网友回答
(答案→)第一行：their改为his ；
解析：
第一行：此处代指：man应该使用单数的：his，也可参考下文的：his way of life，故此their改为his；
第二行：此处是单句不需要连词，所以that去掉；前后句子属于转折关系，故此thus改为however；
第三行：句子主语为：changes是复数，所以应该把has改为have；名词air为不可数，the多余；单词increasing为元音读音开头，所以a改为an；
第四行：此处应该使用连词：as表示正如、正像，所以like改为as；此处bring about表示带来、造成之意；
第六行：分析结构可知：laws和动词pass属于被动关系，所以pass改为passed；句子译文如下：由于对生活坏境缺少关爱造成的严重后果，所以属于被动关系，故此causing改为caused。
