电压表与电流表结构区别是什么?为什么这样设计? 实际的电压表电流表在分析电路时应如何处理 电路中对电流表和电压表简化处理时应把哪个表看成断路? 草履虫等单细胞生物不具有的层次是什么 送好评咯 送好评啦咯 送好评咯哦 又送好评咯 送好评咯!快点啊! 为什么数显电流表和数显电压表不能同时使用我用的是DC20V,DC10A的电流表,电路无任何问题,电流表和电压表采用单独供电! 草履虫的消化场所（ ）A细胞壁 B细胞质 C细胞泡 D伸缩泡 草履虫有没有系统 I hope you ____(be) able to go there I had to wait until he came back改为一般疑问句 I hope go to Canda and work there(改为同义句） MR COATRS HAD TO WAIT TILL OTHER WORKERS CAME TO WORK AND FOUND HIM帮忙翻译下 用vb编写程序代码,题目是输入20个英文单词,统计期中以D字母（大小写均可）的单词有多少个? There was nothing to do（ ） wait until he came back.A.butB.but to可是but前面是to do,根据平行结构,后面也应该是but to wait 为什么选A呢? 连词成句 right hope go to we there now为什么有个right嘞?难道是语气词?Right,we hope to go tothere now .这样... 用vb编写程序代码,题目是输入20个英文单词,统计期中以D字母（大小写均可）结尾的单词有多少个? 1.I hope to go to France some day____there are many famous art museums.A.when B.if C.where D.because为什么不选C啊 根据句意,用方框中所给词的适当形式填空.January 1st,woman,twenty-four,one,fourth,two to two,eleven,hundred 1.The ()month of the year is November.2.() is New Year'Day.3.March 8th is () Day.4.There are () hours in a day.5.Sunday is the Tony can speak borh chinese and English.（chinese and English）是划线的.【就画线部分提问】 as children they are taught to be on time to go to school,to work and to do everything 缺词填空 As children they are taught to be ______ time to go to school,to work and to do everythin ACM的问题我们希望在求出两个数最大公约数的同时还能得到一个方程的解.ax + by = (a,b),（a,b）是a和b的最大公约数这个方程是一定有解的,我们可以求出其中的一组.当 a 和 b 互质的时候,方程有 ACM要怎么搞?我现在才大一,刚学了点东西.如果想发展ACM,那我现在该怎么做?从哪里开始呢.就是怎么提高,看什么材料? ACM怎么提高啊 电压表在电路中测电阻两端电压原理 ----＿＿＿＿＿＿ ----Yes,I'd like that.A would you like to have a picnic B Doyou like eggs?C MayI speak to Tom? 求党的知识问答500题及答案,急 I (speak/speaks) Chinese and English.
