1. I have been there and done it.
This is actually an abbreviation. The complete sentence is: I have been there and I have done it. I've been in the sea, seen everything and done everything. The implication is that you don't come with me, I am an old driver! Example:
If that's your attitude towards Las Vegas, then maybe it's time to try a different vacation spot.
If you have such an attitude towards Las Vegas and look for a needle in a haystack, you may need to change your holiday destination. )
2. Trial and error.
The original meaning refers to a methodology: trial and error. In other words, it is allowed to make mistakes in the process of trying, learn from them, continue to improve, and continue to try until the final success. Example:
There is no immediate solution, it is just a trial and error process.
There is no panacea that can be cured immediately-it can only be a process of trial and error. )
3. Innate and acquired.
It is the "congenital and acquired" of China people. These two words are not only similar in form, but also have alliteration and rhyme, which sounds beautiful. Example:
