Do you like fast food? Why or why not? 你會怎麼回答這題？

(X) Yes, I do. Because it’s convenient and fast and cheap.

(O) Absolutely, hamburgers are actually nutritious. A burger gives your all the nutrient intake you need. For example, carbohydrates from the bread, protein from the meat, fiber from the lettuce, a bit of fat from the slice of cheese. So, I love it.
