First,I want to say "thank you " （雙引號(hào)里面第一個(gè)字母最好用大寫）for （to）you (and wish want you to) still stay with me.
Formerly,I had many firends who had (去掉had) promiss(+ed) me to keep firendship forever.
But I find（注意時(shí)態(tài),你總不能一直都發(fā)現(xiàn)這個(gè)吧）（加個(gè)that會(huì)好點(diǎn)） none （of them）stay with me when I go farther and farther.（整段都注意時(shí)態(tài)）
Now,I just have you.So I want to thank you again and again!
You let me know what is firend（you let me know about what friend means）,what is firendship(what friendship is/means).
You let me know,to have a good firend and have firendship are very beaytifly tings.
I don't konw,does I'm (am I)a friend of qualified in your heart?
But I'm sure (that)you are a good friend.
I think ,a good firend can help you study and encourage each other to make progrees instade bring (你不發(fā)現(xiàn)這里有兩個(gè)謂語動(dòng)詞了么)trables.
A good firend can share your happiness and sadniess（sadness）.
The most important（用副詞+ly）,a good firend who is always believe you.（不能成句,只有主語.你可以改成the most impotant thing is that a good friend always believes you）
And he or she will try his or her （their）best to understande （沒有e） you instead find（instead of finding） your fault.
However,these you are done(被動(dòng)語態(tài)?你被做了?).
You will appear to comfort me when I （am）sad;You will laugh（smile） with me when I （am）happy.You （have）stuy （ied）with me already have（去掉） four years .
although I'm not the qualities of a good firend,I'll try my best to do it well!Until like you treat me .
I hope ,our four-year（形容詞） firendship can cntinue the next（more than） four years and four years .
My privilege to have you !(擁有了你?)
Dear,Don't leave me .Bcause Without your accompany,I walk really lonely.
Best wish !
說實(shí)話,初二水平……不過感情真摯!（冒昧問一下,你初幾?）
加油吧!
辛苦你了,也累壞我了~
