Language Points ① What are they used for?（教材P42） be used for sth. / doing sth. 意为“被用来做某事”，表示用途或目的，后接名词或动名词，相当于be used to do sth. e.g. Clothes are used for keeping (= to keep) warm. 衣服被用来保暖。 Wood can be used for building (= to build) houses. 木材可以被用来建造房屋。 — Can you help me think of an invention? — With pleasure! （教材P42） With pleasure也可说成It’s a / my pleasure.或 A pleasure.意思是 “我的荣幸；愿为你效劳；这是件愉快的事”。 e.g. — Will you please help me take the books to the classroom? 请你帮我把这些书带到教室里去好吗？ — With pleasure. / It’s a pleasure. 愿意为你效劳。 pleasure​ n. 愉快；高兴 e.g. I will remember this meeting with pleasure. 我会愉快地记着这次的会晤。 It is a pleasure to work with you. 和你一起工作很愉快。 Well, you do seem to have a point … （教材P42） 1. you do seem to have a point ... 是个强调句，用“助动词do + 谓语动词原形”的结构。 e.g. Do stay for supper! 一定要留下吃晚饭! He did come here yesterday. 他昨天的确来这儿了。 Do come to my birthday party. 一定要来我的生日聚会。 2. have a point 有道理 e.g. I guess you have a point there. 我想你说的有道理。 Strangely, both of them may have a point. 奇怪的是, 两个人似乎都有道理。 For example, it mentioned that the zipper was invented by Whitcomb Judson in 1893. （教材P42） 1. mention表示“提到；提及”，是及物动词，其后接名词或 代词作宾语时，无需用任何介词；另外注意不接双宾语。如： e.g. Don’t mention this problem this evening. 今晚别提这个问题。 Nobody mentioned the time of this meeting. 谁也没有提到这次会议的时间。 2. 若后接动词，要用动名词，不能用不定式。 e.g. Whenever I mention playing football, he says he’ s too busy. 我一提起踢足球，他就说太忙。 3. 口语中说Don’ t mention it. 主要用来回答感谢，有时也用来回答道歉。如： e.g. A: Thank you very much. 非常感谢。 B: Don’ t mention it. 不客气。 Homework Homework 完成《金》Period 1 Thank you! null 70477.43 null 68674.805 null 70555.805 $$
