求助大全14题

天之角

14 A migraine typically afflicts one side of the head, lasts for hours or days, and may recur as infrequently as once every other month or often, as daily.

a) as infrequently as once every other month or often, as

b) as infrequently as once every other month or as often as

c) infrequently, as often as once every other month, or often, like

d) infrequently, like once every other month, or often, like

e) infrequently, like once every other month, or as often as

大全上的答案是b。这里的比较结构我有点不懂。as infrequently as连接的是recur 和 once every other month,可是recur 和once every other month 是不同类的怎么可比呢？

如果是省略的话，记得有好多a is as...as b 的题不都是 都要把b中的动词或助动词补出来才对么？

as infrequently as once every other month ，as 连接的是infrequently和 once every other month ，都表示频率，可比较；第二个as---as是as often as金山词霸是“每当”的意思，我想在这里是表示经常的意思吧。

as as 不一定都是每当啊，也可以表比较啊

如 She is as bad-tempered as her mother(is).

支持天之角的观点不明白这个比较

jnlvo

once every other month 和daily都是时间状语修饰recur，而as infrequently as 和 as often as来修饰这个时间状语（或者就看成个副词)。

至于这个比较，也许可以这么看recur(本应有个副词修饰它, 实际省了) as often as daily. 比的是那个省的副词和daily, 这里是副词的比较，故谈不上动词或助动词补出的问题，这个问题只有在主语比较时才会涉及，主要是避免歧义和突出比较对象：是主语和主语比，而非其它如被看成宾语间的比较。

dearjane

觉得jnlvo的解释很有道理，应该是省略了一个副词。主要应该是由于这个频率即可能是“frequently”有可能是“infrequently”,所以难以找到合适的副词所以省略了

本题怎么翻译啊？

在下愚见是：偏头疼的特点是使头部的一边疼痛，这种疼会持续几小时或几天，并且可能复发——————从as infrequently。。。开始就不会翻了，请大家指教。。。

或者是不频繁的每个月复发一次，或者四很频繁的每天复发一次.
