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.

题目分析：
略。
选项分析：
A选项：过去分词短语preceded with ultrasound应改为preceded by ultrasound。这是因为，过去分词表被动，而被动语态规定，be done by A中的A才是do在逻辑上的主语。由于超声波是在逻辑上发出precede这个动作的主语，所以应该用介词by。
B选项：介词短语for determining应改为不定式短语to determine，这点考查了不定式和ing的区别，用之于本题，for determining是need的宾语补足语，因此应有need的约束力决定。显然地，need的约束力较强，应该用不定式短语做宾语的补足语。
C选项：Correct. 本选项在语法和逻辑上均是正确的。
D选项：preceded with错误同选项(A)；determine的内容发生在主句agree之后，所以应该用agree向后推移的时态：一般现在时is，而不能用一般过去时was。
E选项：介词短语for determining应改为不定式短语to determine错误同选项(B)。
1，也就是说是否需要加that,在这个题目看来，既不是考点，也不具有逻辑意思上的错误。
2，总感觉balloon angioplasty 后面跟的preceded是错误的，因为未划线部分是balloon procedure，所以认为应该是balloon angioplasty proceeded,进行，进展的意思，这个时候用by似乎就可以了。而preceded的意思是先于....之前......用by的话，逻辑意思上不搭调啊.
1. 完全正确。千万不能马后炮的认为这个that需要添加。因为，在考题中，省略这个that，和不省略这个that都很常见，绝对不是错误。
2. 这是个很好的问题。其实不是写错了，是没划线部分省略了这个preceded。原句应该是：
whether balloon angioplasty preceded by ultrasound is any better for heart attack patients than the balloon procedure preceded by itself
itself的指代是？感谢老师
balloon procedure呀～意思用超声波的气囊血管成形术和普通的气囊血管成形术的比较。
我再多读几遍>.
