Question

一个关于口语的问题
like the old saying goes about teaching an old dog new tricks,that is sometimes harder for an older person to change,but they can do it.
这是练口语的材料上的一句话.我想问的是：为什么goes后面还要加about,“like the old saying goes”不就可以表达“就像老话说的”了吗.还有后面的“but they can do it”感觉怪怪的.

Answer 1

那个old saying 如果后面跟的是原话就可以不用about了
可是那不是原话,那是大概意思,这个old saying 还不完整呢
还有最后“but they can do it”是强调结果
无论如何,无论多困难,他们还是可以学会的
