    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

    Everyone looks forward to progress, whether in one's personal life or in the general society. Progress indicates a person's ability to change the way he is living at the moment. Progress must lead a better way of doing things. All these, however, remains true only in so far as people want to accept technology and move forward by finding new and more efficient ways of doing things.

    However, at the back of the minds of many people, especially those who missed the “good old days”, efficiency comes with a price. When communication becomes efficient, people are able to contact one another no matter where they are and at whatever time they wish to. The click of a button allows people miles apart to talk or to see each other without even leaving their homes. With the communication gadgets, such as mobile phones and ipads, people often do not take the effect to visit one another personally. A personal visit carries with it the additional feature of having to be in the person's presence for as long as the visit lasts. We cannot unnecessarily excuse our selves or turn the other person off.

    With efficiency also comes mass production. Such is the nature of factories and the success of industrialization today. Factories have improved efficiency. Unskillful tasks are left to machines and products are better made and produced with greater accuracy than any human hand could ever have done. However, with the improvements in efficiency also comes the loss of the personal touch when making these products. For example, many handcrafts(手工艺品) are now produced in a factory. Although this means that supply is better able to increase demand, now that the supply is quick and efficient, the demand might fall because mass production lowers the quality of the handicraft and it is difficult to find unique designs on each item.

    Nevertheless, we must not commit the mistake of analyzing progress only from one point of view. In fact, progress has allowed tradition to keep up. It is only with progress and the invention of new technology that many old products can be brought back to their old state. New technology is required for old products to stay old.

    It is people's attitude towards progress that causes the type of influence that technology has on society. Technology is flexible. There is no fixed way of making use of it. Everything depends on people's attitude. The worst effects of progress will fall on those who are unable to rethink their attitudes and views of society. When we accept progress and adapt it to suit our needs, a new “past” is created.

    A heated debate is currently going on in our town.Should we allow the cinema to be constructed in the Havenswood Shopping Center? There is just one large lot left to build on,and the theater would use up all of that space.Some people are excited at the idea of finally having our own movie theater.Others would rather travel ten miles to the nearest theater to keep our quiet town the way it is.They say it is enough to have Marvin's Movie Video Rentals.After all,Marvin's store keeps thousands of the latest videos.

    There are certainly benefits to renting videos.For one thing,you can plan your own schedule when it is convenient for you.You can relax on your sofa,and take a break whenever you need one.You can also talk to others without bothering any strangers seated nearby.In additional,it is a less expensive way to view a movie compared to going to a theater.

    On the other hand,seeing a movie in a theater is an experience all its own.First,you can see the movie on wide screen as the filmmaker intended.To be viewed on a television screen,a film must be changed in some way to make it smaller.One is the “pan-and-scan” method,which involves removing some of the details in the picture.The other way,called “letterboxing”,keeps the image the way it is on the big screen,with one annoying exception; because the big-screen version is wide,the same picture on a television screen must be long and narrow.

    Another problem is sound.The sound from a television cannot compare to the sound system in a theater.Your experience of a movie improves when you can clearly hear all of the sounds.Furthermore,at home,viewing companions often talk during a movie,which makes you miss out on what's happening in the film.

    Besides,having a movie theater will not mean that you can't still go to Marvin's! You will just have a choice that you didn't have before.Isn't it time for Havenswood residents to enjoy a little progress?

    A day in the life of 18-year-old David Lanster is full if typical teenage stuff: school, baseball practice and homework. And then he starts cooking. “Some nights I'm up until 1:00 a.m. making pies, or even later if we're cooking beef,” said the student at Ransom Everglades High School in Florida, US.

    For the past year, Lanster and Kelly Moran, his classmate, have been hosting fancy dinner parties at Lanster's parents' home. Their meals have 17 courses and are all made by them. Their guests used to give them gifts to thank them until the pair decided to do something nice for charity(慈善). “We got some really great Miami Heat tickets, a nice watch, and many kitchen gadgets(小器具),” Lanster said. “But we wanted to make this something positive for people other than us.”

    Lanster and Moran focused on Common Threads, a charity that aims to teach kids in poor communities to cook and make healthy eating choices. The young cooks ask their guests to give however much they want as payment for their meals. It all goes to Common Threads because Lanster's parents cover their food costs. After their last 12-person event, Lanster and Moran gave $1,600 to the charity.

    Now, they're taking their show out of the kitchen and on the road. They have started to organize private dinner parties with a similar model: the host pays for the ingredients, and the guests make a donation to a charity of their choice.

    Without formal training, Lanster said he had been interested in cooking since he helped his mom in the kitchen when he was very young. He learned how to cook by reading cookbooks and watching TV programs. Outside the kitchen, the two are busy preparing their college applications. Neither of them is sure what they will do in the future, but they're promised their parents that they will leave professional cooking alone until they finish school.

    After finishing a meal at an American Chinese restaurant you probably expect to receive a handful of fortune cookies after you pay the bill. Fortune cookies are in Chinese restaurants throughout the United States. It's rather satisfying to crack open a cookie at the end of your meal and read your “lucky fortune” on the slip of paper inside.

    The exact origin of the fortune cookie is unknown. It is thought that the tasty snack was the first introduced into San Francisco in 1914, after an immigrant began distributing the cookie with “thank you” notes in them. These “thank you” notes were intended as symbols of appreciation for friends who stood with him through the economic hardship and discrimination of his early life in America.

    There is an alternate origin story. Los Angeles is regarded as the site of the fortune cookie's invention. In this version of the story, David Jung, a Chinese immigrant residing in L. A., is thought to have created the cookie in order to uplift the spirits of the poor and homeless. In 1918, Jung handed out the cookies for free to the poor outside his shop and each cookie contained a strip of paper with an inspirational sentence printed on it.

    Fortune cookies first began to gain popularity in mainstream American culture during WWII. Chinese restaurants would serve them in place of desserts, as desserts were not popular in traditional Chinese cuisine. Today fortune cookies are not tied to Chinese-American culture. In fact, the largest fortune cookie manufacturer is located in the United States and it produces 4.5 million fortune cookies a day —— an evidence to the modern-day popularity of the snack. However, an attempt to introduce the fortune cookie to China in 1992 was a failure, and the cookie was cited for being “too American.”

    So the next time you break open a fortune cookie and read a fortune about the many successes you should expect in your future, remember that the conclusion to your Chinese restaurant meal may not be as Chinese as you think.

    Growing up, I was an extremely reserved(腼腆的) boy. I didn't have many friends in primary and middle school and rarely opened up to anyone. I didn't even ask my teacher questions in class. I was scared of the world and the people around.

    As a child, I was scared to do anything without my parents mainly because I was afraid that I would do it badly. I was getting good grades and was well-behaved, but I wasn't happy. It was my belief that I was, for some reason, unable to do the things the others kids could do. I felt inadequate.

    While in my second semester of college, I ran into some information on the Internet about something called social anxiety. I didn't really know much of the disorder. Thus I began to read about some of the symptoms and realized that social anxiety was the thing that hurt me so much.

    It is common knowledge that people with social anxiety experience nervousness in social situations. What a lot of people don't know is that one of the main causes of social anxiety is negative thinking. People having a negative idea of themselves often think that they are ugly or stupid.

    I realized what I was truly afraid of: not being good enough. I was afraid that people would look at me and would not like what they saw; I was scared of rejection. To help deal with these problems, I began to practice meditation(沉思) and other mindfulness exercises. My mind slowly began to change.

    I realized that everyone, from star athletes to noble prize winners, experiences fear in their lives. Whether people are afraid of heights, planes, spiders, or talking to girls, we all experience anxiety and fear. There is no reason for anyone to feel excluded(排除在外的) because something scares them. People with anxiety disorders might have "problems", but there is nothing wrong with them as people. They are just as humans as everyone else.
