PITTSBURGH For most people, snakes seem unpleasant or even threatening. But Howie Choset sees in their delicate movements a way to save lives.

The 37-year-old Carnegie Mellon University professor has spent years developing snake-like robots he hopes will eventually slide through fallen buildings in search of victims trapped after natural disasters or other emergencies.

Dan Kara is president of Robotics Trends, a Northboro, Mass.-based company that publishes an online industry magazine and runs robotics trade shows. He said there are other snake-like robots being developed, mainly at universities, but didn’t know of one that could climb pipes.

The Carnegie Mellon machines are designed to carry cameras and electronic sensors and can be controlled with a joystick(操纵杆). They move smoothly with the help of small electric motors, or servos, commonly used by hobbyists in model airplanes.

Built from lightweight materials, the robots are about the size of a human arm or smaller. They can sense which way is up, but are only as good as their human operators, Choset added.

Sam Stover, a search term manager with the Federal Emergency Management Agency based in Indiana, said snake-type robots would offer greater mobility than equipment currently available, such as cameras attached to extendable roles.

“It just allows us to do something we’ve been able to do before,” Stover said, “We needed them yesterday.

He said sniffer dogs are still the best search tool for rescue workers, but that they can only be used effectively when workers have access to damaged building.

Stover, among the rescue workers who handled the aftermath (后果) of Hurricane Katrina, said snake robots would have helped rescuers search flooded houses in that disaster.

Choset said the robots may not be ready for use for another five to ten years, depending on funding.

72. Which institution is responsible for the development of Choset’s robots?

A. Robotics Trends.                      B. Pittsburgh City Council.

C. Carnegie Mellon University.         D. Federal Emergency Management Agency.

B.      can be used by hobbyists in model airplanes

C.      can find victims more quickly than a sniffer dog

74. By saying “We needed them yesterday” (paragraph 7), Stover means that snake-like robots _____.

A.      could help handle the aftermath of Hurricane Katrina

B.      would have been put to use in past rescue work

C.      helped rescuers search flooded houses yesterday

D.     were in greater need yesterday than today

Increasingly, Americans are becoming their own doctors, by going online to diagnose their symptoms, order home health tests or medical devices, or even self-treat their illnesses with drugs from Internet pharmacies(药店). Some avoid doctors because of the high cost of medical care, especially if they lack health insurance. Or they may stay because they find it embarrassing to discuss their weight, alcohol consumption or couch potato habits. Patients may also fear what they might learn about their health, or they distrust physicians because of negative experiences in the past. But playing doctor can also be a deadly game.

Every day, more than six million Americans turn to the Internet for medical answers most of them aren’t nearly skeptical enough of what they find. A 2002 survey by the Pew Internet & American Life Project found that 72 percent of those surveyed believe all or most of what they read on health websites. They shouldn’t. Look up “headache”, and the chances of finding reliable and complete information, free from a motivation for commercial gain, are only one in ten, reports an April 2005 Brown Medical School study. Of the 169 websites the researchers rated, only 16 scored as “high quality”. Recent studies found faulty facts about all sorts of other disorders, causing one research team to warn that a large amount of incomplete, inaccurate and even dangerous information exists on the Internet.

The problem is most people don’t know the safe way to surf the Web. “They use a search engine like Google, get 18 trillion choices and start clicking. But that’s risky, because almost anybody can put up a site that looks authoritative(权威的), so it’d hard to know if what you’re reading is reasonable or not,” says Dr. Sarah Bass from the National Cancer Institute.

68. According to the text, an increasing number of American _____.

A.      are suffering from mental disorders

D.     are skeptical about surfing medical websites

69. Some Americans stay away from doctors because they _____.

A.      find medical devices easy to operate

B.      prefer to be diagnosed online by doctors

C.      are afraid to face the truth of their health

D.     are afraid to misuse their health insurance

70. According to the study of Brown Medical School, ______.

A.      more than 6 million Americans distrust doctors

B.      only 1/10 of medical websites aim to make a profit

C.      about 1/10 of the websites surveyed are of high quality

D.     72% of health websites offer incomplete and faulty facts

71. Which of the following is the author’s main argument?

A.      It’s cheap to self-treat your own illness.

B.      It’s embarrassing to discuss your bad habits.

C.      It’s reasonable to put up a medical website.

D.     It’s dangerous to be your own doctor.

November not only marks the publication of Toni Morrison’s eagerly anticipated(期待) eighth novel, Love, but it is also the tenth anniversary of her Nobel Prize for Literature. Morrison is the first black woman to receive a Nobel, and so honored before her in literature are only two black men:Wole Soyinka, the Nigerian playwright, poet and novelist, in 1986; and Derek Walcott, the Caribbean-born poet, in 1992. But Morrison is also the first and only American-born Nobel prizewinner for literature since 1962, the year novelist John Steinbeck received the award.

Like Song of Solomon, Love is a multigenerational story, revealing the personal and communal legacy() of an outstanding black family. As Morrison scholars will tell you, Love is the third volume of a literary master’s trilogy(三部曲)investigating the many complexities of love. This trilogy began with Beloved(1988), which deals with a black mother’s love under slavery and in freedom. Jazzy(1993), the second volume, tells a story of romantic love in 1920s Harlem. This latest novel looks back from the 1970s to the 1940s and 50s.

The emotional center of Love is Bill Cosey, the former owner and host of the shabby Cosey’s Hotel and Resort in Silk, North Carolina, described in the novel as “the best and best-known vacation sport for colored folk on the East Coast.” We get to know Cosey through the memories of five women who survive and love him: his granddaughter, his widow, two former employees, and a homeless young girl.

The latest novel, Love, had been described in the promotional material from her publisher as “Morrison’s most accessible work since Song of Solomon.” This comparison to her third novel, published in 1977, was an effective selling point.

Short and shy, Ben Saunders was the last kid in his class picked for any sports team. “Football, tennis Cricket―anything with a round ball, I was useless, “he says now with a laugh. But back then he was the object of jokes in school gym classes in England’s rural Devonshire.

It was a mountain bike he received for his 15th birthday that changed him. At first the teen went biking alone in a nearby forest. Then he began to cycle along with a runner friend. Gradually, Saunders set his mind building up his body, increasing his speed, strength and endurance. At age 18, he ran his first marathon.

The following year, he met John Ridgway, who became famous in the 1960s for rowing an open boat across the Atlantic Ocean. Saunders was hired as an instructor at Ridgway’s school of Adventure in Scotland, where he learned about the older man’s cold-water exploits(成就).Intrigued, Saunders read all he could about Arctic explorers and North Pole expeditions, then decided that this would be his future.

Journeys to the Pole aren’t the usual holidays for British country boys, and many people dismissed his dream as fantasy. “John Ridgway was one of the few who didn’t say, ‘You are completely crazy,’” Saunders says.

In 2001, after becoming a skilled skier, Saunders started his first long-distance expedition toward the North Pole. He suffered frostbite, had a closer encounter(遭遇) with a polar bear and pushed his body to the limit.

Saunders has since become the youngest person to ski alone to the North Pole, and he’s skied more of the Arctic by himself than any other Briton. His old playmates would not believe the transformation.

This October, Saunders, 27, heads south to explore from the coast of Antarctica to the South Pole and back, an 1800-mile journey that has never been completed on skis.
