It took courage to stand up at work. Now more and more people like to have a change and stand up when they are on something important. Standing up is popular. Medical researchers have found that people who stand at work tend to be much healthier than those who sit.
In the last few years, many office supply companies have begun to sell the adjustable- height desk. These so- called “ sit/ stand” models are equipped with an electric motor that lets them shift from chair height to person height at the push of a button. Unfortunately, they’re regarded as specially furniture. Sit/ stand desks tend to be expensive, hard to find and not easy to test it in person.
When you worked standing up, your mind was more excited and new ideas kept coming out. This is because when you’re standing, you feel a bit unchained from your desk. If you got stuck on a word or sentence as you wrote, you found yourself shaking your arms, bouncing on your feet or stepping away from the desk for a bit------ things you couldn’t do in a chair. Often, standing up seemed to relax your mind enough for you to get over creative barriers.
There’s one other thing about standing for a long time; you tended to get hungrier than you do when you sit on a chair. That felt like confirmation of the stand-up advocates’ belief that you burn more calories when you stand than when you sit. For this reason alone, I’m hoping that sit/ stand desks one day hit the mainstream, with mass- market furniture companies making many low- priced versions. We could all do with a bit more standing up.
1.We can learn that the adjustable- height desk is_______.
|
A．easy to find |
B．easy to test |
|
C．relatively cheap |
D．smart in operation |
2.According to para.3, standing up while working ______.

|

|

Angela Chang(张韶涵) didn’t know it would be so hard to turn singing into a career. She went to many different record companies. But she was always turned down for looking too young and small.
“I’d never had such difficulties before,” Chang said. But Chang’s talent was finally accepted in 2002. When she got a piece of work, she cried.
She soon became a star. Her first album Over the Rainbow sold very well. She won many awards.

But the 25-year-old girl has other talents too. Chang is also an actress. She has played a role in the popular TV plays, My MVP Valentine and At Dolphin Bay. Many people remember her common-girl parts in the plays. But acting is difficult. Chang once acted so badly that she was nearly fired. Another time it took her 27 tries to get a scene right.
“I cried when I got back home,” Chang said. “But I knew that I wouldn’t always fail. You only fail when you give up.”
Now with four albums behind her - Over the Rainbow, Aurora, Pandora and Flower in the Wonderland, it’s clear that Chang and music were made for each other. As she sings in one song, “I have a pair of invisible wings. They fly me to the sky and give me hope.”

The high noise of modern life may affect speech and language development in the very young, according to a study that found the auditory (听觉的) parts of the brains of young mice are slower to organize properly in the presence of continuous sounds.
Researchers at the University of California, San Francisco, reared a group of rats in an environment of continuous background noise and found that their brain circuits that receive and interpret (解释) sound did not develop at the same rate as animals that were raised in a quieter environment.?
Edward F. Chang and Michael Merzenich, co-authors of the study appearing in the journal Science, said that the continuous noise delayed the organization of auditory neurons (神经细胞) during a critical two-to-three-week period after the rat pups were born.?
For rats not exposed to the noise, the auditory cortex(皮层) neurons during this period gathered into a smaller area and began developing a selective response to sounds.?
But for the noise?exposed rats, this organization was slowed, causing a delay in the development of the ability to discriminate(辨别) specific sound tones. The researchers said it took three or four times longer for the rats raised in a noisy environment to reach the basic bench marks (基准) of auditory development seen in the rat pups not exposed to noises.?
Although the rat is not a perfect model for what happens in humans, the authors note, the study does suggest that high levels of noise might possibly affect some language learning in babies.?
“These findings suggest that environmental noise, which is commonly present in contemporary child-rearing environments, can potentially contribute to auditory and language-related development delays,”the authors wrote in Science.?
The authors noted that although the brain development was delayed in rats exposed to the noise, their brains did eventually mature (成熟的) normally.?
The scientists at California University studied rats_______.?
A. of different age groups B. with different habits?
C. in different environments D. from different areas?
The rats exposed to noise, compared to those not exposed, _______.?
A. were more sensitive B. were duller?
C. grew up more slowly D. gathered together more quickly
The result of the research mainly tells us that noise _______.
A. delays brain development B. stops baby growth
C. affects speech and language D. destroys brains?
The findings of the research are said to have special connections with _______.
A. causes of noises B. medical science?
C. other living things D. human babies??

阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。
Ａ
Researchers who helped discover a new species of Mexican butterfly are offering to sell the naming rights to raise money to fund more research. Co-discoverer Andrew Warren is hoping to raise at least $50,000 by auctioning(拍卖) off the rights to name the 4-inch “owl eye” butterfly, which lives in Sonora, a Mexican state bordering Arizona.
“That would support at least two years of research for our team down in Mexico,” Warren said. “Money goes a long way down here in Mexico.”
According to the scientific tradition, discoverers of a new species have the say in naming it. In recent years, some discoverers have auctioned off their naming rights to raise money.
Warren said the amount being sought for the butterfly is not out of the question, noting that naming rights for a new monkey species brought in $650,000 two years ago. A group of 10 new fish species that went on the naming auction block at the same time earlier this year brought in a total of $2 million.
The butterfly discovered by Warren and researcher George Austin ranges as far north as Mexico.
The butterfly was actually in a collection, misidentified as an example of another new species, at the McGuire Center for Lepidoptera and Biodiversity at the Florida Museum of National History in Gainesville, said Warren. They soon began the hard process of determining that it was indeed a “new” model of butterfly.
After checking photos and comparing it with other known species, they determined it was a separate species.
【小题1】Where did the researchers discover the new species of butterflies?
| A．In Sonora. | B．In Mexico state. |
| C．In a place in US. | D．Near the US-Mexico border. |
| A．To raise money for wildlife protection. |
| B．To raise money for more research. |
| C．To cause people’s attention to the new discovery. |
| D．To cover the cost of the research. |
| A．it was a new species at once |
| B．it wasn’t a species of American butterfly |
| C．it belonged to the monarch branches |
| D．it belonged to a new species |
| A．the new species of butterfly live both in the US and Mexico |
| B．it took the researchers a lot of efforts to determine the new species of butterfly |
| C．the researchers are not sure whether they can get the money they want from the auction |
| D．it is the first time that the new species of butterfly has been found |
