It has been warned that        to the surroundings with people infected by Covid-19 without any

protection can lead to severe result.

being exposed

exposed

having exposed

to expose

考查非谓语动词。句意：有人警告称，在没有任何保护措施的情况下，暴露在有感染 Covid-19的人环境中会导致严重的结果。分析句子结构可知expose在句中应用非谓语动词形式，表示“暴露”短语为be exposed to,且从句中缺少主语，expose 与主语people是被动关系，故应用动名词的被动式作主语。故选A项。

It is said that railway station is now         large as What it was.

as twice

twice as

twice much

much twice

考查倍数表达法。句意：据说火车站现在是原来的两倍大。倍数的基本结构一般为“A+倍数+as+形容词或副词的原级+as+B”，表示“A正好是B的多少倍”。联系下文large as，此处用twice as large as 表示“是.....的两倍大”。故选B项。

You must have had some moments when you were disappointed. If so, how           you deal with them?

will

did

can

do

考查动词的时态和语态。句意：你一定有过失望的时候。如果有，你是怎么处理的？must have done 表示对过去的事情的推测。可知时态为一般过去时。在特殊疑问句中助动词应用did。故选B项。

---Miss Yuan，you promised！

---Well，______.But it was you broke your word first.

so was I

so did I

so I was

so I did

考查强调句。句意：袁女士，你承诺过的！噢，我确实如此。但是是你先失言的。A和B是一类回答，C和D是一类回答。当别人说他自己怎么样，而你有跟他同样的情况时，用AB这样的形式回答。当别人说你怎么样，而你自己也确实是他说的那样时，用CD回答。至于用be动词还是do要根据具体语句定，谓语是be时就用be的相应形式，谓语是实意动词时就用do的相应形式。根据句意，故选D。

Every evening after dinner, if not ________ from work, I will spend some time walking my dog.

being tired

tiring

tired

to be tired

考查省略句。当状语从句的主语和主句主语一致，且状语从句中有be动词的时候，可以把状语从句的主语和be动词一起省略，本题if后面省略了I am，句意：每天晚上吃完晚饭以后，如果不是很累，我就会花点时间来遛狗。故C正确。

I don’t want to be       else. I just want to be       .

anybody;myself

somebody;myself

everybody;me

anybody;me

考查代词。句意：我不想成为任何人，我只想做我自己。anybody 任何人，用在否定句和疑问句中；somebody某人，用在肯定句中；everybody每个人；由don’t可以判断此句是否定句，所以用anybody，表示任何人。第二个句子根据I为主语，可知用反身代词myself 我自己，根据句子意为我要做我自己，me是宾格，作宾语。故选A项。

Based on the agreement,all payments          be made by the end of the month.

may

can

shall

will

考查情态动词。句意：根据协议，所有款项应在月底付清。shall用于法律，条款中表示必须要做的事。故选C项。

Mary never does any reading in the evening, ______.

so does John 

John does too

John does not to

neither does John

主句用never，后面的倒装句相应的用nor或者neither，用完全倒装形式表示后者与前者情况相似。
