LINKING WORDSSo and but are used to join 2 sentences. They are

informal and typical of spoken English.Ex: It was raining, so we decided to stay home.

UNLESS

• Unless means the same as if… not. Unless is not used in questions.Ex: + I can’t see if I don’t wear glasses.

I can’t see unless I wear glasses.+ He wouldn’t say that if he wasn’t sure

about it. He wouldn’t say that unless he was sure about it.

14/12/2008 Ho Dinh VanNguyen Thi Van

With unless, we use present tenses when we talk about the future.Ex: Unless it rains, I’ll pick you up at 6.00.(not Unless it will rain….)

In most real conditional sentences, can use either unless or if…not with a similar meaning.

14/12/2008 Ho Dinh VanNguyen Thi Van

However, we use if…not but not unless:+ In most unreal conditional sentences:

Ex: He would be happier if he didn’t take things so seriously.(not….unless he took…)

+ When we talk about emotions:Ex: I’ll be amazed if Christie doesn’t win.(not...unless Christie won…)

+ In most questions:Ex: If you don’t pass the test, what will you do?(not Unless you pass…)
