By day he is just a normal cat but when the lights go out, he glows (发光) in the dark.

Scientists have genetically modified (更改) a cat as part of an experiment that could lead to treatments for diseases.

   Named Mr. Green Genes, he looks like a six-month-old cat but, under ultraviolet (紫外线的) light, his eyes, gums (牙龈) and tongue glow green. That is the result of a genetic 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 genetic sequence (次序).

   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 (治疗).

   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 genetic 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.

   Glowing creatures made international news earlier this month when the Nobel Prize in Chemistry was awarded to three scientists who had discovered the gene through their work with jellyfish (水母).

By choosing to let go of the past, we sweep out all the ashes that weigh us down and affect every aspect of our health, and our peace of mind.

  My friend Jean was divorced after a thirty-year marriage that produced three daughters, one son and eight grandchildren. Because she actually raised them single-handedly, Jean was hurt and angry that the children didn't take her part after the divorce. For months she refused to attend any family celebration to which her former husband Jim was invited. When I reasoned that her children’s understanding of the relationship with and between the parents was probably altogether different from hers, she stuck to the belief that she was right.

  One day Jean called in tears. “Saturday is my granddaughter's birthday, and I want to be with her, but I can’t bring myself to face my former husband.”  “Jim isn't the problem,” I said gently, “it's false pride. Instead of holding on to the painful past, which is over and done, let the feelings go and get on with your life. You're depriving yourself of the joy of sharing in these important occasions, while Jim feels free to experience them. Tell me, would you rather be right, or be happy?”

  That must have done the trick because when Saturday arrived, Jean appeared at her daughter's home carrying her famous chocolate-chip cookies and a beautiful birthday

cake.

How great it feels to let go! And the more we practice the art of letting go of all negativity, the better able we become to devote our thoughts, our time, and our energy to living joyfully in the present, what ever age we happen to be.

   A. Jim did very little to bring up the children during their marriage.

   B. The writer thought Jean and Jim shouldn't have divorced.

   C. The children were on their father's side and didn't invite Jean to any family celebration.

   D. Jean had been too tough on Jim before they divorced.

The underlined phrase “depriving yourself of” is closest in meaning to ____ .

   A. persuading yourself to get              B. taking away from yourself

In the writer's opinion, ____.

A. Jean and Jim should be remarried

B. a broken family could live together in peace
