Chores were not popular at my house. My children didn’t like to do chores. They always saw me do chores, but they hardly ever helped me do them.

A year ago, I made a game called “The Endless Chore Game”. It is really great. Here’s how the game works.

I make a card with forty squares (方框), and I write a different chore on each square. These chores can be easy and interesting like making dessert. Then my family rolls the dice (骰子) to decide what chores we have to do. The card also has a few squares with fun things, like watching TV and singing. If you are lucky, you can watch TV when the others are doing the chores.

My son likes the game very much. He goes to the kitchen happily every morning to do the game. It is really a good way to make my children do chores. You can have a try if you have the same problem with me.

Astronauts have to solve two problems: how to get food and how to keep their spaceship clean. They need to solve them in order to stay alive. They are in a spaceship far from Earth, and they need to take care of everything themselves. They need to be sure they have what they need to live there, because the astronauts may be in space for weeks.

Here is how they solved the food problem. At first, the astronauts took tubes of semi-liquid (半流质的) food with them into space. They look like the toothpaste you use when you brush your teeth. The food did not taste great, but because astronauts did not need to take dishes with them,   they had no dishes to wash.

Today’s spaceships have a bigger menu. Astronauts can eat from bowls. In fact, they take cereal (谷类食物) and other foods with them. The foods are kept in a special way to stay fresh.

They have a kitchen on the spaceship. Its oven can heat food to 170 degrees. The kitchen has water and sets of meals that come on plates. The astronauts choose their menu before they go into space. They take a lot of food with them.

How do they keep the kitchen clean? They do not have to worry about mice or other rodents (啮齿类动物). They make sure that there are no rodents before the ship leaves. But sometimes mice travel on the ship. Those mice are part of experiments. They live in cages.

How do astronauts keep their plates clean? That is another health problem the astronauts solve. They need to stay healthy in space. To carry a lot of water to wash plates would be much heavier. They take wet wipes (湿巾) in bags. They use them to clean plates. So, their kitchen is clean and they stay healthy.
