PROBLEM: Article: I was doing my last-minute Christmas shopping in a toy store, looking at fashion dolls. A nicely-dressed little girl with her father was excitedly looking through the same dolls as well. As she was looking, a boy wandered in and sorted through some of the video games. He was dressed neatly, but in clothes that were obviously rather worn. He, too, had money in his hand, but it seemed to be no more than five dollars or so at the most. He was with his father as well, but each time he picked one of the video games and looked at his father, his father shook his head. The little girl had apparently chosen her doll, a beautifully-dressed glamorous creation that would have been the envy of every little girl on the block. However, she stopped to watch the little boy and his father. Then, the little girl put her carefully-chosen doll back on the shelf, and ran over to the video games. She excitedly picked up one that was lying on top of the other toys and raced towards the reception desk after speaking with her father. I picked up my purchases and waited in line behind them. Then, much to the little girl's obvious delight, the little boy and his father stood behind me. After the video game was paid for and bagged, the little girl handed it back to the cashier and whispered _ in her ear. The cashier smiled and put the package under the counter. I paid for my purchases and was rearranging things in my purse when the little boy came up to the cashier. The cashier rang up his purchases and then said, "Congratulations, you have been selected to win a prize!" With that, she handed the little boy the video game, and he could only stare in disbelief. It was, he said, exactly what he had wanted! The little girl and her father were standing at the door-way during all of this, and I saw the biggest, prettiest smile on that little girl's face that I have ever seen in my life.
Question: Which of the following is TRUE according to the passage?
Options: (A) The little boy got the video game because he was selected to win the prize. (B) The little girl chose the video game as her present. (C) The little girl chose the video game as well as the doll as her presents. (D) The little boy was too surprised to believe what had happened in the end.

SOLUTION: D

PROBLEM: 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

SOLUTION: B

PROBLEM: Article: For Yali Liu, the hardest thing about UK higher education is having to go to the pub. "It's how much you need to invest socially with other students," she says. "I don't like going to a pub or club, but people just keep going out and I feel the pressure to go out too." This is because, unlike in China, she says, there is so much emphasis during the course on teamwork and group projects, so socialising with other students - especially British people, is crucial. Liu, 23, who is in her final year of a BSc in business administration at the University of Bath, is one of more than 80,000 Chinese students studying in UK universities. They are responsible for a large proportion of the more than PS10bn a year that international students contribute to the UK economy. However, research shows that where their academic attainment is concerned, the picture is not satisfactory. While nearly 58% of all students - and 45% of overseas students graduated with a first-class degree last year, this was true of only 35% of students from China. To find an explanation, Zhiqi Wang and Ian Crawford, lecturers at the University of Bath, compared the performance of Chinese and British undergraduates in each year of their degree. Taking a sample of 100 British and Chinese students and comparing their average marks and final degree classification, they found a dramatic drop in performance among the Chinese students between year one, when they performed better than their UK counterparts, and year two, when they performed worse. They believe the drop results from two factors. First, Chinese students fail to adapt their approaches to learning and so their performance declines in the later years when the complexity of the work increases. Second, many young people in China enroll in higher education due to pressure from family rather than their own motivation. Professor Sedghi thinks part of the problem may be the changing socio-economic background of Chinese undergraduates. While 85% of Chinese students at British universities before 2000 were mature students, often funded by the government, since 2004, however, they have been younger, most funded by their families. Maybe UK institutions need to work harder to take into account what a big challenge it is for young people from a radically different culture and linguistic background to adapt to life in the UK. "We need to do more, contacting students before their arrival, assigning them tutors, encouraging peer-assisted learning, for example," says Sedghi.
Question: What can be inferred about Yali Liu from the passage?
Options: (A) She is not good at socialising with local students. (B) She is bored with the teamwork and group projects. (C) Her family can't afford her education in the UK. (D) The university won't award her a first-class degree.
