在窗体中添加一个名称为Command1的命令按钮,然后编写如下事件过程。
Private Sub Command1_Click()
For i=1 To 4
x=4
For j=1 To 3
x=3
For k=1 To 2
x=x+6
Next k
Next j
Next i
MsgBox x
End Sub
窗体打开运行后,单击命令按钮,则消息框的输出结果是( )。

A) 7
B) 15
C) 157
D) 538

答案

参考答案:B

解析: 本题考查循环程序。需要有耐心的过一遍程序,这样就会发现,不论第l层运行多少次,总会把x还原为4,所以就只看最后一次的结果,相当于第一层只运行1次。同理第2层也总会把x还原为3,所以也只看最后一次的运行结果,相当于第2层也只运行一次,x赋初值3,当j=1,k=1时,x=3+6;当j=1,k=2时x=9+6=15。所以答案选B)。

Healthy knees aren't the main consideration in choosing high heels, but new research says chunky heels are just __________as spindly stilettos (细高跟鞋).  

"It takes a long time to feel the effects of knee osteoarthritis (骨关节炎) — and once you do, it is too ]ate," said Dr. Casey Kerrigan, leading researcher of the study and associate professor at Harvard Medical School's department of physical medicine.

"I compare it to smoking — one cigarette is not painful, but over a lifetime it is. Wide-heeled shoes feel comfortable, so women wear them all day long, "Kerrigan said. "They are better for your feet than stiletto heels, but just as had for your knees."

The idea that high heels are bad for your health isn't new — scientists have warned women for years that they contribute to problems ranging from corns to hammer toes, tendonitis, knee pain, sprained (扭伤) ankles and back problems. 

But in 1998,Kerdgan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis, a painful joint disease that destroys cartilage (软骨) surrounding the knee.

The first study looked only at stiletto heels, and Kerrigan said she wanted to study the chunky high-heeled shoes she noticed many women wearing.

"This study confirms what we all intuitively (直觉地) know that high-heeled shoes of any kind are not good for our health," said Dr. Glenn Pfeifer, a San Francisco doctor and member of the American Academy of Orthopaedic Surgeons who was not connected to the study.
