After I mastered my first (协奏曲) at age 14, my parents decided to get me a nice violin. I tried out dozens of instruments before I found my match: a German violin. It was beautiful, but what I liked best about it was its voice. Confident and strong, it was everything I longed to be.

    I'm not sure how much that violin cost, but my parents made me promise never to let it out of my sight. They didn't understand that dragging a large violin case ran counter to my daily middle school task of being invisible (看不见的). I was a strange, absent-minded kid. When I spoke up in class, my comments brought confused silence from teachers and wild laughter from students. Like a deer in a wolf pack, I tried to be quiet and still.

    In contrast, my new violin was almost shockingly loud. Together, we could drown out the rest of my middle school orchestra(管弦乐队) — which was encouraged, since the other kids made sounds like cats' crying. For one glorious hour every day, I was showered with attention. Everyone wanted to hear what I had to say.

    Between classes, I bent under the combined weight of my violin case and a backpack filled with books. My posture suffered, but my confidence grew. With my violin by my side, I found my voice. More and more, I contributed to class discussions and even made a couple of friends.

    Today, I'm just an amateur violinist with a regular day job. As I sit in my community orchestra, sometimes I feel jealous(嫉妒的) my fellow musicians' instruments with their elegant voices. I may not be the best violinist around, but at least I'm still the loudest.

    It was very late and everyone had left the cafe except an old man who sat in the shadow the leaves of the tree made against the electric light. In the day time the street was dusty, but at night the dew settled the dust and the old man liked to sit late because he was deaf and now at night it was quiet and he felt the difference. The two waiters inside the cafe knew that the old man was a little drunk, and while he was a good client they knew that if he became too drunk he would leave without paying, so they kept watch on him.

     “Last week he tried to commit suicide,” one waiter said. “Why?” “He was in despair.” “What about?” “Nothing.” “How do you know it was nothing?” “He has plenty of money.”

    They sat together at a table that was close against the wall near the door of the cafe and looked at the terrace where the tables were all empty except where the old man sat in the shadow of the leaves of the tree that moved slightly in the wind. A girl and a soldier went by in the street. The street light shone on the brass number on his collar. The girl wore no head covering and hurried beside him.

     “The guard will pick him up,” one waiter said. “What does it matter if he gets what he's after?” “He had better get off the street now. The guard will get him. They went by five minutes ago.”

    The old man sitting in the shadow rapped on his saucer with his glass. The younger waiter went over to him.

     “What do you want?” The old man looked at him. “Another brandy,” he said.

     “You'll be drunk,” the waiter said. The old man looked at him. The waiter went away.

     “He'll stay all night,” he said to his colleague. “I'm sleepy now. I never get into bed before three o'clock. He should have killed himself last week.”

    The waiter took the brandy bottle and another saucer from the counter inside the cafe and marched out to the old man's table. He put down the saucer and poured the glass full of brandy.

     “You should have killed yourself last week,” he said to the deaf man. The old man motioned with his finger. “A little more,” he said. The waiter poured on into the glass so that the brandy slopped over and ran down the stem into the top saucer of the pile. “Thank you,” the old man said. The waiter took the bottle back inside the cafe.He sat down at the table with his colleague again.

     “He's drunk now,” he said. “He's drunk every night.” “What did he want to kill himself for?” “How should I know.” “How did he do it?” “He hung himself with a rope.” “Who cut him down?” “His niece.” “Why did they do it?” “Fear for his soul.” “How much money has he got?” “He's got plenty.” “He must be eighty years old.” “Anyway I should say he was eighty.” “I wish he would go home.I never get to bed before three o'clock. What kind of hour is that to go to bed?” “He stays up because he likes it.” “He's lonely. I'm not lonely. I have a wife waiting in bed for me.” “He had a wife once too.” “A wife would be no good to him now.” “You can't tell. He might be better with a wife.” “His niece looks after him.You said she cut him down.” “I know.” “I wouldn't want to be that old.An old man is a nasty thing.” “Not always.This old man is clean.He drinks without spilling.Even now, drunk.Look at him.” “I don't want to look at him.I wish he would go home.He has no regard for those who must work.”

    The old man looked from his glass across the square, then over at the waiters.

     “Another brandy,” he said, pointing to his glass.The waiter who was in a hurry came over.

     “Finished,” he said, speaking with that omission of syntax stupid people employ when talking to drunken people or foreigners. “No more tonight. Close now.”

     “Another,” said the old man.

     “No. Finished.” The waiter wiped the edge of the table with a towel and shook his head.

    The old man stood up, slowly counted the saucers, took a leather coin purse from his pocket and paid for the drinks, leaving half a peseta tip. The waiter watched him go down the street, a very old man walking unsteadily but with dignity.

     “Why didn't you let him stay and drink?” the unhurried waiter asked. They were putting up the shutters. “It is not half past two.” “I want to go home to bed.” “What is an hour?” “More to me than to him.” “An hour is the same.” “You talk like an old man yourself.He can buy a bottle and drink at home.” “It's not the same.” “No, it is not,” agreed the waiter with a wife. He did not wish to be unjust. He was only in a hurry. “And you? You have no fear of going home before your usual hour?” “Are you trying to insult me?” “No, hombre, only to make a joke.”

     “No,” the waiter who was in a hurry said, rising from pulling down the metal shutters.“I have confidence.I am all confidence.” “You have youth, confidence, and a job,” the older waiter said.“You have everything.” “And what do you lack?” “Everything but work.” “You have everything I have.” “No.I have never had confidence and I am not young.” “Come on. Stop talking nonsense and lock up.” “I am of those who like to stay late at the cafe,” the older waiter said.“With all those who do not want to go to bed.With all those who need a light for the night.” “I want to go home and into bed.” “We are of two different kinds,” the older waiter said.He was now dressed to go home.“It is not only a question of youth and confidence although those things are very beautiful. Each night I am reluctant to close up because there may be someone who needs the cafe.” “Hombre, there are bodegas open all night long.” “You do not understand.This is a clean and pleasant cafe.It is well lighted. The light is very good and also, now, there are shadows of the leaves.”

“Good night,” said the younger waiter.

     “Good night,” the other said. Turning off the electric light he continued the conversation with himself. It was the light of course but it is necessary that the place be clean and pleasant. You do not want music.Certainly you do not want music.Nor can you stand before a bar with dignity although that is all that is provided for these hours. What did he fear? It was not a fear or dread. It was a nothing that he knew too well. It was all a nothing and a man was a nothing too. It was only that and light was all it needed and a certain cleanness and order. Some lived in it and never felt it but he knew it all was nada y pues nada y nada y pues nada.

    He smiled and stood before a bar with a shining steam pressure coffee machine.

     “What's yours?” asked the barman.

     “Nada.” “Otro loco mas,” said the barman and turned away.

     “A little cup,” said the waiter.

    The barman poured it for him.

     “The light is very bright and pleasant but the bar is unpolished,” the waiter said.

    The barman looked at him but did not answer.It was too late at night for conversation.

     “You want another copita?” the barman asked.

     “No, thank you,” said the waiter and went out.He disliked bars and bodegas.A clean, well-lighted cafe was a very different thing.Now, without thinking further, he would go home to his room.He would lie in the bed and finally, with daylight, he would go to sleep.After all, he said to himself, it's probably only insomnia. Many must have it.

    Laziness is a state of inaction. It is something that you do, not something that you are. Being lazy means you have no motivation to do anything. Many people make the mistake that they view themselves as lazy.

    Lazy people are often seen as useless. They are the ones who don't do anything. They can be seen as underachievers or even bums（废物）. This can be a child or an adult. You can view a student who never studies as lazy. You can see an employee who doesn't do his work as lazy. In all of these cases, what the lazy person is doing is being lazy. But are they really being lazy or are they acting lazy?

    There is a huge different between saying you act lazy sometimes and you are a lazy person. One is suggesting that your laziness is temporary while the other suggests that it's permanent. This is the myth of laziness. People who are lazy aren't; they simply are people who are temporarily acting that way.

    So that causes a person to be inactive? The answer is a lack of goals. If you give someone a good enough reason to do something, they will do it. People who don't seem to do anything just haven't found a good enough reason to do something. Lazy students don't study because they don't see the point in studying. If you give them a reason, a strong enough reason, they will take action.

    For example, if you are too lazy to go to the gym, would you go if someone offered you a million dollars to go? If you are too lazy to go to clean out the garage, would someone pointing a gun to your head help you take action? The reason can be positive or negative as long as it's strong enough to induce（引起）action.

    To motivate someone who is lazy, what you need to do is to help them find purpose and enough reasons to work towards a certain goal.

    Rosa Parks became famous in 1955 when she refused to give up her seat on a bus to a white passenger in Montgomery, Alabama. She was important in the movement for civil rights（民权） in the American South during the 1950s and 60s. At the time, blacks in the South were forced to sit in the back of public buses and to give up their seats to white people.

    Parks moved to Detroit, Michigan, in 1957 to escape death threats. She continued living in Detroit until her death in 2005, at age 92. But the house in Detroit where Parks lived for many years was abandoned and scheduled to be torn down. Her niece, Rhea McCauley, bought it for $500 to stop it from being destroyed. She then gave it to American artist, Ryan Mendoza.

    Mendoza and others took it apart and then sent it across the Atlantic Ocean to the German capital of Berlin. There, he led efforts to rebuild the house. It now is behind his own house in Berlin. It gets daily visitors, although it is difficult to find, Mendoza said.

    But less than a year after the house was rebuilt in Berlin, Mendoza decided it should be returned to the United States. He made the decision after deadly violence took place at a recent white nationalist event in Charlottesville, Virginia. That incident increased calls for removing statues of Confederate（美国南部联邦的） leaders from the Civil War in the U.S.

    Mendoza said there are not enough civil rights monuments "to balance things out" with the Confederate statues. He said the Rosa Parks house belongs back in America "Imagine if the house were on a public setting in a prominent city in the U.S.," Mendoza said. "That's an education tool that shouldn't be denied by the American people. They have to know their past."

    The house would be welcomed back in Detroit. Detroit has failed to protect historical homes in the past. Such houses include the former home of Ralph Bunche, the first African-American to win the Nobel Peace Prize. Detroit's failure to protect history also is shown by the loss of the Rosa Parks house, Hammer said.

    The latest data from the Office for National Statistics shows that one in every 12 kids is living in homes where no one has worked for at least a year. That may be due to unemployment or issues such as sickness or disability that mean they can't work, and aren't required to. This is known as being in a "long term workless" family.

    The issues faced by children in workless families have very bad influence on their development and education, limiting their future employment prospects, and reducing their opportunities to succeed throughout their lives.

    Not only does worklessness reduce family income, it can also damage families' health and stability, and thus destroy children's development. This is because many workless families are held back by disadvantages such as debt, drug and alcohol dependency, and by homelessness. Suffering from the family problems, many children face a greater and greater possibility of repeating the poor outcomes of their parents. Government research has shown that children in workless families are almost twice as likely not to reach the expected level at all stages of their education. For example, three-quarters of children from families where no one works failed to reach the expected level at General Certificate of Secondary Education (GCSE), compared to around half of children in lower-income working families.

    So attention should be paid to children in out-of-work homes. Having working parents means a child is more likely to do better at school, to have better health, education and development, and also means they are less likely to fall into crime.

    But for some families, worklessness, or not employment, is the norm. They just choose not to work. These families often face huge barriers to getting on with their lives but they take the opportunities offered by the society. Parents' ability to work is frustrated by issues like low skills or poor mental or physical health, or drug and alcohol dependency, leaving children without the stability they need.

    We all want to help workless families with complex problems so that their children can take advantage of the opportunities in Britain. We all want parents to have the chance to go out to earn a living and to enjoy the pleasure of work, so that their children can benefit from the good examples of working parents. In doing so, we should know the need to understand the complex issues that some families face and to develop a new approach to deal with poverty. Because the root causes are not financial. It is about helping families overcome the problems they face so that they can go as far as their talents and hard work will take them. We shouldn't retreat from acting to deal with disadvantages, because we know the costs of inaction to individuals, communities and society.

Jack Horner is co-author of the book How to Build a Dinosaur. However, he is most famous for his role as consultant(顾问) on all four Jurassic Park films, including the new film Jurassic World.

The original film Jurassic Park tells the story of a theme park where dinosaurs live. In that movie, scientists used DNA collected by ancient mosquitoes that had been trapped in amber shortly after they drank dinosaur blood. The scientists used this dinosaur DNA to create baby dinosaurs. The scientists in Jurassic Park created various types of dinosaurs, but in the real world there is one big problem with the story. It turns out that DNA could not possibly survive the 65 million years since the death of the dinosaurs.

The new movie creates the Indominus Rex. This idea of creating a hybrid species is something Horner has explored before. In 2011, he gave a speech in which he discussed producing a dinosaur by working with the genes of a bird. Modern birds are the closest living relative of dinosaurs.

The concept of using the genes of different animals to create new animals is called transgenic science. And this type of science has already produced some interesting results — goats that produce spider silk in their milk, cows that produce proteins for medicines that can treat diseases, and a pig that produces less-polluting waste thanks to a bit of mouse DNA. However, none of these examples are close to the dinosaurs in Jurassic World. And for a good reason — genetics is a very complex science. Producing a new species is not as simple as just exchanging a few genes around.

In the end, Jurassic World is all about fun.
