When I was in middle school, my social studies teacher asked me to enter a writing contest. I said no without thinking. I did not love writing. My family came from Brazil, so English was only my second language. Writing was so difficult and painful for me that my teacher had allowed me to present my paper on the sinking of the Titanic by acting out a play, where I played all the parts. No one laughed harder than he did.

So, why did he suddenly force me to do something at which I was sure to fail? His reply: “Because I love your stories. If you’re willing to apply yourself, I think you have a good shot at this.” Encouraged by his words, I agreed to give it a try.

I chose Paul Revere’s horse as my subject. Paul Revere was a silversmith (银匠) in Boston who rode a horse at night on April 18, 1775 to Lexington to warn people that British soldiers were coming. My story would come straight from the horse’s mouth. Not a brilliant idea, but funny; and unlikely to be anyone else’s choice.

What did the horse think, as he sped through the night? Did he get tired? Have doubts? Did he want to quit? I sympathized immediately. I got tired. I had doubts. I wanted to quit. But, like Revere’s horse, I kept going. I worked hard. I checked my spelling. I asked my older sister to correct my grammar. I checked out a half dozen books on Paul Revere from the library. I even read a few of them.

When I handed in the essay to my teacher, he read it, laughed out loud, and said, “Great. Now, write it again.” I wrote it again, and again and again. When I finally finished it, the thought of winning had given way to the enjoyment of writing. If I didn’t win, I wouldn’t care.

注意:
1. 续写词数应为150个左右；

A few weeks later, when I almost forgot the contest, there came the news.

2 . On March 7, 1907, the English statistician Francis Galton published a paper which illustrated what has come to be known as the “wisdom of crowds” effect. The experiment of estimation he conducted showed that in some cases, the average of a large number of independent estimates could be quite accurate.

This effect capitalizes on the fact that when people make errors, those errors aren’t always the same. Some people will tend to overestimate, and some to underestimate. When enough of these errors are averaged together, they cancel each other out, resulting in a more accurate estimate. If people are similar and tend to make the same errors, then their errors won’t cancel each other out. In more technical terms, the wisdom of crowds requires that people’s estimates be independent. If for whatever reasons, people’s errors become correlated or dependent, the accuracy of the estimate will go down.

But a new study led by Joaquin Navajas offered an interesting twist (转折) on this classic phenomenon. The key finding of the study was that when crowds were further divided into smaller groups that were allowed to have a discussion, the averages from these groups were more accurate than those from an equal number of independent individuals. For instance, the average obtained from the estimates of four discussion groups of five was significantly more accurate than the average obtained from 20 independent individuals.

In a follow-up study with 100 university students, the researchers tried to get a better sense of what the group members actually did in their discussion. Did they tend to go with those most confident about their estimates? Did they follow those least willing to change their minds? This happened some of the time, but it wasn’t the dominant response. Most frequently, the groups reported that they “shared arguments and reasoned together”. Somehow, these arguments and reasoning resulted in a global reduction in error. Although the studies led by Navajas have limitations and many questions remain, the potential implications for group discussion and decision-making are enormous.

3 . Personal Forgiveness

Taking responsibility for mistakes is a positive step, but don’t beat yourself up about them. To err (犯错) is human.     1     You can use the following writing exercise to help you do this.

In a journal or on a piece of paper, put the heading “Personal strengths.”     2     Are you caring? Creative? Generous? A good listener? Fun to be around? They don’t have to be world-changing, just aspects of your personality that you’re proud of.

At the top of a second page, put the heading “Acts of kindness.” On this one, list all the positive things you’ve done for others. It might be the time when you helped a friend with their homework, when you did the ironing without being asked, or when you baked cookies after the family had had a tiring day.     3    

You could ask a friend or family member to help add to your list.     4     That way, you could exchange thoughts on what makes each of you special and the aspects of your personality that shine through. In fact, don’t wait until you’ve made a mistake to try this — it’s a great way to boost self-confidence at any time.

It’s something of a cliché (陈词滥调) that most people learn not from their successes but their mistakes. The thing is, it’s true.     5     We’ re all changing and learning all the time and mistakes are a positive way to develop and grow.

A．A little self-forgiveness also goes a long way.

B．Now list all the characteristics you like about yourself.

C．They might even like to have a go at doing the exercise.

D．It’s just as important to show yourself some forgiveness.

E．It doesn’t mean you have to ignore what’s happened or forget it.

F．Whatever it is, no matter how small it might seem, write it down.

G．Whatever the mistake, remember it isn’t a fixed aspect of your personality.

4 . When John Todd was a child, he loved to explore the woods around his house, observing how nature solved problems. A dirty stream, for example, often became clear after flowing through plants and along rocks where tiny creatures lived. When he got older, John started to wonder if this process could be used to clean up the messes people were making.

After studying agriculture, medicine, and fisheries in college, John went back to observing nature and asking questions. Why can certain plants trap harmful bacteria (细菌)? Which kinds of fish can eat cancer-causing chemicals? With the right combination of animals and plants, he figured, maybe he could clean up waste the way nature did. He decided to build what he would later call an eco-machine.

The task John set for himself was to remove harmful substances from some sludge (污泥). First, he constructed a series of clear fiberglass tanks connected to each other. Then he went around to local ponds and streams and brought back some plants and animals. He placed them in the tanks and waited. Little by little, these different kinds of life got used to one another and formed their own ecosystem. After a few weeks, John added the sludge.

He was amazed at the results. The plants and animals in the eco-machine took the sludge as food and began to eat it! Within weeks, it had all been digested, and all that was left was pure water.

Over the years, John has taken on many big jobs. He developed a greenhouse — like facility that treated sewage (污水) from 1,600 homes in South Burlington. He also designed an eco-machine to clean canal water in Fuzhou, a city in southeast China.

“Ecological design” is the name John gives to what he does. “Life on Earth is kind of a box of spare parts for the inventor,” he says. “You put organisms in new relationships and observe what’s happening. Then you let these new systems develop their own ways to self-repair.”

1. What can we learn about John from the first two paragraphs?

A．He was fond of traveling.	B．He enjoyed being alone.
C．He had an inquiring mind.	D．He longed to be a doctor.

2. Why did John put the sludge into the tanks?

A．To feed the animals.	B．To build an ecosystem.
C．To protect the plants.	D．To test the eco-machine.

3. What is the author’s purpose in mentioning Fuzhou?

A．To review John’s research plans.	B．To show an application of John’s idea.
C．To compare John’s different jobs.	D．To erase doubts about John’s invention.

4. What is the basis for John’s work?

A．Nature can repair itself.	B．Organisms need water to survive.
C．Life on Earth is diverse.	D．Most tiny creatures live in groups.

10 . With gas prices rising and airport security lines snaking longer than ever, why not book your next domestic vacation on a train? Compared to other alternatives, it’s comfortable and relaxing. Here is some advice on how to make a trip by rail as pleasant as possible.

Plan ahead. Most long-distance trains, especially the sleeping car accommodations, sell out very quickly.     1     But no matter when you travel, it’s a good idea to make your reservations at least 90 days in advance.

Use a travel agent. Consider turning your travel plan over to a travel agent and letting him double-check all the details, make suggestions, and then handle the actual reservations. A good one can sometimes find you discounted tickets.     2     Then you won’t have to walk through several cars on a moving train three times a day for your meals.

Bring a blanket. When you’re riding on trains, you won’t be provided with a blanket for free, even if your trip is an overnight one.     3     In the summer in particular, the air conditioning can make them quite cold.

Arrive early. Most trains operate just once a day and some run only three times a week, so missing yours can be a disaster.     4     Note: The times listed on the schedules are departure times, not arrival times.

Have fun.     5     Read a book, knit, do a crossword puzzle, or simply watch the world unfold outside the window. To calculate your speed as you do, divide 3,600(the number of seconds in an hour)by the number of seconds it takes you to travel one mile(the distance between two mileposts). If it takes the train 53 seconds to travel one mile, you’re going 67.92 mph.

A．Train trips aren’t for impatient types.

B．You’ll have views from both sides of the train.

C．The temperature on rail cars is often hard to control.

D．That’s particularly true during busy summer months.

E．You might have to wait longer than 24 hours to catch the next one.

F．Chances are the cost will be a lot less than the cost of one bedroom.

G．He may also book you in a sleeping car that’s right next to the diner.
