问题 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.
选项 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
答案 B
解析 本句是“两个同级比较的平行结构”，中间用or连接，A、C、D、E都不满足平行结构的对称要求，C、D、E中的like就更不可能表同级比较，要举例也是用such as，而不用like，B中or前后“对仗”很工整，as infrequently as对应as often as；once every other month对应daily。
