因承运人责任到使旅客退票时，应如何处理？

为研究高等动物的神经调节，科学家进行相关实验。请回答下列有关问题：

(1)在蛙的坐骨神经表面放置两个电极，连接到一个电表上(电表指针偏转方向代表电流方向)。静息时，电表没有测出电位差(如下图中①所示)。若在图①所示神经右侧的相应位置给予一适当的刺激，则电流表指针偏转的顺序依次为B→____。

依据所观测到的电流表指针偏转情况，绘制出的电流变化情况曲线是下图中的______。

该实验表明：在一个神经元内，兴奋是以____的形式沿着神经纤维传导的。

(2)某反射弧结构完整，效应器为骨骼肌。科研人员用电极分别刺激传入神经和骨骼肌，同时用电流表分别记录传出神经的电流变化情况，则两次电流表的偏转情况依次为____、____。

(3)某研究人员通过实验分离获得两个蛙的心脏：第一个蛙心带有完整神经，第二个蛙心通过手术剔除全部神经。将两个蛙心都装上蛙心插管，并充以少量“任氏液”。持续刺激第一个蛙心脏的神经几分钟，发现心跳加速；随即将其中的任氏液吸出并转移到第二个未被刺激的蛙心脏内，发现后者的跳动也加速了。实验中的“任氏液”相当于蛙体内的____(填成分名称)，以维持蛙心正常的生理功能。根据该实验，可以作出的推断为_______。

                                                                How Much to Tip

     You're out to dinner. The food is delicious and the service is fine. You decide to leave a big fat tip. Why?

The answer may not be as simple as you think.

     Tipping, psychologists have found,is not just about service. Instead, studies have shown that tipping can

be affected by psychological reactions to a series of different factors from the waiter's choice of words, to

how they carry themselves while taking orders, to the bill's total. Even how much waiters remind customers

of themselves can determine how much change they pocket by the end of the night.

     "Studies before have shown that mimicry (模仿) brings into positive feelings for the mimicker," wrote

Rick van Baaren, a social psychology professor. "These studies show that people who are being mimicked

become more generous toward the person who mimicks them."

     So Rick van Baaren divided 59 waiters into two groups. He requested that half serve with a phrase such

as, "Coming up!" Those in the other half were instructed to repeat the orders and preferences back to the

customers. Rick van Baaren then compared their take-home pay. The results were clear-it pays to mimic your

customer. The copycat (模仿者) waiters earned almost double the amount of tips to the other group.

     Leonard Green and Joel Myerson, psychologists at Washington University in St. Louis, found the generosity

of a tipper may be limited by his bill. After research on the 1,000 tips left for waiters, cabdrivers, hair stylists,

they found tip percentages in these three areas dropped as customers' bills went up. In fact, tip percentages

appear to plateau (稳定期) when bills topped $100 and a bill for $200 made the worker gain no bigger

percentage tip than a bill for $100.

     "That's also a point of tipping," Green says. "You have to give a little extra to the cabdriver for being there

to pick you up and something to the waiter for being there to serve you. If they weren't there, you'd never get

any service. So part of the idea of a tip is for just being there."
