第三节：阅读理解（共25小题; 每小题2分, 满分50分）

It was 3:12 a. m. when nine-year-old Glenn Kreamer awoke to the smell of burning. Except for the crackling（爆裂声）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, collapsed on the lawn (草坪).

The nine-year-old raced back into the house and upstairs to his mother’s room. He found it impossible to woke 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 remained 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 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.

2000年，我国彩电行业出现全行业亏损。康佳，长虹等彩电行业巨头异口同声地说：是行业内恶性价格战的结果。康佳每次价格战出手都特别狠，一下子就将其34英寸彩电的价格降到3000元以下，令业界大跌眼镜。但是，康佳总经理说：康佳不愿意打价格战，但康佳又不得不打。为了既得的市场份额，为了流动资金的周转和出手价值跌得越来越多的存货又不得不打。长虹深受价格之害，但又是价格战的发动者和加油者。仅几天前，长虹，TCL等八大品牌企业刚达成共识：理性地对待价格战，建立对话机制，摆脱价格战的纠缠。目前国内彩电业只有在竞争中合作，在合作中竞争，才能推动行业发展，才能把蛋糕做大。但是事隔几天，长虹又把它的背投彩电的价格降到万元之下了。其新闻发言人说：打价格战是很无奈很艰难的事情，但是在彩电业缺乏退出机制的情况下企业只能靠价格战苦撑。乐华彩电的老总说：我们是在流着血打价格战。根据以上资料，请你回答下列问题：

如果你是我国彩电行业内某个品牌企业的董事长（或总经理），面对行业内的恶性价格战，你的策略是什么？
