材料一:古人所谓意象,尽管有种种不同的用法,但有一点是共同的,就是必须呈现为象。
那种纯概念的说理,直抒胸臆的抒情,都不能构成意象。
因此可以说,意象赖以存在的要素是象,是物象。
物象是客观的,它不依赖人的存在而存在,也不因人的喜怒哀乐而发生变化。
但是物象一旦进入诗人的构思,就带上了诗人主观的色彩。
这时它要受到两方面的加工:一方面,经过诗人审美经验的淘洗与筛选,以符合诗人的美学理想和美学趣味;另一方面,又经过诗人思想感情的化合与点染,渗入诗人的人格和情趣。
经过这两方面加工的物象进入诗中就是意象。
一个物象可以构成意趣各不相同的许多意象。
由“云”所构成的意象,例如“孤云”,带着贫士幽人的孤高。
陶渊明《咏贫士》:“万族各有托,孤云独无依。
”杜甫《幽人》:“孤云亦群游,神物有所归。
”“暖云”则是带着春天的感受。
罗隐《寄渭北徐从事》:“暖云慵堕柳垂条,骢马徐郎过渭桥。
”“停云”却带着对亲友的思念。
陶渊明《停云》:“霭霭停云,蒙蒙时雨,八表同昏,平路伊阻。
”辛弃疾《贺新郎》:“一尊搔首东窗里,想渊明《停云》诗就,此时风味。
”……同一个物象,由于融入的情意不同,所构成的意象也就大异其趣。
诗人在构成意象时,可以夸张物象某一方面的特点,以加强诗的艺术效果,如“白发三千丈”“黄河之水天上来”;也可以将另一物象的特点移到这一物象上来,如“我寄愁心与明月,随君直到夜郎西”“丛菊两开他日泪,孤舟一系故园心”“长有归心悬马首,可堪无寐枕蛩声”。
这些诗都写到“心”,心本来不能离开身体,但李白的“愁心”却托给了明月,杜甫的“故园心”却系在了孤舟上,秦韬玉的归心则悬在了马首上。
这些意象都具有了“心”原来并不具备的性质。
诗人在构成意象时,还可以某一物象为联想的起点,创造出世界上根本不存在的东西。

And chances are that you‘ll have traveled through a wind shield (挡风玻璃)or door to do it. Studies show that chances of dying after a car accident are twenty-five times greater in cases where people are ―thrown clear".Myth Number Two: Safety belts ―trap‖ people in cars that are burning or sinking in water.Truth: Sorry again, but studies show that people knocked unconscious(昏迷)due to not wearing safety belts have a greater chance of dying in these accidents. People wearing safety belts are usually protected to the point of having a clear head to free themselves from such dangerous situations, not to be trapped in them.Myth Number Three: Safety belts aren‘t needed at speeds of less than 30 miles per hour.Truth: When two cars traveling at 30 mph hit each other, an unbelted driver would meet the windshield with a force equal to diving headfirst into the ground from a height of 10 meters.61.

Even if a student is not performing well, they can predict success. We are convinced that this ability, this gift, is evidence that they were ―called to teach.‖ If the gift of sight is evidence, how greater must be the gift of touch. I have a story.I grew up in the fifties in a poor African American neighborhood in Stockton, California, that had neither sidewalks nor an elementary school. Each day, always in groups at our parents‘ insistence, my friends and I would leave home early enough to walk eight blocks to school and be in our seats when the bell rang. For four blocks, we walked on dusty roads. By the fifth block, we walked on sidewalks that led to lovely homes and to Fair Oaks Elementary School. It was at Fair Oaks, in a sixth grade English class, that I met Ms. Victoria Hunter, a teacher who had a huge influence on my life.During reading periods, she would walk around the room, stop at our desks, stand over us for a second or two, and then touch us. Without saying anything to us (nothing could break the silence of reading periods), she would place two fingers lightly on our throats and hold them there for seconds. I learned many years later when I was a student at Stanford University that teachers touch the throat of students to check for sub-vocalization (默读), which slows down the reading speed. I did not know at the time why Ms. Hunter was touching our throats, but I was a serious and respectful student and so, during silent reading period, I did what Ms. Hunter told us to do. I kept my eyes on the material I was reading and waited for her to place her fingers lightly on my throat.One day, I raised my head from my book —though not high —so that I could see Ms. Hunter, a white woman from Canada, moving up and down the rows, stopping at the desks of myclassmates. I wanted to see how they reacted when she touched their throats. She walked past them. I was confused. Did she pass them by because they were model students? What did we, the students who were touched, not do right? I sat up straighter in my chair, thinking that my way of sitting might be the problem. I was confused. Several days later, I watched again, this time raising my head a little higher. Nothing changed. Ms. Hunter touched the same students. Always, she touched me.She touched me with her hands. She also touched me with her belief in my ability to achieve. She motivated me by demanding the best from me and by letting teachers I would meet in junior high school know that I should be challenged, that I would be serious about my work. I am convinced that she touched me because she could ―see‖ me in the future. That was true of all of us at Fair Oaks who sat still and silent as Ms. Hunter placed her fingers lightly on our throats. We left Fair Oaks as ―best students,‖ entered John Marshall Junior High School, finished at the top of our high school class, and went on to earn graduate degrees in various subjects. Ms. Hunter saw us achieving and she touched us to make certain that we would.I was not surprised that she came to my graduation ceremony at Edison High School in Stockton or that she talked to me about finishing college and earning a Ph. D. She expected that of me. She gave me a beautifully wrapped box. Inside was a gift, the beauty of which multiplies even as it touches me: a necklace to which I can add charms for each stage of my life.70. According to the writer, what is a special ability many good teachers possess?A. The ability to make all students behave well.B. The ability to treat different students in the same way.C.

A Teacher‘s MemoryDWhile residents of wealthy nations tend to have greater life satisfaction, new research shows that those living in poorer nations report having greater meaning in life.These findings, published in Psychological Science, a journal of the Association for Psychological science, suggest that meaning in life may be higher in poorer nations as a result of greater religiosity (笃信宗教). As countries become richer, religion becomes less central to people‘s lives and they lose a sense of meaning in life.―Thus far, the wealth of nations has been almost always associated with longevity, health, happiness or life sa tisfaction,‖ explains psychological scientist Shigehiro Oishi of the University of Virginia. ―Given that meaning in life is an important aspect of overall well-being, we wanted to look more carefully at differential patterns, correlates (相关物), and predictors for meaning in life.‖Oishi and colleague Ed Diener of the University of Illinois at Urbana-Champaign investigated life satisfaction, meaning, and well-being by examining data from the 2007 Gallup World Poll, a large-scale survey of over 140,000 participants from 132 countries. In addition to answering a basic life satisfaction question, participants were asked: ―Do you feel your life has an important purpose or meaning?‖ and ―Is religion an important part of your daily life?‖The data revealed some unexpected trends:―Among Americans, those who are high in life satisfaction are also high in meaning in life,‖ says Oishi. ―But when we looked at the societal level of analysis, we found a completely different pattern of the association between meaning in lif e and life satisfaction.‖When looking across many countries, Oishi and Diener found that people in wealthier nations were more educated, had fewer children, and expressed more individualistic attitudes compared to those in poorer countries –all factors that were associated with higher life satisfaction but a significantly lower sense of meaning in life.‖The data suggest that religiosity may play an important role: Residents of wealthier nations, where religiosity is lower, reported less meaning in life and had higher suicide rates than poorer countries.According to the researchers, religion may provide meaning to life to the extent that it helps people to overcome personal difficulty and cope with the struggles of working to survive in poor economic conditions:―Religion gives a system that connects daily experiences with the coherent whole (连贯的整体) and a general structure to one‘s life … and plays a critical role in constructing meaning out of extreme hardship,‖ the researchers write.Oishi and Diener hope to reproduce these findings using more comprehensive measures of meaning and religiosity, and are interested in following countries over time to track whether economic prosperity gives rise to less religiosity and less meaning in life.76. The wealth of nations has always been related to all the following except __________.A. longevityB. healthC. happinessD. a life of purpose77. Which of the following questions couldn‘t the participants have answered?A. Does your life have a purpose or meaning?B. Do you have relatives living abroad?C. Are you satisfied with your everyday life?D. Is religion involved in your daily life?79. What can be inferred from the passage?A. The poorer a country is, the more religious its people are.B. Economic prosperity gives rise to less religiosity and less meaning in life.C. If you want to find meaning in life, you must practice a religion.D. Meaning in life doesn‘t have much to do with the amount of wealth one possesses.80. The main purpose of the passage is to explain the possible reason why __________.A. greater life satisfaction leads to lower sense of meaningB. residents of poorer nations enjoy greater meaning in lifeC. residents of poorer nations are so religiousD. residents of wealthy nations have greater life satisfaction任务型阅读(共5小题,每小题1分,满分5分)Matt, Mrs. Underwood, Pico, Mr. Fishman and Mrs. Nash are intentional book buyers.
