(2)Weve had a good start, but next, more work needs________ (do) to achieve the final success. 答案：doing/to be done　考查情态动词的用法。need既可用作情态动词也可用作实义动词，在本句中用作实义动词；need后可接动名词的主动式表被动含义，也可接不定式的被动语态。 (3)We ________ bought so much food now that Suzie wont be with us for dinner. 答案：neednt have　考查情态动词。句意：既然Suzie不和我们一起吃饭，那么我们本不必买那么多食物。neednt have done本不必做……。 (4)Its quite warm here; we________ turn the heating on yet. 答案：neednt　本题考查情态动词的用法。句意：这儿非常暖和；我们不必开暖气。neednt不必。 (5)—Must we do it now? —No, you ________. 答案：neednt　回答由must引起的问句时，否定回答一般用neednt。 (6)—Need you go by yourself? —Yes, I________. After all, they are all fresh. 答案：must　此处为肯定回答：是的，我必须去。毕竟，他们都是生手/新人(还干不了)。 (7)—Well, I forgot to bring your dictionary here yesterday. —Actually you ________ (bring)it here. You were not allowed to use it. 答案：didnt need to bring　意为“你昨天不必带词典来”。neednt have brought是“本不必带而带来了”，不合题意。 巩 固 提 升 Ⅰ.完成句子(用didnt need to do，neednt have done，neednt do的形式) 1．这次旅行中我穿得很暖和，但我本没有必要穿这么暖和。天气很热。 I dressed very warmly for the trip，but I______________.It was very hot. 2．我本不需要带那么多食物的，因为他们免费提供我们一切。 I______________________so much food because they offered us everything for free. 3．你不必浇这些花，因为天就要下雨了。 You__________________the flowers because it is going to rain. 4．你不需要哭。你需要的是战胜自己。 You__________________.You need to overcome yourself. 5．当时我不必去银行——我找玛丽借了点儿钱。 I__________________then—I borrowed some money from Mary. 6．我不需要买那本词典，因为我妈妈已经为我买了一本了。 I____________________that dictionary because my mother had bought one for me. 7．虽然你不需要去上学，但是你不能打游戏。 Though you______________________，you mustnt play games. 8．我本来不需要给他打电话的。 I__________________________a call to him. 答案：1.neednt have done so　2.neednt have carried 3．neednt water　4.neednt cry 5．didnt need to go to the bank 6．didnt need to buy 7．neednt/dont need to go to school 8．neednt have made Ⅱ.句型转换 1．Thank you for buying the gift for me, but it wasnt necessary. →You____________________the gift for me. 2．There was no need for you to write the letter to Tom. →You____________________the
