Bored with your life？Dreaming of something different？When I feel like that I look up and wonder what life would be like 400km above my head.That's where the International Space Station orbits the Earth，with six astronauts who travels into space on board for months at a time.
How do they sleep？They spend the night floating in a sleeping bag inside a small separate room on the ceiling.American astronaut Sunita Williams explains： "It's like a little phone booth but it's pretty comfortable and it doesn't matter if I turn over and sleep upside down.I don't have any feeling in my head that tells me I'm upside down."
Brushing your teeth in a place where you can't have a tap or a sink can be a challenge.Can you imagine the mess that running water would make in weightlessness.Canadian astronaut Chris Hadfield uses a straw to put a big blob（團） of water from a sealed bag onto an ordinary toothbrush and adds a little toothpaste to clean his teeth-which he has to swallow when he's done.
Daily exercise is of great importance.The weightlessness makes bones easier to break and muscles lose strength - so spacemen are encouraged to work out for at least two hours a day.
The role of spacemen in the International Space Station is to act as lab technicians for scientists back on Earth.So they spend their time preserving their environment and performing and monitoring experiments in a confined（有限的） space about the size of a Boeing 747.Almost every task is carefully planned by mission control -although most astronauts spend their first days losing stuff until they get used to sticking everything they use to the walls.
One of their most valued privileges is the view from"the office"，ruled by that huge blue ball down there，sitting in the darkness of space.Wow!Absolutely breathtaking!

Not only is laughter good for the soul，it is also good for the brain and can help improve your memory．

2．Winter is often bitterly cold，which often makes us stay indoors more instead of heading out to exercise．Worse still，there are many viruses doing their best to make you sick．And sneezing，coughing and nose blowing make the rooms a habitat for viruses． （1）

Wash your hands
You pick up viruses everywhere and they live on your hands，so wash your hands and do it often．（2）But if that's not available，use an alcohol-based hand sanitizer （消毒殺菌劑）．

3．What is cross country running？Cross country is an outdoor endurance（耐久性）sport that can be mentally challenging and fun.（1）
You're not only putting one foot in front of the other；you're also thinking ahead to barriers and changes in the trail or course.
（2）However，before you begin training and racing，you should be aware of potential injuries and how to avoid them.How can you prevent cross country running injuries？The best ways for outdoor runners to stay healthy include the following running tips：
Stretch daily.For all runners and athletes，a regular stretching routine is an important part of conditioning.（3）
Warm up and cool down.Muscles and tendons（跟腱）are less likely to overstretch or tear if they've been properly prepared for running and racing.High-intensity workouts require more prep and post-workout cool down than low-impact activities.
Wear the right shoes.Make sure your shoes fit properly and that they are neither too tight-fitting nor too loose.（4）
Eat and drink enough.Competitive distance runners like to keep their weight low.However，consuming too few calories can harm your body，especially if you're a girl or woman subject to eating disorders.（5）It's effective to prevent injury and heat illness.Remember that especially in full sun or in humid regions of the state，you particularly tend to have heat stroke.Drink plenty of water before and after running.
A.Cross country running is a sport requiring money.
B.Tie double-knots to prevent tripping over undone laces.
C.It's mostly very safe in comparison to other team sports.
D.Have a well-balanced diet and be sure to stay well-hydrated.
E.You may encounter unexpected，non-natural barriers.
F.It is needed to keep your bones，joints，and muscles healthy.
G.This type of running and racing has both a physical and psychological role.發(fā)布：2025/1/1 15:30:1組卷：3引用：2難度：0.5
