They used different parts of the plants—the roots, the leaves, the flowers, and the bark (树皮). Today, doctors have rediscovered more medicinal value of some plants. Let’s look at some examples. Foxglove is a common plant. People have used it to make the heart slow down. Recently, scientists have developed another drug from it. This new drug helps prevent other heart problems. In some areas, malaria (疟疾)has been a problem. Scientists have learned that the bark of a South American tree, the cinchona, can be made into a drug to prevent malaria.For a long time, the Chinese have known that a special plant, wormwood, can also fight malaria. Scientists have been working with it to develop new drugs against malaria. In Germany, some scientists have studied garlic (大蒜) for four years. They have found that it helps prevent the build-up of plaque(血小板) because too much plaque is bad for health. This very common plant continues to be studied. As we know, there are about 250,000 kinds of flowering plants in the world. Scientists have only studied little more than one percent of plants for their medicinal value. Maybe medicines for AIDS and cancer will be made from the other 99 percent. 　　1~2题完成句子;3题简略回答问题;4题给短文拟定一个标题;5题将文中画线句子译成汉语。 1.People used　　　　　　like the roots, the leaves, the flowers and the bark to make medicine. 2.People make the cinchona into a drug which can　 . 3.How many plants are mentioned in the passage 4. 5. 六、语法填空 Ch ... ...
