  • 第1题:

    下列程序的运行结果是( )。 public class Sun { public static void main(String args[ ]) { int number,digits; number=53; if(number<10) digits=1; else if(number<100) digits=2; else digits=3; System.out.println(digits); } }

    A.1

    B.2

    C.3

    D.0


    正确答案:B
    解析:本题考查对if-else条件语句的理解。本题是if-else语句的嵌套,首先number=53,不满足number10,执行else部分,else部分是嵌套的if-else语句,满足number100,所以digits=2。故本题答案是B。

    问答题
    判断下列命题的真假,并说明理由。  (1)如果(A∨C)⇔(B∨C),则A⇔B;  (2)如果(A∧C)⇔(B∧C),则A⇔B;  (3)如果﹁A⇔﹁B,则A⇔B。

    正确答案:
    (1)假。因为当A⇔1,B⇔0,C⇔1时,满足条件(A∨C)⇔(B∨C),但A⇔B不成立,所以该命题为假。
    (2)假。因为当A⇔1,B⇔0,C⇔0时,满足条件(A∧C)⇔(B∧C),但A⇔B不成立,所以该命题为假。
    (3)真。因为A⇔﹁(﹁A)⇔﹁(﹁B)⇔B,所以该命题为真。

    At a college basketball game, the ratio of the number of freshmen who attended to the number of juniors who attended is 3:4. The ratio of the number of juniors who attended to the number of seniors who attended is 5:6. What is the ratio of the number of freshmen to the number of seniors who attended the basketball game?

    E

    1:3


    正确答案: D
    解析:
    Freshmen to Juniors is 3:4. and Juniors to Seniors is 5:6. Since the least common multiple of 4 and 5 is 20. multiply the terms of the first ratio by 5 and the second one by 4. Then the ratio of freshmen to juniors to seniors is l5:20:24. Therefore, 15:24 is the ratio of freshmen to seniors. 15:24=15/24=5/8

    A die whose faces are numbered from l to 6 is rolled. Which of the following statements must be true?Ⅰ. The probability of getting a 4 on the top face is 2/3.Ⅱ. The probability of getting an odd number on the top face is 1/2.Ⅲ. The probability of getting a prime number on the top face is 1/2.
    A

    Ⅰand Ⅱ only

    B

    Ⅱ and Ⅲ only

    C

    Ⅰ and Ⅲ only

    D

    Ⅱ only

    E

    Ⅰ, Ⅱ, and IⅢ


    正确答案: E
    解析:
    There are total six different results when the die is rolled. Since any one of the six numbers many show up on the top face, the probability of getting a 4 on the top face is 1/6. Hence, Roman numeral Ⅰ is not true. Statement Ⅱ is true. Since there are three prime numbers, the probability is 3/6 or 1/2. Hence, Roman numeral Ⅲ is true.
