单独成册对应学生用书第227页

Ⅰ.单项填空(建议用时8′)

1．I’d appreciate ________ if you could let me know in advance whether or not you will come.

A．it B．you

C．one D．this

解析：考查代词。I’d appreciate it if/when/that...是固定句式，it作形式宾语，故选A项。

答案：A

2．The agreements，________ from culture and education to special training programs，will play a key role in the China-Latin America partnership.

A．ranged B．having ranged

C．ranging D．to range

解析：句意为：这些协议，从文教到特殊培训项目，将对中国和拉美之间的伙伴关系起到一个关键作用。分析句子结构可知，空缺处要填非谓语动词，the agreements和range之间是主谓关系，要用现在分词作定语，故选C。

答案：C

3．My uncle hasn’t been able to quit smoking，but at least he has ________.

A．cut out B．cut down

C．cut up D．cut off

解析：句意为：我的叔叔没能戒掉吸烟，但是至少他抽得少了。cut out删除；cut down 减少；cut up切碎；cut off切断。所以选B。

答案：B

4．Food supplies in the flood-stricken area ________.We must act immediately before there’s none left.

A．have run out B．are running out

C．have been run out D．are being run out

解析：句意为：洪灾区的食物供应将要用光了，我们必须在用完之前立即采取行动。由句中“before there’s none left”可知食物还没有用完，只是将要用完，故可排除表“已用完”的A项；而run out本身含有被动意义，排除C、D两项，故选B项表“即将耗尽”。

答案：B

5．She has already tried her best.Please don’t be too ________ about her job.

A．special B．responsible

C．unusual D．particular

解析：句意为：她已经尽力了，请不要过分挑剔她的工作。be particular about...对……苛求、挑剔，是固定结构。所以答案选D。

答案：D

6．It is important to pay your electricity bill on time，as late payments may affect your ________.

A．condition B．income

C．credit D．status

解析：句意为：准时付电费很重要，因为付晚了会影响你的信用。condition条件；income 收入；credit学分，信用；status地位，状态。

答案：C

7．It took Mary quite a long time to ________ a new dress at the store.

A．pick up B．pick out

C．work out D．take up

解析：表示“挑选”之意，用pick out。pick up捡起；work out算出来；take up占有。

答案：B

8．________ in painting，John didn’t notice evening approaching.

A．To absorb B．To be absorbed

C．Absorbed D．Absorbing

解析：考查非谓语动词。句意为：由于专心于绘画，约翰没有注意到夜幕正在降临。此处的Absorbed in painting相当于原因状语从句Because he was absorbed in painting的省略。

答案：C

9．There’s a note pinned to the door ________ when the shop will open again.

A．saying B．says

C．said D．having said

解析：考查非谓语动词。分析句子结构可知句中已经有了谓语动词is，故首先排除B 项says。A项saying表示主动；C项said表示被动；D项having said表示动作先于is的动作发生。从逻辑关系上看，note与say之间是主动关系，所以选A项，在此用现在分词结构作后置定语。

答案：A

10．Our class held a fierce ________ as to whether to reduce the amount of homework or not.

A．bargain B．contest

C．debate D．campaign

解析：句意为：我们班对是否减少作业数量举行了激烈的辩论。debate辩论，争论，讨论；bargain讨价还价，议价；contest竞赛，争夺；campaign运动，活动；战役。

答案：C

11．He ________ as a national hero for winning the first gold medal for his country in the Olympics.

A．regarded B．was regarded

C．has regarded D．had been regarded

解析：句子主语和regard之间为被动关系，且是发生在过去的动作，故用一般过去时的被动语态。故选B项。

答案：B

12．—Jim，can you work this Sunday?

—________？I’ve been working for two weeks on end.

A．Why me B．Why not

C．What if D．So what

解析：考查情景交际。句意为：——吉姆，这个星期天你能工作吗？——为什么是我？我已经连续工作两个星期了。Why me为什么是我；Why not为什么不；What if如果……将会怎样；So what那又怎样；Why me是“Why do you ask me to work this Sunday”的省略。

答案：A

13．The research project has only been ________ way for three months，so it’s too early to evaluate its success.

A．under B．on

C．in D．by

解析：句意为：这个研究项目仅仅进行了三个月，所以要对它的成绩作出评价为时尚早。under way表示“在进行之中”，符合句意。故选A项。
