Passage TwoIMPATIENCE has been around for a long time. There is nothing new about people losing their patience while stuck in traffic or waiting in line. But some experts believe that people are less patient today than in the past-and for reasons that might surprise you.Some analysts suggest that in recent years many people are less patient because of technology. They suggest that “digital technology, from cellphones to cameras to email to iPads, is changing our lives. The instant results we get from this technology have in turn increased our desire for instant gratification in other aspects of our lives.”Psychologist Jennifer Hartstein makes some observations. She explains that “we have become an immediate satisfaction culture, and we expect things to move quickly, efficiently and in the way we want. When that doesn’t happen, we tend to become increasingly frustrated and unsatisfied.Some believe that e-mail is losing popularity and could soon become outdated. Why? Because many people who send messages do not have the patience to wait hours, or even minutes, for a response. Also, with e-mails, as with letter writing, introductory and concluding greetings are often expected. But many people consider such formalities（客套）to be boring and time-consuming. They prefer instant messaging。 Many people do not take the time to proofread what they put in writing. As a result, letters and e-mails contain numerous grammatical and spelling errors.The thirst for immediate results is not limited to the digital communication. People seem to be losing their ability to wait in other areas of life. For instance, do you ever find yourself talking too fast, eating too fast, driving too fast, or spending money too fast? The few moments it takes to wait for an elevator to come, for a traffic light to change, or for a computer to start may seem like too long a time. According to the first paragraph, people ________.

Passage ThreeScientists measured the ipact that people have on the enviroment using a term called carbon “footprint.” That footprint reflects the amount of carbon dioxide that is emitted(排放)into the atmosphere as a result of someone’s daily activities. Carbon footprints tend to be low for cith dwellers (城镇居民). Living in a suburb outside a city, however, can tern that footprint into a bootpring.Energy researchers Christopher Jones and Daniel Kammen calculated carbon footprints for people in every zip code across the United States. People living in city centers had small footprints, the researchers found. “It is much easier to have a low carbon impact if your home is close to where your work, shop and play,” explain Jones. Living within walking or biking distance cuts back on the amount of carbon dioxide associated with moving people by cars. And cities with extensive bus and subway networks allow people to travel great distances while keeping releases of climate-altering green house gases low.Not everyone can afford to live in the city, however. And not everyone wants to. Rings of suburbs have popped up around major cities across the world. Suburbs offer more space, allowing people to build larger homes. Suburbs may offer better schools for a family’s kids. But those homes are typically well beyond walikg distance from where their owners work, play and learn. So people who live in suburbs often drive long distances.The new findings are an important contribution to climate research, says Matthew Kahn, an enviromental economist at the University of California, who was not involved with the study. Kahn would like to see the analysis applied to other parts of the world – Europe, India and China, for instance. That would give scientists a better feel for how culture might mix with location to influence our carbon footprints. “Footprint”refer to the amount of carbon dioxide released by ________.
