农耕词汇在当代语境焕发生机①农耕词汇是一类独特的语言资源,与农具、环境和农业耕作方式等农业生产生活直接相关。
现代工业社会飞速发展的科学技术,使农业生产方式发生了翻天覆地的变化。
值得注意的是,在当今社会语境下,农耕词汇并未完全消亡,甚至在一定程度上进发出新的活力。
一方面,播种、栽培、嫁接、灌溉、施肥、耕耘等常用农耕词汇,在使用与传播的过程中纷纷发生语义泛化现象,融入了汉语的基本思维习惯,成为日常语言的一部分。
另一方面,部分农耕词汇不仅自然融入大众话语之中,还现身于新闻话语、学术话语等专业话语中,并在与这些专业话语的良性互动中显示出无可比拟的表达优势。
②一类收耕词汇与农事生产活动有关,如耕、割、播、藏、锄等。
“耕”指用犁翻松填土以备播种。
“深耕”是土壤耕作的最基本措施,播种、插秧等农事活动之前必先犁田,上翻深层土壤,下盖浅层土壤,耙地等耕作劳动必须以深耕为基础。
中国自古就有“深耕浅种”“深耕细作”等表达。
在当今社会生活中,“深耕”一词的使用愈加广泛,与其相关的新闻话语表达越来越常见,如“深耕国内市场”“深耕本土文化”“深耕数十载”等。

At the time, I never gave any thought to publishing them; I just wrote for my own amusement. But it was so much fun that I ended up writing a lot of poems, which led me to the idea of creating a website, and at last writing books. If you want to write poems, I have some advice for you.My ideas mostly come from my imagination. That is, I like to sit and daydream, and see what kinds of crazy things I can think up. For kids, I suggest that whenever you think of an idea, you should write it down, even if you don’t have time write them to create a whole poem from your idea. I have notebooks full of ideas that I haven’t written poems about yet. So I can always look through my notebooks and fi nd something fun to write about.One way to make poems interesting is to write about things readers can understand: school, family, food, pets, games, sports, and so on. To make a poem funny, I often ask myself, “What kinds of funny things might happen at school, or over dinner? What funny things might your pets do?” and its OK to make things up. such as having a pet elephant, or a pet that plays video games. Use your imagination and see where it leads. But if you write ten poems, you’ll probably find that, even though they aren’t all perfect, a few of them are much better than the others.31. Why did the author start writing poems at first?A. To publish them.B. To entertain himself.C. To contribute to a website.D. To kill time.32. What’s the main i dea of paragraph 2?A. How to write poems.B. How to think up crazy things.C. How to get ideas for poems.D. How to became creative.33. According to the author, what is the best advice he can give us?A. Just write great poems.B. Write as many as possible.C. Make poems as funny as possible.D. Try to make things up in your poems.34. Where does the author come from?A. AmericaB. ChinaC. GermanyD. not clear35. What’s the author’s purpose of writing the text?A. To suggest some poems written by him.B. To show writing poems isn’t that hard.C. To tell readers how to write poems.D. To explain how he writes poems.BHave you gone for a run lately? Have you maybe run for a marathon, a total of 42km? Imagine running this 42km every day, finally reaching a total of 5376km. That would be 128 days of running, more than halfway across Canada. Meet a man who has done all this – but on only one real leg! Meet Terry Fox.Terry Fox was born in Winnipeg Canada, only July 28th, 1958. He won many awards for playing sports when he was small. He went to university to be a P.E. teacher. In 1977, however, something happened that was going to change him for life. One day, he came home complaining about a pain in his knee. The pain was really bad so he went to the hospital. There he found out he had cancer. To stop the spread of the cancer, doctors had to cut off his leg.He replaced his old leg with an artificial one, and in 3 weeks he was walking again. He felt good about beating cancer. Just before his surgery he had read about Dick Traum. This man had lost a leg too, and he had run the New York City marathon. That inspired Terry Fox for the rest of his life.Fox started training and ran his first marathon in 1979. His aim is to run all the way across Canada to raise one dollar per Canadian for cancer research. He started on April 12th in St John’s, a town on the Atlantic Coast. By July he had reached Toronto and he was welcomed by 10,000 supporters. He kept going west at the pace of 42km per day, on his way north, just on the outskirts of Thunder Bay he had to stop. He hadn’t completely defeated the cancer, and now it had spread to his lungs. He had to quit running and fly back home for treatment.Terry Fox inspired many people who raised more money for his cause. In January 1981 not long before Fox passed away, his dream became true. He had raised 24.1 million dollars, equaling the population of Canada.36. Why did Terry Fox start running marathons?A. Because he had only one leg.B. To stop the spread of the cancer.C. To tell his family and friends that he was well.D. To help cancer research.37. From the passage, we know that Canada is_____ wide.A. 2,688 kmB. 5,376kmC. 10.752kmD. 21,504km38. How old was Terry Fox when he started running marathons?A. 21B. 19C. 23D. Unknown39. Which of the following statements is true?A. Terry Fox won many awards on only one leg.B. Terry Fox ran to raise money for his treatment.C. Terry Fox was encouraged by Dick Traum.D. Terry Fox raised 24 million dollars.40. What does the underlined word “artificial” in the third paragraph mean?A. realB. man-madeC. strongD. healthyCDo you want to know something about the history of weather? Don’t look at the sky. Don’t look for old weather reports. Looking at tree rings is more important. Correct weather reports began only one century ago, but some trees can provide an exact record of the weather even further back.It is natural that a tree would grow best in a climate(气候) with plenty of sunlight and rainfall. It is also expected that little sunlight and rainfall would limit the growth of a tree. The change from a favorable to an unfavorable climate can be decided by reading the pattern of rings in a tree trunk(树干). To find the weather of ten years ago, count(数) the rings of a tree trunk from the outside to the inside. If the tenth ring is far from the other rings, then it is certain that there was plenty of sunny and rainy weather in that year. If the rings are closed together, then the climate was bad for the tree.Studying tree rings is important not only for the history of weather, but also for the history of man.In an area of New Mexico you can find only sand--- no trees and no people. However, many centuries ago a large population lived there. They left suddenly. Why?A scientist studied patterns of dead tree rings which had grown there. He decided that the people had to leave because they had cut down all the trees. Trees were necessary to make fires and buildings. So, after the people destroyed the trees, they had to move. In this situation studying tree rings uncovers an exciting fact about the history of man.41. It is understood that in a good climate__________.A. tree rings grow togetherB. tree rings grow far apartC. trees in New Mexico will grow big and tallD. people can cut down most of the trees in New Mexico42. The scientists are interested in studying tree rings because they can tell_______.A. whether in that area the climate was good or notB. whether a particular tree was healthy or notC. whether people took good care of the trees or notD. how old the trees were43. By studying the dead tree rings in an area of New Mexico, the scientist discovered________.A. where the people had left.B. what the people used to eatC. how the people leftD. why the people had to leave44. The people had to leave the area of New Mexico because_______.A. they had cut down all the treesB. there were many trees thereC. they had no waterD. bad weather stopped the growth of trees45. What can be the best title for the passage?A. How ancient people told weatherB. Connections between weather and treesC. Weather and tree ringsD. Tree rings and human history四、阅读理解填词(本题10空,每空0.5,满分5分)When learning to drive, we’re told to obey the traffic rules and not to drive our cars too fast.

At the time, I never gave any thought to publishing them; I just wrote for my own amusement. But it was so much fun that I ended up writing a lot of poems, which led me to the idea of creating a website, and at last writing books. If you want to write poems, I have some advice for you.My ideas mostly come from my imagination. That is, I like to sit and daydream, and see what kinds of crazy things I can think up. For kids, I suggest that whenever you think of an idea, you should write it down, even if you don’t have time write them to create a whole poem from your idea. I have notebooks full of ideas that I haven’t written poems about yet. So I can always look through my notebooks and find something fun to write about.One way to make poems interesting is to write about things readers can understand: school, family, food, pets, games, sports, and so on. To make a poem funny, I often ask myself, “What kinds of funny things might happen at school, or over dinner? What funny things might your pets do?” and its OK to make things up. such as having a pet elephant, or a pet that plays video games. Use your imagination and see where it leads. But if you write ten poems, you’ll probably find that, even though they aren’t all perfect, a few of them are much better than the others.31. Why did the author start writing poems at first?A. To publish them.B. To entertain himself.C. To contribute to a website.D. To kill time.32. What’s the main idea of paragraph 2?A. How to write poems.B. How to think up crazy things.C. How to get ideas for poems.D. How to became creative.33. According to the author, what is the best advice he can give us?A. Just write great poems.B. Write as many as possible.C. Make poems as funny as possible.D. Try to make things up in your poems.34. Where does the author come from?A. To suggest some poems written by him.B. To show writing poems isn’t that hard.C. To tell readers how to write poems.D. To explain how he writes poems.BHave you gone for a run lately? Have you maybe run for a marathon, a total of 42km? Imagine running this 42km every day, finally reaching a total of 5376km. That would be 128 days of running, more than halfway across Canada. Meet a man who has done all this – but on only one real leg! Meet Terry Fox.Terry Fox was born in Winnipeg Canada, only July 28th, 1958. He won many awards for playing sports when he was small. He went to university to be a P.E. teacher. In 1977, however, something happened that was going to change him for life. One day, he came home complaining about a pain in his knee. The pain was really bad so he went to the hospital. There he found out he had cancer. To stop the spread of the cancer, doctors had to cut off his leg.He replaced his old leg with an artificial one, and in 3 weeks he was walking again. He felt good about beating cancer. Just before his surgery he had read about Dick Traum. This man had lost a leg too, and he had run the New York City marathon. That inspired Terry Fox for the rest of his life.Fox started training and ran his first marathon in 1979. His aim is to run all the way across Canada to raise one dollar per Canadian for cancer research. He started on April 12th in St John’s, a town on the Atlantic Coast. By July he had reached Toronto and he was welcomed by 10,000 supporters. He kept going west at the pace of 42km per day, on his way north, just on the outskirts of Thunder Bay he had to stop. He hadn’t completely defeated the cancer, and now it had spread to his lungs. He had to quit running and fly back home for treatment.Terry Fox inspired many people who raised more money for his cause. In January 1981 not long before Fox passed away, his dream became true. He had raised 24.1 million dollars, equaling the population of Canada.36. Why did Terry Fox start running marathons?A. Because he had only one leg.B. To stop the spread of the cancer.C. To tell his family and friends that he was well.D. To help cancer research.37. From the passage, we know that Canada is_____ wide.A. 2,688 kmB. 5,376kmC. 10.752kmD. 21,504km38.

What does the underlined word “artificial” in the third paragraph mean?A. realB. man-madeC. strongD. healthyCDo you want to know something about the history of weather? Don’t look at the sky. Don’t look for old weather reports. Looking at tree rings is more important. Correct weather reports began only one century ago, but some trees can provide an exact record of the weather even further back.It is natural that a tree would grow best in a climate(气候) with plenty of sunlight and rainfall. It is also expected that little sunlight and rainfall would limit the growth of a tree. The change from a favorable to an unfavorable climate can be decided by reading the pattern of rings in a tree trunk(树干). To find the weather of ten years ago, count(数) the rings of a tree trunk from the outside to the inside. Ifthe tenth ring is far from the other rings, then it is certain that there was plenty of sunny and rainy weather in that year. If the rings are closed together, then the climate was bad for the tree.Studying tree rings is important not only for the history of weather, but also for the history of man. In an area of New Mexico you can find only sand--- no trees and no people. However, many centuries ago a large population lived there. They left suddenly. Why?A scientist studied patterns of dead tree rings which had grown there. He decided that the people had to leave because they had cut down all the trees. Trees were necessary to make fires and buildings. So, after the people destroyed the trees, they had to move. In this situation studying tree rings uncovers an exciting fact about the history of man.41. It is understood that in a good climate__________.A. tree rings grow togetherB. tree rings grow far apartC. trees in New Mexico will grow big and tallD. people can cut down most of the trees in New Mexico42. The scientists are interested in studying tree rings because they can tell_______.A. whether in that area the climate was good or notB. whether a particular tree was healthy or notC. whether people took good care of the trees or notD. how old the trees were43. By studying the dead tree rings in an area of New Mexico, the scientist discovered________.A. where the people had left.B. what the people used to eatC. how the people leftD. why the people had to leave44. The people had to leave the area of New Mexico because_______.A. they had cut down all the treesB. there were many trees thereC. they had no waterD. bad weather stopped the growth of trees45.
