What are you going to do if you are in a burning house? How will you escape? Do you know how to save yourself? Please read the following passage.
Escaping a fire is a serious matter. Knowing what to do during a fire can save yourself. It is important to know the ways you can use and to show them to everyone in the family, such as stairways (楼梯) and fire escapes, but not lifts.
From the lower floors of the buildings, escaping through windows is possible, learn the best way of leaving through windows with the least chance of serious injury (伤害).
The second floor window is usually not very high from the ground. An average person, hanging by the finger-tips (手指尖) will have a drop of about six feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way than to stay in a burning building.
Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked (泄露) into the room.
On a second or third floor, the best windows for escape are those which open onto a roof (屋顶). From the roof a person can drop to the ground more safely. Dropping onto cement (水泥) might end in injury. Bushes and grass can help to break a fall.

Astronauts, people who fly into space, need special training. First they go to Houston, Texas. That is the home of the Johnson Space Centre. There they are tested to see how strong and smart they are.

One of the first tests is for the heart. The people walk or run, then the space doctors see how fast their hearts are beating.

Another important test is performed. In this test the person must curl（蜷曲）his body up in a ball. When he is in that position, he is put into a round cloth bag. The doctors give him no idea how long he will have to stay in the bag. If a spaceship broke down in space, the astronauts would get into bags like this. Then they would have to wait and curl up in darkness, until help could arrive. You can see that an astronaut must not be afraid of tight space or darkness.

After the tests, only the best people are chosen to start astronaut training in a training centre. The astronauts in training learn many other things. They learn how to jump out of a moving airplane. They learn to how to blow up a lifeboat and get into it while they are in the ocean. The astronauts also have to learn how to get lifted out of the ocean by helicopter（直升机）. That may look fun, but it can be dangerous.

After they finish training, the astronauts continue to work. They stay in good shape by running and doing exercise. They read about their special jobs. In that way they can learn new facts about space travel.

Then the big day comes. The astronaut is told to go to work on a flight into space. The crew members（全体船员）get to know each other first. Then they can learn which job each will do.
