Article: We should feel grateful in our heart when we accept anything others sacrifice for us. However, we often unconsciously do the opposite, which may not be regarded as returning kindness with ingratitude, but have the equal power to harm each other. In particular, the closer the relationship is, the more determined we are. Jennifer, my friend Randy's mother, is already over 70, poor eyesight and weak legs. But due to her character, she chose to live alone in the suburbs. No matter how busily Randy works, he would go there to visit her once or twice every week. That day as soon as he parked his car, Randy smelt the delicious smell of meat coming from her mother's house. His mother said, "Your birthday is coming next week, so I'm preparing pork trotters for you!" Seeing the steaming delicious trotters, he couldn't help complaining, "I don't like these things at all, so fatty." On his way back, he called me, saying that he felt sorry. In fact, he longed to thank his mother and eat up that bowl of trotters. But he felt sorry that it took her too much time and energy. If he didn't stop her strictly, he was afraid the same thing would continue. He would rather not eat trotters any more than have his mother overwork. I understand how he felt exactly. Each of us has done like that. Because of feeling sorry for others' sacrifice, we purposely harden our heart against accepting others' favor and even criticize them severely in order to frighten their goodness away and make them never do that again. This method may work, but it will hurt each other's feelings. It's not wrong logically, but we always neglect another sound deep in our heart: because we're afraid we can't repay them, we're unwilling to shoulder others' goodness. So we reduce its value and refuse it severely. But to destroy others' goodness is also to deny you. Question: Randy telephoned the author to _ . Yes or no, is the answer "express his apology to his mother"?
No

Article: Started in 1636, Harvard University is the oldest of many colleges and universities in the United States. Yale, Princeton, Columbia and Dartmouth were all started before the American Revolution made the thirteen colonies into states. In the early years, these schools were much alike. Only young men attended colleges. All the students studied the same subjects, and everyone learned Latin, Greek and Hebrew. Little was known about science then, and one kind of school could teach everything that was known about the world. When the students graduated, most of them became ministers or teachers. In 1782, Harvard started a medical school for young men who wanted to become doctors. Later, lawyers could receive their training in Harvard's law school. In 1852, Harvard began teaching modern languages, such as French and German, as well as Latin and Greek. Soon it began teaching American history. As knowledge increased, Harvard and other colleges began to teach many new subjects that interested them. Special colleges for women were started. New state universities began to teach such subjects as farming, engineering and business. Today, there are many different kinds of colleges and universities. Most of them are divided into smaller schools that deal with special fields of learning. There is so much to learn that one kind of school cannot offer it all. Question: As knowledge increased, colleges began to teach _ . Yes or no, is the answer "many new subjects"?
No

Q: Article: Drawings of human colonies on other planets often picture the entire community under a glass or plastic bubble. The bubble is intended to create an atmosphere with adequate oxygen and other essential elements. But similar bubble-like structures have also been constructed on earth. One of the most famous, and controversial, is a site in the Arizona desert. Biosphere 2, as it is called, was built not far from Tucson in 1984 and is now run by Columbia University. This huge(7,200,000-cubic-foot)glass and steel construction contains several separate ecosystems, including a desert, a rain forest, and a 900,000-gallon "ocean." The climatic conditions-humidity, temperature, air quality-are regulated by sensors and can be adjusted as needed or desired. For example, a rainstorm can be created to increase the humidity. The adjustable features of Biosphere 2 make it an ideal location to perform experiments to help determine the effects of such climatic changes as global warming. The current conditions at Biosphere 2 are vastly different from those in 1993, when eight people who had moved into the environment with great fanfare two years earlier moved out in failure. Though promising to be self-sufficient , these "colonists" had so much trouble regulating the environment that they reportedly had food smuggled into them. Oxygen levels became dangerously low; most plants and animals died. In taking over the unsuccessful site, Columbia hopes to erase its notorious past by focusing on small research projects that gradually answer some of Biosphere 1's -- that is, Earth's most basic environment questions. Question: The writer helps you understand what Biosphere 2 is like by _ . Yes or no, is the answer "describing its appearance and conditions"?
A: Yes

Question: Article: Thid is a true story of a mother's sacrifice in an earthquake. When the rescuer reached the ruins of a young man's house, they saw her dead body through the cracks.
