Which experiment could prove that the decerebrate rigidity is γ rigidity.

A、the rigidity disappears after transecting the afferent fiber of muscle spindle.

B、stimulation of the facilited area in reticular formaiton in barin stem enhances the rigidity.

C、the rigidity disappears after transectiong the spinal cord

D、the rigidity disappears after transecting the spinal efferent nerve

E、stimulation of γ motor neuron enhance the rigidity.

Which one is more coherent?

A、The most striking example of value rigidity I can think of is the old south Indian Monkey Trap, which depends on value rigidity for its effectiveness.A hollowed-out coconut chained to a stake makes the trap. A monkey can put its hand though a small hole in the coconut and grab some rice inside. The monkey can put its hand into the hole but cannot take its fist out with rice in it. The monkey's value rigidity traps it when it reaches in. The rice cannot be revalued. He cannot see that freedom without rice is more valuable than capture with it.

The trap consists of a hollowed-out coconut chained to a stake. The coconut has some rice inside which can be grabbed through a small hole. The hole is big enough so that the monkey's hand can go in, but too small for his fist with rice in it to come out. The monkey reaches in and is suddenly trapped - by nothing more than his own value rigidity. He can't revalue the rice. He cannot see that freedom without rice is more valuable than capture with it.

Clonaid, a company associated by a group that believes extraterrestrials created mankind, announced Friday that it had produced the first clone of a human being. According to the spokeswoman, it is a baby girl who appears to have been born healthy.

(47) As we know, cattle, mice, sheep and other animals have been cloned in the past years with mixing success. (48) All cloned animals have displayed defects later in life. (49) Scientists fear same could happen with cloned humans. (50) The company Clonaid is viewed skeptical by most scientists, who doubt the group's technical ability to clone a human being. (51) But the Clonaid spokeswoman said an dependent expert will confirm the baby's clone status through DNA testing.

(52) Clonaid is lead by Brigitte Boisselier a former deputy director of research at the Air Liquide Group, a French producer of industrial and medical gases. (53) Clonaid is also linked to a sect called the Raelians whose founder, Claude Vorihon, describes himself for a prophet and calls himself Rael. (54) The group believes cloning could extend human life for hundred of years. In fact, Clonaid has been racing the Italian fertility doctor Severion Antinori to produce the first cloned baby. (55) Antinori said in last month he expected one of his patients to give birth to a cloned baby in January.

Are you worried about the rising crime rate? If yon

are, then you probably know that your house,

possessions and persons are increasingly in danger of

suffering from the tremendous rise in the cases of burglar 【S1】______

and assault. Figures indicate that it is an ever-increasing 【S2】______

crime rate but it is only too easy to imagine "it will

never happen to me". Unfortunately, statistics show it is 【S3】______

really can happen to you and, if you live in the large

city, you run twice the risk of being a victim. 【S4】______

Fortunately, there is something definite what you 【S5】______

can do. Protect Alarms can help to protect your house

with a burglar alarm system which is effective, simple to

operate and easily affordable. You may remember that 【S6】______

possessing a burglar alarm is no indication which your 【S7】______

house is packed with valuable possessions. It quite

simply indicates of unwelcome visitors that yours is one 【S8】______

house they will not break into easily so they carry on to

an unprotect house where their job is made a lot easier. 【S9】______
