单选题Excerpt 1: Sales of e-readers surged during the Christmas holiday season, according to a Pew Research Center report, which showed that the number of adults in the United States who owned tablets nearly doubled from mid-December to early January. Excerpt 2: Apple, based in Cupertino, California, controls 73 percent of the market, while Samsung Electronics Co., Sony Corp. and Toshiba Corp, are among companies making constant improvements on tablets Without bringing services that cut into the market share, Sarah Rotman Epps, an analyst at Forrester, said in the report. Excerpt 3: Under Square"s year-long pilot program, an iPad would be installed in the space where Taxi TVs currently sit, and the driver would have an iPhone to process credit-card payments. The technology would allow drivers to accept a passenger"s card at any point during the ride, then enter the amount later. The system charges drivers less in credit card transaction fees than the current rates. Excerpt 4: When Apple introduced the iPad tablet computer in 2010, it was doing what it likes to do best: creating a new category to dominate, as it had done with the iPod and iPhone. By the end of the year, the company had sold nearly 15 million iPads, generating about $9.5 billion in revenue. Just two years later, the chief executive of Apple, Timothy D. Cook, has a prediction: the day will come when tablet devices like the Apple iPad outsell traditional personal computers. Excerpt 5: Apple has made its first attempt to quantify how many American jobs can be credited to the sale of its iPads and other products, a group that includes the Apple engineers who design the devices and the drivers who deliver them-even the people who build the trucks that get them there. On Friday, the company published the results of a study it commissioned saying that it had "created or supported" 514,000 American jobs. The study is an effort to show that Apple"s benefit to the American job market goes far beyond the 47,000 people it directly employs here. Excerpt 6: People who read e-books on tablets like the iPad are realizing that while a book on a black- and-white Kindle is straightforward and immersive, a tablet offers a menu of distractions that can fragment the reading experience, or stop it in its tracks. E-mail lurks tantalizingly within reach. Looking up a tricky word or unknown fact in the book is easily accomplished through a quick Google search. And if a book starts to drag, giving up on it to stream a movie over Netflix or scroll through your Twitter feed is only a few taps away.

单选题Think of the ocean on a calm day. Ignoring the rise and fall of the waves, you might imagine the surface was dead flat the whole way across. You'd be wrong. Hills and valleys are as much as a feature of the sea as the land, although on a much smaller scale. These undulations have a variety of causes. Tides, currents, eddies, winds, river flow and changes in salinity and temperature push the sea level up in some places and down in others by as much as 2 meters. Ever tried swimming uphill? How do we map these oceanic hills and valleys? First, we need to know what the planet would look like without them. This is where the geoid (大地水准面) comes in. It is a surface where the Earth's gravitational potential is equal and which best fits the global mean sea level. It is approximately an ellipsoid, though uneven distribution of mass within the Earth means that it can vary from this ideal by up to 150 meters. The geoid represents the shape the sea surface would be if the oceans were net moving and affected only by gravity. Thus it can be used as a reference to measure any deviations in the ocean surface height that aren't caused by gravity—the hills and valleys, for instance, or any regional increase in sea level. So how do you measure the geoid and the ocean's irregular topography? It's complicated. Geophysicists calculate the geoid using data on variation in gravitational acceleration from several dozen satellites. The hills and valleys of the oceans are all very interesting, but can the geoid tell us anything more significant about the state of the planet? It certainly can. Knowing accurately where the geoid lies and how the Ocean surface deviates from it will help meteorologists spot changes in Ocean currents associated with climate change. The circumpolar current around Antarctic is one they are particularly interested in. It can also predict local climate variations produced by events such as El Nino, El Nino keeps warm water that would normally move westwards close to the coast of South America, deprives Southeast Asia of its monsoon rains, and increases rainfall on the west coast of the Ametlca. Since temperature changes cause changes in sea level, geoid-watchers should be able to prepare us before it strikes.

单选题Tight-lipped elders used to say,"It's not what you want in this world, but what you get．" Psychology teaches that you do get what you want if you know what you want and want the fight things. You can make a mental blueprint of a desire as you would make a blueprint of a house, and each of us is continually making these blueprints in the general routine of everyday living．If we intend to have friends to dinner,we plan the menu, make a shopping list, decide which food to cook first, and such planning is an essential for any type of meal to be served． Likewise, if you want to find a job, take a sheet of paper,and write a brief account of yourself． In making a blueprint for a job, begin with yourself,for when you know exactly what you have to offer,you can intelligently plan where to sell your services． This account of yourself is actually a sketch of your working life and should include education, experience and references．Such an account is valuable．It can be referred to in filling out standard application blanks and is extremely helpful in personal interviews．While talking to you, your could-be employer is deciding whether your education, your experience, and other qualifications will pay him to employ you and your"wares"and abilities must be displayed in an orderly and reasonably connected manner． When you have carefully prepared a blueprint of your abilities and desires, you have something tangible to sell．Then you are ready to hunt for a job．Get all the possible information about vour could—be job, make inquiries as to the details regarding the job and the firm．Keep your eyes and ears open, and use your own judgement．Spend a certain amount of time each day seeking the employment you wish for,and keep in mind：Securing a job is your job now．
