任務(wù)型閱讀。閱讀下面的短文，根據(jù)短文內(nèi)容完成表格中所缺信息，每空一詞。（10分）
Much of our good health depends on the cooperation（協(xié)同作用） between substances（物質(zhì)）. When they work together ,chemical reactions（反應(yīng)） take place smoothly. Body systems are kept in balance. Some of the most important helpers in the job of good health are the substances we call vitamins.
Vitamin A is needed to produce a light –sensitive substance in the eyes. People who do not get enough vitamin A can’t see well in the dark. The best source(來源) of vitamin A is fish liver oil. It is also found in the yellow part of eggs. What’s more, squash, sweet potatoes, carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A.
Vitamin B-1 is also called thiamine. It changes starchy foods into energy. It also helps the heart and nervous system work smoothly. Without it, we would be weak and would not grow. Thiamine is found not just in whole grains like brown rice, but also in other foods. These include beans and peas, nuts and meat and fish.
VitaminB-12 is needed so folic acid can do its work. Together , they help produce red blood cells. Without them, a person suffers from anemia(貧血)。VitaminB-12 is found naturally in foods such as eggs, meat, fish and milk products.
Vitamin C is necessary for strong bones and teeth, and for healthy blood vessels. It also helps wounds heal quickly. The body stores very little Vitamin C. so we must get it very day in foods such as citrus, tomatoes and uncooked cabbage.

Values join us together and set us apart. Today, our society has a terrible lack（缺乏）of values. Here are some social values that everyone needs.
◆Respect
Respect means to respect（尊重）others in everyday life. Even if you are against a person, it is important to have respect. It is this respect that makes us human. Without this respect, we become  animals. We need to respect our friends for our friendships. We even need to respect our enemies, because they help us to grow up and be stronger. Respect is one of the crucial values in a relationship.
◆Love
Love is everything. With love in our hearts, we feel no need to hurt another. With love in our hearts, we will pay more attention to the similarities in opinions rather than the disagreement. If we want others to be good to us, we need to be good to them. After all, we give love to get love, right?
◆Loyalty
People often forget the meaning and importance of loyalty（忠誠）. Loyalty is necessary for people to believe in each other. In no matter what kind of relationship, we need to believe in each other so that we can work together towards the same goal.
◆Honesty
Honesty is to show other people who we really are. Honesty helps us do better, because it makes us realize our problems and find ways to solve them. It is this honesty, that will make others help you out, not because you need it. But, because they have problems too, which you can help out with.
