Passage 3 Since World War II, there has been a clear trend, especially among the growing group of college students, toward early marriage. Many youths begin dating in the first stages of adolescence (青春期), “go steady” through high school, and marry before their formal education has been completed. However, emotional maturity is no respecter of birthdays; it does not arrive automatically at twenty-one or twenty-five. Some achieve it surprisingly early, while others never do, even at the age of seventy. Many students are marrying as an escape from their own personal problems of loneliness. However any marriage entered into as an escape cannot prove entirely successful. The sad fact is that marriage seldom solves one’s problems; more often, it merely makes them worse. Furthermore, it is doubtful whether the home as an institution is capable of carrying all that the young are seeking to put into it. Young people correctly understand that their parents are wrong in believing that success is the ultimate (最终的) good, but they mistakenly believe that they themselves have found the true center of life’s meaning. Their expectations of marriage are essentially unrealistic, and therefore incapable of fulfillment. They want too much, and disillusionment (幻想破灭) is often sure to follow. Shall we, then, think early marriages are bad? One cannot draw the conclusion that all early marriages are bad or all later ones are good. Satisfactory marriages are determined not by age, but by the emotional maturity of the partners. Therefore, each case must be judged on its own merits. If the early marriage is not an escape, if it is entered into with relatively few illusions (幻想) or false expectations, and if it is economically practical, why not? Good marriages can be made from sixteen to sixty, and so can bad ones. Since World War II people tend to marry early for the following reasons except that ________.
A、they begin dating at an early age
B、they want to get rid of loneliness
C、they become physically mature early
D、they achieve emotional maturity early
A、until; when
B、not until; when
C、until; that
D、not until; that
A、extra
B、long
C、essential
D、beautiful
"The burnt child fears the fire" is one instance: another is the rise of dictators like Hitler. Both these examples also point out the fact that attitudes stem from experience. In the one case the experience was direct and impressive: in the other it was indirect and accumulative. The Nazis were filled largely with the speeches they heard and the books they read.
The classroom teacher in the elementary school is in a strategic position to influence attitudes. This true partly because children acquire attitudes from those adults whose words they respect.
Another reason, it is true that pupils often study somewhat deeply a subject in school that has only been touched upon at home or has possibly never occurred to them before. To a child who had previously acquired little knowledge of Mexico, his teacher's method of handling such a unit would greatly affect his attitude toward Mexicans.
The media which the teacher can develop healthy attitudes are innumerable. Social studies(with special reference to races, beliefs and nationalities), science matters of health and safety, the very atmosphere of the classroom, these are a few of the fertile fields for the education of proper emotional reactions.
However, when children come to school with undesirable attitudes, it is unwise for the teacher to attempt to change their feelings by scolding them. She can achieve the proper effect by helping them obtain constructive experiences.
To illustrate, first grade pupils' afraid of policemen will properly alter their attitudes after a classroom chat 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 oven attitudes, because her influence can be harmful if she has personal prejudices. This is especially true in respect to controversial issues and questions on which children should be encouraged to reach their own decisions as a result of objective analysis of the facts.
The author writes this passage primarily in order to show us that______.
A.attitudes affect our actions
B.teachers play a significant role in developing or changing pupils' attitudes
C.attitudes can be changed by some classroom experiences
D.by their attitudes teachers affect pupils' attitudes unintentionally
