It is so difficult to get 5.5 in exam of IELTS(The International English Language Testing System) for me.Because I [非大寫不可]want to study in Canada in this fall,so i have and therefore need to get a 5.5 score in exam of IELTS for before a Canadian visa can be issued.__but Now I feel that my English is so poor.  I don't know many English words so much, and I know that I need to study more. words,but It is not easy.because since I can don't remember well and forget words easily. at the same time, In fact I have been studying English since I  was ten. 10 years old ,but i hardly studied hard.__Obviously,_so low level of english I must not have been studying hard - hence the poor level of English I have today.

After I had decided to go to Canada,_I started to study English very hard, but I still very worry much about the exam result.  of exam,Although a 5.5 this score is not so high, but [有了 although, even though, though, since etc, 不须用 but] I'm afraid of score that it won't will be not enough.__because I just know these basic words; I just can write these simple sentences.__In a word, I have no confidence.

能用简单詞句表白思想非易. 是英文文章高峰!  看你文章中, 不知你是懶惰或不知, 例如英文的我非大寫不可. 符号用法不确, 單符後定要一空位等等, 考官一看就不会浪費他時間...
