I love listening to music and there’s never been a better time to be a music fan. With so many ways to get music, we can listen to it any way we want, wherever we want. Although some fans still like to use CD players, the most popular way to listen to music nowadays is by either downloading (下载) or streaming (在线试听).

As Internet connections got better, more MP3s were downloaded and shared. But the sound quality of these MP3s is not so good when compared to tapes or CDs. However, new generations (代) of music fans have grown used to this cheapened sound quality and don’t mind.

Streaming technology has made it even easier to listen to your favorite music. For a monthly price of about $10 (there are also free services with advertisements), users can listen to an endless amount of music from smartphones, computers and television sets.

Unfortunately, streaming is not without its downsides. Because all of the music is provided online, a strong Internet connection is necessary. And although it may seem like the Internet is available everywhere, there may be situations where you don’t get connected. Agreements with music companies and artists also need to be reached before streaming services are allowed to host their music.

Whether you choose to download or stream music, the artist does not make much money. The low payment from downloading and streaming music has also led to the continuing increase in concert ticket prices. And we can only expect these prices to increase greatly in the future.

Much as I would like to have all my music for free, I realize that it will kill the industry I’ve enjoyed for most of my life. I can’t say for certain which is better — downloading or streaming — but I do know how I can do my little part to help musicians continue making great music. Rather than focus on (关注) one or the other, I’m going to continue doing what I’ve been doing since I first discovered music: listen to it any way I can.

Passenger pigeons (旅鸽) were the most common birds in all of North America in the 1800s. It was common to see large groups of passenger pigeons — groups that made a sound like a storm. But today, they are extinct because of human behavior. Now, some scientists want to bring passenger pigeons back to life by using new technology and scientific ideas. They call this process de-extinction.

De-extinction has not happened yet. It is still just an idea. The process of de-extinction is not easy. First, scientists must collect DNA from the bodies of extinct animals. Then they will put it in the eggs of similar animal species. When these animals become adults, they will have babies. And these baby animals will have the DNA of the extinct animals.

Scientists believe it is possible to bring back passenger pigeons and many other animals. However, not everyone thinks this is a good idea.

Stuart Primm is the world’s leading expert on modern animal extinction. He believes that bringing extinct animals back to life is bad for the earth. On one hand, these animals no longer have a safe place to live. On the other hand, they could cause other animals to die.

Many other scientists do not agree with Stuart Primm. Stuart Brand, a writer and scientist, is one of them. He believes de-extinction is good for many reasons.

“The current generation (当代) of children will experience the return of some unusual animals in their lifetime. It may be part of what defines their generation and their attitude to the natural world. They will take their parents to zoos to see the growing populations of passenger pigeons, and maybe even dodo birds. This will provide a good deal of money for zoos busy with extinct species restoration (恢复). Humans killed off a lot of species over the last 10,000 years. So, it’s right to bring some back to life,” he said.

 When something goes wrong, it can be very satisfying to say, “Well, itˈs so-and-soˈs fault.” Or “I know Iˈm late, itˈs not my fault; the car broke down.” It is probably not your fault, but once you form the habit of blaming somebody or something else for a bad situation, you are a loser. You have no power and could do nothing that helps change the situation. However, you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation. This is the winnerˈs key to success.

Winners are great at overcoming problems. For example, if you were late because your car broke down, maybe you need to have your car examined more regularly. Or, you might start to carry along with you the useful phone numbers, so you could call for help when in need, For another example, if your colleague causes you problems on the job for lack of responsibility or ability, find ways of dealing with his irresponsibility or inability rather than simply blame the person . Ask to work with a different person, or donˈt rely on this person. You should accept that the person is not reliable and find creative ways to work successfully regardless of how your colleague fails to do his job well.

This is what being a winner is all about----creatively using your skills and talents so that you are successful no matter what happens. Winners donˈt have fewer problems in their lives; they have just as many difficult situations to face as anybody else. They are just better at seeing those problems as challenges and opportunities to develop their own talents. So, stop focusing on “Whose fault it is.” Once you are confident about your power over bad situations, problems are just the stepping stone for success.

Many of us live with a roommate at times. Sometimes, there can be problems. Who hasn't had an argument about whose turn it is to take out the trash, or who should be the one to dear up after dinner? However, living with another person also comes with many benefits.

    You know that there's always someone else around that can help you feel safer. There's always someone to talk to, so you need never be lonely. Beside a these obvious benefits, there are some you may not notice. For example, we're actually more likely to eat healthier food when living with others.

    To examine the effect of living alone, Australian university researchers did much research and found that people living alone tended to eat less fresh food including fruits and vegetables, which can have side effects on long-term health. However, those living with others generally got benefits from a more varied diet compared to those living alone.

    What could explain this? The researchers believe the social and cultural roles played by cooking, food preparation and eating may be important considerations, those living with friends have someone else to go shopping with, and thus, they are more likely to buy higher-quality fresh food regularly.

    Cooking skills may be another factor. If people living alone find they don't have the knowledge required to prepare a particular dish or cook a certain food, they may fall back on ready-made, less healthy food. However, if they live with at least one other person, they may be able to ask for help.

    In addition, people living alone can eat want at any time of the day. However, it's helpful to have someone around who questions your decision to eat frozen pizza at 3:00 am. In other words, roommates can draw your attention to such an unhealthy routine.

    So, if you now live alone, fighting a losing battle against poor eating habits, why not consider sharing a home with someone rise?"

Happiness is what everyone looks for.   (1)  someone says that he is happy. However,   (2)  makes him happy may not work for others. And even  (3)   , someone may spend all his life looking for happiness, but in vain.

In the past, I tried my best to make myself happy. I thought if I could   (4)   get and do what I wanted to,  I would be happy. Certainly, it was  (5)  , but I was disappointed. Though I could be happy at  (6)   , I couldn’t keep my happiness for a long time. Why?

One day, when I told a friend of mine what I  (7)   about happiness, he smiled and said only a few words “Happiness is not a   (8)  thing but a by-product ( 副产品). ”

I was surprised, but he was really  (9)  .

One of our expectations about education is that it will pay off in terms of upward mobility. Historically, the relation between education and income has been strong. But in the early 1970s, a contradiction developed between education and the economy. Our value of education and our average educational attainment（获得）run faster than the capacity of the economy to absorb the graduates.

Since the 1970s, high-school graduates have experienced a striking decrease in earnings, making them the first generation since World WarⅡ to face a lower standard of living than their parents had. Experts have argued that this contradiction is at the heart of the problem of public education today. It is not, as business leaders claim, that the schools are failing to properly educate students, that they are turning out young people who are inadequately prepared to function in the workplace. The real problem is a shortage of economic opportunities for students who are not continuing on to college. College graduates also are having difficulty finding jobs. Even when they do, the jobs may not be consistent with their training and expectations. Part of the problem is that too many young Americans expect to have professional jobs, making disappointment and frustration unavoidable for some.

Many students assumed that what was true of an individual— that the higher the education, the better the job opportunities — would also be true for an entire society. But when the numbers of better-educated young people became too great, the economy could no longer absorb them. Another part of the problem is the assumption that greater educational attainment guarantees career advancement. In fact, employers do not routinely reward educational attainment; rather, they reward it only when they believe it will contribute to the employee’s productivity.

We should not overlook the fact that there is still a strong relationship between education and occupation and income. College graduates have a strong advantage over those with less education. But the payoff is neither as large nor as certain as it once was. Unfortunately, Americans have focused so strong on the economic payoff that many consider their college education useless if it does not create a desirable, well-paying job. Only in this sense can we speak of an “oversupply” of college graduates. 

We could argue that all or at least the majority of Americans would profit by some degree because higher education can enable the individual to think more deeply, explore more widely, and enjoy a greater range of experiences.

There are so many ways to make new friends such as joining a sports team, taking part in community activities, or traveling. And there is no doubt that a friend in need is a friend indeed because they can help you out when you are in trouble or encourage you when you are frustrated(沮丧的). So, joining a sports team will be my first choice.

The primary reason for this is that everyone in a sports team has the same interest, which is the most fundamental（基础的）） character for friends. Because of it, they will become your potential friends so that the chance to be the true friends is very high. In addition, the same interest can give you a lot of topics to talk with your friends in daily conversation.

  Another factor that should be taken into consideration is the memory. After you fight for a goal with your partners, it will leave you a good experience, which is necessary for a long-lasting friendship. I used to be a player in the basketball team for my high school. Even though it was five years ago, I will well remember all exciting moments when we fought for the championship as if they happened yesterday. And although we went to different universities, we get together so many times.

  In addition, trust is also an important aspect. As we know, keeping trust is the most important thing in the team because it can make you be together all the time. Furthermore, you can share happiness and sadness with reliable friends and they will make you feel life is beautiful and future is bright.

In a word, joining a sports team can reinforce the relationship between you and your partners. For it, joining a sports team, maybe your new friends are waiting for you.

We are enrolled in the full-time school called “life”. Every day in this school, we have opportunities to learn new lessons. No matter whether we like these lessons or not, we have to take them, because they are our lessons.

Why are we here in this world? What is the purpose of life? Humans have tried to discover the meaning of life for thousands of years, but failed to get the answer, because the meaning of life is different from person to person.

Each one of us has his or her special purpose and path, unique and different. As we travel on our life path, we will learn many great lessons in order to fulfill that purpose. Learning our lessons well is the key to discovering the real meaning of our own life.

As we travel through our lifetime, we may be taught hard lessons that others don’t have to face, while others spend years struggling with problems we don’t need to deal with. We may never know why we love English, not physics, which indicates that our path is different. While traveling on our own path, sometimes alone, we should, first of all, take a basic lesson in openness.

Openness means being receptive. Life will present us with so many lessons, none of which are useful to us unless we can recognize them and are open to their values. These lessons are not easy to learn, but we should regard them as gifts. But how can we recognize these lessons? It is a matter of what “glasses” we are wearing at the time. It is not difficult to spot them if we take them as opportunities. So when we are not open to learning our lessons, failing a weekly English test might be like a disaster rather than an opportunity to us. Of course, the hard lessons may not be fun, but they can actually be the biggest gifts we receive from life.
