UW’s Jason Shogren and Linda Thunstrom, along with Jonas Nordstrom of the Lund University School of Economics and Management, have documented that two-adult households with children emit over 25 percent more carbon dioxide than two-adult households without children.
The study involved an analysis of expenditures on goods and services by households in Sweden. The researchers found that parents with children at home consume goods and services that emit CO2 in the areas of food, such as meat, and transportation, such as gasoline, at higher rates than childless households.
The economists note that time constraints (约束) become more demanding, and convenience may become more important, when people have children.
“Parents may need to be in more places in one day,” resulting in people driving themselves instead of using public transportation or bicycling, the researchers wrote. “They also need to feed more people. Eating more pre-prepared, red meat carbon-intensive meals may add convenience and save time.”
The distinction in the carbon footprints of Swedish households with and without children is particularly striking, as concerns about climate change are more pronounced in Sweden than most other developed counties. Most Swedes believe climate change is real and have accepted sizable CO2 taxes, and households with children are given financial aid, which helps to alleviate some of the time shortage for parents to a certain extent.
“If we’re finding these results in Sweden, it’s pretty safe to assume that the distinction in carbon footprints between parents and nonparents is even bigger in most other Western countries,” Thunstrom says.
“Becoming a parent can transform a person, he or she thinks more about the future and worries about future risks imposed on their children and of spring,” Shogren says. “But, while having children might be transformational, our results suggest that parents’ concerns about climate change do not cause them to be ‘greener’ than non-parent adults.”
1.According to the study, compared with the households without children, the households with children __________.
A.emit more carbon dioxide
B.consume more goods and services
C.attach more importance to the quality of goods and services
D.are less concerned about carbon footprints
2.Why do two-adult households with children have higher carbon footprints?
A.They prefer to eat red meat prepared in advance.
B.They aren’t concerned about climate change.
C.They drive cars more as a consequence of time pressure.
D.They need to purchase more goods and services.
3.The underlined word “alleviate” in paragraph 5 refers to __________.
A.solve B.heighten C.worsen D.ease
4.What is the main idea of the passage?
A.Being a parent will cause a person to be more concerned about carbon emission.
B.Carbon footprints grow with parenthood because of increased time constraints and the need for convenience.
C.The increasing expenditures on goods and services by households help raise the awareness of carbon footprints.
D.The difference in carbon footprints between parents and nonparents is much severer in other western countries than in Sweden.

With large and small keyboards everywhere, neither children nor adults need to write much of anything by hand. That’s a big problem. Study after study suggests that handwriting is important for brain development — helping kids get fine motor skills and learn to express and create ideas. Yet the time devoted to teaching penmanship in most schools has shrunk to just one hour a week. Is it time to give up handwriting? Have a look at the link between the brain and penmanship, and you may get the answer.
A test among students in grades 2, 4 and 6 found that they not only wrote faster by hand than by keyboard, but also created more ideas when composing essays with handwriting. And other research shows that the finger movements required to write by hand activate brain areas involved with thought, language, and short-term memory.
A recent Indiana University study had one group of children practice writing letters by hand while a second group just looked at those letters. Then, both groups of kids entered a functional MRI (核磁共振) that scanned their brains as the researchers showed them the same letters. Researchers found that the brain activity in the first group was far more advanced and “adult-like”.
Handwriting also affects other people’s way they think of adults and children. Several studies have shown that the same average essay will score much higher if written with good penmanship and much lower if written out in poor handwriting. These studies have also found that people judge the quality of a person’s ideas based on his or her handwriting. And the consequences are real: On standardized tests with handwritten sections, like the SAT, all essays that are considered hard to recognize gets a big zero.
Studies show that this isn’t only an English-language phenomenon. Chinese and Japanese youths are suffering from “character amnesia”. They can’t remember how to write characters, thanks to computers and text messaging. Some experts fear that Chinese writing and reading are so closely linked in the brain that China’s reading ability as a nation could suffer.
1.According to the passage, it can be learned that ________________.
A. many researches have been done on handwriting
B. essays can’t be composed without handwriting
C. all children write faster by keyboard than by hand
D. most schools are trying to teach more handwriting
2. What does the Indiana University study imply?
A. Children should practice writing letters
B. Handwriting can increase brain activity
C. It’s good for children to enter a functional MRI
D. Letters should often be shown to children
3.What does the 4th paragraph mainly talk about?
A. Handwriting affects both adults and children.
B. Handwriting helps a person write better essays.
C.SAT should be done with good handwriting.
D. Good handwriting makes a person seem smarter.
4. Which of the following statements is TRUE?

B. The quality of your ideas depends on your handwriting.

Along with global warming and the Ebola virus，this year, something far less life-and society-threatening also spiraled out of control：email．
It was long ago invented as something to make us more productive．But what productivity expert would ever say that it's a good thing that instead of working，we now“answer email? Or that on some days，I am unwilling to leave my desk to head into a meeting because it means taking my finger off the keyboard and knowing 1 will return to a flood of new messages waiting patiently for my total attention?
Some people struggle for“inbox zero”．But like many people，I now get so much junk mail that if I were to adopt such a goal，I would spend every workday doing nothing but deleting emails．To make sure nothing important gets buried，I have developed an embarrassinglv old system of keeping a pen-and-paper list of emails that need responses on a series of Post-It notes．As far back as 2007，Fred Wilson famously declared “email bankruptcy”．I'm close to doing the Same．
But I may not need to．I predict that 2015 will mark the beginning of the end of emails．Already, some tools have emerged(出现)over the years，like software Freedom which disables access to the Internet for chosen periods of time．Corporations have gradually been adopting stricter email policies：A few years ago，Volkswagen said it would stop sending emails from its servers to company-owned BlackBerrys after the end of its workday．
But this great hope is largely the optimist in me speaking，and I give this prediction small chances compared to some of our others．As Tony Hsieh once told me，the problem with email is that it is a“good—enough”solution．Some technologies stay around just because there isn’t anything better．It’s probably right．But my wish is that 2015 is the year when truly effective email management solutions go from good to great-and that email volume goes from crazy to reasonable．We’ll a11 be better for it．
1.The underlined word “spiraled” in Paragraph l probably means “_____________”.
A．increased rapidly B．moved in circle
C．changed unexpectedly D．appeared suddenly
2.The writer is unwilling to attend a meeting because____________.
A．he has to return with quantities of emails
B．answering emails calls for great attention
C．more emails will flood in waiting for him to check
D．he doesn’t want to take his fingers off the keyboard
3.From Paragraph 3，we may infer that____________.
A．the goal “inbox zero” is hard to obtain
B．the writer is devoted to deleting emails
C．pens and paper are highly favored at work
D．Fred Wilson famously declared “email bankruptcy”
4.The writer may agree that____________.
A．emails will come to an end
B．emails will still hold a place
C．existing email management is perfect
D．emails will never be sent to BlackBerrys
