单选题. Learning is an essential process for living things to acquire necessary skills and behaviors. Scientists have already found that there is a critical period for learning in man and animals. Once the right time for learning a skill or a certain behaviors has passed, this skill or behavior can never be properly learned. That we speak our own language perfectly and the languages we learn later imperfectly also depends on learning this skill at the right time. The brain develops in such a way that it is ready to learn to speak between the ages of about ten months and ten years. Languages learned later are not spoken perfectly. The ability to speak a language is a mixed motor and sensory skill. It is necessary to hear all the sounds, the subtle differences between similar but not identical sounds, the rhythm and tone of the language. One has also to work tongue, throat, and lips to control breathing. All this has to be managed at one and the same time. From some time after birth until the age of six or seven, normal children all learn this perfectly, and without much difficulty they can learn two or even three languages at the same time, without confusing one with the other. But later, most of us cannot acquire this skill. We may learn to write and read the new language perfectly, but to acquire the right accent and the ability to speak so that no one can detect that the language is not our mother tongue hardly ever occurs. But those of us who still want to learn foreign languages after these early milestones have been passed need not worry, for though we may not learn to speak a new language like the natives, we know from thousands of examples that we can go on learning languages beyond the age of eighty. There are so many activities adding up to the simple word "learning" that although some of the processes become less efficient with ageing of the brain, our actual experience of learning helps us in learning new materials. Normal social and emotional development probably also needs the correct stimulating at the right time. We can observe evidence of this in those rare cases of children who have been completely neglected from birth. Sometimes illegitimate children in the country are put away in barns to conceal their existence from the neighbors. They are taught nothing, not even to be house-trained or to speak. These children then grow up mentally defective. Even if they are found and rescued by the age of four or five, it is too late. Though they can be taught a lot, their speech is always inadequate and their brains never reach the standards of their brothers or sisters.1. What can we learn from the first paragraph about the critical period? ______

单选题. A wise man once said that the only thing necessary for the triumph of evil is for good men to do nothing. So, as a police officer I have some urgent things to say to good people. Days after days my men and I struggle to hold back a tidal wave of crime. Something has gone terribly wrong with our proud American way of life. It has happened in the area of values. A key ingredient is disappearing, and I think I know what it is: accountability. Accountability isn't hard to define. It means that every person is responsible for his or her actions and liable for their consequences. Of the many values that hold civilization together—honesty, kindness, and so on—accountability may be the most important of all. Without it, there can be no respect, no trust, no law—and, ultimately, no society. My job as a police officer is to impose accountability on people who refuse, or have never learned, to impose it on themselves. But as every policeman knows, external controls on people's behavior are far less effective than internal restraint such as guilt, shame and embarrassment. Fortunately, there are still communities—small towns, usually—schools maintain discipline and where parents hold up standards that proclaim: "In this family certain things are not tolerated—they simply are not done!" Yet more and more, especially in our large cities and suburbs, these inner restraints are loosening. Your typical robber has gone. He considers your property his property; he takes what he wants including your life if you enrage him. The main cause for this break-down is a radical shift in attitudes. Thirty years ago if a crime was committed, society was considered the victim. Now in a shocking reversal, it is the criminal who is considered victimize: by his underprivileged upbringing, by the school that didn't teach him to read, by the church that failed to reach him with moral guidance, by the parents who didn't provide a stable home. I don't believe it. Many others in equally disadvantaged circumstances choose not to engage in criminal activities. If we free the criminal, even partly, from accountability, we become a society of endless excuses where no one accepts responsibility for anything. We in America desperately need more people who believe that the person who commits a crime is the one responsible for it.1. What the wise man said suggests that ______.
