第1题：

在窗体中有一个命令按钮Commandl，编写事件代码如下：
Private Sub Command1_CliCk()
Dim s As Integer
s=P(1)+P(2)+e(3)+P(4)
debug．Print S
End SUb
Public Function P(N AS Integer)
Dim Sum As Integer
Sum=0
For i=1 To N
Sum=Sum+i
Next i
P=Sum
End Function
打开窗体运行后，单击命令按钮，输出结果是
A．15
B．20
C．25

单选题
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.
第5题：

问答题
x, 2y, and 2z-1 are consecutive integers.

正确答案： B
解析：
因为x，2y，2z-1是三个连续数字，所以2z-1>2y，所以z-y>1/2>0，所以A小于B，故本题选择B项。

单选题
al, a2, a3, a4, as, …., anIn the sequence of positive integers above, al = a2 = 1, a3 = 2, a4 = 3, and as = 5. If each term after the second is obtained by adding the two terms that come before it and if an = 55, what is the value of n?
A
12
B
10
C
9
D
8
E
5

正确答案： A
解析：
Following the given rule for obtaining terms, write the terms of the sequence up to and including 55: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 Since 10 numbers are listed, n = 10.

How many positive integers less than 70 are equal to the product of a positive multiple of 5 and an even number?
A
4
B
6
C
9
D
10
E
11

正确答案： D
解析：
All even multiples of 5 must be multiples of 10. So the multiples of 10 between 0 and 70 are 10, 20, 30, 40, 50 and 60. That’s 6 altogether.
第12题：

单选题
If a and b are positive integers such that (a-4)(b-5) = 0, what is the least possible value of a + b?
A
5
B
6
C
8
D
10
E
11

正确答案： E
解析：
如果(a-4)(b-5) = 0，所以(a-4) = 0或(b-5) =0，或两者都等于0，a = 4 或b = 5.，如果要使a + b的值最小，我们应该假设a=4，那么b可以为任何值，又因为b的值为正整数，所以b的最小值为1，所以a + b最小的可能值为4+1=5。

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 m and n are positive integers and 3m+n-1=2m+2n, which of the following must be true?I. m and n are consecutive integers.II. m is even.III. n is odd.
A
None
B
I only
C
II only
D
III only
E
I, II, and III

正确答案： D
解析：
Since m=n+1, where m and n are given as positive integers, Roman numeral choice I is true. Since, m=n+1, m can be either odd or even, hence choice II is false. Roman numeral choice III is also false since n can be either even or odd.
第21题：

单选题
Let Ω p be defined as p2/3-p for all positive integers, p. If Ωn = s, and s is a positive integer, which of the following is a possible value for s?
A
1
B
3
C
5
D
6
E
8

正确答案： D
解析：
根据题干Ωn =n²/3-n=s. n为正整数，且s为正整数；根据函数可知只有当n是3的倍数时，s才能为整数，否则如果n²/3不是整数，s也不是整数。现在可以从符合条件的n的最小值3代入到函数中。当n=3时，n²/3-n =3²/3-3 = 3-3 = 0 = s；当n=6时，n²/3-n = 6²/3-6 = 12-6 = 6 = s。所以故选D。
