Plants take water from the ground through their roots. They take a gas called carbon dioxide (CO2) from the air. Plants use sunlight to turn water and CO2 into glucose(葡萄糖).Glucose is a kind of sugar. Plants use glucose as food for energy to grow. The way plants turn water and CO2 into glucose is called photosynthesis (光合作用).That means “putting together with light .” A chemical called chlorophyll helps make photosynthesis happen. Chlorophyll is green. It gives plants their green colour. As summer ends and autumn comes, the days get shorter and shorter. This is how the trees “know” to begin getting ready for winter. During winter, there is not enough light or water for photosynthesis .The trees will rest, and live on the food they have stored during the summer. They begin to close their food-making factories. The green Chlorophyll disappears from the leaves. Then, we begin to see yellow and orange colours. A few of these colors stay in the leaves all the time. We just can’t see them in the summer, because they are covered up by the green Chlorophyll. Red and purple colors we see in leaves are made mostly in the autumn. In some trees, like maples, glucose is stored in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into red. The brown color of trees like oaks is made from wastes left in the leaves. 74. The underlined word “chlorophyll” in the first Para means in Chinese. A 叶绿素 B 氧气 C 胡萝卜素 D 蛋白质 75.

You may even have entered the shop just to find a shelter from a sudden shower. Whatever the reason, you can soon totally unaware of your surroundings. You soon become interested in some books or others, and usually it is only much later that you realize you have spent too much time there and have to rush off to keep some forgotten appointment. This chance to escape the realities of everyday life is the main attraction of a bookshop. A music shop is very much like a bookshop. You can walk around such a place to your heart's content. If it is a good shop, no assistant will come up to you with the greeting "Can I help you?" You needn't buy anything you don't want. In a bookshop an assistant should remain in the background until you have finished reading. Then, and only then, are his services necessary. Once a medical student had to read a textbook which was far too expensive for him to buy. He couldn't borrow it from the library and the only copy he could find was in a certain bookshop. Every afternoon, therefore, he would go along to the shop and read a little of the book at a time. One day, however, he was disappointed to find the book missing from his usual place. He was about to leave, when he noticed the owner of the shop beckoning to him. Expecting to be told off, he went towards him. To his surprise, the owner pointed to the book which was tucked away in a corner. "I put it there in case anyone tries to buy it !"He said, and left the delighted student continuing his reading. 78.According to the passage the main attraction of a bookshop is that ________.

Another example of uniformity(一致)is in habits and ways of living.From Boston to Los Angeles it is as far as from France to Central Asia, and from east to west there are five time zones; but everywhere people get up and go to bed at about the same time, eat the same kind of food, buy in the same kind of shops, work and rest at the same time of the day and have the same pattern of holidays.In most of the things that matter there is less difference between rich people and ordinary people or between town and country, than in any single European nation.
