3.Atpresent,ourspacecraft774.Withthedevelopmentoftechnology,bytheyear2100,thejourneymightonlytakeabout20minutesinspacecraftthattravelatthespeedoflight！随着科技的发展,到2100年,乘坐以光速飞行的宇宙飞船,行程或许只要大约20分钟！

5.Foodwouldmostprobablybe796.ThegravityonMarsisonlyaboutthree-eighthsofthatontheearth.

火星上的重力大约只有地球上的八分之三。在表示分数时,分子用基数词,分母用序数词。分子如果大于1,分母须用复数形式。分子、分母之间有无连字符均可。

e.g.1/32/5one-thirdtwofifths6.ThegravityonMarsisonly80在做比较时,我们常用that/those指代句中类者相同的那一部分。通常that用于指代可数名词数或者不可数名词,those用于指代可数名词复数。此句中的that指代前面的gravity。e.g.

火星上的空气要比起球上的稀薄很多。

TheaironMarsismuchthinnerthan_____ontheearth.that在做比较时,我们常用that/those指代句中类者相同的817.ComparedwithlifeonEarth,lifeonMarswouldbebetterinsomeways.
