单选题 One day, a poor boy who was selling goods from door to door to pay his way through school found he had only one thin dime left, and he was hungry. He decided he would ask for a meal at the next house. However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, 'How much do I owe you?' 'You don't owe me anything,' she replied. He said, 'Then I thank you from my heart.' Years later that young woman became critically ill. The local doctors sent her to the big city, where they called in specialists to study her rare disease. Dr. Howard Kelly was called in for the consultation. When he heard the name of the town she came from, he rose immediately and went to her room. Dressed in his doctor's gown he went in to see her. He recognized her at once. He went back to the consultation room determined to do his best to save her life. From that day he gave special attention to the case. After a long struggle, the battle was won. Dr. Kelly requested the business office to pass the final bill to him for approval. He looked at it and then wrote something on the edge. The bill was sent to her room. She feared to open it, for she was sure it would take the rest of her life to pay for it all. Finally she looked, and something caught her attention on the side of the bill. She read these words: 'Paid in full with one glass of milk.'

单选题 You ask how to start a business? Here is an example. David Dawson, a serious mountain climber, was dissatisfied with soft iron pitons (锥锤), the only ones he was able to buy. They lasted just one or two climbs, and Dawson wanted to replace them with 'chrome-molys' (铬率合金), which were harder, stronger and longer-lasting. Some climbers made them for limited distribution among friends, but they were not commercially available. So Dawson started Dawson Equipment Ltd. , a purveyor (承办商) of climbing equipment, as a one-man enterprise in Burbank, California, in 1958. He had no plan, no management experience and no advertising. He worked in a shed using a hand forge purchased with $ 800 of capital borrowed from his mother. What Dawson did have was a knowledge of the kind of equipment that he needed in his own climbs, and a sense that serious climbers would follow his lead. Currently Dawson Equipment is thriving and produces over 200 products. Business opportunities are mere than ample today for the simple reason that many consumers are dissatisfied. Dawson's business started from his being a customer not liking what he bought. I suspect that your business will begin that way too. You know what you want to replace, improve or change. So begin where the tool breaks, the service slips or the shoe pinches.

单选题 Dear David, I'm glad you would like to share your feelings with me. It's hardly surprising that your feelings of not being 'grown up' have come on strongly at this point in your life, just before you're about to become a father. I think nearly every sensitive about-to-be-parent must have these occasional feelings of self-doubt and inadequacy (不适) before the birth and it would be most unusual if you didn't share them. It's difficult, honestly, to feel grown-up unless you have something less grown-up to relate to. The boss with a hen-pecking wife may feel like a seven-year-old when he's at home. But as he walks through the office door, and knows he's going to be surrounded by staff looking to him for advice, he grows into a fully mature (成熟的) man. And I think it's a mistake to imagine that we all feel, as we age, a kind of progression of states, from the baby to the adult. Most people feel, on Tuesday, about three years old, and on Wednesday, around 80. There's a common remark that 'all men are little boys', but it's not true. It's more true that men often behave like little boys. But nearly all people, at some moments in their lives, are able to be great mature. Once your baby arrives, you'll soon feel less childlike, or rather, less often. When your child tries to put its fingers into the electric plug, the adult in you will rise up to prevent it. You'll see you have very little in common with a needy child, particularly if it's looking to you for comfort and support. Comfort yourself, David. Hope my advice will be helpful and good luck to you and your little one. Sincerely Yours, Miss Advice

单选题 How many things can you see in the night sky? A lot! On a clear night you might see the Moon, some planets, and thousands of sparkling stars. You can see even more with a telescope. But scientists believe there are some things in the sky that we will never see. We won't see them with the biggest telescope in the world, on the clearest night of the year. That's because they're invisible. They're the mysterious dead stars called black holes. As a star's gases burn, they give off light and heat. But when the gas runs out, the star stops burning and begins to die. As the star cools, the outer layers of the star pull in toward the center. The star squashes (挤压) into a smaller and smaller ball. If the star was very small, the star ends up as a cold, dark ball called a black dwarf. If the star was very big, it keeps squashing inward until it's packed together tighter than anything in the universe. Imagine if the Earth were crushed until it was the size of a tiny marble. That's how tightly this dead star, a black hole, is packed. What pulls the star in toward its center with such power? It's the same force that pulls you down when you jump—the force called gravity. A black hole is so tightly packed that its gravity sucks in everything—even light. The light from a black hole can never come back to your eyes. That's why you see nothing but blackness. So remember: Scattered in the silent darkness are black holes—the great mystery of space.
