Ever wonder how much a cloud weighs? What about a hurricane? A meteorologist(气象学者) has done some estimates and the results might surprise you.
Let's start with a very simple white puffy cloud — a cumulus cloud(积云). How much does the water in a cumulus cloud weigh? Peggy LeMone, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, did the numbers. "The water in the little cloud weighs about 550 tons," she calculates. "Or if you want to convert it to something that might be a little more meaningful … think of elephants."
The thought of a hundred elephants-worth of water suspended(悬浮的) in the sky begs another question — what keeps it up there?
"First of all, the water isn't in elephant-sized particles(微粒), it's in tiny tiny tiny particles," explains LeMone. And those particles float on the warmer air that's rising below. But still, the concept of so much water floating in the sky was surprising even to a meteorologist like LeMone. "I had no idea how much a cloud would weigh, actually, when I started the calculations," she says.
So how many elephant units of water are inside a big storm cloud—10 times bigger all the way around than the "puffy" cumulus cloud? Again, LeMone did the numbers: About 200,000 elephants.
Now, ratchet up(略微调高) the calculations for a hurricane about the size of Missouri and the figures get really massive(巨大的). "What we're doing is weighing the water in one cubic meter theoretically pulled from a cloud and then multiplying by(乘上) the number of meters in a whole hurricane," she explains.
The result? Forty million elephants. That means the water in one hurricane weighs more than all the elephants on the planet. Perhaps even more than all the elephants that have ever lived on the planet. The weight of is NOT mentioned in the passage.
A.a cumulus cloud | B.a tornado |
C.a hurricane | D.a storm cloud |
How did Peggy LeMone feel about the result of her calculations?
A.She found it not convincing. |
B.She thought it needed further calculations. |
C.She was quite surprised at it. |

What can be inferred from the passage?
A.A storm cloud weighs about 200,000 elephants. |
B.The water in a hurricane weighs more than that in any other kind of cloud. |
C.There are less than forty million elephants living on the earth. |
D.The water in the cloud is in very tiny partials. |
What is the best title for the passage?
A.How Much a Cloud Weighs | B.How Much a Hurricane Weighs |
C.Surprising Results | D.Elephants in the Sky |
Although women lead healthier, longer lives, the cruel opinion that they become "old” sooner than men is widespread in the workplace, research shows.
A survey of more than 2,600 managers and personnel professionals showed that age discrimination is not only common in the workplace, but is shot through with inconsistencies (矛盾).
Six in ten managers reported being a victim of age discrimination -- usually because they were turned down for a job for being too old or too young. Yet more than a fifth admitted that they used age as an important standard.
Although the survey found widespread agreement that older workers were better than younger colleagues when it came to reliability, commitment (承担义务), loyalty (忠诚) and customer service, these qualities were not necessarily considered to be worthy of advancement.
A large number of persons believed that workers between 30 and 39 had the best promotion chances, with only 2 per cent giving examples of 50-year-olds or above.
There was evidence that people were considered old at different ages in different jobs. A young man working in IT said he was considered too old by the age of 28.
In fact there was no evidence to suggest that older workers were less valuable to companies than younger workers, in fact the opposite was often true because older workers often brought experience.
The findings also suggested that the Government's ideas on age in the workforce may also be out of step with reality.
64.Which is the discrimination mentioned in this passage?
A. The healthier women are, the sooner they will lose their jobs.
B. Society knows women should be respected, but it doesn't offer them any jobs.
C. Female managers respect male workers, but male managers don't respect female workers.
D. victims of age discrimination consider age as an important standard.
65.Older workers are better than younger colleagues because they have many advantages except that they are _____.
A. dependable B. married C. faithful D. helpful
66.Why does the writer mention a young man working in IT?
A. Because the writer thinks it a pity that this young man is old.
B. Because it's an example of different age standards in different jobs.
C. Because IT industry is developing too fast.
D. Because the writer doesn't think the young man is old.
67. Which statement is true according to the writer's attitude?
A. The present age standard doesn't go with reality.
B. The present age standard is reasonable.
C. women should work longer than men.
D. Young workers should learn from old workers.
Economists usually study markets.Now,two Americans have won the Nobel Prize in economics for not studying markets.They will share almost one and a half million dollars for their analysis of economic governance(治理).The winners are Elinor Ostrom of Indiana University in Bloomington and Oliver Williamson of the University of California,Berkeley.The prize in economic sciences has gone to 63 men since it was first awarded 40 years ago.Elinor Ostrom is the first woman.And,like other winners over the years,her training is not limited to economics.She is a professor of political science and of public and environmental affairs.
Today,economic theory suggests that good resource management requires ownership,either private or public.If not,the thinking goes,then self-interest will lead to overuse and destruction of shared resources.Ecologist Garrett Hardin described this idea in 1968 as“the tragedy of the commons.”
Elinor Ostrom showed how local decision making can lessen the tragedy.Her research has deepened understanding of how people balance their needs with those of others who depend on the same resources.
She studied communities like farmers in Southern California who depended on a common water supply. She documented how people who use resources often develop ways to share them.One example is forest management.She says,“One of the absolutely key,most important variables(变量)as to
whether or not a forest survives and continues is whether local people monitor each other and its use.Not officials,locals.”
Oliver Williamson has studied big companies and found that they often are better than markets at doing complex jobs.Under his theory,businesses act as structures for conflict resolution.
For example,companies that own their suppliers can avoid long-term contracts and disputes over prices.This can make production more efficient and make better use of limited resources.But businesses can also abuse their power.Professor Williamson says the best way to deal with this is not by limiting the size of companies,but through industry regulation.
The Royal Swedish Academy of Sciences said economists need to do more than study markets and prices.The Nobel judges urged more research like the kind they recognized with this year’s award.
60.According to Elinor Ostrom,.
A.the tragedy of the commons is caused by local decision
B.private ownership can cause the tragedy of the commons
C.overuse of shared resources can cause the tragedy of the commons
D.it is not the officials but the local people who can do something to avoid the tragedy
61.This year’s Nobel Prize for economics is shared by.
A.Elinor Ostrom and Oliver Williamson B.Elinor Ostrom and Garrett Hardin
C.Oliver Williamson and Garrett Hardin D.63 economic scientists
62.Professor Williamson proved that long-term contracts and disputes over prices can be
avoided by big companies by.
A.1imiting the size of other companies
B.providing sufficient production
C.sharing resources with their own suppliers
D.setting up their own industry regulation
63.Which of the following can serve as the best title for the passage?
A.Two American Economists Won the Nobel Prize for Studying Markets.
B.Researchers of Economic Governance Won the Nobel Prize for Economics.
C.First Woman to Win the Nobel Prize for Economic Strategies.
D.The Tragedy of the Commons and the Big Businesses.
It had been a long time since I had been to Jacksonville, Florida.I had driven to town hoping to see the old barber shop where my hair had been cut as a child.
I parked my truck and decided to try and locate a telephone to see if the Florida Barber College had moved to a new location.
After walking about a block I saw an open shoe store.I walked inside and asked if I could use their telephone book.Unable to find a listing for the Barber College, I picked out the number of a local beauty salon, hoping they might tell me if the barber college was still in business.The number was busy, so I decided to wait and try again in a few minutes.
As the salesman and I stood talking the front door opened and a young man about twenty came into the store pushing himself in a wheelchair.“I need a new pair of shoes,” said the customer.As he turned the corner, there was a blanket across his lap.I was shocked to see that the young man had no legs.
“A gift for a friend?” I asked the boy.“No,” he replied.They are for me,” he continued, with a smile on his face.I just smiled back and watched to see what would happen next.
“What type of shoe would you like?” asked the clerk.“How about a pair of cowboy boots?”The man pointed to the back wall where three or four pairs of boots were displayed.The salesman, sharply turning, headed off to the backroom.
“Isn’t this fun?” the boy asked me.I moved my hand to let him know that I did not understand his question.“When I was a kid, my parents used to buy me a new pair of shoes every year.That was such a wonderful feeling.Something I have never forgotten.The smell of the leather and the pride I felt when I walked around the store showing off my new shoes.”
The salesman came walking down the aisle with a large box.He sat it down on the floor, took out one boot and handed it to the young man.The boy closed his eyes.He placed the boot against his nose, and drew in a large breath.I did not know what to say as tears began to fall on the young man’s cheeks.“What type of accident did you have?” I asked him.“Farm accident,” he said, as he tried to clear his voice.
“Do you want the cowboy boots?” the salesman asked him.
“Oh, yes!” he answered.
“I see buying a new pair of shoes still gives you that good feeling you talked about,” I told the young man, as I smiled.
“Yes it does.” he said “And I may have someone, and his feet to share it with some day.”

Each time I see a balloon, my mind flies back to a memory of when I was a six-year-old girl. It was a rainy Sunday and my father had recently died. I asked my mom if Dad had gone to heaven. "Yes, honey. Of course," she said.
"Can we write him a letter?"
She paused, the longest pause of my short life, and answered, "Yes."
My heart jumped. "How? Does the mailman go there?" I asked.
"No, but I have an idea." Mom drove to a party store and returned with a red balloon. I asked her what it was for.
"Just wait, honey. You'll see." Mom told me to write my letter. Eagerly, I got my favorite pen, and poured out my six-year-old heart in the form of blue ink. I wrote about my day, what I learned at school, how Morn was doing, and even about what happened in a story I had read. For a few minutes it was as if Dad were still alive. I gave the letter to Mom. She read it over, and a smile crossed her face.
She made a hole in the corner of the letter where she looped(缠绕) the balloon string. We went outside and she gave me the balloon. It was still raining.
"Okay, on the count of three, let go. One, two, three."
The balloon, carrying my letter, darted(猛冲) upward against the rain. We watched until it was swallowed by the mass of clouds.
Later I realized, like the balloon, that Dad had never let his sickness get him down. He was strong. No matter what he suffered, he'd persevere, dart up, and finally transcend(超越) this cold world and his sick body. He rose into sky and became something beautiful. I watched until the balloon disappeared into the gray and white and I prayed that his strength was hereditary(遗传的). I prayed to be a balloon.

The followingpassage is a healthy prescription (处方) of how we can approachlife. It is not about being famous or being wealthy or aboutourgoodlooks. Truly,it is all about love. There are times when we feel as if we are separated from the rest. This feeling creates a mental prison. Therefore,we should try to work hard tointernally (内在地)liberate ourselvesby widening our circle of pity to accept all living things.
“Open your heart to others andtry to understand,
When someone reaches for you, hold out to them your hand,
Follow your heart,nomatter what otherpeople say,
Do things that make you able to smile throughout your day,
Treat other people, the way you would like them to treat you,
Do what you know is right andto your heart and self stay true,
Remember what life isall about, it is how you make people feel,
What you do, where you go, and making dreams become real,
Helping people through, in hard times of pain and strife,
What you do for others, is what is important in this life.
Look deeper anddon’t judge people by what ison the outside,
It iswhat is inside that counts and what people often hide,
Care, help, love, be honest, and be kind,
Withpurity and goodness within yourself,it ishappiness you willfind.
Do all you can in the time you have, you won’t always be around,
Recapture the joy of little things, that once were easily found,
And if you can do all this and live a life of love,
You willbe helped through life, by all those up above.”

“There are two ways to live life. One is as though nothing is a miracle (奇迹). The other is as though everything is a miracle.”
