(GWD-12-Q14) 比较 In 1914 a total of469,000 cars and trucks were produced in the United States, but in 1929 almosttwice the numbers of trucks alone came off the assembly lines. A. the numbers oftrucks alone B. that number oftrucks alone C. the number of trucksby themselves D. as many trucksthemselves (B) E. as many trucks bythemselves
题目释义:In 1914 a total of469,000 cars and trucks were……,but in 1929 almosttwice that number of trucks…… 1914年cars和trucks共制造了469000辆,而在1929年仅trucks单独就有原来总数两倍那么多从组装线上下线。
考点:1. twice只能作副词, 在句子中表达的意思却是比较, 这样的题目, 首先要弄清楚比较的双方是否合理, 如果合理的话, 再看twice作为副词的位置: 可以用在as..as或比较级之前, 也可以放在比较点的名词之前, 担要保证twice前后的词要能直接搭配(副词的作用).eg: He is twicethe man he was. = He has twice the strength he had =He is twice as strong as hewas. 2. Number的用法:a number of(大量的),the number of(……的数量),numbers of (许多)。详见新prep1-209(笔记P43) 选项分析:A. the numbers错误,twice后面要跟单数的number,即twice the number;但是改为the number后,指代特定的数字还是用that number更为明确 B. Correct;came off作过去分词修饰trucks;that number指代前面总和的469000,如果是the number,没有指代对象,似乎说是the number of trucks C. the number指代不清;by themselves是指卡车出售时没有附带配件,即单车出售,与alone意思并不相同。 D. 用as many trucks时,整个句子的意思是“1914年汽车和卡车一共生产了469,000辆,而1929年两倍的卡车下了生产线”,句子前后并没有直接逻辑联系,前面句子并没有讲卡车有多少辆;trucks themselves这样的结构(X itself)中,themselves反身代词是对trucks的同位语,表示强调是trucks而已,我们往往可以看作没有反身代词,就如同同位语往往与句子主成份无关一样。 E. as many trucks错误同D;by themselves错误同C
