And it is the first draft. so it is not well-written. Hope you can give me some advice on my topic or grammar.
Just because it is your first draft, does not mean it does not have to be well written. Since you yourself have admitted that it is not well written, then I wont comment on the grammar. You can submit a revised version, and perhaps reading over that will be better.
*From the first sentence, I knew where you going.
When you said this: 'In my dictionary, the word CONFIDENCE had never existed.
I had a feeling you would refer to this in the ending. So i decided to scroll down and check.
Ultimately, the word Confidence is engraved on the cover of my dictionary of life.
Bingo. I was right. Its a sign that perhaps, you should be more creative so that your essay is more powerful and more striking to it's readers.
I then skim read the main body. Wow. Your significant experience was seeing a butterfly and then comparing yourself to it.
You are no Thomas Hardy, and it is quite unlikely that you saw inspiration from a 'Darkling Thrush', or a butterfly in your case. Ok fine, maybe you did.
. Consequently, the sound of others' ridicule, the ambivalence of my bet, the picture of my hardworking all floated through my mind like a real film. Ultimately, all the images folded up into a beautiful butterfly flying freely in the sky. I raised up my head. Hundreds of eyes stared at me.
^I am sorry, but that just sounds too fabricated to me.
Also, the conversation part:
"Hey, did you hear that Alice that weird girl will attend the WHC this march?"
"Yeah, I was so surprised how such an inexperienced and taciturn person could attend this important competition."
"How did the teacher make the decision? She was sure to hinder our school performance."
"Haha, Let's just wait and see."
^It kind of sounds as if you just typed it up, rather than quote the exact words of those people.
Basically, I kind of get the impression that this essay is a bit fake. As it is fake, it fails to impress me.
