【解析】

1句意:和地球上的生命相比較,火星上的生命在某方面會更好。此處表示被比較,故用過去分詞作狀語,故為Compared。

2句意:一種非常流行的娛樂形式是在線游戲。有不定冠詞a修飾,故用單數(shù)名詞,故為entertainment。

3句意:科學(xué)家同意人類在火星上生活在未來將是可能的嗎?作為介詞in的賓語,故用agree的名詞,故為agreement。

4句意:目前,我們的飛船太慢了而無法承載大量的乘客去火星。too+形容詞/副詞+to do sth“太……而不能做某事”,故第一空用to carry。第二空有large numbers of修飾,故用復(fù)數(shù)名詞,故為passengers。故此處為(1). to carry (2). passengers。

5句意:“親愛的外星人,人類正在考慮搬到另一個星球……”,根據(jù)謂語are是復(fù)數(shù),故主語用復(fù)數(shù)名詞,故為humans。

6句意:有可能我明天下午見到你嗎?有形容詞any修飾,用名詞,根據(jù)謂語is是單數(shù),故謂語用單數(shù)名詞,故為possibility。

7句意:食物將最有可能以藥片的形式,將不會如此的美味。修飾be動詞,故用副詞,故第一空為probably。第二空作為be動詞的表語,有副詞so修飾,故用形容詞,故為tasty。故此處為(1). probably (2). tasty。

8句意:來自地球食物很難找到。主語goods是復(fù)數(shù),故謂語用復(fù)數(shù),故為are/will be。

9句意然而,宇宙飛船將會飛得如此之快,以至于火星之旅可能會非常不舒適。根據(jù)the spacecraft would travel so fast 可知宇宙飛船飛得非常快,因為火星之旅不舒服,作為be動詞的表語,有副詞quite修飾,故用形容詞,故為uncomfortable。

10句意:據(jù)希望人們可以一切重新開始,在火星上建立一個更好的世界。根據(jù)句意It is hoped that…“據(jù)希望……”,故為is hoped。

11句意:火星大約繞太陽兩年一次。根據(jù)句型It takes sb/sth some time to do sth“做某事花費某人/某物時間”,故為to circle。

12句意:火星上的生活既有挑戰(zhàn)性,也非常有趣。as well as連接并列成分,前面是形容詞interesting,故此處用形容詞,故為challenging。

13句意:火星美元是電子的,儲存在火星銀行里。結(jié)合句意,此處表示被動,故用過去分詞stored。

14句意:我們的星球,地球,由于人口的快速增長,正變得越來也擁擠,越來越污染。作為系動詞become的表語,故用形容詞,故為(1). crowded (2). polluted。

15句意:去火星旅行的人需要頭盔,空氣罐,干制食品,電力包和睡袋。第一空表示干制食品,故用過去分詞dried作定語,dried food干制食品。第二空表示用于睡覺的袋子,故用動名詞sleeping作定語修飾bags,sleeping bags睡袋。故為(1). dried (2). sleeping。

16句意:人們將不得不穿上專門為防止自己漂浮到太空的靴子。修飾動詞designed,用副詞,故第一空為specially。第二空根據(jù)短語prevent sb from doing sth“阻止某人做某事”,故第二空為floating。故為(1). specially (2). floating 。

17句意:幾天前在陽光鎮(zhèn)的學(xué)校里進行了這項調(diào)查。結(jié)合句意,主語the survey與謂語carry之間是被動關(guān)系,根據(jù)a couple of days ago可知此處用一般過去時,主語the survey是第三人稱單數(shù),故謂語用第三人稱單數(shù),故為was carried。

18句意:地球上的人口仍然在快速地增長。修飾動詞increasing,用副詞,故為rapidly。

19句意:住在火星上將是什么樣?此處it是形式主語,動詞不定式to live作為真正的主語,故為to live。

20development
