  • 第13题：

    public class Something {

    public static void main(String[] args) {

    Something s = new Something();

    System.out.println("s.doSomething() returns " + doSomething());

    }

    public String doSomething() {

    return "Do something ...";

    }

    }

    看上去很完美。


    正确答案：

     

    错。看上去在main 里call doSomething 没有什么问题，毕竟两个methods 都在同一个

    class 里。但仔细看，main 是static 的。static method 不能直接call non-static methods。可改

    成"System.out.println("s.doSomething() returns " + s.doSomething());"。同理，static method 不

    能访问non-static instant variable。

  • 第14题：

    阅读以下说明和Java程序，将应填入(n)处的字句写在对应栏内。

    [说明]

    下面程序输出一个矩形面积，以及矩形区域上的假想的作物产量。

    [Java程序]

    public class MainJava {

    Lot_size small=new Lot_size();

    Lot_size medium=new Lot_size();

    small.set(5,5,5，25);

    medium.set(10,10,10,50);

    System.out.println("For a small lot of area"

    +small.get_area()+"\n");

    System.out.println("the actual crops are $"

    +small.get_data2()+"\n");

    System.out.println("and ideal crops are $"

    +small.get data()+"\n");

    System.out.println("For a medium lot of area"

    +medium.get_area()+“\n”)；

    System.out.println("the actual crops are $"

    +medium.get_data2()+"\n");

    System.out.println ("and ideal crops are $"

    +medium.get_data()+"\n");

    }

    }

    class Crop_assessment{

    private int actual_crop;

    private int ideal_crop;

    public void set(int in_actual,int in ideal){

    actual_crop=in_actual;

    ideal_crop=in_ideal;

    }

    public int get_actual_crop(){return (1) ;}

    public int get_ideal_crop()(return (2) ;}

    }

    class Lot_size{

    private int length;

    private int width;

    private Crop_assessment crop= (3) ;

    public void set(int 1,int W,int a,int i){

    length=1;

    width=W;

    crop.set(a,i);

    }

    public int get_area(){return length*width;}

    public int get_data()freturn (4) ;}

    public int get_data2()(return (5) ;}

    }


    正确答案：(1) return actual_crop (2) return ideal_crop (3) new Crop_assessment() (4) crop.get_ideal_crop (5) crop.get_actual_crop()
    (1) return actual_crop (2) return ideal_crop (3) new Crop_assessment() (4) crop.get_ideal_crop (5) crop.get_actual_crop() 解析：本题以Java语言为载体，考查面向对象程序设计中的几个重要概念—类的嵌套及函数的使用。
    本题的功能是通过已定义的粮食收成类定义了一个计算特定矩形域上粮食收成的类，在主函数中定义了两个对象，并调用了相应的函数，来输出理想和实际的粮食产量。
    首先，由于Crop assessment定义的成员数据缺省为私有的，所以想要获得实际和理想的粮食产量，要通过两个公有成员函数，所以(1)处应填入“return actual_crop”，(2)处应填入“return ideal_crop”。
    其次，在类Lot size中，由于我们要反映矩形域上的粮食产量，所以我们在类中嵌套定义了一个类，Java中对象需要实例化，故(3)应填入“new Crop_assessment()”。
    最后，由于我们想通过Lot_size类中的get_data和get_data2函数得到粮食产量，但由于这两个成员数据是私有函数，所以我们必须通过定义的对象调用它，所以(4)应填入“crop.get_ideal_crop()”，(5)应填入“crop.get_actual_crop()”。

    was by no means a rare occurrence

    C

    attracted a lot of public attention

    D

    C

    D

    正确答案： D
    解析：
    cheer up意为“欢呼”。grow light意为“变明亮”。get dark意为“黑暗”。均不符合题意。由后文可知，是作者错了，是作者自己的窗户脏了。故选项A“我开始明白了”符合题意。

    The underlined word “assemble” in the second paragraph probably means ______.
    A

    to bring a group of people together in one place for a particular purpose

    B

    to make a public or official statement, especially about a plan, decision

    C

    to produce many copies of a book, magazine, or newspaper

    D

    not to take part in an event or not to buy or use something as a protest


    正确答案： A
    解析：
    词义题。从文章的第二段第二句话“In 1848 the leaders of this movement (some of whom were antislavery activities as well) assembled the first Women’s Rights Convention，demanding equality. ”可知，由于美国的妇女没有多少权利可言，她们准备发动运动来请愿。这里的assemble的意思就是“为了一定的目的而聚集在一起”。所以本题的正确答案为A。
