8.It was about 11:15pm on the passenger ship California.The night was freezing cold and the water was filled with ice from the North Pole,making it difficult for the ship to sail on.
In the radio room,operato Cyril Evans listened to the radio-talk between a nearby passenger ship and the telegraph station on the Canadian island of Newfoundland.Evans interrupted it and said,"We're stopped and surrounded by ice.Be careful as you pass through these waters."The radio operator on the nearby ship replied,"I'm too busy to talk now.I have many messages to send to the telegraph station."Twenty minutes later,as he turned off his radio and went to bed,Evans could still hear the ship sending its passengers'telegrams.
Earlier in the evening the California's captain,Stanley Lord,had seen another ship approaching.It looked about the size of his own,but attempts to contact the ship failed.It lay dark and mysterious about 10miles away.At 12:40am there appeared a sudden flash of light just over the mysztery ship.Captain Lord,thinking the ship might need help,ordered his officers to signal the ship by lamp.There was no reply.Three more rockets then exploded,none appeared to go higher than halfway up the mast of the mystery ship.Then at about 2:00am it turned and slipped into the darkness.
In the light of the sawn there was no mystery ship,but 20miles away was the scene of a great disaster.Unfortunately,the mystery ship had stopped directly in front of the Califoria,preventing people on board from seeing clearly.If this ship had not been there,Captain Lord would have recognized that the rockets were SOS rockets that came not from the mystery ship but from a more distant ship which the California could not see.If Cyril Evans had kept his radio on for just 30minutes more he would have heard SOS signals coming from that distant ship he spoke with the night before.That ship was the Titanic which was sinking fast,leaving 1,500of its passengers dead.It was April 14,1912.

26.From whose point of view is the story told?B
A.People on the Titanic.
B.People on the California.
C.People at telegraph station.
D.People on Newfoundland.
27.Why were the rockets really fired?B
A.To celebrate the journey.
B.To signal for help.
C.To contact the Titanic.
D.To warn other ships.
28.What is the main function of the last paragraph of this passage?A
A.It shows how unlucky the Titanic was.
B.It describes how the Titanic sank.
C.It indicates that the people on the California were careless.
D.It lists how many people died in the disaster.
29.How many ships are mentioned in the passage?C
A.One.  B.Two.  C.Three.  D.Four.
30.From the passage we know thatD.
A.the rockets were fired from the mystery ship
B.Cyril Evans went to bed earlier than usual that night
C.the Titanic started sinking at dawn the next day
D.the Titanic sent out many telegrams that night.
2.Rene Descartes'explanation of pain has long been acknowledged in medicine.He proposed that pain is a purely physical phenomenon-that tissue injury makes specific nerves send a signal to the brain,causing the mind to notice pain.The phenomenon,he said,is like pulling on a rope to ring a bell in the brain.It is hard to overstate how deeply fixed this account has become.In medicine,doctors see pain in Descartes'terms-as a physical process,a sing of tissue injury.
The limitations of this explanation,however,have been apparent for some time,since people with obvious injuries sometimes report feeling no pain at all.Later,researchers proposed that Descartes'model be replaced with what they called the gate control theory of pain.They argued that before pain signals reach the brain,they must first go through a gating mechanism in the spinal cord(脊髓).In some cases,this imaginary gate could simply step gain signals from getting to the brain.
Their most amazing suggestion was that what controlled the gate was not just signals from sensory nerves but also emotions and other"output"from the brain.They were saying that pulling on the rope need not make the bell ring.The bell itself-the mind-could stop it.This theory led to a great deal of research into how such factors as mood,gender,and beliefs influence the experience of pain.In a British study,for example,researchers measured pain threshold and tolerance levels in 53 ballet dancers and 53 university students by using a common measurement:after immersing your hand in body-temperature water for two mintues to establish a baseline condition,you put your hand in a bowl of ice water and start a clock running.You mark the time when it begins to hurt:that is your pain threshold.Then you mark the time when it hurts too much to keep your hand in the water:that is your pain tolerance.The test is always stopped at 120 seconds,to prevent injury.
The results were striking.On average female students reported pain at 16 seconds and pulled their hands out of the ice water at 37 seconds.Female dancers were almost three times as long on both counts.Men in both groups had a higher threshold and tolerance for pain,but the difference between mals dancers and mals nondancers was nearly as large.What explains that difference?Probably it has something to do with the psychology of ballet dancers-a group known for self-discipline,physical fitness,and competitiveness,as well as by a high rate of chronic(慢性)injury.Their driven personalities and competitive culture evidently accustom them to pain.Other studies along these lines have shown that outgoing people have greater pain tolerance and that,with training,one can reduce one's sensitivity to pain.
There is also striking evidence that very simple kinds of mental suggestion can have powerful effects on pain.In one study of 500 patients undergoing dental procedures,those who were given a placebo injection and promised that it would relieve their pain had the least discomfort-not only less than the patients who got a placebo and were told nothing but also less than the patients who got actual drug without any promise that it would work.
Today it is abundantly evident that the brain is actively involved in the experience of pain and is no more bell on a string.Today every medical textbook teaches the gate control theory as fact.There's a problem with it,though.It explains people who have injuries but feel no pain,but it doesn't explain the reverse,which is far more common-the millions of people who experience chronic pain,such as back pain,with no signs of injury whatsoever.So where does the pain come from?The rope and clapper are gone,but the bell is still ringing.

Let me take you(21)A a couple of years.Come with me as we relearn a lesson,one that has stuck with me,in my present memory,and (22)D me yet.
We walked into Elida Road Hardware,an old-fashioned hardware store.No automatic door,not a computer in the building.It was one that I went to fairly often.As we entered the door,two sounds (23)A us.The sleigh bells of last year made that sweet,peaceful tinkle as we opened the door.The other sound was the electronic beeper that reminded Andy of our(24)D.
"Good afternoon,Ryan,"(25)C the cheerful greeting.Andy was a very (26)B sort of owner.He was of medium build and height,and the smile on his face welcomed us.
We walked across the old wood floor.Andy asked us what he could help us with.I told him we were (27)B a spring.He very patiently replied,"I have lots of springs.You're going to need to be more(28)A."
"Just a spring for an old-fashioned screen door."
"That's it.A screen door spring.Right down there."We (29)B  where he was pointing,and sure enough,there they were.Andy knew his store,and his products.That was why I came here instead of Meijer.The service couldn't be beaten.The price-Yes.But service and (30)C
-No.
I picked up one and followed him to the (31)C.
He (32)A the price,doing the math in his head."1.88,withtax:comesto 1.99."
"Put it on my dad's account."
He nodded and smiled,"Good dad's account."He laughed."I don't know what you boys would do (33)B  dad's account!"
He handed me the ticket and as I (34)B  it I asked,"You really trust my signature?"
His reply surprised,(35)A delighted me."When I can't trust Jerry Hoover's boys I can trust nobody!"
We left,and the brain (36)A  started to forget things,in order of importance.But what Andy said that day rang in my ears.And it rings in my ears today.That's a tall order to live up to.It's a high standard of (37)D.My father made a fame for that name,and I get to (38)D the benefits.But on account of this,I must (39)A that fame.And that's (40)C  business.
