In the 1980's the rate of increase of the minority population of the US was nearly twice as fast as the 1970's. A. twice as fast as B. twice as fast as it was in C twice what it was in 答案是C 但是B哪里错了? 有一句结构差不多的话是被作为例句的:the economy of Florida is more diversified than it was ten years ago. 两句的区别就在于一个是用as adj. as一个是用more adj. than的结构。 是不是as adj. as 是不可以用B这种结构的?而more adj. than就可以? 我的理解是B的是A in 1980's is twice as fast as (it was) in 1970's. 应该没有问题的吧~~? 如果这句话改成In the 1980's the rate of increase of the minority population of the US was faster than it was in the 1970's.在语法上对不对的呢? 第二个问题,前面出现过的那个词应该用that 或者those代替的吧..不能用it,对么? |
