Question: Article: Teenagers in the UK and the US get to watch some wonderful TV shows. Why not have a look at a few of them yourself and take the chance to practice your English at the same time? Modern Family Network: ABC Number of seasons: 3 The TV drama features two families, modern and traditional. The first is a typical American family with 3 adolescent children. Claire is a traditional mom, while Phil, the father, wants to be friends with his three children; he can name all the songs in the hit film High School Musical. The second family is made up of a 60- year-old man, Jay, his attractive young Latin American wife, Gloria , and her 11-year-old son, Alex. Jay is 30 years older than Gloria and everyone thinks they are father and daughter. 2 Broke Girls Network: CBS Number of seasons: 1 Max Black is a cafe waitress and babysitter in Brooklyn, New York; Caroline Channing is the daughter of a Manhattan millionaire. Neither of them ever imagined making friends with the other. But when Caroline loses all of her fortune after her father goes to prison, she applies for a job as a waitress in the same cafe and has to learn from Max. Problems are unavoidable, but luckily, kind-hearted girls can always make things work out. They turn out to be great at helping each other out in their endless struggle against strange customers and picky bosses. Gradually a friendship develops. True Blood Network: HBO Number of seasons: 4 Vampires live on in countless books, movies and television shows. If the Twilight series got you interested in vampire myths, then look no further than True Blood for another exciting adventure. Sookie Statckhouse is a small-town waitress. She is also telepathic . A meet with Bill Compton in a bar turns her life upside down. Bill is a vampire and that night Sookie saves him from a murder attempt. Sookie then becomes involved in a series of murder cases. The love between Sookie and Bill adds a touch of romance to a thrilling story. Merlin Network: BBC Number of seasons:4 King Arthur is one of the most important mythical figures in England. But the BBC tells a slightly different story from the legend. Instead of focusing on Arthur, it is Merlin, the wizard who helps Arthur all the way through his adventures, who takes the lead role. Rather than the wise old wizard who instructs Arthur in the legend, the TV dram turns him into a handsome young man. Merlin meets Arthur in the kingdom of Camelot and believes that he is an arrogant bully . Arthur, likewise, has a less than great opinion of Merlin. The series focuses on how a friendship grows between the two.
Question: The TV drama Modern Family probably tells _ .
Options: (A) the way that friendship develops in different families (B) the idea that people need to be appreciated one way or another (C) what life in the US is like and an image of contemporary US society (D) the message that it is good to be who you are, regardless of what others think

Answer: C

Question: Article: In the atmosphere, carbon dioxide acts rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from escaping According to a weather expert's prediction , the atmosphere will be 3degC warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate.If this warming up took place.the ice caps in the poles would begin to inch,thus raising sea level several meters and severely flooding coastal cities.Also.the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere ,possibly resulting in an alteration of the earth's chief food growing zones. In the past,concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet.But the weather experts are now paying more attention to West Antarctic.which may be affected by only a few degrees of warming,in other words,by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels. Satellite pictures show that large areas of Antarctic ice are already disappearing.The evidence available suggests that a warming has taken place.This fits the theory that carbon dioxide warms the earth. However, most of the fuel is burnt in the northern hemisphere,where temperatures seem to be falling.Scientists conclude,therefore ,that up to now natural influences on the weather have gone beyond those caused by man.The question is:Which natural cause has most effect on the weather? One possibility is the variable behavior of the sun.Astronomers at one research station have studied the hot spots and 'cold' spots (that is, the ly less hot spots)on the sun.As the sun rotates ,every 27.5 days,it presents hotter or colder faces to the earth,and different aspects to different parts of the earth.This seems to have a considerable effect on the distribution of the earth atmospheric pressure,and consequently on wind circulation.The sun is also changeable over a long term:its heat output goes up and down in cycles,the latest trend being downward. ' Scientists are now finding shared relations between models of solar weather interactions and the actual climate over many thousands of years,including the last ice Age.The problem is that the models are predicting that the world should be entering a new Ice Age and it is not.One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia of the earth's climate.If this is right, the warming effect of carbon dioxide might thus be serving as a useful opposed balance to the sun's fading heat.
Question: It can be concluded that a concentration of carbon dioxide in the atmosphere would_.
Options: (A) mean a warming-up in the Arctic (B) raise the temperature of the earth's surface (C) prevent the sun's rays from reaching the earth's surface (D) explain the cause of great changes in the climate in the northern hemisphere

Answer: B

Question: Article: Viruses come in an enormous number of shapes and forms.As we begin to understand them more,the hope is we might be able to control them better, says Carl Zimmer.And who knows,the day might come when we can treat them as friends not enemies. Science writer Carl Zimmer says that in his utopia there would be a global public health system with sophisticated drugs and vaccines to deal with any virus that could cause us trouble. Viruses are by far the most abundant life form on Earth.If you took all the stars in the universe and multiplied that number by a million,that's how many viruses we think are on the planet. Zimmer thinks we should face the future with a mixture of optimism and preparing for the worse.He thinks we will face some unknown virus that will cause a lot of damage-history tells us that this is so.We do understand viruses a lot better now, and there is great hope that one day we'll be able to find a drug that c. an kill any virus.But this research is at a very preliminary stage,and it will be a number of years before we see whether this type of universal anti--viral drug could actually work. Viruses are very versatile and clever, and so there are things that they can do for us.Some scientists are using viruses as engineers to assemble solar panels, others are using viruses to manufacture proteins that could be used as drugs.So,maybe in the future we won't think of viruses as our enemies,but instead view them as our friends.
Question: Science writer Carl Zimmer wishes that _
Options: (A) a global health system could be set up to produce drugs (B) all the countries could produce drugs and vaccines for each other (C) all the countries could work together to cope with any trouble caused by viruses (D) complicated drugs and vaccines could be traded among countries

Answer:
C
