26/35Difficultsentences27/35Thejourneymighttakeonlyabout20minutesinspacecraftthattravelathalfthespeedoflight.用以光速二分之一速度飛行太空穿梭機進行旅程可能只要花約20分鐘時間。

分析：此句是that連接定語從句。that引導定語從句修飾先行詞spacecraft,從句中動詞人稱和數(shù)由先行詞spacecraft決定。28/35ComparedwithlifeonEarth,lifeonMarswillbebetterinmanyways.與在地球上生活相比,火星上生活在很多方面將會更加好.

comparewith…意思是“與……做比較”。在句中是過去分詞短語作狀語,此時with和to可通用。

29/35

Everystudentwouldhaveacomputerathomeconnectedtoaninter-planetarynetwork.每個學生在家里有一臺連接星際網(wǎng)絡電腦。

connectto意思是“與……連接”。這里connectedto是過去分詞后置作定語,修飾computer。當然我們也能夠用connect…to…結(jié)構(gòu)表示“把……和……連接起來”。30/35Exercises31/35Task1--WordsPage54,FinishB132/35Exercises:1.It___________(hope)thatwewouldhaveabetterworldonMars.2.The____________(人口）ofChinain21007wouldbelarger.3.Thiskindofshoesistoo________________(comfortable)formetowear.4.Theearthisa_________.(行星）5.________(人類）canmakerobotsdosomework.6.Thisareaisbadlyp_______.Somethingmustbedonetoprotecttheenvironment.7.Withpoutgravity,wewill______(漂?。﹊nthespace.ishopedpopulationuncomfortableplanetHumansollutedfloat33/35當前；現(xiàn)在變得越來越擁擠
