邀請信英文怎麼寫 邀請外教老師一起參觀一個藝術展，可以簡單說明邀請原因，需要詳細介紹展覽的內容，並交待清楚展覽的時間跟地點。?

Dear Sir. (Dear別隨便用，國外無所謂尊師重道，若你真的認為老師是你長輩，就用Dear sir吧，若你認為老師如同你朋友，用名字才是最親切的稱謂)
Because we know you have been eager to see some art exhibitions in city, and now here is the opportunity.
There is an art exhibition in downtown.
Since Chinese technology shows (意思不明確，是否為traditional skills show) are considered beautiful and attractive, and more and more people are interested in arts and crafts, and because of this reason, our city will hold an exhibition in the art museum on July 15.
The exhibition, enriched by flowers, features the works of 50 influential artists from all over the country.
Many of the art works on display are attractive, from which you can enjoy the fine art works.
It would be great if you could come, and I’m looking forward to seeing your affirmative reply.
Best wishes,
Ann
