For better or worse, multiple marriages aren't just for actress Elizabeth Taylor （famous for her eight marriages） anymore． More Americans than ever are tying the knot for the third time or more． Lynn Y. Naugle, a 53-yeap-old family therapist in New Orleans, says that people's personal needs and desires simply change as their life evolves． 'What functions well in the first part of our lives may not function well in the second or third part of our lives,' she explains．The first marriage lasted 21 years, her second marriage five years．Two years ago, she wed for a third time, and she describes this union as an 'extremely easy marriage'． Today, at an estimated one of seven weddings, the bride, the groom or both are making that trip down the aisle for at least the third time．That's twice as many as a generation ago, according to the US National Centre for Health Statistics． In part, the sudden change in multiple marriages is a side effect of the 1970s divorce increase that has supplied an ever expanding pool of divorced singles．Even the simple fact that people are living longer has opened the door to marrying more often．No fault divorce laws （meaning no one is blamed for the failure of the marriage）, and cultural changes have also meant there's less pressure than in past generations to stay in a joyless or abusive marriage． While a single divorce didn't block either Ronald Reagan or Bob Dole from seeking the most highly demanding job in America—the US presidency—modern society still raises an; eyebrow at more than one marriage mistake． Indeed, there are signs that attitudes are changing．'It's coming out of the closet or becoming more accepted,' says Glenda Riley, who wrote a book on the history of divorce in the US．'There's still embarrassment on the personal level, while there is growing acceptance on the public level for three or more marriages in a lifetime．' There is no guarantee, of course, that the third time is the best．To the contrary, second and third marriages run an equal or greater risk of divorce than first marriages, which today are given 4 out of 10 odds of failing, and they tend to end more quickly．Divorce statistics show that failed second marriages typically end two years sooner than first marriages, lasting six years on average rather than eight．That leaves some doubly divorced people open for a third try at a relatively young age． 小题1:What does the underlined phrase 'tying the knot' （Para．2） mean?
