说一个绝处逢生的故事. Magic 做名词Magic作名词是可数名词,还是不可数名词?明天就考试了. 一质量为m的小球随一长为L的轻杆绕O点做角速度为w的匀速圆周运动,最高点时,轻杆对小球有向上的作用力,1.求线速度2.求角速度范围3.求从最低点到最高点这半周内杆对小球的平均功率注：这 哪种电饭煲保温功能比较持久? —I would like to buy an expensive camera.—Well,—I would like to buy an expensive camera.—Well,we have several models .A.to choose from B.to chooseC.to be chosen D.for choice I would like to buy an expensive camera.well ,we have several models ().A.to be chosen B.to choose fromC .to choose D .for choosing5 为什么d不行, Do you have any idea _____ English is used?Well,English is an international language.It is uesd in many countries in the world.A.where B.how C.what D.why I have___to buy his expensive gift for my mother,but i don't like it's____A.enough money;personal enough B.enough money,enough personalC.money enough,enough personal D.moeny enough,personal enough Give her the opportunity to love with the grown of i 可以这么用吗 I would like a camera for Christmas.(对a camera提问） Do you know I'm so alone that you can't feel?这句话对吗?不对该如何修改?这句话的大意是 我非常孤单你感觉到了吗？ i need you by my side Irealy need you by my side 翻译成中文 As long as we have the will to live..”“Don’t…give up…Hope……”是什么意思如题 I wanna need you by my side 如题.这句话该怎样理解?
