　　The Marriage Rate in U. S.

The United States has historically had higher rates of marriage than those of other industrialized countries. The current annual marriage51in the United States-about 9 new marriages for every 1,000 people-is 52 higher than it is in other industrialized countries. However, marriage is53as widespread as it was several decades ago.54of American adults who are married55from 72 percent in 1970 to 60 percent in 2002. This does not mean that large numbers of people will remain unmarried56their lives. Throughout the 20th century, about 90 percent of Americans married at some 57in their lives. Experts58that about the same proportion of today's young adults will eventually marry.

The timing of marriage has varied59over the past century. In 1995 the average age of women in the United States at the time of their first marriage was 25. The average age of men was about 27. Men and women in the United States marry for the first time at an average of five years later than people did in the 1950s.60, young adults of the 1950s married younger than did any previous61in U. S. history. Today's later age of marriage is62the age of marriage between 1890 and 1940. Moreover, a greater proportion of the population was married (95 percent) during the 1950s than at any time before63. Experts do not agree on why the "marriage rush" of the late 1940s and 1950s occurred, but most social scientists believe it represented a64to the return of peaceful life and prosperity after 15 years of severe economic 65and war.

　　So Many 'Earths'

The Milky Way ( 銀河) contains billions of Earth-sized planets that could support life that's the finding of a new study. It draws on date that came from NASA's top planet-hunting telescope.

A mechanical failure recently put that Kepler space telescope out of service. Kepler had played a big role in creating a census of planets orbiting some 170, 000 stars. Its data have been helping astronomers predict how common planets are in our galaxy. The telescope focused on hunting planets that might have conditions similar to those on Earth.

The authors of a study, published in The Proceedings of the National Academy of sciences, conclude that between 14 and 30 out of every 100 stars, with a mass and temperature similar to the Sun, may host a planet that could support life as we know it. Such a planet would have a diameter at least as large as Earth's, but no more than twice that big. The planet also would have to orbit in a star's habitable zone. That's where the surface temperature would allow any water to exist as a liquid.

The new estimate of how many planets might fit these conditions comes from studying more than 42, 000 stars and identifying suitable worlds orbiting them. The scientists used those numbers to extrapolate ( 推算 ) to the rest of the stars that the telescope could not see.

The estimate is rough, the authors admit. If applied to the solar system, it would define as habitable a zone starting as close to the Sun as Venus and running to as far away as Mars. Neither planet is Earthlike (although either might have been in the distant past). Using tighter limits, the researchers estimate that between 4 and 8 out of every 100 sunlike stars could host an Earth-sized world. These are ones that would take 200 to 400 days to complete a yearly orbit.

Four out of every 100 sunlike stars doesn't sound like a big number. It would mean, however, that the Milky Way could host more than a billion Earth-sized planets with a change for life.

The Kepler space telescope has been in service for 15 years.
