Ques: Read the article and select the best answer. Article: Scientists discovered 163 new species in Southeast Asia's Greater Mekong region last year,but all are at risk of extinction due to climate change,the WWF said in a report released Friday. The newly discovered creatures include a birdeating frog with fangs ,a bird that would rather walk than fly and a gecko whose alien appearance inspired the report's title of "Close Encounters",the conservation group said. The report was released ahead of major UN talks on climate change in Bangkok next week,which are being held before a makeorbreak summit in Copenhagen this December. "Some species will be able to adapt to climate change,and many will not,potentially resulting in massive extinction," Stuart Chapman,director of the WWF Greater Mekong program,said in the report."Rare and endangered species like those newly discovered are especially vulnerable because climate change will further shrink their already restricted habitats," he said. "The new discoveries in 2010 include 100 plants,28 fish,18 reptiles,14 amphibians,2 mammals and a bird,"the WWF report said.The area spans Cambodia,Laos,Myanmar,Thailand,Vietnam and China's Yunnan Province. "Among the new species is the birdeating fanged frog,which remains hidden in a protected area of Thailand despite the fact that scientists are studying there for 40 years," the report said. The tigerstriped pit viper was discovered accidentally on an island off the coast of Vietnam when a scientist was looking for a lizard and his son pointed out that his hand was on a rock right next to the snake's fangs."We caught the snake and the gecko and they both proved to be new species," researcher Lee Grismer of La Sierra University in California was quoted as saying in the report.The leopard gecko,found on another Vietnamese island,has the coloring of a leopard and bizarre orange,catlike eyes and thin legs. The Greater Mekong region has proved a rich area for scientists.The WWF said in December 2010 that it had found 1,068 new species there between 1997 and 2009. Question: What is special about the newly discovered bird? Options: A: It usually walks. B: It likes walking and flying. C: It can eat other birds. D: It can eat frogs.
Ans: A

Ques: Read the article and select the best answer. Article: We can begin our discussion of "population as a global issue" with what most person mean when they discuss " the population problem": too many people on earth and a too rapid increase in the number added each year. The facts are not in dispute. It was quite right to employ a similar matter that linked demographic growth to " a long, thin power fuse that burns steadily from time to time until it finally reaches the limit, and explodes". To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history. We find that population have been really stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. For most of human history, it was seldom the case that one in ten persons would live past forty, where infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birth rates. Thus, the population problem throughout most of history was how to prevent extinction of the human race. This pattern is important to know. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden enthusiasm for more children, but an improvement in the conditions that traditionally have caused high rate of death. Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8000B.C. till approximately 1650 A.D. And a period of rapid growth since 1650. In the first period of some 9,600 years, the population increased form some 8 million to 500 million in 1650. Between 1650 and the present, the population has increased from 500 million to more than 4 billion. And it is estimated that by the year 2020 there will be 8... Question: According to the passage, "population as a global issue" _ . Options: A: is quite unlike the population problem and thus doesn't need our concern B: focuses on tracking down the reason of rapid population growth C: deals with the same problem aroused by the population problem D: will manage the population growth problem from global perspectives
Ans: C

Ques: Read the article and select the best answer. Article: If cars had wings , they could fly and that just might happen, beginning in 2011. The company Terrafugia, based in Woburn, Massachusetts, says it plans to deliver its carplane, the Transition, so customers by the end of 2011. "It's the next'wow'vehicle,"said Terrafugia vice president Richard Gersh."Anybody can buy a Ferrari, but as we say, Ferraris don't fly." The carplane has wings that unfold for flying-a process the company says takes one minute-and fold back up for driving. A runway is still required to take off and land. The Transition is being marketed more as a plane that drives than a car that flies, although it is both. The company has been working with FAA to meet aircraft regulations, and with the National Highway Traffic Safety Administration to meet vehicle safety regulations. The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly. They say it saves you the trouble from trying to find another mode of transportation to get to and from airports: You drive the car to the airport and then you're good to go. When you land, you fold up the wings and hit the road. There are no expensive parking fees because you don't have to store it at an airport-you park it in the garage at home. The carplane is designed to fly primarily under 10,000 feet. It has a maximum takeoff weight of 1,430 pounds, including fuel and passengers. Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under the bad weather instead of flying into marginal conditions. The Transition's price tag:$ 194,000. But there may be additional charges for options like a radio, a transponder or a GPS. Another option is a fullplane parachute. "If you get into a very awful situation,it is the necessary safety option,"Gersh said. So far, the company has more than 70 orders with deposits."We're working very closely with them, but there are still some remaining steps,"Brown said. Question: What's the best title for the passage? Options: A: Cars with wings may be just around the corner B: Which to choose:a Ferrari or a carplane? C: A more convenient and cheaper way to fly D: Cars with wings can fly as fast as planes
Ans:
A
