For the past several decades, it seems there's bee...

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.

I have learned something about myself since I moved from Long Island to Florida three
years ago. Even though I own a home in Port St. Lucie just minutes from the ocean, an uncontrollable urge wells up to return to Long Island even as others make their way south. I guess I am a snowbird stuck in reverse. Instead of enjoying Florida’s mild winters, I willingly endure the severe weather on Long Island, the place I called home for 65 years.

I’m like a migratory bird that has lost its sense of timing and direction, my wings flapping against season.

So what makes me fly against the tide of snowbirds? The answer has a lot to do with my reluctance to give up the things that define who I am. Once I hear that the temperature on Long Island has dipped into the range of 40 to 50 degrees, I begin to long for the sight and crackling sound of a wood fire. I also long for the bright display o£ colors — first in the fall trees, and then in the limits around homes and at Rockefeller Center. Floridians decorate too, but can’t create the special feel of a New England winter.

I suppose the biggest reason why I return is to celebrate the holidays with people I haven’t seen in months. What could be better than sitting with family and friends for a Thanksgiving turkey dinner, or watching neighbors’ children excitedly open gifts on Christmas? Even the first snowfall seems special. I especially enjoy seeing a bright red bird settling on a snow-covered branch (My wife and I spend winters at a retirement community in Ridge, and I’m grateful that I don’t have to shovel.)

While these simple pleasures are not unique to Long Island, they are some of the reasons why I come back. Who says you can’t go home?

(1) 单选题What does the underlined word "snowbird" in Paragraph 1 refer to?

A.A person spending winter in a warmer climate.

B.A bird seen chiefly in winter.

C.A person permanently living in a foreign country.

D.A bird flying to the south in winter.

(2) 单选题What’s the difference between Florida and Long Island?

A.Winters in Long Island are milder.

B.The snowbirds in Long Island are rarer.

C.Weather in Long Island is severer.

D.Long Island is nearer to the ocean.

(3) 单选题What did the author miss most when he was in Florida?

A.The colorful light display.

B.The family gathering.

C.The cold temperature.

D.The winter landscape.

(4) 单选题What’s the author’s purpose in writing the text?

A.To praise the beauty and warmth of his hometown.

B.To describe his dream to be a free bird.

C.To explain the reasons for moving from his hometown.

D.To express his feeling of missing his hometown.
