Part 2. Example
Article: Homework can put you in a bad mood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.
Question: Researchers did experiments on kids in order to find out _ .
Options: (A) how they really feel when they are learning (B) whether mood affects their learning ability (C) what methods are easy for kids to learn (D) the relationship between sadness and happiness
Answer: B
Explanation: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment. So, B is the correct answer.
Part 3. Exercise
Article: In the late 1500s, a large powerful gun was placed on top of the Signal Hill, in prefix = st1 /Newfoundland, to prevent attacks from the outside. Flags were also flown there to warn sailors of bad weather. It's fitting, then, the Italian Gulielmo Marconi should have chosen this site to receive the world's first radio signal -- in Morse code -- from England on December 12, 1901. Marconi, combining earlier ideas with his own, led us to a new communications age. For the next 50 years, until the appearance of television, radio ruled the air waves. Today, it's the TV that rules. No single person can say to have invented television. In 1884, the German Paul Nipkow invented a device that sent pictures mechanically , and in 1906, Boris Rosing, a Russian, used a ray and a disc to create the world's first TV system. Then in the early 1920s, another Russian, Vladimir Zworykin,invented a picture display tube. He took out a patent for color1 TV, even though it wouldn't be developed for another 25 years. In 1924, a Scot entered the scene -- John Logie Baird. He first succeeded in sending a moving picture and a year later got the first actual TV picture. In 1926, Baird showed TV in aLondonlaboratory. Two years later inNew York, Felix the Cat became the first TV star. TV excited everyone's imagination, but hardly anyone had a set, with just two thousand in use worldwide in the mid-1930s. Since the late 1940s, TV technology has developed very quickly. Computers may finally be combined with all televisions to give people a total all-in-one communications network. Today, it's possible to sit and watch TV in the middle of a forest or in the Arctic. It's surprising when one considers that Marconi was on Signal Hill in the same century.
Question: We can learn from the text that Signal Hill was once used as _ .
Options: (A) a site of communication (B) a weather station (C) a factory to produce weapons (D) a battle field to fight enemies from the outside
Answer:
A
