The world is not coming to an end on December 21, 2012, the US space agency insisted on Monday in a rare campaign to dispel widespread rumors fueled by the Internet and a new Hollywood movie.

The latest big screen offering from Sony Picture, 2012, arrives in theaters on Friday, with a 200-million-dollar production about the end of the world supposedly based on myths (虚构的故事) backed by the Mayan calendar. It is claimed that the end of time will come as a Planet X—or Nibiru—heads toward or collides with the Earth.

Some websites accuse NASA of hiding the truth on the planet’ s existence, but the US space agency denounced such stories as an “Internet hoax(恶作剧) ”. “There is no factual basis for these claims,” NASA said in a question-and-answer posting on its website. “If such a collision were real, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye. Obviously, it does not exist. Credible scientists worldwide know of no threat associated with 2012,” it insisted. “After all, our planet has been getting along just well for more than four billion years.” added NASA.

There is another planet, Eris, floating in space. But the small planet similar to Pluto will remain safely fixed in the outer solar system and it can come no closer than four billion miles to the Earth, according to NASA.

Initial theories set the disaster for May 2003, but when nothing happened the date was moved forward to the winter in 2012 to coincide with the end of a cycle of the ancient Mayan calendar.

NASA insisted the Mayan calendar in fact does not end on December 21, 2012, as another period begins immediately afterward. And even if the planets were to line up as some have forecast, the effect on our planet would be “negligible”, NASA said.

“And while comets and asteroids (小行星) have always hit the Earth, big hits are very rare, ” NASA noted. The last major impact was believed to be 65 million years ago, resulting in the end of dinosaurs.

“We have already determined that there are no threatening asteroids as large as the one that killed the dinosaurs,” the space agency said.

More surprising, perhaps, than the current difficulties of traditional marriage is the fact that marriage itself is alive and thriving（旺盛的）. As Skolnich notes, Americans are a marrying people: relative to Europeans, more of us marry and we marry at a younger age. Moreover, after a decline（衰退）in the early 1970s, the rate of marriage in the United States is now increasing. Even the divorce（离婚）rate needs to be taken in this pro- marriage context: some 80 percent of divorced individuals remarry. Thus, marriage remains by far the preferred way of life for the vast majority of the people in our society.

　　What has changed more than marriage is the nuclear family. Twenty- five years ago, the typical American family consisted of the husband, the wife, and two or three children. Now, there are many marriages in which couples have decided not to have any children, and there are many marriages where at least some of the children are from the wife’s previous marriage, or the husband’s, or both. Sometimes these children spend all of their time with one parent from the former marriage; sometimes they are shared between the two former spouses （配偶）．

　　Thus, one can find every type of tamely arrangement. There are marriages without children; marriages with children from only the present marriages; marriages with “full - time” children from both the present and former marriages; marriages with“full- time”children from the present marriage and“ part- time”children from former marriages. There are stepfathers, stepmothers, half- brothers and half - sisters. It is not all that unusual for a child to have four parents and eight grandparents! These are enormous changes from the traditional nuclear family. But even so, even in the midst of all this, there remains one constant: most Americans spend most of their adult lives married.

By calling Americans a marrying people the writer means that ________.

　　A. Americans are more traditional than Europeans

　　B. Americans expect more out of marriage than Europeans

　　C. there are more married couples in the USA than in Europe

　　D. more of Americans, as compared with Europeans, prefer marriage and they accept it at a younger age

Divorced Americans ________ .

　　A. prefer the way they live

　　B. will most likely remarry

　　C. have lost interest in marriage

　　D. are the majority of people in the society

Which of the following can be presented as the picture of today’s American families？

　　A. Which types of family arrangements have become socially acceptable.

　　B. A typical American family consists of only a husband and a wife.

　　C. Americans prefer to have more kids than before.

　　D. There are no nuclear families any more.
