初三英语Unit 4 Topic 3 Perhaps people will fly to Mars. 湘教版【本讲教育信息】一. 教学内容： Unit 4 Topic 3 Perhaps people will fly to Mars. 也许人们将飞向火星。二. 重点、难点：（一）1. We will be able to do anything that can be done on the earth.我们将能做在地球上能做的任何事情。that can be done on the earth 定语从句修饰 anything。从句的谓语用的是带有情态动词的被动语态，构成的形式为“情态动词+be +及物动词的过去分词”Well raise money for the children who live in the poor areas. （定语从句修饰孩子children）我们将为那些生活在贫困地方的孩子筹集资金。Do you know the boy who is swimming in the river？（定语从句修饰the boy）你认识那个正在河里游泳的男孩吗？These trees must be planted tomorrow.这些树必须在明天栽种。More satellites must be sent into space.更多的人造卫星必须发射进入太空。 2. He thinks they are reading on the Internet in order to learn about humans culture.他认为他们正在互联网上阅读，以便学习人类的文化。in order to 为了，表示目的，后接动词不定式相当于so as to。in order to 既可放在句首又可放在句中，so as to 只能放在句中，不可放在句首。它们的否定形式都是在to前加not，即in order not to ，so as not to ，它们后只能接动词原形，如果后面接目的状语从句可用in order that 或so that。如：They did anything in order to / so as to make money.为了赚钱他们什么事都肯做。In order not to fail the exam, he studied for more than ten hours every day.为了考试不失败，他每天学习了十多个小时。She went to England last year in order that / so that she could learn standard English.她去年去了英国，为的是学习标准英语。3. But I dont believe anything in the movie. I dont think aliens can be found in space.但我不相信在电影里看到任何东西，我认为在太空中找不到他们。当think（认为） believe（相信） suppose（猜想） imagine（想像） expect（期望）等动词后接宾语从句为含有not 的否定句时，该否定应移至主句，即否定主句的谓语动词，为否定转移。如：我认为明天不会下雨。I dont think it will rain tomorrow. （）I think it wont rain tomorrow. （×）我相信他不会回来。I dont believe he will come back. （）I believe he wont come back. （×）但注意主句的主语是第二、三人称，否定式一般不转移。如：He supposes they wont win the game. 他猜想他们赢不了比赛。（二）1.
