Have you ever used a typewriter? If not, you've surely seen one. This useful machine has a most interesting history.

　　Although you may think that the typewriter is a modern invention, the idea goes as far back as the early 1700s. It was then, in 1714, that England's Queen Anne granted Henry Mill the first patent（专利）for a machine that typed letters. Called An Artificial Machine or Method For Impressing Letters, the machine remained just a design on paper.

　　Various other typing machines were invented over the next hundred years or so. However, all of them had the same problem: they required more time to use than writing the same material by hand. Things improved a little around 1829 when an American named William Burt invented a machine called the desired letter. He also pressed a bar to link the paper. The machine printed letters well, but it had a top speed of only five words a minute.

　　Finally, in 1874, a more practical machine was introduced to the public. Invented by an American Christopher $holes and some of his companions, the machine was set up by E. Remington and Sons and called the“Remington Model No.1”. It was the first typewriter to have the kind of typewriter keyboard we know today.

　　You may have a look at the typewriter keyboard and wonder about the strange arrangement of letters. The arrangement, strangely enough, has nothing to do with making typing easier or faster. As a matter of fact, the keys were so arranged to force typists to type lower. Typing too fast caught the keys of Remington 1 pressed together. They still follow this early arrangement of letters of the keyboard.

Parents who feel disappointed at their teenagers’ failure to pay attention in class, and inability to sit quietly long enough to finish homework or plan ahead, should take solace. Their children are not being lazy or careless, according to new research.
The research has found that teenagers’ brains continue developing far longer into adulthood than we used to think. Teens may look like young adults but their brain structure is similar to that of much younger children.
“It is not always easy for teens to pay attention in class without letting their minds wander, or to ignore distractions from their younger brothers or sisters when trying to solve a maths   problem,” said Dr Iroise Dumon-theil. “But it’s not the fault of teenagers that they can’t pay attention and are easily distracted. It’s to do with the structure of their brains. Teens simply can’t think as well as an adult.”
The research showed that the brain of a teenager works less effectively than that of an adult. “We knew that the front of the brain of teens functioned in a chaotic  (混乱的) way but we  didn’ t realize it continued until the late 20s or early 30s,” said Dr Sarah-Jayne Blakemore, who led the research.
Chaotic thought patterns are a result of teenagers’ brains containing too much grey matter — the cell bodies and connections which carry messages within the brain. As we age, the amount of grey matter in our brain reduces.
“What our research has shown is that there is simply too much going on in the brains of teens,” said Blakemore. “The result is that their brain energy and resources are wasted and their decision-making process is badly influenced. Adults, on the other hand, have less grey matter. This means that the brain works far more effectively.”

I was loading (装载) my truck to go to the market when I hurt my left eye. The pain was like a hot sword(剑) being shoved through my head. I fell down on my hands and knees, and I knew it was bad.
I was taken to the Erlanger Hospital in Chattanooga, and the doctors operated on me several times but couldn’t save my left eye. When they told me the news, I wanted to die.
Even after I got my fake（假的） eye, I couldn’t shake the sadness. To make matters worse, I lost my job as a transportation officer because of my lost eye. But one morning, I woke up and the TV was on, and there was a 16-year-old girl who had been badly burned on her face and legs. Her situation was much worse than mine. She wore a big smile and seemed to look right at me and said, “You can’t ever give up.” At that moment, I thought, “This is just an eye. Get over it.” And I did.
It’s been almost 12 years since my accident, and there’s nothing I can’t do now that I used to do. And although I didn’t get my old job back, I got my license again.
I read a story once. In that story, a man was feeling bad because he had no shoes until he met a man who had no feet. No matter how terrible your problem is, remember there’s always someone somewhere who’s worse off. So cheer up and smile at life!
