Dear Mary,
We are holding a picture exhibition at 2:30pm on the coming Saturday. There will be different kinds of Chinese Picutres. Jacky Cheung will sing many songs at the exhibition. There will be a lucky draw so vistors will have opportunity to receive prizes. If you are interested in the exhibition, you can contact me at xxxxxxxxx for booking ticket.
Yours,
Steven
我知道are holding意思係寫封信之前我地預先決定會舉行畫展,同埋計劃埋係畫展裏面有咩野活動,我咁樣理解岩唔岩。同埋想問下篇野既tense岩唔岩。
