importantsentences(ppt)
1therewillbevariousdesignsforsettlerstochoosefrom.将有许多种设计可供移居者选择。
tochoosefrom…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_____(tochoosefrom),
butidon’tknowwhichpair____.(tochoose)
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。
3comparedwithlifeonearth,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.(compared…with/to)
4everystudentwillhaveacomputerathomeconnectedtointer-planetarynetwork.每个学生在家里有一台连接星际
