Baby One More Time
Britney Spears
(Oh baby baby)
(Oh baby baby)
Oh baby baby
How was I supposed to know
That something was't right here
Oh baby baby
I shouldn't have let you go
And now you're out of sight,yeah
Show me how you want it to be
Tell me baby
'Cause I need to know now
Oh because
My loneliness is killing me
(And I) I must confess
I still believe (still believe)
When I'm not with you I lose my mind
Give me a sign
Hit me baby one more time
Oh baby baby
The reason I breath is you
Boy you got me blinded
Oh pretty baby
There's nothing that I wouldn't do
It's not the way I planned it
Show me how you want it to be
Tell me baby
'Cause I need to know now
Oh because
My loneliness is killing me
(And I) I must confess
I still believe (still believe)
When I'm not with you I lose my mind
Please give me a sign
Hit me baby one more time
(Oh baby baby,Ooh)
(Oh baby baby yay ,ayeah)
Oh baby baby
How was I supposed to know
Oh pretty baby
I shouldn't have let you go
I must confess
That my loneliness is killing me now
Don't you know I still believe
That you will be here
And give me a sign
Hit me baby one more time
My loneliness is killing me
(And I) I must confess
I still believe (still believe)
When I'm not with you I lose my mind
Give me a sign
Hit me baby one more time
I must confess that
My loneliness is killing me now
Don't you know
I still believe
That you will be here
And give me a sign
Hit me baby one more time

Because of you
I will not make the same mistakes that you did
I will not let myself
Cause my heart so much misery
I will not break the way you did,
You fell so hard
I ve learned the hard way
To never let it get that far
Because of you
I never stray too far from the sidewalk
Because of you
I learned to play on the safe side so I don t get hurt
Because of you
I find it hard to trust not only me, but everyone around me
Because of you
I am afraid
I lose my way
And it s not too long before you point it out
I cannot cry
Because you know that s weakness in your eyes
I m forced to fake
A smile, a laugh everyday of my life
My heart can t possibly break
When it wasn t even whole to start with
Because of you
I never stray too far from the sidewalk
Because of you
I learned to play on the safe side so I don t get hurt
Because of you
I find it hard to trust not only me, but everyone around me
Because of you
I am afraid
I watched you die
I heard you cry every night in your sleep
I was so young
You should have known better than to lean on me
You never thought of anyone else
You just saw your pain
And now I cry in the middle of the night
For the same damn thing
Because of you
I never stray too far from the sidewalk
Because of you
I learned to play on the safe side so I don t get hurt
Because of you
I try my hardest just to forget everything
Because of you
I don t know how to let anyone else in
Because of you
I m ashamed of my life because it s empty
Because of you
I am afraid
Because of you
Because of you


I'm just a little bit caught in the middle
Life is a maze, and love is a riddle
I don't know where to go
Can't do it alone
I've tried, but i don't know why
Slow it down, make it stop
Or else my heart is going to pop
Cause its to much, yea its alot
To be something I'm not
I'm a fool, out of love
Cause I just can't get enough
I'm just a little bit caught in the middle
Life is a maze, and love is a riddle
I don't know where to go
Can't do it alone
I've tride, but i don't know why
I'm just a little girl lost in the moment
I'm so scared but i don't show it
I can't figure it out
It's bringing me down
I know, I've got to let it go
And just enjoy the show
The sun is hot in the sky
Just like a giant spot light
The people follow the signs
And sicronise in time
It's just, no body knows
They got to take it to the show
I'm just a little bit caught in the middle
Life is a maze, and love is a riddle
I don't know where to go
Can't do it alone
I've tried, but i don't know why
I'm just a little girl lost in the moment
I'm so scared but i don't show it
I can't figure it out
It's bringing me down
I know, I've got to let it go
And just enjoy the show
Just engoy the show
I'm just a little bit caught in the middle
Life is a maze, and love is a riddle
I don't know where to go
Can't do it alone
I've tride, but i don't know why
I'm just a little girl lost in the moment
I'm so scared but i don't show it
I can't figure it out
It's bringing me down
I know, I've got to let it go
And just enjoy the show
Just enjoy the show
Just enjoy the show
I want my money back
I want my money back
I want my money back
Just enjoy the show
I want my money back
I want my money back
I want my money back
Just enjoy the show

做作业挺辛苦的，

喜帖街！哈哈哈哈

使物体带点的方法~

摩擦起电 ~用摩擦的方法使束缚力较弱的电子发生转移 本来不带电（电子带负电不要告诉我你这都不知道）因为电子带负电的走了所以原先的物体带电了！

接触带电 就是一个物体碰到了一个带电的东西 这个物体去带电的东西那边抢了电过来 然后那个物体就带电了 前提是这个物体要跟带电的物体接触才能抢

感应带电~ 就像磁铁那样 一个铁放在磁铁旁边久了就有一些磁性 感应带电也是这样 一个带电体可以带动旁边的都带上电，

两种电荷
规定用丝绸与玻璃棒摩擦所带的电称为正电荷
因为在摩擦过程中原子失去了电子·~~（个人理解 失去就是减少也就是减去 减去一个带负点的电子 也就是说负负得正~ 减去是一个负号 电子负电是一个负号两个负号就是正号 所以就带上了正电）
负电荷 规定毛皮与橡胶棒摩擦所带的电称为负电荷 ~
因为在摩擦过程中原子得到了多余的电荷 ~（用上面那个观点就是说 得到就是加上 加上一个带负电的电子还是负的所以显负性）

同性相斥 异性相吸~~ 懂吗 正负电的电荷会互相吸引 正正或者负负的电荷在一起会相互排斥。

验电器~ 因为里面装置都是可以导电的 所以如果你带的是负点或者正电放在那边 金属箔应该会像两边分开~ 知道为什么吗 ~ 因为你就导了一种电荷的电 所以就是同性相斥的原理 ~ 如果没有带电的话 金属箔是不会动的。
所以说验电器只能检验物体是否带电 不能检验物体带的是正电还是负点
