2、bited 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 hadnt enough money and _ to borrow from his father, he decided to sell his watch. A. not wanted B. not
3、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.

4、 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 delivere
5、d 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
6、 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 countrys 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 countrys c
7、hief 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 wasnt 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
8、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descriptio
9、ns 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
10、要用分词作非谓语。排除CD。又因为关系是被动因此选B。 4. How many of us _, say, a meeting that is irrelevant to us would be interested in the discussion? A. attended B. attending C. to attend D. have attended 解析：参加一个对我们不重要的会议，有多少人会对它感兴趣呢？这里选attending是因为“attending a meeting that is not important to us”这整句话作“us”的定语，而A attened表
11、示一个动作，不能作定语，C和D分别表示将要和完成，都是作谓语，语法上不通，且句意上也不顺，更不能选了。 5.If an earthquake occurred, some of the one-story houses _. A. might be standing left B. might be left standing C. might leave to be standing D. might be left to stand 解析：might be left 是主句中被动语态的谓语动词部分，而现在分词的standing作了主语one-storey houses的主语补足语，表示主动和进行的意义。
