数词 1．The factory used 65 percent of the raw materials，the rest of which ______ saved for other purposes. A．is B．are C．was D．were 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。．Onethird of the country ______covered with trees and the majority of the citizens ______ black people. A．is；are B．is；is C．are；are D．are；is 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。．The girl found the Tshirt sold online was______that in the supermarket. A．as half cheap as B．cheap as half as C．the half price of D．half the price of D 句意：这个女孩发现网上卖的T恤衫是超市里卖的价格的一半。倍数的表达有三种方式：1）倍数＋as＋adj./adv.＋as＋被比对象，这一句型中，如果形容词修饰一单数可数名词，那么要把形容词提到冠词的前面来，即：倍数＋as＋adj.＋a/an＋单数可数名词＋as＋被比对象；2）倍数＋形容词或者副词的比较级＋than＋被比对象；3）倍数＋the＋size/width/depth/length/height＋of＋被比对象。这里考查的是第三种形式。．______ of the land in that district ______ covered with trees and grass. |
