I am a total noob when it comes to Chinese, so sorry if this is a dumb question. Recently I started using an Anki deck called SpoonFedChinese to study Chinese. Today I came across the following sentence (the translation is the one given in the deck):
Is there anything I should do?
Now, I know 有什么事 means "is there anything", 我该做 means "I should do", and 吗 is the question marker, but I'm still not sure what purpose 是...的 serves in this sentence. Could you have the sentence without this structure? If yes, then how does it change the meaning?
Thank you in advance.
