umm... Today, because of improvements in agricultural technology, the same amount of acreage produces twice as many apples as it did in 1910. (OG10#168)
umm...我是想用example來指出X number of Y/X amount of Y之類的東東在主語的位置時, Y才是動詞的真正的executor... twice as many trucks我*覺得*是可以, 可是as many指的對象很遠, 不太名顯... 舊的OG上好像有這一題...忘了
alienx举的例子怎么才能说明X number of Y在做主语的时候executor是Y而不是X呢?amount和acreage都是单数名词,我觉得这个例子不好。 另外还是不明白 that number 比the number好在哪里? 其实the也是有指代作用的呀,记得小学老师说,用the就是讲话双方都没有歧义的知道the A 的那个A是啥。在这句话里,我们都知道要是说number,肯定只有那个46900一个number可以说啊,大家都知道说的是那个number呀~(这么想不知道对不对)
2) C,twice the number of trucks的核心是 the number,所以the number作主语含义错,因为the number是无法came off the assembly lines的;
3) A也同C错误,不是数字从生产线上生产出来,应该是两倍数量的trucks came off the assembly lines
4) B正确。因为twice that number,就是因为 that的出现,使得that number指代46900这个数字 ,twice that number of作定语修饰trucks,因此but后面的句子的主语twice that number of trucks,和前面的句子主语 a total of 469,000 cars and trucks形成对比关系。从逻辑及含义上正确。
In 1914 a total of 469,000 cars and trucks were produced in the United States, but in 1929 almost twice that number of tucks alone came off the assembly lines. = In 1914 a total of 469,000 cars and trucks were produced in the United States, but in 1929 almost 938000 tucks alone came off the assembly lines.
