If you get lost, this is what you should do. Sit down and stay where you are. Don’t try to find your friends—let them find you. You can help them find you by staying in one place. There is another way to help your friends or other people to find you. You can shout or whistle （吹口哨）three times. Stop. Then shout or whistle three times again. Any signal（信号）for three times is a call for help.

Keep up shouting or whistling. Always three times together. When people hear you, they will know that you are not just making a noise for fun. They will let you know that they have heard your signal. They will give you two shouts or two whistles. When a signal is given twice, it is an answer to a call for help.

If you don’t think that you will get help before night comes, try to make a little house with branches（树枝. Make yourself a bed with leaves and grass.

When you need some water, you have to leave your little branch house to look for it. Don’t just walk away. Pick off small branches and drop them as you walk in order to go back again easily. When you are lost, the most important thing to do is to stay in one place.

The keys to reaching or staying at a healthy weight are regular exercise and good eating habits. Teens should get 60 minutes or more of physical activity a day. Note the word “activity”. As long as you’re getting your body moving, it doesn’t have to mean doing difficult exercise or going to the sports hall every day. All that matters is that each week you get the right balance of activity, including aerobics (有氧运动), strength building, and flexibility (柔韧) exercise. Make exercise a habit by arranging some time every day.
On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more. But most of us are busy, and 60 minutes a day for exercise seems like a lot of time. The good news is that it’s OK to divide it into shorter exercise breaks throughout the day.
Just as you might have a healthy snack to stop yourself from getting hungry, exercise snacks can keep energy levels high. So get up 15 minutes early and do some stretching (伸展) activity. Walk fast or run slowly for 15 minutes after lunch. Do the same thing after school — or walk or bike home. Add to that taking the stairs, PE class, and walking between classes during the day, and you’ve probably reached your 60 minutes.
Here are five simple ways to make an exercise lifestyle change:
【小题1】The writer thinks many people probably misunderstand the word“activity” to be “_______”.

?
The building is shaking. A woman with a baby in her arms is trying to open the door, but fails. Finding no way, she rushes into her bedroom and there they survive  the earthquake. ?
In a factory building, as the workshop floor swings under the terrible shaking, workers run for safety. Some hide(隐藏) under the machines and  survive , but others who try to run outside are killed by the falling ceilings.?
These scenes, played by actors and actresses, are from a film of science education 《Making a Split Second Decision》  shown in 1998 on China Central TV in memory of Tangshan Earthquake.
