I'm taking a test and have to guess the right answer to the question after the article. Article: "I sometimes get up at three or four in the morning and I surf the net." "I often check my e-mail forty times a day. " "I often spend more than three hours during one time on the net." "I spend more time in chat rooms than with my 'real-life' friends." Do you know any people like these? They are part of a new addiction called Internet addiction. Internet addicts spend at least thirty to forty hours online every week. The use of the Internet can be an addiction like drug use. People lose control of the time they spend on the Internet. For example, one college student was missing for several days. His friends were worried, and they called the police. The police found the student in the computer lab: he was surfing the net for several days straight. Studies show that about 6% to 10% of Internet users become addicted. And people worry about the teens because the Internet is changing the playing field for some of them. They spend more time in cyberspace than in the real world of friends and family. Is "surfing the net" a hobby or an addiction for you? You may have a problem if you have these symptoms : 1You do not go to important family activities or you do not do school work because you like to spend hours on the Internet. 2You can't wait for your next online time. 3You go out with your friends less and less. 4You plan to spend a short time online, but then you spend several hours. Question: Why do people worry about the teens? Options: A: The teens are wasting too much money. B: They used to work on the Internet. C: The playing field of the teens will disappear. D: More and more of the teens will become addicted to the Internet.

I'm taking a test and have to guess the right answer to the question after the article. Article: Pollutants coming from automobile operation have begun to cause many environmental problems. It has been calculated, for example, that 70% of the carbon monoxide , 45% of the nitrogen oxides , and 34% of the hydrocarbon pollution in the United States can be traced directly to automobile exhausts . In addition, rubber, motor oil and other materials accumulate on roadways and are washed into streams, with effects nearly as serious as those of untreated waste water. In an effort to improve the situation, the U.S. government has made regulations on the use of the constituents of automobile exhaust gas that are known to cause air pollution. These constituents fall roughly into three types: hydrocarbons that pass through the engine unburned; carbon monoxide, also a product of incomplete burning; and nitrogen oxides which are formed when nitrogen and oxygen are in contact at high temperatures. Besides their own poisonous character, hydrocarbons and nitrogen oxides react in the presence of sunlight to form harmful smog. Carbon monoxide and hydrocarbons are rather easily controlled by the use of higher burning temperatures in engines. Unfortunately, the conditions that produce minimum emission of hydrocarbons tend to raise emission of nitrogen oxides. In a way this difficulty is solved by adding recycled exhaust gas to the fuel mixture, thus avoiding the oversupply of oxygen that favors formation of nitrogen oxides. California, which has the most strict air-pollution laws in the United States, requires further special compounding of gas to control emissions, and several states have ordered that alcohol be mixed with gas, as this will reduce emissions of the carbon monoxide by 35 per cent and the hydrocarbons by 15 per cent. Question: According to the text, alcohol is added to gas in order to _ . Options: A: increase awareness of environment protection B: control air pollution C: increase the fuel efficiency D: replace gas gradually

I'm taking a test and have to guess the right answer to the question after the article. Article: Today, innovations to make our lives more eco-friendly can be found everywhere. There are energy-efficient automobiles, eco-friendly light bulbs, and clothes made by fashion designers using sustainable environmental practices. Industries around the world have also begun to take a serious look at how their operations affect the local and global environment. The university of Colorado has been named one of the top green colleges and universities in the United States. This university was one of the first to start a student-led recycling program in the 1970s and today supplies students with reusable shopping bags to use both on and off campus. The entire University of Colorado also uses low flow water fixtures and has reduced water usage by 40 percent since 2002. When it comes to going green, Warren Wilson College has been recognized in many places. The Sierra Club and The Princeton Review have named the college as one of America's greenest colleges and universities, while the school has also received the Outstanding College Recycling Award from the Carolina Recycling Association, as well as awards from the Association for the Advancement of Sustainability in Higher Education(AASHE). For a small college, Warren Wilson has made enormous efforts to be an eco-friendly campus since its beginning, and today owns a campus farm, a seeding program, and an extensive recycling program. Warren Wilson was also the first College to have an LEED platinum certified residence hall, and its building services department is also 100 percent GreenSeal certified. According to College Stats, Warren Wilson College is one of the first institutions in the United States to be almost completely self-sufficient while also engaging students to incorporate sustainability into all academic programs. Going green efforts at Oberlin College have not gone unnoticed. Oberlin College spends 22 percent of its food budget on buying food from local farmers, with most of the food raised or harvested with organic and sustainable practices.... Question: Students in Oberlin College can _ . Options: A: grow their own food on campus B: pay less with their own containers C: help the college make its food budget D: recycle paper at their graduation ceremony

I'm taking a test and have to guess the right answer to the question after the article. Article: Although hurricane season doesn't begin until June 1, a Pacific storm has already struck. El Salvador, which was ruined by a Caribbean storm in 1995, was hit by Hurricane Adrian on Friday. This is the first Pacific-born hurricane to ever reach land in this Central American country. Some 14,000 people left from the western coast of El Salvador. The storm weakened as it crossed land, heading east. Heavy rains created deadly flooding problems in the hurricane' s wake. Adrian is the first Pacific storm of the season. It reported maximum continuous winds of 75 miles per hour, the minimum strength of a hurricane. A Category 3 hurricane, Adrian also caused damage and flooding in Honduras. It is expected to break up before reaching the Caribbean Sea on the eastern coast of Central America. Hurricane season typically begins June 1 and lasts through November 30. The National Oceanic and Atmospheric Administration (NOAA) has predicted seven to nine hurricanes for the 2005 season. "It is difficult to make any kind of an exact prediction of how many of these will strike land," NOAA administrator Conrad Lautenbacher said. He predicts two to three hurricanes will strike the U.S. this season. Last year, six of nine hurricanes reached Category 3 strength or higher. Four of those hit Florida within a six-week period. Altogether, Hurricanes Charley, Frances, Ivan, and Jeanne caused more than $40 billion in damage in the Sunshine State. This year' s forecast is based on ocean temperatures. Warmer temperatures produce more tropical storms, which can then turn into hurricanes. "The issue, really, this year is the unusually warm sea surface temperatures in the Atlantic," said Frank Lepore of the National Hurricane Center. Question: We can infer that warmer ocean temperatures _ . Options: A: have nothing to do with the hurricane B: cause less hurricane C: are mo re likely to cause the hurricanes D: do a lot of damage to the areas along the coast
