UNIT 114 Unless As long as and provided/providing

A. Unless

Study this example situation:

The club is for members only.

You can't go in unless you are a member.

This means:

'You can't go In except if you are a member.' or 'You can go in only if you are a member.'

Unless ='except if'

Some more examples of unless:

* I'll see you tomorrow unless I have to work late. (= except if I have to work late)

* Don't tell Sue what I said unless she asks you. (= except if she asks you)

* 'Shall I tell Sue what you said?' 'Not unless she asks you.' (= only if she asks you)

* I don't like fish. I wouldn't eat it unless I was extremely hungry. (= except if I was extremely hungry)

We often use unless in warnings:

* We'll be late unless we hurry. (= except if we hurry)

* Unless you work much harder, you won't pass the exam.

* I was told I wouldn't pass the exam unless I worked harder.

Instead of unless it is often possible to say if... not:

* Don't tell Sue what I said if she doesn't ask you.

* We'll be late if we don't hurry.

B. As long as etc.

as long as or so long as All these expressions mean 'if' or 'on condition that'.

provided (that) or providing (that) All these expressions mean 'if' or 'on condition that'.

For example:

* You can use my car as long as you drive carefully.

* You can use my car so long as you drive carefully.

(= you can use my car but you must drive carefully--this is a condition)

* Travelling by car is convenient provided (that) you have somewhere to park.

* Travelling by car is convenient providing (that) you have somewhere to park.

(= but only if you have somewhere to park)

* Providing (that) she studies hard, she'll pass her exams.

* Provided (that) she studies hard, she'll pass her exams.

(= she must study hard - if she does this, she will pass)

C. When you are talking about the future, dr, not use will after unless/as long as/provided providing. Use a present tense (see also Unit 25):

* We'll be late unless we hurry. (not 'unless we will hurry')

* Providing she studies hard, she will pass the exam. (not 'providing she will study')
