58[番茄花园1] . (27510-!-item-!-188;#058&003569)

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.

(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

(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

A. 复数those不能指代单数level，因此只能强制指代前句的复数主语emissions，那么，句子变成将

level与emissions相比较，比较对象不对等

B. 正确。

C.
主语应该使用will，而不是would

D.
主语应该使用will，而不是would；复数those没有指代对象

E. 主语应该使用will，而不是would；复数they没有指代对象

句子结构：If current trend continue, … carbon emissions … will soar..., according to…条件主从复合

句。条件状语从句如果使用一般现在时，主语应该使用一般将来时

指代一致（Agreement）, 动词形式（Verb Form）

1) than/as比较结构中，名词由代词those/that指代时单复数需一致。

2) 在条件主从复合句中，条件状语从句如果使用一般现在时，主语应该使用一般将来时。句型为：

If A happens, B will happen.

1．理解句子的逻辑意思太重要了，否则看到1990；先排出will soar了

2．
That指代emissions——这里有个疑问：应该用those指代比较对象中出现的名词；that指代单数名词啊？求教牛牛

不好意思，懂了，这里是level的比较
