In this Pennsylvania city, Pittsburgh is shrinking but getting wealthier. Since 2000, its population has declined by 95,000 while its income per capita (人均) has shot up 24 percent. The trend is taking hold in many other cities, like Buffalo in New York, Providence in Rhode Island and New Orleans.
Some of these areas have created more high-paying jobs in energy, health care or education. Others have managed to reshape their producing industry for a new economy. Higher-paying jobs have a greater effect because they create demand for additional services. "The story in Pittsburgh is very positive, and other areas are looking at it as an example of the transformation that might be possible,” said Guhan Venkatu, who wrote an economic history of the area called “Rust and Renewal” for the Federal Reserve Bank of Cleveland.
Carnegie Mellon University and the University of Pittsburgh have helped bring tech jobs and innovation(革新) to the area by sponsoring tech centers that help graduates start companies without moving to Silicon Valley or San Francisco. This has helped keep Pittsburgh's educated young population growing even as the entire population in the city has dropped.
Pittsburgh has more STEM (science, technology, engineering and math) jobs than other shrinking cities, about 80, 000 or 7% of all jobs. STEM jobs add productivity and income growth to the area. Manufacturers of high-tech medical equipment in the Pittsburgh area also have doubled employment in the last 10 years.
However, some experts question whether growing income per capita can really make up for a declining population. According to Patrick Adler, a researcher at the University of Toronto, population loss does matter if it means lower-skilled workers have fled because of a lack of opportunity. What's more, high-paying jobs in education and health care can disappear if the population declines too greatly. So it'd be wise to find ways to increase the population.
1.In what aspect does Pittsburgh set a good example?
A. Transforming old energy into new energy. B. Prohibiting the manufacturing.
C. Creating more well-paid jobs. D. Sponsoring higher education.
2.How do some academic institutions help with the local economy ?
A. By helping to attract more talents from home and abroad.
B. By providing much technical support to local companies.
C. By hosting tech centers to allow local educated graduates to stay.
D. By assisting in employing a large number of educated youths.
3.Why is Patrick Adler mentioned in the last paragraph?
A. To suggest increasing high-paying jobs.
B. To raise doubts about growing income per capita.
C. To tell a reason why lower-skilled workers flee.
D. To show the disadvantage of a declining population.

A new study, a project of the researchers from the University of Pittsburgh in Pennsylvania, finds the fitness tracker probably does not help with weight loss.
The devices are designed to record your physical activity. They are usually worn around the wrist, where they measure a person’s heart rate. The research team looked at two groups of individuals. The first wore a fitness tracker and took part in health counseling (咨询) with experts to consider the best weight-loss plan. The researchers compared this group with people who only got health counseling.
The study found that those only speaking with the health experts lost nearly 6 kilograms, but those using a fitness tracker lost only 3.5 kilograms. John Jakicic, the lead researcher, questioned the use of electronic devices for weight control in place of “effective behavioral counseling for physical activity and diet. ”
The study involved 470 subjects aged between 18 and 35. Some of them were overweight, while others were considered obese (肥胖的). Over three fourths of the subjects were women. All the subjects were told to increase physical activity and start on a low-calorie diet. They had their weight measured once every six months. After six months, researchers divided the group into two parts: one continued with monthly counseling, while members of the other group were given a fitness tracker. Eighteen months later, both groups “showed significant improvements in fitness, physical activity, and diet,” with no major difference between groups. However, when it came to losing weight, the people who only spoke with experts lost nearly twice as much weight.
Jakicic said, “the study’s findings are important because effective long-term treatments are needed to address America’s obesity. ” More information is needed, he added, to learn how to best use these devices to change “physical activity and diet behaviors” in adults who want to lose weight.
1.All the subjects in the study were asked to ________.
A. start on a high-calorie diet B. wear a fitness tracker
C. increase physical activities D. record their heart rates
2.Why does Jakicic think the findings are important?
A. Wearing fitness trackers hardly helps people lose weight.
B. Physical activity and diet have no effect on weight loss.
C. Handling obesity requires effective long-term treatments.
D. There are great differences in fitness between both groups.
3.What can we infer about the study mentioned in the text?
A. The study went on for about two years.
B. More than 120 men took part in the study.
C. Health counseling helps lose almost 6 kilograms.
D. Wearing a fitness tracker is useful for keeping slim.
4.The purpose of the text is to ________.
A. describe how the researchers were conducting the study
B. indicate regular counseling for weight control is necessary
C. convince readers to wear fitness trackers for weight control
D. warn women are more likely to suffer from weight problems

Public schools in New York,America’s biggest city, commonly have numbers for names.But this is unusual.In the United States,the process of naming a school often involves parents and the community
as well as elected school leaders.
Researchers say school names can show civic (市民的) values and also shape them. For example,naming a school after a historic person becomes a way to teach students about that person’s importance in history.
A new study examines the naming of American public schools.The study is from the Manhattan Institute,an organization that does public policy research.The study shows that fewer and fewer schools are being named after people.Instead。more schools are being named after the local areas or natural features like hills.trees or animals.The researchers say these changes raise questions about the civic duty of public education.
The looked at seven states with 20% of all public school students in the country. They found the similar result in every state: new school are less likely to be named after people. This is true especially with presidents. For example, in Arizona, public school in the past 20 years were almost fifty times more likely to be named after such things as landforms or plants .
School officials say they try to choose names that will not offend anyone. For example, a few years ago the city of New Orleans banned the naming of any school after a person who owned slaves. Other school system have rules against naming new schools after any person, living or dead .
The researchers say naming a school after a person can lead it important debates about democratic values. They call for more research to identify the causes and effects of the changes in school names.
The causes may include changes in American culture as well as in the political control of school systems. One area worth exploring , they say, is the link between trends in school names and weak results for public schools on measures of civic education.
1.More schools are being named after the following EXCEPT ________ .
A.hills | B.trees | C.animals | D.people |
2.What does “they” in paragraph 7 refer to ?
A.School officials | B.Public schools | C.The researchers | D.Democratic values |
3. If the passage appears in a newspaper, which column will it be ?
A.Culture | B.Science | C.Travel | D.Entertainment |
4. What’s the best title for the passage ?
A.Few Us Public School Now Are Named after people |
B.Public Schools In New York Have Numbers for Names |
C.The Various Origins of America Schools |
D.US Public Schools Value the Names of Great Persons |

Philadelphia, Pennsylvania is America’s fifth largest city. Once a major American colonial city, it is the home of America’s first library, its first hospital, and its first zoo. Now it is also the first US city to be named a World Heritage City. On November 6, 2015, Philadelphia joined more than 260 other cities that have been recognized for their influence on the world. These cities include Paris, France, Florence, Italy, and Cairo, Egypt.
“Today marks the start of a new and exciting chapter in the history of Philadelphia,” remarked Philadelphia Mayor Michael Nutter when the announcement was made. “As a World Heritage City, Philadelphia is being officially recognized on the global stage for its wealth of contributions to the world.
To be named a World Heritage City, a city must be home to a UNESCO World Heritage site. UNESCO World Heritage sites are selected for their universal value and significance. For Philadelphia, the site is Independence Hall.
Independence Hall is where two of the most important documents in US history—the Declaration of Independence and the US Constitution—were adopted. The Declaration of Independence, approved on July 4, 1776, united the 13 former British colonies and declared them independent from British rule. The US Constitution, signed in 1787, established the American democratic system of government. A democracy is a system of government in which the people elect their leaders. The Constitution later spelled out the basic freedoms American citizens have.
Philadelphia Deputy Mayor Alan Greenberger says the city’s selection as a World Heritage City also reflects its educational, cultural, and economic achievements. The city is home to dozens of colleges and universities, and many museums, such as the Philadelphia Museum of Art. “Philadelphia has rightfully earned its place as one of the greatest cities in the world.” Greenberger says.
1.We can learn from Paragraph 1 that Philadelphia ________.
A. is known for many America’s firsts
B. has been famous as a World Heritage City
C. has the best American hospital
D. has contributed a lot to the global economy
2.In Paragraph 2, Michael Nutter is talking about ________.
A. the World Heritage City
B. the significance of the city’s selection
C. the history of Philadelphia
D. the contributions of the city
3.What opinion does Alan Greenberger hold?
A. It’s easy for the city to win the honor.
B. The honor will bring the city a better future.
C. It won’t be long before the city takes off.
D. The city really deserves the honor.

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 not 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.
1.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.
2.Choset believes that his invention _________.
A.can be attached to an electronic arm
B.can be used by hobbyists in model airplanes
C.can find victims more quickly than a sniffer dog
D.can sense its way as well as its operators
3.By saying "We needed them yesterday" (paragraph 7), Stover means that snake-like robots ________.
A.could help handle the aftermath of Hurricane Katrina
B.should have been put to use in past rescue work
C.helped rescuers search flooded houses yesterday
D.were in greater need yesterday than today
4.What is the text mainly about?
A.Snake-like robots used in industries.
B.Snake-like robots made to aid in rescues.
C.The development of snake-like robots.
D.The working principles of snake-like robots.
