By simply shuffling your legs while walking forward in the water, most stingrays will do their best to get out of the way.

A, by simply shuffling your legs while walking forward in the water, all stingrays will do

B, while simply shuffling your legs, bla bla

C, with simply shuffling your legs ... bla bla

D, If you simply shuffle your legs when you are walking forwared in the water, most stingrays will do their .

E, simply shuffling your legs as you are walking in the water, all stingrays wll try

我在AE犹豫，所以其他选项记不清了，我选的A。估计错了。不知道有没有do ones best这说。

(Notes: 我觉得这里用介词引导的从句，shuffle 的主语就成了stingrays. Stingrays 是一种小鱼明显不可能shuffle your legs,然后再do their best to get out of the way。我认为如果大家如碰到这题，不妨注意一下有没有用if 或者while 等引导，且shuffle的主语是人的答案, 比如something like: while you shuffle your legs as walking forward in the water, all stingrays.

我补充了D选项，应为我选D，所以记得比较清楚.不知道对错。
