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。動詞orbit和主語the satellite是主動關(guān)系，主動關(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的時候，狀語中的非謂語動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

7、詞，所以不可能再出現(xiàn)動詞，排除A和C，而B沒有這種用法，正確的獨立主格表示完成時的結(jié)構(gòu)應該是 having been，所以B錯。Exercise1.

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