材料：戴高乐从1958年开始连续当了11年法国总统，他领导制定了《法兰西第五共和国宪法》，重新确立法国的政治体制。任内他把主要精力放在对外事务上。戴高乐支持发展核武器、制定泛欧洲外交政策、努力减少美国和英国的影响、促使法国退出北约、反对英国加入欧洲共同体、承认中华人民共和国，这一系列思想政策被称为“戴高乐主义”。

    1970年11月9日戴高乐因心脏病猝然逝世。蓬皮杜总统于次日向法国人民发表广播讲话：“戴高乐将军逝世了，法国失去了亲人。1940年，戴高乐将军拯救了我们的荣誉。1944年，他领导我们走向解放和胜利。1958年，他把我们从内战的威胁中救了出来，他使今天的法国有了自己的制度、独立和国际地位……让我们向法国保证，我们决不辜负我们所得到的教诲，愿戴高乐将军永远活在全国人民的心中。”

回答问题：

Many students in China are learning English. Some of these students are small children  Others are teenagers(青少年). Many are adults(成年人). Some learn at school, others study by themselves. A few learn English language over the radio, on television or in films. One must work hard to learn another language.
Why do all these people want to learn English? It is difficult to answer that question.  Many boys and girls learn English at school because it is one of their subjects. They study their own(自己的) language, Maths and English. Some people learn English because it is useful(有用的) for their work. Many people often learn English for their further studies, because at college or university(大学) some of their books are in English. Other people learn English because they want to read newspapers and magazines in English.

     Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.
     If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering(不开花的) plants.
      Flowering plants can make seeds(种子). The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit.
    Most non-flowering plants do not grow from seeds. They grow from spores(孢子). Spores are very, very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores fall on wet and shady(阴凉的) places, they usually grow into new plants.
