Robert Kohout,39,was working outside his home last October when he heard a frightening noise．He turned round and saw Walter Graham' s car sinking into 8 feet of water of the swimming pool a little distance away from his yard．
Kohout immediately called to Graham' s wife, Evelyn, to telephone 911．Then he ran back to his house to get Terence Reif and Glenn Fajardo to help ,who were at work inside the house． "There was no time for second thoughts," said Reif, a farmer's son．"The only thing to do was to get in the pool．"
The car doors were locked．Graham,73,was unconscious(失去知觉), and his Mercury was rapidly filling with water．Reif struggled to break the driver' s side window with a hammer but had trouble getting it done underwater．
Finally--some four minutes after the car had fallen into the pool--the glass was broken．By then,Graham was floating at the top of the flooded passenger compartment(车厢)．
The three men pulled Graham out through the broken glass．He wash' t breathing and his heart stopped beating, so they performed mouth-to-mouth resuscitation．The rescue (急救) team arrived in no time．Doctors supplied him with advanced life support on the way to the hospital．
"These people were getting to Graham through the glass," said Dr．Jeff Messinger．"All three acted without regard for their own safety．" Added Evelyn Graham, "They were truly angels ( 天使) watching over US．”
What does the word "resuscitation" refer to in the story?
A.Awayofsavingpeoplewhohavestoppedbreathing
B.Awayofhelpingpeoplewhohavehearttrouble
C.Awayofsavingpeoplewhohavegotdrunk
D.Awayofhelpingpeoplewhoneedwater

Q：对于柔性电子器件，如何权衡柔性与机械性能之间的关系？如何在增加机械稳定性的同时保证器件的柔性，尤其是在与处理电路配合的条件下?
A：这个问题实际上是如何在软、硬界面之间实现最小化的应力分布，即处理电路芯片与软的硅胶聚合物封装层之间存在机械性能不匹配的问题，如果不降低应力分布，会导致器件分层和失效。近年来，一些研究人员对此展开了研究，例如采用梯度结构来缓解器件从刚性到柔性的急剧转变。在我们的工作中，则是将这类电路芯片嵌入流体或者超软聚合物之中，使得芯片半悬空与衬底之上，来降低应力分布不均造成的影响。   A. 对 B. 错
