听力原文： The human brain processes male and female voices differently, according to a recent study, which explains why most of us hear female voices more clearly. The study also explains how we form. mental images of people based only on the sound of their voices. The findings, published in the journal NeuroImage, might also give insight into why many men tire of hearing women speak. It seems the complexity of female voices requires a lot of brain activity.
"It is females' increased use of prosody, or the natural melody of speech, that makes their voices more complex," says author Professor Michael Hunter. Hunter, professor of medicine and biomedical sciences at the University of Sheffield's Cognition and Neuroimaging Laboratory, says these qualities are not related to pitch, but rather to the vibration and number of sound waves.
For the study Hunter and his colleagues played recordings of male and female voices to 12 men while they underwent MRI, or magnetic resonance imaging, brain scans. Test subjects assigned a gender to the voices they heard while the scans took place, and were 98 to 99 percent accurate. Researchers monitored the areas of the brain that showed activity during the scans.
The scientists found that female voices activate the brain's auditory section. But male voices activated the area at the back of the brain called the mind's eye, where people compare other individuals and things to themselves. While the researchers only analyzed how a male brain works, they theorized that female voices are always processed in the brain's auditory region, even when women are listening to other women.
But Hunter thinks female voices may also activate the mind's eye in females, since a woman would compare her voice to that of the other female speaker. Since humans process female voices in an area of the brain that's geared for sound, we tend to hear female voices more clearly. While Hunter believes female voices are complex, he says that once they are interpreted in the auditory part of the brain, they are more fully and readily decoded.

Which of the following is true according to the passage？
How many years has his own marriage lasted？
The best title for the passage would be
听力原文： Clark Warren has been a marriage counselor for 35 years -- long enough to help couples confront just about every domestic difficulty imaginable. On the personal side, he's helped six close friends as they went through three divorces each. His own marriage, happily, has lasted 43 years -- and he and his wife, Marylyn, have raised three daughters who also enjoy happiness of marriage.
So this is enough to say that Dr. Warren knows a fair bit about marriage -- from his practice, his friends, his own experience, and from his parents, who still liked to hold hands after 70 years together. And he thinks he knows what it is that makes or breaks a marriage.
The key, he says, is not necessarily family background, or chemistry, or even how old people are when they marry. It is... are you ready？ That is choosing wisely in the first place. "This choice has more to do with the eventual success of your marriage than everything else combined that you do after you get married," says this voice of experience. "If you choose someone who is highly compatible, it feels almost effortless; if you are mismatched, it's all hard work and good intentions."
