thebag

onthefloorand

inthedark.A.left;lied;disappearedB.leaving;lying;disappearedC.leaving;lie;disappearingD.left;lay;disappear

解析分析句子知leavingthebag...是分詞短語作狀語；而thebag和lie間是主謂關系，故用lying的形式；而disappear和rushout是句子的謂語動詞；因此B正確。B第20頁/共35頁2.Therearebothadvantagesanddisadvantagesintheschemeproposed,but

Ithinkweshouldbenefitbyadoptingit.A.onbalance B.outofbalanceC.onthebalance D.offbalance

解析onbalance總的來說。A第21頁/共35頁3.Churchesareoftenbuilt

,metals

.A.heating;extend B.heated;extendC.heating;expend D.heated;expand

解析metal和heat為動賓關系，故用heated,

完整形式是：Whenitisheated,由常識知加熱時鐵膨脹，故用一般現(xiàn)在時。D第23頁/共35頁5.Theywillstarttheirproject

athelpingthepoorchildrentobeeducatedinChina’swest.A.aims B.aimingC.beingaimed D.aimed

解析分析句子知project和aimat之間是主謂關系，故用其-ing形式aiming。B第24頁/共35頁6.Afteralongdiscussionabouttheadvantagesanddisadvantagesoftheplan,theyfinallycametoa(n)

thatitwaspractical.A.decision B.opinionC.conclusion D.impression

解析cometoaconclusion得出結(jié)論?？蘸蟮膖hatitwaspractical是conclusion的同位語。C第25頁/共35頁ofthepeopleontheNet

China’seconomyisamongthestrongestintheworld.A.Fourfifth;believesB.Fourfifth;believeC.Fourfifths;believeD.Fourfifths;believes

解析考查分數(shù)表達和主謂一致。當分數(shù)中分子大于1時，分母需用復數(shù)，故排除A、B兩項；

“分數(shù)/百分數(shù)+of+名詞”作主語時，謂語動詞的單復數(shù)取決于名詞，本句中people為復數(shù)，故選C。C第26頁/共35頁8.The

flightCA9525for11∶30a.m.istobeputoffduetothestormyweather.A.ordinary B.commonC.formal D.regular

解析本題考查形容詞辨析。regular正常的；通常的；ordinary普通的，長相一般的；

add表示“加上”。根據(jù)句意選B項。B第28頁/共35頁10.Mrs.Brownwas

tohaveleftforFrancelastweek,butsomethingelsedelayedhim.A.designed B.ableC.possible D.supposed

解析besupposedtodo...本應該,原來；bedesignedtodo...打算做……。根據(jù)空后的tohaveleft知D項正確。D第29頁/共35頁11.Itwasdifficulttoguesswhathistothenewswouldbe.A.reaction B.opinionC.comment D.impression

解析one’sreactiontosth.表某人對……

的反應，此時介詞用to。A第30頁/共35頁12.Isn’t
