OG11TH-3原题题干如下: Diabetes, together with its serious complications, ranks as the nation's third leading cause of death, surpassed only by heart disease and cancer. 我的疑问是:如果没有第一个和第二个逗号,谓语动词rank应该用单数形式还是复数形式? OG11TH-4题目如下: A survey by the National Council of Churches showed that in 1986 there were 20,736 female ministers, almost 9 percent of the nation's clergy, twice as much as 1997. 其中D选项是这样的:(D) double the figure for 1997 我的问题是:(D)选项这里的“for”如果换成“of”或者“in” 还会是正确的吗? OG11TH-- 8题目如下 Rising inventories, when unaccompanied correspondingly by increases in sales, can lead to production curbacks that would hamper economic growth. 这道题的解释中提到:when indicates a period of time; if indicates a condition. if is preferable here. 其中(B)选项是:when not accompanied by corresponding increases in sales, possibly leads 这个选项的解释中有一句是说:when is used to refer to a condition. 我的疑问是:B 选项中关于when的解释,是说这个词应该这么用;还是说这个when在这句话中是这样用的,而这样使用是不对的。 谢谢高手指点迷津! |
