I like watching China's hunan TV show "I am singer" (I don't know if that's really the name of the show, but I would say "I am a singer")

The program has seven star singers. Everyone will sing a song. ( I would say "Everyone sings a song" or "Everyone gets to sing a song or two..." 
Then the different age groups of the audience vote。( I find no fault in this sentence, but for you to have other options, I would have put it like this: "After all the singers have finished, the audience, which is separated in several groups by age, vote for their favorite singer." )
The less eliminated。 ( This sentence has a problem, you can express that idea like this: "The singer with less votes is eliminated." or "The singer with the fewest votes is eliminated each week or after each show...")
I feel wonderful and stimulus. ( I would say it like this: "Each time I watch the show, I feel wonderful and exhilarated." Stimulated isn't used as often, I guess, so I would use exhilarated or elated. Or just very happy, or enthused. 

I like a singer in this Show.
Her name is Shila. Her eyes are very beautifu.I like her very much.

Good job! Keep up the good work.
