    A．two.three.

    B．two.

    C．three.

    D．value is 2


    正确答案：A
    解析：该题测试的是考生对switch语句的掌握，执行时，swish语句根据表达式返回的值与每个case子句的值相比较。如果匹配成功，则执行该case子句后的语句序列，直到执行到break语句或switch语句结束，然后跳出switch语句。如果匹配不成功，则跳转到default语句。本题中的switch(2)应对应case2，所以输出"two."，但是它后面没有break，所以继续执行case2+1，输出"three."，这时遇到break，则跳出switch语句。所以本题选择A。
