1、求翻译
2、求语法分析

Answer 1

外国人常说：that's it.表示,就是这样了.
前面的句子告诉了你谈话内容,后面的句子说that's pretty much it,意思是对话差不多就是这样了,没有什么其他内容了.
非要详细分析的话,是个句型倒装结构,调整过来之后应该是：it was pretty much that.it 指代 conversation,所以最后的句子差不多是这样的：
The conversation is pretty much that we exchanged a few more comments on the weather,which was wet.
另外后面这个it做形式宾语
大概意思就是说我们经常和别人聊一些关于天气的东西，这就是我们和别人寒暄的东西了
