单选题Eli Whitney's cotton gin famously changed the face of the agricultural industry by greatly increasing productivity. Although the gin was enormously popular, Whitney himself struggled to make a profit from it. After receiving a patent for his invention, Whitney and his business partner opted to produce as many cotton gins as possible and to charge farmers a user fee instead of selling them outright. Farmers considered this fee unnecessary and exorbitant, and began manufacturing copies of the cotton gin instead. Because of a loophole in the patent law, the many lawsuits brought by Whitney and his partner against the farmers were fruitless. The duo finally agreed to license their cotton gins at a reasonable price. However, due to the costs of their legal battles, they were unable to make the fortune that Whitney had previously predicted.

单选题When I was preparing for my two-week vacation in southern Africa, I Line realized that the continent would be like nothing I had ever seen. I wanted to explore the urban streets as well as the savannah; it's always been my goal to have experiences on vacation that most other tourists fail to find. When my plans (5) were finalized, I left for Africa. The cultural differences were stunning, and made for plenty of laughter and confusion, but always ended up bringing smiles to our faces. What's funny now, though, more than ever, is how ridiculous I must have seemed to the people of one village when I played with their dog. Apparently, the role of dogs in America is nothing like it is in the third world. (10) When I walk the streets of my hometown now, I often find myself staring at all of the dogs and dog owners on the sidewalk. The way I see it, the American dog lives for the thrill: a hug, a scratch behind the ears, a new chew toy, another chance to fight against the leash it knows is only six feet long. Dog owners love to believe their animal is smart, while people who've never owned a dog tend to (15) believe the opposite. With a little training, the dogs don't bark, bite, or use the sofa as a toilet, but they do provide years of unconditional affection and loyalty, plus the occasional lame-brained escapade at which human onlookers can laugh. I am convinced African dogs could clobber their American counterparts. The relationship between a typical African and his dog is one of tangible mutualism. (20) I say tangible because the African sees himself as the dominant creature not to be bothered by the dog, but nevertheless responsible for providing for it. Hence, no attempts at behavioral training are ever made on African dogs. Instead, the African seizes power with a chunk of scrap meat and a bowl of water. The dog soon learns to quit yapping and biting at the hand that feeds him. Never does (25) the African speak to the animal. I'm not even sure such dogs get names. Their behavior becomes interestingly balanced, however, much to the surprise of the compassionate American dog lover.
