【文章內(nèi)容簡介】 ation between finger ration and numeracy, but those with higher ratios—probably indicating low hormone levels—had better scores on verbal abilities. These sex173。specific correlations show how tricky it is to define the roles of sex hormones, says psychologist S． Marc Breedlove of Michigan State University in East Lansing. The range of normal levels of the hormone is different in males and females, so parable levels would have very different meanings depending on the sex of the individual. And the timing of hormone surges is as important as levels. Nevertheless, Brosnan believes finger measurements might be useful for predicting cognitive abilities—although he acknowledges that “ we are not suggesting that finger length measurements could replace SAT tests”. Others are more cautious, pointing out that scientists still have not confirmed that finger ratio is a reliable marker for prenatal hormone levels. 28 .What can we learn from the first paragraph? never show interest in people39。s fingers. women have different kinds of fingers. males, the ring finger may equal the index in length. females, the ring finger may equal the index in length. 29 .What is the author39。s attitude to Brosnan39。s research? . . . . 30.

D Integrity Integrity is the quality of being honest and strong about what you believe to be right. The concept of integrity has played a key role in moral philosophy throughout history and is promoted in all societies because of its importance to social relations. Individual integrity is vital to society, one that enables people to make use of their capacity for critical reflection, does not force people to take up particular roles and does not encourage individuals to betray each other. Besides, societies can be favorable to the development of individual integrity. Individual integrity can lift up the spirits of the entire society. It can shape the lives of people living in a particular society, the lives of all fellow people and, in its broadest sense, even the destiny(命運 ) of a nation. By contrast, if those living in the society are corrupt, it could have bad effects, jeopardizing the healthy morality of the society. On the other hand, a society can be favorable to the development of individual integrity. Society expects and requires integrity. A society consisting of people of integrity, and people who never promise on their principles, could have a positive mark on the personal development of its members. Being a part of such a morally lively munity could serve as a basis for absorbing traits of good character. This could be of a distinct advantage to any individuals in the society. However, some social structures are of the wrong sort for some individuals to pursue(追求 ) integrity. If that is the case, we have to ask questions about the moral nature of society first before raising questions about individual integrity. Questions about integrity may turn out to be about what kind of society it is, rather than about the relationship between individual interests and characteristics of a society. The pursuit of adequate individual integrity often depends, not so much on understanding who one is and what one believes and is mitted to, but rather understanding what one?s society is and imagining what it could be. Under no circumstances can we underestimate the importance of human integrity in a society. People, who are honest, trustworthy, passionate and caring, are the factors decisive in the growth of individuals as well as the development of a society. 32.
