Obviously, in doing this no fuel is used in traveling to and from a conference, and less work time is taken up in attending a conference. Any material to be used during Web conferencing is simply ed to all the participants before the conference. Participants can then either choose to print material or read it on screen. This not only saves paper but also greatly reduces mailing costs for the business. As a conference hall or business center isn’t being used, it means that the only power that is used is the power used by the participants’ personal puters. Similarly conference anizers don’t have to arrange for food or overnight acmodation(住处 )for participants of their conferences. All this means that less energy is used. Often in business some panies actively choose to do business with other panies that do many things to reduce their negative impact on the environment.

D Cat has bright future By day he is just a normal cat but when the lights go out, he glows in the dark. Scientists have geically modified a cat as part of an experiment that could lead to treatments for diseases. Named Mr. Green Genes, he looks like a sixmonthold cat but, under ultraviolet(紫外线的 )light, his eyes, gums(牙龈 )and tongue glow green. That is the result of a geic experiment at the Audubon Center for Research of Endangered Species in New Orleans, US. Mr. Green Genes is the first fluorescent(荧光的 )cat in the US and probably the world, said Betsy Dresser, the center’s director. The researchers made him so they could learn whether a gene could be introduced harmlessly into a cat’s geic sequence. If so, it would be the first step in a process that could lead to the development of ways to treat diseases via gene therapy. The gene, which was added to Mr. Green Genes’ DNA, has no effect on his health, Ms. Dresser said. Cats are ideal for this project because their geic makeup is similar to that of humans, said Dr Martha Gomez, a scientist at the center. To show that the gene went where it was supposed to go, the researchers settled on one that would glow. The gene“is just a marker”, said Leslie Lyons, an assistant professor at the University of California, Davis. Lyons is familiar with the center’s work. “The glowing part is the fun part, ”she said.

What does the underlined phrase“settled on”most probably mean in Paragraph 9? A. killed B. chose C. took D. raised 35. From the passage we can see that . A. the cat named Mr. Green Genes can glow when it is dark . Green Genes was made by researchers to treat diseases C. Mr. Green Genes is the second fluorescent cat in the world D. Mr. Green Genes is a cat of。
