33. -Mary is sure to win the prize in the contest.

-I agree, she ______ so hard for months.

A. was working　　　 B. worked

C. is working　　　　 D. has been working

[解析]选D。考查时态。由第一句可知竞赛还没有举行。因此玛丽勤奋学习的动作是从几个月前开始，持续了几个月，还要进行下去，故用现在完成进行时。

32. Don’t worry about him. We can depend on _____ he has a gift for driving.

A. that　　　　　 B. it　　　　 C. what　 D. it that

[解析]选D。在depend on后如有that引导的宾语从句，要在从句前加上it然后再接that从句。

[讲台挥洒一刻]

it作形式宾语时，除了在动词+宾语+宾语补足语这一结构中，如果宾语太长可用“动词+it+宾语补足语+宾语”以外，还可用于：

(1)不能直接跟宾语从句的动词后面，尤其是表示好恶的动词后面，如enjoy, like, hate, love, dislike, prefer, see to, depend on, appreciate, don’t mind等。而宾语从句则紧跟it之后。

①You may depend on it that he will turn up in time.

你可以信赖他会及时到来的。

②I’ll see to it that all these letters will be sent to the post office before twelve.

我将负责所有信件十二点以前被送到邮局。

③She won’t like it if you arrive late.

她不喜欢你来迟了。

④He hates it when people use his bike.

　他讨厌人们用他的自行车。

(2)用于have it that(说，认为)，take it that(认为)等固定表达中：

⑤I take it that you agree.

我认为你同意了。

⑥Report had it that A(H1N1) flu spread widely across the globe.

据报道甲型H1N1流感全球迅速蔓延。

30. ______ benefit from the tour, they narrowly escaped from being buried in the earthquake.

A. Rather than　　　　　　　　 B. Far from

C. Other than　　　　　　　　　 D. More than

[解析]选A。考查副词短语辨析。rather than而不是，与其说……倒不如说。far from远非；other than 除了；more than不仅仅。句意为：他们没有从这次旅行中受益，反而险些被地震埋葬了。

29. He didn’t make ________ clear whether the meeting would be held.

A. this　　　　　　 B. that　　　　　　　 C. it　　　　　　 D. these

[解析]选C。考查代词。代词it在句中作形式宾语，常用于“宾语从句+宾语补足语”结构中，构成“动词 + it + 宾语补足语+ 宾语从句”的句式。

28. In the history of Chinese revolutionary, Taierzhuang Battle was a _______ battle in which both sides suffered heavy losses.

A. fierce　　　　　 B. strong　　　　　 C. hot　　　　　　　 D. peaceful

[解析]选A。考查形容词词义辨析。句意：在中国革命史上，台儿庄战役是一场双方都损失惨重的激烈的战斗。strong表示“强壮的”; hot表示“因火热而激烈的”，均不用于形容战争。D项不合句意。

27. Polly found herself _______ up at a man standing with his hand resting on her arm.

A. stared　　　　　　 B. stare　　　　　　 C. staring　　　　　　　 D. to stare

[解析]选C。考查非谓语动词。题中的herself和stare是主动关系，而且stare的动作正在进行。因此用staring。

[举一反三]

In the reading room, she found herself _______ at by a stranger, which made her a little nervous.

A. stared　　　　　 B. stare　　　　　 C. staring　　　　　 D. to stare

[解析]选A。herself和stare at是动宾关系，即她发现一个陌生人盯着自己/自己被一个陌生人盯着。故用过去分词表被动。

26. The hours of hard work _______ when he became the champion of the game.

A. paid for　　　　　　 B. paid off

C. paid back　　　　　 D. paid up

[解析]选B。考查短语动词。pay for. . . “为……付钱”；pay off “还清债务，得到好的结果，得到回报”；pay back“偿还(借款)”；pay up“交清，付清”。句意为：当他得了比赛冠军时，数小时的艰苦工作得到了回报。
