以下句子是从<综合一>里的抄录下来的原句子:Once a weekly study plan is prepared ,follow the same pattern every week with samall changes.此句中,Follow the same .....是Prepared的伴随状语.但我认为Follow后面应该加ing,大家认为呢?

1.此句中,Follow the same .....不是Prepared的伴随状语. 如果前边是状语，后边也是状语，那就不叫句子了；
2.once引导条件状语从句，后边应该是主句，省略了主语(you/we can )，当然也可看作祈使句。
如：
Once you enter the lab, follow the teacner's instructions.

Once it is lit, it will continue to burn.

Once it is touched, never hope to give it up.
