【解析】

短文大意：本文关注的是环境污染问题。文中指出，现在的生活比数百年前是更容易了，但它也带来了一些新的问题。最大的问题之一是空气污染。告知人们为了人类，为了后代，我们必须要保护我们的家园——地球。

【1】句意：地球是我们的家。名词home需用形容词性物主代词修饰；根据句意语境和英文提示，可知填our。

【2】句意：今天的生活比几百年前容易，但也带来了一些新问题。but表转折，连接两个并列句；本句缺谓语动词，根据上文Life today is easier than it was hundreds of years ago,，可知本句是说过去的动作对现在的影响，需用现在完成时；it是单数第三人称，故填has brought。

【3】句意：最大的问题之一是污染。本句是主系表结构，One of+可数名词的复数作主语，谓语动词用单数人称，系词需用is；根据句意语境和英文提示，可知填is。

【4】句意：现在人类正在慢慢地污染整个世界。pollute污染，动词需用副词修饰；根据句意语境和英文提示，可知填slowly。

【5】句意：它对世界上生物是有害的。living things生物；根据句意语境和英文提示，可知填living。

【6】句意：许多国家不允许人们在城市的房子和工厂里燃烧任何有害空气的东西。many许多的，后接复数名词；根据句意语境和英文提示，可知填countries。

【7】句意：人们都说最好骑自行车。it's best to do最好做某事，固定结构；根据句意语境和英文提示，可知填to ride。

【8】句意：但即使在发达国家，大多数人也不骑自行车上班。by bike骑自行车；根据句意结构和词性提示，可知填by。

【9】句意：所以越来越多的人把自行车收起来，开车上班，然后情况变得越来越糟。put away和go to work是先后发生的动作，并列关系，需用and连接；根据句意结构和词性提示，可知填and。

【10】句意：我们应该有专门的自行车专用道路，让司机把车开进城市变得如此困难和昂贵，以至于他们会回去使用自行车。and连接并列结构，根据and expensive和that they will go back to use their bikes.，可知把车开进城不容易，故填difficult。

短文填空，要求根据句意结构和所给单词提示填空，使句意通顺、文意连贯。主要考查单词形式，包括名词的单复数和所有格、动词的三单形式、非谓语动词、基数词或序数词，主格代词/宾格代词和物主代词（形容词性物主代词/名词性物主代词）等。这类题目难度不大，重点是掌握句意，在理解的基础上把握句子时态，从而判断所给单词的正确形式。
