El Nifio, a Spanish term for “the Christ child", was named by South American fishermen who noticed that the global weather pattern, which happens every two to seven years, reduced the amount of fishes caught around Christmas. El Nifio sees warm water, collected over several years in the western Pacific, flow back eastwards when winds that normally blow westwards weaken, or sometimes the other way round.

        The weather effects, both good and bad, are felt in many places. Rich countries gain more from powerful Nifio, on balance, than they lose. A study found that a strong Nifio in 1997 helped American's economy grow by $15 billion, partly because of better agricultural harvest, farmers in the Midwest gained from extra rain. The total rise in agricultural incomes in rich countries is greater than the fall in poor ones.

          But in Indonesia extremely dry forests are in flames. A multi-year drought (干旱）in south-east Brazil is becoming worse. Though heavy rains brought about by El Nino may relieve the drought in California, they are likely to cause surface flooding and other disasters.

The most recent powerful Nino, in 1997-98, killed around 21,000 people and caused damage worth $36 billion around the globe. But such Ninos come with months of warning, and so much is known about how they happen that governments can prepare. According to the Overseas Development Institute(ODI), however, just 12% of disaster-relief funding in the past two decades has gone on reducing risks in advance, rather than recovery and rebuilding afterwards.This is despite evidence that a dollar spent on risk-reduction saves at least two on reconstruction.

Simple improvements to infrastructure (基础设施）can reduce the spread of disease. Better sewers (下水道）make it less likely that heavy rain is followed by an outbreak of the disease of bad stomach. Stronger bridges mean villages are less likely to be left without food and medicine after floods. According to a paper in 2011 by Mr. Hsiang and co-authors, civil conflict is related to El Nino's harmful effects—and the poorer the country, the stronger the link. Though the relationship may not be causal, helping divided communities to prepare for disasters would at least reduce the risk that those disasters are followed by killing and wounding people. Since the poorest are least likely to make up for their losses from disasters linked to El Nino, reducing their losses needs to be the priority.

    A city child's summer is spent in the street in front of his home, and all through the long summer vacations I sat on the edge of the street and watched enviously the other boys on the block play baseball. I was never asked to take part even when one team had a member missing—not out of special cruelty, but because they took it for granted I would be no good at it. They were right, of course.

    I would never forget the wonderful evening when something changed. The baseball ended about eight or eight thirty when it grew dark. Then it was the custom of the boys to retire to a little stoop(门廊) that stuck out from the candy store on the corner and that somehow had become theirs. No grownup ever sat there or attempted to. There the boys would sit, mostly talking about the games played during the day and of the game to be played tomorrow. Then long silences would fall and the boys would wander off one by one. It was just after one of those long silences that my life as an outsider changed. I can no longer remember which boy it was that summer evening who broke the silence with a question: but whoever he was, I nod to him gratefully now. “What's in those books you're always reading?” he asked casually. “Stories,” I answered. “What kind?” asked somebody else without much interest.

    Nor do I know what drove me to behave as I did,for usually I just sat there in silence, glad enough to be allowed to reain among them; but instead of answering his question, I told them for two hours the story I was reading at the moment. The book was Sister Carrie. They listened bug-eyed and breathless. I must have told it well, but I think there was another and deeper reason that made them to keep an audience. Listening to a tale being told in the dark is one of the most ancient of man's entertainments, but I was offering them as well, without being aware of doing it, a new and exciting experience.

    The books they themselves read were the Rover Boys or Tom Swift or G.A.Henty. I had read them too, but at thirteen I had long since left them behind. Since I was much alone I had become an enthusiastic reader and I had gone through the books-for-boys series. In those days there was no reading material between children's and grownups'books or I could find none. I had gone right fromTome Swift and His Flying Machine to Theodore Dreiser and Sister Carrie. Dreiser had hit my young mind, and they listened to me tell the story with some of the wonder that I had had in reading it.

    The next night and many nights thereafter, a kind of unspoken ritual (仪式) took place. As it grew dark, I would take my place in the center of the stoop and begin the evening's tale. Some nights, in order to taste my victory more completely, I cheated. I would stop at the most exciting part of a story by Jack London or Bret Harte, and without warning tell them that that was as far as I had gone in the book and it would have to be continued the following evening. It was not true, of course; but I had to make certain of my new-found power and position. I enjoyed the long summer evenings until school began in the fall. Other words of mine have been listened to by larger and more fashionable audiences, but for that tough and athletic one that sat close on the stoop outside the candy store, I have an unreasoning love that will last forever.

    Webber is a labor economist. His latest research offers guidance on how to keep students on target to earn a degree from a college or university. Among his findings: It is important, whenever possible, for college students to complete their degree program in four years. Also, getting a part-time job is probably a good thing to help finance a college education. But too much time spent working on a job makes it less likely the student will graduate.

    One thing, Webber said, is financial aid that helps many students pay for college. Scholarships and other assistance generally stop after four years. So the cost of each additional year in school is likely to come almost entirely from the student and/or parents.

    But there are other reasons why taking more than four years is a problem, as Webber notes. It's because life gets in the way, other things happen. He means the longer you stay in college, the more likely that some unexpected event will affect your studies. It could be a loved one getting sick, a parent losing a job, or the student running out of money for college.

    Only about four in 10 graduated within four years. It is also important that students have enough time to complete their college classes, Webber added. His research suggests part-time work of 15 hours or less will not cause harm to the student's scholastic performance. But his research shows students who work 20 hours or more a week are about 15 percent less likely to graduate on time, or to graduate at all.

    His belief is that students active in college athletic programs would face the same problem. It is common, he said, for student athletes to spend 20 hours or more for training, travel and to compete against athletes or teams from other schools.

    It was a cold winter. The wind blew all night and the snow was blinding. When morning came, my three children and I got up and made our way to the windows. As we looked out of the window, we saw that the henhouse was gone. Our three hens had been blown away by the cold wind.

    I looked at the emptiness outside. Then I saw all three chickens sitting around the edge of a white bucket. I couldn't believe my eyes! How was this violent wind not blowing them into the field beyond？I quickly pulled on long snow pants and heavy winter coat, wrapped a scarf around my neck and stuck my feet into large boots.

    I shouted at the wind as it blew. I was alone, struggling in the snow. They stared out the window into the vast white sea of snow, peering at any sign of movement. Outside I heard the sound of my boots as I walked against the wind.

    As the snow circled around me, I steadily made my way to the soft cluck-cluck-cluck sound my hens always made. When I reached them, I saw that their little feet were holding on to the edge of the bucket, heads bent forward and away from the wind. I gently lifted each hen and put it carefully into the warm inside. Then I began the freezing walk back to the small shed directly behind our house. One by one I laid my chickens on the cold floor, and they began to cluck softly.

    As I shut the shed doors, my eyes went directly to the window where my children were watching. They jumped up and down cheering, and so did I! I wasn't some dragon slayer(屠龙者) from a fairy tale. I was simply a mom, but the look on my children's faces told me that they thought I was a hero mom.

    About 30 years ago, I left Cuba for the United States with my son. After getting settled finally in Brunswick, New Jersey, I enrolled (注册) my son in kindergarten. Several weeks later, my son's teacher asked me to meet him at his office.

    In the teacher's office, and exchange of greetings was followed by his questions: "Is your son mentally retarded (弱智的)? Does he suffer from any kind of mental disability?"

    Was he talking about my wonderful Scola? No, no, it can't be. What a helpless, lonely moment! I told him that Scola was a quiet, sweet little boy, instead. I asked him why he was asking me all these questions.

    My son could not follow the teacher's directions, he told me, and thus, Scola was disrupting the class. Didn't he know my son did not speak English yet? He was angry: "Why hasn't your son been taught to speak English? Don't you speak English at home?"

    No, I didn't speak English at home, I replied. I was sure my son would learn English in a couple of months, and I didn't want him to forget his native language. Well, wrong answer!

    What kind of person would not speak in English to her son at home and at all times? "Are you one of those people who come to this country to save dollars and sent them back to their country, never wanting to be a part of this society?"

    Needless to say, I tried to tell him I was not one of "those people." Then he told me the meeting was over, and I left.

    As I had expected, my son learned to speak English fluently before the school year was over. He went on to graduate from college and got a job, earning close to six figures. He travels widely and leads a well-adjusted, contented life. And he has benefited from being bilingual (双语的).

    Speaking more than one language allows people to communicate with others; it teaches people about other cultures and other places- something very basic and obviously lacking in the "educator" I met in New Jersey.

    Going back to school can be an anxious time for many students. But one institution in Texas is doing its part to make sure middle schoolers are returning refreshed and inspired to learn.

    Through a process called the "bathroom inspiration project," teachers and administrators at Warren Middle School, spent their summer beautifying the school's restrooms by painting motivational murals (壁画) on each of the stalls (小隔间).Forming messages like "Your mistakes don't define you" and "Scatter (撒播) kindness," the brightly colored words are exactly what a young student needs to see when having a rough day-or any school day for that matter. And now that classes are officially in session, people are already noticing a positive impact.

    Since posting photos of upgrades to the school in July, Principal Joshua Garcia says that the alterations have aroused a great response.

    "Students have been talking about the murals from the moment the pictures had been posted. Some even took the time to find a reason to come up to the campus to see the murals," he says." I think what makes this small little action so valuable is that it has set the tone for our campus."

    And not only is that important to students, parents, and fellow staff, but it is also vital for the school's new principal, who is trying to gain the trust of the community during a time in which trust is so necessary for schools.

    "Being new to the campus, I think the parents were able to see how much I value their children and have their best interest at heart," Garcia continues. "I have had many parents tell me how they can just feel a difference in the campus climate and how much they are enjoying seeing their children wanting to come here. These murals have put trust back in the campus and its teachers, and by doing so we are able to build a culture in which our students want to be here and learn."
