  • 第3题:

    类Test定义如下,将下列______方法插入③行处是不合法的。 ( )①public class Test{②public float Method(float a,float b){}③④}

    A.public float Method(float a,float b,float c){}

    B.public float Method(float c,float d){}

    C.public int Method(int a,int b){}

    D.private float Method(int a,int b,int c){}


    正确答案:B
    解析:该题考查的方法重载。在 Java程序中可以在同一个类中定义多个名称相同的方法,然而这些方法的参数数量和类型却不完全相同,这种现象被成为方法重载。在本题中,选项A是正确的,虽然它的参数的类型和第二行的参数类型相同,但是它的参数数量是不同的;选项B不正确,它的参数类型和参数数量都和第二行的相同;选项C正确,它的参数类型和第二行的参数类型不同;选项D也正确,它的参数类型和数量都不和第二行的相同。

  • 第4题:

    类Test定义如下,将下列哪个方法插入③行处是不合法的( )?

    ① public class Test{

    ② public float Method(float a,float B) { }

    ③ ______

    ④ }

    A.public float Method(float a,float b,float C) { }

    B.public float Method(float c,float d){ }

    C.public int Method(int a,int B) { }private float Method(int a,int b,int C) { }

    D.private float Method(int a,int b,int C) { }


    正确答案:B
    解析:本题主要考查方法重载,方法的重载是指多个方法可以享有相同的名字,但参数的数量或类型必须不相同(采用不同的形式参数列表),选项B不符合方法重载的要求。

    According to the passage, pocket calculators _____.
    A

    will help students think fast

    B

    will make math too easy for them

    C

    will do harm to students’ thinking ability

    D

    will contribute to the spread of new technology


    正确答案: B
    解析:
    题干中所提到的“pocket calculators”出现在文章第一段中。根据文章第二段第一句中的“this”可知,第二段中提到的科技的负面影响应该在第一段也出现过。所以袖珍计算器对学生的影响应该是负面的,故答案为C项“对学生的思考能力有害”。

  • 第11题:

    填空题
    People have difficulty snapping negative loops of thinking because trying to think about something new in the brain is more difficult than keeping a built path.____

    正确答案: F
    解析:
    根据题干信息“difficulty snapping negative loops of thinking”可以定位到F段“The pathway has been established and it’s just easier to continue following it than trying to think about something new and form a new connection in the brain.”,由于思维已经形成,保持它比在大脑中试着想象新的事情、形成新的连接更容易,故匹配段落为F。
