Singapore is not a city.It is an island nation岛国
A cat is an animal
August is a month
Monday is a day
It is high up in the sky and comes out at night .moon
You use your mouth to eat
An apple is a kind of fruit
A clock tells us the time.
We alaways hear it at the MTR stations:Please stand behind the yellow/(safety) line.
