I sat down to read under an old tree in the park. I felt my life was   36 , for my whole world was dark.
A young boy ran up to me, out of breath. He stood  37   before me with his head down and said   38 , “Look what I found!” In his hand was a flower, and what a poor sight! The flower was dry and   39 . I gave him a small smile and then turned my eyes away so that he could take his dry flower and go off to play.
  40 , he sat next to my side and placed the flower to his   41  and said in surprise, “It smells sweet and it’s beautiful, too. That’s   42  I picked it. Here, it’s for you. ” The flower before me was dead. But I knew I must   43  it, or he might never leave. So I accepted the flower, and replied, “This is just what I   44 . ” Just then, for the first time I noticed that the boy could not   45  —he was blind.
Tears (眼泪) came down my face as I   46  him for picking the best one. “You’re welcome. ” he smiled, and then ran off to   47 . I sat there and wondered how he was able to learn about my pain (痛苦).
Through the eyes of a blind child,   48  I could see the problem was not with the world; the problem was me. And for all those years I myself had been   49 . I decided to see the beauty in life, and   50  every second of my life. And then I held that dry flower up to my nose and breathed in the smell of a beautiful rose.

(1)要用伏安法测量RX的电阻,已知电压表内阻约几kΩ,电流表内阻约1Ω,若采用甲图的电路,Rx的测量值比真实值______(选择“偏大”或“偏小”),若Rx约为10Ω应采用______(选“甲图”或“乙图”)的电路,误差会比较小.

(2)无论是用甲图或乙图测量,都不可避免产生由电表内阻引起的测量误差,有两个研究性学习小组分别设计了以下的实验方案:

Ⅰ.第一组利用如图丙的电路进行测量,主要实验步骤如下:

第一步:将电键S2接2,闭合电键S1,调节滑动变阻器RP和RW,使电表读数接近满量程,但不超过量程,记录此时电压表和电流表的示数U1、I1

①请你写出接着的第二步,并说明需要记录的数据:______.

②由以上记录的数据计算出被测电阻Rx的表达式为Rx=______.

③简要分析此实验方案为何能避免电表内阻引起的实验误差______.

Ⅱ.第二组同学利用如图丁的电路测量,其中R1 是电阻箱,已知R2=72Ω、R3=100Ω.合上S,当R1未调至图中所示阻值时,灵敏电流计G的指针会偏转,将R1调至如图中所示时,灵敏电流计的指针回到零位.

①在答卷的方框内画出与图丁对应的电路图.

②读出图中电阻箱的阻值R1=______Ω,算出待测电阻的值Rx=______Ω.
