Taking paternity leave (陪产假) shortly after the birth of a new son or daughter may be the key to developing strong father-child bonds that last for years, says new research from Ball State University.

“We find that 9-year-olds report greater satisfaction with father involvement,” said Richard Petts, a Ball State sociology professor who carried out the research with Chris Knoester at the Ohio State University and Jane Waldfogel at Columbia University. “They feel closer to their fathers and report better communication with their dads if their fathers take paternity leave, and especially if their fathers take two or more weeks of leave.”

“We found evidence that part of the reason why two or more weeks of paternity leave may lead to 9-year-olds expressing greater satisfaction seems to be that longer periods of paternity leave-taking link to parental relationship satisfaction,” said Petts.

The study is the latest in a series examining the effects of parental leave in the development of children and its influence on the family. It is also the first research known to assess the associations between paternity leave and children’s opinions of father-child relationship quality in the United States, Petts said.

Petts said the findings of the study will help families and policymakers (政策制定者) who aim to strengthen families and improve higher quality father-child relationships.

The present structure (结构) of paternity leave in the United States provides limited opportunities for fathers to take leave and, in fact, often discourages fathers from taking leave, he said.

“The possibility to take leave is often limited to higher-income families,” Petts said. “A lack of a national paid family leave policy limits access to important benefits for American families. The present structure may be increasing inequalities.” Petts said that providing equal access to paternity leave may help to change these patterns and strengthen family relationships.

1.How was the research probably carried out?

A.By tracking families. B.By talking with mothers.

C.By interviewing the kids. D.By recording children’s behavior.

2.What is found about paternity leave?

A.It makes young kids become dependent.

B.It is determined by parental relationships.

C.It encourages men to become better fathers.

D.It improves father-child relationship quality.

3.What do we know about the research?

A.It is welcomed by young fathers. B.It is the first to study parental leave.

C.It is probably helpful to policymakers. D.It is more important than similar studies.

4.What is the problem with the present structure of paternity leave in the US?

A.Paid paternity leave is only two weeks long.

B.There is no policy to encourage paternity leave.

C.Low-income families think little of paternity leave.

D.High-income fathers are too busy to take paternity leave.

You don’t expect your child to grow up to be a heroin addict．From the moment of her birth, you have hopes and dreams about the future，but they never include heroin addiction．That couldn’t happen to your child, because addiction is the result of a bad environment．bad parenting．There is most definitely someone or something to blame．

That’s what I used to believe．But after failed rehab and long periods of separation from my heroin-addicted daughter，after years of holding my breath，waiting for another relapse，I now believe  there is no blame．

After Katie admitted her addiction．I struggled to understand how this could have  happened to my daughter—a bright，beautiful，talented and most importantly，loved young woman．When the initial shock wore off,I analyzed and inventoried all the whys and hows of Katie’s addiction．I searched for someone or something to blame．I blamed her friends．I blamed her dad．I blamed our divorce．But mostly, I blamed myself．My desperate heart convinced me that I should have prevented Katie’s addiction．and that given another chance．I could correct my mistakes．

When Katie came home from rehab．I approached each day with the zeal of a drill sergeant. I championed the 12-step program and monitored her improvement daily as though curing heroin addiction was as simple as nursing a cold．I drove her to therapy sessions and AA meetings． I controlled everything and left nothing to chance. But in spite of my efforts，Katie didn’t get better．She left my home，lost again to the powerful grip of addiction．

In the long days，weeks and months that followed，I gathered bits and pieces of old beliefs and tried to assemble them into something whole．Sometimes I gave up．and sometimes I simply let go,Gradually, my search for blame changed to a longing for hope．I comforted myself with the only thing that still connected me to my daughter：love．

I thought about Katie every day，and I missed her．I cried．and worried about her safety and whereabouts. I wrote letters I knew she’d never see．Sometimes I woke up panicked in the middle of the night, certain that mother’s intuition(直觉)was preparing me for something bad．But through it all，I loved her.

I don’t know why or how my daughter became addicted to heroin：I do know that it doesn’t really matter．Life goes on and Katie is still my daughter．

Katie and I meet for breakfast on Friday mornings now．We drink coffee and talk．I don’t try to heal her. I just love her．Sometimes there is pain and sorrow，but there is no blame．I believe there is only love．

1.The reason why the daughter became a heroin addict was________．

A．found by her mother at last      B．not mentioned in the passage

C．her friends’invitation          D．her parents’divorce

2.The underlined sentence means ________．

C．the mother persuaded her daughter to give up heroin

D．the mother didn’t live with her daughter later
