportsMeeting.
A.twoB.piecesC.twopiecesD.twopiecesof
.--__________thepopulationofChina?
--It’sabout__________.

④.Duringtheseven-dayNationalDayholiday,__________thefamiliesinthecommunitywent
sightseeing.
A.twohundredB.twohundredof
C.twohundredsD.twohundredsof
【分析】易错题。
易错项A.没有注意到短横线后的名词families前有定冠词the，表示“这个社区里所有家庭中的200个家庭”。
若没有the，则选择A.
⑤.About__________thestudentshavelearnedhowtousePPTtogiveapresentation.
A.threehundredsofB.threehundredofC.threehundredD.hundredsof
【分析】填空部分后面的students前面有定冠词the限定，表示特指范围内的一群学生，所以应与介词of连用。
而要表达整体范围内的具体数量，则直接用“数词+单位（单数）”形式表达就可以了。
⑥.__________ofstudentsdonatedmoneyandclothestothevictimsthroughtheRedCrossaftertheylearnedthenews.
A.HundredsB.Hundred
C.FivehundredD.Severalhundred
