【解析】

文章大意：這篇短文主要給我們講述的是在未來，人們也許會去火星上居住，因為地球上的人口越來越多，而污染也越來越嚴(yán)重。去火星居住有很多優(yōu)點，如人們的居住空間會更大，人們都用機器人工作等。當(dāng)然，在火星居住也有它的缺點。如火星上的引力很小，食物不會像地球上那么好吃等。

【1】句意：我們自己的星球，地球正變得越來越擁擠和污染。

考查形容詞的辨析。Crowded擁擠的；modern現(xiàn)代的；developed發(fā)展的；serious嚴(yán)肅的。根據(jù)空后and polluted可知，此空應(yīng)填形容詞，結(jié)合句意可知，此空是“擁擠的”意思，應(yīng)填crowded，故選A。

【2】句意：目前，我們的宇宙飛船速度太慢，無法將大量人員運送到火星——這需要幾個月的時間。

考查介詞短語的辨析。At times有時；At last最后；By the way順便說；At present目前。根據(jù)However, by 2100, Spaceships can travel at half the speed of light. It might take us two or three days to get to Mars可知，此空是“目前”的意思，應(yīng)填At present，故選D。

【3】句意：這些植物將生產(chǎn)我們需要的食物和空氣。

考查動詞辨析。destroy摧毀；produce生產(chǎn)；grow生長；support支持。根據(jù)空前助動詞will可知，此空應(yīng)填動詞原形，結(jié)合句意可知，此空是“生產(chǎn)”的意思，應(yīng)填produce，故選B。

【4】句意：我們在火星上生活還有另一個問題。

考查名詞的辨析。hope希望；chance機會；problem 問題；mistake錯誤。根據(jù)空前another 可知，此空應(yīng)填名詞，結(jié)合This will be dangerous because we could easily jump too high and fly slowly away into space可知，此空是“問題”的意思，應(yīng)填problem，故選C。

【5】句意：為了防止這種情況，火星上的人類必須穿上特制的鞋子，使自己更輕。

考查動詞的辨析。refuse拒絕；prevent防止，阻止；realize意識；repair 修理。根據(jù)空前動詞不定式符號To可知，此空應(yīng)填動詞原形，結(jié)合This will be dangerous because we could easily jump too high and fly slowly away into space可知，此空是“防止”的意思，應(yīng)填prevent，故選B。

【6】句意：住在有10間臥室的大房子里是很有可能的，許多人相信機器人將完成我們大部分的工作。

考查形容詞辨析。changeable可變的；responsible負(fù)責(zé)的；possible可能的；impossible不可能的。根據(jù)空前is highly 可知，此空應(yīng)填形容詞作表語，結(jié)合句意可知，表示“人類住在10間臥室那么大的房子是可能的”，此空是“可能的”意思，應(yīng)填possible，故選C。

完形填空，它集閱讀理解、語法、詞法、句法于一體，是難度最大的題，重點考查語言綜合運用的能力。解題的方法第一要帶著空，通讀文章，搞清事件發(fā)生的背景。緊緊抓住上下文語境所提供的信息,充分利用各種線索，語法知識,以及句子之間的關(guān)系，詞的搭配，結(jié)合上下文背景語境，結(jié)合句意選擇適合語境的選項。做完型填空時，首先要通讀課文，明白主旨大意，然后再做題。例如，第1小題，句意：我們自己的星球，地球正變得越來越擁擠和污染�？疾樾稳菰~的辨析。Crowded擁擠的；modern現(xiàn)代的；developed發(fā)展的；serious嚴(yán)肅的。根據(jù)空后and polluted可知，此空應(yīng)填形容詞，結(jié)合句意可知，此空是“擁擠的”意思，應(yīng)填crowded，故選A。
