选B，回复看看答案。
看比较对象是什么，该题逻辑上应该是婴儿死亡率的现在和过去对比。

但是E应该更清楚吧。。

E的结构表明该题是主语the rate比较，但该题不存在宾语有歧义的情况，不用补出was，was是多余的。此外，lz你想想the rate was 后面其实没有与前面的平行结构可以补出，不可能是The infant mortality rate is presently lower than the rate was lower ever before.

此外，E 再次重复the rate,多余，整个结构与B相比awkward。B的结构明显比E清晰很多，表示过去和现在这两种状态的对比。

谢谢！
但是我想进一步问下比较级+than 之后有时候必须加those、 that之类的这个怎么判断啊？

答案选B，E错了，不是the rate was ever before, 是 the rate ever before

为什么D不对？
FROM RON：
1) VERB TENSE SHIFT
if there is a change in verb tense between the two halves of the comparison, then you MUST include the verb in both halves. (if the verb is omitted in the second part of the comparison, then the implication is that the tense is the same in both halves.)
so: Heating-oil prices are expected to be higher this year than they were last year --> correct
BUT if you wrote： Heating-oil prices are expected to be higher this year than last year--> incorrect
since there must be a tense shift between what is happening this year and what happened last year.
这里说了有tense shift的话，应该要补出动词的，那这题里省掉的it has been和前面的is不是tense shift吗？
我觉得应该是"The infant mortality rate has decreased steadily over the past decades and is now lower than it has been ever before."
求解释
