"I ask you to drink to his health as a young man full of the spirit of adventure who has lit up the world with a flash of courage. "With these words, the British Minister of Air turned and raised his glass to the young man who sat beside him-a young man who, only a month before, was completely unknown. Yet on that summer day in 1927 his name was on the world's lips-Charles Lindbergh, the first man to fly the Atlantic alone.He had been an air mail pilot, flying back and forth between Chicago and the city of St. Louis. Determined to win the $5, 000 prize offered by a fellow American for the first flight form. New York to Paris, Lindbergh had persuaded a group of St. Louis businessmen to finance the building of a special plane for him.The news that Lindbergh intended to fly the Atlantic alone was received with disbelief. The plane would never fly, people said. It would run out of fuel. It had only a single engine. Lloyds of London refused to insure the flight. Men called Lindbergh the "flying fool".But on May 20th, 1927, just after ten to eight in the morning, Lindbergh's "Spirit of St. Louis", heavily laden with fuel, struggled into the air from a New York airfield. For several hours the weight of the petrol prevented the young pilot from flying more than a few feet above the wave-tops. Night came and thick fog covered up the stars. Lindbergh flew steadily on, hoping that his course was the right one. He struggled to keep awake, checking the fuel all the time to keep his mind active. Throughout the next day the "Spirit of St. Louis" flew on over the seemingly limitless sea. Then a fishing boat appeared, and, an hour later, land. It was Ireland. Lindbergh set a compass course for Paris.By ten o'clock the lights of France's capital were shining beneath him. Tired, unshaved, suddenly hungry, the "flying fool" came down to Le Bourget airport, and landed in front of a huge crowd of wildly cheering people. After 34 hours of continuous piloting, the flight of 3, 600 miles was over.1. The British Minister of Air _____.A. praised Lindbergh for his intelligenceB. encouraged Lindbergh to be more adventurousC. congratulated Lindbergh for his braveryD. warned Lindbergh not to fly alone2. "… his name was on the world's lips"means _____.A. "Everybody was drinking to his health"B. "Everybody was jumping about because of him"C. "He became suddenly unpopular"D. "Everybody was talking about him"3. A group of St. Louis businessmen had been persuaded to _____ the building of a special plane.A. arrangeB. organizeC. stopD. pay for4. Which of the following is true? _____A. Nobody at all believed that it was foolish for anybody to try to fly the Atlantic.B. Everybody knew that Lindbergh was very brave and adventurous.C. People didn't believe that Lindbergh really meant to fly the Atlantic alone.D. Everybody believed that it was foolish for anybody to try to fly the Atlantic at all.5. The "Spirit of St. Louis" here refers to _____.A. the plane Lindbergh flew inB. the"flying fool"C. the hope of the people of St. LouisD. the city of St. Louis

Step Back in TimeDo you know that we live a lot longer now than the people who were born before us?One hundred years ago the average woman lived to be 45.But now,she can live until at least 80.One of the main reasons for people living longer is that we know how to look after ourselves better.We know which foods are good for us and what we have to eat to make sure our bodies get all the healthy things they need.We know why we sometimes get ill and what to do to get better again.And we know how important it is to do lots of exercise to keep our hearts beating healthily.But in order that we don't slip back into bad habits,let's have a look at what life was 100 years agoFamilies had between 15 and 20 children,although many babies didn't live long.from lots of diseases , especially rickets (佝偻病）and scurvy（坏血病）,which are bot diets.This is because many families were very poor and not able to feed their children well.Really poor families who lived in crowded cities like London and Manchester often slept standing up,bending over a piece of string,because there was no room for them to lie down.People didn't have fridges until the 1920s.They kept fresh food cold by storing it on windowsills（窗台板）,blocks of ice,or even burying it in the garden.Some children had to start work at the age of seven or eight to earn money for their pai lived 100 years ago,you might well be selling matchsticks（火柴杆）(a job done by many children）or working with your dad by now.People in the past preferred standing up to lying down when sleeping.A:Right B:Wrong C:Not mentioned

Everyone knows airline pricing is based on supply and demand. Fares are mores expensive during peak travel seasons like summer and to prime destinations like European capitals. So if a flight to Rome costs more than a flight to Milan you d think that demand for Rome must be higher or supply lower
What’s puzzling is that you can pay a high price to a given destination but a dramatically lower price for the exact same flight if you agree to go on to another destination.
Take Alitalia to Rome for instance for travel in August A round-trip economy flight directly to Rome leaving JFK at 10:05 p.m on Alitalia 611 on August 5 costs $1,655 when booked on April 30 Compare that to $903 for a round-trip economy ticket to Milan(stopping in Rome)leaving JFK on the exact same Alitalia 611 flight at 10:05 p.m on August 5. So why is Alitalia willing to fly you to Rome for $752 less than it would otherwise plus give you an extra one-and-a-half-hour flight to Milan?
Airlines have increased their profitability in recent years by segmenting the market for air travel and charging customers different prices for the same product. In this case the market is segmented based on demand for direct flights. Airlines know most people prefer the shortest route to their destination so they make customers pay up for the privilege of flying direct(They also make it a little more inconvenient if you don’t pay up for a direct flight in order to encourage you to fly direct)
When process become so obviously illogical it may be time to why air tickets can’t be transferred or resold just like any other normal product If the airlines are entitled to exploit the free market shouldn’t customers be allowed to do the same thing?

The Race Into SpaceAmerican millionaire Dennis Tito will always be famous.He was the first tourist in space."I spent sixty years on Earth and eight days in space and from my viewpoint,it was two separate lives,"Tito explained.He loxed his time in space."Being in space and looking back at the earth is one of the most rewarding experi-ences a human being can have."This kind of experience isn't cheap.It cost$20 million.However,Tito achieved his dream,so he was happy."For me it was a life dream.It was a dream that began when I didn't have any money,"he told reporters.On 24th,April 2002,Mark Shuttleworth became the world's second space tourist.Shuttleworth is a South African businessman.At the age of twenty-eight,he also paid $20 million for the eight-day trip.Both Tito and Shuttleworth bought their tickets from a company called Space Adventures.The company has around 100 people already on their waiting list for flights into space.The spaceship to take them doesn't exist yet.Many of the customers are people who like adventure.They are the kind of people who also want to climb Mount Qomolangma.Other customers are people who love space.However,these people are worried.Because it's so expensive,only very rich people can go into space.They want space travel to be available to more people.That day may soon be here.InterOrbital Systems(IOS)plans to send up to four tourists a week into space.The tours will depart from an island in Tonga.The company promises a package that includes forty-five days of astronaut training in Russia and California,seven days in space and a vacation in Tonga,for $2 million.However,space flight is still very dangerous.Bill Readdy is NASA's deputy assistant administrator for space flight.He says that the chances of dying are about 1 in 500.Because of this,it may take time before space tourism really takes off.You might be able to go up,but will you come down?Bill Readdy thinks space flight is very dangerous.A:RightB:WrongC:Not mentioned

Questions 11 to 15 are based on the following passage.
Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu (流感) may make a difference in how long the misery lasts.
The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the two apart. That’s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.
The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses—flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗), which is, for most people, the best way to fight the flu, according to the ALA.
But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for.
Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.
The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms.
Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症)，a rare but serious condition of the liver and central nervous system.
There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.
According to the author, knowing the cause of the misery will help（）A、shorten the duration of the illnessB、the patient buy medicine over the counterC、the patient obtain cheaper prescription drugsD、prevent people from catching colds and the flu

That’s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.
The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses—flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗), which is, for most people, the best way to fight the flu, according to the ALA.
But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for.
Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.
The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms.
Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症)，a rare but serious condition of the liver and central nervous system.
There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.
According to the passage, to combat the flu effectively, （）A、one should identify the virus which causes itB、one should consult a doctor as soon as possibleC、one should take medicine upon catching the diseaseD、one should remain alert when the disease is spreading

问答题Directions:In this section, there is one passage followed by 5 questions. Read the passage carefully, then answer the questions in as few words as possible (not more than 10 words). Remember to write the answers on the Answer Sheet. Questions 1-5 are based on the following passage. Many people today are worried about bird flu. They are afraid that it will pass from birds to humans and that thousands of people will die in a pandemic. In 1918 a flu virus killed about 50 million people around the world. The virus was called Spanish influenza (or Spanish flu, for short) because Spanish newspapers first described the disease. Now, after nine years of work, scientists in an American laboratory in Atlanta, Georgia, have produced a copy of the Spanish flu virus. They are also going to publish the genetic sequence of the virus on the Internet and some experts are afraid that other laboratories could copy the virus. Scientists have copied the virus because they want to understand why the 1918 Spanish flu pandemic killed so many people. In a report in the journal Science, Dr. Jeffery Taubenberger and a team of scientists in the USA show that the copied virus is extremely powerful. The scientists injected the virus into mice and the mice began to lose weight very quickly. They lost 13% of their weight in two days and all of the mice died within six days. “I didn’t expect it to be as lethal as it was,”Dr. Terrence Tumpey, one of the scientists in the team, told the journal Nature. In another experiment, they injected more mice with a normal type of flu. The mice lost weight at first but then they got better and did not die. The experiments showed that the mice with the Spanish flu virus had 39,000 times more flu virus in their bodies than the second group of mice. The scientists who copied the virus say their work has already provided important information about the virus and helps to explain why it is so lethal. But other experts are worried that the virus could escape from the laboratory. “Some people will think that they have really created a biological weapon,” said Professor Ronald Atlas of the University of Louisville in Kentucky. “I am even more worried now than I was before about the possibility of a flu pandemic. The 1918 flu pandemic started with bird flu and that might happen again today with Asian bird flu.” Some scientists are worried about the publication of the genetic sequence on the Internet. They are afraid that biologists could copy the virus using the information on the Internet. This could be very dangerous. It took a long time to copy the virus. Scientists used material taken from the lungs of people who died from the flu virus in 1918. In a second report in Nature, Taubenberger and his colleagues analyzed the genetic make-up of the virus. They were surprised to find that it was completely different from all the normal human flu viruses. This probably means that Spanish flu jumped from birds to humans and did not mix with a human virus first. This is very worrying for scientists because in the past everyone believed that a pandemic was only possible if a bird flu virus mixed with a human flu virus. Taubenberger says it is very important to know what changes in the virus caused the 1918 Spanish flu virus. This will help scientists to work out which viruses might cause a pandemic. The H5N1 bird flu in Asia is already changing and it could infect humans, he said. Viruses have escaped from high-security labs before. The SARS virus escaped at least twice, once in Taiwan and once in Singapore. But some scientists believe a pandemic will not happen even if the virus escapes, because most people are naturally immune and there are now a lot of drugs which protect people from flu. Questions: 1．When was the Spanish flu pandemic? 2．How many people died in the Spanish flu pandemic? 3．Where did the scientists produce a copy of the Spanish flu virus? 4．How quickly did the laboratory mice die? 5．What is H5N1?
