Eat to Live

A. meager diet may give you health and long life, but it’s not much fun — and it might not even be necessary. We may be able to hang on to most of that youthful vigor even if we don’t start to diet until old age.
Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse’s liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation won’t reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins.
Spindler’s team fed three mice a normal diet for their whole lives, and fed another three on half-rations. Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old — equivalent to about 70 human years.
The researchers checked the activity of 11,000 genes from the mouse livers,
A. To describe the influence of old age on mice.
B. To illustrate the effect of meager food on mice.
C. To tell us how mice’s liver genes behave.
D. To inform us of the process of metabolizing drugs.

If you are what you eat, then you are also what you buy to eat. And mostly what people buy is scrawled onto a grocery list, those ethereal scraps of paper that record the shorthand of where we shop and how we feed ourselves. Most grocery lists end up in the garbage. But if you live in St. Louis, they might have a half-life you never imagined: as a cultural document, posted on the Internet.
For the past decade, Bill Keaggy, 33, the features photo editor at The St. Louis Post-Dispatch, has been collecting grocery lists and since 1999 has been posting them online at www. grocerylists, org. The collection, which now numbers more than 500 lists, is strangely addictive. The lists elicit twofold curiosity-about the kind of meal the person was planning and the kind of person who would make such a meal. What was the shopper with vodka, lighte

[填空题]All of us who live a busy life may ask this question: how can I find time to read The answer may be 15 minutes a day at any time. No universal formula can be prescribed. Each of us must find our own 15-minutes period each day. It is better if it is regular.
The only requirement is the will to read. With it you can find the 15 minutes no matter how busy the day is. And you must have the book at hand. Not even seconds of your 15 minutes should be wasted when you start to read. Set the book out in advance. Put it into your pocket when you dress. Put another book beside your bed. Place one in your bathroom. Keep one near your dining table.
You can’t escape reading 15 minutes a day, and that means you will read half a book a week, 2 books a month, 20 a year, and 1,000 or more in a life time reading. It’s an easy way to become well read.
How to Find Time to Read
The suitable time may be (46) a day at any time.
It’ll be better if (47)
The only requirement
