what is my favorite invention?
we knew there had been many inventions at the last century, for example,electric light bulb, telephone, phonograph, mimeograph machine, automobile,airplane, atomic weapon, computer and so on. what is my favorite invention?
personally, my favorite invention should be computer. in the old days, manyscientists took much time to calculate and deal with research data, so theeffective time in doing research was relatively shortened. for millions of timesof calculating per second by computer, the researchers may have enough time tostudy more important issues. the processing of experiment results became verysimple and easy. aren’t those all evidences that the computer is one of thegreatest inventions in the last century, are those?
so my favorite invention is computer.

Ladies and gentlemen , good afternoon! i’m very glad to stand here and give you a short speech. today my topic is “youth”. i hope you will like it , and found the importance in your youth so that more cherish it.
first i want to ask you some questions:
1、do you know what is youth?
2、how do you master your youth?
youth is not a time of life, it is a state of mind ; it is not rosy cheeks , red lips and supple knees, it is a matter of the emotions : it is the freshness ; it is the freshness of the deep springs of life .
youth means a temperamental predominance of courage over timidity of the appetite , for adventure over the love of ease. this often exists in a man of 60 more than a boy of 20 . nobody grows old merely by a number of years . we grow old by deserting our ideals.
years wrinkle the skin , but to give up enthusiasm wrinkles the soul . worry , fear , self –distrust bows the heart and turns the spirit back to dust .
whether 60 of 16 , there is in every human being ‘s heart the lure of wonders, the unfailing childlike appetite of what’s next and the joy of the game of living . in the center of your heart and my heart there’s a wireless station : so long as it receives messages of beauty , hope ,cheer, courage and power from men and from the infinite, so long as you are young .

Computers play an important role in the modern world. Today they are used in many areas of human activities, such as business, industry, science and education. I'm a primary school student. I always search for information on my PC, make PPT or type article with word software and sometimes listen to music, play games on the computer in the weekends. Sometimes I write e-mails to my friends on the computer, too. I often chat with people on-line. I usually do my homework on the computer, too, it's very easy.
I also enjoying watching cartoons on-line, because I can find my favorite cartoons easily, when I watching TV, I should wait the advertisement and watch the cartoons on time. But in computer, I can watch my favorite cartoons any time, and needn't wait for advertisements.I seldom buy things on the computer, because I don't know it. I sometimes go to the forums on the weekends, there are many people, and it's very interesting.
How about you, my friend?

If you're middle-aged and your memory's not what it used to be, check thebathroom scale, researchers warned, suggesting overweight people tend to scoremore poorly on tests of memory than their thinner peers do.
The findings suggest that a heavier weight in middle age may mean a higherrisk of dementia later in life.
Reporting in the journal Neurology, the researchers speculated that higherrates of cardiovascular disease or diabetes might help explain the link. Butit's also possible that substances produced by fat cells, such as the hormoneleptin, have direct effects on the brain.
The study compared mental abilities to body mass index (BMI), a
measurement of weight in relation to height used to define overweight andobesity. A BMI of 25 or more indicates overweight, and 30 or more is obese.
The study also investigated the relationships between BMI and cognitivefunction in 2,223 healthy men and women between the ages of 32 and 62 in Francethrough the use of four cognitive tests.
The study found a higher BMI was associated with lower cognitive test scores.Results from a test involving word memory recall show people with a BMI of 20remembered an average of nine out of 16 words, while people with a BMI of 30remembered an average of seven out of 16 words.

It was a cloudleday. The warmth of the fall sun made the day seem as if itwould be perfect. Yes, for me perhaps, but not exactly for the technician whowas working on one of my laboratory machines. The technician definitely knewwhat he was doing and seemed exceptionally qualified except for one thing. Hewas no electrician. He had found a motor that he identified as being bad. Themotor shaft was much too difficult to turn and he had indicated that this was amajor problem. "Expect two to three days for a new one to arrive," he said.
One thing my friend didn't understand is that when power is supplied to agenerator, it becomes a motor and when mechanical power is applied to a motor,it becomes a generator. During the proceof his working on the machine hedisconnected the leads to the motor and spun the shaft turning the motor into agenerator. Disconnecting the leads in effect took the load off the motor, theleads being connected causing the motor not to turn freely. He looked ratherperplexed to see the motor shaft spin so freely. For reasons unknown to me, hespun the shaft again and grabbed the wires protruding from the motor. I don'tbelieve I have ever heard quite the string of expletives that this man let flyfrom his mouth. With his eyes widened he had to slap his hand loose from thewires as the flow of generated electricity locked the grip of his hand.
Now this being funny all by itself, it evidently wasn't funny enough forthe technician because he spun the motor and grabbed the leads again. Anotherstring of expletives that have never been heard previously by man were unleashedunto the world.
Several years ago, I had heard about a man who went fishing with an oldcrank type telephone generator. He'd drop the leads into the water and crank thegenerator causing the fish to be shocked whereby they would float to the top forhim to collect. On this warm and cloudlefall day, I'd say, the technician's fishhad all floated to the top.
