标题: GWD-30-Q29

Researchers agreed that the study of new treatments for heart attack patients was extremely important but more research was needed to determine that balloon angioplasty preceded with ultrasound was or was not any better for heart attack patients than the balloon procedure by itself.

A

more research was needed to determine that balloon angioplasty preceded with ultrasound was or was not any better for heart attack patients than

B

more research was needed for determining whether or not balloon angioplasty preceded by ultrasound is any better for heart attack patients than is

C

that more research was needed to determine whether balloon angioplasty preceded by ultrasound is any better for heart attack patients than

D

that more research was needed to determine that balloon angioplasty preceded with ultrasound was any better for heart attack patients than

E

that more research was needed for determining that balloon angioplasty preceded by ultrasound is or is not any better for heart attack patients than is

此题两个答案一个是C,一个是B,B个人觉得牵涉到whether冗余,C似乎那个any直接写又不太好.

很困惑,另有一个问题就是这里为什么都用IS,而不是与主句的was保持一致呢?

大家帮忙看看这题啊, why "is"?not"was"

时态一不一致不是解题的关键

重点是平行,仔细看未划线部份使用by itself与C的by ultrasound平行

考试时肯定是这样选,但问题是这里为什么用is ,是否有其他语法点在里面
