Are you a man or a mouse? When people ask this question they want to know     you think you are a     person or a coward (懦夫). But you will never really know the answer to this question     you are tested in real life. Some people    they are brave but when they come face to face with real    , they act like cowards. Others think of themselves as cowards, but when they meet danger, they act like heroes.

Lenny had always thought of himself as a nervous person. He got worried before examinations. He worried about his job and health. All he wanted in life was to be safe and healthy. But    December 15th, 2013, a plane crashed into a river in Washington. Lenny went to the river to see what was happening. He saw a woman in the     water. Lenny did not feel afraid. He behaved very    and did a very dangerous thing. He jumped into the river and    to the woman, and kept her head above the water. Seventy-eight people died that day. Thanks to Lenny, it was not    .

When you are in a very dangerous situation and feel afraid, the body automatically(自动地) produces a chemical in the blood. The chemical is called adrenalin(肾上腺素). With adrenalin in the blood system, you actually feel stronger and stronger and are ready to fight.

普通水泥在固化过程中自由水分子减少并产生Ca(OH)₂，溶液呈碱性。根据这一特点科学家发明了电动势(E)法测水泥初凝时间，此法的原理如图所示，反应的总方程式为：2Cu＋Ag₂O=Cu₂O＋2Ag。下列有关说法不正确的是

A．工业上制备普通水泥的主要原料是黏土和石灰石

B．测量原理装置图中，Ag₂O/Ag极发生氧化反应

C．负极的电极反应式为：2Cu＋2OH^－－2e^－=Cu₂O＋H₂O

D．在水泥固化过程中，由于自由水分子的减少，溶液中各离子浓度的变化导致电动势变化
