The art of growing dwarf trees, or "bonsai"（盆景） as their Japanese planters call them, is increasing in popularity in the United States. Growing bonsai can make a fascinating hobby for anyone who enjoys plants and creating beautiful effects with them.{#blank#}1{#/blank#}．

    In growing bonsai, in fact, one must be careful in choosing the type of tree, as the growing conditions are unusual.{#blank#}2{#/blank#}．Varieties of pines with small needles and hardwood trunks are especially suitable.

    {#blank#}3{#/blank#}This is necessary because the major growth of bonsai is kept confined(被限制) to the tree's trunk and leaves, not its root system-a process quite unlike what is done with other plants.

    Another thing the bonsai-grower must do is to trim （修整） the roots and branches of the tree periodically （定期地）. Unless this is done, the plants will not have the proper proportions(比例) and will look unnatural.{#blank#}4{#/blank#}

    The last thing one must do is to be careful to keep the tree well-watered. Because bonsai are grown in smaller-than-usual containers, they often need more water than ordinary houseplants do.

    As can be seen from the above, the art of bonsai-growing is one which requires a certain amount of time and effort.{#blank#}5{#/blank#}Imagine having such a tree in your living room and passing it down through several generations of your family. That is exactly what bonsai-growing is all about: establishing a tradition of beauty which lasts for years and years and is a symbol of the beauties of the natural world.

    Exercise is a way of keeping the body healthy through being active. Another name for exercise is physical fitness. Most people exercise in their spare time. Sports are some of the most popular ways to get exercise.

    The two main kinds of exercise are aerobic exercise(有氧运动)and anaerobic exercise (无氧运动).Sports such as football and basketball are great forms of exercise. {#blank#}1{#/blank#}

    Aerobic exercise is energetic movement that lasts for a certain period of time.{#blank#}2{#/blank#}The lungs and the heart work harder to bring in extra oxygen. Swimming, cycling, running and rapid walking are good examples of aerobic exercise.

    Anaerobic exercise is a powerful burst of movement followed by a period of rest. During anaerobic exercise the muscles need more energy than the body can make with its supply of oxygen. After the exercise a person feels out of breath because the muscles have worked without oxygen.{#blank#}3{#/blank#}

    Exercise affects every part of the body in positive ways. It improves balance and coordination (协调).{#blank#}4{#/blank#}Exercise strengthens the heart and increases the lungs′ ability to take in oxygen. Through exercise the bones and muscles get stronger, and the whole body becomes healthy and strong.

    For as long as I can remember, I wanted to be a performer. But when it came time to go to college and decide what I wanted to be for the rest of my life, I didn't want to choose drama as my major. {#blank#}1{#/blank#} So instead of studying drama, I went to law school like my two sisters did before me. {#blank#}2{#/blank#} They worked about 80 hours a week, but they made good money and could afford expensive cars and apartments in the city.

    {#blank#}3{#/blank#} I had great benefits, including four weeks of vacation a year, but I never got to use any of my vacation time because there was always too much work to do. I worked from 7 a.m. to 9 p.m. six days a week, and when I finished, all I could do was get into my bed until I woke up to do it all over again the next day.

    After five years of this lifestyle, I thought I was going to go crazy. I was unhappy and exhausted, and I never saw my friends and my family. I thought that acting in a small community play might make me feel better, but rehearsals (排练) and performances all took place during my work hours. {#blank#}4{#/blank#}

    I got a small part in a local play, and then a bigger part, and then a lead role. Now I make my living from acting, and every now and then, I do some legal consulting (咨询) for a little extra money. {#blank#}5{#/blank#} I had to give up my big apartment and expensive car, but I'm so much happier now.

A. They aren't good examples to me.

B. They seemed happy enough, I thought.

C. I don't get paid a lot for my acting jobs.

D. So I made a serious decision and quit my job.

E. I am certainly a better performer than lawyer.

F. Making a living as a performer seemed impractical to me.

G. After law school, I got a good job and worked as a lawyer for a big company.

Getting the Cheapest Flights

    After interviewing 10 travel agents in the area, we've compiled (汇编) the very best tips for finding the cheapest flights.

    Book your flight 21 days before you want to fly. Booking a flight is like playing a game of chicken. Airlines want to get the most money possible for their tickets and have difficult computer programs that adjust their prices automatically. Booking too early, you might miss out on some major deals. {#blank#}1{#/blank#}The best advice is to book your flight 21 days before your planned departure date to get the best deals.

{#blank#}2{#/blank#}Most airlines update their reservation systems on Tuesday at 7 p.m. GMT. People tend to buy their tickets on weekends, so airlines make changes on one of the slowest days of the week—Tuesday.

    Fly on Tuesday or Wednesday. Tuesday and Wednesday are the least busy days at airports, and are also the cheapest days to fly. {#blank#}3{#/blank#}Friday and Sunday are the peak flying days of the week, and are the worst, and most expensive days to fly.

Book early for international flights. {#blank#}4{#/blank#}You can also try flying into smaller airports, which sometimes have better deals.

    Eat your cookies（网络标记). Delete your Internet browser cookies if you've visited an airline site within the last 30 days. {#blank#}5{#/blank#}

    Compare prices. Use travel search engines, in addition to airline websites, to make sure you're getting the best deal possible.

A. Collect it one day ahead.

B. Tuesday is the best day of the week.

C. Pay in cash when you receive your ticket.

Walking has been considered as one kind of rewarding exercise. For many people, daily walking offers massive and long-term physical and mental benefits. {#blank#}1{#/blank#} A Stanford University study found that participants were more creative when walking as opposed to sitting. 

{#blank#}2{#/blank#} You've probably heard the phrase "exercise your creativity". Our creative mindset is stirred up by physical movement, which is exactly why walking with your dog, a friend, or alone feeds creative thinking. 

But the scenery is almost as important as the sweat. Just by going outside, you are stepping out of your habitual surroundings and your comfort zone, which is necessary if you want to open your mind to new possibilities. You can walk through a tree-filled neighborhood. {#blank#}3{#/blank#} Even when you walk down a busy street, you can't help but get distracted by the sweet smells from a food cart or the child pointing to a building you haven't even noticed before. 

Walking outside develops our ability to collect new ideas and take in new sights, sounds, smells, and flavors. Shinrin-yoku, a common form of relaxation in Japan, suggests that being in the forest and walking among the trees there can lower your stress levels. {#blank#}4{#/blank#} Research has shown that getting close to nature around your neighborhood or taking a break from multimedia increases performance on a creative problem-solving task. 

So instead of setting a fitness goal, why not set a creativity goal that starts with walking outdoors? {#blank#}5{#/blank#} For example, you can turn off your phone and give yourself the chance to be present in the world, to hear conversations and natural sounds, and to notice the way people move and the way the sun reflects in a lake. 

Walk not just for exercise. Walk for wonder.

A.Unfortunately, you often fail to do it.

B.Expose yourself more to your surroundings.

C.The movement during walking is obviously key.

D.Without enough energy, you cannot wonder or create.

E.But to receive the benefits, you do not have to live in a forest.

F.This habit, however, not only benefits well-being but also contributes to innovation.

G.Wandering around a park and observing people relaxing or birds singing is also a choice.
