His company   14   most of the awards in the first national competition for school uniforms last month in Nanning, Guangxi.

“Besides, high quality calls for a high price,” said Chen. “But in some schools, the annual (一年一度) expense for each student’s uniform is only 50 to 60 yuan. How can we produce high quality clothes with so   15   money?”

Even with these problems, efforts have been made   16   the situation, according to Zhai Shiliang,   17   of the School Uniform Administration and Service Center in Beijing.

The birthrate in Europe has been in a steady decrease since the 1960s. European countries, realizing crisis is at hand, are providing great encouragement for parents to create more babies in the 21st century.

Affairs Ministry concluded last year that,    11    cash encouragement, some women just don’t want to be    12    holding the baby. “What we know is that it’s good for the    13___ if men and women share the burden of having children,” says Soren Kindlund, family policy adviser at the Swedish ministry.    14    Swedish parents can take their paid leave as they wish, men use a mere 12% of it; 60% of fathers do not take even a(n)    15 _   day off work.

Experts fear that the tendency for women to use most of the parental leave could make employers    16    to give young women the permanent jobs they need to qualify for paid maternity leave (產(chǎn)假). In January, Sweden decided to allow new fathers two months’ paid leave, with a warming: use it or    17    it.

Kindlund admits that men are under   18    to stay at work, even though parental pay comes out of the public purse. “It’s not popular among bosses and perhaps with other men in the workplace,” he says. “But it’s good for the father and for the child if they can    19    a relationship.”

In Norway, a(n)   20    policy has worked wonders. 70% of dads in Norway now take parental leave, and the birthrate of 1.85 children per woman is one of the highest in Europe.

If you live in America in the 21st century you'll probably have to listen to a lot of people tell you how busy they are. It's become the default response when you ask anyone how they are doing:"Busy!""Crazy busy!".It is,pretty obviously,a boast disguised as a complaint. And the common response is a kind of congratulation:"That's a good problem to have,"or"Better than the opposite."

Notice it isn't generally people pulling back-to-back shifts in the ICU or commuting by bus to three minimum-wage jobs who tell you how busy they are.What those people are is not busy but tired.Exhausted!Dead on their feet.It's almost always people whose busyness is purely self-imposed:work and obligations they've taken on voluntarily,classes and activities they've "encouraged" their kids to participate in.They're busy because of their own ambition or drive or anxiety,because they're addicted to busyness and dread that they might have to face in its absence.

Almost everyone I know is busy. They feel anxious and guilty when they aren't either working or doing something to promote their work.It's something they have chosen.Busyness serves as a kind of existential reassurance(令人安心的保證），a measure against emptiness,obviously your life cannot possibly be silly or tiny or meaningless if you are so busy,completely booked,in demand every hour of the day.

Idleness is not just a vacation.It is as necessary to the brain as vitamin D is to the body,and deprived of it we suffer a mental affliction as ugly as rickets.The space and quiet that idleness provides is a necessary condition for standing back from life and seeing it whole,for making unexpected connections and waiting for the wild summer lightning strikes of inspiration."Idle dreaming is often the essence of what we do,"wrote Thomas Pynchon.Archimedes' "Eureka"in the bath, Newton's apple :history is full of stories of inspirations that come in idle moments.

1.When many Americans say"Crazy busy", they mean______.

A．they are really tired of their present situation

B．they are really proud of their present life

C．they are complaining about their current work

D．their life are full of all kinds of problems

2.The writer mentions Archimedes' "Eureka"and Newton's apple to show that________.

A．history is full of interesting stories

B．Archimedes and Newton were very busy, so they made great discoveries

C．people may get inspiration when they are idle

D．inspirations come from hard work

3.The word "its" in the second paragraph refers to_______________________________.

A．a(chǎn)mbition          B．a(chǎn)nxiety           C．busyness          D．dread

4.From the article,we can infer that ___________________________________.

A．generally people pulling back-to-back shifts in the ICU tell you they are busy

B．"Dead on their feet" means "being tired out"

C．a(chǎn)ll the kids are self-imposed due to the drive and motivation

D．The author seems to agree that idleness is better than busyness

As the railroads and the highways shaped the American West in the past centuries, a new electrical generating(發(fā)電)and transmission (輸送) system for the 21st century will leave a lasting mark on the West, for better or worse. Much of the real significance of railroads and highways is not in their direct physical effect on the scenery, but in the ways that they affect the surrounding community. The same is true of big solar plants and the power lines that will be laid down to move electricity around.

The 19 th century saw land grants(政府撥地) offered to railroad companies to build the transcontinental railroads, leaving public land in between privately owned land. In much of the West, some of the railroad sections were developed while others remained undeveloped, and in both cases the landownership has presented unique challenges to land management. With the completion of the interstate highway system, many of the small towns, which sprang up as railway stops and developed well, have lost their lifeblood and died.

Big solar plants and their power lines will also have effects far beyond their direct footprint in the West. This is not an argument against building them. We need alternative energy badly, and to really take advantage of it we need to be able to move electricity around far more readily than we can now.

So trade-offs will have to be made. Some scenic spots will be sacrificed. Some species(物種) will be forced to move, or will be carefully moved to special accommodations. Deals will be struck to reduce the immediate effects.

The lasting effects of these trade-offs are another matter. The 21st century development of the American West as an ideal place for alternative energy is going to throw off a lot of power and money in the region. There are chances for that power and money to do a lot of good. But it is just as likely that they will be spent wastefully and will leave new problems behind, just like the railroads and the highways.

The money set aside in negotiated trade-offs and the institutions that control it will shape the West far beyond the immediate footprint of power plants and transmission lines. So let’s remember the effects of the railroads and the highways as we construct these new power plants in the West.

1.What was the problem caused by the construction of the railways?

A．Small towns along the railways became abandoned.

B．Land in the West was hard to manage.

C．Some railroad stops remained underused.

D．Land grants went into private hands.

2.What is the major concern in the development of alternative energy according to the last two paragraphs?

A．The use of money and power.

B．The transmission of power.

C．The conservation of solar energy.

D．The selection of an ideal place.

3.What is the author’s attitude towards building solar plants?

A．Disapproving.      B．Approving.         C．Doubtful.          D．Cautious.

4.Which is the best title for the passage?

A．How the Railways Have Affected the West

B．How the Effects of Power Plants Can Be Reduced

C．How Solar Energy Could Reshape the West

D．How the Problems of the Highways Have Been Settled
