参考答案和解析
正确答案: B
解析: 参考译文:和许多项目经理一样,Ravi研究了作为主要软件生命周期过程的瀑布模型。他打算在首个任务,也就是即将开始的项目中使用瀑布模型。但是,他发现瀑布模型不能满足要求,原因是客户希望软件分阶段交付,也就意味着系统必须一部分一部分地交付和构建,而不是作为一个整体进行。这种情况在很多其他项目中也类似。现实世界中,很难有一种标准的过程或在前期的项目中使用的过程作为目前项目的最佳选择。对于大部分情况,必须对已存在的过程进行调整,以适应新的问题。但是,即使经过调整,一个开发过程也很难处理变化的需求。为了适应变化的需求而不失去对项目的控制,你必须用需求变更管理过程从而对开发过程进行补充。

    问答题
    Practice 2  Henry Ford did not invent the automobile, but he was the first man to mass-produce it, and this made it available to the ordinary man. Many automobiles were being built by the hand at the turn of the century and were much too expensive for all but the wealthy. In 1903 Henry Ford's first mass-produced Model T cars cost $850. By the early 1920s he was able to reduce the price, to $350. Between 1903 and 1927 Ford manufactured 15 million Model T Fords and earned a profit of $700 million. In 1927 he produced his sedan Model A, which was much more comfortable than the open, windswept Model T.  Henry Ford was himself a born mechanic and could build a car with his own hands. So he respected his workers and treated them well. In 1914, when the basic wage for an industrial worker in Detroit was $11 a week, Ford announced that he would pay his Workers $5 a day. Ford believed in the dignity of work, and did not wish his men to become underpaid robots. He also built them a special town on the outskirts of the city.

    正确答案: 【参考译文】
    汽车不是亨利·福特发明的,但他却是使用机器大量生产汽车的第一人,从而使普通老百姓也能拥有汽车。在20世纪初,许多汽车是手工制造的,对于除富人以外的所有其他人来说,其价格实在太贵。1903年,亨利·福特第一批大量生产的T型汽车每辆卖850美元。到20世纪20年代初,他却能把价格降到350美元。1903年至l927年期间,福特制造了1500万辆T型福特车,赚取7亿美元的利润。1927年,福特生产出A型轿车,比敞篷式不挡风的T型车舒服得多。
    亨利·福特是天生的汽车机修师,他能用双手造出汽车。所以他尊重工人,并善待他们。1914年,底特律产业工人的基本工资是每周11美元,而福特却宣布他给工人的报酬是每天5美元。他信奉工作是高尚的,不希望他的工人沦为收入低下的苦力。他还在底特律郊区专门为他们建造了一个镇子。
