How to Survive Being Stuck in a Lift

Being stuck in a lift, also known as an elevator, can sometimes be scary, especially if you are a fan of those kinds of movies which have a lot of elevator tragedies. You may think being stuck in an elevator in real life is not like in the movies.1.

Remain calm and do not panic! You may have heard of this a lot of times and it is true that panicking will do you no good. 2.

Press each of the floor buttons one by one. Then, try the “doors open” button. If none of the buttons works, the lift is broken, and you need to let someone know about it.

See if your phone has any reception or Internet. 3. If you have WiFi connection, contact a family member or friend. Don’t forget to tell them what the address is of the building and possibly which elevator you are stuck in. If your phone is not available, the following tips can help you.

Look through the gap between the doors of the lift. If you can see light between the doors, the lift has stopped near a floor, and you should be able to shout for help and be released. Do not try to force the doors open yourself. If you can’t see light between the doors, the lift has stopped between floors, and no one will be able to let you out if you scream for help. Look for an emergency telephone. If there is no telephone, press the alarm button repeatedly. 4.

5.If you have waited for more than half an hour and nobody has come to get you out, shout and bang the inside walls of the lift. If no one is responding to you, then you’ll have to accept that you will be in the lift overnight. If this happens, make yourself as comfortable as possible to save your energy. By morning, the building should be full again. You can try to get some help then.

A.It will cause you not to be able to think clearly.

B. Check the time.

C. Eventually, someone should hear you and get help.

D. Here are some tips to help you survive.

E. However, it is still a vital thing to know how to survive if it ever happens to you.

F. Use your watch.

G. If you do have reception, call emergency services.

    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.

4.What can be a suitable title for the text?

A. Why Some Cities Are Losing People but Getting Wealthier

B. How Fast Job Growth Is Related to Population Growth

C. How Less-crowded Cities Plan Their High-tech Economy

D. Why Some Cities Are Suffering From a Shrinking Population
