    Every morning,kids from a local high school are working hard．They are making and selling special coffee at a coffee cafe．They are also making a lot of money.
    These students can make up to twelve hundred dollars a day．They are selling their special coffee to airplane passengers．After the students get paid,the rest of the money goes to helping a local youth project.
    These high school students use a space in the Oakland airport．It is usually very crowded.
    Many people who fly on the planes like to drink the special coffee.
    One customer thinks that the coffee costs a lot but it is good and worth it．Most customers are pleasant but some are unhappy．They do not like it if the coffee care is not open for business.
    The students earn$6.10 an hour plus tips．They also get school credit while they learn how to run a business．Many of the students enjoy the work although it took some time to learn how to do it.
    They have to learn how to steam milk,load the pots,and add flavor．It takes some skill and sometimes mistakes are made．The most common mistake is forgetting to add the coffee．

  • 第18题：

    简要介绍Graph图表——WaveformGraph的使用。


    正确答案: 1、当输入数据为一维数组时，Waveform Graph直接将一维数组画成一条曲线，纵坐标为数组元素的值，横坐标为数组索引。
    2、当输入数组为二维数组时，缺省情况下每一行的数据对应一条曲线，即曲线的数目和行数相同。
    3、簇作为输入时需要指定三个元素：起始位置x0、数据点间隔dx和数组数据。
    4、一维簇数组也可以直接作为Graph的输入，此时相当于x0为0，dx为1。
    5、波形数据作为输入时，由于波形数据所携带的数据横轴为时间，因此需要将Waveform Graph的横轴设为时间轴。

  • 第19题：

    简要介绍Graph图表——XY Graph的使用。


    正确答案: 当我们需要画的曲线是由（x，y）坐标决定的时候，我们就需要采用XY Graph。其实Waveform Graph在一定意义上也是XY Graph，但是它的X轴必须是等间距的，而且不可控制。
    1、XY两个一维数组绑定为簇作为输入。
    2、坐标点簇数组作为输入，该方式将各个点的坐标绑定为簇然后作为簇数组输入，和直接将XY数组绑定为簇输入效果一样。但是后者不一定需要XY数组的大小一致，它会自动将大的数组裁剪。
    3、时间作为X轴——利用XY Graph实现历史曲线。
    4、Express XY Graph将Express XY Graph放置在前面板上的同时，在程序框图中会自动添加一个VI，它的XY轴数据为动态数据类型。

    The Employment Prospect in City A As is shown in the graph, the employment prospect in City A appears not so bright. City A Personnel and Talent Bureau reported that in 2001, there were only 50,000 positions available for the almost 60,000 graduates. And the number of the graduates increased by 67 % in the following two years, while that of the job opportunities remained the same.
    In order to solve the problem, the government should adjust job market policies to take pressure off the new job-seekers. For one thing, they’re supposed to provide the graduates with more job opportunities. For another, they should train the graduating college students for the fierce competition ahead.
    It is more important that the job hunters be fully aware of the difficult situation and get fully prepared for the tough journey. If still they cannot find a suitable job, they can choose to put off employment and go abroad for further study.

Since the scores are in order from lowest to highest, simply count over to the middle value to determine the median. The median is the average of the ninth and tenth terms. In this example, both the ninth and tenth terms are 5, so the median is 5.
