2. Anyone meeting Matthew Daniels for the first time could easily assume that he is the product of a conventional, even privileged childhood. With his well-spoken manner, his Ivy League education, and his business card reading "President, Massachusetts Family Institute," Mr. Daniels is the picture of youthful American success. But Daniels can tell a story that refutes those assumptions about his childhood. His father abandoned the family when he was 2. His mother took a job as a secretary. But on her way home one evening she was mugged, sustaining injuries that eventually left her unable to work, the family went on welfare. Growing up in New York's Spanish Harliem, Daniels was one of only four white students until ninth grade. Despite a difficult environment, he stayed out of trouble. He even won a full scholarship to Dartmouth College, graduating in 1985. How did he do it? He credits his mother's religious faith. "It's why I didn't end up like the guys in my neighborhood," he says. "Some went to prison." Although his father, a writer, didn't support the family, he maintained contact with his son, emphasizing the importance of books and education. Because of his experience, Daniels has become a passionate advocate of the two-parent family. He sees it as an institution under cultural siege, generally supported by "the person in the street" but too often dismissed by those in academic and media circles. Some of the groups, he says, have miscalculated the social consequences of "trying to convince people that there are all sorts of" alternative family forms. Even during law school, he encountered professors who were "openly hostile to the idea that we need two-parent families to have a healthy society." Reporters and academics may not be the only ones ambivalent about marriage. A new study of college textbooks finds that many texts on marriage paint a pessimistic view. They emphasize divorce and domestic violence, the report says, and focus far more on adult relationships and problems than on children's needs. Question:According to the passage, Daniels is a __________ man.

7. From the moment that an animal is born it has to make decisions. It has to decide which of the things around it are for eating, and which are to be avoided; when to attack and when to run away. The animal is, in effect, playing a complicated and potentially very dangerous game with its environment, discomfort or destruction. This is a difficult and unpleasant business and few animals would survive if they had to start from the beginning and learn about the world wholly by trial and error, for there are too many possible decisions which would prove fatal. So we find, in practice, that the game is always arranged in favor of the young animal in one way or another. Either the animal is protected during the early stages of its learning about the world around it, or the knowledge of which way to respond is built into its nervous system from the start. The fact that animals behave sensibly can be attributed partly to what we might call genetic learning, to distinguish it from individual learning that an animal does in the cause of its own life time. Genetic learning is learning by a species as a whole, and it is achieved by selection of those members of each generation that happen to behave in the right way. However, genetic learning depends upon a prediction that the future will more or less exactly resemble the past. The more variable individual experience is likely to be, the less efficient is genetic learning as a means of getting over the problems of the survival game. It is not surprising to find that very few species indeed depend wholly upon genetic learning. In the great majority of animals, behavior is a compound of individual experience and genetic learning to behave in particular ways. Question:"Genetic learning" refers to ________.
专业答案:----
正确选项:----
A. learning after an animal is born
B. learning obtained by some members of each generation who happen to behave properly
正确答案:----

C. learning gained by all the members in a species
