《公共英语》练习及答案解析

    1.It’s still in the morning. There isn’t in the office.

    A. anyone B. everyone C. nobody D. any people

    答案：A.

    否定陈述句中用anybody或anyone，肯定陈述句中用some，somebody， someone。

    2. is not known that they discussed in the meeting.

    A. That B. He C. This D. It

    答案：D．

    it为形式主语。真正的主语是what从句。真正主语过长，会有头重脚轻的感觉，因此使用形式主语放在主语的位置，以显得句子“重量”均衡。

    3.The best news broke her and she has been gloomy ever since.

    A. feelings B. emotions C. mind D. heart

    答案：D．

    break one’s heart表使…伤心（心碎）。Feelings是感情，感觉；emotions表情绪。Mind心志，介意。

    4.He is much of a gentleman to fight.

    A. so B. as C. very D. too

    答案：D．

    too…to…固定搭配，表示太…以至于不…。本句意为，他是个绝对的绅士，不会动手打架的。

    5.Not until this term to realize how important this subject is to his future career as a diplomat.

    A. he began B. did he begin C. he has begun D. that he has begun

    答案：C.

    表示否定的副词前置句首，句子需要不完全倒装，即助动词提前。其余选项均可排除。

    6.who would like to go on the trip should put their names on the list.

    A. Those B. These C. Somebody D. The ones

    答案：A．

    who引导的定语从句的先行词一定是人，而ones一般指代物，不指代人。因此可以排除D。定语从句中提到了物主代词their names是复数，因此，先行词应该为复数。C可以排除。因此选A。

    7.A bottle weights less after air is taken out, proves that air has weight.

    A. we B. it C. which D. what

    答案：C．

    非限制性定语从句要用关系代词which。非限制性定语从句用于补充说明前一句话。

    8.How long ?

    A. you suppose did it last B. do you suppose it last

    C. did you suppose it last D. you suppose it last

    答案：B．

    do you suppose/think句的时态变化在后面的宾语从句，而不在主句，因此do you suppose不需要变化。
