It’s cold and dark outside, and your bed is so warm and comfortable. Going for a run seems like such a bad idea. But before you hide your running shoes, it might be worth giving that crazy idea a go.

According to The Huffington Post, an outdoor run in winter, as opposed to one on a treadmill (跑步机), burns more calories because the body is working hard to regulate (调节) its core temperature. Furthermore, research shows that race times are faster in cold weather than in warmer temperatures—and quicker runs burn more calories. Similarly, cold weather also makes the heart work harder to distribute blood through the body, making that vital muscle even stronger.

Outdoor exercise also turns up your energy and rids you of the stress and depression that build up every day. The heat and humidity in the summer can drag you down and tire you faster, but cold weather is refreshing. It adjusts you to your surroundings, making you feel alive.

Of course, the threat of smog in some built-up areas is a further hurdle to winter exercise. Heart attacks, stroke, lung cancer and asthma are all dangers of running in smog. The combination of air pollution and exercise increases the potential problems. If you do choose to run outside on smoggy days, take a path in a park or residential area to avoid car exhaust (尾气), and go early in the morning, before rush hour. But staying inside on smoggy days and waiting for the next clear day to run is best.

1.How does cold weather benefit runners, compared with warm weather?

A. They can run more slowly.

B. They can take in more calories.

C. Their hearts can function harder.

D. Their body temperature can get lower.

2.How does summer affect runners?

A. It builds up their energy quickly. B. It makes runners tired easily.

C. It lessens runners’ stress. D. It causes heart attack.

3.What are the runners supposed to do on smoggy days?

A. Stop driving cars. B. Do more exercise.

C. Avoid outdoor exercise. D. Run late in the morning.

4.What can be the best title of the text?

A. Refresh with a Winter Run B. Take Outdoor Exercise in Summer

C. Go to Run in a Park D. Follow the Tips to Reduce Stress

Now many young people are traveling around the world on their own, not because they have no one to travel with, but because they prefer to go alone.

Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.

In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen, it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.

Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website, The Aussie Nomad, to document his adventures. He says he wished he had traveled alone earlier. “The people you meet, the places you visit, or the things you do, everything is up to you and it forces you to grow as a person,” said the 30-year-old man.

Richardson describes traveling alone like “a shot in the arm”, which “makes you a more confident person that is ready to deal with anything”. He said, “The feeling of having overcome something on my own is a major part of what drives me each day when I’m dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”

The great 19th century explorer John Muir once said, “Only by going alone in silence can one truly get into the heart of the wilderness.”

1.Which of the following will Kristina Wegscheider agree with?

A. Traveling alone is a necessary experience for everyone.

B. It is more meaningful to travel in foreign countries.

C. It is comfortable to travel around without a friend.

D. Traveling abroad helps people to find new things.

2.Traveling alone is challenging because ________.

A. you have to make things on your own

B. it is hard for you to prove yourself to others

C. you can only depend on yourself whatever happens

D. it will finally build your character

3.What can we infer about Chris Richardson?

A. He started traveling alone at an early age.

B. He was once shot in the arm.

C. He used to work as a salesman.

D. His website inspires others a lot.

4.What is the best title for the passage?

A. Travel Abroad B. Travel Alone

C. Travel Light D. Travel Wide and Far

Most episodes of absent-minded-forgetting where you left something or wondering why you just entered a room—are caused by a simple lack of attention, says Schacter. “You’re supposed to remember something, but you haven’t encoded it deeply.”

Encoding, Schacter explains, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situation. If you put your mobile phone in a pocket, for example, and don’t pay attention to what you did because you’re involved in a conversation, you’ll probably forget that the phone is in the jacket now hanging in your wardrobe(衣柜). “Your memory itself isn’t failing you,” says Schacter, “Rather, you didn’t give your memory system the information it needed.”

Lack of interest can also lead to absent-mindedness. “A man who recite sports statistics from 30 years ago,” says Zelinski, “may not remember to drop a letter in the mailbox.” Women have slightly better memories than men, possibly because they are more interested in what’s happening around them, and memory relies on just that.

Visual cues(提示) can help prevent absent-mindedness, says Schacter. “But be sure the cue is clear and available,” he cautions. If you want to remember to take a medication with lunch, put the bill bottle on the kitchen table—don’t leave it in the medicine chest and write yourself a note that you keep in a pocket.

Another common episode of absent-mindedness: walking into a room and wondering why you’re there. Most likely, you were thinking about something else. “Everyone does this from time to time,” says Zelinski. The best thing to do is to return to where you were before entering the room, and you’ll likely remember.

A. Writing notes. B. Taking some medicine.

C. Putting something in sight. D. Returning to where you were.
