　　1. What are the biggest problems facing the earth? 地球面臨著的最大問題是什么? (p. 65 Warming Up Ex.1)

　　1) 現在分詞短語facing the earth在句中作定語，相當于定語從句that face the earth. face此處用作及物動詞，意為"面向，朝"，作此義也可用作不及物動詞，常和介詞to，toward或on連用。如： ① She turned to face the newcomer and introduced herself. 她轉過身來面對新來者作了自我介紹。 ② The building faces the park. 那座建筑物面對著公園。③ The window faces on the street.窗戶面對著銜道。 ④ -- How does this house face? --It faces to the east. -- 這座房屋面朝哪邊? -- 朝向東邊。

　　【拓展】 face還可意為"面對／臨(問題或不愉快的情況)"。如：① Manufacturing industry faces a grim future if the government pursues its present policies. 如果政府繼續(xù)推行現行政策，制造工業(yè)就會面臨嚴酷的未來。② He couldn't face his boss after marking such a fool of himself at the meeting. 他在會上做出了這樣的丑事之后，不敢面對自己的老板。

　　【注意】face the music不能譯為"面對音樂"，其意思是"面對失敗，接受批評，承擔后果"。如：He knew he'd never get away with it so he decided to face the music and give himself to the police. 他知道自己已經無法逃脫，所以他決定承擔后果并向警察自首。

　　2. Why is she giving this speech? 她為什么發(fā)表演講呢? (p. 66 Listening Part 1 No.1)

　　speech此處意為"演說，演講"，常用作單數形式，"發(fā)表演說"多用動詞give，make，deliver等與之搭配。如：① I had to give a speech to the Press Club. 我不得不向記者俱樂部發(fā)表演說。② He delivered a speech in English on world-peace. 他用英語發(fā)表了一篇關于世界和平的演說。

　　【辨析】speech，lecture；talk

　　3. What do you think she will say next? 你認為她下步講什么呢? (p. 66 Listening Part 1 No.4)

　　1) 本句為雙重問句。雙重問句有兩種形式：

　　(1)一般疑問句型雙重問句：本結構屬于一般疑問句，主句謂語動詞常是ask (詢問)，tell (告訴)，know (知道)，realize (意識到)，make sure (確信)等，賓語由特殊疑問詞引導的賓語從句充當。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)特殊疑問句雙重問句：本結構屬于特殊疑問句，謂語動詞常是think，hope，believe，suppose，guess，say，consider，imagine等，賓語也由賓語從句充當，但沒有引導詞，前面主句的特殊疑問詞在邏輯上是賓語從句的一部分。有些形容詞如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? 你認為誰最可能是人力資源部經理? ② What do you think his explanation is? 你如何考慮他的解釋? ③ It is necessary, do you think，to translate the whole article? 你認為整篇文章都翻譯有必要嗎? ④ Which mouse did you say you picked out? 你說你選哪種鼠標? ⑤ How long can you be sure they'll be here? 你能肯定他們在這兒呆多久?

　　【注意】本句型一般不用Yes或No回答，常把句型中的一般疑問句變成"陳述句+賓語從句" 來回答，陳述句也可后置，其前用逗號。如：-- How much do you think this car cost? -- I think it cost 4 000 dollars. -- 你認為這輛車得花多少錢? -- 我認為得花4000美元。

　　2) next此處用作副詞，意為"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. 首先你把油燒熱，然后加洋蔥。

　�、� Tell me what to do next. 告訴我接著做什么。③ I'll tell you the answer when we meet next. 下次見面時，我將告訴你答案。④ I like tennis best of an and swimming next. 我最喜歡網球，其次是游泳。⑤ Tom is the next tallest boy in our class. 湯姆是我們班上身高第二的學生。

　　【拓展】next作形容詞，意為"緊接著的；其次的；下一個的"可指時間、地點、順序等；next也可作名詞，意為"下一位／個"如：① Take the next left turn after the school. 到了學校見下個路口向左拐。 ② Call me up on Saturday next. 下星期六請給我打電話。 ③ They used to live next door to us. 他們以前住在我們隔壁。 ④ I shall tell you in my next. 我在下封信里告訴你。 ⑤ Mrs. James was the next to make a speech. 詹姆斯太太是下一位演講人。
