It was 3:21 a.m. when nine-year-old Glenn Kreamer awoke to the smell of burning. Except for the cracking (爆烈声) of flames somewhere below there was not a sound in the two-storey house at Baldwin Long Island.
With his father away on night duty at a local factory, Glenn was worried about the safety of his mother, his sister Karen, 14 and his 12-year-old brother Todd. He ran downstairs through the smoke-filled house to push and pull at Karen and Todd until they sat up. Then he helped each one through the house to the safety of the garden. There, his sister and brother, taking short and quick breaths and coughing, fell down onto the lawn.
The nine-year-old boy raced back into the house and upstairs to his mother’s room. He found it impossible to wake her up. Mrs. Kreamer, a victim of the smoke, was unconscious, and there was nobody to help Glenn carry her to the garden. But the boy stayed calm and, as a fireman said later, "acted with all the self-control of a trained adult."
On the bedroom telephone, luckily still working, Glenn called his father and, leaving Mr. Kreamer to telephone the fire brigade and ambulance service, got on with the task of saving his mother.
First he filled a bucket with water from the bathroom and threw water over his mother and her bed. Then, with a wet cloth around his head he went back to the garden.
He could hear the fire engine coming up, but how would the firemen find his mother in the smoke-filled house where flames had almost swallowed up the ground floor?
Grasping firmly a ball of string (线) from the garage, Glenn raced back into the house and dashed upstairs to his mother’s room. Tying one end of the string to her hand, he ran back, laying out the string as he went, through the hall and back out into the garden.
Minutes later he was telling fire chief John Coughlan, "The string will lead you to mother." Mrs. Kreamer was carried to safety as the flames were breaking through her bedroom floor.
1.Why did Glenn run downstairs first?
A.He wanted to find out what was happening.
B.He was worried about his mother’s safety.
C.He wanted to save his sister and brother.
D.He went to see if his father had come back from work.
2.Who called the fire brigade and ambulance service?
A.Glenn. B.Glenn’s father.
C.Glenn’s sister. D.Glenn’s neighbor.
3.Which of the following can replace “unconscious” in Paragraph 3?
A.unfortunate B.confuse
C.terrified D.senseless
4.Glenn saved his family because ______.
A.his father had taught him to do so on the phone
B.he had learned something about first aid

Celebrity (名人) has become one of the most important representatives of popular culture. Fans used to be crazy about a specific film, but now the public tends to base its consumption (消费) on the interest of celebrity related to any given product. Besides, fashion magazines have almost abandoned the practice of putting models on the cover because they don’t sell nearly as well as famous faces. As a result, celebrities have realized their unbelievably powerful market potential (潜力), moving from advertising for others’ products to developing their own.
Celebrity clothing lines aren’t a completely new phenomenon (现象), but in the past they were typically aimed at the ordinary consumers, and limited to a few TV actresses. Today they’re started by first-class stars whose products enjoy equal fame with some world top brands. The most successful start-ups have been those by celebrities with specific personal style. As celebrities become more and more experienced at the market, they expand their production scale (规模) rapidly, covering almost all the products of daily life.
However, for every success story, there’s a related warning tale of a celebrity who overvalued his consumer attraction. No matter how famous the product’s origin is, if it fails to impress consumers with its own qualities it begins to look like an exercise in self-promotional marketing. And once the attention dies down, consumer interest might decrease, loyalty returning to tried-and-true labels.
Today, celebrities face even more serious embarrassment. The pop-cultural circle might be bigger than ever but its rate of turnover has speeded up as well. Each misstep threatens to reduce a celebrity’s shelf life, and the same newspaper or magazine that once brought him fame (名声) has no problem picking him to pieces when the opportunity appears. Still, the ego’s (自我的) potential for expansion is limitless. Having already achieved great wealth and public recognition, many celebrities see fashion as the next frontier to be conquered. As the saying goes, success and failure always go hand in hand. Their success as designers might last only a short time, but fashion-like celebrity-has always been temporary.

One of the best things you can do for your health is to drop a few pounds. Or maybe more than a few pounds.
Being overweight increases your danger of heart disease, high blood pressure, cancer, and the list seems almost endless. You'd better find several simple things you can do on a daily basis — such as making rules of eating more vegetables and less fat and getting more physical activities.
After breakfast, make water your primary drink. At breakfast, go ahead and drink orange juice. But throughout the rest of the day, focus on water instead of juice or soda. The average American consumes (消耗) an extra 245 calories a day from soft drinks. That's nearly 90,000 calories a year — or 25 pounds! An research shows that neither the calories nor sugary drinks give you a sense of fullness the way that food does.
People take only 2,000 to 3,000 steps a day. Adding 2,000 steps will help you keep your present weight and stop gaining weight. Adding more than that will help you lose weight.
Eat five or six small meals or snacks a day instead of three large meals. A 1999 South African study found that when men ate parts of their morning meal at intervals over five hours, they consumed almost 20 percent fewer calories at lunch than when they ate a single breakfast.
