[简答题]Reading is a pleasure of the mind, which means that it is a little like a sport: your eagerness and knowledge and quickness make you a good reader. {{U}}Reading is fun, not because the writer is telling you something, but because it makes your mind work. Your own imagination works along with the author’s or even goes be-yond his. Your experience, compared with his, brings you to the same or different conclusions, and your ideas develop as you understand his.{{/U}} {{U}}Every book stands by itself, like a one-family house, but books in a library are like houses in a city.

The United States is a democracy, which means that the citizens run the government. Since we can’t all make the rules, we elect representatives—our president, vice-president, senators, congressmen, governors, and others who make the laws and govern our country based on the beliefs of the people. These elected officials help pass laws that reflect the interests of their constituents, the people who live within the areas they represent.

Cancer develops over a long time, which means that you have years——typically decades——in which to hinder or promote it. Researchers are finding that what you eat may interfere with cancer growth at various stages. For example, certain foods can block the chemicals that initate cancer. Antioxidants(抗氧化剂), found in some vitamins and minerals, can snuff out oxygen free radicls (氧自由基), substances that are thought to make cells more susceptible to cancer, and they can even repair some of the cellular damage that has been done. And some food—wheat bran(麦,糠) in particular—has been shown to shrink precancerous(癌症前期的) cells.
A recent review of 17 studies from 17 nations reveals that people who eat the most fruits and vegetables have about half the cancer raters of those who eat the least. In fact, some research suggests that frequent consumption of fruits and vegetables can cut the risk of lung cancer even in smokers.
