Babies love chocolate(巧克力)and sometimes they also eat the paper around it.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 can we also eat wood and paper?
　　Scientists(科学家)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 sea plants,then bigger 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(奶酪). And they can make it without the help of animals.It is very good food too.Now they have begun to say：“We make our paper from wood. We can also make food from wood.”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(喂)them to your cat. One day,soon,they will be on your plate. There is nothing for a good story for breakfast
