How to use As long as and unless
As long as
Take a look at this sentence:
"I will go if it is free."
(If it is free, I will go.)
In this sentence we can change if to as long as and it keeps the same meaning:
"I will go as long as it is free."
(As long as it is free, I will go)
Here are some other examples:
"You can borrow my bike as long as you are careful." = You can borrow my bike if you are careful.
"You will pass the test as long as you study hard." = You will pass the test if you study hard.
I will go there as long as it's free!
Unless it is free, I won't go there!
Unless
Now let's look at the same if sentence using a negative:
"If it isn't free, I won't go."
(I won't go if it isn't free.)
Here we can use unless to keep the same meaning:
"Unless it is free, I won't go."
(I won't go unless it is free.)
Unless means except if or only if.
Here are some other examples:
"I'll walk to town unless it rains." = If it doesn't rain, I'll walk to town.
"Unless we leave now, we’ll be late." = If we don't leave now, we'll be late.
"You can't enter unless you have a ticket." = Only if you have a ticket, can you enter.
