OG11th-62,90; verbal91

第一次在这里发贴，大家帮帮忙啊！：）

第一道：是属另外一本verbal中的第91道语法题：

In theory, international civil servants at the United Nations are prohibited from continuing to draw salaries from their own governments; in practice, however, some governments merely substitute living allowances for their employees’ paychecks, assigned by them to the United Nations

B for the paychecks of their employees who have been assigned

C for the paychecks of their employees, having been assigned

我不知道两个应该选哪一个，我觉得两个都没有错62，答案选B，大家帮帮忙，我好象对who/ ing的用法还不是很清楚啊？

第二道：是OG11TH的62题

A 1972 agreement between Canada and the United States reduced the amount of phosphates that municipalities had been allowed to dump into the Great Lakes

A reduced the amount of phosphates that municipalities had been allowed to dump

D reduced the amount of phosphates that municipalities are allowed to dump

我不懂这里应该用什么时态, 也是在两个答案之间徘徊.答案是D

第一题为10thOG 127，你可以翻下原OG的前人讨论

62,OG解释

Since the dumping continues into the present, the past perfect verb had been allowed should instead be the present are allowed.

第3 道：OG11th90题

The peaks of a mountain range, acting like rocks in a streamed, produce ripples in the air flowing over them; the resulting flow pattern, with crests and troughs that remain stationary although the air that forms them is moving rapidly, are known as “standing waves”

C crests and troughs that remain stationary although the air that forms them is moving rapidly, is

D stationary crests and troughs although they are formed by rapidly moving air, is

这道题我知道D应该排除，因为D中they 指代不清楚，而且用了被动语态。

但我对C还有疑问，就是crests and troughs that remain stationary和stationary crests and troughs这两个表达哪个更清楚，个人认为后者更好，还有一点是关于C中them 的指代，大家认为这个别them 指代清楚吗？我觉得还是有点模糊哦，them有可能指crests,或者是troughs,还可能是两者一起，难道C不也是有问题的吗？

carolhide，我看过解释两遍了，还是不懂，这个动作不是发生在过去吗？A 1972 agreement 也应该包括减少了过去那些人的phosphates，不是吗？

对，agreement的签署是发生在过去，但是这个协议是沿用至尽的，所以用现在时，而过去完成时的使用必须要有个明确的时间点作为完成时结束的标志，这里显然没有。

90题为10thOG 205

你去复习资料里找，有11OG与10OG的对照的，然后讨论连接里找老OG的讨论。找起来很容易，最好在复习语法前研究下置顶帖里到底有哪些好东东，这样也不会浪费时间和精力。

以下是引用llfllfllf在2006-1-16 11:31:00的发言：
呵呵,是不是我问的问题很初级啊,郁闷!我都打算2月底进考场了的

当然不是，问题没有初级高级，只要问过了记住了就好！！

大家都在讨论在成长的。

我理理句子结构啊, A 1972 agreement........reduced  the  amount of phosphates

然后后面的that 从句是修饰 phosphates, 而phosphates是municipatilities 在过去一直到现在dump的,是不是啊,这样的话别时态应该是用有延续性时态啊?这个agreement不可能只是减少 municipatilities现在dump 的数量,不是吗?
