30、故选B。9.A none of sb./sth. 意为“没有一个，毫无”，其后动词一般用单数。故选A。10.C 11.B 根据此句“我下周会很忙” 可知周一周二都不行，所以选neither都不12.A形容词修饰不定代词放其后，此句又为肯定句，所以选A 13.B land为不可数名词，故选B14.A 回答how many强调数量，需用none回答三、阅读理解 （6选5）1.C 前文讲述杰克托德对净水感兴趣，由选项C中is also interested in“也对感兴趣”可知选C。2.E 短文第二段讲述这种机器的工作原理，选项E“这种机器能够用于净化污水”正是这一段的主题句。故选E。3.F 由后面的the plants make it cleaner可知，在阳光的作用下，动植物去掉水中的化学物质。故选F。4.D 后文介绍被处理过的水的作用，由转折连词but可知，选项D“它不能用来饮用和做饭”符合。故选D。5.A 后文“它能帮助减少使用干净水，也能够保护水资源不被污染”可知，前提条件是人们使用这种处理污水的机器。故选A。7原创精品资源学科网独家享有版权，侵权必究！学科网（北京）股份有限公司
