Unit 6 Learning through Travel 例题解析 句型剖析(一) 　　1．Spending time in Canada with an English-speaking family has helped me to improve my speaking a lot. 　　spending time in…family在句中充当主语 　　【案例】______ how to raise the sails was really a hard job for the younger sailor. 　　　　A. Learn　　　　B. To learn　　　　 C. Learned　　　　D. Learning 　　解析：此题考查动词的ing形式用作主语。A、C两项不能作主语，而to learn表示将来，不合题意。故答案为D。 　　点评：动词的ing形式可以充当主语，其谓语动词应使用单数。有时可将其放在后面，句首用it来替代。例如： 　　Working with Mr. Lee is pleasant, for he is very easy-going. 　　和李先生共事很愉快，因为他是一个非常随和的人。 　　Taking a holiday in the country can help us a lot. 　　到乡下去度假对我们帮助很大。 　　It is no use trying to repair the ship. These holes are too large. 　　修这只船已经没有用了。这些洞太大了。 　　2．My friend and l have been eating lots of this as well. 　　have been doing句式 　　【案例】I ______ at the door for an hour．I think no's in. 　　　　A. knock　　　　　　　　　　　　B. am knocking 　　　　C. had knocked　　　　　　　　　 D. have been knocking 　　解析：此题的关键在于时间状语for an hour。A、B两项不能和此时间状语连用，而过去完成时不合此题，它表示在过去某个时间之前。所以答案为D，其表示一直在敲门而且现在还在敲门。 　　点评：（1）have been doing现在完成进行时。表示某种状态或行为始于过去，到现在已经持续了一段时间或仍在进行中。如： 　　CCTV has been broadcasting English programs ever since 1977. 　　CCTV自从1977年开始播放英语教学节目。 　　（2）as well“也，又”（和and连用，常置于句尾）。如： 　　I'm going to London and my sister's going as well. 　　我要去伦敦，我妹妹也要去。 　　He can climb trees and l can as well. 　　他会爬树，我也会。 　　as well as平行结构词。连接句中的各种句子成分。如： 　　He, as well as me, thinks you are right. 　　他和我都认为你是对的。 　　He was kind as well as sensible. 　　他既厚道又明白事理。 句型剖析(二) 1.Tomorrow I'm going to see St. Paul's Cathedral，which is supposed to be just magnificent. 　　be supposed to do结构 　　【案例】You ______ have helped that old man. That's our duty to help the old. 　　　　A. could　　　　　　　　　　　　 B. might 　　　　C. must　　　　　　　　　　　　　D. were supposed to 　　解析：此句意思为“你（过去）理应帮助老人”。而A、B、C三项均表示对过去情况的推测。所以答案为D。 　　点评：be supposed to do应该；理应 　　Everyone is supposed to bring a bottle to the party. 　　每个人都应带瓶酒来参加晚会。 　　You're supposed to tell them your decision as soon as possible. 　　你应该尽早地告诉他们你的决定。 　　be supposed to have done表示“本来应该做，
