第十单元语法 第一课时 Section A Period 1 (1a — 2d) 语法 3A-4C * 语法重点一 “be supposed to”的用法 1. be supposed to意为“应该；被期望/期待; 理应”，用来表示根据规定人们不得不做某事，或期待发生某事，时态、人称和句式的变化在be上体现，to为不定式符号，后接动词原形。 2. be supposed to do的否定式，要在be后加not, 即be not supposed to do此时相当于be not allowed to do, 意为“不被许可；不应当”。 3. 如果表达“过去某时应该(不应该)做”时，用was (wasn’t) / were (weren’t) supposed to do, 相当于should (shouldn’t) have+动词过去分词。 be supposed to do sth. “应该做某事”, 某人被期望做某事， 主语通常是人, 相当于be expected to do sth.，常用来提出建议，其否定结构为be not supposed to do sth.。 You’re supposed to get there early. 你应该早点到那儿。 You’re not supposed to smoke here. 你们不应该在这里吸烟。 拓展: ★当be supposed to的主语为“物”时，意为“本应，本该”，表示某事本应该发生而没有发生。 The train was supposed to arrive ten minutes ago. 火车应该在十分钟前到达。 ★当be supposed to的主语是人时，后面还可以接“have + 过去分词”，意为“本应,应该”，表示本应该做某事而没做。 You are supposed to have arrived in Beijing now. 你本应该现在已经到了北京了。 be supposed to do sth为系表结构，强调客观上有责任/义务作某事。 You are supposed to clean the blackboard, for you are on duty today. should 强调主观上应该做某事。 You should study hard, for you are a student. be supposed to do sth. ＆ should的区别 ?语法重点二 greet v. 和…打招呼；迎接 She?greets?me whenever she meets me. ??她一见到我就打招呼。 Mick?greeted?her with a kiss on each cheek. 米克亲吻她的双颊以表问候。 The host?greeted?us at the gate. ?? 主人在大门口迎接我们。 greeting n. 问候；打招呼 He sends?greetings?to all the family. ?? 他发信向全家问候。 语法重点三 hold out my hand 伸出我的手 hold out 伸出； 坚持 She held out her hand to take the rope.?? 她伸手去抓那根绳子。 He laughed, holding out his cup for more tea.?? 他大笑，伸出杯子要给他再倒点茶。 Language points 1.
