3⁠lostthewallet？Letmefinditout(弄明白).(

C

)1.A.atB．ofC．in1．C

it指的是前文提到的wallet，所以应该是在钱包里面。C(

B

)2.A.soB．andC．or2．B句意：一张是约瑟夫的，另一张是伊曼纽尔的。空处前后为并列关系，用and连接。(

B

)3.A.WhatB．WhoC．How3．B结合语境这里是问谁丢了钱包，用who提问。BBAnotebookisnextto

4⁠wallet.Iopenitand

5⁠，

“Gototheschoolbaseballgameat2：30.”MaybeIcanfindoutwhose(谁的)walletitisatthegame.(

)4.A.aB．anC．the4．C此处是特指前文提到的钱包，所以要用定冠词the。(

A

)5.A.seeB．seesC．amseeing5．A

and前的open和此处的动词并列，所以都用原形。CAIwalktosomegirlsonthecourt(球场).“

excuseme打扰一下，本句是祈使句，excuse要用动词原形。(

B

)7.A.sayB．saysC．issaying7．B主语是oneofthem，所以谓语动词要用第三人称单数。(

B

)8.A.heB．hisC．him8．B根据后文he可知此处应该是his。ABB“No，”Joseph's

9⁠says.“HisbrotherEmmanuellosthiswallet.Andtheirtickets(票)areinit,

C

)9.A.friend's

B．friends'

C．friend(

A
