现在分词课件习题答案及详解

1. It’s easy to blame the decline of conversation on the pace of modern life and on the vague changes ______ place in our ever-changing world.

A. taking

B. to take

C. take

D. taken

2.While ____ the sun, the satellite has sent more than four billion bits of information back to earth.

A. having orbited

B. being orbited

C. having been orbited

D. orbiting

解析：答案选D.本题考查现在分词做状语。动词orbit和主语the satellite是主

动关系，主动关系的话要选现在分词做状语，所以排除B和C；然后看A和D,A 是完成式，只有在主句是过去时的时候，状语中的非谓语动词才要用分词的完成式。

3.Realizing that he hadn’t enough money and _____ to borrow from his father, he decided to sell his watch.

A. not wanted

B. not to want

C. not wanting

D. wanting not

解析：and 前后连接的两个句子结构平行，所以realize应该和want 一样使用现在分词形式。而且分词的否定是在前面+not所以选C。

4.The computer works very fast, ____ data at the speed of light.

A. having handled

B. handling

C. handled

D. handles

解析：现在分词表示主动，且表示状态。

5.He noticed the helicopter hovering over the field. Then to his astonishment, he saw a rope ladder ____ out and three men climbing. A. throwing B. being thrown

C. having thrown

D. having been thrown

解析：考察的是see sb doing结构以及被动语态a rope ladder是被认出来的所以排除AC。因为绳梯被认出来与三个男人在攀爬时间几乎一致，因此选B。

6.The speech _____, a lively conversation started.

A. being delivered

B. was delivered

C. be delivered

D. having been delivered

解析：考察独立主格，演讲先结束，讨论才开始。因此用现在分词的完成被动式。句中没有并列连词，所以不能选B。

7.There ____ nothing more for discussion, the meeting came to an end half an hour earlier.

A.to be

B. to have been

C. being

D. Be

8.Time _____, the celebration will be held as scheduled.

A. permit

B. permitting

C. permitted

D. Permits

解析：Time permitting独立结构作条件状语=If time permits，把time 看做逻辑主语，用permitting表示主动。C表示被动，A，D是做谓语，根据主语的单复数定，同时还要有连词when ,if等

9.Agriculture is the country’s chief source of wealth, wheat ____ by far the biggest cereal crop.

A. is

B. been

C. be

D. Being

解析：因为前半句Agriculture is the country’s chief source of wealth 已经是个完整的句子，而后面又没有连词，所以不可能再出现动词，排除A和C，而B没有这种用法，正确的独立主格表示完成时的结构应该是having been，所以B错。

Exercise

1. He wasn’t asked to take on the chairmanship of the society, ____ insufficiently popular with all members.

A. being considered

B. considering

C. to be considered

D. having considered

解析：现在分词作状语，此句用的是被动形式。现在分词在句中作状语，修饰谓语动词或整个句子，表示动作发生的原因，结果，时间，方式，条件等。此句是表原因。

2. The article opens and closes with descriptions of two news reports, each ____ one major point in contrast with the other.

A. makes

B. made

C. is to make

D. making

解析：因为一个英文句子中只能有一个谓语，所以只能选择答案中不是谓语的，

故排除A, C。叙述的观点是相反的，修饰成分descriptions of two news reports与被修饰成分each____one major point in contrast with the other之间的关系是主动的，所以用表示主动关系的ING形式，不用表示过去、完成的made。

3. All flights ___ because of the storm, they decided to take the train.

A. having canceled

B. having been canceled

C. were canceled

D. have been canceled

解析：考察独立主格，一个句子只能有一个谓语动词，因此逗号前面
