According to the majority of Americans, women are every bit as capable of being good political leaders as men. The same can be said of their ability to dominate the corporate boardroom. And according to a new Pew Research Center survey on women and leadership, most Americans find women indistinguishable from men on key leadership traits such as intelligence and capacity for innovation, with many saying they’re stronger than men in terms of being passionate and organized leaders. So why, then, are women in short supply at the top of government and business in the United States？ According to the public, at least, it’s not that they lack toughness, management talent or proper skill sets. It’s also not all about work-life balance.Although economic research and previous survey findings have shown that career interruptions related to motherhood may make it harder for women to advance in their careers and compete for top executive jobs, relatively few adults in the recent survey point to this as a key barrier for women seeking leadership roles. Only about one-in-five say women’s family responsibilities are a major reason why there aren’t more females in top leadership positions in business and politics. Instead, topping the list of reasons, about four-in-ten Americans point to a double standard for women seeking to climb to the highest levels of either politics or business, where they have to do more than their male counterparts to prove themselves. Similar shares say the electorate (选民) and corporate America are just not ready to put more women in top leadership positions. As a result, the public is divided about whether the imbalance in corporate America will change in the foreseeable future, even though women have made major advances in the workplace. While 53% believe men will continue to hold more top executive positions in business in the future, 44% say it’s only a matter of time before as many women are in top executive positions as men. Americans are less doubtful when it comes to politics: 73% expect to see a female president in their lifetime. （2019.6月四级真题） Q: What do we learn from previous survey findings about women seeking leadership roles？
A、They have unconquerable difficulties on their way to success.
B、They are lacking in confidence when competing with men.
C、Their failures may have something to do with family duties.
D、Relatively few are hindered in their career advancement.
Almost every society has certain traditional ideas about marriage. For example，most societies expect men and women to marry. Most cultures also have traditions about the role and duties of a husband and a wife. Traditionally，the husband is expected to earn a living，and the wife is expected to keep house and raise children.
Many Americans did not follow traditional marriage patterns. For example，a large number of married couples share responsibilities that have been traditionally handled by either the husband or the wife. An increasing number of married women have paying jobs and help support their families financially. In 1940s，about 15 percent of all married women earned money. In the early 1990s，about 60 percent held a full-or part-time job. More and more husbands share responsibilities traditionally handled by women，such as cooking，doing housework，and caring for children.
On the average，men and women stay single longer than they once did. In 1950s，men married at an average age of 23，and women married at an average age of 20. By the mid-1990s，the average marriage age was about 26.5 for men and about 24.5 for women.
An increasing number of people choose not to marry. If a man and a woman wish to avoid marriage，they may decide to live together with no formal obligations to each other. This arrangement is more common among young adults，but some couples of all ages live together without marrying. (239 words)

For the past several decades, it seems there's been a general consensus on how to get ahead in America: Get a college education, find a reliable job, and buy your own home. But do Americans still believe in that path, and if they do, is it attainable？ The most recent National Journal poll asked respondents about the American dream, what it takes to achieve their goals, and whether or not they felt a significant amount of control over their ability to be successful. Overwhelmingly, the results show that today， the idea of the American dream—and what it takes to achieve it—looks quite different than it did in the late 20th century. By and large, people felt that their actions and hard work—not outside forces—were the deciding factor in how their lives turned out. But respondents had decidedly mixed feelings about what actions make for a better life in the current economy. In the last seven years, Americans have grown more pessimistic about the power of education to lead to success. Even though they see going to college as a fairly achievable goal, a majority—52 percent—think that young people do not need a four-year college education in order to be successful. Miguel Maeda, 42, who has a master's degree and works in public health, was the first in his family to go to college, which has allowed him to achieve a sense of financial stability his parents and grandparents never did. While some, like Maeda, emphasized the value of the degree rather than the education itself, others still see college as a way to gain new perspectives and life experiences. Sixty-year-old Will Fendley, who had a successful career in the military and never earned a college degree, thinks "personal drive" is far more important than just going to college. To Fendley， a sense of drive and purpose, as well as an effective high-school education, and basic life skills, like balancing a checkbook, are the necessary ingredients for a successful life in America. 51.It used to be commonly acknowledged that to succeed in America, one had to have _____.
A.an advanced academic degree
B.an ambition to get ahead
C.a firm belief in their dream
D.a sense of drive and purpose
52.What is the finding of the latest National Journal poll concerning the American dream_____
A.More and more Americans are finding it hard to realize.
B.It remains alive among the majority of American people.
C.Americans' idea of it has changed over the past few decades.
D.An increasing number of young Americans are abandoning it.
53.What do Americans now think of the role of college education in achieving success_____
A.It still remains open to debate.
B.It has proved to be beyond doubt.
C.It is no longer as important as it used to be.
D.It is much better understood now than ever.
54.How do some people view college education these days_____
A.It promotes gender equality.
B.It needs to be strengthened.
C.It adds to cultural diversity.
D.It helps broaden their minds.
55.What is one factor essential to success in America, according to Will Fendley_____
A.A desire to learn and to adapt.
B.A strong sense of responsibility.
C.A willingness to commit oneself.
D.A clear aim and high motivation.
But I wonder:If American education is so poor,why is it that this is still the country of innovation. When I was 12 in Indonesia,I had to memorize the names of all the world's major cities,from Kabul to Karachi.At the same age,my son,who was brought up a Californian,thought that Buenos Aires was Spanish for good food.However,unlike children of his age in Asia and Europe,my son had studied creative geography.When he was only 6,he drew a map of the route that he traveled to get to school,including the streets,the traffic signs and the houses that he passed.
Dissatisfied American parents forget that in this country their children are able to experiment freely with ideas; without this they will not really be able to think or to believe in themselves.
Critics of American education cannot grasp one thing:freedom.America,I think,is the only country that extends even to children the license to freely speak,write and be creative.Our public education certainly is not perfect, but it is a great deal better than any other.I think I have found the answer to my question.
