My cat enjoys a meal of good, thick paper, old letters, for example. She doesn’t like newspapers very much.Of course, the best paper comes from wood. Wood comes from trees and trees are plants. Vegetables and fruit are plants too, and we eat a lot of them. So we can also eat wood and paper.Scientists say, “All food comes in some way from plants.” Well, is that true? Animals eat grass and grow fat, then we eat their meat. Little fish eat little seaplants, then bigger fish swim along and eat them. Chickens eat lots of grass and give us meat. Think for a minute. What food does not come from plants in some way?Scientists can do wonderful things with plants. They can make food just like meat and cheese. And they can make it without the help of animals. It is very good food, too. Now, they begin to say, “We make our paper from wood, and we can also make food from wood. The next thing is not very difficult.”What is the next thing? Maybe it is food from paper. Scientists say, “We can turn paper into food. It will be good, cheap food too, cheaper than meat or fish or eggs.”So please keep your old books and letters (Don’t feed them to your cat). One day, soon, they will be on your plate.

A bolt of lightning is six times hotter than the surface (表面) of the sun and gives out 30, 000 amps of electricity (电). It can travel at 100, 000 kilometers per hour and has the ability to hit a target up to 40 kilometers away. About 1,000 people around the world are killed by lightning every year.Only about ten percent of people struck (击中) by lightning will actually die, but the others are actually very badly injured (受伤), with burns, broken bones, blindness, deafness, paralysis, or memory loss. However, when the electricity passes through their brains (大脑), it can occasionally have unusual and even positive effects (积极作用). Some blind (瞎的) people have got their sight back after being struck by lightning. One woman said a psychological test showed her intelligence (智力) had greatly improved (提高) and one man said he could no longer feel cold at all and could go out in temperature below zero in just a T-shirt!So what should you do to stay safe in a thunderstorm? The most important rule is to stay inside, but do not go near phones, electrical appliances, plumbing or water. If you are struck outside, do not take shelter under a tree. Instead, roll (卷) yourself up into a ball on the ground as small as possible. And do not think it has to be raining in order for lightning to strike.Strangely, lightning seems to prefer (偏爱) some people to others.
