Emotional reactions as well as logical thought processes affect the behavior of most people. "The burnt child fears the fire" is one instance; another is the rise of figures like Hitler. Both these examples point up the fact that attitudes come from experience. In the one case the experience was direct and impressive; in the other it was indirect and gradual. The classroom teacher in the elementary school is in strategic position to influence attitudes. This is true partly because children acquire attitudes from those adults whose word they respect. Another reason it is true is that pupils often search somewhat deeply into a subject in school that has only been touched upon at home or has possibly never occurred to them before. To a child who has previously acquire little knowledge of Mexico, his teacher's method of handling such a unit would greatly affect his attitude toward Mexicans. The teacher can develop proper attitudes through social studies, science matters, the very atmosphere of the classroom, etc. However, when children come to school with undesirable attitudes, it is unwise to attempt to change their feelings by criticizing them. The teacher can achieve the proper effect by helping them obtain constructive experience. To illustrate, first-grade pupils, afraid of policemen will probably change their attitudes after a classroom talk with the neighborhood officer in which he explains how he protects them. In the same way, a class of older children can develop attitudes through discussion, research, outside reading and all-day trips. Finally, a teacher must constantly evaluate her own attitudes, because her influence can be harmful she has personal prejudices. This is especially true in respect to controversial issues and questions of which children should be encouraged to reach their own decisions as result of objective analysis of all the facts. Question: According to the author, teachers may have great influence on children's attitudes because _ . Options: A: they can use marks to judge students B: they can control students' behavior C: they may judge a student from their own likes and dislikes D: their words are usually respected by the children

At 17, his father tired to persuade him not to become a mathematician because he may lead a poor life being a mathematician, and so von Neumann agreed to study chemistry as well. In 1926, at 23, he received a degree in chemical engineering and a Ph.D. in mathematics. From then on, mathematics provided well enough for him, and he never had to turn to chemistry. In 1930, von Neumann visited Princeton University for a year and then became a professor there. His first book was published in 1932. In 1933, the Institute for Advanced Study was formed, and he became one of the 6 full-time people in the School of Mathematics(Einstein was one of the others) World War II hugely changed von Neumann's areas of interest. Until 1940 he had been a great pure mathematician. During and after the war, he became one of the best mathematicians who put mathematics theories into practice. During the last part of the war he became interested in computing machines and made several fundamental contributions After the war, von Neumann continued his work with computers, and was generally very active in government service. He received many awards, was president of the American Mathematical Society and was a member of the Atomic Energy Commission. He died in 1957 of cancer. Von Neumann made several great contributions and any one of them would have been enough to earn him a firm place in history. He will be remembered as one of the greatest minds of the 20th century. Von Neumann really was a legend in his own time, and there are a number of stories about him. His driving ability is a part of his legend. He reported one accident this Way: "I was driving down the road. The trees on the right were passing me in an orderly fashion at 60 miles per hour. Suddenly one of them stepped in my path." Question: von Neumann published his first book at the age of _ Options: A: 23 B: 26 C: 29 D: 32

Q: Read the article and select the best answer. Article: Astronauts aboard the space station celebrated a space first on Wednesday by drinking water that had been recycled from their urine , sweat and water got from air. They said "cheers," clicked drinking bags and toasted NASA workers on the ground. The urine recycling system is needed for astronaut stations on the moon and Mars. It also will have NASA money because it won't have to ship up as much water to the station by space shuttles or cargo rockets. Besides, it's important as the space station is about to expand from three people living on board to six. The recycling system had been brought up to the space station last November by space shuttles Endeavour, but it couldn't be used until samples were tested back on earth. So when it came time to actually drink up, NASA made a big deal of it. The three-man crew stood holding their drinks and congratulated engineers in two NASA centres that worked on the system. "This is something that had been the stuff of science fiction," American astronaut Michael Barratt said before taking a small mouthful. "The taste is worth trying." The new system takes the combined urine of the crew from the toilet, moves it to a big tank, where the water is boiled off, and the vapor is collected. The rest of the urine is thrown away. Then the water vapor is mixed with water from air, and then it goes through filters . When six crew members are aboard it can make about six gallons from urine in about six hours. "Some people may find the idea of drinking recycled urine distasteful, but it is also done on earth, but with a lot longer time between urine and the tap," said Marybeth Edeen, the space station's national lab manager. The technology NASA developed for this system has already been used for quick water purification after the 2004 Asian tsunami. Question: According to the text, the recycling system is important because _ . Options: A: it makes traveling to the moon for the average person possible B: with it NASA won't need to ship any water up the space station C: it can help meet the need for more water after the crew is expanded D: it protects the environment in space by reducing the amount of waste
A: C
