What's wrong with my English?

I have spent a lot of many a time on learning English. but why However, my English exams always turned me down? results are not to me. Why? the My English teacher always give me such low scores on my writing!? Was Did I makeing too many mistakes? I am dying to know the reason! how and why? I have a very high scores on listening and reading. but it Alas, I am suprised me when I looked at my score in for writing section. Today's is not a good day! I am a bit off-colour pissed today.

As you can see from the corrections, you now know why such a low score on writing.  To be able to write well is different from understanding and reading.  I can understand what you wrote but... Reading is nothing but just reguritation of sounds on a written piece of paper.  You don't have to understand what you read unless you are asked questions afterwards.  

When one cannot face the truth, one can never learn and improve.  Your teacher is giving you the best reality to buckle yourself to study harder.  Do not listen to others.  It will forever keep you from soaring into the clouds like an eagle but to behave like some lowly chicken on the farmyard.

Remember 忠言逆耳 and 天下無難事,只怕有心人?

Because you asked and based on the small writing sample you provided, your low English scores are most likely due to your errors using verb tenses, punctuation, and contruction of phrases. 

I don't have a degree in English, but for example, one way of correcting your sample written text above, would be as follows:

I have spent a lot of time learning english and yet, my written english exams are low.

Why did the teacher give me such low scores on my writing? Did I make too many mistakes? I'm dying to know how and why. I have high scores on listening and reading, but my written score surprised me.
