thebag

onthefloorand

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

解析分析句子知leavingthebag...是分词短语作状语；而thebag和lie间是主谓关系，故用lying的形式；而disappear和rushout是句子的谓语动词；因此B正确。B2.Therearebothadvantagesanddisadvantagesintheschemeproposed,but

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

解析onbalance总的来说。A3.Churchesareoftenbuilt

thecrossintheWest.A.informof B.intheformofC.withformof D.inaformof

解析intheformof...以……样的形式；呈现……样的形式。B4.When

,metals

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

解析metal和heat为动宾关系，故用heated,

完整形式是：Whenitisheated,由常识知加热时铁膨胀，故用一般现在时。D5.Theywillstarttheirproject

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

解析分析句子知project和aimat之间是主谓关系，故用其-ing形式aiming。B6.Afteralongdiscussionabouttheadvantagesanddisadvantagesoftheplan,theyfinallycametoa(n)

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

解析cometoaconclusion得出结论。空后的thatitwaspractical是conclusion的同位语。CofthepeopleontheNet

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

解析考查分数表达和主谓一致。当分数中分子大于1时，分母需用复数，故排除A、B两项；

“分数/百分数+of+名词”作主语时，谓语动词的单复数取决于名词，本句中people为复数，故选C。C8.The

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

解析本题考查形容词辨析。regular正常的；通常的；ordinary普通的，长相一般的；

common常见的；formal正式的。D9.—Anysuggestion?—You’dbetter

thelastsentenceasitisrathermisleading.—Soundsreasonable.Thencouldyou

agoodendingtoit?A.putout;increase B.leaveout;addC.findout;find D.knockout;choose

解析leaveout此处表示“删除，省略”；

add表示“加上”。根据句意选B项。B10.Mrs.Brownwas

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

解析besupposedtodo...本应该,原来；bedesignedtodo...打算做……。根据空后的tohaveleft知D项正确。D11.Itwasdifficulttoguesswhathistothenewswouldbe.A.reaction B.opinionC.comment D.impression

解析one’sreactiontosth.表某人对……

的反应，此时介词用to。A12.Isn’t

rude

himtotalktohismotherlikethat?A.that;for B.that;ofC.it;for D.it;of

解析本题考查句式：Itis+adj.+ofsb.+todosth.的否定疑问形式。D13.—Ha
