In many countries, grandparents, parents and kids all live together.

In Australia, many kids live in a big family. The family is not just Mom, Dad and the kids in the house. Grandparents are the parents of your mom and dad. So that means (意味着) you may have two grandmothers and two grandfathers.

If you live with your grandparents, you are lucky that you get to see them very often. You may have someone who can tell you “family stories”. You may have someone to talk with about your worries. If you don’t live with your grandparents, you can call them or write letters to them.

Your grandparents may be living in “your” house but you should ask their permission (允许) to go into their room or use their things.

Sometimes you feel very good with grandparents, and sometimes you feel bad. But there is a lot of fun with them. So please be good with them.

Household (家庭) waste is a kind of waste which is created in everyday life. It includes broken dishes, used paper, banana or apple peels, and so on. Some of the household waste is not harmful while others can be.

A busy household can create a great deal of waste. And the amount (量) of household waste can increase quickly, especially in countries which depend heavily on packaging (包装) for products. Many families like to deal with their waste by simply burning it or putting it underground. These ways can be dangerous because they have a bad influence on the environment.

So how should you correctly deal with your household waste? Firstly, before throwing away something, think about whether it can be used again. Generally, paper, glass and bottles can be broken down and reused. Then, put harmful household waste into different rubbish bins.

Secondly, record how much waste you create. You can weigh your household waste every day or every few days and record the amount for several months. It can sometimes be a surprising experience. Even people who think they have a small number of rubbish bins find that they create a lot of waste. Then they may be encouraged to try to create less waste.

Besides, dealing with household waste also, needs governments’ efforts. Nowadays, many governments have paid attention to the problem of such waste. And they have come up with many ideas to solve it.
