What can I say? 这是一种表达方式，用于在特定场合下不知道该说什么才合适。它也可以表示一种无奈，比如“我还能说什么呢？”或者“我不知道该说什么了”。"I don't know what to say" 另一种表达方式，用于真正不知道如何回答某个问题，比如在课堂上回答问题，或者对一个难以正面回答的问题做出含糊其辞的回应。For example:A: What do you think about that party?B: Well, I don't know what to say... it was just okay.A: Why didn't you go swimming with us?B: Because my mom didn't agree, what could I say...Both sentences are similar, but there is a subtle difference. The key is to watch more American TV shows to understand the nuances between common phrases. This is just my interpretation...
