请认真阅读下面各题,从题中所给的A、B、C、D四个选项中,选出最佳选项,并在机读卡上将该项涂黑。

I was walking down the road one day when my cell phone rang.  36 voice on the other end spoke to me, "Dad, please come back soon.I miss you so much! "I judged that it was a   37_ number.A little while later, the call came once again, so I rudely   38  , "You've dialed the wrong number! " and then   39

During the following days, I got the same call   40  .But I didn't care much about it.

Then one day she constantly called me,   41  I didn't answer.Finally I answered the phone and heard a weak voice, "Dad, please come back.I miss you so much!  Dad, I'm   42  so much pain! Mom said you were too busy to take   43 of me.But, dad, please   44 me again, OK?" The innocent   45 was difficult to reject.I made a   46 kiss on the phone and heard the weak voice say, "Thank you...Dad, I am so...happy, so...happy..."

Shortly after this, I became   47  about who had been on the other end of my phone.So I called back, and a woman answered, "Sorry, sir.I am really sorry to have   48  you.My daughter has suffered from bone cancer   49  she was born.And her father...died in an   50  a short while ago.I dare not tell her this   51  .Poor baby.When she couldn't   52 the painful chemotherapy(化疗), she would cry for her dad, who had always   53 her.I really couldn't bear it, so I gave her a random phone number..."

"How is your daughter now?" I couldn't wait to   54

"She has   55  .You must have kissed her on the phone, because she went with a smile, tightly holding the cell phone..."

Tears blurred my eyes...

题型:实验题

(Ⅰ)(原创)环境的污染日趋加重,汽车行业目前开始推行混动版(燃油与电动力搭配)家用汽车,电动力输出以锂离子电池组为核心,它由多个电池单元组成。下面是正在研制的一种新型电池单元,某同学在测定电源电动势和内电阻的实验中,测得多组电压和电流值,得到如图所示的U-I图线.

由图可求出该电源电动势E ="______" V;内阻r ="______" Ω。

(Ⅱ)某同学要测量一均匀新材料制成的圆柱体的电阻率ρ。步骤如下:

(1)先用多用电表对电阻大小进行粗测,选用欧姆档的“×10”档位,按正确的操作步骤测此圆柱体的电阻,表盘的示数如图,则该电阻的阻值约为    Ω。 

(2)该同学想用伏安法更精确地测量其电阻R,现有的器材及其代号和规格如下:

待测圆柱体电阻R

电流表  A1(量程0~3 mA,内阻约50 Ω)

A2(量程0~30 mA,内阻约20 Ω)

电压表  V1(量程0~3 V,内阻约10 kΩ)

V2(量程0~15 V,内阻约25 kΩ)

直流电源E(电动势4 V,内阻不计)

滑动变阻器R1(阻值范围0~10 Ω,允许通过的最大电流2.0 A)

开关S  导线若干

据题意,该同学应选择电流表、电压表的代码分别是    ; 

(3)如果既要满足测量要求,又要使测量误差较小,应选择如图所示的四个电路中的____;

(4)若待测电阻的测量长度用l表示,直径用D表示,加在电阻两端的电压用U表示,通过电阻的电流用I表示,则此圆柱体材料的电阻率表达式为ρ=
