     Honesty is the best policy, as the English saying goes. Unfortunately, honesty often leaves us when no

one is watching, British psychologists reported last week.

Researchers at UK's Newcastle University set up an experiment in their psychology department's coffee

room.

     They set a kettle, with tea, coffee and milk on the counter and hung up a sign listing the price for drinks. People helping themselves to a cup of tea were supposed to put a few cents in the box nearby.

     The scientists hung a poster above the money box, and changed each week between pictures of

gazing (注视的) eyes and pictures of flowers. The researchers found that staff paid 2.76 times more for

their drinks when the image of the eyes was hung.

     "We were shocked by the size of the effect," said Gilbert Roberts, one of the researchers.

     Eyes are known to be a powerful perceptual (知觉的) signal for humans, scientists say.

     "Even though the eyes were not real, they still seemed to make people behave more honestly," said

Melissa Bateson, a behavioral biologist and leader of the study.

     Researchers believe the effect throws light on our evolutionary(进化的) past. It may arise from

behavioral characteristics that developed when early humans formed social groups to increase their

chances of survival. For social groups to work, individuals had to co-operate, rather than act selfishly.

"There's an argument that if nobody is watching us, it is in our interests to behave selfishly. But when

we're being watched we should behave better. So people see us as co-operative and behave the same

way towards us," Bateson said.

     The new finding indicates that people have a striking response to eyes. That might be because eyes

and faces send a strong biological signal we have evolved to respond to, Bateson said.

     The finding could be put to practical use. For example, images of eyes could ensure ticket sales on

public transport and improve surveillance(监视) systems to deter antisocial (反社会) behaviour.

A. warn you to behave honestly whether you are alone or not

2. The experiment carried out in Newcastle University made researchers think that _______.

A. honesty is not the best policy

B. evolution has a big influence on our behavior

C. humans have to form social groups to survive

D. people are more relaxed when not being watched

问答题

A市的电器公司和该市的百货公司签订一份供货合同,电器公司每个季度向百货公司供应彩电500台,百货公司在年底付款。为了保证电器公司的利益,百货公司提供了一家五金公司作保证人,电器公司和五金公司签订了一份一般担保协议。双方约定,五金公司在总合同金额范围内承担一般的保证责任。在年底的时候,百货公司没有能够按时支付电器公司的价款。电器公司提起诉讼。
问:(1)此时电器公司可以如何选择被告法院又应当如何处理如何确定管辖法院
(2)如果作为保证人的不是五金公司而是经过五金公司授权的分支机构,此时保证合同是否有效此时,原告可以如何选择被告为什么
(3)如果电器公司和五金公司签订的合同是连带保证合同,电器公司在提起诉讼时,可以如何选择被告
(4)假设电器公司和五金公司签订的不是保证合同而是抵押担保合同,在电器公司未获得价款后,电器公司要求行使抵押权,因为无法和五金公司就抵押物的处分达成协议,发生争议,电器公司此时提起诉讼,应当如何选择被告如果合同同时约定五金公司承担连带保证责任,则电器公司应当向哪个法院提起诉讼
(5)电器公司在对百货公司提起诉讼后,获得胜诉,但是,在强制执行时发现百货公司的财产根本不足清偿法院判决的金额,此时能否根据保证合同直接执行五金公司的财产如果能,为什么如果不能电器公司应当怎样保护自己的合法权益
