第一句感觉怪怪的
Could you please talk about the rescue?可是网上有好多这样的句子，can you talk something about ....口语没关系啊可以用 talk something about sth都可以用 say something about sth替代的也就是说在口语中没关系，考试中就要选第二个。侧重点稍有不同talk something about 谈论关于……的事say something about 说出关于……的事 say/talk something about yourself 都是自我介绍下的意思 （意思大体上是一样的）
