解答 41．pollution 考查名词．根据句意：最大的一个问题是污染．用名词pollution．
42．makes/has made 考查动词时态．全文讲述的是一般事实，用一般现在时或现在完成 时．
43．louder 考查副词比较级．根据下文makes us become angry more easily，前文应是：噪音使我们说话得更大声．用副词比较级louder．
44．the 考查冠词．形容词最高级前用定冠词the．
45．to/for 考查介词．根据句意：在世界上它对生物是有害的．用介词to/for．
46．Firstly  考查副词．根据下文的Secondly，此处应是：Firstly．
47．is thrown 考查动词语态． it与throw之间是动宾关系，用被动语态，全文讲述的是一般事实，用一般现在时的被动语态． 
48．on 考查介词．"在地面上"用介词on．
49．or 考查连词．by bus和with our friends in the same car之间是选择关系，用连词or．
