Chicken feathers are useful, and not just to a chicken. Some go into pillows, coats and other products. But countless chicken feathers go to waste.
In the United States, billions of chickens are produced yearly. Most of their feathers are thrown away.
But instead of being buried in land, some feathers could find a future in plastics(塑料).
One of the products they have developed is a flowerpot(花盆). It may look like other flowerpots. But the container breaks down in the earth within one to five years. And as it breaks down, it naturally becomes nutrient(营养物) in the soil.
The environmentally friendly flowerpot is the work of two researchers. Walter Schmidt is with the Agricultural Research Service, part of the United States Agriculture Department. Masud Huda is with the Horticultural Research Institute, a private(私人) organization(组织).
Walter Schmidt has been working to find uses for chicken feathers since the 1990s. Progress in 2002 showed that plastic made from feathers could be formed like other plastics.
He says feathers are much stronger and last(持续) longer than another plant material. "Feathers are stronger. By design, feathers are also more durable(耐用的). And the other part about it is if feathers were twice as heavy, or half as strong, then birds couldn't fly."
He points out that traditional flowerpots made from other plastics can last much longer. But he wonders if there is really a need. He says most flowerpots are never re-used.
"Why would you want a plastic that you use for a year to last for two hundred years? It makes no sense. You want to match the product with the use." said Walter Schmidt.
Walter Schmidt and Masud Huda are now adding another chicken product to their flowerpots -- chicken waste. The waste will add more nutrients to the soil as the pot breaks down. The scientists say they hope their flowerpot will be on the market in a year or two.
1.What do people mainly deal with feathers?
A.Feathers are used to make pillows, coats and other products.
B.Most feathers are paid no attention to.
C.Most feathers are used as nutrient
D.Most feathers are used to make flowerpots
2.What’s the advantage of the flowerpots?
A.They won’t last long. B.They can’t break
C.They are environmentally friendly D.They can be reused
3.What does Walter Schmidt think of traditional flowerpots?
A.Too heavy B.Too old
C.Never re-used D.lasting longer but unnecessary
4.What do you think is the main idea of the passage?
A.Chicken and its feathers B.How to deal with feathers

Feathers are not just for flight. They keep birds warm, and attract mates. And for one Australian bird, feathers even help produce an important sound—an alarm.
“People had long noticed these birds produced these loud sounds.” Trevor Murray, a researcher at the Australian National University said. “My supervisor Rob Magrath and May Hingee thought they were used as an alarm. So they did some playbacks and they could show quite strongly that if you play back these sounds to other birds, they flee straightaway. So I was really interested in how they produce the sound, whether it is actually a signal, and whether it’s a reliable signal.”
The team focused their experiment on specific feathers in the pigeon’s wing. “We were able to target the eighth primary feather, which is unusually narrow. And then we also removed, on different sets of birds, those neighboring feathers, the ninth primary feather and the seventh primary feather. And we were able to see when the eighth primary feather was missing, the high note had completely disappeared. So the eighth primary feather produced that high note and the ninth primary feather actually produced the low note.”
And if the birds are fleeing from danger, they produce a louder and higher sound than they do during a normal takeoff. The study is in the journal Current Biology.
Murray and his colleagues did another experiment where they used the recordings they made to observe the reactions of other pigeons. “We were able to see the unusual eighth primary feather was important for signaling the alarm. When that eighth primary feather was missing, they very rarely responded. They almost never fled. Whereas when the ninth primary produces the sound, they fled just as much as to normal alarms. This shows us this unusual primary feather is important for signaling alarm.”
That makes birds of a feather flee together.
1.What does the underlined word “they” in Paragraph 2 refer to?
A. The birds B. Rob and May
C. The feathers D. The loud sounds
2.What did Rob Magrath and May Hingee find out about the birds?
A. They fly away as a group. B. They produce different notes.
C. They send alarms with feathers. D. They attract mates with feathers.
3.Why did the team remove different feathers?
A. To record the notes they produce. B. To keep the pigeons stay in cages
C. To compare their width and length. D. To observe other pigeons’ reactions.
4.According to Murray and his colleagues, why does the unusual feathers matter most?
A. It keeps the pigeons warm B. It responds to alarms
C. It helps birds fly more quickly D. It sounds alarms of danger.

Well, parents, surprise! Lots of us are using Twitter and Facebook to thumb rides, and not just to school. It’s awkward to be refused when you call a friend and ask for a ride. But with Twitter, you just look for other people heading the same way.
It may sound risky, so many teens stay within their own social circles to find rides, and don’t branch out beyond friends when asking on Twitter just like me, but to some young people, especially those taking longer trips, stranger danger is less of a concern.
“I think the digital connection of young people is really key, because younger generations grew up sharing things on line, sharing files, photos, music, etc, so they’ve been very used to sharing,” said Juliet Schor, a sociology professor at Boston College.
The sharing economy got big during the recession (经济衰退), allowing people to access more goods, services using technology and even to share costs. And that technology, for me, is what the car was for my mom, a gateway to more freedom, like what my friend Earl says, “The symbol of freedom isn’t the car any more because there’s technology out there connecting you to a car.”
According to the researchers at the University of Michigan, 30 years ago, eight in ten American 18-year-olds had a driver’s license compared to six in ten today. So it’s not that surprising that on my 16th birthday I wasn’t rushing to get a license but an iPhone.
“Driving, for young people, does mean they have to disconnect from their technology, and that’s a negative. So if they could sit in the passage side and still be connected, that’s going to be a plus.” Schor continued.
To me, another plus is that ridesharing represents something, something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, some of us still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on Twitter.
1.The American teens like the author, prefer to possess an iPhone as a birthday gift because _______.
A. it is most fashionable and cool
B. they are bored with driving cars
C. they are fond of being connected
D. it is much cheaper than a car
2.We can learn from the text that _______.
A. Twitter is a website for teens to make friends and achieve goals
B. ridesharing can be seen as a sign that people still count on each other
C. driving cars for teens means a plus and connecting with technology
D. having a car and cost-sharing symbolize more freedom for the author’s mother
3.Professor Juliet would agree that _______.
A. young people will sit waiting to be contacted by reading a passage
B. sharing economy is bound to be responsible for the recession
C. young people tend to share a car with strangers by means of Twitter
D. being connected via technology comes first for young people
4.The best title for the passage is probably _______.
A. Twitter, an Awesome Website
B. Cars or iPhone
C. Teens Use Twitter to Thumb Rides
D. Cool Teens on the Go

Well, parents, surprise! Lots of us are using Twitter and Facebook to find rides, and not just to school. It’s awkward to call a friend and ask for a ride, and half the time they’ll say, “Sorry, my car is full.” But with Twitter, you just tweet (贴子,留言) and look for other people heading the same way.
It may sound risky, but many teens stay within their own social circles to find rides, and don’t branch out beyond friends of friends when asking on Twitter. For me, I only rideshare with people I know, but to some young people, especially those taking longer trips, stranger danger is less of a concern.
The sharing economy got big during the recession(经济衰退). It allows people to access more goods and services using technology, while also allowing them to share cost. And that technology, for me, is what the car was for my mom, a gateway to more freedom.
According to the researchers at the University of Michigan, 30 years ago, eight in ten American 18-year-olds had a driver’s license. Today it’s six in ten. So it’s not that surprising that on my 16th birthday I wasn’t rushing to get a license. All I wanted was an iPhone. Juliet Schor (Sociology professor at Boston College) knows people my age love being connected and for young people driving means they have to disconnect from their technology, and that’s a negative. So if they could sit in the passenger side and still be connected, that’s going to be a plus.
To me, another plus is ridesharing represents something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, some of us still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on Twitter.
1.The writer usually rideshares with _____.
A. anyone heading the same way B. people he knows
C. friends of friends D. strangers of his age
2.Fewer young people choose to ride by themselves because _____.
A. driving means offering free rides to others.
B. getting a driving license becomes more difficult.
C. driving one’s own cars causes a negative impression.
D. driving makes them disconnected from technology.
3.We can conclude from the passage that _____.
A. the writer rideshares just to save money
B. people under 18 are not allowed to drive
C. silver Super Beetle is the writer’s favorite
D. the older generation had to fight for freedom
4.Which is the best title for the passage?
A. Teens use Twitter to thumb rides.
B. Tips on reducing risks in ridesharing.
C. Car is no longer a gateway to freedom.
D. New generation knows how to save money.
