【文章內(nèi)容簡介】 D . Delighted.53. The men hunted the hare at the cost of the lives of______.A. one rider and one horseB. two riders and two horsesC. six or eight huntsmen and a dogD. the oldest horse and a huntsman54. The best title for the passage would be______.A. What a Poor Hare B. How Cruel Men AreC. My Childhood Memory D. Scenery in the Field(B)I always helped my dad DIY ever since I was young. One day my father brought me with him to change his car system. When my father and the technicians opened up the car system and took the system apart，my eyes were glued to what was inside immediately，especially the microchips(集成電路）一I was thrown by the amazing possibilities they represented. That was the moment when my passion for engineering was sparked. Ever since then I have loved to solve problems. Whether they are logical puzzles， or fixing appliances and furniture，I have always been an engineer at heart.As I progressed in high school，I was actually more exposed to the medical field. During my time working at Princess Margaret Hospital，I realized this opened my passion for chemistry. In PMH getting medicine to patients sooner，I always found smiles on their faces. I knew my future career would include helping others，as reflected in the 1000 volunteer hours I had gained during my high school years. I wasn’ t sure what I had wanted to be，but I knew what I had wanted to do。 I wanted to aid people using my knowledge of the sciences，especially chemistry and physics.I had loved learning physics for as long as I could remember. Having a job，volunteering regularly， and being an active badminton player，during the last year of high school made it a little tough but worth it. With the skiils I learned about how to solve problems in physics，I wiil e out of high school not only with experiences that taught me to be a hardworker ，but also with teamwork，perseverance and a passion for problem solving that wiil aid my future career as an engineer.To achieve my goal ，I need to be equipped with the best knowledge and experience. Of course University of Toronto is the ideal place for me to develop that knowledge and realize my dream.55. The author intends to tell us in the first paragraph______.A. his father was a famous engineerB. his father made a great success in lifeC. how his father was strict with him in studiesD. how his idea of future career was developed.56. Which words can describe the author39。 s high school life best?A. decent and fortable B. hard but fulfiilingC. relaxing and colorful D. lonely but efficient57. The author claims that he will surely be ______in the future.A. a chemical engineer B. a physical engineerC. a petent engineer D. a scientific researcher58. We can infer from the passage that the author wrote the passage .A. before his high school graduation B. in University of TorontoC. after he became famous D. before his job interview(C)Precision(精準(zhǔn)）agriculture is a way of thinking about how to improve production and get more from existing resources. It often involves the use of technology. An example found mostly in wealthier countries is a puterguided tractor. The puter does most of the driving. It uses signals from satellites in the Global Positioning(定位）System. GPS technology helps the tractor cut rows in straight lines and put the right amount of fertilizer in the right place.Jimmy Messick is a farmer in northern Virginia，not far from Washington. He says the GPS guidance system makes it easy to e back later and plant the seed in his fields of corn. Because of the GPS guidance ，Messick now pays half what he once did for fertilizer. Raj Khosla is an agronomist (霧）at Purdue University in Indiana. He says saving even a liitle bit of seed，pesticide or fertilizer “l(fā)eads directly to expense savings and less environmental damage. ”Farmers in the developing world can use precision agriculture even without hightech tractors. “We do not necessarily have to have plex，large machines to practice what could be done as simply as using bottle caps，’’ Mr. Khosla says. The idea is to use a bottle cap to pour a measured amount of fertilizer right next to each plant. It takes more work than simply throwing handfuls of fertilizer across a field. But Mr. Khosla says when researchers taught this bottle cap method to farmers in subSaharan Africa， they discovered that it was worth the extra effort if they could only afford a small amount of fertilizer. “There was a huge difference: more than double，in terms of productivity. ’，.Of course，new technology is not always so cheap. But Mr. Khosla says farmers could form a cooperative or bine their resources to pay for new equipment. He and other researchers worked with a farmer in India to precisionlevel(平整）his wheat fields. That kept the fields from developing wet and dry areas that reduced productivity. The farmer also added better fertilizers and insect control. As a result ，he was able to grow almost three times as much wheat on the same amount of land. Mr. Khosla says with the extra money the farm
