    (课件网) Section B(第三、四课时) 1.inexpensive的用法。 inexpensive是形容词,意为“不昂贵的”,inexpensive是由词根expensive加上前缀in-构成的,其同义词为cheap,反义词为dear/expensive。 【拓展】英语中常见的否定前缀有: ①dis-表示“分开,分离; 不”。例如: like喜欢—dislike不喜欢 agree同意—disagree不同意 ②in-(im-, ir-)表示“不,无”。例如: correct正确的—incorrect 不正确的 possible可能的—impossible不可能的 polite礼貌的—impolite不礼貌的 regular规则的—irregular不规则的 ③un-表示“不,非”。例如: happy高兴的—unhappy不高兴的 healthy健康的—unhealthy不健康的 usual寻常的—unusual 不寻常的 kind 友善的—unkind 不友善的 friendly友好的—unfriendly不友好的 clear清楚的—unclear 不清楚的 crowded拥挤的—uncrowded 不拥挤的 comfortable舒服的—uncomfortable 不舒服的; 不舒适的 2.convenient的用法。 convenient是形容词,意为“便利的; 方便的”,其副词形式为conveniently,名词形式为convenience。convenient常用于“It is convenient for sb. to do sth.”这一句型,意为“对某人来说做……是方便的”。这一句型中it为形式主语,不可以说成“Sb. is convenient.”。例如: 如果方便请到我家坐坐。 正: Please come round to my home if it is convenient for you. 误: Please come round to my home when you are convenient. 3.These are similar requests for directions. 这些是类似的问路请求。 request意为 “要求; 请求”,既可作名词又可作动词。 (1)用作名词时,意为“要求; 请求”,是可数名词, 其后常接“for+n.”。例如: We should make a request for help.我们应该请求帮助。 (2)用作及物动词,意为“要求,请求”,其后可以跟名词、不定式的复合结构或从句作宾语。常见用法有: ①request sth. (from sb.)意为“(向某人)请求某事/某物”。例如: The boy requested some paper from me. 那男孩向我要了一些纸。 ②request sb. to do sth.意为“请求某人做某事”。例如: She requested me to draw a map for her.她请求我给她画张地图。 ③当其后接宾语从句时,从句谓语常用“should+动词原形”结构,should可省略。此时,其用法与suggest的用法相同。例如: I requested that they (should) finish the project on time. 我请求他们按时完成这项工程。 基础达标 一、根据汉语提示,写出正确的单词完成句子。 1.Excuse me, can you give me your e-mail _____(地址) I want to send you an e-mail. address 2._____(地铁) is a fast public transport.
