高三英语课文理解 Unit 17 Grade 1

　　1. How long will it take you to complete the trip? 你旅行全程需要多长时间？

　　表达某人做某事需要多长时间常用It takes sb + time + to do sth. 句型。句中的不定式是真正主语，it 是形式主语。对time提问用how long：

　　It will take me two weeks to complete the job. 我需要两星期才能完成这项工作。

　　How long did it take you to learn English so well? 你花了几年多长时间把英语学得这么好？

　　2. It is hoped that形式主语结构，真正的主语是that引导的名词从句。It is hoped that they will pass the exam tomorrow. 希望他们能通过明天的考试。 It is hoped that more and more people will eat healthy food. 希望越来越多的人饮食健康。

　　类似的结构有许多: It is said that(=Somebody says that)据说 It is believed that (People believe that)据信 It is supposed that(People suppose that...)据认为... It is reported that...(Somebody reports that...)据报道...

　　3. We are trying to collect money for a wildlife project. 我们正在设法募集资金搞一个野生动物项目。

　　collect money 筹集资金：They decided to hold concerts to collect money for the Hope Project. 他们决定举办音乐会为希望工程筹集资金。还可以用raise money：他们靠演出筹集资金:They raised money by performance.
