Passage 1
The United States has historically had higher rates of marriage than those of other industrialized countries. The current annual marriage 56 in the United States—about 9 new marriages for every 1,000 people—is 57 higher than it is in other industrialized countries. However, marriage is 58 as widespread as it was several decades ago. 59 of American adults who are married 60 from 72 percent in 1970 to 60 percent in . This does not mean that large numbers of people will remain unmarried 61 their lives. Throughout the 20th century, about 90 percent of Americans married at some 62 in their lives. Experts 63 that about the same proportion of today’s young adults will eventually marry.
The timing of marriage has varied 64 over 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 an average of five years later than people did in the 1950s. 65 , young adults of the 1950s married younger than did any previous 66 in U.S. history. Today’s later age of marriage is 67 the 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 before 68 . Experts do not agree on why the “marriage rush” of the late 1940s and 1950s occurred, but most social scientists believe it represented a 69 to the return of peaceful and prosperity after 15 years of severe economic 70 and war.

Passage 2
In recent years a new farming revolution has begun, one that involves the 61 of life at a fundamental level – the gene. The study of genetics has 62 a new industry called biotechnology. As the name suggest, it 63 biology and modem technology through such techniques as genetic engineering. Some of the new biotech companies specialize in
agriculture and are working feverishly to 64 seeds that give a high yield, that 65 diseases, drought and frost, and that reduce the need for 66 chemicals. If such goals could be achieved, it would be most 67. But some have raised concerns about genetically engineered crops.
In nature, genetic diversity is created within certain 68 .A rose can be crossed with a different kind of rose, but a rose will never cross with a potato. Genetic engineering, 69 usually involves taking genes from one species and inserting them into another 70 to transfer a desired characteristic. This could mean, for example, selecting a gene which leads to the production of a chemical with anti-freeze 71 from an artic fish, and inserting it into a potato or strawberry to make it frost-resistant. 72, then, biotechnology allows humans to 73 the genetic walls that separate species.
Like the green revolution, 74 some call the gene revolution contributes to the problem of genetic uniformity---some say even more so 75 geneticists can employ techniques such as cloning and 76 culture(培养), processes that produce perfectly 77 copies. Concerns about the erosion of biodiversity, therefore, remain. Genetically altered plants, however, raise new 78, such as the effects that they may have on us and the environment. “We are flying blindly into a new 79 of agricultural biotechnology with high hopes, few constraints, and little idea of the potential 80,” said science writer Jeremy Rifkin.
