Life could not go on if there were noplants. 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 plants.Flowering plants can make seeds. 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(胚芽). Spores are 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 are all on wet and shady places, they usually grow into new plants.6. The main idea of the first paragraph is that ______.A. plants are important for lifeB. plants cannot grow without airC. there are many plants in the worldD. we can not live without water7.

Even since she was a young girl, she has wanted to become a teacher. She has taught eight years now and hasn’t changed her mind.After she graduated from high school, she went on to college. Four years later, she received her bachelor’s degree (B A) in English and her teaching certificate（证书）. Then she went to teach in the secondary schools of her state. In the summers, Mrs. Blake takes more classes; she ho pes to get a master’s degree (M A). With an MA, she will receive a higher salary and if possible, she hopes to get a doctor’s degree as well.The school day at Mrs. Blake’s high school, like that in many high schools in the United States, is divided into one hour each. Mrs. Blake must teach five of theseperiods. During her free period, which for her is from 2 to 3 P.M. , Mrs. Blake must meet with parents, make out examinations, check assignments at all, Mrs. Blake works continuously from the time she arrives at school in the morning till the time she leaves for home late in the afternoon.11.

It’s hard work and it makes you short of breath. To fly over the channel takes only twenty minutes as long as you’re not held up at the airport, but it’s an expensive way to travel. Y ou can tr avel by hovercraft (气垫船)if you don’t mind the noise and that takes forty minutes. Otherwise, you can go by boat, if you remember your sea-sickness pills. All these means of transport have their problems, and the weary(厌烦的)traveler often dreams of being able to drive to France in his own car. “Not possible, you say. Well, wait a minute. People are once again considering the idea of a channel tunnel or bridge.”This time, the great London Council(议会)is looking into the possibility of building a channel link straight to London. A bridge would cost far more than a tunnel, but you would be able to by rail or by car on a bridge, yet a tunnel would provide a rail link only.Why is this idea being discussed again? Is Britain realizing the need for links with Europe as a result of joining EEC? Well, perhaps, the main reason, though, is that a tunnel or bridg e would reach the twenty square kilometers of London’s discussed dockland(船坞). A link from London to the continent would stimulate(刺激) trade and revitalize(使重新具有活力)the port, and would make London a main trading center inEurope. With a link over the Channel, you could buy your fish and chips in England and be able to eat them in France while they are still warm!16.

The biggest country in Europe is France — except Russia, which is only partly in Europe. And the smallest one is San Marino （ 圣马力诺 ）, which is only twenty-three square miles.The people of France are similar to the people of Italy, Spain and Portugal, and their languages are almost alike. This is because long ago all these people spoke Latin, so the languages they speak today mainly come from Latin. Other people that are related to each other are the people from Britain, Germany, Austria, Holland and Norway. They speak languages called Germanic （日尔曼语）.The third big “ family in Europe are the Slavs （斯拉夫人）,of whom the most important are the Russians. There are also some other smaller groups in Europe.The British Isles are made up of England, Scotland, Wales, Ireland and various small surrounding islands. From the British Isles, not far across the English Channel is the next European country, France. It 's capital is Paris, which is a beautiful city on the River Seine. Traveling further from France, we 'llvisit Venice in Italy, a beautiful city of water. Holland is different from the other countries of Europe, because a good deal of the land used to be under the sea. If traveling to the most northern part of Europe, we ' ll trave （斯堪Ug 纳SCandinavia亚半岛 ） to Norway, which lies right beyond the Arctic Circle （ 北极圈 ）. 56.
