问题1:在窗体上有一个命令按钮Commandl,编写事件代码如下:Private Sub Command1_Click()Dim x As Integer,y As Integerx = 12:y = 32Call Proc(x,y)Debug.Print x; yEnd SubPublic Sub Proc(n As Integer,ByVal m As Integer)n = n Mod 10m = m Mod 10En
程序运行后,显示2 32.所以应选择A
本题的主要考点是传值与传址.
子过程proc()中,n默认的是传址格式,即x的地址赋予n后,n变为12,在子过程中n运算后值为2,过程结束后,将n的地址再传回x,故x显示为2;
子过程proc()中,m前加了Byval,即定义其为传值格式.虽然将y的值赋予了m,m变为32,在子过程中m运算后值为2,过程结束后,m的值不对y值构成影响,故y仍为其初始值32.
回答完毕!
问题2:22度18分乘590度减57度23分27秒[数学科目]
22°18′x5=22°x5+18′x5=110°+90′=110°+1°+30′=111°30′=111.5°

问题3:1.根据有关规定:小汽车在城市街道上的行驶速度不得超过70km/h,如图所示,测速站M到马路L的距离MN为30m,一辆小汽车在马路L上由东向西行驶,测得此车从A点行驶至B点所用的时间为2秒,并测得∠A[数学科目]
∵∠AMN=60°, ∠BMN=30°
∴ ∠BMA=30°
∵∠AMN=60°, ∠BNA=90°
∴∠BAM=30°
∴∠BAM=∠BMA
∴BA=BM
在直角三角形BNM中,∠BMN=30°
∴BM=2BN
设BN=x m ,则BM=2x m ,
由勾股定理得,x2+ 302=(2x)2,
∴x=10√3 ∴BN=10√3 m, AB=BM=20√3m
速度:10√3m/s=17.32m/s
70km/h=19m/s
∴没超速
