اول از همه از همه دوستانی که به این وب لاگ لطف دارن کمال تشکر را دارم.امیدوارم مطالبی که مینویسم برای همه مفید باشد.من تمام سعی و تلاشم را میکنم تا انگلیسی را به عنوان زبان دوم به ملتم به دوستانم به همه یاد بدم.انگلیسی مهم است.چون زبان بین المللی است واگر می خواهید در زندگیتان پیشرفت کنید نیاز به ارتباط با سایر کشور ها را داری و برای این ارتباط نیاز به یک وسیله مشترک دارید و آن زبان انگلیسی است.
Unless
Study this example situation:
Joe is always listening to music. If you speak to him normally, he can’t hear you. If you
want him to hear you, you have to shout.
Joe can’t hear unless you shout.
This means: “Joe can hear only if you shout.” Unless means except if. We use unless to make an exception to something we say. .
Here are some more examples of unless:
Don’t tell Ann what I said unless she asks you. (= except if she asks you)
I’ll come tomorrow unless I have to work. (= except if I have to work)
I wouldn’t eat between meals unless I were extremely hungry. (= except if I were extremely hungry)
We often use unless in warnings:
We’ll be late unless we hurry. (= except if we hurry)
Unless you work harder, you’re not going to pass the exam. (= except
you work harder)
Instead of unless it is possible to say if. . . not.
Don’t tell Ann what I said if she doesn’t ask you.
We’ll be late if we don’t hurry.
As long as provided (that) providing (that)
these expressions mean but only if:
You can use my car as long as (or so long as) you drive carefully. (= but only if you drive carefully)
Traveling by car is convenient provided (that) you have somewhere to park. (= but only if you have somewhere to park)
Providing (that) she studies hard, she should pass the exam. (= but only if she studies hard)
When you are talking about the future, do not use will with unless, as long as, provided or providing. Use a present tense:
We’ll be late unless we hurry. (not unless we will hurry)
Providing she studies hard. . . (not providing she will study)
