Construction workers in Southern California have made a wild discovery. They were digging at a building site in San Timoteo Canyon (峡谷) when they unearthed hundreds of ancient animal fossils. Researchers say the bones hold important clues about the history of the region.
Nearly 1, 500 fossils were recovered from the dusty canyon. The remains are about 1.4 million years old. They include the bones of a new species of deer, several small rodents (啮齿目动物) and more. A giant cat fossil was also found. Scientists believe the animal was an ancestor of the saber- toothed tiger. Signs of plant life were uncovered as well.
“This is a huge find,” says Rick Greenwood, a scientist studying the site. “I don’t think most people had any idea that those types of animals were wandering around here more than a million years ago.”
San Timoteo Canyon is located about 85 miles from Los Angeles. The area of the canyon where the fossils were found was once part of a green river valley. Today, the region is dry and plant life is rare.
Most of the fossils are well preserved. Experts say a muddy lake bed may have trapped thirty animals that wandered over for a drink. The mud helped to protect the animal fossils.
The remains are a million years older than those discovered at the famous La Brea Tar Pits in Los Angeles. Scientists studying the bones will be able to learn more about how the animals adapted to changes in the environment.
“We have a confused view of what this time period was like, ” says another scientist. “A discovery like this could really be an important contribution.”
About 35 different animal species are represented in the fossil collection. Scientists began removing bones from the site last fall. The project was completed this summer. Starting next year, the fossils will be on display at the Western Science Center in the nearby city of Hemet, California.

It is true that shyness can be a disadvantage socially for those who suffer from it seriously. I mean real shyness, not somebody who is simply quiet. Quiet people could be shy, but on the other hand, they may just be observing because they are unsure of you or others in your company. They may be capable of being extrovert (性格外向的) and sociable, but on some particular occasions, they are quiet.
I have learnt from my experience that those who observe and listen more and talk less can gain a position of strength. This means that even a very shy person, the type who is reluctant to talk in company (在交际场合) , especially new company, can become a strong person in just about anything they choose. Remember, knowledge is power, and a shy introvert (性格内向的人) is in a better position to gain knowledge than an extrovert. Introverted people can give great attention to learning, and as good listeners they can take in an enormous amount from others. Over time, people can come to respect them far more than the extrovert who speaks a lot. Usually about themselves.
What does it take , then for a very shy person to be that successful person they have always wanted to be ? They may only need one more thing to push themselves on their way. They need to dare themselves to take the leap; and when they do , they will probably find all the knowledge they have gained over the years will help them on their way to the top in their chosen field.

What does the first paragraph mainly want to tell us?

A．A person who is quiet may not be shy.

B．A shy person may not be a calm one.

C．Quiet people are usually doubtful.

D．Shyness is sometimes a bad feature.

Count Me Out
Call me old-fashioned. Call me old. Call me what you want, but I refuse to become part of this new Internet world.
I do not possess a computer at home or at the office. Actually, I stopped going to an office 35 years ago, when all communications were done with a pen, a typewriter, or, if the matter was of world-shaking importance, over the telephone. Likewise, if you like something advertised in a newspaper or magazine, you visited the shop selling it at the given address, or you phoned the number shown. Then you spoke to the fellow and asked for further details.
Tell me what you think of the following ad that appeared the other day in the newspaper. It was for a cure for cancer and this is what it said: “Awareness is the key. Visit spfulford. com at the awareness site.” There was no address or telephone number for the site. So what do unfortunate people without a computer do if they are seeking a cure for their illness?
There are, I am told, certain advantages in having access to the Internet. You can, for example, send love messages across the world or even get married to someone that you meet online. This bit doesn’t interest me; I have been happily married for 60 years. There are, of course, other activities for Internet users besides finding love. They can pay bills, order groceries, or discuss with their doctors.
And this is by no means all. More amazing things are yet to come in the near future. I read a newspaper report recently that quoted Stephen Hawking, an important British scientist. “The complexity of a computer as it exists today is probably less than the brain of an earthworm,” he said. “But, as technology advances, computers will become more complex, and a time may come when the Internet may develop ‘consciousness.’ In other words, the Internet will be able to think, have feelings, and may well be able to act on its own.”
If Professor Hawking is right, I may change my attitude to computers. As I grow older each day, I would like one of those that not only thinks for me but also accepts responsibilities for all my mistakes.

When other nine-year-old kids were playing games, she was working at a petrol station. When other teens were studying or going out, she struggled to find a place to sleep on the street. But she overcame these terrible setbacks to win a highly competitive scholarship and gain entry to Harvard University. And her amazing story has inspired a movie, “Homeless to Harvard：The Liz Murray Story” , shown in late April.
Liz Murray , a 22-- year-- old American girl, has been writing a real--life story of willpower and determination. Liz grew up in the shadow of two drug--addicted parents. There was never enough food or warm clothes in the house. Liz was the only member of the family who had a job. Her mother had AIDS and died when Liz was just 15 years old. The effect of that loss became a turning point in her life. Connecting the environment in which she had grown up with how her mother had died, she decided to do something about it.
Liz went back to school. She threw herself into her studies, never telling her teachers that she was homeless. At night, she lived on the streets. “What drove me to live on had something to do with understanding, My understanding was that there was a whole other way of being. I had only experienced a small part of society,” she wrote in her book Breaking Night.
She admitted that she used envy to drive herself on. She used the benefits that come easily to others, such as a safe living environment, to encourage herself that "next to nothing could hold me down". She finished high school in just two years and won a full scholarship to study at Harvard University. But Liz decided to leave her top university a couple of months earlier this year in order to take care of her father, who has also developed AIDS. "I love my parents so much. They are drug addicts. But I never forget that they love me all the time."
　　Liz wants moviegoers to come away with the idea that changing your life is "as simple as making a decision".

Motorists who used to listen to the radio or their favorite tunes on CDs may have a new way to entertain themselves, after engineers in Japan developed a musical road surface.
A team from the Hokkaido Industrial Research Institute has built a number of“melody roads,”which use cars as tuning forks to play music as they travel.
The concept works by using grooves(凹槽).They are cut at very specific intervals in the road surface. The melody road uses the spaces between to create different notes.
Depending on how far apart the grooves are, a car moving over them will produce a series of high or low notes, and designers are able to create a distinct tune.
Paten documents for the design describe it as notches “formed in a road surface so as to play a melody without producing simple sound or rhythm and reproduce melody-like tones”.
There are three musical strips in central and northern Japan—one of which plays the tune of a Japanese pop song. Reports say the system was invented by Shizuo Shinoda. He scraped some markings into a road with a bulldozer before driving over them and found that they helped to produce all kinds of tones.
The optimal speed for melody road is 44kph,but people say it is not always easy to get the intended sound.
“You need to keep the car windows closed to hear well,”wrote one Japanese blogger.“Driving too fast will sound like playing fast forward, while driving around 12mph［20km/h］has a slow-motion effect, making you almost car-sick.”
