听力原文： The king has taken a knock. Nokla warned that the U. S. slowdown is now extending to other economies, and said that is cutting into demand for Nokia' s handsets, and for its growing mobile infrastructure business.
In April, a more optimistic Nokia said it was on course for a 20 percent sales growth this quarter. That forecast has been cut in half. Tuesday' s warning knocked a whopping $31 billion off Nokia' s market cap. Nokia joins rivals Motorola and Ericsson in warning about sales. The rate of new phone purchases has slowed dramatically in Europe, with customers reluctant to trade up to new handsets.
What' s the effect of the US slowdown？
A．Cutting into demand for Nokia' s handsets.
B．Promote other economies.
C．Many firms break down.
D．Many handsets don' t sell.

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

James Marshall, the President of the United States, was on his way back home from Moscow aboard the presidential jet, Air Force One. Six Russian journalists were also aboard, pretending to interview the President. Seizing the chance, the Russians hijacked (seized control of) the plane. It seemed that the President himself escaped in a special emergency pod (救生仓) . Ivan Korshunov, the leader of the terrorists (恐怖主义者) , get in touch with the White House. He told Vice President Kathryn Bemnett that unless his leader, the extreme nationalist General Radek was set free form. a Moscow prison, he would kill the passengers one by one. He made it clear that he had President’s wife and child in hand.
Marshall was actually in a hiding-place. Using his mobile (移动的) phone, he got himself connected with the White House. He told the Vice President not to talk with the terrorists in spite :of the killing. At the same time he killed one of the terrorists and at last helped most of the hostages (人质) to escape using parachutes (something for making people fall slowly and safely from a plane). However, Ivan was still holding his wife and daughter. Rather than see either killed , Moscow to set General Radek free. He and Ivan fought it out and at last Ivan was killed.

The biggest danger facing the global airline industry is not the effects of terrorism, war, SARS and economic downturn. It is that these blows, which have helped ground three national flag carriers and force two American airlines into Chapter 11 bankruptcy, will divert attention from the inherent weaknesses of aviation, which they have worsened. As in the crisis that attended the first Gulf war, many airlines hope that traffic will soon bounce back, and a few terrible years will be followed by fuller planes, happier passengers and a return to profitability. Yet the industry's problems are deeper—and older—than the pain of the past two years implies.
As the 100th anniversary of the first powered flight approaches in December, the industry it launched is still remarkably primitive. The car industry, created not long after the Wright Brothers made history, is now a global industry dominated by a dozen firms, at least half of which make good profits. Yet commercial aviation consists of 267 international carriers and another 500-plus domestic ones. The world's biggest carrier, American Airlines, has barely 7% of the global market, whereas the world's biggest carmaker, General Motors, has (with its associated firms) about a quarter of the world's automobile market.
Aviation has been incompletely deregulated, and in only two markets: America and Europe. Everywhere else deals between governments direction who flies under what roles. These aim to preserve state-owned national flag-carriers, run for prestige rather than profit. And numerous restrictions on foreign ownership make cross-border airline mergers impossible.
In America, the big network carriers face barriers to exit, which have kept their route networks too large. Trade unions resisting job cuts and Congressmen opposing route closures in their territory conspire to block change. In Europe, liberalization is limited by bilateral deals that prevent, for instance, British Airways (BA) flying to America from Frankfurt or Pads, or Lufthansa offering transatlantic flights from London's Heathrow. To use the car industry analogy, it is as if only Renaults were allowed to drive on French motorways.
In airlines, the optimists are those who think that things are now so bad that the industry has no option but to evolve. Frederick Reid, president of Delta Airlines, said earlier this year that events since the 911 attacks are the equivalent of a meteor strike, changing the climate, creating a sort of nuclear winter and leading to a "compressed evolutionary cycle". So how, looking on the bright side, might the industry look after five years of accelerated development？
According to the author, the deeper problems of aviation industry ______.
A．are the effects of various disasters
B．are actually not fully recognized
C．are attracting a lot of attention
D．are not the real cause of airlines' bankruptcy

I have certainly seen lots of changes in my lifetime! I look around my home and see "mod cons" that I could never have dreamed of 50 or 60 years ago. I spent the early part of childhood in a cottage without running water or electricity and yet these days, I feel paralyzed if there is a power cut for even just an hour or two! So, I have changed too. Things that I couldn't even imagine in the past now seem quite normal.
Businessmen can travel from London to New York in three hours and lots of people exceed the seventy-mile-per-hour speed limit on motorways. A person of 75 is not old these days. A serious illness does not mean certain death because there have been so many advances in medical science. We no longer need to be afraid of contracting diseases like polio or smallpox. I can speak to my son in Australia from my own sitting room here in Manchester, watch athletes running a race on the other side of the world without moving from my own home and I can even do my shopping while I sit here in an armchair. I never need to worry about food going bad in the warm weather and, at the flick of a switch, I can have a hot meal in a couple of minutes. So, it seems, the quality of life has greatly improved since my own childhood.
I'm not convinced, however, that people are happier today than they were 50 years ago. We are certainly materially better off than we were but most people still seem to be weighed down by problems. My daughter and her family are a good illustration. They have a spacious, comfortable home with every labor-saving device you can think of. There's a washing machine, a clothes dryer, a food processor, a vacuum cleaner and all sorts of other household items which are designed to save time but it seems to me that my daughter and her husband just spend all that "saved" time working! They never relax and are always complaining of being tired and "stressed".
What is the passage mainly about？
A．How life has improved.
B．How life has become worse.
C．A comparison of life now and that in the past.
D．Memory of life in the past.
