es of people in the world but if you go to a college campus, you are sure to find at least one of every kind. The great part about being here with so many different people is that you get to interact with some interesting characters and see how to deal with them. You will meet the people you dread the most, the smart-ass, the brain, or the unique spirit, but no matter who it is that is your worst nightmare to be around you will always be paired up with them in a group project. When you get into the real world you are not going to be able to pick your boss or coworkers. Interacting with these people in college and living with different roommates will help you learn how to cooperate with the people in life you find so unpleasant. College life is fun. The fact that I have been here for a short time just means it has not yet been a life changing experience to me. If I were to give any tips on how to survive, it would not be how to survive college, but how to survive life. I would have to say that one should be outgoing and live life to the fullest. Meet new people whenever you can because they just may be a major influence in your life. Also, get your work done before you go out and party. Lastly, I would have to say, in life if you ever feel lost or alone, talk to someone about it. Everyone gets depressed at times in their life and there is always someone who will listen to your problems.

On earth gravity (引力) makes blood flow down towards the feet, so the heart must work to pump blood up. In space blood flows up towards the heart. The effect is similar to what happens when you lie with your feet up and your head down. The flowing blood is felt by receptors in the walls of arteries (动脉) in the upper part of the body and in the heart. These receptors send signals to the brain, but the brain reads them incorrectly. To the brain, the signals means the amount of blood in the body has increased, so the brain tells other parts of the body to react to the increase in the blood. For example, the body produces more urine (尿液), resulting in loss of body fluid and salt. At the same time the astronaut has less desire to drink and so does not replace the lost fluid.
As a spacecraft begins to fall back to earth atmosphere, the crew begins to feel gravity. Blood again flows towards the feet and collects there. The heart beats faster in an effort to pump enough blood to the brain. Some crew members may not get enough blood to the brain and the heart beats too fast. They become sick and even lose consciousness as their spacecraft reenters the earth atmosphere. To prevent this, special clothing is invited for astronauts to prevent blood collecting in their legs. They put it on just before the craft reenters the earth’s atmosphere. They also drink about a liter (升) of water and eat some salt to replace the fluid they have lost while in space.
Weightlessness affects the heart and blood vessels in another way. The heart does not work as hard in a weightless environment as it does in an environment of gravity. When the heart works less hard, the heart muscles become weaker. It is replaced by fibrous tissue and fat

On most space shuttle flights everyone sleeps at the same time. No one has to stay awake to watch over the spaceplane; the shuttle’s computers and the engineers at Mission Control do that. If anything goes wrong, the computers ring an alarm and the engineers call us on the radio.
On the space shuttle, sleep-time doesn’t mean nighttime. During each ninety-minute orbit the sun “rises ” and shines through our windows for about fifty minutes; then it “ sets ” as our path takes us around the dark side of the earth. To keep the sun out of our eyes, we wear black sleep masks.
It is surprisingly easy to get comfortable and fall asleep in space. Every astronaut sleeps differently. Some sleep upside down, some right side up. When it’s time to sleep, I take my bag, my sleep mask, and my tape player with earphones and float up to the flight deck. Then I crawl into the bag, and float in a sitting position just above a seat, right next to a window. Before I pull the mask down over my eyes, I relax for a while, listening to music and watching the Earth go by beneath me.
