Q: I'm taking a test and have to guess the right answer to the question after the article. Article: The average global temperature has increased by almost 0.5 centigrade degree over the past century; scientists expect it to rise by an extra 1~3 degree over the next 100 years. Warmer weather makes glaciers melt, adding more water to the ocean. The warmer temperature also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10~25 cm in the last 100 years. The main cause of global warming is human pollution. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even warmer. Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The sea level could rise to one metre this century. Should this come true, millions of homes will be swallowed up by the sea and the world will be flooded with "climate refugees" looking for somewhere to live? Question: What do you think we should do? Options: A: Not use coal, oil and gas any more. B: Build the house on the mountain. C: Do our best to protect the environment. D: Lower the temperature.
A: C

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: With only about 1, 000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species . That's a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called "Noah's Ark". Noah's Ark is aimed at collecting eggs, embryos , semen and DNA of endangered animals and storing them in liquid nitrogen . If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M's College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future. It is estimated that as many as 2,000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years. This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal. The entire procedure could take from three to five years to complete. "The nuclear transfer of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem," Kraemer believes. "They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it's difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort," adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog. "They are trying to do something that's never been done, and this is very similar to our work in Noah's Ark. We're both trying to save animals that face extinction. I certainly appreciate their effort and there's a lot we can learn from what they are attempting to do. It's a research that is very much needed. " Question: According to Professor Kraemer, the major problem in cloning pandas would be the lack of _ . Options: A: available panda eggs B: host animals C: qualified researchers D: enough money
A: A

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Do you enjoy seeing the stars twinkling at night? Or do you love the ocean and sea, diving and racing with lovely dolphins? With heavy burdens on their shoulders, teenagers find it hard to pull out. Even if they are free, they prefer to occupy themselves with computer games or watching TV. How to get children away from screens is a great concern for parents. Now there is some good news for those concerned parents and teachers. A campaign is being launched to encourage children to surrender 30 minutes of screen time a day to head for the great outdoors. The newly formed Wild Network, a collaboration of nearly 400 organizations, is attempting to attract youngsters away from television and computer screens and into fields, woods and parks. Organizers say it is the UK's biggest ever campaign to reconnect children with nature and outdoor play, and claim it could help improve fitness, mental alertness and general well-being. A documentary film, Project Wild Thing, will herald the launch at more than 50 cinemas across the UK from Friday. It looks at the increasingly fragile link between children and nature. Members of the network include the National Trust, RSPB, Play England and the NHS Sustainable Development Unit. Andy Simpson, chairman of Wild Network, said, "The tragic truth is that kids have lost touch with nature and the outdoors in just one generation." Time spent outdoors is down, roaming ranges have fallen drastically, activity levels are declining and the ability to identify common species has been lost. Suggestions of how to get more time in nature include collecting conkers , camping, snail racing, and observing autumn colors on trees. From January, the network will aim to make suggestions to politicians on how government can do more _ This is not the first time the message of fewer screens, more play has been brought up. Children in the 1980s were entreated to do the same by the BBC TV series Why Don't You, which somewhat confusingly called on its viewers to "switch off your TV set, and go to do... Question: According to the organizers of Wild Network, there will be many advantages from the campaign EXCEPT _ . Options: A: improving health conditions B: keeping touch with nature C: learning more about wildlife D: teaching children how to make full use of their spare time
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: CANBERRA (Reuters Life!) - Think twice before eating those dropped crumbs off your computer keyboard -- you might as well be eating off a toilet seat, according to a new study on the amount of germs on keyboards. A study by British "Which? Computing" asked a microbiologist to examine for bugs on 33 keyboards in a typical London office, a toilet seat and a toilet door handle. Four keyboards were judged potential health hazards and the microbiologist recommended the removal of one keyboard as it had 150 times the pass limit of bacteria -- five times filthier than the swabbed toilet seat. "Most people don't give much thought to the grime that builds up on their PC, but if you don't clean your computer, you might as well eat your lunch off the toilet," said Sarah Kidner, the consumer magazine editor of "Which? Computing" in a statement. The study found that eating lunch at desks is the main cause of a bug-infested keyboard. Dropped crumbs and food encourages the growth of millions of bacteria. Poor personal hygiene, such as not washing hands after going to the toilet, may also add to the dirtiness of keyboards. But despite the health hazard of a dirty keyboard, a survey of 4,000 people by the magazine found one in 10 people ever cleaned their keyboard while another two in 10 never cleaned their mouse. Almost half -- or 46 per cent -- cleaned their keyboard less than once a month. To clear out bugs, the magazine recommends users unplug keyboards, turn them upside down and shake them. Question: What do you think the expression "Think twice before eating those dropped crumbs off your computer keyboard" stands for? Options: A: Think several times before eating beside your computer B: Don't drop foods onto the computer keyboard. C: Don't eat foods dropped onto the computer keyboard. D: Be careful when you are eating by the computer.
A: C
