[单项选择]A report on a new software that enables eyes to do the typing appears in Wednesday’s edition of the journal Nature. Replacing a keyboard or mouse, eye- scanning cameras mounted on computers have become necessary tools for people without limbs or those affected with paralysis. The camera tracks the movement of the eye, allowing users to "type" on a virtual keyboard as they look at the screen. And now, researchers from the Cavendish Laboratory at Cambridge University say they have developed software that replaces the standard QWERTY (标准的传统键盘) keyboard layout with one that is nearly twice as efficient, more accurate and easier on the eyes. Called Dasher, the prototype program taps the natural gaze of the eye and makes predictable words and phrases simpler to write. Any off-the-shelf camera capable of scanning eye movement can be used with Dasher, though the person must sit fairly still during the interaction.

[单项选择]Big Polluters Told to Report Emissions
The new rules would require 10,000 industrial sites and suppliers of petroleum products to submit the data beginning in 2011. Suppliers of fossil fuels(石油)will be asked to estimate how much carbon dioxide(二氧化碳), methane(甲烷) and other greenhouse gases are emitted when the fuels are burned by businesses and consumers in buildings and cars, the agency said.
The E. P. A. said it had no firm estimate on how many businesses had the training and systems in place to report on their emissions. But a large percentage of those covered by the new regulations are already required to report emissions under other programs sponsored by the agency, it said.
