If you want to keep healthy, you should have good habits. What is a habit? It is something we do very often. We don't even think when we do it. It has become a part of our lives. "Early to bed, early to rise makes a man healthy, wealthy and wise." This is an old English saying. Do you know what it means? It means that we must go to bed early at night and get up early in the morning. If we do, we shall be healthy, rich and clever. Is this true? Perhaps it is. We know the body must have enough sleep. Boys and girls need eight or nine hours' sleep every day. Some people go to bed late at night and get up late in the morning. This is a very bad habit. Then you will not think or do your work well. Of course, you can't be healthy, wealthy or wise. When we get up early in the morning, we can go out and do morning exercises. Exercise means doing things with the body. Walking, running jumping, swimming, and playing ball games are all exercise. If we don't exercise, our body will become weak. Exercise helps the blood to move around inside our body. Blood takes food to all parts of our body. Our body also needs air to breathe. Without air, we will die. We must have lots of clean fresh air if we want to be healthy. That is why many people like to go out to do morning exercise. How long should young boys and girls need to sleep a day? A) More than ten hours B) Over eleven hours. C) Less than seven hours. D) Eight hours or so.

By the mid-nineteenth century, the term "icebox" had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns , and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1861-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half of the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, a precursor of the modern fridge, had been invented. Making an efficient icebox as not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary . The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping up the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation and circulation needed for an efficient icebox. But as early as 1803, and ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool. What can we infer from the text? A) Thomas Moore is the inventor of modern fridge B) The butter produced by Thomas Moored is better in quality than other famers' C) Knowledge of the physics of heat plays an important part in inventing a good icebox D) Before 1880, most of the sold ice was used for family use.

Q: One day I took several pairs of shoes to the shoemaker to be mended. After a week I went to take them back. Four months later, my husband and I were invited to dinner. I took out a pair of shoes. I hadn't worn them since they were mended. I put one shoe on my right foot, and then I put the other on my left. But I felt that the other one was on the wrong foot. I took both shoes off for a closer look. They were nearly the same style , color and size, but each was for the right foot. Then I thought of the shoemaker. Though I was sure he wouldn't remember me after such a long time, I called him. "Thank goodness you called me at last!" He said happily. "An angry woman has been troubling me for months!" How many pairs of shoes did the woman take to the shoemaker to be mended? A) One shoe. B) Two pairs of shoes. C) Only three shoes. D) Some pairs of shoes.

Q: The right to pursue happiness is issued to us all with our birth, but no one seems quite sure what it is. A holy man in India may think that happiness is in himself. It is in needing nothing from outside himself. In wanting nothing, he lacks nothing. We westerners, however, are taught that the more we have from outside ourselves, the happier we will be, and then we are made to want. We are even told it is our duty to want. Advertising, one of our major industries, exists not to satisfy these desires but to create them--and to create them faster than any man's money in his pocket can satisfy them. Here, obviously someone is trying to buy the dream of happiness and spending millions upon millions every year in the attempt. Clearly the happiness-market is not running out of customers. I doubt the holy man's idea of happiness, and I doubt the dreams of the happiness-market, too. Whatever happiness may be, I believe, it is neither in having nothing nor in having more, but in changing--in changing the world and mankind into pure states. To change is to make efforts to deal with difficulties. As Yeats, a great Irish poet once put it, happiness we get for a lifetime depends on how high we choose our difficulties. Robert Frost, a great American poet, was thinking in almost the stone terms when he spoke of "the pleasure of taking pains." It is easy to understand. We even demand difficulty for the fun in our games. We demand it because without difficulty there can be no game. And a game is a way of making something hard for the fun of it. The rules of the game are man-made difficulties. When the player ruins the fun, he always does so by refusing to play by the roles. It is easier to win at chess if you are free, at your pleasure, to cast away all the rules, but the fun is in winning within the rules. The same is true to happiness. The buyers and sellers at the happiness-market seem to have lost their sense of the pleasure of difficulty. Heaven knows what they are playing, but it seems a dull game. And the... According to the passage, which of the following is right? A) The Indian holy man is much happier than westerners. B) The westerners understand happiness better than the Indian holy man. C) There is no fun without playing by the rules. D) Both the eastern weakness and western weakness are for the same reason.
