Look after 和 take care of 有什么区别？如果难以说明的话，请教我一下例句。

'Look after' can suggest to keep someone from trouble, watching over them, attending to their basic needs such as hunger and shelter, as a sort of guardian. 'Take care of' perhaps has a more maternal feel to it in the sense of protection, love in certain contexts, and of course, care. For example, a mother may say to a babysitter regarding her baby "Look after him" to say 'make sure that he is OK for when I am gone'. A mother that has to leave her baby behind with her sister as she is leaving for a long time may say "Take care of him" to say 'love him and protect him as much as I would'. I guess a mother wouldn't be expectant of a babysitter to love her child, unless she is rather protective, in which case she would say "Take care of him" to the babysitter too.

Sure! Look after tends to be used in reference to children but can also be used for other people who require assistance of some kind. Take care of has multiple meanings, though. I need to look after my little sister. I need to take care of my grandmother. He’s looking after his elderly father. She’s got to take care of her kids today. Will he be able to take care of your mom while she’s ill?

Take care of can also be used to refer to things that need doing. The car needs washing. Can you take care of that? Would you mind taking care of the paperwork for that transaction?

Yes that’s correct.

Look after can also mean “deal with”, but we don’t really use it that way in the US. I think it’s more of a UK thing. A British person might say: Your roof appears to be leaking. You’d better look after that.
