同意前面两位老师的解答!我觉得根据require这个动词的搭配特点,as required可以有不止一种补全方式。

1. 根据 require sb to do sth 这一搭配,我们可以将其作如下补全:

Do exercise as often as (you are) required (to).

2. 根据 require that-clause 以及 it is required that-clause 这一搭配,我们可以将其作如下补全:

Do exercise as often as (it is) required (that you should (do)).

类似的用法再如 as expected。如:

He didn’t do his work as well as expected.

补全方式一:

He didn’t do his work as well as (he was) expected (to).

补全方式二:

He didn’t do his work as well as (it was) expected (that he would).

Do exercise as often as required.

【答】在as 之后省略了is,完整的表达是:Do exercise as often as is required.

我认为,“比较代词”as 替代整个主句的内容,相当于that you do exercise often. 只有这样理解,require 才讲得通:We require that you do exercise often.

Do exercise as often as is required. 不同于 Do exercise as often as I do it.  因为在as I do it中,省略的“比较对应项”是often,由as充当。完整的说法是:I do it often.

补全后的比较分句是:

Do exercise as often as it is required that you should (do). as作为比较代词,替代了频度副词aften,在that从句中作频度状语。
