Answer 1

Watch out for 密切注视,有“看”的意思

be careful of 珍重,注意,留意

另外,举几个watch out的例子希望你能理解如何用的：

例子：Carol's father made me promise I'd watch out for her and make sure she had whatever she needed.
2.to be aware of someone or something.小心某人某事
例子：I used to tell everyone,“Watch out for this girl.She's going to be a great tennis player one day.”
3.to be careful in order to avoid a problem.小心而避免麻烦
例子：You've got to watch out for viruses when downloading files to your computer.Watch out for that dog — he's not very friendly.
