Ques: Read the article and select the best answer. Article: Scientists have long understood the key role that oceans play in regulating the Earth's climate. Oceans cover 70 percent of the globe and store a thousand times more heat than the atmosphere does. What's newer is the understanding of how this key component of our climate system responds to global warming. A brake on global warming -- for now One of oceans'most important climate functions is absorbing heat and carbon dioxide (CO2), one of the gases that cause global warming. Acting as a heat sponge , oceans have absorbed huge amounts of heat and CO2in the last forty years. Fujita explains that "oceans are saving us from faster climate change -- they are a big flywheel that delays rapid overheating of the Earth, putting a brake on the climate system." "That's the good news," he adds. "The bad news is that oceans only slow the atmospheric warming. Once oceans come to balance with a greenhouse gas warmed earth, the extreme heat will remain in the atmosphere and things will get much hotter." But where and how oceans release this accumulated heat is uncertain. And as oceans store heat, fragile underwater ecosystems are struggling. The most recent scientific report from the Intergovernmental Panel on Climate Change (IPCC) also notes with concern that oceans are acidifying because of increased absorption of atmospheric CO2, and thus causing a threat for shell-forming species. Sharp increases in carbon dioxide levels will cause further acidification of oceans. Currents distributing heat Another important role oceans play is that of distributor. Oceans deliver heat and life-sustaining nutrients around the globe. Just as blood vessels bring oxygen and nutrients to cells in the human body, oceans' currents carry oxygen, nutrients and heat throughout the Earth. Oceans distribute 25 percent to 50 percent of the energy the planet receives from the sun. For example, the Gulf Stream carries heat across the Atlantic. This warm current gives northwestern Europe a milder climate than it would normally have so far north. A... Question: We can infer from the passage that _ . Options: A: oceans cause global warming B: oceans stop global warming C: oceans release nutrients and heat D: ocean ecosystems face more dangers
Ans: D

Ques: Read the article and select the best answer. Article: In the United States alone,over 100 million cell-phones are thrown away each year.Cell-phones are part of a growing mountain of electronic waste like computers and personal digital assistants.The electronic waste stream is increasing three times taster than traditional garbage as a whole. Electronic devices contain valuable metals such as gold and silver.A Swiss study reported that while the weight of electronic goods represented by precious metals was relatively small in comparison to total waste,the concentration of gold and other precious metals was higher in So-called e-waste than in naturally occurring minerals. Electronic wastes also contain many poisonous metals.Even when the machines are recycled and the harmful metals removed,the recycling process often is carried out in poor countries,in practically uncontrolled ways which allow many poisonous substances to escape into the environment. Creating products out of raw materials creates much more waste material,up to 100 times more,than the material contained in the finished products.Consider again the cell-phone,and imagine the mines that produced those metals,the factories needed to make the box and packaging it came in.Many wastes produced in the producing process are harmful as well. The U.S Environmental Protection Agency notes that most waste is dangerous in that"the production, distribution,and use of products-as well as management of the resulting waste-all result in greenhouse gas release." Individuals can reduce their contribution by creating less waste at the start-for instance,buying reusable products and recycling. In many countries the concept of extended producer responsibility is being considered or has been put in place as an incentive for reducing waste.If producers are required to take back packaging they use to sell their products,would they reduce the packaging in the first place? Governments' incentive to require producers to take responsibility for the packaging they produce is usually based on money.Why,they ask,should cities or... Question: By mentioning the Swiss study,the author intends to tell us that _ . Options: A: the weight of e-goods is rather small B: natural minerals contain more precious metals C: E-waste deserves to be made good use of D: the percentage of precious metals is heavy in e-waste
Ans: B

Ques: Read the article and select the best answer. Article: Two years ago, Wendy Hasnip, 47, experienced a brain injury that left her speechless for two weeks. When she finally recovered, she found herself talking with what seemed to be a French accent: "I phoned a friend the other day, and she spent the first ten minutes laughing," Hasnip said at the time. "While I have nothing against the French." Hasnip suffered from foreign accent syndrome , a rare condition in which people find themselves speaking their own language Like someone from a foreign country. The condition usually occurs in people who have experienced a head injury or a stroke a sudden loss of consciousness, sensation, or movement caused by a blocked or broken blood vessel in the brain. The condition was first identified during the Second World War in a Norwegian woman whose head was injured during an attack by the German military. The woman recovered but was left with a German-sounding accent, to the horror of fellow villagers who avoided her after that. Researchers have discovered that the combined effect of the damage to several parts of the brain makes victims lengthen certain syllables, mispronounce sounds, and change,the normal pitch of their voice. Those changes in speech add up to what sounds like a foreign accent. Another researcher, a phonetician ,says victims of the syndrome don't acquire a true foreign accent. Their strangely changed speech only resembles the foreign: accent with which it has a few sounds in common. When an English woman named Annie recently developed foreign accent syndrome after a stroke, she spoke with what seemed to be a Scottish accent. However, Annie's Scottish coworkers said she didn't sound at all like a Scot. Question: According to the passage; people _ may have foreign accent syndrome. Options: A: whose parent has experienced a head injury B: who have lived in a foreign country for a long time C: who have lost their consciousness owing to a stroke D: who have learned foreign language from their coworkers
Ans:
C
