A．单句填空
1．To my delight, I________(choose) from hundreds of applicants to attend the opening ceremony.
答案 was chosen [句意：令我高兴的是，在几百个申请者中我被选中参加开幕式了。首先，句子主语I和choose是被动关系，所以要用被动语态；其次，本句是对过去所发生事情的客观描述，所以用一般过去时，故用was chosen。]
2．It is reported that a space station________(build) on the moon in years to come.
答案 will be built [句意：据报道在未来的几年里(人们)将在月球上建立空间站。根据分析可知，a space station与build之间是被动关系，又由in years to come“在未来的几年里”可知，用一般将来时，故用will be built。]
3．More expressways________ (build) in Sichuan soon to promote the local economy.
答案 will be built [句意：四川将很快修建更多的高速公路以促进地方经济(的发展)。题干中的soon表明空格处用一般将来时，且句子的主语expressways 是谓语动词build的承受者，故用一般将来时的被动语态will be built。]
4．The professor was delighted to find that two thirds of the project________(finish) by the students independently.
答案 had been finished [句意：教授高兴地发现学生们已独立完成了该项目的三分之二。根据分析可知，finish这个动作发生在was delighted to find之前，应该用过去完成时，又因project和finish之间是被动关系，故用had been finished。]
5．Unless some extra money________(find)，the theatre will close.
答案 is found [句意：除非我们能再弄到些钱，否则剧院将关闭。主句用一般将来时，从句用一般现在时表示将来，money和find之间为被动关系，故用被动语态。]
6．—What's up? The house is in a mess.
—Oh, I forgot to tell you. It________(paint)．
答案 is being painted [句意：——怎么回事？屋子里乱糟糟的。——哦，我忘了告诉你，房子正在被粉刷。此处表示说话时正在进行的动作，故用现在进行时的被动语态，表示“正在被粉刷”。]
7．“Remember to put on more clothes，” Mother said on the phone. “Cold weather ________ (expect) to come tomorrow morning.”
答案 is expected [句意：妈妈在电话中说：“记得多穿点衣服，寒冷天气预计明天早晨就到了。”根据句意可知“预计”这一行为发生在直接引语语境中的“现在”，故用一般现在时；cold weather与expect为被动关系，故用被动语态。]
8．—Excuse me, is the book Gone with the Wind by Margaret Mitchell available now?
—Sorry, but it ________ (sell) so well that we don't have any in store.
答案 sells [句意：——玛格丽特·米切尔写的《飘》现在有现货吗？——对不起，它这么畅销，我们没有任何存货了。sell在此处意为“卖得……”，sell well表示“畅销”不用被动语态。]
9．—That must have been a terrible experience.
—Yeah. I ________ (stick) in the damaged car, unable to move.
答案 was stuck [句意：——那一定是一次可怕的经历。——是的。当时我被卡在破损的车里动不了。考查一般过去时的被动语态。]
10．This brand of knife is quite popular with customers, for it ________ (cut) well.
答案 cuts [句意：因为这个品牌的刀子很好用，所以它在顾客中很受欢迎。本句表示主语的某种属性特征，故用一般现在时的主动形式表示被动意义，此外主语it为单数第三人称，故cut后需加“s”。]
