If you finish studaying now,you can play later.如何翻译?

如果现在学习完了,过一会儿你可以去玩游戏.
If you finish studaying now,you can play later.studaying应该为to study.
finish后接动词时,不能用不定式,要用动名词,且该动名词要用一般式,不用完成式：
Have you not finished speaking?你还没讲完吗?
He hasn’t finished writing his book.他那本书还没写完.
注：当finish之后的动名词带有宾语时,有时可省去动名词(如果意义清楚的话)：
He has finished (doing) his work.他把工作做完了.
再问： 关于你指出的“应该为to study。”这一点，这句话是外国教材上的原话，所以有点小疑问。
再答： 也许我错了。 finish后接动词时，不能用不定式，要用动名词，且该动名词要用一般式，不用完成式： Have you not finished speaking? 你还没讲完吗? He hasn’t finished writing his book. 他那本书还没写完。 注：当finish之后的动名词带有宾语时，有时可省去动名词(如果意义清楚的话)： He has finished (doing) his work. 他把工作做完了
