    Experiments under way in several labs aim to create beneficial types of genetically modified foods, including starchier potatoes and caffeine-free coffee beans. Genetic engineers are even trying to transfer genes from a cold-winter fish to make a frost-resistant tomato.

    A low-sugar GM strawberry now in the works might one day allow people with health problems such as diabetes (糖尿病) to enjoy the little delicious red fruits again. GM beans and grains rich in protein(蛋白质) might help people at risk of developing kwashiorkor. Kwashiorkor, a disease caused by severe lack of protein, is common in parts of the world where there are severe food shortages.

    Commenting on GM foods, Jonathon Jones, a British researcher, said: "The future benefits will be enormous(巨大的), and the best is yet to come". To some people, GM foods are no different from unmodified foods. "A tomato is a tomato," said Brian Sansoni, an American food manufacturer.

    Critics of GM foods challenge Sansoni's opinion. They worry about the harm that GM crops might do to people, other animals, and plants.

    In a recent lab study conducted at Cornell University, scientists tested pollen(花粉) made by BT corn, which makes up one-fourth of the U.S. corn crop. The scientist dropped the pollen onto milkweed, a plant that is the only known food source of a butterfly caterpillar(毛虫). Within four days of feeding on the leaves, almost half of a test group of caterpillars died. "This is a warning bell." said Cornell researcher Linda Raynor.

    Some insects that are not killed by GM foods might find themselves made stronger. How so? The insecticides are used on the crops to kill the pests. But GM plants produce a continuous level of insecticide. Insects relying on those crops may develop resistance to the plants and they may also develop a resistance to the insecticide.

    At the forum on GM food held last year in Canada. GM crops that have been made resistant to the herbicide might crossbreed with wild plants, creating "superweeds" that could take over whole fields.

    So where do you stand? Should GM food be banned in the United States, as they are in parts of Europe? Or do their benefits outweigh(胜过) any of the risks they might carry?

(1)、The first three paragraphs try to give the idea that__________
A、GM foods may bring about great benefits to humans. B、GM foods are no different from ordinary ones. C、GM foods may have both benefits and harm. D、GM foods are particularly good to the kwashiorkor patients.
(2)、Why is the pollen-sprayed milkweed mentioned in Paragraph 5?
A、To show GM foods can kill insects effectively. B、To show GM foods contain more protein. C、To show GM foods also have a dark side. D、To show GM foods may harm crops.
(3)、What happens to those insects when not killed by the spray of insecticide?
A、They may lose their ability to produce lay eggs. B、They may have a higher ability to adapt to the environment. C、They move to other fields free from insecticide. D、They never eat again those plants containing insecticide.
(4)、Which of the following statements concerning banning GM foods is true according to the passage?
A、Underdeveloped countries have banned GM foods. B、Both Europe and the U.S. have banned GM foods. C、Most European countries have not banned GM foods. D、The United States has not banned GM foods.

    A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility (能见度) of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.

    The study was led by Prof Ho. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analysed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6. 1 fewer accidents per 1,000 taxis per month.

    They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio (比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76. 6 fewer accidents will occur per month or 917 fewer accidents per year.

    Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $2 million.

    “We are eager to continue to validate (证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we' re also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors explained Prof Ho.

    In 1880, fourteen-year-old Matthew Henson loved to hear sailors tell tales of their exciting lives at sea. The travel, the adventure, the danger, and the steady pay were all attracting young Henson. One day, he found a job as a cabin boy on a beautiful ship called the Katie Hinds. For the next five years, Henson sailed around the world. With the help of the ship's captain and other members of the crew, Henson learned mathematics, navigation, history, geography, and many other subjects. By the time he left the Katie Hinds in 1885, Henson was well educated and had become an excellent seaman.

    Unable to find work anywhere else, Henson took a job in a hat shop in Washington, D.C. One day in 1887, a man came in to buy a hat. The man, Robert Peary, asked the owner if he knew anyone with experience at sea. Peary would soon travel to South America for the U.S. government. He needed experienced men to accompany him. The shop owner knew about his young employee's skills and experience on ocean journeys, so he introduced Peary to Henson.

    Using his map-reading and sailing skills, Henson proved himself to be a worthy and smart seaman. Peary soon made Henson his assistant(助理), and they became close friends. One day Peary told Henson about his real dream: to be the first man to stand on “the top of the world” at the North Pole. He asked Henson to help him make his dream come true. Over the next five years, the two explorers made two trips together to the Arctic. However, they were not able to reach the pole either time. The cold, wind, and ice were worse than either of them had ever imagined.

    In 1908, Peary and Henson were ready to make their final attempt at reaching the North Pole. Both men were over forty years old. The years of hardship in the arctic cold had made them suffer a lot. This would be their last chance. With four Inuit(因纽特)guides, they made a mad rush straight across the ice toward the pole. Peary's feet were injured and he had to be pulled on a dogsled. In April 1909, Henson's instruments showed they were standing at the North Pole. Together Henson and Peary planted the American flag in the snow.

    In later years, Robert Peary and Henson were greatly honored for their achievements. Today, the two friends and fellow explorers lie in heroes' graves not far apart in the Arlington National Cemetery.

    Now many young people are traveling around the world on their own, not because they have no one to travel with, but because they prefer to go alone.

    Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life, “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.

    In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen, it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.

    Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website, The Aussie Nomad, to document his adventures. He says he wished he had traveled alone earlier. “The people you meet, the places you visit, or the things you do, everything is up to you and it forces you to grow as a person,” said the 30-year-old man.

    Richardson describes traveling alone like “a shot in the arm”, which “makes you a more confident person that is ready to deal with anything”. He said, “The feeling of having overcome something on my own is a major part of what drives me each day when I'm dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”

    The great 19th century explorer John Muir once said, “Only by going alone in silence can one truly get into the heart of the wilderness.”

    I grew up in a house where the TV was seldom turned on and with one wall in my bedroom entirely lined with bookshelves,most of my childhood was spent on books I could get hold of. In fact,I grew up thinking of reading as natural as breathing and books unbelievably powerful in shaping perspectives (观点) by creating worlds we could step into,take part in and live in.

    With this unshakable belief,I,at fourteen,decided to become a writer. Here too,reading became useful. Every writer starts off knowing that he has something to say,but being unable to find the right ways to say it. He has to find his own voice by reading widely and discovering which parts of the writers he agrees or disagrees with,or agrees with so strongly that it reshapes his own world. He cannot write without loving to read,because only through reading other people's writing can one discover what works,what doesn't and, in the end,together with lots of practice,what voice he has.

    Now I am in college,and have come to realize how important it is to read fiction (文学作品).As a law student,my reading is in fact limited to subject matter — the volume (量) of what I have to read for classes every week means there is little time to read anything else. Such reading made it all the clearer to me that I live in a very small part in this great place called life. Reading fiction reminds me that there is life beyond my own. It allows me to travel across the high seas and along the Silk Road,all from the comfort of my own armchair,to experience,though secondhand,exciting experiences that I wouldn't necessarily be able to have in my lifetime.

    Both honeybees and ants are social insects that live in groups called colonies. They survive by means of their collective intelligence. Their decision-making power is distributed throughout the group; that is, no one ant or bee makes decisions for the group. Instead, they work together. As Deborah M. Gordon, a biologist at Stanford University, says," Ants aren't smart. Ant colonies are."

    The same is true for bee colonies. Although bees and ants are quite different physically, they have a lot in common in terms of their social behavior. Specifically, honeybees and ants have similar roles within the colony, both have communication systems, and both have the capacity for learning.

    Ants communicate by using chemicals called pheromones, which can alert others to danger or to a food source. For example, when worker ants find a promising source, they let the rest of the colony know how to find it by leaving a trail of pheromones on the way back to the colony. The other ants pick up the message using their sense of smell. Bees, on the other hand, use movement to communicate with each other. Worker bees send messages to each other by means of a "dance". Different speeds and movements send different messages. For example, when worker bees called scouts go out to find a new home for the colony, they return and do a dance for the other worker bees that indicates the location of the new home and how suitable it is. The faster the scouts dance, the better the new location is.

    Honeybees and ants are both capable of learning. One Chinese study found that bees can be trained to learn and remember a route to a food source. The researchers also found that bees can be taught to recognize hidden objects and use the concepts of "sameness" and" difference" to accomplish certain tasks. Ants take this one step further. Recent American research has shown that ants not only have the ability to learn, but also can teach their foraging skills to other younger ants.

They observed that older ants accompany young ants in search of food and teach them the route and how to avoid obstacles.

    As we can see, the social behavior of honeybees and ants is quite similar. Both coordinate complex actions and accomplish crucial survival tasks by cooperating in groups consisting of many individuals. Unintelligent as they may be as individuals, as groups they often show amazing brilliance as they go about their everyday activities.
