 آموزش گرامر -حرف تعریف نامعین

(Indefinite article)

حرف تعریف نامعین شامل a و an می‌باشد.

حرف تعریف a قبل از یك حرف بی‌صدا بکار می‌رود:

a car, a man, a bus, a house

حرف تعریف an قبل از یک حرف صدادار (a,e,i,o,u) بکار می‌رود:

an apple, an actor, an animal, an old man

 ٍExamples:
We've been to Paris.  He hasn't lived in Paris. Have you met him yet?چند نکته
1- در کلماتی مانند honest، hour، honour و ... حرف h تلفظ نمی‌شود (غیر ملفوظ)، بنابراین همراه با آنها حرف تعریف an مورد استفاده قرار می‌گیرد:

an hour, an honourable man

2- كلماتی مانند useful، unit، university، union، European و ... با اینکه با حروف صدادار شروع می‌شوند، ولی حرف اولیه آنها مانند «you» تلفظ می‌شود. بنابراین آنها با حرف تعریف a مورد استفاده قرار می‌گیرند:

a university, a useful book

a یا an تنها قبل از اسامی مفرد قابل شمارش می‌آیند:

a book, a happy boy, a famous actor

برای اسامی جمع، بجای a یا an، یا از some استفاده می‌کنیم و یا اصلاً هیچ کلمه‌ای را بکار نمی‌بریم:

  • It's a cat.  It's a dog.  And it's a monkey.
    but: These are all animals.

  • a horse,  some horses

My developer is trying to persuade me to move to .net from PHP.
I have always disliked the idea because of the expenses.
But he's tryiong none the less. I've been using WordPress on numerous websites for about a year
and am anxious about switching to another platform.
I have heard fantastic things about blogengine.net. Is there
a way I can transfer all my wordpress content into it?
Any help would be really appreciated!

First of all I would like to say great blog! I had a quick question in which I'd
like to ask if you don't mind. I was curious to find out how you center yourself and clear
your mind prior to writing. I've had trouble clearing my thoughts
in getting my thoughts out. I do take pleasure in writing however it just seems like
the first 10 to 15 minutes tend to be wasted just trying to figure out how to begin. Any recommendations
or hints? Thanks!

When I initially commented I clicked the "Notify me when new comments are added" checkbox and now each time a comment is added I get four emails with the same comment.
Is there any way you can remove people from that service?
Thanks!
