Unit1 News:Outrageous shopping bills are a familiar nightmare for many compulsive shoppers．And contrary to the popular opinion，men suffer that nightmare nearly as often as women．A new survey finds that both genders are almost equally likely to suffer compulsive buying disorder, a condition marked by uncontrollable, unnecessary and unaffordable shopping sprees.Researchers used to estimate that between 2 and 16 percent of the US population suffered compulsive buying disorder, and that 90 percent of sufferers were female.But a 2004 telephone survey of more than 2,500 American adults found that 6 percent of women and about 5.5 percent of men are compulsive shoppers;that's more than 1 in 20 adults.The sexes do not shop at the same aisles though.Experts say that women are more likely to binge buy things like clothes or gilts for other people, while men tend to buy expensive electronics.This survey is the first to find such a high number of compulsive shoppers in the general population.Study authors hope that this finding can convince doctors of how many people are hurt by the disorder, so they can make finding a cure a priority.I'm Bill Blakemore in New York.S.C.1.W: Do you have a hobby, Kevin?

In Vail, Arizona, a new school with a new idea: no textbooks.White other students might be reading books, Empire students will read on their laptops.Jeremy Gypton, a history teacher at Empire High School in Vail, Arizona.Mr.Gypton, tell us about the assignment that you've already given, that might otherwise have involved a textbook，but in this case involves a computer.Mr.Gypton: Well, with the, with history I try to use as many primary source documents as possible.I actually just recently had my students, studying...my American History students, studying the French-Indian War and its impact.And that sort of document is just not available in a traditional textbook, I would have to say, “Go online or go to a library and find a copy”, whereas with the laptops and with the resources they're using, they have immediate access to it.Reporter: What's the point here? Is it to get Io primary sources or is it to use a medium that youngsters today are more familiar with? How do you, how do you describe what you arc doing'? Mr.Gypton: When it comes to our, I guess, our reasoning, these are the students who've grown up with the computer, with the Internet, er, as, as kind of organic to their environment.It's not an add-on, like it, like it was to me.And this is normal for them.And so, limiting them, by like sort of a traditional, maybe thousand page textbook is, from their perspective, I think a little bit abnormal, because they are used to being able to reach out, and view one topic from 20 different angles, as opposed to just the one angle that a textbook would present.Reporter: Jeremy Gypton, thank you very much for talking with you.Mr.Gypton: Thanks so much for your time.S.C.1.W: Mr.Williams, where did you receive your Bachelor's degree in engineering?

W: I watch mainly news programmes mid classic movies.I hate commercials.There is a lot more advertising than there used to be.M: Nowadays, whatever you're doing in your daily life, it's quite difficult to get away from ads in one tbrm or another.They're all around you!Advertising has always been part of our life.Q: What can be inferred from the conversation?

barriers, both in architecture and in attitude.Its purpose its purpose is to give the disabled access not only to buildings but to every opportunity in society.Now, I strongly believe our nation must give its full support to the caregivers who are helping people with disabilities live independent lives.S.C.1.W: Mark, what’s wrong with you?

Acid Rain Damage from acid rain is widespread not just in eastern North America, but throughout Europe, Japan, China, and Southeast Asia.Is the rain that's falling on your umbrella acidic?

A listener's question on today's ”Earth and Sky“.JB: This is ”Earth and Sky“.with a question from Sandra Renee of Olive Hill, Kentucky.She asks, ”How do you know when it rains that it's not acid rain, and what exactly acid rain'?“ DB: Sandra, you need a pH meter to reliably measure the acidity of rain or snow.But in certain parts of the US--especially in the Northeast--you can probably assume that most rain will be at least somewhat acidic.Westerly winds move pollutants eastward, so the eastern US gets more acid rain.JB: Acid rain happens when airborne acids fail down to earth in rain.Electrical utility plants plaints that bum fossil fuels emit chemicals into the atmosphere that react with water and other chemicals in the air to form sulfuric acid, nitric acid--the ”acid“ in acid rain You don't have to live next door to a power plant to get showered by acid rain.The~ acid pollutants reach high into the atmosphere and can travel with wind currents for hundreds of kilometers.DB: The acids in acid rain are corrosive chemicals that leach nutrients from the soil slow the growth of trees, poison lakes and combine with other chemicals to form urban smog.The simplest way to curtail acid rain is to use less energy from fossil fuels.JB: Special thanks today to the Camille & Henry Dreyfus Foundation, a private foundation dedicated to advancing research and education in the chemical sciences.We're Block Byrd for ”Earth and Sky".S.C.1.W: Did you know that we waste hundreds of gallons of water every day, simply because people don't turn off their taps properly?

A)How to turn off taps properly.B)How to save water every day.C)How to switch off light in the house.D)How to protect water and trees in nature.2.M: I think government should do whatever is necessary to create more wild animal preserves.They should raise money through environmental awareness campaigns.W: Maybe people could make voluntary contributions when they file their taxes.M: That's a good idea.That way whoever wants to contribute can, but it's not obligatory Q: What does the man mean? A)It is a good idea to set up more wild animal preserves.B)It is necessary to raise money through awareness campaigns.C)It is a good idea for people to make voluntary contributions.D)It is people's obligation to contribute money.3.W: I heard about the tornado on the radio in Texas.M: Was it as bad as the one in Louisiana?
