急!! 明天考试, 请NN们帮忙解释两题SC

1。The 151 member governments of the world bank are expected to increase the bank's funding by $75 billion, though some United States legislators cite an obstacle to congressional passage being the concern that the bank's loans will help foreign producers compete with American businesses.

Answer: as an obstacle to congressional passage the concern

Question:  为什么 "the concern, an obstacle to congressional passage,"  是错的呢?

2. With surface tempratures estimated at minus 230 degrees Fahrenheight, Jupiter's moon Europa has long been considered far too cold to support life, and with 60 square miles of water thought to be forzen from top to bottom.

Answer: Europa has long been considered far too cold ot support life, its

我也知道A不对, 可我觉得正确答案中也却个连接词, ex. ...with its.... 不然的话"its..." 这段话不久像是吊在那儿了吗?

3. The new image of Stone Age people as systematic hunters of large animals, rather than merely scavenging for meat, have emerged from the examination of tools found in Germany, including three wooden spears that archaeologists believe to be about 400, 000 years old.

Answer: mere scavengers of meat, has emerged from the examination of tools found in Germany, including...

 问: 可以用which include代替吗? 良种modifying的方法有区分吗?

完了完了...令考了这还搞不懂...请那为好心的高人指点指点啊。。。阿米驼佛了真是。。。

祝你明天考试顺利。以下个人意见给你参考一下：

1。如果选择"the concern, an obstacle to congressional passage,"  那么后面的定语从句that the bank's loans will help foreign producers compete with American businesses就变成修饰congressional passage了

2。如果加with,那么with its...就是修饰life了

3。应该可以的，因为在这里Germany是单数，所以不会引起歧义

to 楼上:

能否稍微解释一下WITH短语作伴随的用法呢?

to 楼上:

我刚刚查找了一下关于with短语作伴随的帖子,觉得主句后的with短语只能作伴随状语修饰前面的动词,你觉得呢?
