Question: Read the article and select the best answer. Article: Each year,millions of children around the world are unable to go to school.To draw attention to this widespread problem,the United Nations (UN) is putting education first.Recently,the UN screened a documentary film called Back to School.The film is the second in a series of documentaries for the project Time for School. These films follow seven children from seven different countries.This 12year project began in 2003,when the children first started school."This is something we could do to help the education crisis in the world,"said producer and writer Judy Katz."Documentary filmmakers can get deeply involved in a problem and do something about it." More than 100 million children will never set foot in a school.Sixty percent of those children are girls.Cheryl Faye,head of the UN Girls Education Initiative,spoke about the many factors that prevent girls from getting an education.One problem is the long distance many children must travel to get to school.Also,girls in many cultures are traditionally expected to marry early and work to help their families."We need to make a special effort for girls,"Faye said. As part of the UN's Millennium goals,the organization wants every single child to get at least an elementary education by 2015. Students from Lawrence Middle School in New York were deeply moved after they saw the film.The seventhgrade class is raising money to help build a library on the outskirts of Nairobi,Kenya,where Joab--a child in the documentary--lives.The class teacher,Karen Weiner,and the class are known in their school as the "Kenya crew".All the kids were really happy to support Joab and said they felt great about their fundraising efforts.Like the seventhgraders at Lawrence Middle School,kids can work together to make a difference in places like Nairobi.By raising money for education,kids can help children on the other side of the world have a chance of a better,happier life. Question: Why are the class teacher,Karen Weiner,and the class considered as "Kenya crew"? Options: A: Because they are trying their great efforts to raise money for the education of Kenya Children. B: Because they are actors in the documentary film Back to School. C: Because they are mostly from Kenya,where the child in the documentary lives. D: Because they all have the same experience as Joab,the Kenya child.
Answer: A

Question: Read the article and select the best answer. Article: Swearing can provide effective relief from pain - but not if you swear all the time, researchers have found. A study found releasing the strange expletive (=swearing) helped people cope with discomfort in the short-term but the frequency of swearing played an important role. Researchers at Keele University's School of Psychology employed 71 undergraduates who were asked to carry out a cold-water challenge while either repeating a swear word or a non-swear word. The students put their hand in room temperature water for three minutes to act as a control before diving it into cold 5degC water for as long as they could while repeating their word. The level of sensed pain together with a change in heart rate were compared while people swore or said their non-swear word. The group was also asked about how much they swore in daily life and this was analyzed together with their level of pain tolerance. Writing in the Journal of Pain, the authors concluded: "Swearing increased pain tolerance and heart rate compared with not swearing." "Moreover, the higher the daily swearing frequency, the less was the benefit for pain tolerance when swearing, compared with when not swearing." Dr Richard Stephens, a senior lecturer in psychology at Keele, said: "Swearing is a very emotive form of language and our findings suggest that using swear words moderation (, ) can be an effective and readily available short-term pain reliever." "However, if you're used to swearing all the time, our research suggests you won't get the same effect." Question: The purpose of this research mentioned in the passage is _ . Options: A: to encourage people to swear when they feel pain. B: to explain the benefits of swearing. C: to indicate the relation between swearing and pain tolerance. D: to prove that people repeating a swear word are stronger than non-swear speakers.
Answer: C

Question: Read the article and select the best answer. Article: "The world's oceans are slowly getting more acidic." say scientists. The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere. The lowering of the waters' PH value is not great at the moment but could cause a serious threat to current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature. Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century. These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change. "This level of acidity will get much more extreme in the future if we continue releasing CO2into the atmosphere," said Dr Caldeira. "And we predict the amount of future acidity will exceed anything we have seen over the last several hundred million years." However, it is not ly clear what that means for ocean life. Most organisms live near the surface, where the greatest PH change would be expected to occur, but deep-ocean life forms may be more sensitive to PH changes.Coral reefs and other organisms whose shells contain calcium carbonate may be affected if the water's acidity levels keep going up, the team predict. In recent years some people have suggested storing carbon dioxide from power stations in the deep ocean as a way of dealing with global warming.But Dr Caldeira said that such a strategy should now be re-considered. "Previously, most experts had looked at ocean absorption of carbon dioxide as a good thingbecause in releasing CO2into the atmosphere we warm the planet, and when CO2, is absorbed by the ocean, it reduces the amount of greenhouse warming." Question: The purpose of this passage is to _ . Options: A: show people the findings of a research team B: inform people of how acid the ocean is now C: introduce Dr Caldeira and his team's research D: warn people of the higher level of CO2
