2、orbitedc. having been orbited d. orbiting解析：答案選d.本題考查現(xiàn)在分詞做狀語。動(dòng)詞orbit和主語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，所以排除b和c；然后看a和d,a是完成式，只有在主句是過去時(shí)的時(shí)候，狀語中的非謂語動(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 wanti

3、ng 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。而且分詞的否定是在前面+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. then to his astonishment, he saw

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)語態(tài)a rope ladder是被認(rèn)出來的所以排除ac。因?yàn)槔K梯被認(rèn)出來與三個(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 b

5、een delivered解析：考察獨(dú)立主格，演講先結(jié)束，討論才開始。因此用現(xiàn)在分詞的完成被動(dòng)式。句中沒有并列連詞，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 pe

6、rmitting獨(dú)立結(jié)構(gòu)作條件狀語=if time permits，把time看做邏輯主語，用permitting表示主動(dòng)。c表示被動(dòng)， a，d是做謂語，根據(jù)主語的單復(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)榍鞍刖鋋griculture is the countrys chief source of wealth 已經(jīng)是個(gè)完整的句子，而后面又沒有

7、連詞，所以不可能再出現(xiàn)動(dòng)詞，排除a和c，而b沒有這種用法，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，此句用的是被動(dòng)形式?，F(xiàn)在分詞在句中作狀語，修飾謂語動(dòng)詞或整個(gè)句子，表示動(dòng)作發(fā)

8、生的原因，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，所以只能選擇答案中不是謂語的，故排除a, c。敘述的觀點(diǎn)是相反的，修飾成分descriptions of two news reports與被修飾成分each_one major poi

9、nt 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，不用表示過去、完成的made。3. all flights _ because of the storm, they decided to take the train.a. having canceled b. having been canceledc. were canceled d. have been canceled解析：考察獨(dú)立主格，一個(gè)句子只能有一個(gè)謂語動(dòng)詞，因此逗號(hào)前面要用分詞作非謂語。排除cd。又因?yàn)殛P(guān)系是被動(dòng)因此選b。4. how many of us _, sa

10、y, 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，而a attened表示一個(gè)動(dòng)作，不能作定語，c和d分別表示將要和完成，都是作謂語，語法上不通，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. mi
