    x, y, and z are positive integers. Which of the following lists all the possible ways for x + y + z to be an odd number?I. One of the numbers is odd.II. Two of the numbers are odd.III. Three of the numbers are odd.
    A

    I

    B

    I and II

    C

    I and III

    D

    II and III


    正确答案: C
    解析:
    I. One of the numbers is odd. Let x be odd. Let y and z be even. y + z is even. An even plus an odd is odd, so x + y + z is odd.

    If 7y+9 represents an odd integer, which of the following represents the next smaller odd integer?
    A

    7(y+1)

    B

    7(y-2)

    C

    7(y+3)

    D

    7(y+2)

    E

    7(y-2)+1


    正确答案: A
    解析:
    根据奇整数的排列顺序特点,相邻两奇整数之差为2,因此比7y+9小的相邻奇整数为(7y+9)-2=7y+7=7(y+1)。

  • 第15题:

    Sequential circuit is a common logic device whose output values, at a given instant, depend upon its input values and the internal state at that instant, and whose internal state depends upon the(66)preceding input values and the preceding internal state. A sequential circuit can assume a finite number of internal states and may therefore be regarded, from an abstract(67), as a finite(68).Combinational circuit is another logic device whose output values, at any given instant, depend upon the input values at that instant. A combinational circuit is a(69)of a sequential circuit whose internal state is not taken(70).

    A.directly

    B.immediately

    C.instantly

    D.snapshot

    If a and b are integers and the sum of ab and b is even, which of the following could be true?Ⅰ. a and b are both odd.Ⅱ. a is even and b is odd.Ⅲ. a is odd and b is even.
    A

    Ⅰ only

    B

    Ⅱonly

    C

    Ⅲ only

    D

    Ⅰ and Ⅱ

    E

    Ⅰand Ⅲ


    正确答案: C
    解析:
    Plug-in. StatementⅠ:if a and b are both odd, says a=1 and b=3, then ab+b=6. Since the sum is even, statementⅠ is true. StatementⅡ:1et a=2 and b=3, then ab+b=9. Since the sum is odd, this statement is false. Statement Ⅲ:let a=3 and b=2, then ab+b=8, which is even. So both statement Ⅰand statementⅢ are true.

    C

    a + 2b

    D

    ba

    E

    (ab) a


    正确答案: D
    解析:
    An odd number raised to an even power equals an odd number. Take 32 = 9, for example, ba is the correct answer.

    D

    What serious a problem


    正确答案: B
    解析:
    句意:无论有多么严重的问题,你都应该鼓起勇气面对。引导让步状语从句,用“疑问词+ever”相当于“no matter+疑问词”,意为“无论…”。形容词应放在连词之后。故答案是C项。
