OG 90, The results of the company's cost-cutting measures are evident in tis profits, which increased 5 percent during the first 3 months of this year after it fell over the last two years. OG 上解释说profits fall是在increase 之前,所以应该在动词形式上体现先后。
正确选项:which have inceased 5 percent during the first 3 months of this year after falling.
在这儿after falling 表示的时态是什么,求解答。
