若点P在椭圆上运动，点M(m，0)在长轴上，求PM

为什么"There will be a computer on every desk in the furure"中"will"后加"be"而不是加"have"是不是因为"will"后面加动词原形,而"have"不是动词原形所以加"be"?那么除了加"be"外可不可以加别的词?注：解答这请 物理的串反并同是什么意思 谁能帮我翻译一下bounce的歌词（机器翻译不要）i ain't gonna take this no morebounce baby out the doorget up and move don't make me act a fooljust bounce baby out the doorbounce baby out the doori ain't gonna take this no morebounce b eighty-six是什么意思? 英语翻译如题. 一道物理题,请速回,一小车的表面由一光滑水平面和光滑斜面连接而成,其上方以求,球与水平面的接触点为a,与斜面的接触点为b,当小车和球一起在水平桌面上作直线运动时,下列结论正确的是 如图所示,地面上的人通过定滑轮用轻绳将质量为m=40Kg的演员从静止开始沿竖直方向向上拉起,演员先做匀加速直线运动再做匀减速直线运动直到静止,演员加速运动与减速运动过程中的加速度 eighty的汉语是什么意思 eighty是什么意思?
