Sadly none of them correct. I have looked at the sentence you provided Jared, "If you still wash( or washing? ) the toy with water, it will be broken". 'Still' is not correct here. You need to use 'keep'. If you keep washing the toy with water, it will break.

Michael-Cx I mean: If you still wash( or washing? ) the toy with water, it will be broken. Still means to keep doing an action. However, when you add the word if to the sentence, you change this reality into a hypothetic or imagined situation. What I mean is, the situation you are describing has not actually happened but it's something you could imagine. So you could say If you wash the toy with water, you will break it. (This means that you are giving a person a warning but they haven't actually done the thing that you speak of.) You could say say: If you were washing the toy would water, it would be broke. In the second example, you entered a room and you thought your friend was washing the toy with water. But he told you that he was not using water, but a special cleaner. Then you could say, "Good! Because if you were washing the toy with water, it would have been broken."

Still is used to say an action or situation continues to the present because it has not finished. It often refers to something happening for longer than expected. Notice the position of still before the verb or adjective. •My grandfather is sixty-nine and he still works every day at the kiosk he owns. •Do you still live with your parents? •It's 8pm, and I can't leave the office because I still have work to do. •Are you still angry with your partner? •He is still asleep so don't wake him up. If the verb has two parts, still goes between both the verbs: •She started her exam an hour ago and she is still answering the questions. •Is it still snowing? (= it continues to snow, it hasn't stopped) •When I went to bed, Angelica was still working. But if one of the two verbs is negative, still goes before that negative verb: •Lucy has stopped smoking but her brother still hasn't quit. •I took the clock to the repair shop though it still isn't working.

Well, none of these are for "can be," but are for "to be." If you still wash If you are still washing If you are washing still Are both correct depending on the sentence. For "can be:" If you can still wash If you still can wash It is more common to put still *before* the word you are modifying (still washing), but you will hear English speakers say "washing still" sometimes and it is also correct.

Michael, 都不行啊! 这是什么? 睡一个好觉然后再继续努力吧，你现在太不在状态了。
