Answer 1

【答案】is；recycled；natural；on；a；how；preventing；it；having；attached
【解析】本文主要讲述了人们对未来城市生活情况的猜测。

（1）is;考查be动词。根据making predictions is a risky business做预测是一项冒险的事情，句子中缺乏谓语动词，故为be。

（2）recycled；本句的含义为我们将使用许多循环的材料，本题表示过去，故本句空格处填循环的过去式recycled。

（3）natural；考查形容词。根据后文的名词and we will waste fewer natural resources我们浪费的自然资源会越来于少。

（4）on；本句的含义为我们将更多的依靠非传统的能源，rely on表示依靠的含义，故本句空格处填on。

（5）a；考查定冠词。由于后面所接名词为university，故用a。

（6）how；根据句意，一位老师问他的学生他们在2025年会如何管理拥有50000人口的城市。可见句中不缺乏成分，故为how.

（7）preventing；考查非谓语动词。由于前文中有谓语动词，且prevent environmental problems 阻止环境问题为主动形式。

（8）it；考查固定搭配，it is possible to do sth.做某事是有可能的。

（9）having；考查with短语的复合结构。根据句意：每个城市有它自己的远程诊所。可知为主动形式。

（10）attached；考查过去分词。根据句意，人们头上戴着高科技相机，便可以去世界任何地方，可知camera与attach是被动关系，故用过去分词。
