20、choosefrom意思是“从中挑选”。eg我有很多双鞋子可以选择，但我决定不了选哪双。Ihavemanypairsofshoes_,butIdontknowwhichpair_.2Thejourneymighttakeonlyaveryshorttimeinspaceshuttlesthattravelathalfthespeedoflight.用以光速一半速度飞行的太空穿梭机进行的旅程可能只要花很短的时间。分析：此句是that连接的定语从句。that引导的定语从句修饰先行词spaceshuttles,从句中的动词的人称和数由先行词spaceshuttles决定。3comparedwithl

21、ifeonEarth,lifeonmarswillbebetterinmanyways.与在地球上的生活相比,火星上的生活在很多方面将会更好.comparewith意思是“与做比较”。在句中是过去分词短语作状语,此时with和to可通用。eg与我们的那条路相比,这条路繁忙得多。Thisroadisquitebusy_ours.4Everystudentwillhaveacomputerathomeconnectedtointer-planetarynetwork.每个学生在家里有一台连接星际网络的电脑。connectto意思是“与连接”。这里的connectedto是过去分词后置作定语,修饰c

22、omputer。当然我们也可以用connectto结构表示“把和连接起来”。eg江阴大桥把江阴和靖江连接了起来.jiangyinBridge_jiangyin_jingjiang.T:well,boysandgirls,youreallydidagoodjobtoday.T：小结今天我们学习了一些描述火星生活的词汇、句型，并且讨论了火星上未来生活的优缺点。希望同学课后认真巩固课文内容，用自己的语言来简单描述火星生活。T:Todayshomework:Readthepassagealoud.2Finishofftheadditionalexercises.T:Thatstheendofmycla
