If you want to know how crazy people can be about their pets, you might remember that Helmsley left $12 million to her little Maltese dog when she died last year.

The dog's name is Trouble. And apparendy Trouble is still alive. Of course, I would hang on,too, if someone left me $12 million. Look! Top-shelf dog food, soft pillows everywhere, drivers walking me in nice leafy parks. I would live to be 110 in dog years.

The dog's story is still fresh in my mind the other night when I leave a steak house after a superb meal. Then I notice a woman carrying a small bag out of the door behind me.

Once outside, she walks over to where a man is holding a tiny dog hke it's a baby. The dog looks like a Maltese, too, barking and annoying, with a cute haircut,

And now I am treated to an absolute astonishing sight. Because now the woman reaches into the bag and begins pulling out little pieces of meat, which she puts on a plastic spoon and feeds to the dog.

This is no cheap steak house. It's actually, way out of my league --I'm there only because it's a special occasion. I can tell you this: if I walked out of the place with any leftover steak, it sure wouldn't go to a dog. Not at those prices.

So now the woman is Spoon-feeding the dog and the man is just standing there, holding this dog and looking as if this is the most normal thing in the world. And the dog is calmly chewing these pieces of steak as if he's a little king. And this dog is in no hurry. He's having a great time.

A few minutes go by, and now the dog finishes all of his steak. At this point, I hear the woman say to the man "Think he's still hungry?" And she glances behind her at the restaurant, as if she might go back in there to get more steak for the dog.

Watching all this, I'm afraid I'm going to shout, "Are you out of your mind? Feeding all that pricey steak to that little dog? Did you see what our American life is like today? We're all going to be eating dog food if this keeps up!"

18世纪中叶，曹雪芹的《红楼梦》问世，在中国文学发展史上树起了一座灿烂的艺术丰碑。此后，对《红楼梦》的研究不断展开，逐渐形成了一门专门的学问——红学。阅读材料，回答问题。

材料：《红楼梦》的批评与研究可以分为四个阶段。

第一个阶段是从1754年至1901年。

第二阶段是1902年至1949年，这是现代红学的开端。1917年时任北大校长的蔡元培出版《石头记索隐》，继承了清中期以来对《红楼梦》研究的思路。1921年时任北大教授的胡适发表《红楼梦考证》，观点正好与蔡元培相反，两人发生了激烈的争论。胡适使用“科学”、“实验”等方法考证《红楼梦》，吸引了一大批的追随者，真正形成了一个学术流派，开启了现代红学的研究。

第三阶段自1949年至1978年。1954年，毛 * * 写下了《关于<红楼梦>研究问题的信》，亲自领导和发动了对俞平伯《红楼梦》研究和胡适思想的批判运动，开了建国后将不同学术观点之争同政治斗争联系起来的先河。此后，用阶级斗争分析法研究《红楼梦》成为红学的主流。

第四阶段自1978年至现在，以中共十一届三中全会的召开为标志，《红楼梦》研究与海外红学合流而相呼应，从而进入了一个更加彻底的多元化时代。
