You went to the beach with your friends. One of your friends got a sunburn. She says that she put on sunscreen. You think she got burned because she stayed in the sun for too long and should have put on more sunscreen.
You're supposed to reapply it every couple of hours.
Say that someone "is supposed to" do something if:
- there's a rule about it
I think we're supposed to shower before going in the pool.
- there's a custom that says something about it
You're supposed to take your shoes off when you go into someone's house in Japan.
- you have already agreed to do it
I'm supposed to pick Janelle up from school this afternoon.
"Re-" is a prefix that means to do something again. You can use this prefix to make a lot of English words like:
To "apply" sunscreen means to put it on someone (yourself or someone else).
The word "apply" sounds technical, so you would use it in situations like when you're giving someone instructions. The sunscreen bottle will probably use the word "apply" in the instructions, for example.
In more casual speech, you can use "put on" instead of "apply":
Don't forget to put on sunscreen!
You can also "apply" things other than makeup:
- Apply makeup.
- Apply a cream or ointment to a cut on your skin.
- Apply glue to something that you're trying to stick together.
- Apply a wood-sealing liquid to the wood on your porch.
Use this expression to talk about something that happens again and again after a certain length of time. For example:
I try to call them every few days, just to make sure everyone's OK.
This sentnence means that the speaker calls again and again, with 3-20 days of not calling in between each time.
