Article: A recent survey in the United States showed that the average family spent more money on its pets than on its children. Although rather shocking, it should not surprise anyone who has seen the doggy parlors where loved pets rest. Are Americans unique in treating their little friends in this way? No, the English, too, pay more attention to their pets. This can clearly be seen when we look at pet foods, which often contain more vitamins than human food. They certainly cost much. Last year the British public spent two hundred million pounds on pet food alone, to say nothing of veterinary bills or animal furniture. It is difficult not to feel angry about this when considering what the same amount could do for victims of starvation and poverty, so it is not unusual for me _ when I read an old man left all his money to his dog instead of his children. There are a variety of reasons why I find pets-raising alarming. They cause physical problems. An example of this is New York where they have great difficulty getting rid of the mess that dogs leave on the streets. Many people find this funny, but in a number of large cities it is a major problem. Animals can cause disease, too. It is the threat of rabies -- a disease with no known cure. Another problem is the carelessness of pet owners. Most little children want a dog or a cat, and they continually push their mothers and fathers until they get one. It is only when the "sweet little thing" has been brought home that the parents realize how much time and money must be spent on "Rover" or "Bonzo". Then they just abandon it. As a result, they are allowed to run free. English farmers lose hundreds of sheep a year, killed by someone's pet and you must have read of children being hurt by some pets of their own. Lastly, I would only suggest that we have got our priorities wrong and that something should be done about it. In my view, it's time we stopped being sentimental about pets. I can see no reason why we should get upset when animals are cut up for medical experiments.... Question: According to the author, in which field can animals be most useful? Yes or no, is the answer "Medicine."?
No

Article: What will power your house in the future? Nuclear, wind, or solar power? According to scientists at the Massachusetts Institute of Technology (MIT) in the US, it might be leaves -- but artificial ones. Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis . Now researchers have found a way to imitate this seemingly simple process. The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts . Similar to natural leaves, it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell, which uses those two materials to produce electricity, located either on top of a house or beside the house. Though the leaf is only about the shape of a poker card, scientists claimed that it is promising to be an inexpensive source of electricity in developing countries. "One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology," said Nocera at a conference of the American Chemical Society. The artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf, by contrast, is made of cheap materials, easy to use and highly stable. In laboratory studies, Nocera showed that an artificial leaf prototype could operate continuously for at least 45 hours without a drop in activity. The wonderful improvements come from Nocera's recent discovery of several powerful, new and inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now, the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides, the device can run in whatever water is available; that is, it doesn't need pure water. This is important for some countries that don't have access to pure water. With the goal to "make... Question: The main idea of this passage is about _ . Yes or no, is the answer "an invention copying photosynthesis"?

No

Ques: Article: After a while, Tommy's parents, who had recently separated, would arrive for a meeting on his failing schoolwork and bad behavior. Neither parent knew that I had called the other. Tommy, an only child, had always been a happy, cooperative and top student. How could I make his father and mother believe that his recent failing grades meant a broken-hearted child's reaction to his parents' separation and divorce ? Tommy's mother entered and took one of the chairs. Soon the father arrived. Good! At least they were enough to be here in time. They ignored each other. As I gave a detailed introduction of Tommy's behavior and schoolwork, I waited for the right words to bring these two together to help them see what they were doing to their son. But somehow the words wouldn't come. Perhaps if they saw one of his dirty, carelessly done papers? I found a sheet in the back of his desk. Writing covered both sides: not the exercises, but a single sentence scribbled over and over. Silently I gave it to Tommy's mother. She read it and then handed it to her husband. Then his face softened. At last he folded the paper carefully, placed it in his pocket, and reached for his wife's hand. She wiped the tears from her eyes and smiled up at him. He helped with her coat and they left together. In his own way God had given me the words to reunite that family. He had guided me to the sheet of yellow copy paper covered with the pain outpouring of a small boy's troubled heart. The words are "Dear Mom... Dear Daddy... I love..." Question: The author called Tommy's parents in order to _ . Yes or no, is the answer "help them realize their influence on Tommy"?
Ans: No

Article: "To educate a girl is to educate a thousand people," says Maimouna Samake, a mother of six children(including five girls). "If you put one seed in the ground and rain comes, it will grow to produce many seeds." Samake, one of 2,000 residents, lives in a small village, Sounkala, in one of the world's poorest countries. Now she has a chance to see this wish come true thanks to build On, an American non-profit organization that is building a school in her community. For 17 years, build On has been sending American high school students overseas to create schools in places where literacy and formal education are usually out of reach. The organization has built about 300 schools in Mali, Malawi, Nepal, Senegal, Nicaragua and Haiti. Its goal is to get young Americans in mostly urban areas to get involved in education. At the same time it can bring literacy to children and adults in poor villages in the developing world. Sounkala's school only has about 70 children; mud floors, poor lighting, few desks and an absence of books mean that the school is not the most ideal learning environment. Therefore they certainly could use build On's help. Samake hasn't been to school, but she wants a better future for her five daughters, including Ramatou, 12, and Mariam, 10. "When a woman attends school, she will teach what she learns to her children," said Ramatou, who wants to become a doctor. "She will also know how to take better care of her family." Build On tries to build schools for grades one to three. If things go well over those three years, they return to help build another school for grades four to six, and then set up evening adult literacy classes. Ramatou and Mariam will not learn inside the walls of build On school since they are already in the sixth grade, but Samake hopes that they will be able to attend evening classes to continue learning. Question: Which of the following aspects of build On is NOT mentioned in the text? Yes or no, is the answer "Its sources of money."?
Yes
