They can do it beautifully.   In the USA, people drink tea at breakfast or after meals. They usually use tea bags to make their tea. Making tea with tea bags is faster and easier than making it with tea leaves in teapots.

One day, you open the fridge and find some mold (发霉的) food. But before you throw it away, your mother stops you. She doesn’t want to waste (浪费) food. She cuts off the molds part and eats the rest. Is it safe to do this?
