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 Mom 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 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 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, hang on, and finally transcend 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. I prayed to be a balloon.

    The next time someone asks you where the biggest ocean is, point them toward Jupiter. While earth harbours about 320 million cubic miles(1,333 cubic km)of water, our planet is practically a desert compared to the rest of the Solar System.

    A moon of Jupiter called Europa, for example, which is roughly the size of our own Moon, likely hides a subsurface ocean with more than twice as much water as there is on Earth.

    Yet even that pales into insignificance in comparison to Europa's neighbour Ganymede; more than 30 times as much water as our home planet is thought to reside there as liquid and ice.

    And scientists keep finding more water wherever they look. On September 28, researchers reported that Dione — a small moon of Saturn — probably has a subsurface ocean, too.

    To see just how Earth stacks up against other ocean worlds, Business Insider contacted Steve Vance, a planetary scientist at NASA's Jet Propulsion Laboratory who's calculated the numbers on just how much water might be out there.

    In order of how much water they have, from the least to the most, they are: Enceladus, Dione, Earth, Europa, Pluto, Triton, Callisto, Titan, and Ganymede. Mimas, a moon of Saturn, and Ceres, the largest asteroid in the Solar System, are also thought to have subsurface oceans —but scientists aren't yet sure how big each one might be.

    In today's Internet age, the demand for online games continues to grow. Online computer game centers exist in many cities and towns throughout Asia. Facing the pressures of school and life, people tend to the virtual（虚拟的）world, expecting a diversion from these problems. Too often, however, they can lead to problems and unhealthy addictions.

    This is most clearly seen in the example of South Korea. The country has the world's highest percentage of high-speed Internet services. It also has a high number of online game players and related problems. In 2002, a young man collapsed(突然晕倒) and died while playing online games. He had been playing almost non-stop for 86 hours at an Internet café. Another young man killed his sister after becoming confused between the online world and real life. A 12-year-old boy stole US $ 16,000 from his father and ran away from home. He did this to continue his obsession(着迷) with an online game. Such problems, however, don't just happen in South Korea. They are spreading to other parts of Asia as well.

    What kinds of people develop online game addiction? What does the problem look like? Dr. SueHuei Chen, a clinical psychologist, researches Internet addiction. She discovered some signs of at-risk individuals such as lack friendships and good social skills. Those problem individuals feel it so compulsive（强迫的）to play online games that they could sacrifice things such as school or family. They feel the need to spend more and more time online. And they become upset if anyone tries to limit their online game playing.

    How many problem game players are there? In mainland China, the potential number of problem online gamers is alarming. In 2004, the China daily reported that China had 13.8 million online game players. Besides, it stated that 80 percent of these were under 25 and had signs of addiction. Such numbers point toward a growing problem among Chinese youth.

    Make sure to keep control over your online game playing. If you don't control it, it can get control of you.

    Three important changes that will affect people's everyday life in the future.

    The cashless society

    Cash and bank notes will disappear almost completely. They will be replaced by smart cards with microchip (微芯片) "loaded" with some money. When we pay for goods, we will put our smart cards into a payment terminal (终端) and money will be transferred (转) from our cards to the retailer's (零售商的) card. When all the money is used up, we will be able to "reload" it by inserting it into a telephone, dialing our bank account and putting money to the card from the account. If we want to transfer money from our cards to a bank account, we will use the same method. Smart cards will be able to hold several different currencies at the same time. So if we go abroad, we will be able to use our smart cards in the same way.

    Interactive telephones

    Human telephones will be replaced by talking computers. These computers will recognize speech, ask us what information we need, find the information and change it to speech. If we want to book a flight or pay a bill by phone, we will ask a talking computer to do it. Of course, this won't happen until all the technology is in place, but when it is we will soon get used to using computers in this way.

    ________________

    Traffic congestion (拥挤) in cities will be reduced because drivers will use electronic maps to find the quickest way to their destinations and avoid traffic jams. Because people have to pay to drive in cities, they will stop using their cars and use public transport instead. Speed control systems will be built into cars. These systems will control the speed of the car according to the traffic and weather conditions and prevent accidents.

Tips for Writing Short Stories

    I was reading an article with David Vann's top tips for writing short stories -- he is a published writer, his most famous book being, "Legends of a Suicide." First of all he stats that there are no rules, but if he were forced to create rules for short stores, then they would be something like the following.

    He says there is no room for anything that is not related to the protagonist -- the main character of the story -- or indeed the problem of the protagonist. He makes it clear that the protagonist must have a problem, and this problem must divide the protagonist: he doesn't know what he is going to do to solve the problem. There is no point, then, in having a short story about a man who says he is hungry and then just goes to the shops to buy food. Nothing exciting happens. But if the man is hungry and he has a child who is hungry, then he has a problem; who does he give the food to?

    There should also be an antagonist, that is, somebody who works against the protagonist. The antagonist should ideally have the same problem as the protagonist but will have a totally different way of looking at it. This presents the possibility of having battles in the short story.

    Furthermore, the antagonist and the protagonist must know each other. But because they are viewing the same problem from different angles, they will probably drive each other crazy.

    Finally, the short story has to acknowledge a change in the protagonist. We must then, as a reader, see how the character will continue their life differently as a result of the events of the story. There is no point in going back to the beginning; the short story is a waste of time if nothing actually happens that is significant.

    It is very hard to create a character whom a reader cares about and a plot that a reader is interested in with just a few hundred words. But it is possible: Edgar Allen Poe, Anton Chekhov, and JG Ballard -- amongst many others -- have proved repeatedly that short stores can be little pieces of perfection. The best don't just see the protagonist change; they see the reader change, too.

Civilization began with agriculture, and though humanity has changed significantly, agriculture remains very important. In certain countries, its significance is more apparent, but the reality is that every country in the world depends on agriculture for one thing or another.

It provides employment. Whether it's working as a farmer, a harvester, a technician for farm equipment or a scientist, there are plenty of jobs available in this field. In developing countries, agricultural jobs help reduce high rates of unemployment.

It's crucial to a country's development. Economic development is tied to a country's agricultural sector. When trade, national avenue, and employment are combined in a positive way, a country enjoys reduced poverty and boosted economic growth. Because strong agriculture results in benefits fairly quickly, focusing on it is one of the best ways to speed up development and improve a country's standing across the globe.

It drives innovation in technology. Because healthy agriculture is so essential to a country's well-being, it's been the setting of some of the most exciting innovations in technology. Through artificial intelligence, blockchain software, and more, scientists and farmers have been figuring out ways to increase crop productivity, use less water, and reduce negative impacts on the environment. For scientists and tech companies, agribusiness is one of the most fascinating and productive fields to work in.

It's the source of our food supply. Arguably, the most important aspect of agriculture is that it's the source of the world's food supply. No matter where or what you are eating, the ingredients in your meals come from somewhere. All roads lead to agriculture. In countries dealing with food insecurity and severe malnutrition, their agricultural sectors are suffering. When agriculture thrives(蓬勃发展), fewer people go hungry.

It can help heal the environment. Agriculture possesses the power to cause harm or heal. When farmers prioritize biodiversity on their land, it benefits the earth. Having more biodiversity results in healthier soil, better water conservation, and healthier pollinators(传粉者).

All in all, agriculture plays a critical role in the entire life of a given economy. Agriculture culture is the backbone of the economic system of a given country.
