    Scientists are debating how to limit their newly-discovered power to change genetic structure (结构). Scientists already modify the genes (基因) of farm animals and agricultural plants to make them more productive or stronger. But now they can also change genes in wild animals and plants. These genes would continue into later generations. For example, it may be possible for scientists to remove from existence the kind of mosquitoes, small flying insects, that carry the Zika virus. They might also be able to permanently remove species (物种) of plants and animals that are damaging to other species.

    In a report published last week, the U. S. National Academies of Sciences, Engineering and Medicine (NAS) said it supports continued research on this kind of gene control. But it warned that it is not possible to know what will happen when these changed plants and animals are released (释放) into the wild.

    Sixteen biologists, ethicists (伦理学家) and policymakers are on an NAS committee that is examining the issue. They say that there is value to the new technology. But, they say, there is not enough evidence to support the release of modified organisms (生物体) from the laboratory into nature.

    Many people would support stopping mosquitoes and rats from carrying diseases. But scientists say we must understand the possible scientific, ethical, legal and social results of such action before we decide whether to take it. Gene modification is spread through reproduction (繁殖).

    Changed genes will continue to spread as long as an animal or plant continues to reproduce. They cannot be limited to a farm or kept within a country's borders. Scientists are wondering what may happen if a modified organism mates with another species. They are not yet sure how the modified genes would affect the other species. It is possible that those genes could harm those creatures or even lead to their disappearance from our planet.

(1)、What possible advantage does gene control in wild animals and plants have?

A、Changing the Zika virus permanently. B、Getting rid of damaging species forever. C、Having the changed genes in their next generations. D、Making all the species more productive and stronger.
(2)、As for genetically changed wild animals and plants, what are scientists worried about?

A、They may become weaker or die out. B、They may be more productive than before. C、They may cause damage to their living habitat. D、Their genes may spread to later generations.
(3)、Which of the following is true according to the passage?

A、Scientists are certain what exact results gene modification leads to. B、Gene modification can benefit some farm animals and agricultural plants. C、Scientists won't modify any genes before they make the final decision. D、Gene modification will be encouraged in more creatures in the near future.
(4)、The article is mainly intended to ________.

A、appeal against research on gene control B、show how to change genetic structure C、inform us of power and danger of gene control D、give the reason why gene modification is necessary

    From the very beginning of school we make books and reading a constant source of possible failure and public humiliation. When children are little we make them read aloud, before the teacher and other children, so that we can be sure they “know” all the words they are reading. This means that when they don't know a word, they are going to make a mistake, right in front of everyone. After having taught fifth-grade classes for four years, I decided to try at all costs to rid them of their fear and dislike of books, and to get them to read oftener and more adventurously.

    One day soon after school had started, I said to them, “Now I'm going to say something about reading that you have probably never heard a teacher say before. I would like you to read a lot of  books this year, but I want you to read them only for pleasure. I am not going to ask you questions to find out whether you understand the books or not. If you understand enough of a book to enjoy it and want to go on reading it, that's enough for me. Also I'm not going to ask you what words mean. “

    The children sat stunned and silent. Was this a teacher talking? One girl, who had just come to us from a school where she had had a very hard time, looked at me steadily for a long time after I had finished. Then, still looking at me, she said slowly and seriously, Mr Holt, do you really mean that?” I said just as seriously, “I mean every word of it.

    During the spring she really astonished me. One day, she was reading at her desk, From a glimpse of the illustrations I thought I knew what the book was. I said to myself, “It can't be,” and went to take a closer look. Sure enough, she was reading Moby Dick , in edition with woodcuts. I said, “Don't you find parts of it rather heavy going?” She answered, Oh, sure, but I just skip over those parts and go on to the next good part. “

    This is exactly what reading should be and in school so seldom is, an exciting, joyous adventure. Find something, dive into it, take the good parts, skip the bad parts, get what you can out of it, go on to something else. How different is our mean-spirited, picky insistence that every child get every last little scrap of “understanding” that can be dug out of a book.

    The word advertising refers to any kind of public announcement that brings products and services to the attention of people. Throughout history, advertising has been an effective way to promote(促进)the trading and selling of goods. In the Middle Ages, merchants employed "town criers" to read public messages aloud to promote their goods. When printing was invented in the fifteenth century, pages of advertisements(ads)could be printed easily and were either hung in public places or put in books.

    By the end of the seventeenth century, when newspapers were beginning to be read by more people, printed materials became an important way to promote products and services. The London Gazette was the first newspaper to set aside a place just for advertising. This was so successful that by the end of the century several companies started businesses for the purpose of making newspaper ads for merchants.

    Advertising spread quickly throughout the eighteenth century. Ad writers were starting to pay more attention to the design of the ad text. Everything, from clothes to drinks, was promoted with clever methods such as repetition of the firm's name or product, words organized in eyecatching patterns, the use of pretty pictures and expressions easy to remember.

    Near the end of the nineteenth century, companies that were devoted to the production of ads came to be known as "advertising agencies(广告商)."The agencies developed new ways to get people to think of themselves as members of a group. Throughout the twentieth century, advertising agencies promoted consumerism(消费主义)as a way of life, spreading the belief that people could be happy only if they bought the "right" products.

    One night, Pilar was in a deep sleep when she was woken by her cat Inti. Inti was meowing wildly outside Pilar's bedroom and throwing himself against the closed bedroom door. When Pilar opened her eyes, she saw that her bedroom was filled with smoke. As she escaped her house with Inti in her arms, she saw that a fire was burning in her kitchen. Pilar could easily have lost her life, but Inti would not let that happen. Even though Inti could have escaped the house through a cat door, he wouldn't leave Pilar.

    As amazing as this story is, it is not as uncommon as you may think. Take the example of Charlotte Lee and her horse, Thunder. One summer night, the whole family was asleep with the windows open. It was normally very quiet where they lived. Suddenly, there was a loud noise. Charlotte woke up from her sweet dream, and the noise continued. Then she heard a horse running fast towards the house. The next thing she saw was Thunder standing outside her window, neighing(嘶叫) and shaking his head. She knew something was wrong. Charlotte quickly got everyone out of the house before the earthquake hit. Thunder has saved her life.

    There are also stories of wild animals coming to the rescue of humans. One animal known to be a friend of humans is the dolphin. Once, Todd Endris was surfing with his friends when he was attacked by a 13-foot(4-meter) shark. In the middle of the attack, a group of dolphins came to his rescue by forming a protective ring around Endris until he could get safely to shore. Without the help of the dolphins, there is little chance that Todd could have escaped.

    No one is sure why animals have so often come to our rescue. However, it is clear that humans and animals enjoy a close relationship. It is important that we care for them as much as we can.

    No one enjoys hearing the sound of someone else chewing their food. Most of the time, though, it's not that big a deal but a minor annoyance.

    But for a small group of people with misophonia (恐音症), the sound can be painful, causing extreme anger and deep discomfort. The most ordinary sounds of chewing and breathing can drive them crazy. Past attempts to explain the causes of misophonia have suggested everything from compulsive disorder to an easily-annoyed personality—but according to a study published yesterday in the journal CurrentBiology, the true criminal is the structure of the brain.

    For the study, a team of researchers led by Newcastle University neuroscientist Sukhbinder Kumar recruited (招募) 42 volunteers, of whom around half had extreme misophonia and the other half served as the control group, and played them several different noises: some ordinary; some harsh, like the sound of a person screaming; and some that were ordinary for the control group but known to be annoying for misophonics, people with misophonia, like the sound of breathing. As the participants listened, the researchers monitored them for signs of anxiety, both physical symptoms and behavioral expressions, and observed their brain activity using FMRI scans.

    The only significant difference in reaction between the two groups happened, during the misophonia-specific sounds, when those with the condition showed physical changes that suggested they were entering fight-or-flight mode.

    Misophonics had increased activity in the AIC, an area known to play a central role in the system that determines which things we should pay attention to. When the trigger sounds were played, there was not only more activity in this region but also abnormally high levels of connection to other regions.

    Misophonia, in other words, may be a result of misplaced attention the brain of a misophonic focuses on things that other people normally tune out (不予理会). On a related note, on behalf of misophonics and manners-minded moms everywhere: Please, chew with your mouth closed.

    One time a young man, who hoped to study law, wrote to Lincoln for advice, and Lincoln replied, "If you are determined to make a lawyer of yourself, the thing is more than half done already. Always bear in mind that your own determination to succeed is more important than any other one thing."

    Lincoln knew. He had gone through it all. He had never, in his entire life, had more than a total of one year's schooling. And books?Lincoln once said he had walked to borrow every book with in fifty miles of his home. A fire was usually kept going all night in the small house and he read by the light of it.

    He walked twenty or thirty miles to hear a speaker and, returning home, he practiced his talks everywhere﹣in the fields, in the woods, before the crowds. He joined several societies and practiced speaking on the topics of the day.

    A lack of confidence always troubled him. In the presence of women he was shy and dumb. Even when he was in love with Mary Todd, he used to sit there, nervous and silent, unable to find words, listening while she did the talking. Yet that was the man who, by practice and home study, made himself into the speaker who debated with the famous speaker Douglas! That was the man who, in Gettysburg address, rose to the heights of eloquence (雄辩) that have seldom been achieved in all the human history.

    Small wonder that, speaking of his own great barriers and painful struggle, he wrote, "If you are determined to make a lawyer of yourself, the thing is more than half done already."
