It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He ma
de the monkeys’ blood back to the monkeys’ brains. When the brain’s temperature was 10℃, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them. The biggest difficulty in operating on the damaged brain is that .
| A．the time is too short for doctors | B．the patients are often too nervous |
| C．the damage is extremely hard to fix | D．the blood-cooling machine might break down |
The brain operation was made possible mainly by .
| A．taking the blood out of the brain | B．trying the operation on monkeys first |
| C．having the blood go through a machine | D．lowering the brain’s temperature |
With Dr. White’s new idea, the operation on the damaged brain .
A．can last as long as 30  minutes |
B．can keep the brain’s blood warm |
| C．can keep the patient’s brain healthy | D．can help monkeys do different jobs |
What is the right order of the steps in the operations?
a. send the cooled back to the brain b. stop the blood to the brain
c. have the blood cooled down d. operate on the brain
| A．a, b, c, d | B．c, a, b, d | C．c, b, d, a | D．b, c, d, a |
Which of the following is not true?
| A．If there isn’t enough blood, the brain can live for only three to five minutes. |
| B．If the brain is very cold, it can live without blood for half an hour. |
| C．Dr. White tried his idea for thirteen times. |
| D．After their operations, the monkeys were healthy and busy again. |
Windsurfing is a sport that combines sailing and surfing．In 1948，twenty-year-old Newman Darby first 
thought of using a handheld sail to contro1 a small boat．Darby did not apply for a patent(专利)for his design at first．However，he is recognized as the inventor of the first sailboard．
Californians Jim Drake，a sailor and engineer，and Hoyle Schweitzer，a surfer and skier received the patent for a sailboard．They called their design a windsurfer．The early windsurfer boards measured 3．5 meters long and weighed 60 pounds．Later in the l980s，Newman Darby did apply for and receive a design patent for a one—person sailboat．
In the late l940s，Newman Darby found he could control a 3-meter-long sailboat and make turns even without a rudder(舵)．In l964 he designed the first universal joint(万向接头)to go along with a flat bottom sailing boat．This sailboard was equipped with a universal joint，a board and a kite—shaped free sail and thus windsurfing was born．
Naomi Darby，Newman’s wife，was the first woman windsurfer and helped her husband build and design the first sailboard．She sailed while standing up，controlling the boat without the use of a rudder．She tilted(倾斜)the sail to change directions．This was something that had never been done before．
Hoyle Schweitzer began producing sailboards in the early 1970s．The sport became very popular in Europe．By the late 1970s，windsurfing fever had Europe firmly in its grasp with one in every three families having a sailboard．
The first windsurfing world championship was held in 1973．Windsurfing first became an Olympic sport for men in l984 and for women in l992．Jim Drake and Hoyle Schweitzer received the patent for the design of．

Buster Brown was a thief-and a good one，too，he thought . He’d never been caught by the police because he never took chances． He was always prepared for any unforeseen event or emergency.
Confidently，he stood outside the house of his intended victim(受害者)and read the sign on the front gate of the house．“Don't worry about the dog—be aware of the owner!”it said．Buster smiled and found his way in．
The house looked quite normal outside，but inside it was very exotic with fascinating objects on display．As he began putting them into his bag，a dog came into the room．It stopped when it saw Buster，then wagged its tail madly and went over to him，licking his outstretched hand．
"Good boy，”Buster whispered． “What a great guard dog you are—trying to lick me to death.”
Satisfied he'd made friends with the dog，Bluster began to wander round the house，choosing items to put in his bag．His
skilled eye picked out only the best antiques(古董)：a pair of silver candleholders，a silver tea-and-coffee service，etc．．His new friend，the dog，sat and watched，as if wondering what was happening．

"You're a very silly person," the figure(身影) in the doorway said. As the man came closer, Buster could see he was well dressed. His face seemed familiar, but Buster couldn't quite be sure of the place where he had seen him before.
"You should have taken more notice of the sign outside," the man rasped. "I knew about this attempted robbery last week and I also know you will end up behind bars for 20 years. Fancy trying to rob the house of the world's greatest fortune-teller(算命先生)!" Why was Buster so confident?

First the ground shook in Haiti, then Chile and Turkey. The earthquakes keep coming har
d and fast this year, causing people to wonder if something evil (邪恶的) is happening underfoot. It’s not.
While it may seem as if there 
are more earthquakes occurring, there really aren’t. The problem is what’s happening above ground, not underground, experts say. More people are moving into big cities that happen to be built in quake zones, and they’re rapidly putt
ing up buildings that can’t withstand (经受) earthquakes, scientists believe. And around-the-clock news coverage (报道) and better earthquake monitoring(监测) make it seem as if earthquakes are ever-present.
“I can definitely tell you that the world is not coming to an end,” said Bob Holdsworth, an expert in tectonics (筑造学) at Durharn University in the UK.
A 7.0 magnitude quake in January killed more than 230,000 people in Haiti. Last month, an 8.8 magnitude quake--- the fifth-strongest since 1900—killed more than 900 people in Chile. And two weeks ago, a 6.0 magnitude quake struck rural eastern Turkey, killing at least 57 people.
On average, there are 134 earthquakes a year that have a magnitude between 6.0 and 6.9, according to the US Geological Survey. This year is off to a fast start with 40 so far—more than in most years for that time period.
But that’s because the 8.8 quake in Chile generated a large number of strong aftershocks, and so many quakes early this year skews (扭曲) the picture, said Paul Earle, a US seismologist (地震学家).
Also, it’s not the number of quakes, but their devastating impacts(破坏性的影响) that gain attention, with the death tolls (死亡人数) largely due to construction standards (building standard) and crowding, Earle added. “The standard mantra (咒语) is earthquakes don’t kill people, buildings do, ” he said.
There have been more deaths over the past decades from earthquakes, said University of Colorado geologist Roger Bilham. In an opinion colum
n last month in the journal Nature, Bilham called for better construction standards in the world’s big cities.
Of the 130 cities worldwide with populations of more than 1 million, more than half are prone (倾向于) to earthquakes, Bilham said.
Developing nations, where populations are growing, don’t pay attention to earthquake preparedness, Bilham said.” If you have a problem feeding yourself, you’re not really going to worry about earthquakes.”
Another reason quakes seem worse is that we’re paying attention more. The Haiti earthquake quickly followed by the 8.8 in Chile made everyone start to think.
But it won’t last, said US disaster researcher Deniis Mileti. “People are paying attention to the violent planet we’ve always lived on,” Mileti said.” Come back in another six months if there has been no earthquakes, m
ost people will have forgotten it again. ”What is the main idea of the article?
