Even though the direct costs of malpractice disputes amounts to a sum lower 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.
A) amounts to a sum lower
B) amounts to less
C) amounted to less
D) amounted to lower
E) amounted to a lower sum
正确答案是C,我的疑问是:记忆中好象costs是不可数名词啊,怎么OG里面提到了costs是复数名词需要和谓语相一致呢?另外,less这个词我记忆中是修饰不可数名词的。如果我大脑里不储存这些记忆,会对OG的解释非常赞同,但是大脑的记忆让我对OG的解释有怀疑,感谢大家帮助自由解决这个记忆疑惑问题 |
