Article: The man from the west stopped and drew back his arm. "You're not Jimmy Wells," he said in a quick and angry way, "Twenty years is a long time, but not long enough to change a man' nose from a Roman to pug." "It sometimes changes a good man into a bad one," said the tall man, "you've been under arrest for ten minutes. Silky Bob. prefix = st1 /Chicagothinks you may have dropped over our way and phones us she wants to have a word with you. Going quietly, are you? That's sensible. Now before we go to the station here's a note I was asked to hand you. You may read it here at the window. It's from Patrolman Wells.?" The man from the West opened the little piece of paper handed him. His hand was steady when he began to read, but it trembled a little by the time he finished. The note was rather short. Bob: I was at the right place on time. When you struck the match to light your cigar I saw it was the face wanted in Chicago. Somehow I couldn't do it myself, so I went around and got a plain clothes man to do the job.

Article: Recently I spoke to some of my students about what they wanted to do after they graduated, and what kind of job prospects they thought they had. Given that I teach students who are training to be doctors, I was surprised to find that most thought that they would not be able to get the jobs they wanted without "outside help". "What kind of help is that?" I asked, expecting them to tell me that they would need a relative or family friend to help them out. "Surgery ", one replied. I was pretty alarmed by that response. It seems that the graduates of today are increasingly willing to go under the knife to get ahead of others when it comes to getting a job. One girl told me that she was considering surgery to increase her height. "They break your legs, put in special extending screws, and slowly expand the gap between the two ends of the bone as it regrows, you can get at least 5cm taller!" At that point, I was shocked. I am short, I can't deny that, but I don't think I would put myself through months of agony just to be a few centimeters taller. I don't even bother to wear shoes with thick soles, as I'm not trying to hide the fact that I am just not tall! It seems to me that there is a trend toward wanting "perfection", and that is an ideal that just does not exist in reality. No one is born perfect, yet magazines, TV shows and movies present images of thin, tall, beautiful people as being the norm. Advertisements for slimming aids, beauty treatments and cosmetic surgery clinics fill the pages of newspapers, further creating an idea that "perfection" is a requirement, and that it must be purchased, no matter what the cost. In my opinion, skills, rather than appearance, should determine how successful a person is in his chosen career.

Article: Li Denghai, with his muddy boots and tanned face, may not look like he is one of China's famous agricultural pioneers. But the 61-year-old man from Shandong Province has made scientific breakthroughs , which made great contributions to China's food security . His main work has been in achieving the higher output of corn production. Li, who holds the world record for the highest output of summer corn, once says, "Corn has a life; it sings and dances. If you listen clearly, it can speak to you." He started his research in 1969 when he was 20 and just dropped out of a high school. He then read an article which pointed that corn output per mu in the USA was six times higher than that in China. He was shocked and set out to work on just a small piece of land _ to see if he could increase the output. He often went to the field with a flashlight late at night, if he had been away during the day. By careful nurturing he managed to double the output. Li Denghai was awarded the "China Award for Significant Contribution to the Maize Industry" in 2005, and the same year the company named after his own name came into the market on the Shenzhen Stock Exchange. Li, however, is never happier than when he is in the middle of his cornfields. "I can forget my tiredness when talking to my corns," he says.
