英语翻译
1 自从我开始学习英语已经过了6年了(since)
2 这是他第一次参加世博会（It）
3 直到完成工作他们才能离开（until）
4 在过去的十年里上海发生了很大的变化（take）
5 他看似对你刚才说的话感到很吃惊（seem）
6 非常感谢你邀请我参加为史密斯先生举办的告别聚会（farewell）

Answer 1

It has been 6 years since I learn English.

It is his first time to visit the  Expo.

They can't leave until they finish the job.

Many changes have taken place in Shanghai in the past 10 years.

It seems that he's very surprised about what you said just now.

Thank you so much for inviting me to attend the farewell which is held for Mr.Smith.
