The fact that so many people still smoke in public places________that we may need a nationwide campaign to raise awareness of the risks of smoking. A. suggest B. suggests C. suggested D. suggesting答案： 1. D 句意：这家工厂用了65%的原材料，剩余的被作为它用。raw materials是先行词，which引导的定语从句中，the rest作主语；the rest作主语时，谓语的数由其后的名词而定，而which＝raw materials，所以谓语要用复数形式；由主句中的时态可知，从句中要用一般过去时态。故选D项。 2. A “国家三分之一的领土”在概念上是单数，故系动词用单数；而“国家公民的大多数”是复数，故系动词用复数。句意：这个国家三分之一的领土被树木覆盖且多数公民为黑人。故选A项。 3. B 考查动词的时态和主谓一致。句意：目前许多人仍然在公共场所吸烟的这一事实表明我们需要开展一场全国范围的运动来提高人们对吸烟的危险性的认识。根据句意可知应使用一般现在时；本句的主语是The fact，故谓语动词应用第三人称单数，故选B项。名校模拟演练 |
