What do you do if you're stranded (处于困境的) on a lonely island? Surely you need to find a way to get in touch with the outside world. Your best chance of doing this is to draw the attention of a passing plane.

Body signals (信号)

Pilots from different countries understand body signals if they have the correct training. When you wave your arms up and down in a straight line, it means "yes". When you point downwards and swing your arm from side to side, it means "no". If you want the pilot to know that it's safe to land, push your hands out in front of you and bend (弯曲) your knees. If you want to say that it's not safe to land, put your arms in the air and move them to one side.

Smoke signals

The smoke from a fire can be seen from far away, so it's a good way to draw attention. If the weather is dry, it isn't hard to start a fire. Remember, however, that fires can be very dangerous if they get out of control. Never light a fire unless you're sure that it can't spread. If the ground is dark, light smoke can be seen more easily. Green grass and leaves produce light smoke.

Ground-to-air signals

It's a good idea to build some signals, too. Use large pieces of wood to make the symbols (标记). If you can't find any wood, use earth. Some useful symbols are:

F: I need food and water."

II: I need medicine."

I: I am badly hurt."

X: I am unable to move from here."

Pilots' replies

If the pilot lowers the plane's wings from side to side, this means "message received and understood". (At night, the pilot flashes the plane's green lights.) If the pilots flies the plane in a clockwise circle, this means "message received but not understood". (At night, the pilot flashes the plane's red lights.)

Sometimes parents wonder if they should really give their children chores (家务活). After all, isn’t it the parents’ responsibility to manage the household? And don’t children need an opportunity to “just be children” for now because they have the rest of their lives to worry about chores?

Most children have really busy schedules. They rush around from one activity to another with little time to clean the house. Despite those concerns, however, giving your children chores may be one of the most important things you’ll ever do.

While giving your children chores can certainly take some of the stress off you, that’s not the only reason you should expect your children to do the chores. Studies show chores are good for children. Research from a well-known 75-year Harvard study shows that chores can shape children to be more likely to become happy, healthy and independent adults.

Why are chores like sweeping the floor and clearing the table so important to children’s happiness in life? One reason is that children feel a sense of achievement when they do their chores. No matter whether they’re making their beds or they’re sweeping the floor, helping out around the house makes children feel capable. Doing chores also helps children feel like they’re part of the team and learn responsibility. Helping family members is good for them and it encourages them to be good adults.

Children who do chores gain important life skills that will serve them well throughout their lives. Life skills such as meal preparation, mowing the lawn, or doing the laundry will be important after high school, which helps your children live independently.
