When astronauts are in space, they eat, sleep, wash, work and play. 3 They do the same things as us, but they do them differently. 

On Earth, we put food on a plate and water in a glass. Gravity (引力) holds the food down and keeps the water in the glass. But in space, there is almost no gravity. So food can float(漂浮) away, and astronauts must eat and drink carefully.

Sleeping is very difficult in space. Some astronauts like to float in the air, but most like to be in a sleeping bag. They tie（拴）the flag to a wall so that they don’t float away in the night.

Washing is difficult. There is no shower or bath, so astronauts must use a sponge(海绵), They brush their teeth normally: they don’t want wet toothpaste to float around the spacecraft! 

Exercise is very important in space. On Earth, your legs carry your body, but in space, astronauts float, so they do not use their legs. 4 This is very bad for their legs, so they must exercise for thirty minutes every day. They often use an exercise bicycle for this.

After a day’s work, astronauts relax. They may listen to music, read, watch films, play games, or talk to their friends and families by radio. On the International Space Station, astronauts sometimes race from one end of the station to the other. The most popular pastime is looking out of the window, looking at the space and watching the Earth.

It is known that most people spend one third of their lives sleeping. So sleeping is important to our health and daily lives. But the problem is that for most people, especially office workers, it is not easy to get enough sleep. For centuries, people have been troubled by insomnia. There are three ways to deal with it

Pay attention to your daily diet!

How well you sleep is closely connected to your daily diet. If you eat fat or hard-to-digest food for supper or eat just before you sleep, it will keep keeping you awake. What should be on your daily menu? For supper, you can choose something low-fat and digestible like fish, chicken or lean meat, rice and wheat. All the foods mentioned above can soothe the nerves(舒缓神经). Avoid foods that cause gas such as potato, corn, bread, carbonic acid(碳酸)drinks. If you still can not sleep well after cutting out these harmful foods, try adding some foods that will make you sleepy

Create a good sleeping environment

A good sleeping environment includes comfortable pajamas, a soft quilt, and most importantly, a comfortable bed.

Do something relaxing

In order to get a good night's sleep, you should not only relax your body, but also your mind. Try to do something to relax your mind before going to bed. Listening to soft music, reading or watching some light TV for half an hour before going to bed is a good way to make you feel sleepy. If you still can't sleep, try some exercise like walking or jogging to get rid of stress and increase your blood circulation(血液循环). Also taking a bath or soaking（浸泡）your feet in warm water can help your blood circulation and relax your body.

Ms X leaves home at 6:00 in the morning. She spends an hour and a half in the traffic and arrived at her workplace already tired at 8:00. At lunch time, she stands in a line and in the end finds there are no sandwiches left! On the way home she is in the traffic again and arrives home tired at 7:00. There is just time to cook something simple, watch an hour of TV and then have an early night.

Ms Y gets up at 7:00 and goes for a run or does some exercise. After breakfast, she sits down to work at 8:30 in the office at the top of her house.

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:

1.The writer thinks many people probably misunderstand the word“activity” to be “_______”.  

A．physical activity	B．body movement
C．sports hall exercise	D．outdoor exercise

2.When exercising, the most important fact is ________.

A．the time spent on exercise

B．the intensity of activity

C．the difficulty of exercise

D．the right balance of activity

3.The author advises dividing activity into shorter exercise breaks because ___.

A．exercising for a long time is bad for people’s health

B．it has the same effect as soccer practice

C．people usually haven’t much time to exercise

D．no one can spare lots of time to exercise

4.What’s the best title for this passage?

A．Regular exercise.	B．School exercise.
C．Indoor exercise.	D．Difficult exercise
