But something is happening to the children. Up until the age of two they develop normally. Their proud parents watch and smile as they take their first steps and speak their first words. But then everything seems to go backwards. The children become locked into their own small world, unable to communicate at all.
They call it the “curse of Silicon Valley,” but the medical name for the condition is autism（孤独症）. It used to be thought that autism was a mental illness. Now doctors are sure that it is a disease transmitted genetically (遗传). It seems that the people leading the communications revolution are having children who cannot communicate at all.
But even the parents have trouble communicating. Asperger’s Syndrome (综合症) is connected with autism. People who have it are highly intelligent and often brilliant with numbers or systems but have no social skills, which makes Asperger’s sufferers into excellent computer professionals. Unfortunately, many of the children of two Asperger’s parents in Silicon Valley seem to be developing serious autism.
There is little anyone can do. And there is no cure in sight. Some argue that no cure should be found．“It may be that autistics are essentially (本质上) different from normal people, but that these differences make them valuable for the evolution (进化) of the human race,” says Dr Kirk Wilhelm of the University of California．“To remove the genes (基因) for autism could be terrible.
It seems that the children of Silicon Valley are paying the price of genius.

When you first learned to read, you would say the word out loud and sound it out．Then you might whisper the word because people can become annoyed when you read aloud．The stage you are now at is saying the word in your head．Most people tend to read this way．Saying the word in your head will cut your reading speed tremendously (极大的)．
How do you calculate your reading speed? The speed is measured by how many words per minute you can read．Get some reading material, preferably a book．Find out how many words are on the page．Time yourself one minute．Start your timer and start reading．When the timer sounds, stop at once．If you counted 500 words on the page and you read half of the page, then you are probably reading at 250 words per minute．
The first thing about speed-reading is looking at the word and recognizing it．Don"t say the word in your mind, just look at it and recognize its appearance．Later you will recognize groups of four words or more to increase your speed．This is the first and most important step in speed-reading．
The next step is technique．As with any other skill, speed-reading requires technique．You should first be sitting up straight with your book on a horizontal (水平的) surface, such as a table or desk．Next, should be able to see the entire page．This is necessary if you want to recognize clumps of words．Lastly, you should be focused．It"s hard to read a lot of noise．Find a quiet place to read．This will help your understand of the text．You need something to guide your eyes while reading．Then right, you should use your hand, Remember when you were little, you would read using your finger．That is a great technique, only now you"re using your hand to underline each line．Move your finger smoothly across page．No need to go rush , start our slow．Keep your eyes focused on words as you recognize them while using your hand as a guide．This will increase you speed．
The third step is practice．Practice makes perfect．Set time intervals(间歇)．Read using different techniques, but make sure you understand what you"re reading．
小题1:Which of the following statements is true according to the text?
| A．Now there is limited information than ever before． |
| B．Now conditions ask people to use less time to know more information． |
| C．Now people can read what they like． |
| D．The less you read, the more time you will spend． |
| A．What speed-reading is． |
| B．Why we need speed-reading． |
| C．Now it is much information time． |
| D．People should practice speed-reading in different kinds of ways． |
a．Ask for some techniques．
b．Look at many words and recognize them．
c．Practice more．
| A．c,a,b | B．c,b,a | C．b,a,c | D．a,c,b |
| A．a person should devote his attention to it while reading |
| B．your feelings will be hurt while reading |
| C．a person should smooth away difficulties while he reads |
| D．you should pay attention to your faults while you are reading |

Getting away for a short time always seems like a great idea — until you have to pack. But packing won’t be a problem if you keep in mind one simple rule. Whether you’ll be sleeping overnight at a friend’s house, or visiting a relative for a week, the rule is: pack light. Here are some tips to help you pack.
Many years ago my student asked me the question, "Mrs. Kindred, why do you teach?" Without taking time to reflect, I answered, "Because someday I might say something that might make a difference in someone"s life." Even though I was sincere, that wasn"t a very good answer and my student didn"t let it slide.
"Let me get this straight," he said, "You went to college for four years so you could come here every day because you have the hope that someday you might say something that will influence someone?" He shook his head as if I were crazy and walked away looking confused. I"m one of those people who look back and wish they had said something smart or witty, or swift.
Even though that particular student might no longer wonder why I teach, there are days when I wonder. On those days, I remind myself of the real reasons I teach:
It"s in my blood. My mother was my most influential teacher, and she was a 6th grade reading teacher until her death in 1990. She instilled(逐渐灌输) in me a love of reading and the knowledge that education opens doors.
Teaching is a way to make a difference. If you throw a stone in a pond the ripples go on and on until they reach the shore. You can"t have ripples without a "stone." Good teachers throw stones that make a positive difference, and that"s what I strive to do.
I genuinely love teenagers. I want to share with others what I know and what I have learned through the years. Life is full of ups and downs, and if I can help students avoid some potholes on the road of life, I want to do so. If they"ll allow me to celebrate their victories with them, I want to do too.
Teaching isn"t for everyone, but I know I made the right career choice.
小题1:Why did the student continue to ask the question about the writer’s being a teacher?
| A．Because he thought her answer was unbelievable. |
| B．Because the writer was insincere. |
| C．Because the student was naughty. |
| D．Because the answer was difficult to understand. |
| A．Stupid. | B．Honest. | C．Conservative. | D．Polite. |
| A．The writer’s mother has the greatest influence on her. |
| B．The writer’s answer made the student confused. |
| C．In the writer’s opinion, some people in the world are unfit to teach. |
| D．The writer annoyed the student who asked the question. |
| A．the writer was also a good teacher in school |
| B．the writer often plays with her students beside a pond |
| C．the writer devotes herself to teaching and her students |
| D．the writer often accompanies the students on their way home |
| A．A student’s silly question. | B．A good teacher who likes students. |
| C．A confused student. | D．The reason why I teach. |
GUATEMALA CITY （Reuters） – A fish that lives in mangrove swamps(红树沼泽) across the Americas can live out of water for months at a time, similar to how animals adapted(适应) to land millions of years ago, a new study shows.
The Magrove Rivulus, a type of small killifish, lives in small pools of water in a certain type of empty nut or even old beer cans in the mangrove swamps of Belize, the United States and Brazil. When their living place dries up, they live on the land in logs(圆木), said Scott Taylor, a researcher at the Brevard Endangered Lands Program in Florida.
The fish, whose scientific name
is Rivulus marmoratus, can grow as large as three inches. They group together in logs and breathe air through their skin until they can find water again.The new scientific discovery came after a trip to Belize.
“We kicked over a log and the fish just came crowding out,” Taylor told Reuters in neighboring Guatgemala by telephone. He said he will make his study on the fish known to the public in an American magazine early next year.
In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at time, while lungfish found in Australia, Africa and South America can live out of water, but only in an inactive state. But no other known fish can be out of water as long as the Mangrove Rivulus and remain active, according to Patricia Wright, a biologist at Canada’s University of Guelph.
Further studies of the fish may tell how animals changed over time.
“These animals live in conditions similar to those that existed millions of years ago, when animals began making the transition(过渡) from water onto land,” Wright said.
1. The Mangrove Rivulus is a type of fish that _______.
A. likes eating nuts
B. prefers living in dry places
C. is the longest living fish on earth
D. can stay alive for two months out of water
2. Who will write up a report on Mangrove Rivulus?
A. Patricia Wright.
B. Scott Taylor.
C. Scientists from Belize.
D. Researchers in Guatemala.
3. According to the text, lungfish can ________.
A. breathe through its skin
B. move freely on dry land
C. remain alive out of water
D. be as active on land as in water
4. What can we say about the discovery of Mangrove Rivulus?
A. It was made quite by accident.
B. It was helped by Patricia Wright.
C. It was based on a lab test of sea life.
D. It was supported by an American magazine.
Scientists first predicted in the 1970s that heat trapped in the Earth’s atmosphere could cause a polar meltdown. Many now believe that human activities are turning up the heat. When we burn fossil fuels like coal and oil, we add carbon dioxide(CO2) gas to the Earth’s atmosphere. Cutting down trees also makes CO2 levels raise because trees normally soak up CO2 to make food. Scientists say higher CO2 levels strengthen the “greenhouse effect” and could increase the Earth’s temperature. In fact, CO2 levels have risen by 30 percent since the Industrial Revolution of the 18th and 19th centuries.
Over the past three years, satellite measurements have shown a sea level rise of about a quarter inch worldwide. “If nothing is done to reduce fossil-fuel pollution and global warming, sea levels will rise even more.” says geologist Richard Alley.
But even Alley admits that a polar meltdown would take time. The ice in Antarctica and Arctic locks up nearly nine times the volume of water contained in all the world’s rivers and lakes. These are such big “ice cubes” and it would probably take thousands of years to melt them.
Another scientist Charles Bentley doesn’t think a meltdown will happen at all. “Even if warmer temperatures begin to melt polar-ice,” he says, “the excess moisture would most likely be redeposit as snow.” In other words, the melted ice would evaporate into the atmosphere, refreeze, and fall as rain and snow over the Poles.
小题1:What consequence of global warming is mentioned in the passage?
| A．More tropical storms. | B．More tropical diseases. |
| C．Changes in farm productivity. | D．Coastal flooding. |
| A．CO2 in the atmosphere cannot keep the heat from escaping into space. |
| B．The increase of CO2 gas may warm the planet and help to melt polar ice. |
| C．Cutting down trees helps to greatly reduce CO2 levels. |
| D．The end of the short-lived age of fossil fuels is already in sight. |
| A．the sea-level rise can be prevented by cutting back on energy-consuming activities |
| B．the recent breaking off of ice blocks from Antarctica is just a natural part of a long-term cycle |
| C．Antarctica temperatures have significantly changed since the Industrial Revolution |
| D．the polar meltdown may be an accidental change of climate rather than a sign of global warming |
| A．governments around the world are beginning to reduce CO2 levels in the air |
| B．a melting of the polar ice cannot be achieved with the present technologies |
| C．the melted ice in the polar areas would change into snow and rain over the Poles |
| D．the sun’s heat would have no chance of being absorbed by the polar ice |
| A．In the second paragraph. | B．In the third paragraph. |
| C．In the fourth paragraph. | D．In the fifth paragraph. |
