Barack Obama made his victory speech in Chicago after a hard-fought campaign.

Democratic Senator Barack Obama has won the US presidential election, and will become the 44th President of the United States-the first African-American in the country's history to do so.

President-elect Obama marked his victory with a speech to a crowd of tens of thousands of people in his hometown of Chicago.

Obama described his election as a "defining moment' in the history of the United States, saying that "change has come to America".

The BBC's spokesman in Washington says that in electing Barack Obama, the American people have expressed their unhappiness with the present state and rejected their country's historical racial divisions.

The Australian Prime Minister summed up how many people felt when he congratulated President-elect Obama.

“Forty-five years ago Martin Luther King had a dream of an America where men and women would be judged not on the colour of their skin but on the content of their character. Today what America has done is turn that dream into a reality," said Prime Minister Kevin Rudd.

President-elect Obama will not take office until 20th January next year. However, when he does become president, he will face many serious challenges, including two foreign wars, climate change and what he has described as " the worst financial crisis (经济危机)in a century."

But the mood of the country is optimistic, according to most commentators, and Obama himself appears to enjoy the challenge.

"The road ahead will be long. Our climb will be difficult. We may not get there in one year or even in one term, but America--I have never been more hopeful than I am tonight that we will get there," said the next President of the United States.

41. Which of the following is TRUE according to the passage?

A. It was not a difficult process for Obama to win the US presidential election.

B. The American people welcome the historical racial divisions.

C. What Martin Luther King dreamed about America has come true.

D. After the election Obama didn't say anything about his victory.

42. According to the passage, it seems that in the United States, _____________.

A. people may still be treated unequally because of their color of skin.

B. people are experiencing two civil wars.

C. Americans are enjoying the economy developing.

D. People are not satisfied with President-elect.

43. From the last two paragraphs, we can learn that________________.

A. the attitude of American people to their country's future is not clear.

B. Obama has confidence in American future and ready to face it.

C. the road to America will be long.

D. the change of America is not hard to achieve.

44. What is probably the best title to the passage?

A. Historical presidential election                          B. The first African-American President

C. Change has come                                             D. Comments about America

Nearly two thousand years have passed since a census decreed by Caesar Augustus become part of the greatest story ever told. Many things have changed in the intervening years. The hotel industry worries more about overbuilding than overcrowding, and if they had to meet an unexpected influx, few inns would have a manager to accommodate the weary guests. Now it is the census taker that does the traveling in the fond hope that a highly mobile population will stay long enough to get a good sampling. Methods of gathering, recording, and evaluating information have presumably been improved a great deal. And where then it was the modest purpose of Rome to obtain a simple head count as an adequate basis for levying taxes, now batteries of complicated statistical series furnished by governmental agencies and private organizations are eagerly scanned and interpreted by sages and seers to get a clue to future events. The Bible does not tell us how the Roman census takers made out, and as regards our more immediate concern, the reliability of present day economic forecasting, there are considerable differences of opinion. They were aired at the celebration of the 125th anniversary of the American Statistical Association. There was the thought that business forecasting might well be on its way from an art to a science, and some speakers talked about newfangled computers and high-falutin mathematical system in terms of excitement and endearment which we, at least in our younger years when these things mattered, would have associated more readily with the description of a fair maiden. But others pointed to the deplorable record of highly esteemed forecasts and forecasters with a batting average below that of the Mets, and the President-elect of the Association cautioned that “high powered statistical methods are usually in order where the facts are crude and inadequate, the exact contrary of what crude and inadequate statisticians assume.” We left his birthday party somewhere between hope and despair and with the conviction, not really newly acquired, that proper statistical methods applied to ascertainable facts have their merits in economic forecasting as long as neither forecaster nor public is deluded into mistaking the delineation of probabilities and trends for a prediction of certainties of mathematical exactitude.

Taxation in Roman days apparently was based on

[A]. wealth. [B]. mobility. [C]. population. [D]. census takers.

The American Statistical Association

[A]. is converting statistical study from an art to a science.

[B]. has an excellent record in business forecasting.

[C]. is neither hopeful nor pessimistic.

[D]. speaks with mathematical exactitude.

The message the author wishes the reader to get is

[A]. statisticians have not advanced since the days of the Roman.

[B]. statistics is not as yet a science.

[C]. statisticians love their machine.

[D].computer is hopeful.

The “greatest story ever told” referred to in the passage is the story of

[A]. Christmas. [B]. The Mets.

[C]. Moses. [D]. Roman Census Takers.

What I Want for You and Every Child in America

                by President-Elect Barack Obama

Dear Malia and Sasha,

I know that you’ve both had a lot of  1 these last two years during the campaign, going to picnics and parades and state fairs, eating all sorts of junk food your mother and I probably shouldn’t have let you have. But I also know that it hasn’t always been easy for you and Mom, and that although you are both excited about that new puppy(幼犬), it doesn’t 2 for all the time we’ve been apart. I know 3 I’ve missed these past two years, and today I want to tell you a little more about why I decided to take our family on this journey.

When I was a young man, I thought life was all about me--about how I’d 4 my way in the world, become successful, and get the things I want. But then the two of you came into my 5  with all your curiosity and mischief (捣乱) and those smiles that never 6 to fill my heart and light up my day. I soon found that the greatest joy in my life was the joy I saw in yours. That’s why I ran for President: because of what I want for you and for every child in this nation.

I want all our children to go to schools 7 of their potential---schools that challenge them, inspire them, and instill (灌输) in them a sense of 8 about the world around them. I want them to have the chance to go to college 9 their parents aren’t rich. And I want them to get good jobs: jobs that pay well and give them benefits like health care, jobs that let them have time to spend time with their own 10 .

I want us to 11 back the boundaries(界限) of discovery so that you’ll live to see new technologies and inventions that improve our lives and make our planet cleaner and safer. And I want us to push our own human boundaries to reach 12 the divides(分水岭) of race and region, gender and religion that 13 us from seeing the best in each other.

That was the 14 your grandmother tried to teach me when I was your age, reading me the opening lines of the Declaration of Independence and telling me about the men and women who marched for 15 because they believed those words put to paper two centuries ago should mean 16 .

She helped me understand that America is great not because it is perfect but because it can always be made better and that the 17 work of perfecting our union falls to each of us. It’s a duty we pass on to our children.

These are the things I want for you--- to 18 in a world with no limits on your dreams and no achievements beyond your reach. And I want every child to have the same 19 to learn and dream and grow that you girls have. That’s why I’ve taken our family on this great adventure.

I am so proud of both of you. I love you 20 you can ever know. And I am grateful every day for your patience, confidence, grace, and humor as we prepare to start our new life together in the White House.
