Making a good job choice is almost as good as choosing a good life. So, choosing a job is one of the most important decisions to make in life.

    For my job, there are three important things that I will consider: The first one—that I must work in an area I like—is most important to me. Someone once said if you find a job that you enjoy, then you won't have to work another day. I would like to work in an area where I can be more creative. I would like to be the most valuable member there. All this is possible only if I like what I do.

    The second one is that the area of my work must lead me to solve some new and hard problems. I would like to stay in the same area for a long time. In order for this to happen, the work must provide enough problems. More than just working to live, I enjoy making a difference and trying my best for the whole progress. I would also like to be well remunerated for my hard work, so I can lead a comfortable life with this hard-won money. Then I can provide the best for my family.

    The third important thing is that I would like to work in an area that would help other people. The work in my mind is in fields such as the army, training or management. In such areas, I can help to develop the abilities of others and bring out their best. It would be a most satisfying job to help young people to become the best that they can be. When I become old, I would like to look back with a great sense of satisfaction that thousands of people have become better persons through my work.

    I accept the idea that no one should make a choice of a job suddenly or quickly. He should decide what he wants to be in the long run. Then, he should decide how he works towards it. He should study the proper courses, read the books and speak to knowledgeable persons in that field before making a job choice. A good choice will most probably lead to a better life.

    Each time I see a balloon , my mind flies back to a memory when I was a six-year-old girl . It was a rainy Sunday and my father had recently died . I asked my mum if my 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 . “ Can the mailman go there ? ” I asked .

    “ No , but I have an idea . ” Mum drove to a party store and returned with a red balloon . I asked her what it was for . “ Just wait , honey . You'll see . ” Mum 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 Mum 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 Mum . She read it over , and a smile crossed her face . She made a hole in the corner of the letter to tie it to the balloon . We went outside and she gave me the balloon . It was still raining . “ Okay , on the count of three , let it go . One , two , three . ” The balloon , carrying my letter , flew upwards 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 keep on , fly up , and finally go beyond this cold world and his sick body . He rose into sky and became something beautiful . I watched until the balloon disappeared into the grey and white and I prayed that his strength was passed on . I prayed to be a balloon .

    Although his 1-year-old smart-phone still works perfectly, Li Jijia already feels the need to replace it.

    “There are many better ones available now. It's time to upgrade(更新）my phone.”

    Li's impatience is shared by many. Shortly after the season when new products are released（发布，发售）, many consumers feel the urge to upgrade their electronic equipment, even though the ones they have still work just fine.

    As consumers' minds are occupied by Apple's newly released products and debate whether the Google tablet is better than the new Amazon Kindle, it might be time to take a step back and ask: “Do we really need the latest upgrades?”

    According to Donald Norman, an American author, “planned obsolescence (淘汰）” is the trick behind the upgrading culture of today's consumer electronics industry.

    Electronics producers strategically release new upgrades periodically, both for hardware and software, so that customers on every level feel the need to buy the newest version.

“This is an old-time trick—they're not inventing anything new,” Norman said. “This is a wasteful system through which companies--many of them producing personal electronics-- release poor-quality products simply because they know that, in six months or a year, they'll put out a new one.”

    But the new psychology of consumers is part of this system, as Norman admitted, “We now want something new, something pretty, the next shiny thing.” In its most recent year, Apple's profit margin(利润) was more than 21 percent. At Hewlett-Packard, the world's biggest PC maker, it was only 7 percent.

    Apple's annual upgrades of its products create sales of millions of units as owners of one year's MacBook or iPhone line up to buy the newest version, even when the changes are slight.

    As to Li Jijia, the need for upgrading his smart-phone comes mainly from friends and classmates. When they are switching to the latest equipment, he worries about feeling left out.

    “Some games require better hardware to run,” said Li. “If you don't join in, you lose part of the connection to your friends.”

    The quick action of Nick helped five people escape a fire on Hope Road. Nick said he usually left his house about 5:30 a.m. to do morning exercises, but that day he decided to stay at home to get his daughter ready for school. As he looked at his neighbor's house, he realized that it was on fire. "I saw smoke and flames and ran over and started beating on the side of the house shouting, 'Your house is on fire! Your house is on fire!'" Nick remembered it was at about 9 a.m. that the firefighters put out the fire.

    Beverly Penny and her husband, Clark, along with their younger daughters, were sleeping in the living room, next to the kitchen, when they heard Nick beating on the walls. She opened the bedroom door and black smoke came in. She managed to get her kids out. Her dog tried to hide under the bed, but Penny caught it by the leg and threw it out of the door. However, chickens in one of the rooms weren't so lucky.

    Firefighters got the call at about 7:05 a.m. "When we arrived with our fire trucks, there were heavy flames outside on the house," Jerry said. He called Nick a hero, saying that without his quick responses(回应) the result could have been much worse. "The firefighters were fast," Nick said. "They arrived here within about three minutes."

    "They did a great job, and I can't thank them enough," Penny said, then looked at what remained in the house and shook her head as tears rolled down in her eyes. "Everything I have is gone. Luckily nobody was hurt in the fire." She said the fire could have been caused by an electrical problem. "We've been having problems with mice, so that we could have had something to do with it," she added.

    When you think of batteries, you'll likely think about them powering up remote controls, cellphones, flashlights and toys. But some people carry a battery around in their body to power a pacemaker (起搏器). It isn't really pleasant and easy to carry batteries because they need to be replaced so often and they can leak poisonous chemicals. A battery-powered pacemaker may become a thing of the past, thanks to a new technology developed by UCLA researchers: A biological super capacitor (超级电容器) , which is thinner than several hairs.

    Teams of researchers at UCLA and the University of Connecticut published a paper in a journal explaining their new invention. The super capacitor is made from a carbon material, and coated with human-like proteins that act as electrodes (电极). But what makes the device different is that it is powered by an energy harvester that changes body heat and movement in the blood into energy.

    Those traditional pacemakers are six to eight millimeters(毫米) thick. They are much bigger. The new super capacitor, which, due to its lack of battery, is only one micrometer(微米) thick. This "little" feature could benefit the new pacemaker's energy efficiency, researchers stated. Also, unlike other batteries used in medical treatments, the super capacitor can bend and twist in the body without suffering damage.

    Though they've not been widely used in the medical world, super capacitors have the ability to serve as a safer and more efficient medical device than the traditional battery-operated devices, the researchers believe.

    "In order to be effective, battery free pacemakers must have super capacitors that can get, store and transport energy. However, commercial super capacitors are too slow to make them work", said Maher El-Kady, a UCLA researcher and co-author of the study. “Our research focused on the custom-designed super capacitor to capture energy effectively, and finding a way to make it exist together successfully with the human body."

    Bottled water is a booming industry in New Zealand, but it's terrible for the environment —each bottle thrown away adding to the 190,000 tons of plastic New Zealanders throw into landfills each year.

    But now one company has created water storage that they hope will prove to be just as convenient as a plastic bottle—but contains no actual plastic.

    Skipping Rock Labs make Oohos, flexible membranes filled with water that are constructed using a seaweed extract—meaning they, re totally edible and biodegradable, wrapping and all.

    There aren't any known side effects from digesting the membranes, which are tasteless—though Ooho! says flavors can be added to make them more appetizing.

    The company took to crowdfunding site CrowdCube with the idea, and it has since gone viral— with more than 900 investors bagging them A£ 751,700 to develop and launch the Ooho! balls ( $ 1.35 million).

    Skipping Rock Labs create the balls by dipping ice into brown algae and calcium chloride, with the membrane taking shape around the ice—and while that may sound complicated, the company says it, s more cost-effective than producing a plastic bottle.

    A layer atop the membrane can be peeled off just before drinking, for hygiene purposes. Skipping Rock Labs are hoping their new product takes off—and that it starts to put a dent into the plastic packaging industry.
