I am a learner of English. Sometimes I see an article (a and the) before the noun (life) but sometimes I also see the noun without any article. So I am confused when should I use an article before the noun and when I should not. Please check the examples and let me know are they correct?
Examples:
His life is an awesome life.
I want to get a beautiful life.
I like the life he lived.
"Life" can be a countable noun.
The examples you listed above are all grammatically correct, though number 2 is little unnatural.
The expression "to get a life" does not mean to somehow obtain the state of being not dead, but rather, to do something worthwhile. For example, you can tell a person who stays at home all day to "get a life", telling him to get out and do something (get a job, find a hobby, and so on).
In your question, you mentioned being confused about the usage of an article in conjunction with "life": "Sometimes I see an article (a and the) before the noun (life) but sometimes I also see the noun without any article"
Here's my take on it :
If you were speaking about a person's or, say, a pet's life, you should use an article before the word. In other words, if you were talking about a particular life..
Eli led an exemplary life and was a great inspiration to all those around him.
Liza lived a good life before we had to put her down.
The life of a dragonfly is short but filled with action.
...and if you were talking about life in general or the very nature of life then there's no need for an article, usually.
Life can be so hard sometimes.
If life gives you lemons, squeeze them in people's eyes.
It is not the length of life, but the depth that matters.
I know it's probably more complicated than the overly simple explanation I gave above, but I thought you'd have a better understanding with a couple of examples.
+1 to @harshaKanchina, but let me add a thought:
Like many words in English, "life" has more than one definition. In this case, there is a definition that is countable and a definition that is not countable.
"Life" can mean the time between the birth and death of one individual, or the things that a person does in that time. Like, "Bob's life lasted fifty years." "Sally devoted her life to helping the poor." This definition is countable. You can say, "Ten lives were lost in the fire." "We all want lives filled with meaning."
"Life" can also mean the idea of living as opposed to non-living. "The ocean is filled with life." "All life is sacred and precious." Etc. In this sense it is not countable.
