答案： amounted to less。 即原句正确为： Even though the direct costs of malpractice disputes amounted to less than one percent of the $541 billion the nation spent on health care last year, doctors say fear of lawsuits plays a major role in health-care inflation.
书上解释说，last year 决定状语从句必须使用一般过去时。 我看了答案后也比较能理解价格需同一时间段比较 所以amount to要用一般过去式。 但是，我一开始做这道题的时候把the nation spent on health care last year看做修饰 the $541 billion ，所以选了amounts to less。请问这种理解错在哪。。。。。。作者: wyw1018 时间: 2012-9-5 14:07
修饰没错，amount to 的主语是costs是复数，不能用amounts。
