Today I will join a meeting

Two of my collegues from US came to China, our chinese collegues will have a meeting with them, but I am a little nervous, because of my poor English. My spoken english and oral english are not good.

oral=spoken, so "My spoken english and listening skills are not good"

I cannot always understand what they say. I am not confident for in myself. I don't know many English words, they are stranger to me. eg, Today I remember a new word, the next day, I forget it. Another situation is that: I master some words, and I know their meaning, but when someone talks with them, I can not catch what they were saying. Help, Help.

Like everything, to practice often is more important than to practice for long times.

if you wait 1 day between practices, you forget 10%. If you wait 1 week between practices, you have forgotten 90%. Put another way, 10 mins each day is much better than 70 mins once a week.

btw, your written english is very good :)
