An astronaut’s work may sound exciting, but living in space isn’t as fun as you think. The website www.space.com lists the disadvantages of living in space. Here are some of them.

When astronauts work outside the station during spacewalks, they have to wear special gloves. The gloves are very tight. They can hurt the astronauts’ fingernails(手指甲) and even make them fall off.

In space, you don’t have many choices in what you eat. It’s hard to get fresh fruits and vegetables. It is not OK to eat bread because it leaves crumbs(碎屑). Crumbs could fly around everywhere.

In space, it is impossible to have a good shower because water can fly all over the ship and break the machines. Astronauts have to use a special water-shooting(噴水) gun and a washcloth.

Astronauts lose their bone strength quickly during their stay in space. So far, there is no way to solve this problem. They do exercise while they’re in space to try to keep their bones strong as long as possible.

Perhaps the hardest part of life in space is the feeling of loneliness. Astronauts sometimes have to spend weeks and even months away from Earth. They miss their friends and families.

None of us is quite as healthy in mind as we seem, but neither is every unusual thing we do means we’re unhealthy. How to tell the difference? Start by reading the letters below, which have been analyzed by our experts.

(1) Lately, after I read an unusual word, I often can’t get it out of my head for days, sometimes weeks. I silently repeat it to myself, often spell it, and even wake up in the night with it ringing in my head. What’s wrong with my brain?

That sounds like a little obsession (著迷). Your brain feels that for some reason it must repeat this word. Unless it is taking up more than an hour of your day or really influencing your life, it is not serious. To stop it, leave it alone. If you really want to stop the repetition, set aside ten minutes a day to repeat the word over and over again. Do it so many times that you finally get sick of it.

(2) I sometimes have strange dreams when taking a short sleep, and I think they’re real when I wake up. Then, as I come around, I realize they aren’t. Is there something wrong with me?

What’s wrong is that you take short sleeps and most of us don’t! But are you mad? No. We all have strange dreams, and it’s normal, upon waking, to be fuzzy (模糊) for a little while or even not to remember where we are. What is not normal is if you don’t have these dreams.

(3) When people are eating, I can’t stand the sound of a fork or spoon knocking on a plate or bowl. I begin shaking and having a headache. I’m also sickened by the sound of people chewing with their mouths open. Is there something wrong with me?

It seems that there is something wrong with everyone else you know. How come they don’t eat with their mouths closed? At the least, you’re over sensitive (敏感) to little noise. You may also be troubled by a disorder in mind called misophonia. Try drawing your attention away from the noise. Pay attention to something else as hard as you can when you eat with your friends: the music in the background, the scene out the window, even what they’re talking about. You can train yourself to be less troubled by the noise.

(4) When I’m driving and have to cross a bridge, my heart starts racing and I feel light-headed. The fear that I’m going to pass out makes the whole situation worse. Am I crazy?

This sounds like an anxiety (憂慮), which can bring on heart illness and a real sense that you’re going to die. This kind of feeling is the body’s reaction to the possible danger in near future. To keep your anxiety from progressing, try the old method: breathing. When you feel your heart starting to race, take a deep breath in three or four times, and then let it out five or six times until you start to feel comfortable. You can also make a tape of your favourite song, and sing along as you cross the bridge.

A. The first two.                                                 B. No. 1 and No. 3.

C.       The last two.                                           D. No. 2 and No. 4.

58. What can we do when we have strange dreams after a short sleep?

A. It’s not necessary for us to do anything.

B. We can think about the dreams once again.

C. It’s a good idea to pay attention to other things.

D. We’d better go to see a doctor as early as possible.
