实在找不到答案 大家帮忙在这里解释一下

对第一题我是这么看的

GWD里有一道题目是:

The Organization of Petroleum Exporting Countries (OPEC) had long been expected to announce a reduction in output to bolster sagging oil prices, but officials of the organization just recently announced that the group will pare daily production by 1.5 million barrels by the beginning of next year only if non-OPEC nations, including Norway, Mexico, and Russia, trim output by a total of 500,000 barrels a day.

即only if does,XXX will,

由if 引导的条件句

本题变成了if only should be...XXX would be

open to discuss哈

if only because:如果仅仅因为，如果仅仅考虑

如果仅仅考虑重复建设应该被避免，在州间共享地带建立大型医院就算一种资源浪费。

even if they can afford表示他们（多半）已经买了，在买了情况下，household labor还是demanding才奇怪。

even if they could afford表示他们有那个钱，可是没买，在这种情况下，household labor还是demanding就不奇怪了，不奇怪干嘛要用even if来表示强调或者惊讶的语气呢？没必要。

对的，第一第二题，我也是用if A happens, B will happen.. 这里的 A,B和happens可以换
