Article: PALO ALTO, California----"Switching off the television may help prevent children from getting fatter---- even if they do not change their diet or increase the amount they exercise," US researchers said last week. A study of 192 third and fourth graders, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds(0.9kg) less over a one-year period than those who did not change their television diet. "The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity," said Thomas Robinson, a pediatrician at Stanford University. "American children spend an average of more than four hours per day watching television and videos or playing video games, and rates of childhood being very fat have doubled over the past 20 years," Robinson said. In the study, presented this week to the Pediatric Academic Societies' annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third. Children watching fewer hours of television showed a significantly smaller increase in waist size and had less body fat than other students who continued their normal television viewing, even though neither group ate a special diet or took part in any extra exercise. "One explanation for the weight loss could be the children unstuck to the television may simply have been moving around more and burning off calories," Robinson said. "Another reason might be due to eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more," Robinson said. Question: According to the passage, the time American children usually spend on watching TV _ . - is more than four hours a day - is less than four hours a day - doubled in the last twenty years - is more than on any other activities
is more than four hours a day

Read the following article and select the best answer. Article: Beginning in October, more than 13,000 McDonald's restaurants in America will use a new variety of cooking oil. McDonald' s aims to make its French fries and other fried foods healthier. The change will not affect the taste or the number of calories in the food. But by changing the cooking oil, McDonald's says, it hopes to cut by nearly half the amount of _ in French fries and reduce the amount of saturated fats by 16 percent. Scientists believe that trans fatty acids and saturated fats raise cholesterol levels and increase the risk of heart disease. McDonald's new step is important because McDonald's is an industry leader and other fast-food chains and food processors may follow the lead. For McDonald's ,the action comes at a time when Americans are becoming more and more concerned about; obesity and are increasing pressure on food companies to offer healthy and nutritious food to consumers. After three years of study, McDonald's officials say they are _ oil that is lower in saturated fats and trans fatty acids. McDonald's says the change will not cause higher price for consumers. Though there is some change, scientists say that the amount of trans fat in foods at McDonald's and at other fast-food companies is still important. Question: The main idea of the passage is _ . - McDonald's is a pioneer in food products - McDonald's is enlarging its restaurants in the world - fried foods can't keep up with the development of modem society - McDonald's is to use new cooking oil
McDonald's is to use new cooking oil

Q: Read the following article and select the best answer. Article: There is one difference between the sexes on which every expert and study agrees: men are more aggressive than women. It shows up in 2-year-olds. It continues through school days and persists into adulthood. It is even constant across cultures. And there is little doubt that it is rooted in biology. If there's a woman's trait which is the same as men's aggressiveness, it's what social scientists refer to as the result of "education". Feminists have argued that the caring nature of women is not biological in origin, but rather has been forced into women by a society that wanted to keep them in the home. But the signs that it is at least partly inborn are too numerous to ignore. Just as tiny infant girls respond more readily to human faces, female toddlers learn much faster than males how to pick up nonverbal cues from others. And grown women are far more skilful than men at interpreting facial expressions: A recent study by University of Pennsylvania brain researcher Ruben Gur showed that they easily read emotions such as anger, sadness and fear. The only such emotion men could pick up was disgust. What difference do such differences make in the real world? Among other things, women appear to be somewhat less competitive--or at least competitive in different ways--than men. At the Harvard Law School, for instance, female students enter with qualities just as outstanding as those of their male peers. But they don' t qualify for the well-known Law Review in proper numbers, a fact some school officials owe to women' s discomfort in the incredibly competitive atmosphere. Students of management styles have found fewer differences than they expected between men and women who reach leadership positions, perhaps because many successful women deliberately imitate men. But an analysis by Purdue social psychologist Alice Eagly of 166 studies of leadership style did find one difference: Men tend to be more "autocratic"-making decisions on their own--while women tend to consult colleagues more often. Studies of... Question: It can be inferred from the passage that the writer _ . - denies the difference sexes make in real life - is prejudiced against men - discourages women to be competitive - treats sex difference objectively
A: treats sex difference objectively

Read the following article and select the best answer. Article: Almost no young people today know who the cartoon character Oswald the Rabbit is, but they certainly recognize his successor, Bugs Bunny. Oswald, Bugs, and hundreds of other characters were created by Walt Disney, perhaps the most famous cartoonist in history. Born in prefix = st1 /Chicagoin 1901, Walt Disney always wanted to be an artist. After returning from World War I, in which he drove an ambulance, Disney worked as a commercial artist. He enjoyed drawing cartoons more than anything else, and decided to try his hand at a technology that was new at the time, moving pictures. In the 1920's, he produced several films where he made cartoon characters move as if by magic. The technique Disney used was painstaking. He made hundreds or even thousands of repeated drawings of the same character. In each drawing, the character was changed just a bit. A film was taken of the series of drawings, and when it was shown, the characters appeared to move. The process, called animation, is still used today, although computers have made the process much easier. In 1928, Disney created his most famous character, Mortimer Mouse, who we know today as Mickey. The mouse starred in a cartoon called Steamboat Willie, which was unusual because it involved the use of a sound track. Within the next few years, Disney invented many of his other characters. The list of Disney's animation successes is long and memorable. It includes Pinocchio, Dumbo, Bambi, Cinderella, and Peter Pan. Perhaps his most remarkable animated film is Snow White and the Seven Dwarfs. Created in 1937, it was an immediate success. Today, more than fifty years later, it is still one of the most popular films for children. Question: What makes the film Snow White and the Seven Dwarfsso remarkable? - It was a little success when created. - It took more than a year to make it. - It was made at a time when there were no computers. - It has remained popular for more than fifty years.
(A).
