The report from NHTSA suggests that A. fewer people were injured in crosswalks B. crosswalk safety has been greatly improved C. much has been done to reduce traffic accidents D. pedestrian deaths in crosswalks remain a serious problem E All too often, a choice that seems sustainableturns out on closer examination to be problematic. Probably the best example is the rush to produce ethanol for fuel from corn. Corn is a renewable resource -you can harvest it and grow more, almost limitlessly. So replacing gas with corn ethanol seems like a great idea. One might get a bit more energy out of the ethanol than that used to make it, which could still make ethanol more sustainable than gas generally, but that’s not the end of the problem. Using corn to make ethanol means less corn is left to feed animals and people, which drives up the cost of food. That result leads to turning the fallow land –including, in some cases, rain forest in places such as Brazil-into farmland, which in turn gives off lots of carbon dioxide (CO) into the air. Finally, over many years, the energy benefit from burning ethanol would make up for the forest loss. But by then, climate change would have progressed so far that it might not help. You cannot really declare any practice “sustainable until you have done a complete life-cycle analysis of its environmental costs. Even then, technology and public keep developing, and that development can lead to unforeseen and undesired results. The admirable goal of living sustainably requires plenty of thought on an ongoing basis. 查看更多

Cities alarmed by deaths and injuries of pedestrians are taking efforts to make crosswalks safer for people on foot, especially seniors and children who need more time to cross streets.

  A pedestrian is killed in a traffic accident in the USA every 110 minutes; one is injured every nine minutes, according to official data. Crosswalks can be especially dangerous for the elderly. Among people 70 and older, 36% of pedestrian deaths in 2006 occurred in crosswalks, compared   with 21% of those younger than 70, according to the Insurance Institute for Highway Safety.

   The Federal Highway Administration(FHWA) advise that next year states increase by nearly 15% the amount of  time traffic lights provide for pedestrians to cross the street after the flashing orange hand appears.

FHWA spokesman Doug Hecox says reasons for the change include an aging population that needs more time to cross, health-conscious Americans walking more, children encouraged to walk to prevent getting overweight and high gas prices pushing people to walk instead of drive.

Pedestrian deaths went down by 12% from 5,449 in 1996 to 4,784 in 2006, Bur among those in 2006, 471 were killed in crosswalks, down slightly from 488 ten years earlier, the National Highway Traffic Safety Administration(NHTSA) says.

53. Which of the following is true according to the text?

A. Among 100 pedestrian deaths there were 21 people younger than 70

B. Old people are more likely to meet with accidents happened per hour.

C. Traffic accidents killed more old people than young people

D. About seven traffic accidents happened per hour.

54. What is FHWA’s suggestion to states?

A. Fixing more traffic lights

B. Providing more crosswalks

C. Giving pedestrians more time to cross streets.

D. Drivers don’t give way

56. The report from NHTSA suggests that         

A. fewer people were injured in crosswalks

B. crosswalk safety has been greatly improved

C. much has been done to reduce traffic accidents

D. pedestrian deaths in crosswalks remain a serious problem
