If you get into the forest with your friends, stay with them always. If you don’t, you may get lost. If you really 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 by staying in one place.

There is another way to help your friends or other nearby people to find you. Give them a signal (信号) by shouting or whistling (吹口哨) three times. Any signal given 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 noise for fun. They will let you know that they have heard your signal. They give you two shouts, two whistles, or two gun-shots (枪声). When someone gives you a signal, 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---cover up to the holes with branches (树枝) with lots of leaves. Make yourself a soft bed with leaves and grass.

What should you do if you get hungry or need drinking water? You would have to leave your little house to look for a river. Don’t just walk away. Pick off small branches and drop them as you walk so that you can find your way back. The most important thing to do when you are lost is—stay in one place.

Are you a morning person? You might not like the findings in this new research.

From a lack of air and drinking water to solar radiation, theoretical Mars pioneers face any number of potential obstacles to settling on the red planet. Now, scientists have found something else to add to the list: seriously messed-up biological clocks.

One day on Mars - which scientists refer to as the solar day, or“sol”- is 37 minutes longer than a day on Earth. A team of European scientists recently demonstrated why that could be a problem.

Circadian rhythms are the body’s natural cycles of rest and waking, which tend to follow roughly 24-hour light-dark cycles. These natural rhythms - which play a role in biological functions including brain wave activity and hormone production - can be interrupted by things like jet lag（时差）and night shift work.

For the study, the researchers compared mice with healthy, 24-hour circadian clocks to mice with a genetic change that caused them to have shorter, 20-hour circadian clocks. The mice with healthy biological clocks were more likely to survive and reproduce, while the mice with shorter biological clocks were more likely to die off.

What does this all have to do with space travel? Since the Martian sol is longer than a day on Earth, people with shorter circadian clocks could suffer from health problems as they try to adapt to the rotational speed of the red planet.

Unfortunately, the body is unlikely to adapt to the new conditions or“learn”to develop a longer clock. As Loudon explained,“Learning is not a likely option.”

In other words: Sorry, super-early risers - NASA might not want you for the next Mars mission.

1.From the passage, people can face the following troubles living on Mars EXCEPT ______.

A. absence of air　　 B. a lot of fierce creatures

C. lack of drinking water　　 D. messed-up biological clocks

2.According to scientists, how long does one day on Mars last?

A. 24 hours.　　 B. 23 hours and 23 minutes.

C. 24 hours and 37 minutes.　　 D. 12 hours and 37 minutes.

3.How did the researchers study what effect living on Mars has on sleep?

A. By comparing different mice.　　 B. By analyzing computer data.

C. By experiments in spaceships.　　 D. By observing and judging.

4.Life on Mars would seriously mess with your sleep because ________.

A. the brain wave activity will be interrupted

B. the body’s natural cycles can be shortened

C. hormone production will hurt biological functions

D. the Martian sol is longer than a day on Earth
