【简答题】
President Barack Obama set out his plans for the nation on January 27. At the top of his to-do list: his jobs for Americans, health care and education. “Although we have our difficulties, our union is strong. We do not give up. We do not stop,” President Barack Obama told American in his State of the Union speech on January 27. Guests and government officials filled the hall of the House of Representatives (众议院). Obama looked back on his first year in office and explained his plan for the future. He dealt with important matters, including health care, the nation’ s high unemployment, national security (安全) and education. Many times during the 70-minute speech, people in the hall clapped (拍手) their hands happily. The U.S. law system requires the President to report regularly to government officials. Presidents see the speech as an opportunity to set their goals and encourage the nation. The President devoted much of his speech to the plight of unemployed (失业的) Americans. “Jobs must be our Number 1 focus (焦点) in 2010,” he said. “People are out of work. They are hurting.” Obama also stressed the value of education. “The best way for people to lead a better life is a first-class education.” he told the nation. Following the President’s speech, the other party always gets the chance to speak. Bob McDonnell, the new governor of Virginia, spoke for Republicans (共和党人). He agreed with many of Obama’s goals, but pointed out policy difference. He tried to persuade both parties to work together. The President had made the same point earlier in the evening. He promised to hold monthly meetings with members of both parties. “Let’s show the American people,” he said, “that we can do it together.” 小题1:It can be inferred (推断) from the passage that Obama’s speech on January 27 __________. was made to explain his plan for the future was welcomed by the government officials present was given to ask for foreign help was actually boring 小题2:The underlined word “plight” in para. 5 probably means __________.
