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.

    The introduction of the iPad,with its touch screen technology,has allowed even very young children to take advantage of a computer.So what if all children in a school were given an iPad to use in class and take home with them?

    Anne Laure Bazin works in a school where every child,teacher and teaching assistant is given a free iPad to use in and out of lessons.For her,the main advantage of everyone having an iPad had been the improvement in communication.Documents can be emailed straight over to workmates during a meeting.Children submit their homework by email,or through the school's learning environment.Teachers now take the register（点名）using their iPad,which means that there is a record of which children are in school,and which classroom they are in.

    The use of iPad has encouraged greater sharing of resources among teacher.All communication with parents is now done by email.Working as a group in class is much easier as children can share documents.The whole class can look at one child's work by attaching（连接）the iPad to the whiteboard.If a child has forgotten the textbook,the teacher can take a photograph of the relevant（相关的）page and send it to the student in class.

    While the use of the iPad in schools has revolutionized（变革）the way children are taught ,it hasn't completely replaced more traditional methods of teaching .Worksheets are still used in class as some children prefer the contact with paper.The children all have a textbook and exercise books.In Anne Laure's school,parents feared that the iPads would replace exercise books and children would lose handwriting skills.Anne Laure says,” The teacher are not ready to let go of the traditional style of teaching.We have welcomed the iPads in so much as they help communication and widen the resources available but we are not ready to let go of paper yet.The children themselves still value their exercise books and depend on them for review.”

    A Russian spacecraft traveling to the International Space Station Thursday had to make an emergency landing when a rocket engine failed to fire. It was the latest in a recent series of failures for the Russian space program, which is also used by the U.S. to carry its astronauts to the station.

    United States astronaut Nick Hague and Russian astronaut Alexei Ovchinin landed safely about 20 kilometers from Dzhezkazgan in Kazakhstan. The city is about 450 kilometers from the Russia's Baikonur space center, which Russia operates through an agreement with the Republic of Kazakhstan.

    Both the U.S. space agency NASA and Russia's Roscosmos reported that the two were quickly recovered from the landing area by rescue crews. A spokesman for Russian President Vladimir Putin said, "Thank God the crew is alive" after they had landed safely.

    About two minutes after launching, the three-stage Soyuz booster rocket suffered an unspecified failure of its second stage. Russia's TASS news agency said the capsule carrying the two men separated from the troubled rocket safely. This caused the capsule to drop very sharply into the Earth's atmosphere. Parachutes（降落伞）helped slow the returning capsule. Search and rescue teams were sent to recover the crew.

    Russia's RIA news agency reported that Russia has immediately put off all manned space launches after the failure. Roscosmos head Dmitry Rogozin said he had ordered a state commission to carry out an investigation into what went wrong. He said Russia will share all relevant information with the U.S.

    The TASS news agency said that the ISS crew has enough supplies and that the failed launch will not affect operations.

    The U.S. and other nations have depended on Russia to carry astronauts to the ISS since the retirement of the Space Shuttle program in 2011. In coming years, American aerospace companies SpaceX, with its Dragon 2, and Boeing, with its Starliner, are expected to return to space.

In recent years, labels have increasingly been used by the food industry. Whether "non-GMO（转基因）"or"zero trans fat","no added hormones" or"sugar-free", consumers are demanding more information about what's in their food.

A report by Nielsen found that 39 percent of consumers would switch from the brands they currently buy to others that provide clearer, more accurate product information. Food manufacturers are using the new labels to meet consumers' demand, with an eye towards giving their products a leg up over the competition, and their bottom lines a boost as well.

On its face, the new marketing strategy makes sense. But these so-called "absence claims" labels are harmful both to the consumers who purchase the products and the industry that supplies them. For example, Hunt's put a "non-GMO" label on its tomatoes a few years ago — despite the fact that, at the time, there was no such thing as a GMO tomato on the market. Over the long term, this strategy will have the opposite effect: by creating fear, we run the risk of damaging consumers' trust.

Eventually, it becomes a question in consumers' minds: Should I have ever been eating these foods in the first place? By purchasing and consuming these types of products, have I already done some kind of harm to me?

For food manufacturers, it will damage consumers' trust, which in turn would lower sales for the whole food industry. And this isn't just supposition. A recent study by a group of academics at the University of Delaware found that "absence claims" labels can stigmatize(污名化)food produced with conventional processes even when there is no scientific evidence that they cause harm.

In addition to the likely negative long-term impact on sales, it sends a message that innovations in farming and food processing are unwelcome, eventually leading to less efficiency, fewer choices for consumers, and, ultimately, more costly food products. Therefore, it's clear that food manufacturers must be careful when using "absence claims" as a marketing strategy. If we allow this kind of label fear-mongering to continue, the losers will be all of us.

Sargassum is the smelly seaweed piling up on beaches across the Caribbean. It isn't something most people 1 kindly. But for Omar de Vazquez, a gardener, it was something like a(an) 2 .

Years ago, as part of his gardening business, Omar launched a beach cleanup service to 3 the leafy seaweed. But, as its 4 intensified, he started considering how to turn it into something useful, and in 2018 he 5 a way to use it in building blocks. He started his company—SargaBlock to market the bricks which are being 6 by the United Nations Development Program (UNDP) as a sustainable solution to a current environmental problem.

"When I look at SargaBlock, it's like looking in a 7 ," he says, comparing his company to overcoming his personal 8 , including drug and alcohol addiction. "That was a time when I felt unwanted and 9 , like the sargassum people complained about."

Luckily, Omar grew up in nature and poverty, which 10 his character and turned him into someone who takes action. He wanted to make something good out of something everyone saw as bad. Omar then put his idea into 11 , mixing 40% sargassum with other organic materials, like clay, which he then puts into a block-forming machine. The process was 12 .

The UNDP selected Omar's work for their Accelerator Lab, which 13 and recognizes innovative solutions to environmental challenges globally. The idea is that some of the most timely and creative 14 come from locals suffering from environmental dilemmas 15 .

Emily, a 14-year-old teenager, walked through her town one afternoon. Her eyes were drawn to the sight of people without homes on street corners, trembling（颤抖） against the chill. It was a scene that stirred something deep within her—a desire to make a difference, no matter how small.

Emily decided to turn her love of baking into a force for good. She whipped（搅打） cream, mixed flour, and baked cookies and cakes in her family kitchen. With the support of her friends and family, she set up a colorful stall in her bustling neighborhood, offering her homemade treats to passersby in exchange for donations.

The response was overwhelming. People were not only touched by Emily's handmade cookies but also inspired by her spirit. Before long, donations were pouring in. In just a few short weeks, Emily had raised over $1,000—a symbol of one's kindness to ignite a community's generosity.

But Emily's heart was set on doing even more. Inspired by the success of her bake sale, she came up with the idea of organizing a charity run. A community-wide event that would bring people together in support of a common cause. She reached out to local businesses and called for volunteers to help her realize the project. On the day of the charity run, participants ran under the clear, open sky, and the running campaign raised over $5,000 for the local homeless shelter.

For Emily, the true reward lay not in the dollars raised or the miles run but in the knowledge that she had touched the hearts of her community and shown that even the smallest act of kindness can make a difference to the world.
