Read the article and select the best answer. Article: The failed Skylab will come screaming home to the earth in disappointment sometime next month, but we don't know where it will fall. That precise information is beyond even the calculations of scientist and their computers. The best they can tell us is that the space station, weighting 77 tons and as high as a 12-story building, will break into hundreds of pieces that will be scattered across a track 100 miles wide and 4,000miles long. We are again exposed to one of those unexpected adventures, or misadventures, of science that attract our attention from the boring routines of daily existence and encourages us to think a lot about man's future. What worries Richard Smith, the Skylab's director, is the "big pieces" that will come through the atmosphere. Two lumps, weighing 2 tons each, and ten, weighing at least 1,000 pounds each, will come in at a speed of hundred of miles an hour, and if they crash on land they will dig holes up to 100 feet deep. What worries us, with our lack of scientific knowledge and our quick imagination, is both the big and little pieces, although project officials say there is a very small chance that anyone will be injured by them. That's good to know, but it doesn't remove the doubt of the millions who still remember the nuclear accident at Three Mile Island. That accident took place in 1979 in spite of what scientists had assured(...) us as to the safety of the nuclear reactor . Question: The writer expresses his _ . Options: A: interest in the failure of the Skylab B: willingness to give his advice C: worry about the misadventure of science D: eagerness to see more new scientific discoveries

Read the article and select the best answer. Article: Oceanography has been defined as "The application of all sciences to the study of the sea". Before the nineteenth century scientists with an interest in the sea were few and far between. Certainly Newton considered some theoretical aspects of it in his writings, but he was reluctant to go to sea to further his work. For most people the sea was remote, and with the exception of early intercontinental travelers or others who earned a living from the sea, there was little reason to ask many questions about it, let alone to ask what lay beneath the surface. The first time that the question "What is at the bottom of the oceans?" had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed. The engineer had to know the depth profile of the route to estimate the length of cable that had to be manufactured. It was to Maury of the US Navy that the Atlantic Telegraph Company turned, in l853, for information on this matter. In the 1840s, Maury had been responsible for encouraging voyages during which soundings were taken to investigate the depths of the North Atlantic and Pacific Oceans. Later, some of his findings aroused much popular interest in his book The Physical Geography of the Sea. The cable was laid, but not until 1866 was the connection made permanent and reliable. At the early attempts, the cable failed and when it was taken out for repairs it was found to be covered in living growths, a fact which defied contemporary scientific opinion that there was no life in the deeper parts of the sea. Within a few years oceanography was under way. In 1872 Thomson led a scientific expedition, which lasted for four years and brought home thousands of samples from the sea. Their classification and analysis occupied scientists for years and led to a five-volume report, the last volume being published in l895. Question: The proposal to lay a telegraph cable from Europe to America made oceanographic studies take on _ . Options: A: a business aspect B: a military aspect C: an academic aspect D: an international aspect

Read the article and select the best answer. Article: Mother's Day is coming up. Maybe your gift is wrapped and your dinner plans booked for mom, step-mom, grandmother - whoever the person is who fed, cared for, taught and loved you. But there are other people who said their most special Mother's Day memories rarely dealt with beautifully wrapped objects, but rather, the ways people showed they cared. Mother's Day 2012 was the last one Jannet Walsh was able to celebrate with her mother, Margaret, who had a stroke in 2009. In her last few years, Walsh always shot photos and videos of their visits together, and with Walsh's West Highland White Terrier, Andrew. "My mother had a dog just like him, so I would tell her it was her dog, and she would hold onto his leash, even in bed up to the last few weeks before she passed away," Walsh said. As Mother's Day approached, Walsh wanted a way to remember her mother and "best friend". She decided to build the memories she captured during those last few years into a video memorial - images of her mother with Andrew or quiet moments at her gravesite. "I thought it good to tell the story with few words, just show my mother as she was - happy, and loved till the end," Walsh said. Mother's Day was not a light-hearted subject for Wendy Bowers in the past. Her mom had walked out when she was 18, and Bowers had tried for years to become pregnant without success. She had almost convinced herself she wasn't meant to be a parent. But three years after she gave up on having a baby, Bowers discovered that she was pregnant. Six weeks earlier than expected, little Nathan arrived. That first year, Nathan, only 10 months old, was sick with a stomach bug. Bowers said she spent the day holding him between loads of laundry. "I would not have been anywhere else in the world that day," she said. "I wouldn't trade that first Mother's Day for anything, and I'm pretty sure Mother's Day will always be a reminder to me of just how lucky I am to even be a mom." Question: What is the text mainly about? Options: A: Painful memories of Mother's Day. B: Plans for Mother's Day. C: Tips for a special Mother's Day. D: Special ideas for Mother's Day.
