[阅读理解]To say that the child learns by imitation and that the way to teach is to set a good example oversimplifies. No child imitates every action he sees. Sometimes, the example the parent wants him to follow is ignored while he takes over contrary patterns from some other example. Therefore we must turn to a more subtle theory than “monkey see, monkey do.”Look at it from the child’s point of view. Here he is in a new situation, lacking a ready response. He is seeking a response which will gain certain ends. If he lacks a ready response for the situation, and cannot reason out what to do, he observes a model who seems able to get the right result. The child looks for an authority or expert who can show what to do.There is a second element at work in this situation. The child may be able to attain his immediate goal only to find that his method brings criticism from people who observe him. When shouting across the house achieves his immediate end of delivering a message, he is told emphatically that such a racket is unpleasant, that he should walk into the next room and say his say quietly. Thus, the desire to solve any objective situation is overlaid with the desire to solve it properly. One of the early things the child learns is that he gets more affection and approval when his parents like his response. Then other adults reward some actions and criticize others. If one is to maintain the support of others and his own self-respect, he must adopt response his social group approves.In finding trial responses, the learner does not choose models at random. He imitates the person who seems a good person to be like, rather than a person whose social status he wishes to avoid. If the pupil wants to be a good violinist, he will observe and try to copy the techniques of capable players; while some other person may most influence his approach to books.Admiration of one quality often leads us to admire a person as a whole, and he becomes an identifying figure. We use some people as models over a wide range of situations, imitating much that they do. We learn that they are dependable and rewarding models because imitating them leads to success.1. The statement that children learn by imitation is incomplete because ___________.A) they only imitate authorities and expertsB) they are not willing to copy their parentsC) the process of identification has been ignoredD) the nature of their imitation as form of behavior has been neglected.2. For a child the first element in his learning by imitation is ___________.A) the need to find an authorityB) the need to find a way to achieve the desired resultC) the need for more affection from his parentsD) the desire to meet the standards of his social group3. Apart from achieving his desired results, a child should also learn to ___________.A) behave properlyB) attain his goal as soon as possibleC) show his affection for his parentsD) talk quietly4. Children tend to imitate their models ___________.A) who do not criticize themB) who bring them unexpected rewardsC) whom they want to be likeD) whose social status is high5. “An identifying figure” (Lines 1-2, Para. 5) refers to a person ___________.A) who serves as model for othersB) who is always successfulC) who can be depended uponD) who has been rewarded for his success

[阅读理解]The Great Fire of London started in the very early hours of September 1666. In four days it destroyed more than three-quarters of the old city, where most of the houses were wooden and close together. One hundred thousand people became homeless, but only a few lost their lives. The fire started on Sunday morning in the house of the King’s baker(面包师) in Pudding Lane. The baker, with his wife and family, was able to get out through a window in the roof. A strong wind blew the fire from the bakery (面包房) into a small hotel next door. Then it spread quickly into Thames Street. That was the eginning. By eight o’clock three hundred houses were on fire. On Monday nearly a kilometer of the city was burning along the River Thames. Tuesday was the worst day. The fire destroyed many well-known buildings, old St Paul’s and the Guildhall were among them. Samuel Pepys, the famous writer, wrote about the fire. People threw their things into the river. Many poor people stayed in their houses until the last moment. Birds fell out of the air because of the heat. The fire stopped only when the King finally ordered people to destroy hundreds of buildings in the paths of the fire. With nothing left to burn , the fire became weak and finally died out. After the fire, Christopher Wren ,the architect , wanted a city with wider streets and fine new houses of stone. In fact, the streets are still narrow, but he did build more than fifty churches, and the new St Paul’s is among them. The fire caused great pain and loss, but after it London was a better place : a city for the future and not just of the past. 1.The fire began in ____. a hotel the palace Pudding Lane Thames Street 2.The underlined word “family” in the second paragraph means _____. home children wife and husband wife and children 3.It seems that the writer of the text was most sorry for the fact that______. some people lost their lives the birds in the sky were killed by the fire many famous buildings were destroyed the King’s bakery was burned down 4.Why did the writer cite (引用)Samuel Pepys ?

To give the reader a clearer picture of the fire. 5.How was the fire put out according to the text? The King and his soldiers came to help. All the wooden houses in the city were destroyed. People managed to get enough water from the river. Houses standing in the direction of the fire were pulled down.
