Passage Three
The state of California had to turn off the electricity to almost two million homes and businesses. The state ran out of power.
No one knew when the power would be turned off. People got trapped between floors in an elevator. Firefighters had to save them. These blackouts moved around the San Francisco area. Turning off traffic lights could cause accidents.
Rolling power outages shut down sections of communities across much of northern California, an hour and a half at a time.
People found out it is hard to work without power. Computers don’t work. Locked doors don’t open from a distance.
There has been a power crisis for the past two months. The amount of power isn’t enough to keep up with demand. Debt-ridden utilities couldn’t get suppliers to sell them electricity on credit.
Thursday’s crisis was blamed, in part, on a lack of water for hydropower in the Pacific Northwest.
Now California is trying to legislate a solution with a dozen emergency bills making their way through the state legislature. The state would buy power at long term low rates, and sell it at cost to utilities.
Not all Californians are sure that the power crisis is real. They think that power companies want to get more money.
Political leaders are sure they’ll have a legislative fix by February. Still the crisis won’t really be over until new power plants are working.

A:that there is no real energy crisis B:that the energy crisis is real C:that the utilities are working to fix the problem D:that his business doesn't need power

窗体上有一个名称为Text1的文本框，一个名称为Command1的命令按钮。窗体文件的程序如下： Private Type x a As Integer b As Integer End Type Private Sub Command1_Click（　） Dim y As x y.a=InputBox("") If y.a/2=y.a/2 Then y.b=y.a*y.a Else y.b=Fix(y.a/2) End If Text1.Text=y.b End Sub 对以上程序，下列叙述中错误的是（）。

A:x是用户定义的类型 B:InputBox函数弹出的对话框中没有提示信息 C:若输入的是偶数，y．b的值为该偶数的平方 D:Fix(y.a/2)把y.a/2的小数部分四舍五入，转换为整数返回
