雅思口语话题答案：Describe a number you like.

I like the number ten. In sports, something that scores perfectly is a perfect ten. A person who is attractive and physically flawless is often said to be a ten, from the idea of ranking that person's appearance and sex-appeal on a 1-to-10 scale. Counting from one to ten before speaking is often done in order to cool one's temper. In science, 10 is the atomic number of neon. It is also the number of carbon atoms in decane, a hydrocarbon, the number of hydrogen atoms in butane, a hydrocarbon and the number of spacetime dimensions in some superstring theories. It is the number of provinces of Canada. It is the number of 10 Downing Street. In religion, there are the Ten Commandments and the Ten Plagues of Egypt.
I like the number ten because it's just perfect for me.
