62．D　推理判断题。根据题干中的关键词“last paragraph”定位到该段第一句“You can take steps to save water in your home.”，且它后面的内容都是围绕这个主题句展开的。

　　63．D　主旨大意题。根据题干中的关键词“mainly about”定位到全文的内容。文章第一段讲的是“铺设马路、停车场会导致地下水减少”，后三段讲述了“为了满足我们的用水需求，我们能做些什么”。所有这些讲的都是人类活动对地球水资源供给的影响，故选D。

　　C7 [2017·安徽卷] ----D

　　“People are ruder today because they are rushed and more ‘time poor’ than ever before，” says Patsy Rowe, “Manners_have_fallen_off_the_radar(雷达)．” Due to our strong attraction to electronic equipment it is a wonder more people don't wake up each morning and greet the singing birds with a complaint(抱怨)about the noise. Here are some examples of rudeness.

　　Some people prefer to do almost everything over the Internet. To them, dealing with an actual human is like an evolutionary step backward. It feels very slow because humans don't work at 4G speeds. When you have dinner with friends, you will often notice someone paying more attention to his mobile phone. We have programmed ourselves to think that every new message brings life－changing news, so taking calls and checking our texts are more important than talking to the people we are with. What is worse, some people even tend to send anonymous(匿名的) rude messages by email.
