Some Difficulties I Met When Learning English

I have studied English for more than ten (10) years in school. I thought my English was (is) really good and that I had (,have) no trouble in reading, listening and (,) writing, but recently (lately) I found I was wrong. My English is not that good, just so-so. Hence, a lot of work is  still needed. (Lots of knowledge still needed to learn.)

Thanks to italki, (ITALK,) I have found many interesting things to do here, such as (on ITALK.) communicate (communicating) with many others (people) who are (were) also trying hard to learn / to improve their (in learning) English. Speaking with others on Skype, Wechat,or QQ, I just try to explain what happens in my daily life by translating from (tried to translate) my native (language) Chinese into English. (,told than what I though,what I met that day. Trying hard to let them understood what I said,what I meant.)

Great, keep up the good work. I have made a few suggestions to make your article read a little more natural in places.
