Benefits of Cross-Country Skiing
Cross-country skiing can be enjoyed by a wide range of students, from the youngest kindergartners to those secondary students. It is really a fun activity, providing students a gentle workout outside in winter. While having fun, students can gain physical and mental benefits.
The physical benefits of cross-country skiing are well known. If we look at Olympic cross- country skiers, we can see the positive effects on the body that result from training for cross-country skiing. The average best female cross-country skier carries 11 percent body fat, and best male skiers carry 5 percent. These percentages are well below the average for people who are considered to be athletic — 17 percent for females and 10 percent for males. The high number of calories burned while skiing helps to keep skiers slim in a healthy and attractive way.
Cross-country skiing is also an efficient way to exercise a large number of muscles at once. Because skiers use ski poles as a means of propulsion, the force that drives skiers forward, the upper body gets much more of workout. Of course, the leg muscles also do their fair share. People who use cross-country skiing as a workout over several weeks will discover that the muscles of their entire body increase in strength.
Cross-country skiing on a regular basis has a tremendous effect on a person’s cardiovascular system.
In addition to gaining strength in the muscles of the upper and lower body, people who use cross-country skiing as a workout method over several weeks will also discover that their heart is stronger. A strong heart pumps more efficiently, sending out more blood to the muscles with each contraction(收缩). Through weeks of skiing, people often discover that their resting heart rate has decreased. Highly trained Olympic cross-country skiers have resting heart rates between 28 and 40 beats per minute. Compare that to the resting heart rate of the average person, which is 60 to 80 beats per minute!
The benefits of cross-country skiing extend beyond overall general health. A lot of evidence exists indicating that regular physical activity increases the release of mood-lifting endorphins (内啡肽) in the body. After one of the energetic and fun skiing lessons, students will be smiling and laughing; they will be relaxed and in a better mood than when they started class. Students will leave class with a sense of accomplishment, knowing that they have developed new skills in a fun activity.
Cross-country skiing is a great way to work the total body. Now more and more students are taking part in this exercise outside during the winter months. They are enjoying it and benefiting from it!

We’re often being told how self-driving can will reward US With almost unimaginable benefits when they finally hit the streets. Aside from the convenience of being chauffeured (私人司机) everywhere by artificial intelligence ( AI), there’s the safety factor, not to mention how environmentally friendly driver-less electric vehicles could be. But there’s also another advantage—parking. It’s one that could have a vast impact on the look, feel, and function of the cities, and it could thoroughly change the crowded urban spaces.
“We aren’t going to need parking, definitely not in the places we have it now,” Alain L. Komhauser, a researcher at Princeton University, told Patrick Sisson at Curbed. “Having parking close to where people spend time is going to be a thing of the past. If I’m at the office, it doesn’t need to be there.” The extreme case of totally empty car parks and city streets with no stationary (静止的) vehicles would probably require people to fully let go of personal car ownership.
“Car sharing is already reducing the need for parking spaces,” Carlo Ratti told Curbed. “Self-driving vehicles will strengthen this trend and have a dramatic effect on urban life, because they will blur (使模糊) the distinction between private and public modes of transportation,” he added. “‘Your’car could give you a lift to work in the morning and then, rather than sitting useless in a parking lot, give a lift to someone else in your neighbourhood，social-media community, or city.”
In that case, we needn’t park our cars. They’ll park by themselves, so we would see a huge increase in the width of sidewalks, bike lanes, and space for any other kind of transportation.
In all likelihood, we won’t see these kinds of changes happening very soon. But it’s exciting to think of the benefits this technology could bring.
1.Why do the author mention the often-told advantages of self-driving cars?
A. To draw a conclusion. B. To make a comparison.
C. To analyze the underlying reasons. D. To introduce the topic.
2.How can we achieve zero parking in cities?
A. By producing more eco-friendly electric cars.
B. By selling public vehicles to personal owners.
C. By promoting car-sharing with self-driving vehicles.
D. By allowing only self-driving vehicles to run on roads.
3.What will happen if we needn’t park our cars?
A. More people will walk to work.
B. Public transportation will shrink.
C. Urban areas will be less crowded.
D. We needn’t spend money on transportation.
4.What attitude does the author have towards self-driving technology?
A. Indifferent. B. Favorable.
C. Ambiguous. D. Disapproving.

Benefits of Reading
The benefits of reading start with the first book a baby hears and continue into childhood and throughout the child’s life. Here are some reasons why reading is important.
Reading teaches children about the world around them. 1.They are exposed to ways of life, ideas and beliefs about the world which may be different from those which surround them. This builds a store of background knowledge, which helps younger children learn to read confidently.
2.When we read, our brains translate the descriptions we read of people , places and things into pictures. When we are reading a story, we are also imagining how the characters are feeling. We use our own experiences to imagine how we would feel in the same situation
Children who read do better at school. And they don’t just do better at subjects like reading, English and history. 3.
Reading is a great form of entertainment! A paperback book or an e-reader doesn’t take up much space so you can take it anywhere and you’ll never be lonely or bored if you have a book in your bag. 4.
Reading relaxes the body and calms the mind. 5.The constant movement, flashing lights and noise are quite stressful for our brains. When we read in silence, the black print on a white page is much less stressful for our eyes and brains.
A. Reading improves concentration.
B. Reading develops a child’s imagination.
c. We seem to have forgotten how to relax and how to be silent.
D. Children learn new words and greatly enlarge their vocabulary.
E. They do better at all subjects and they do better all the day through school.
F. You can read while waiting for a friend or during a flight delay at an airport.
G. By reading, children learn about people, places and events outside their own experience.
