It is true that good writers rewrite and rewrite and then rewrite some more. But in order to work up the desire to rewrite, it is important to learn to like what you write at the early stage.
I am surprised at the number of famous writers I know who say that they so dislike reading their own writing later that they even hate to look over the publishers’ opinions. One reason we may dislike reading our own work is that we’re often disappointed that the rich ideas in our minds seem very thin and plain when first written down. Jerry Fodor and Steven Pinker suggest that this fact may be a result of how our minds work.
Different from popular belief, we do not usually think in the works and sentences of ordinary language but in symbols for ideas (known as ‘mentalese’ ), and writing our ideas down is an act of translation from that symbolic language. But while mentalese contains our thoughts in the form of a complex tapestry (织锦)，writing can only be composed one thread at a time. Therefore it should not be surprising that our first attempt at expressing ideas should look so simple. It is only by repeatedly rewriting that we produce new threads and connect them to get closer to the ideas formed in our minds.
When people write as if some strict critics (批评家) are looking over their shoulder, they are so worried about what this critic might say that they get stuck before they even start. Peter Elbow makes an excellent suggestion to deal with this problem. When writing we should have two different minds. At the first stage, we should see every idea, as well as the words we use to express it, as wonderful and worth putting down. It is only during rewrites that we should examine what we excitedly wrote in the first stage and check for weaknesses.

Now, we know that if we do not get enough vitamins, we are at risk of developing a number of diseases. As a result, vitamin supplements（补品），though expensive, are popular with people who worry that they are not getting enough vitamins from the foods they eat. But contrary to what many people think, medical experts have found little evidence that most supplements do anything to improve health or protect against disease.
In fact, medical experts warn that taking too many of some vitamins can be harmful. For example, too much vitamin E can cause bleeding. People should discuss what vitamins they take with their doctors, as some vitamins can produce harmful side effects when mixed with medicines.
Experts, however, do say that sometimes vitamins can help prevent disease. People who know they lack a particular vitamin should take vitamin supplements. Some older adults, for example, may not have enough vitamin B-twelve. This is because, as people get older, their body loses its ability to take it from foods. Also, people who spend much time inside may need some extra vitamin D as the skin makes this vitamin from sunlight.
Different vitamins are found in different foods. Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A. Vitamin B-twelve is found in green leafy vegetables and other foods, like fruits. Vitamin K can be found in pork products.
In fact, for most people, a balanced diet can ensure enough of the vitamins our bodies need. So, it is important for us to eat a mixture of foods every day to ensure that we get enough vitamins our bodies need.
