In an article on the new manners, Ms. Holmes says that a perfectly able woman no longer has to act helplessly in public as if she were a model. For example, she doesn't need help getting in and out of cars. "Women get in and out of cars twenty times a day with babies and dogs. Surely they can get out by themselves at night just as easily." She also says there is no reason why a man should walk on the outside of a woman on the sidewalk. "Historically, the man walked on the inside so he caught the garbage thrown out of a window. Today a man is supposed to walk on the outside. A man should walk where he wants to. So should a woman. If, out of love and respect, he actually wants to take the blows, he should walk on the inside--- because that's where attackers are all hiding these days." As far as manners are concerned, I suppose I have always been a supporter of women's liberation. Over the years, out of a sense of respect, I imagine, I have refused to trouble women with outdated courtesies. It is usually easier to follow rules of social behaviour than to depend on one's own taste. But rules may be safely broken, of course, by those of us with the gift of natural grace. For example, when a man and woman are led to their table in a restaurant and the waiter pulls out a chair, the woman is expected to sit in the chair. That is according to Ms. Ann Clark. I have always done it the other way, according to my wife. It came up only the other night. I followed the hostess to the table, and when she pulled the chair out I sat on it, quite naturally, since it happened to be the chair I wanted to sit in. I had the best view of the boats. "Well," my wife said, when the hostess had gone, "you did it again." "Did what？" I asked, utterly confused. "Took the chair." Actually, since I'd walked through the restaurant ahead of my wife, it would have been awkward, I should think, not to have taken the chair. I had got there first, after all. Also, it has always been my custom to get in a car first, and let the woman get in by herself. This is a courtesy I insist on as the stronger sex, out of love and respect. In times like these, there might be attackers hidden about. It would be unsuitable to put a woman in a car and then shut the door on her, leaving her at the mercy of some bad fellow who might be hiding in the back seat. It can be concluded from the passage that ______. A．men should walk on the inside of a sidewalk B．women are becoming more capable than before C．in women's liberation men are also liberated D．it's safe to break rules of social behaviour

I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a grocery store in the neighborhood where I grew up, and he asked me if I remembered the egg cartons. Then he related an incident and I began to remember vaguely the incident he was de scribing. I was about eight years old at the time, and I had gone into the store with my mother to do the weekly grocery shopping. On that particular clay, I must have found my way to the dairy food department where the incident tool place. (80) There must have been a special sale on eggs that day be cause there was an impressive display of eggs in dozen and half-dozen cartons. The cartons were stacked three or four feet high. I must have stopped in front of a display to admire the stacks. Just then a woman came by pushing her grocery cart and knocked off the stacks of cartons. For some reason, I decided it was up to me to put the display back together; so I went to work. The manager heard the noise and came rushing over to see what had happened. When he appeared, I was on my knees inspecting some of the cartons to see if any of the eggs were broken, but to him it looked as though I was culprit(罪犯). He severely scolded me and wanted me to pay for any broken eggs. I protested my innocence and tried to explain, but it did no good. Even though I quickly forgot all about the incident, apparently the manager did not. How old was the author when he wrote this article？ A．About 8. B．About 18. C．About 23. D．About 15.

There are several steps that can be taken, of which the chief one is to demand of all the organizations that exist with the declared objectives of safeguarding the interests of animals that they should declare clearly where they stand on violence towards people.
