     Benjamin Banneker was born a few months before another great American-George Washington.

Benjamin was black, but he was not a slave.He and his mother and his grandmother were free.

     Benjamin's grandmother came from England.In America she got a job and worked for many years

to pay for her boat trip across the ocean.After working many more years, she saved enough money to

buy a farm.Benjamin lived with her for a while.She taught him to read and write and do arithmetic.

     Benjamin's neighbors knew that he was clever.They were not surprised when he built a large wooden

clock.He made each piece after studying a small pocket watch.The clock made him famous, for it was

one of the first clocks built in America.People from other places began to send hard problems of all kinds

for Benjamin to settle.

     Thomas Jefferson learned of Benjamin Banneker's ability to settle hard problems.He asked Banneker

to help build the city that was to be the capital of the United States-Washington, D. C.

  Banneker worked hard on the plans for the city.He marked where the  streets and buildings-the Capital (国会大厦), the White House, and many others?should be built.

     Later, L'Enfant, the Frenchman who had designed the new city, had a  quarrel, and went back to

France in anger.He took all of the plans with him.The workmen couldn't build without any plans to follow.

      For a while it seemed that the plans for the capital might have to be  changed.But Benjamin Banneker

remembered the plans he had helped draw.He drew each again just as he once had built each piece of his clock.

      If it weren't for Benjamin Banneker, Washington, D. C.might look very different from the way it does

today.

 上述固定资产和无形资产计提的折旧和摊销额均计入当期管理费用，存货于2007年对外出售60％，2008年对外出售剩余的40％. (4)2007年度乙公司实现净利润1200万元，其中，1～6月实现净利润600万元。 (5)2008年3月10日，乙公司股东大会通过决议，宣告分派2007年度现金股利1000万元。 (6)、2008年3月25日，甲公司收到乙公司分派的2007年度现金股利 (7)2008年12月31日，乙公司因持有的可供出售金融资产公允价值上涨而确认资本公积180万元；2008年度，乙公司亏损800万元。 (8)2008年12月31日，甲公司判断对乙公司的长期股权投资发生减值，经测试，该项投资的预计可收回金额为5200万元。 (9)2009年2月10日，甲公司将持有乙公司股份中1500万股转让给其他企业，收到转让款4000万元存入银行，另支付相关税费5万元。由于甲公司对乙公司的持股比例已经降至5％，不再具有重大影响，假定乙公司的股份在活跃市场中没有报价，公允价值不能可靠计量。 (10)2009年3月20日，乙公司股东大会通过决议，宣告分派2008年度现金股利500万元。 (11)甲公司与乙公司的会计年度及采用的会计政策相同，不考虑所得税的影响。除上述交易或事项外，甲公司和乙公司未发生导致其所有者权益变动的其他交易或事项。根据以上资料，回答下列问题。
