第三篇Infection of AIDSAccording to a report of the World Health Organization,this year will see 2.6 million deaths from AIDS,the highest yearly international total since the disease began to take hold in the late 1970s, despite questionable antiretro-viral drugs(抗逆转录酶病毒药)that staved off AIDS deaths in the richer countries.As things stood,the number of deaths was likely to increase for many years before peaking. The report said about half of all people who acquired HIV become infected before they turned 25 and usually died before their 35th birthdays of AIDS,which destroys the body's immune methods.Although ninety-five percent of people with HIV live in the developing world,battling HIV rates was still a challenge in the developed countries of the West,where there are"very worrying facts" that safe sex practices are dropping among gays.While AIDS deaths in the United States dropped by 42 percent between 1996 and 1997,the figure dropped by only half that between 1997 and last year.The report added that in Eastern Europe and Central Asia,the number of infected people had risen by a third this year,to 360,000.This was mainly due to an increase in the use of infected needles to inject drugs in Russia and the Ukraine. More than 2,700 cases of HIV were reported in Moscow in the fitst nine months of this year.Although cases of HIV remain relatively low in the Middle East,increasing use of injected drugs accounted for two thirds of new HIV cases in Bahrian last year,half in Iran and more than a third in Tunisia.There has been an increase in the number of people infected with HIV in Eastern Europe and Central Asia mainly because__________.A:most people were infected when staying in developed countries in the pastB:there were more cases of HIV presentC:in some countries more infected needles were used for the injection of drugsD:HIV reports were written with more points in these countries

Pedestrians Only1 .The concept of traffic-free shopping areas goes back a long time.During the Middle Ages,traffic-free shopping areas were built in Middle Eastern countries to allow people to shop in comfort and,more importantly,safety.As far back as 2,000 years ago,road traffic was banned from central Rome during the day to allow for the free movement of pedestrians (行人),and was only allowed in at night when shops and markets had closed for the day.In most other cities,however,pedestrians were forced to share the streets with horses,coaches and,later,with cars and other motorized vehicles.2 .The modem,traffic-free shopping street was born in Europe in the 1960s when both city populations and car ownership increased rapidly.Dirty gases from cars and the risks involved in crossing the road were beginning to make shopping an unpleasant and dangerous experience.Many believed the time was right for experimenting with car-free streets and shopping areas seemed the best place to start.3 .At first,there was resistance from shopkeepers.They believed that such a move would be bad for business.They argued that people would avoid streets if they were unable to get to them in their cars.When the first streets in Europe were closed to traffic,there were even noisy demonstrations,as may shopkeepers predicted they would lose customers.4 .However,research carried out afterwards in several European cities revealed some unexpected statistics.In Munich,Cologne and Hamburg,visitors to shopping areas increased by 5Opercent.On Copenhagen's main shopping street,shopkeepers reported sales increases of 25-40 percent.Shopkeepers in Minneapolis,the USA,were so impressed when they learnt this that they even offered to pay for the construction and maintenance costs of their own traffic-free streets.5 .With the arrival of the traffic-free shopping street,many shops,especially those selling things like clothes,food and smaller luxury items,prospered.Unfortunately,it wasn't good news for everyone, as shops selling furniture and larger electrical appliances(电器)actually saw their sales drop.Many of these were forced to move elsewhere,away from the city centre.In the l960s,dirty gases from cars made shopping_______.A:pedestriansB:North AmericaC:customersD:a bad experienceE:Middle Eastern countriesF:furniture sellers

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?
