单选题In face of global warming, much effort has been focused on reducing greenhouse gas emissions through a variety of strategies. But while much of the research and innovation has 26 on finding less-polluting energy alternatives, it may be decades before clean technologies like wind and solar meet a significant portion of our energy needs. In the meantime, the amount of CO2 in the air is rapidly 27 the limits proposed by the Intergovernmental Panel on Climate Change (IPCC). 'As long as we're consuming fossil fuels, we're putting out CO2, ' says Klaus Lackner, a geophysicist at Columbia University. 'We cannot let the CO2 in the atmosphere rise 28 . ' That sense of urgency has increased interest in capturing and storing CO2. which the IPCC says could provide the more than 50% reduction in emissions thought needed to reduce global warming. 'We see the 29 for capture and storage to play an integral role in reducing emissions, ' says Kim Corley, Shell's senior advisor of CO2 and environmental affairs. That 30 thinking strategy is gaining support. The U. S. Department of Energy recently proposed putting $1 billion into a new $2.4 billion coal-burning energy plant. The plant's carbon-capture technologies would serve as a 31 project for other new coal-burning plants. But what do you do with the gas once you've captured it? One option is to put it to new uses. Dakota Gasification of North Dakota captures CO2 at a plant that 32 coal into synthetic natural gas. It then ships the gas 200 miles by pipeline to Canada, where it is pumped underground in oil recovery operations. In the Netherlands, Shell delivers CO2 to farmers who pipe it into their greenhouses, increasing their 33 of fruits and vegetables. However, scientists say that the scale of CO2 emissions will require 34 amounts of long-term storage. Some propose storing the CO2 in coal mines or liquid storage in the ocean. Shell favors storing CO2 in deep geological structures such as saline (盐的) formations and 35 oil and gas fields that exist throughout the world.

单选题 Balancing College Life and Academics A. Control your Schedule; don't let your schedule control you. Organization and time management skills are two of the most valuable skills you will ever have. One of the first things you should do at the beginning of each semester is organize the dates of all class tests and project deadlines from each syllabus, and all required meetings and events from each organization. All obligations should then be logged into a centralized schedule you keep at all times, such as a daily planner, desk calendar, or even a PDA (personal digital assistant). For the next 4 months, you now know exactly what you must schedule the rest of your life around. B. Next, it is highly recommended for you to set a schedule for yourself in writing to include all other items you want to create as a routine. Most importantly, this should include times of study, such as every Tuesday and Thursday from 3:30-6:30. Physically block off these tinge periods every Tuesday and Thursday for the rest of the semester. Of course, the most important part of creating a schedule is sticking to it! So, be disciplined enough to schedule any other activities that are less important around those that are most important. C. Ask for help when you need it. Whether it involves academics or organizational responsibilities, everyone comes to a point where they feel overwhelmed. This is what friends, fellow members, and other university resources are there for. Unfortunately, there are several reasons why people don't seek help when it is available. Some people try to take on too much, trying to prove to themselves that 'I can do this all on my own'. Some may not want to admit to people that they 'can't handle everything.' Others may feel they must do everything all on their own, because only then will they know it will get done right and on time (an early signal of being a control freak). D. Academically, seek out help when you don't understand something. There should be plenty of resources available, from writing centers, to computer labs, to graduate assistants, to your professors who offer office hours. There are also other students who may understand that subject better, or who have even taken the course before. Especially in very large classes, some students may be intimidated to ask for help. But, the sole purpose of the institution and all of these resources is to help you learn. So use them. Ask for rope to be thrown down before you drown! E. Keep a firm grasp on your priorities. Understanding what your PRIORITIES are each and every day is one of the biggest keys to college success. It is also one of the easiest concepts to lose track of. It is a fast-paced world, where it is easy to become sidetracked with social activities, TV shows, video games, etc. Some people carry a card in their wallet, or even a card on their PC, where they list the top 1-5 priorities in their life. F. Everyone has exactly 24 hours each day. People who achieve more in life simply make better use of their 24 hours each day than everyone else. What you do with each of your 24 hours has as much to do with your success during college as any other factor. There is an old saying that 'if it's important enough to you, you make time for it.' Be sure that nobody is in charge of your tune except for you. It is one of the most valuable assets you have. G. Don't wait until the end of your college career to stop procrastinating (延迟). Whether it is an event or a semester project that is two months away, ask yourself each day 'What can be done now instead of later?' Write down when you are going to do something, not simply when something is due. Set deadlines for yourself, and put them in writing. Then stick to it. Most people procrastinate because the activity they are supposed to do is not as desirable as what they would rather be doing. However, if you complete tasks early, you can enjoy your leisure time worry-free. This is one of the biggest ways to alleviate stress. H. If it is the 3rd day of the month, and there is a project due on the 28th of the month, most students hardly have that project on the radar screen yet. Then, they see the project creep up on their calendar on the 24th or 25th, and they say 'Uh-oh! ' Further, they realize there is an event planned on the 26th, and they have to work at their part-time job on the 27th! This lack of planning is what leads to either missed deadlines, or turning a project in on time, but with poor quality. In addition to poor quality, it also led to undue stress for 4 days. One easy way to tackle projects ahead of time is to break the project down into several smaller ones. For example, instead of writing a 10-page paper in one night, write 1-page per day for 10 days, or 1-page every other day. This will save time, increase quality, and decrease stress. I. Go to class. That's right. Skipping class is one of the most dangerous, yet tempting habits on college campuses today. Sure, you might be able to miss a class here and there--perhaps even miss a lot of classes--and still pass if you cram hard enough. However, don't make things hard on yourself, make things easy. The more you attend class, the less you have to study, and the more time you have for the everything else you want or need to do. Professors also have a way of telling you what will be on the test, and explaining the answers in class--but you are only privy to that if you are actually in class. J. Try to get in the habit of forcing yourself to sit in the FRONT of the class, especially in large classes. Studies show that students retain more information, and pay more attention, even if they don't realize it. It also helps keep you awake. That usually allows you to take better notes, as well. K. Find a mentor or example of a great student lifer in your organization. Almost every organization has one or more students who are shining examples of the balance between extra-curricular activities and academics. They make the Dean's List every semester, hold an important office in the organization, work part-time, and even have a girlfriend or boyfriend. Everyone seems to ask 'How do they do it?' L. So, are they smarter than you? In most cases, ABSOLUTELY NOT! There have been literally millions of college students that were 'smart enough' to graduate, but who failed in the areas of time manage- ment, priorities, and responsibilities. So, understand the habits of those who are successful at balancing college life and academics. Ask them what their secrets are, and they will surely be willing to help. M. Have fun! Ok, so most college students don't need help with this tip, right? However, enjoy it while you can--you are only in college once! Many Americans recall their college days as the best time of their life. Believe it or not, professors, administrators, and us college speakers want you to enjoy every minute of it! Making efficient use of your time and controlling your schedule are important ingredients in being able to enjoy yourself. They allow you to alleviate stress and succeed both inside and outside the classroom, so you can have a BLAST during your college career. Good luck!

单选题 How Marketers Target Kids A. Kids represent an important demographic to marketers because they have their own purchasing power, they influence their parents' buying decisions and they are the adult consumers of the future. Industry spending on advertising to children has exploded in the past decade, increasing from a mere $100 million in 1990 to more than $2 billion in 2000. B. Parents today are willing to buy more for their kids because trends such as smaller family size, dual incomes and postponing children until later in life mean that families have more disposable income. As well, guilt can play a role in spending decisions as time-stressed parents substitute material goods for time spent with their kids. Here are some of the strategies marketers employ to target kids: Pester (纠缠) Power C. Today's kids have more autonomy and decision-making power within the family than in previous generations, so it follows that kids are vocal about what they want their parents to buy. 'Pester power'refers to children's ability to nag their parents into purchasing items they may not otherwise buy. Marketing to children is all about creating pester power, because advertisers know what a powerful force it can be. D. According to the 2001 marketing industry book Kidfluence, pestering or nagging can be divided into two categories—'persistence' and 'importance'. Persistence nagging (a plea, that is repeated over and over again) is not as effective as the more sophisticated 'importance nagging'. This latter method appeals to parents' desire to provide the best for their children, and plays on any guilt they may have about not having enough time for their kids. The Marriage of Psychology and Marketing E. To effectively market to children, advertisers need to know what makes kids tick. With the help of well-paid researchers and psychologists, advertisers now have access to in-depth knowledge about children's developmental, emotional and social needs at different ages. Using research that analyzes children's behaviour, fantasy lives, art work, even their dreams, companies are able to craft sophisticated marketing strategies to reach young people. F. The issue of using child psychologists to help marketers target kids gained widespread public attention in 1999, when a group of U.S. mental health professionals issued a public letter to the American Psychological Association (APA) urging them to declare the practice unethical. The APA is currently studying the issue. Building Brand Name Loyalty G. Canadian author Naomi Klein tracks the birth of'brand' marketing in her 2000 book No Logo. According to Klein, the mid-1980s saw the birth of a new kind of corporation—Nike, Calvin Klein, Tommy Hilfiger, to name a few—which changed their primary corporate focus from producing products to creating an image for their brand name. By moving their manufacturing operations to countries with cheap labour, they freed up money to create their powerful marketing messages. It has been a tremendously profitable formula, and has led to the creation of some of the most wealthy and powerful multi-national corporations the world has seen. H. Marketers plant the seeds of brand recognition in very young children, in the hopes that the seeds will grow into lifetime relationships. According to the Center for a New American Dream, babies as young as six months of age can form mental images of corporate logos and mascots. Brand loyalties can be established as early as age two, and by the time children head off to school most can recognize hundreds of brand logos. While fast food, toy and clothing companies have been cultivating brand recognition in children for years, adult-oriented businesses such as banks and automakers are now getting in on the act. Buzz or Street Marketing I. The challenge for marketers is to cut through the intense advertising clutter (杂乱) in young people's lives. Many companies are using 'buzz marketing' —a new twist on the Ned-and-true 'word of mouth' method. The idea is to find the coolest kids in a community and have them use or wear your product in order to create a buzz around it. Buzz, or 'street marketing', as it's also called, can help a company to successfully connect with the elusive (难找到) teen market by using trendsetters to give them products 'cool' status. J. Buzz marketing is particularly well-suited to the Internet, where young 'Net promoters' use chat rooms and blogs to spread the word about music, clothes and other products among unsuspecting users. Commercialization in Education K. School used to be a place where children were protected from the advertising and consumer messages that permeated their world—but not anymore. Budget shortfalls (亏空，差额) are forcing school boards to allow corporations access to students in exchange for badly needed cash, computers and educational materials. L. Corporations realize the power of the school environment for promoting their name and products. A school setting delivers a captive youth audience and implies the endorsement of teachers and the educational system. Marketers are eagerly exploiting this medium in a number of ways, including: 1)sponsored educational materials; 2)supplying schools with technology in exchange for high company visibility; 3)advertising posted in classrooms, school buses, on computers in exchange for funds; 4)contests and incentive programs: for example, the Pizza Hut reading incentives program in which children receive certificates for flee pizza if they achieve a monthly reading goal; 5)sponsoring school events. The Internet M. The Internet is an extremely desirable medium for marketers wanting to target children. It's part of youth culture. This generation of young people is growing up with the Internet as a daily and routine part of their lives. Kids are often online alone, without parental supervision. Unlike broadcasting media, which have codes regarding advertising to kids, the Internet is unregulated. Sophisticated technologies make it easy to collect information from young people for marketing research, and to target individual children with personalized advertising. Marketing Adult Entertainment to Kids N. Children are often aware of and want to see entertainment meant for older audiences because it is actively marketed to them. In a report released in 2000, the U.S. Federal Trade Commission (FTC) revealed how the movie, music and video games industries routinely market violent entertainment to young children. O. The FTC studied 44 films rated 'Restricted', and discovered that 80 per cent were targeted to children under 17. Marketing plans including TV commercials run during hours when young viewers were most likely to be watching. The FTC report also highlighted the fact that toys based on characters from mature entertainment are often marketed to young children. Mature rated video games are advertised in youth magazines; and toys based on 'Restricted' movies and M-rated video games are marketed to children as young as four.
