2、rbitedC. having been orbited D. orbiting解析：答案選D.此題考查現(xiàn)在分詞做狀語(yǔ)。動(dòng)詞orbit和主語(yǔ)the satellite是主動(dòng)關(guān)系，主動(dòng)關(guān)系的話要選現(xiàn)在分詞做狀語(yǔ)，所以排除B和C；然后看A和D,A是完成式，只有在主句是過(guò)去時(shí)的時(shí)候，狀語(yǔ)中的非謂語(yǔ)動(dòng)詞才要用分詞的完成式。3.Realizing that he hadnt enough money and _ to borrow from his father, he decided to sell his watch.A. not wanted B. not to wantC. not wantin

3、g D. wanting not解析：and 前后連接的兩個(gè)句子結(jié)構(gòu)平行，所以realize應(yīng)該和want一樣使用現(xiàn)在分詞形式。而且分詞的否認(rèn)是在前面+not所以選C。4.The computer works very fast, _ data at the speed of light.A. having handled B. handling C. handled D. handles解析：現(xiàn)在分詞表示主動(dòng)，且表示狀態(tài)。5.He noticed the helicopter hovering over the field.

4、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結(jié)構(gòu)以及被動(dòng)語(yǔ)態(tài)a rope ladder是被認(rèn)出來(lái)的所以排除AC。因?yàn)槔K梯被認(rèn)出來(lái)與三個(gè)男人在攀爬時(shí)間幾乎一致，因此選B。6.The speech _, a lively conversation started.A. being delivered B. was deliveredC. be delivered D. having be

5、en delivered解析：考察獨(dú)立主格，演講先結(jié)束，討論才開(kāi)始。因此用現(xiàn)在分詞的完成被動(dòng)式。句中沒(méi)有并列連詞，所以不能選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. Be8.Time _, the celebration will be held as scheduled.A. permit B. permitting C. permitted D. Permits解析：Time per

6、mitting獨(dú)立結(jié)構(gòu)作條件狀語(yǔ)=If time permits，把time看做邏輯主語(yǔ)，用permitting表示主動(dòng)。C表示被動(dòng)， A，D是做謂語(yǔ)，根據(jù)主語(yǔ)的單復(fù)數(shù)定， 同時(shí)還要有連詞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?yàn)榍鞍刖銩griculture is the countrys chief source of wealth 已經(jīng)是個(gè)完整的句子，而后面又沒(méi)有連

7、詞，所以不可能再出現(xiàn)動(dòng)詞，排除A和C，而B(niǎo)沒(méi)有這種用法，正確的獨(dú)立主格表示完成時(shí)的結(jié)構(gòu)應(yīng)該是 having been，所以B錯(cuò)。Exercise1. He wasnt asked to take on the chairmanship of the society, _ insufficiently popular with all members.A. being considered B. consideringC. to be considered D. having considered解析：現(xiàn)在分詞作狀語(yǔ)，此句用的是被動(dòng)形式?，F(xiàn)在分詞在句中作狀語(yǔ)，修飾謂語(yǔ)動(dòng)詞或整個(gè)句子，表示動(dòng)作發(fā)生

8、的原因，結(jié)果，時(shí)間，方式，條件等。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?yàn)橐粋€(gè)英文句子中只能有一個(gè)謂語(yǔ)，所以只能選擇答案中不是謂語(yǔ)的，故排除A, C。表達(dá)的觀點(diǎn)是相反的，修飾成分descriptions of two news reports與被修飾成分each_one major poin

9、t in contrast with the other之間的關(guān)系是主動(dòng)的，所以用表示主動(dòng)關(guān)系的ING形式，不用表示過(guò)去、完成的made。3.

10、, 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：參加一個(gè)對(duì)我們不重要的會(huì)議，有多少人會(huì)對(duì)它感興趣呢？這里選attending是因?yàn)椤癮ttending a meeting that is not important to us這整句話作“us的定語(yǔ)，而A attened表示一個(gè)動(dòng)作，不能作定語(yǔ)，C和D分別表示將要和完成，都是作謂語(yǔ)，語(yǔ)法上不通，且句意上也不順，更不能選了。5.If an earthquake occurred, some of the one-story houses _.A. might be standing leftB.
