If your recurring (经常性的) dreams are worryingyou,you can rest assured and needn"t worry. Psychologists say in the vast majority of these cases,this is just the mind"s way of dealing with stress and conflicts,problems and concerns.It"s a good thing. They call be surprisingly vivid and real,or fragmented and weird.They can be comforting or frightening. Our dreams can tell us a lot about what we are really thinking.Dreams give us an x-ray of our unconsciousness(潜意识).They tell us,particularly when we are at life"s passages or turning points. Lisa Oppenheim had the same dream whenever she was about to move to a new home or a new city. It"s always just a feeling of needing to stay safe.Experts say disturbing dreams often occur around major life events.For Lisa,it was moving.For others,it can be marriage or divorce,the death of a loved one or pressure at work. Doctor Siegel has studied the meaning of dream for nearly 30 years.He believes stressful or upsetting dreams can be a sign of what"s buried deep inside our minds. He said."Dreams are important to survival.They are crucial to the balance of our psyche(心灵).They help us work out problems that we"re having every single day.They go to the cutting edge of what"s stressful,what"s bothering us and what we"re working out in our lives.Dreams can guide us and in order to find that guidance,to find that deep source of wisdom that"s in our dreams every night,we need to pay attention to our dreams." But many dreams are scary and horrible.How can we understand these nightmares? Doctor Siegel says they are reflecting especially intense emotion or unresolved conflict.The stronger the emotion in the dream,whether it"s pleasure or fear,the likelier the dream is to be important. Knowing what your recurring dreams or nightmares mean can be liberating.Some nightmares can be a sign of serious psychological problems,such as post-dramatic stress disorder.If they are extremely disturbing or violent or the cause of severe anxiety,you should see a professional therapist (治疗专家). |

Knowing the best way to study will help you to be a better student. By using your time properly, you can do your homework more quickly. Learning to study is not difficult. The first thing to remember is that you must be willing to learn. It doesn"t mean that you must always like the subject. It does mean, however, that you must be willing to do whatever is necessary to learn. Try to understand why it is important and how it will help you now and later to do and learn other things. Knowing mathematics facts will be useful in your whole life. Knowing how to spell makes any kind of writing easier. Sometimes the subject that you think is going to be uninteresting will be exciting when you begin to work at it and understand it more clearly. Learning things can be fun if you are willing to work with them. Here"s some advice for you: have a certain time each day and a quiet place with good lighting for study, so that you can concentrate on your study without interruptions; have everything ready before you sit down to study, a dictionary, paper, a pen and books; be sure you understand what you should learn before you start; read carefully and pay special attention to the most important things; when memorizing, first find out the main parts and then recite the whole thing; check your homework after you finish it; never forget the importance of review and preview. Don"t try to spend a lot of time researching learning methods. There are many students who know many good learning methods but don"t study well. They forget that the most useful learning method is to study hard. |

Harvard researchers have created a tough, low-cost, biodegradable (可生物降解的) material inspired by insects" hard outer shells. The material"s inventors say it has a number of possible uses and someday could provide a more environmentally friendly alternative to plastic. The material, made from shrimp (虾) shells and proteins produced from silk, is called "shrilk." It is thin, clear, flexible and strong. A major benefit of the material is its biodegradability. Plastic"s toughness and flexibility represented a revolution in materials science during the 1950s and "60s. Decades later, however, plastic"s very durability (耐用性) is raising questions about how appropriate it is for one-time products such as plastic bags, or short-lived consumer goods, used in the home for a few years and then cast into a landfill where they will degrade for centuries. What is the point of making something that lasts 1,000 years? Shrilk not only will degrade in a landfill, but its basic components are used as fertilizer (肥料), and so will enrich the soil. Shrilk has great potential, the inventors said. Materials from which it is made are plentiful in nature, found in everything ranging from shrimp shells, insect bodies to living plants. That makes shrilk low cost, and its mass production possible should it be used for products demanding a lot of material. Work on shrilk is continuing in the lab. The inventors said the material becomes flexible when wet, so they"re exploring ways to use it in wet environments. They"re also developing simpler production processes, which could be used for non-medical products, like for computer cases and other products inside the home. They"re even exploring combining it with other materials, like carbon fibers, to give it new properties. |
1. Paragraph 1 of the passage is mainly about shrilk"s _________. |
A. remarkable design B. interesting name C. major features D. basic elements |
2. What has become a concern about plastic? |
A. Using it properly. B. Producing it cheaply. C. Developing its properties quickly. D. Evaluating its contributions fairly. |
3. According to the inventors, shrilk has great potential partly because _________. |
A. it can help plastic degrade B. it can be found in living things C. its mass production has been realized D. its raw materials are abundant in nature |
4. What are the inventors doing in the lab? |
A. Replacing carbon fibers with shrilk. B. Testing shrilk"s use in wet conditions. C. Making shrilk out of used household goods. D. Improving shrilk"s flexibility for medical purposes. |
5. Which of the following can be the best title for the passage? |
A. Recent Progress in Environmental Protection B. Benefits of Insects in Scientific Research C. The Harm of One-time Products D. A Possible Alternative to Plastic |

Deputy Agriculture Secretary Kathleen Merrigan sees an epidemic (流行病) sweeping across America"s farmland. It has little to do with the usual challenges, such as flood, rising fuel prices and crop-eating insects. The country"s farmers are getting older, and there are fewer people standing in line to take their place. National agricultural census (普查) figures show that the fastest-growing group of farmers is the part over 65. Merrigan is afraid the average age will be even higher when the 2012 statistics are completed. Merrigan, a former college professor, is making stops at universities across the country in hopes of encouraging more students to think about careers in agriculture. Aside from trying to stop the graying of America"s farmers, her work is made tougher by a recent blog posting that put agriculture at No. 1 on a list of "useless" college degrees. Top federal agriculture officials are talking about the posting, and it has the attention of agricultural organizations across the country. "There couldn"t be anything that"s more incorrect," Merrigan said. "We know that there aren"t enough qualified graduates to fill the jobs that are out there in American agriculture." In addition, a growing world population that some experts predict will require 70% more food production by 2050, she said. "I truly believe we"re at a golden age of agriculture. Global demand is at an all-time record high, and global supplies are at all-time record lows," said Matt Rush, director of the Texas Farm Bureau. "Production costs are going to be valuable enough that younger people are going to have the opportunity to be involved in agriculture." The Department of Agriculture has programs aimed at developing more farmers and at increasing interest in locally grown food. The National Young Farmers" Coalition has also been pushing for state and federal policy changes to make it easier for new farmers. Ryan Best, president of Future Farmers of America, has been living out of a suitcase, traveling the country and visiting with high school students about careers in agriculture. The 21-year-old Best hopes his message-that this is a new time in agriculture-will motivate the next generation to turn around the statistics. "Never before have we had the innovations (创新) in technology which have led to agriculture in this country being the most efficient it has ever been," he said. "There"s really a place for everybody to fit in." |
1. What is the new challenge to American agriculture? |
A. Fewer and older farmers. B. Higher fuel prices. C. More natural disasters. D. Lower agricultural output. |
2. Why is Merrigan visiting universities across the country? |
A. To draw federal agriculture officials" attention. B. To select qualified agriculture graduates. C. To clarify a recent blog posting. D. To talk more students into farming careers. |
3. According to Matt Rush, American agriculture will provide opportunities for younger people because__________.. |
A. the government will cover production costs B. global food supplies will be even lower C. investment in agriculture will be profitable D. America will increase its food export |
4. What do the underlined words "to turn around the statistics" in the last paragraph mean? |
A. To re-analyze the result of the national census. B. To increase agricultural production. C. To bring down the average age of farmers. D. To invest more in agriculture. |

Medical drugs sometimes cause more damage than they cure. One solution to this problem is to put the drugs inside a capsule, protecting them from the body-and the body from them-until they can be released at just the right spot. There are lots of ways to trigger (引发) this release, including changing temperature, acidity, and so on. But triggers can come with their own risks-burns, for example. Now, researchers in California have designed what could be a harmless trigger to date: shining near-infrared light (NIR, 近红外线) on the drug in the capsule. The idea of using light to liberate the drug in the capsule isn"t new. Researchers around the globe have developed polymers (聚合物) and other materials that begin to break down when they absorb either ultraviolet (UV, 紫外线) or visible light. But tissues also readily absorb UV and visible light, which means the drug release can be triggered only near the skin, where the light can reach the capsule. NIR light largely passes through tissues, so researchers have tried to use it as a trigger. But few compounds (化合物) absorb NIR well and go through chemical changes. That changed last year when Adah Almutairi, a chemist at the University of California, San Diego, reported that she and her colleagues had designed a polymer that breaks down when it absorbs NIR light. Their polymer used a commercially available NIR-absorbing group called o-nitrobenzyl (ONB). When they catch the light, ONB groups fall off the polymer, leading to its breakdown. But ONB is only a so-so NIR absorber, and it could be poisonous to cells when it separates from the polymer. So Almutairi and her colleagues reported creating a new material for capsules that"s even better.This one consists of a long chain of compounds called cresol groups linked in a polymer. Cresol contains reactive(易反应的) components that make it highly unstable in its polymeric form, a feature Almutairi and her colleagues use to their advantage. After polymerizing the cresols, they cap each reactive component with a light-absorbing compound called Bhc. When the Bhcs absorb NIR light, the reactive groups are exposed and break the long polymer into two short chains. Shining additional light continues this breakdown, potentially releasing any drugs in the capsule. What"s more, Almutairi says, Bhc is 10 times better at absorbing NIR than is ONB and is not poisonous to cells. |
1. According to the passage, which of the following could be the best trigger? |
A. Temperature change. B. NIR light. C. Acidity change. D. UV light. |
2. Why is ONB unsatisfactory? |
A. It breaks down when it absorbs NIR light. B. It falls off the polymer and triggers drug release. C. It has not come onto the market up till now. D. It is not effective enough and could be poisonous. |
3. Which word can be used to complete the following process of changes? |
A. protected B. formed C. exposed D. combined |
