黑龙江省宁安市东京城林业局第三中学高中英语 Module 1 Small Talk Vocabulay Grammar 学案 外研版选修 6学习目标:学习和区别 didn’t need to do 和 needn’t have done 的用法,提高语言运用能力。学习方法指导:通过复习知识点,高考链接的训练对该语法进行巩固和熟练应用。学习过程:Ⅰ.1. 本模块提到了 need 表示“过去不必做某事”的表达方法。didn’t need to do 和 needn’t have done 这两种结构都可以表示过去不必做某事, 但 didn’t need to do 表示“没必要, 实际上也没有做某事”;而 needn’t have done 则表示“本没有必要, 但实际上已经做了某事”。比较: ①They didn’t need to do it themselves, so they went home in advance. ②They did not need to go to school, so they went camping together. ③I didn’t need to get up early this morning, so I stayed in bed until 9 a. m. 上面三句话中, ① 表明他们没必要自己做, 实际上他们也没有自己做; ② 表明我们没有去上课; ③ 表明实际上“我”没有早起。 ①As it turned out to be a small house party, we needn’t have dressed up so formally. ②—Mr. Smith didn’t come last night, did he? —No. We needn’t have waited for him.

The hedges needn’t be trimmed this week. 本周树蓠不必要整修。2)“need”作为实义动词时, 通常用法是: ① 人+need+to do We need to collect the parcel before we leave for England. ② 物+need+doing The flowers need watering. ③ 物+need +to be done His leather shoes needs to b...
