Helr-SC-001 Although the investigation that people who were taking the statins were more likely to report lower overall energy and more fatigue with exertion than those who had been randomized to the placebo will need to be replicated in larger trials, doctors and patients should be reminded that weighing the pros and cons of starting on statins is important. B. will need to be replicated in larger trials, it should remind doctors and patients that it is important to weigh the pros and cons of starting on statins.
这里的B选项是正确选项,其中就出现了it的不同“指代”。 这是B选项的解析: B. 正确。“It”很明确的指代“investigation”,并且后半句用主动语态很明确的指出了前后两个半句的关系,让“investigation”和“doctors and patients”的关系变的很明确。 后半句中的两个“it”没有问题,一个指代“investigation”,另一个是“to weight……”(形式主语)。
我觉得it不可以在做形式主语的同时又指代名词 把it作为形式主语有两种situation,一种是推迟infintive subject,另一种是推迟that-clasue subject, 所以指代的也是他们,不是名词。“Do not look for a noun antecendent for a placeholder'it' ."
