上文说父亲逃避养狗这件事情,所以家人说到养狗这个话题,父亲就抱怨,表示反对。2.C

结合上文和句中“Dogs

are

a

pain.”可推知,父亲认为狗是令人头痛的东西,不想被打扰。3.D

根据下文可知,第二段讲“我”变得有责任心了;第三段讲父亲从讨厌狗变成喜欢小狗,允许狗坐在沙发上,还给他玩具玩;第四段讲,原来全家人晚饭后各自回到自己房间,不交流,现在大家一起和小狗玩耍,一起交流,增强了家庭凝聚力。总之,小狗改变了“我”们一家。ⅠⅡⅢ4.B

根据下文“I

fed,brushed

and

walked

him

every

day.”可知,“我”每天负责喂小狗、给他洗澡、遛狗,由此推断,小狗使“我”变得有责任心了。5.A

根据上文“I

fed,brushed

and

walked

him

every

day.”和下文“For

me,this

meant

a

loyal

companion”可知,“我”照顾小狗,收获了一个忠诚的伙伴。6.B

根据句中“at

the

door

when

I

returned”可知,“我”回家时,小狗会在家门口迎接“我”。7.A

根据上文“I

also

learned

that...”可知,“我”认识到在付出的同时自己也会受益,这就是“我”通过养狗学习到的一个经验,这个经验一直伴随着“我”的成长。ⅠⅡⅢ8.B

文章开头讲父亲特别讨厌狗,反对养狗,结合本段末“He

even

made

chew

toys

for

Chip

to

play

with.”可知,爸爸对小狗的态度转变了,缓和了对小狗的态度。9.A

根据上一段讲小狗在门口迎接主人归来,主人伤心时安慰主人,和本段中讲爸爸也喜欢上它,可推知,小狗讨人喜欢。10.C

下文“He

even

made

chew

toys

for

Chip

to

play

with.”说明爸爸也开始宠爱小狗,结合副词“even”可推知,爸爸是第一个让小狗坐沙发的人。11.C

根据句中“brought

us

together”和下文“instead

of

escaping

to

our

bedrooms

as

before”可知,小狗改变了所有人的习惯,让一家人聚在了一起。12.B

根据句中“review”可知,是复习以前学的把戏。ⅠⅡⅢ13.C

结合常识和句中“funny

stories

of

the

cute

things”可知,一家人在一起会讲小狗做的有趣的事,这是一种分享。14.D

不爱狗的人有时会抱怨那些把宠物太当人一样对待的爱狗人士。根据句中“People

who

are

not

dog

lovers”和“complain”可推知,不爱狗的人会抱怨爱狗人士把狗当人来对待。15.D

上文说不爱狗的人有时会抱怨爱狗人士把宠物太当人一样对待,结合句中“What

they

don’t

understand”可知,作者对此作出回应,说明原因:宠物激发了人性的美。ⅠⅡⅢⅢ.读后续写阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。Mostofusneverforgetthepersonthatwasthereforusinourdarkesttimes.Apparently,penguins(企鹅)don’teither.Onatypicalday,offthecoastofasmallBrazilianisland,JoaoPereiradeSouzaheadedoutfishing.Hewasdisheartenedtofindthatanoilleakhadpollutedthewaters.Staringoutattheoilywaves,hedecideditwasnotagooddaytofish.Butwalkingonthebeachthatday,hefoundastrugglingpenguin,coveredinoilandstarving.ⅠⅡⅢJoaotookthepenguinhome,andspentawholeweekgentlycleaningitandnursingitbacktohealth.HenameditDindim,aPortuguesewordmeaning“icepop”.DindimisaMagellanicpenguin,aspeciesknownforlivingintheseasofSouthAmerica.Inordertobreed(繁殖),theymustreturntoPatagonia,5,000milesfromJoao’shome.ⅠⅡⅢAfteraweekofrehabilitation(康复),JoaopatientlytookDindimbacktotheseaandtaughtithowtoswimagain.WhenDindimcouldswimquitewell,Joaotookitoutintotheseabyboatanddroppeditofftoencourageittoswimbacktoitshome.Butwhenhewasbacktoshore,hefoundthepenguinwaitingforhim.Joaomadetwomoreattemptslater,buteachtimethebirdwouldjustreturntoJoao’shome.ItseemedthatDindimhadalreadyformedafamilybondwithJoaoandwouldn’tleave.ⅠⅡⅢJoaohadnochoicebuttokeepthelittlecreature.Duringthefollowingmonths,DindimwouldfollowbehindJoaotofishonthecoastjoyfully.DindimalsolikedtolieonJoao’slap,lettingJoaogiveitshowers,allowingJoaotofeeditfishandtopickitup.JoaoandhisfamilyenjoyedthecompanyofDindim.ButdeepinsideJoao’sheart,heknewDindimbelongedtothewild.Gradually,thehotsummerdayswitnessedthechangeofitsnewfeathers.Wasittimetosay“goodbye”?注意:1.续写词数应为150个左右;2.请按如下格式作答。ⅠⅡⅢSuddenlyonemorning,JoaofoundDindimdisappeared.___________________________________________________________________________________________________________________________________________________________________________________________________________Afewmonthslater,Joaoheardsomefamiliarcriesinhisbackyard.__________________________________________________________________________________________________________________________________________________________________________________________________ⅠⅡⅢSuddenly
