      On May 27, 1995, our life was suddenly changed. It happened a few minutes past three,   1   my husband,
Chris, fell from his horse as it jumped over a fence. Chris was paralyzed (瘫痪) from the chest down, unable to
breathe normally. As he was thrown from his horse, we entered into a life of   2   with lots of unexpected
challenges. We went from the "haves" to the "have-nots". Or so we thought.    
       3   what we discovered later were all the gifts that came out of sharing difficulties. We came to learn that
something wonderful could happen in a disaster (灾难). All over the world people   4   Chris so much that letters
and postcards poured in every day. By the end of the third week in a medical center in Virginia, about 35,000
pieces of   5   had been received and sorted.   
      As   6  , we opened letter after letter. They gave us comfort and became a source of strength for us. We
used them to   7   ourselves. I would go to the pile of letters marked with "Funny" if we needed a   8  , or to the
"Disabled" box to find advice from people in wheelchairs or even in bed living happily and successfully.   
      These letters, we realized, had to be shared. And so here we offer one of them to you.
Dear Chris,   
       My husband and I were so sorry to hear of your   9   accident last week. No doubt your family and your
friends are giving you the strength to face this   10   challenge. People everywhere are also giving you best
wishes every day and we are among those who are keeping you close.  
                                          Yours Sincerely,                                                                                                                                                                        Nancy Reagan

小杨和小亮手中都拿着一截电炉丝,小杨说:“可能我这截电炉丝的电阻较大,因为它比较长”,小亮说:“也可能我这截电炉丝的电阻较大,因为它比较细.”他们决定通过实验来测量各自电炉丝电阻的大小.(估计两截电炉丝的电阻都不超过10Ω)

(1)请在方框内画出“伏安法测电阻”电路图.

(2)小杨连接的实验电路如图甲所示,经检查发现有两处错误,请你将这两处错误写出来:① _________ ;② _________

(3)小杨改正了电路中的错误,开始实验.闭合开关后,观察到电流表和电压表的示数如图乙所示.于是,小杨就根据测得的这一组数据:电流表的示数为 _________ A,电压表的示数为_________V,算出了他拿的电炉丝的电阻为_________Ω.

(4)小亮在实验中正确连接电路后,先测得四组数据并通过求平均值的办法算出他拿的电炉丝的阻值为7.8Ω.你认为他们的测量结果哪个更好?为什么?
