The problem with history is simple. There is too much of it, And more of it comes along every day. We need something that will cut the past down to size. We want heroes and heroines that a modern person can identify with. That is where Hollywood comes in.
Film makers have often based their work on historical events. Why go to the trouble of writing a brand new story when so many exciting things have happened in the pasty People will often already know the story, That leaves the director free to thrill us with details of what life as like in imperial China or ancient Rome.
Most historians dislike this attitude. They see history as a complex thing, influenced by great political and economic forces. Film audiences are not very interested in this. They want kings and queens. They pay their money to see fancy clothes and a good fight. And this is what the film industry tries to give them.
Sometimes this approach can cause trouble. The film Titanic was a success around the world. In one of the film's most dramatic moments, a member of the ship's crew begins shooting into the crowd trying to get into the lifeboats as the ship sinks. When the film was released, the real life sailor's surviving relatives protested. They pointed out that this was not what had actually happened The film makers made a public apology. But everyone who has seen the film remembers the sight of the man shooting into the crowd.
Defenders of "Hollywood history" say that most of the time the film makers get the facts right. The action is based on real events and the clothes are accurate. People talk in the way that they would have done in the past even if they do it with a modern American accent. For many people, a historical film will be the closest they come to discovering the past.
It is still possible to find mistakes. Millions have been spent on putting together a replica of ancient Rome. The costumes are right and the atmosphere is perfect. Yet if you look very closely, a plane can be seen passing through the sky above.
Some film makers say that history needs to be simplified if it is to be filmed. The film maker's job is to make viewers interested. If they want to know more, they can do their own research.
The difference between film history and real history is the difference between the facts and the truth. We can watch a "costume drama" and know that all the materials used are probably accurate. But if we want to find out the whole story, we have to do it ourselves. We have to go back to the books.
The main point of the passage is______.
A．that films based on past events are often big hits
B．how much we can trust the Hollywood version of history
C．that we should read books rather than see films to know the history
D．why film audiences are interested in film history rather than real history

One of the qualities that most people admire in others is the willingness to admit one's mistakes. (79) It is extremely hard some times to say a simple thing like "I was wrong about that," and it is even harder to say, "I was wrong, and you were right about that."
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.

You might think that borrowing a match upon the street is a simple thing. But any man who has ever tried it will assure you that it is not, and will be prepared to swear on oath to the truth of my experience of the other evening.
I was standing on the corner of the street with a cigar that I wanted to light. I had no match. I waited till a decent, ordinary man came along. Then I said:
"Excuse me, sir, but could you oblige me with the loan of a match？"
"A match？" he said, "why, certainly." Then he unbuttoned his overcoat and put his hand in the pocket of his waistcoat. "I know I have one," he went on, "and I'd almost swear it's in the bottom pocket — or, hold on, though, I guess it may be in the top — just wait till I put these parcels down on the sidewalk."
"Oh, don't trouble," I said. "It's really of no consequence."
"Oh, it's no trouble, I'll have it in a minute; I know there must be one in here somewhere"—he was digging his fingers into his pockets as he spoke — "but you see this isn't the waistcoat that I generally…"
I saw that the man was getting excited about it. "Well, never mind," I protested; "if that isn't the waistcoat that you generally — why, it doesn't matter."
"Hold on, now, hold on!" the man said. "I've got one of the cursed things in here somewhere. I guess it must be in with my watch. No, it's not there either. Wait till I try my coat. If that damned tailor only knew enough to make a pocket so that a man could get at it!"
He was getting pretty well worked up now. He had thrown down his walking-stick and was searching his pockets with his teeth set. "It's that cursed young boy of mine," he exasperated; "this comes of his fooling in my pockets. By God! perhaps I won't warm him up when I get home. Say, I'll bet that it's in my hippocket. You just hold up the tail of my overcoat a second till I…"
"No, no," I protested again,"please don't take all this trouble, it really doesn't matter. I'm sure you needn't take off your overcoat, and oh, pray don't throw away your letters and things in the snow like that, and tear out your pockets by the roots! Please, please don't trample over your overcoat and put your feet through the parcels. I do hate to hear you swearing at your little boy, with that peculiar grumble in your voice. Don't — please don't tear your clothes so savagely."
Suddenly the man gave a grunt of joy, and drew his hand up from inside the lining of his coat.
"I've got it," he cried. "Here you are!" Then he brought it out under the light.
It was a toothpick.
Yielding to the impulse of the moment I pushed him under the wheels of a trolley-car and ran.
