I went to Antarctica (南极) and brought back this cup of snow (but it has melted).	This hair is from a yak (牦牛) that I rode in Tibet (西藏).
I took this peach from a table in a temple (庙) on top of Tai Shan (泰山).	I bought this hotdog at a baseball (棒球) game in New York.
I used this key to attach a padlock (挂锁) to the Great Wall (万里长城).	I went to England and took this photograph of the Queen.
I took this cheese from a pizza (意大利饼) that I ate in Italy.	I took this camera to Africa, but an elephant sat on it!

On the backs of these cards should be written:

a cup of water	some hair
a peach (桃子)	a hotdog (红肠面包)
a key	a photo of an old woman
baked cheese	a camera, broken into 100 pieces

And here is an extra one, perhaps useful for a demo:

I bought these earplugs in Sydney, Australia, and wore them in the Sydney Opera House (悉尼歌剧院). I don’t like opera!

On the back should be written:
