题目：
If current trends continue, by the year 2010 carbon emissions in the United States will soar to a level more than one-third higher than were those in 1990, according to official projections.
选项:
A、will soar to a level more than one-third higher than were those
B、will soar to a level more than one-third higher than that
C、would soar to a level more than one-third higher than it was
D、would soar to a level more than one-third higher than those
E、would soar to a level more than one-third higher than they were
答案:
B
提问：
这句话主语是emissions吧，为什么可以用that呢，选的e
问题：1.感觉应该是something is at the level，而且前面是复数，所以用they were。
2. would感觉更好一些因为前面有一点假设的意思。

提问：
If…表示结果还没有发生，所以would比will好，所以排除了AB；又因为1990年的carbon emissions 和2010年的emissions 不是指同一个东西，所以排除了CE，选了D。
