短文大意：本文關(guān)注的是環(huán)境污染問題。文中指出，現(xiàn)在的生活比數(shù)百年前是更容易了，但它也帶來了一些新的問題。最大的問題之一是空氣污染。告知人們?yōu)榱巳祟�，為了后代，我們必須要保護(hù)我們的家園——地球。

【1】句意：地球是我們的家。名詞home需用形容詞性物主代詞修飾；根據(jù)句意語境和英文提示，可知填our。

【2】句意：今天的生活比幾百年前容易，但也帶來了一些新問題。but表轉(zhuǎn)折，連接兩個(gè)并列句；本句缺謂語動(dòng)詞，根據(jù)上文Life today is easier than it was hundreds of years ago,，可知本句是說過去的動(dòng)作對(duì)現(xiàn)在的影響，需用現(xiàn)在完成時(shí)；it是單數(shù)第三人稱，故填has brought。

【3】句意：最大的問題之一是污染。本句是主系表結(jié)構(gòu)，One of+可數(shù)名詞的復(fù)數(shù)作主語，謂語動(dòng)詞用單數(shù)人稱，系詞需用is；根據(jù)句意語境和英文提示，可知填is。

【4】句意：現(xiàn)在人類正在慢慢地污染整個(gè)世界。pollute污染，動(dòng)詞需用副詞修飾；根據(jù)句意語境和英文提示，可知填slowly。

【5】句意：它對(duì)世界上生物是有害的。living things生物；根據(jù)句意語境和英文提示，可知填living。

【6】句意：許多國(guó)家不允許人們?cè)诔鞘械姆孔雍凸�廠里燃燒任何有害空氣的東西。many許多的，后接復(fù)數(shù)名詞；根據(jù)句意語境和英文提示，可知填countries。

【7】句意：人們都說最好騎自行車。it's best to do最好做某事，固定結(jié)構(gòu)；根據(jù)句意語境和英文提示，可知填to ride。

【8】句意：但即使在發(fā)達(dá)國(guó)家，大多數(shù)人也不騎自行車上班。by bike騎自行車；根據(jù)句意結(jié)構(gòu)和詞性提示，可知填by。

【9】句意：所以越來越多的人把自行車收起來，開車上班，然后情況變得越來越糟。put away和go to work是先后發(fā)生的動(dòng)作，并列關(guān)系，需用and連接；根據(jù)句意結(jié)構(gòu)和詞性提示，可知填and。

【10】句意：我們應(yīng)該有專門的自行車專用道路，讓司機(jī)把車開進(jìn)城市變得如此困難和昂貴，以至于他們會(huì)回去使用自行車。and連接并列結(jié)構(gòu)，根據(jù)and expensive和that they will go back to use their bikes.，可知把車開進(jìn)城不容易，故填difficult。

短文填空，要求根據(jù)句意結(jié)構(gòu)和所給單詞提示填空，使句意通順、文意連貫。主要考查單詞形式，包括名詞的單復(fù)數(shù)和所有格、動(dòng)詞的三單形式、非謂語動(dòng)詞、基數(shù)詞或序數(shù)詞，主格代詞/賓格代詞和物主代詞（形容詞性物主代詞/名詞性物主代詞）等。這類題目難度不大，重點(diǎn)是掌握句意，在理解的基礎(chǔ)上把握句子時(shí)態(tài)，從而判斷所給單詞的正確形式。
