[EX Q]: Article: My grandfather had a small farm where he raised beef and some grain for feed. He also worked diligently as a factory laborer and country pastor. He was a good neighbor and well-respected for honoring his word. When harvest time came, he'd piece together his old one-row corn picker and oil it up for the season. All his life he worked hard, helped others, and you could count on him to keep his promises. He had promised to harvest a few ribbons of corn on a friend's farm, but after harvesting his own corn, Grandpa's little corn picker coughed and quit. It would be out of commission until a particular part could be ordered, but that would take far too long to help this year. The factory where Grandpa worked began to require overtime. In order to keep his job there he had to leave the farm before dawn and get home until well after sunset.  One autumn night, while harvest time was running out, he and his wife sat at the kitchen table and trying to figure a way out of their dilemma. "There's nothing you can do," said my grandma. "You'll just have to tell him that you can't help with the corn this year." "Well that just doesn't sit well with me," said my grandpa. "My friend is depending on me. I can't exactly let my neighbor's harvest rot in the field, can I?" "When do you think you'd have time to do it?" she asked. "With the overtime you've been working you'd be up all night." "I know of one night that I could do it!" he said, running to the bookshelf. He grabbed the Farmer's Almanac  and started flipping through the pages. "Aha! There's still one more full moon in October." They say it's called the harvest moon because it gives farmers more light and more time to collect their crops. And so a few days later, after a long shift at the factory, my grandpa made his way to the field where my grandma met him in the truck with dinner. The weather was cold but clear, and the moon was brilliant. He worked through the night to keep his word. I know this story well, so sometimes, when I'm tempted to cut corners  or to put off responsibilities, I think of my grandfather with his scythe  cutting wide arcs of corn in the light of the harvest moon.

[EX Q]: Article: Many years ago, when I was fresh out of school and working in Denver, I was driving to my parents' home in Missouri for Christmas. I stopped at a gas station about 50 miles from Oklahoma City, where I was planning to stop and visit a friend. While I was standing in line at the cash register , I said hello to an older couple who were also paying for gas. I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend's We chatted on the way into the city, and when I got out of the car, the husband gave me his business card. I wrote him and his wife a thank-you note for helping me. Soon afterward, I received a Christmas present from them. Their note that came with it said that helping me had made their holidays meaningful. Years later, I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car and found that I'd left the lights on all day, and the battery was dead. Then I noticed that the Friendly Ford dealership - a shop selling cars - was right next door. I walked over and found two salesmen in the showroom. "Just how friendly is Friendly Ford?" I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment, so when I got home, I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you, and it meant a lot, he said. "Thank you" - two powerful words. They're easy to say and mean so much.

[EX Q]: Article: The interview had been going on for about 20 minutes and everything seems to be going well. Then,suddenly,the interviewer asks an unexpected question,"Which is more important,law or Dove?" Job applicants in the West increasingly find themselves asked strange questions like this. And the signs are that this is beginning to happen in China. Employers want people skilled,enthusiastic and devoted. So these are the qualities that any reasonably intelligent job applicants will try to show no matter what his or her actual feelings are. In response,employers are increasingly using questions which try and show the applicant's true personality. The question in the first paragraph comes from a test called the Keirsey Personality Sorter. It is an attempt to discover how people solve problems,rather than what they know. This is often called an aptitude test  . According to Mark Baldwin, many job applicants in China are finding this type of questions difficult. When a Chinese person fills out an aptitude test, he or she will think there is a right answer and they may fail because they try to guess what the examiner wants to see. This is sometimes called the prisoner's dilemma. Applicants are trying to act cleverly in their own interest. But they fail because they don't understand what the interviewer is looking for. Remember that in an aptitude test,the correct answer is always the honest answer.
