2、Why People Use Pseudonyms (假名字)?You can\'t choose the name you are given at birth, but in many countries you can change it legally when you reach adulthood. Of course, most people never change their names even if they feel unhappy about them. However some people do take this course of action－particularly artists! What makes an artist want to change their name? Sometimes it\'s fｏｒpurely ____ reasons, such as the Nobel Prize winning poet from Chile, Neftalf Reyes. He didn\'t want his father to know he was writing poetry, so he changed his name to Pablo Neruda when he was a young man. At other times the reason may appear strange, take the case of the Portuguese poet Femando Pessoa, who wrote under 75 different names. The reason? "When I use a different name, I always write in a different way," he explained. In most cases, however , people change their names fｏｒsocial, historical, political, ｏｒcultural reasons. Here are some of the most common: reason. The person\'s real name is just too long ａｎｄ　difficult to remember. Let\'s be honest, Madonna Louise Ciccone is not as easy to remember as just plain Madonna. ａｎｄ　short names are much easier to remember: William Bradley became Brad Pitt ａｎｄ　Edson Arantes do Nascimento became Pele.Sometimes names are changed fｏｒmarketing purposes. Fｏｒexample, if a name sounds too foreign, it may be changed to something that is more recognizable in a market. So in the film world, Ramon Estsvez adopted the name Martin Sheen. ｏｒmaybe the artist\'s real name doesn\'t sound attractive－Chad Everett does sound a lot better than Raymond Cramton.Artists sometimes choose the name of someone they admire. Robert Zimmerman changed his name to Boo Dylan because of his admiration fｏｒthe Welsh poet, Dylan Thomas.Another reason may be practical: in the past, women found it very difficult to get published. To avoid this situation, they sometimes gave themselves men\'s names, so the English authｏｒMary Ann Evans became George Eliot, ａｎｄ　she did get her books published!【单选题】

4、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas； it is also a potent greenhouse gas, ａｎｄ　once released into the atmospheres, it absorbs beat radiating from Earth\'s surface. That\'s why methane is a majｏｒcontributｏｒto the planet\'s increasing temperature rise ｏｒglobal warming. Molecule fｏｒmolecule, methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it\'s no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills ａｎｄ　wetlands.3 Greenhouse gases like methane ａｎｄ　carbon dioxide make up only a small part of Earth\'s atmosphere, which is 78 percent nitrogen ａｎｄ　nearly 21 percent oxygen. ａｎｄ　without greenhouse gases to trap the sun\'s heat ａｎｄ　warm the planet, life as we know it couldn\'t exist. But in the last200 years, human activity that requires burning oil, natural gas, ａｎｄ　coal fｏｒenergy has magnified the greenhouse effect.4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame fｏｒthis often focuses on big industries ａｎｄ　gas-guzzling vehicles. But agriculture plays a majｏｒrole, too. In the past 40 years alone, the global cattle population has doubled.5 Cows munch mostly grasses ａｎｄ　hay yet they grow big ａｎｄ　hefty. Why? Because of the rumen. The rumen holds 160 liters of food ａｎｄ　billions of microbes. These microscopic bacteria ａｎｄ　protozoa break down cellulose ａｎｄ　Fiber into digestible nutrients. A cow couldn\'t live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, ａｎｄ　goats, fｏｒexample), ａｎｄ　it makes them very gassy. It\'s part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, ａｎｄ　all this gas comes out. The average cow expels 600 liters of methane a day.That\'s why we say livestock gas is also a majｏｒfactｏｒof causing the global warming.Nothing has been mentioned in the passage about ____ .【单选题】

A.one of tire majｏｒcontributors

B.the ever-increasing atmospheric concentration of greenhouse gases

C.big ａｎｄ　hefty cows
