　　Section I 课前准备、听力、口语

　　1. What are the biggest problems facing the earth? 地球面临着的最大问题是什么? (p. 65 Warming Up Ex.1)

　　1) 现在分词短语facing the earth在句中作定语，相当于定语从句that face the earth. face此处用作及物动词，意为"面向，朝"，作此义也可用作不及物动词，常和介词to，toward或on连用。如： ① She turned to face the newcomer and introduced herself. 她转过身来面对新来者作了自我介绍。 ② The building faces the park. 那座建筑物面对着公园。③ The window faces on the street.窗户面对着衔道。 ④ -- How does this house face? --It faces to the east. -- 这座房屋面朝哪边? -- 朝向东边。

　　【拓展】 face还可意为"面对／临(问题或不愉快的情况)"。如：① Manufacturing industry faces a grim future if the government pursues its present policies. 如果政府继续推行现行政策，制造工业就会面临严酷的未来。② He couldn't face his boss after marking such a fool of himself at the meeting. 他在会上做出了这样的丑事之后，不敢面对自己的老板。

　　2. Why is she giving this speech? 她为什么发表演讲呢? (p. 66 Listening Part 1 No.1)

　　speech此处意为"演说，演讲"，常用作单数形式，"发表演说"多用动词give，make，deliver等与之搭配。如：① I had to give a speech to the Press Club. 我不得不向记者俱乐部发表演说。② He delivered a speech in English on world-peace. 他用英语发表了一篇关于世界和平的演说。

　　【拓展】speech 作"说话能力；言论；口音"讲，是不可数名词。如：① Only human beings are capable of speech. 只有人类才具有说话能力。 ② The illness deprived her of the power of speech. 她因病失去了说话能力。 ③ Speech is silver, silence is golden. (谚)雄辩是银，沉默是金。④ His speech shows that he's from Sichuan. 一听他的口音就知道他是四川人。

　　3. What do you think she will say next? 你认为她下步讲什么呢? (p. 66 Listening Part 1 No.4)

　　1) 本句为双重问句。双重问句有两种形式：

　　(1)一般疑问句型双重问句：本结构属于一般疑问句，主句谓语动词常是ask (询问)，tell (告诉)，know (知道)，realize (意识到)，make sure (确信)等，宾语由特殊疑问词引导的宾语从句充当。如：① Do you know why we can't be allowed to smoke here? ② Can you still remember when we visited the Great Wall last year? ③ Have you told him how we are going to the cinema? ④ Do you realize how serious the problem is?

　　(2)特殊疑问句双重问句：本结构属于特殊疑问句，谓语动词常是think，hope，believe，suppose，guess，say，consider，imagine等，宾语也由宾语从句充当，但没有引导词，前面主句的特殊疑问词在逻辑上是宾语从句的一部分。有些形容词如afraid，sure，glad，certain，surprised，pleased等也可用于本句型。如： ① Who do you think will be the likeliest candidate for the manager of human resource department? 你认为谁最可能是人力资源部经理? ② What do you think his explanation is? 你如何考虑他的解释? ③ It is necessary, do you think，to translate the whole article? 你认为整篇文章都翻译有必要吗? ④ Which mouse did you say you picked out? 你说你选哪种鼠标? ⑤ How long can you be sure they'll be here? 你能肯定他们在这儿呆多久?

　　【注意】本句型一般不用Yes或No回答，常把句型中的一般疑问句变成"陈述句+宾语从句" 来回答，陈述句也可后置，其前用逗号。如：-- How much do you think this car cost? -- I think it cost 4 000 dollars. -- 你认为这辆车得花多少钱? -- 我认为得花4000美元。

　　2) next此处用作副词，意为"下一步，然后"，也可作"其次；下次；次于...的"等。如： ① First you heat the fat; next, you add the onions. 首先你把油烧热，然后加洋葱。

　　② Tell me what to do next. 告诉我接着做什么。③ I'll tell you the answer when we meet next. 下次见面时，我将告诉你答案。④ I like tennis best of an and swimming next. 我最喜欢网球，其次是游泳。⑤ Tom is the next tallest boy in our class. 汤姆是我们班上身高第二的学生。

　　【拓展】next作形容词，意为"紧接着的；其次的；下一个的"可指时间、地点、顺序等；next也可作名词，意为"下一位／个"如：① Take the next left turn after the school. 到了学校见下个路口向左拐。 ② Call me up on Saturday next. 下星期六请给我打电话。 ③ They used to live next door to us. 他们以前住在我们隔壁。 ④ I shall tell you in my next. 我在下封信里告诉你。 ⑤ Mrs. James was the next to make a speech. 詹姆斯太太是下一位演讲人。
