Gulf Wracked By Katrina’s Latest Legacy-Disease, Poisons, Mold
A month after Hurricane Katrina tore through the U.S. Gulf Coast, medical experts are now struggling with the latest crisis in the region; contamination(污染).
Katrina left New Orleans and other communities tainted with oil, sewage, and possibly poisons leached from federal toxic waste sites, the U.S. Environmental Protection Agency (EPA) says.
The pollution, combined with the lack of regular medical services in the region, has raised serious questions about the safety of New Orleans and other coastal towns as people longing for home begin to go back.
"I don’t think New Orleans is safe for people to return to, from a public health and environmental health standpoint," said Miriam Aschkenasy, an environmental health expert working with Oxfam America in the region.
Much of the contamination rests in the brown, filmy sediment(沉淀物) left behind by Katrina’s polluted floodwaters.
Recent EPA tests of the sediment confirmed high levels of E. coli bacteria, oil and gas chemicals, and lead, as well as varying quantities of arsenic.
The health risks posed by the sediment are immediate, experts say, because the sludge(淤泥) is nearly impossible for returning residents to avoid. In New Orleans, it covers every surface that was flooded, from cars and now-dead lawns to the entire contents of flooded homes, stores, hospitals, and schools.
"When people come back, they are exposed to the sediment," said Wilma Subra, a chemist from New Iberia, Louisiana, who is analyzing the sediment. "It’s in their yards and houses."
Old Pollution Resurfacing
Plaquemines Parish, a rural county on the peninsula south of New Orleans, is now covered with even more toxic sediment than it was two weeks ago, thanks to Hurricane Rita.
"Six inches up to one foot (15 to 30 centimeters) of sludge," Subra reported.
Much of the sludge in Plaquemines is the product of nearby bayous and bay bottoms, where sediment was lifted up by Katrina’s and Rita’s storm surges.
The sediment has been polluted over the years with industrial chemicals and heavy metals, said Subra, who tested the sediment for the Southern Mutual Help Association, a nonprofit organization in New Iberia, Louisiana.
"These water bodies have received industrial wastes for decades," she said. "This material has toxic chemicals, metals, and organic petrochemicals(石化产品)."
Matters have only been made worse by multiple oil spills caused by Katrina and Rita. According to the U.S. Coast Guard, 11 oil spills have occurred in southern Louisiana, totaling 7.4 million gallons (28 million liters) of oil, most of which has been contained.
Bacteria levels are also especially high in the Plaquemines sludge, said Rodney Mallett, spokesperson for the Louisiana Department of Environmental Quality.
"The sewage treatment plants were underwater," he explained. "Between the animal waste and the human waste, you’ve got a lot of bacteria."
Protection Kits
Health and environmental agencies are advising people to avoid contact with the sludge. They recommend that people wear gloves, goggles, and dust masks, and that they wash promptly if exposure occurs.
EPA officials are directing people to its Web site (www.epa.gov) to inform themselves of the contamination risks.
But most people returning to the area don’t have computers to get that information, said Erik Olson, an attorney for the Natural Resources Defense Council, an environmental advocacy group.
"If you [do] read the Web site," he added, "you practically have to have a degree in chemistry to understand it."
To better inform people of health risks, the Southern Mutual Help Association and Oxfam America are developing a program to give every returning resident a protective kit.
Each kit would contain waterproof suits, goggles(风镜), shoe covers, and masks, along with information about potential hazards, Volunteers would give out the kits at the security checkpoints that now stand at the major entrances to affected cities.
The groups have made a hundred demonstration kits, which cost about $100 (U.S.) each to produce, and have shown them to state leaders in Louisiana.
"The governor is really in favor of this," Subra said. "We just have to determine how we’re going to fund them."
Toxic Mold Blooms
In addition to the toxic sediment, sprawling blooms of mold have now taken hold in many flooded homes. "The mold is growing everywhere-homes are just coated with it," Subra said.
The problem has become so widespread that federal health officials warned Wednesday of allergic reactions and toxic responses to the mold. Professionals should be hired to clean mold that covers more than ten square feet (one square meter), they urged.
"Those [surfaces] that can’t be cleaned need to be removed," said Steven Redd, chief of the Air Pollution and Respiratory Health Branch of the U.S. Centers for Disease Control and Prevention (CDC).
The effects of the mold are already surfacing in Mississippi, where respiratory(呼吸的) problems are among the illnesses doctors there are reporting.
"We’re seeing a lot of asthma from inhaling the mold," said Richard Paat, team leader of a temporary East Biloxi clinic. "And mouth sores from the bad water."
Due to contact with unclean water, 33 people in the flood zone have contracted Vibrio infections, according to the CDC. The infections are caused by a family of bacteria that live in contaminated salt water. They can cause serious illness, especially in people with compromised immune systems.
To date, six people have died from Vibrio infections.
"People had open wound and walked through floodwater with sewage in it," CDC spokesperson Von Roebuck said. "And these folks were having these wounds infected with Vibrio."
Disaster Response Care
"This is a highly contaminated area," said Susan Briggs, the physician overseeing FEMA’s disaster-response medical teams in Louisiana and Alabama.
Her teams have been inoculating residents for tetanus and Hepatitis A and B. Hepatitis is a danger when people are exposed to sewage, through water or food, Briggs explained. Tetanus can occur when people cut themselves on unclean materials, as may happen when cleaning debris.
The rudimentary(根本的) living conditions in many Katrina-struck areas make it more likely that people will get sick and injured, Briggs said.
"They have no electricity, no clean water, no air conditioning," she said. "There are collapsed structures and stray animals. There are huge amounts of stray dogs, and people have been bitten."
Briggs and other doctors in the area have been treating many cases of diarrhea, rashes, and upper-respiratory illnesses.
All of these conditions are to be expected after natural disasters, according to the CDC. But it’s too soon to know if these ailments are related to contamination, the CDC’s Roebuck said.
"We’re looking at that question," he said. "We’d like to know the answer."

Part II Reading Comprehension (Skimming and Scanning) (15 minutes)
Directions: In this part, you will have 15 minutes to go over the passage quickly. For questions 1-7, choose the best answer from the four choices marked A), B), C) and D). For questions 8-10, complete the sentences with the information given in the passage.
Selling Expertise on the Internet for Extra Cash
Teresa Estes, a licensed mental-health counselor, watched as business at her private practice decreased last year. Then the single mother turned to her keyboard to boost her income.
Ms. Estes applied to become an “expert” on LivePerson Inc., a Web site where clients pay for online chat time with professionals and advisers of all fields. For $1. a minute — a rate she set — the 39-year-old from Marianna, Fla., dispenses advice to clients around the globe. She spends about four hours a day online, often at night, when her daughter has gone to bed.
“It was the economy,” she says of her move to take her skills online. “Live Person is more profitable than my private practice.” Ms. Estes had charged her private clients up to $75 an hour.
As the recession deepens, a small but growing number of people are taking their skills online, offering expertise or performing specified tasks for a fee. Labor-at-the-keyboard sites are gaining popularity as people increasingly turn to the Web in search of work. Internet job-search sites saw a 51% rise in traffic from January 2008 to January 2009, according to comScore Media Metrix, to 26.7 million unique visitors.
Among the many fee-for-service Web sites out there, at least three are attracting a significant number of users —though consumers should exercise a healthy degree of skepticism when consulting any of these sites. Live Person seeks out experts on a slew of topics, including mental health, financial services, shopping and fashion, as well as psychics and spiritual advisers. Mechanical Turk, a Web service run by Amazon.com Inc., pays workers to perform tasks, such as cataloging products online. Associated Content pays contributors to write articles on a wide range of subjects, from organic flower gardening to how to apply for financial aid .
Live Person went public in 2001, and the current version of the site was launched in late 2007. Today, the site has 30,000 registered experts, attracting an average of 100,000 people a year who pay for the offered services, says Chief Executive Officer Robert LoCascio. Roughly 3,500 people have made contributing to the site their full-time job, he says.
Live Person says it vets contributors’ qualifications, such as medical licenses or financial certification, through a third party, and relies heavily on its community reviews. Some 200 people a day apply to be Live Person experts, up from 120 a year ago, says Mr. LoCascio. Once cleared, advisers work with clients on a cost-per-minute basis set by the adviser. The site takes a commission of between 30% and 35%.
Associated Content, by contrast, reviews submissions in house and then decides how much to pay for them. The site, which specializes in how-to pieces and feature stories on news topics, had 237,000 registered contributors and more than one million content pieces as of February, both about double from the same month a year ago.
After posting the content, the site sells advertisements against it and distributes it to other companies, such as online shoe retailer Zappos, which use the content on their own Web sites. If Associated Content accepts a submission (it says it rejects about 25% of them), the author gets between $5 and $30, plus $1.50 for each 1,000 page views. An ability to write “search-engine-optimized” content, an industry term for generating good Google results, helps, says site founder Luke Beatty.
People are not only looking for payment but also establishing their credentials “as somebody with experience”, he says. Writing about a specific profession, such as law or real estate, helps raise a person’s profile online, enhancing his job searches, says Mr. Beatty.
Sabah Karimi, a 26-year-old from Orlando, Fla., left a career in marketing to become a full-time freelance writer and now spends between 8 and 10 hours a week writing for Associated Content. She has been at it for about three years and says she earns roughly $1,000 a month from her past and current submissions.
Ms. Karimi cautions newcomers to Associated Content that it takes time to build up earnings. She says she learned how to write articles that would bring traffic and often looks for newsy ideas that will attract readers.
Mechanical Turk, by contrast, is based on “crowd sourcing”, or breaking a task into lots of tiny pieces and giving it to a big group of people to complete quickly. Most of these jobs — which the site calls HITs, for human intelligence tasks — pay just a few cents. Efficient MTurkers, as they call themselves, can make more than $100 a week doing things such as finding someone’s email address or labeling images of a particular animal in a photograph.
Amazon says that MTurk now has 200,000 workers from 100 different countries, but it doesn’t keep track of past figures.
The site — named for an 18th-century stunt involving a turbaned chess-playing “machine” with an actual chess master hidden within —began as a way to help Amazon manage its product database, says Sharon Chiarella, vice president of Amazon Mechanical Turk. Amazon uses the site to help sort images and content, paying people a few cents a task. Mechanical Turk also serves a variety of companies who need Web tasks performed, especially those that require a human element. Test-prep startup Knewton Inc., for example, uses it extensively for focus-group-type tasks, as well as enlisting people to take its practice tests.
Keri Knutson, a mother of five from Independence, La., discovered Mechanical Turk when her eldest son was headed for college. Ms. Knutson, now 45, needed money for his tuition and fees. She took on all kinds of low-paying but easy tasks at the beginning, from finding a place to purchase a specific item to identifying the name of a street in a photograph.
People looking to make money online as fee-for-service experts should read the fine print. Live Person has one of the more formal payment systems, requiring users to sign up for an account before talking with an expert. Some sites, including Associated Content and Mechanical Turk, reserve the right to refuse payment if a task is not completed satisfactorily.
Most sites have a robust community of workers who regularly offer one another tips on which tasks pay the best. Mechanical Turk users have an independent site called Turker Nation (turkers.proboards80.com), which reviews the companies that solicit (索求) and pay for tasks so that workers can check a company’s record before taking on a task.
Consumers who use these sites also need to exercise caution. Relying on legal or medical advice from an unknown online source has obvious drawbacks, and the Web sites acknowledge that some users have registered complaints about the advice offered on the sites. LivePerson warns consumers to offer their financial and personal details with care.
For the workers on these sites, even incremental sources of income are helpful these days. Ms. Knutson now spends the majority of her time transcribing Web audio and video for clients, earning about $250 a week for 30 hours of work. She says she has seen more competition lately but is determined to keep up her weekly pace.
“If I didn’t have this money,” she says, “we’d be struggling to find what to eat every week.”

For many years, scientists couldn’t figure out how atoms and molecules on the Earth combined to make living things. Plants, fish, dinosaurs, and people are made of atoms and molecules, but they are put together in a more complicated way than the molecules in the primitive ocean. What’s more, living things have energy and can reproduce, while the chemicals on the Earth 4 billion years ago were lifeless.
After years of study, scientists figured out that living things, including human bodies, are basically made of amino acids and nucleotide bases. These are molecules with millions of hydrogen, carbon, nitrogen, and oxygen atoms. How could such complicated molecules have been formed in the primitive soup? Scientists were stumped.
Then, in 1953, two scientists named Harold Urey and Stanley L. Miller did a very simple experiment to find out what had happened on the Primitive Earth. They set up some tubes and bottles in a closed loop, and put in some of the same gases that were present in the atmosphere 4 billion years ago: water vapor, ammonia, carbon dioxide, methane, and hydrogen.
Then they shot an electric spark through the gases to simulate bolts of lightning on the ancient Earth, circulated the gases through some water, sent them back for more sparks, and so on. After seven days, the water that the gases had been bubbling through had turned brown. Some new chemicals were dissolved in it. When Miller and Urey analyzed the liquid, they found that it contained amino acids—the very kind of molecules found in all living things.

C) plants, fish, dinosaurs and human beings
D) the primitive soup
1. B 细节题从文中第三段可知:“Then, in 1953, two scientists…did a very simple experiment to find out what had happened on the Primitive Earth.”这说明从1953年起,人类才开始弄明白地球上的生物是怎样由原子和分子结合而产生的。因此B)是正确选项。
2. A 细节题答案从第二段开头可直接找到:“…, scientists figured out that living things, including human bodies, are basically made of amino acids and nucleotide bases.”
3. A 细节题答案第三段中直接给出:“…, Harold. Urey and Stanley L. Miller did a very simple experiment to find out what had happened on the Primitive Earth.” 紧接着作者又指出是在“…4 billion years ago…”。
4. D 语义辨析题见原文最后一句话:“When Miller and Urey analyzed the liquid, they found that it contained…”。“当米勒和尤里对液体进行分析时,他们发现它包含有……”。很明显it指的就是从句里的liquid。
5. C 综合判断题文中第一段第二句话暗示了该题答案:“Plants, fish, dinosaurs, and people are made of atoms and molecules…”。段“LivePerson says it vets contributors’ qualifications, such as medical licenses or financial certification, through a third party, and relies heavily on its community reviews.”可知,LivePerson对这些在网上用知识和技术赚钱的人会进行审核,例如行医许可或经济师证书等,通过以社区论坛为主的第三方进行认证。
10. 100 different countries。参见第十四段“Amazon says that MTurk now has 200,000 workers from 100 different countries ...”可知,MTurk现在有来自100个国家的20万名“网络员工”。

No one knows when the first calendar was developed. But it seems possible that it was based on lunar months. When people started farming, the sages of the tribes became very important, they studied the sky and gathered enough information to be able to predict when the seasons would change, and were able to announce when it was time to plant crops.
The divisions of time we use today were developed in ancient Babylonia 4,000 years ago.Babylonian astronomers believed the sun moved around the Earth every 365 days.They divided the trip into 12 equal parts, each with 30 days. Then they divided each day into 24 equal parts, or hours, and divided each hour into 60 minutes, each minute into 60 seconds.
Humans have used many devices to measure time; the sundial (日晷) was one of the earliest and simplest. However, the sundial worked well only when the weather was fine, so other ways of measuring the passing of time were invented. One device was the hourglass(沙漏). By the eighteenth century, people had developed mechanical clocks and watches. So we have devices to mark the passing of time, but what time is it now? Clocks in different parts of the world do not show the same time at the same time, because time on Earth is set by the sun’s positions in the sky above us. As international communications and travel grew, it became clear that a way to establish a common time for all parts of the world was needed. In 1884, an international conference divided the world into 24 time zones, each zone represents one hour. The astronomical observatory in Greenwich, England, was chosen as the starting point for the time zones. Twelve zones are west of Greenwich. Twelve are east. The time at Greenwich measured by the sun is considered by astronomers to be Universal Time, also known as Greenwich Mean Time.
1. Which of the following is the best title for this passage?
A) The Development of Universal Time.
B) Different Ways to Measure Time.
C) Why We Measure Time the Way We do.
D) How the Calendar Came into being.
2. What does the example of Babylonia astronomers reveal?
A) It reveals Babylonians’wisdom that was absent elsewhere.
B) It reveals the origin of our time measurements.
C) It reveals the limits of some time measurements.
D) It reveals the stability of time measurements.
3. The author mentions all of the following ways to measure time EXCEPT .
A) sundial B) hourglass C) electric clock D) mechanical clock
4. According to the passage, Greenwich Mean Time __________.
A) provides a common time for all parts of the world
B) is calculated from the sun
C) is the 12th of the 24 time zones
D) was named after an international conference
5. With which of the following statements would the author be most likely to agree?
A) Time measurements have changed in response to need and technological development.
B) In ancient Babylonia, 12 was the basic division of time.
C) The first calendar was developed because the sages of tribes were intelligent.
D) Universal Time is so named because it is applicable throughout the universe.
1. C 主旨题本文共三段。第一段讲日历起源之因;第二段讲作为现代时间概念的基础,古巴比伦如何划分年月日时分秒;第三段提及先后出现的测量时间的各种工具,并讲述“世界时”如何顺应时代发展而产生。A),B)和D)项都只概括了本文的部分内容,只有C)项是对全文的总结。
2. B 综合判断题C)项在文章中没有提及,D)项不正确。本文的主题是计时方式的发展,并未强调某个民族智慧过人,A)项也不正确。
3. C 细节题根据题干可定位于第三段前半部分,答案是C。
4. B 细节题解题依据是“The time at Greenwich measured by the sun is…”。不过考生不一定留意了这个后置定语。相反,受“Twelve zones are west of Greenwich. Twelve are east.”的影响,可能会误选C)项。其实,这里是24个时区的“the starting point”,也就是第一个时区。
5. A 综合判断题C)项提到的日历出现就是其中一个例证,第三段还提到sundial, hourglass, mechanical clocks and watches和Greenwich Mean Time的出现,这都是随着人类社会发展的需要出现的。C)项错在将日历出现归因于一小部分人的高智商,真正的原因其实是“When people started farming…”。此外,Universal Time并非全宇宙通用,它只适用于全球24个时区,故D)项也不正确。
