The problem is that in the last generation or so we yet come to assume that women should be able, and should want, to do everything that by tradition men have done at the same time as pretty well everything that by tradition women have done. And it's just not possible. Indeed since adopting a male agenda in life is arguably only another form. of submission, quite a number of highly educated and economically privileged women are now opting to take career breaks so as to be at home with their children for longer than that insulting 18 weeks.

The most welcome trend in parenting is that men are participating more and more. Even that is not free of conflict, though. Intellectually, women want men to be equal parents and do their share. But there's often a contradictory emo- tional sub-text because children are the last bastion of distaff power in the family. "I want him to help me but this is my territory and being better at it is one of the few things I've got as a female. "In truth, although they haven't had genera- tions of practice, there's no reason why men can't rear children as well as women. Men left to cope after bereavement or divorce, as well as some who take on the role of principal cater within a partnership, are already doing it.

A study that will cost $ 3. 2 billion and last more than two decades to track the health of 100,000 U. S.children from before birth to age 21 will be Iaunched in January, U. S. health officials said on Friday.

Officials from the U. S. government's National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that af- fect later development, with the goal of learning new ways to treat or prevent illness.

The study will examine hereditary and environmental factors such as exposure to certain chemicals that affect health.

Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to con- struct their residences, the NIH said.

Officials said more than $ 200 million has been spent already and the study is projected to cost $ 3. 2 billion.

"We anticipate that in the long term, what we lea:m from the study will result in a significant savings in the nation's health care costs, " Dr. Duane Alexander,r who heads the NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters.

The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up pregnant women whose babies will then be followed to age 21.

Some of the early findings will be about factors behind pre-term birth, which has become more common

in recent years, according to Dr. Peter Scheidt of the NIH, who heads the study.

The people taking part will be from rural, urban and suburban areas, from all income and educa-

tional levels and from all racial groups, the NIH said.

The aim of the study is to find new ways to____.

A.conduct research

B.track public health

C.prevent or treat illness

D.s.peed up development

听力原文：W: Professor Wilson, can you spare me a few minutes？

M: That's OK. Actually, I'm on my way to an appointment with students, so please make this quick.

W: My name is Maria Taylor, and I'm in your Psychology class at 2:00.

M: Oh, yes. I recall now. You always ask good questions about the lectures. What can I do for you now？

W: You say in your lecture last week that IQ changes little from childhood, but the skills of emotional intelligence can be learned at any age.

M: Right, it's not easy, however. You know, growing your emotional intelligence takes practice and commitment and improving your emotional intelligence takes time, say, several months.

W: Why do you say improving an emotional intelligence takes months rather than days？

M: Well, you know, the emotional centers of the brain are involved.

W: The emotional centers of the brain？

M: Yes. The thinking brain learns technical skills and purely cognitive abilities. It gains knowledge very quickly, but the emotional brain does not.

W: Why？

M: Because to master a new behavior, the emotional centers need repetition and practice.

W: So it takes time.

M: Yes. Improving your emotional intelligence, then, is similar to changing your habits. You have to change your old habits and replace them with the new ones.

W: Oh, I see. And another question I want to ask you is. can we say emo tional intelligence is the opposite of IQ？

M: No. You know some people are blessed with a lot of both while some with little of either. What we are doing now is trying to find out how they complement each other.
