There are many photos in the photo competition.(要用in the 而不是of)
Let me show you one of them (show you sth.或者show sth.to you 而不是for you）
a collection of photos called The Many Faces of Our City which features Beijing made by three pupils.(features不是feature,因為which代表的是一個單數(shù),動詞后面要加s.by three pupils 換成 made by three pupils純粹是要和前面的意思區(qū)別開來）
It includes photos of different parts of the city such as Siheyuan and Wangfujing.（這句話沒有錯誤,不過it includes 也可以換成it consists of,意思是這是由...組成的)
It successfully shows the rich culture of Beijing.(這句話基本是對的,successfully 也可以放在句末,意思不變.rich culture 也可以換成 amazing culture,意思是令人驚奇的文化.）
