Spoken English always bother me

I have learned English for about ten years.But i still can't use English correctly,especially spoken English.Now, my work involves English.I need to go aboard about three times each year to participate in expo. When i introduce our product to customer, i always get too nervous to speak . I always forget some easy words.So it's a big problem for me. The problem has been bothering me for a long time.

It seems to me like you're quite fluent with written English. The person above was right. You have to practice speaking with someone whom you are comfortable with. Finding a native speaker is easy but finding someone whom you can easily talk to is very crucial. If you wanted to practice it, you have to abandon a little bit of your privacy and talk with another English speaker using a video call :)

Take part in the EMC training

Today, we had a training for the EMC, the trainer had done a very good job, but i almost fell asleep, i felt a little bit guilty, i need learn to more every day in the future.
(今天， 公司有个培训是关于EMC的，培训师讲的很好，但是我差不多睡着了，我感觉有点内疚，我需要今后每天学习更多.）

i said i was sad ^___^ very sad.
