250.(25489-!-item-!-188;#058&001585)(GWD30-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



答案是C。默。。我真的越来越不明白more than 结构了。

个人想选择B。我觉得C少了一个is。

如果按照C的结构，比较的应该是heart attack patients和balloon procedure by itself

如果按照B（或者其他有is）的结构，比较的才是两种不同的balloon吧？

或者难道我理解错了要比较的东西？

p.s.我到哪里能找到详细的关于more than的用法呢- -~谢谢大家



256.(28362-!-item-!-188;#058&003003)(T-4-Q1 TS-7-41)



Scientists have dated sharp-edged flakes of stone found in the fine-grained sediments of a dry riverbed in the Afar region of Ethiopia to between 2.52 and 2.60 million years ago, pushing back by more than 150,000 years the earliest date when it is known that humans made stone tools.

A. when it is known that humans made

B. at which it is known that humans had made

C. at which humans are known to have made

D. that humans are known to be making

E. of humans who were known to make



答案是C。不明白为什么是用完成时态。

问的太多了啊 一下写不完
242：more than 在这里比较的是状语部分，及：According to public health officials, in 1998 Massachusetts became the first state in which more babies were born to women over the age of thirty than （babies were born to women ）under it.
前后结构一致 故只留下状语部分

256题 其实用排除法可以快点，d e毙掉，a b it指代不清。在考场上的话应该是这样做吧。
时候分析的话，可以这么说么？假设公元前1000年被认为人们开始懂得制作石器，那么这个动作一直持续到现在 那么应该使用完成时态吧。

谢谢楼上啊~~那能不能问下250题呢~~万分感谢~~~

250你想多了。。 better A than B。。要平行，所以A是短语，B不可能是句子  BE选项排除
A 没有that 排除       C用whether表是否的意思，且时态正确
D 时态错了 determine that A with 看着就不对。。

fay009

不对啊。。
balloon angioplasty preceded by ultrasound is any better for heart attack patients than the balloon procedure by itself

。。。

不是X is better for B than C么？

那不就是X对于B比对于C好的意思么？

应该改成X is better for B than C is才对吧？

selinalover

去掉for doing 和不含that的结构之后，只有cd两个选项了，d：more research was needed to determine that....更多的实验要做 为了确定一个事实。不合理啊

fay009

一定要排除没有that的结构么
