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.

武汉公办高中入学细则一、中考招生某某某策1、普通高中招生3.49万名2、中职学校招生2.77万名3、网上填报志愿时间为5月5日8时至5月9日17时,截止时间比去年提前3小时4、体艺特长生优录变化:第二批次高中录取体艺特长生的分数不得低于一般公办普通高中录取资格线10分5、招录分配生的省级、市级示范高中仍按该校招生计划50%的名额招录分配生,4月22日统一测试6、华中师大一附中等4所普通高中继续实行网上招生,现场面试时间统一为4月22日上午二、武汉中考招生变化有哪些1、网上填报志愿截止时间提前今年,武汉市中考将继续实行网上报名。
考生直接在网上对填报的志愿进行确认填报志愿结束后不能再填报志愿或修改志愿。
另外,今年网上填报志愿截止时间由去年的20时调整到17时,具体时间为5月5日8时至5月9日17时改变时间可能会有所变化。
某录取期间,市招考办将向社会公布生源不足学校征集志愿的具体时间及办法,未被填报学校录取且符合条件的考生可在规定时间内通过武汉招考网填报征集志愿,征集志愿时间截止后,市招考办按考生升学成绩总分从高到低依次进行录取。
2、体艺特长生中考优录力度加大去年的某某某策是,第一、第二批次高中录取体艺特长生的分数,均不得低于一般公办普通高中录取资格线,今年将完善体艺特长生中考优录某某某策,进一步支持普通高中学校特色发展。
具体要求如下:第一批次高中录取体艺特长生的分数不得低于一般公办普通高中录取资格线;第二批次高中录取体艺特长生的分数不得低于一般公办普通高中录取资格线10分;一般公办普通高中录取体艺特长生的分数不得低于一般公办普通高中录取资格线30分。
这也就意味着,报考第二批次高中的体艺特长生,可在一般公办普高录取资格线的基础上降10分被录取。
三、武汉中考分配生某某某策今年招录分配生的省级、市级示范高中,仍按该校招生计划50%的名额招录分配生。
各初中根据区教育局分配的名额,按1∶2的比例确定分配生候选名单。

No matte how happy you are,it's normal to feel angry,sad or once in a while.Life is full of ups and downs.We can't change the way life is,but we can do our best to change a bad situation into a good one.To help us do this,it's good to know some of the factors (因素)that influence happiness.One of the biggest factors is social relationships.People who are close to family and friends are happier than people who don't have those relationships.Talking and sharing is a good way to relax and build confidence.Knowing someone is there for you will make you braver and more outgoing.Another factor is work or school.If you enjoy school,even if you have lots of homework or extra classes,you will still feel that your school life is meaningful and happy.But if you hate school,your negative attitude may cause you to feel bored and upset that you have to do so much work.A third factor is your attitude towards life.How do you feel if you fail in an exam Maybe you think it's unfair because you always study hard and should get a good mark.You can't stop blaming yourself.Or,maybe you accept it.You go through the paper carefully,find out why you made stupid mistakes,and tell yourself,"Take it easy!I'll do better next time!" Your attitude makes a big difference.31. The writer tells us ______ factors that influence happiness.A. twoB. threeC. fourD. five32. If you fail in an exam you should ______ .A. blame yourselfB. complain about othersC. work harder than beforeD. go through the paper again33. Which of the following is true according to the passage______A. Life is always full of happiness.B. When you cry,the world cries with you.C. It's normal if you sometimes feel sad and gloomy.D.

Which of the following is probably the best title for the passage______A. Make Trouble Easy to Handle.B. Your School Life is happy.C. The World Smiles with You.D. You Make Your Own Happiness.MWhat will man be like in the future——in 5000 or even 50,000 years from now?We can only make guesses,of course,but we can be sure that he will be different from what he is today,for man is slowly changing all the time.Let us take an obvious example.Man,even five hundred years ago,was shorter than he is today.Now,on average,men are about three inches taller.Five hundred years is relatively short period of time,so we may assume that man will continue to grow taller.Again,in the modern world we use our brains a great deal.Even so,we still make use of only about 20% of the brain's capacity.As time goes on,however,we shall have to use our brains more and more,and eventually we shall need larger ones!This is likely to bring about a physical change to the head,in particular the forehead,will grow larger.Nowadays our eyes are in constant use.In fact,we use them so much that very often they become weaker and we have to wear glasses.But over very long period of time it is likely that man's eyes will grow stronger.On the other hand,we tend to make less use of our arms and legs.These,as a result,are likely to grow weaker.At the same time,however,our fingers will grow more sensitive because they are used a great deal in modern life.But what about hair?This will probably disappear from the body altogether in courseof time because it does not serve a useful purpose any longer.In the future,then,both sexes are likely to be bald.Perhaps all this gives the impression that future man will not be a very attractive creature to look at!This may well be true.All the same,in spite of all these changes,future man will still have a lot in common with us.He will still be a human being,with thoughts and emotions similar to our own.36. The passage mainly tells us that ______ .A. man's life will be different in the futureB. future man will look quite different from usC. man is growing taller and uglier as time passesD. the functions of man's organs(器官)will function as well as today37. Which of the following serves as the evidence that man is changing?______A. Man's hair is getting thinner and thinner.B. Man has got stronger eyes now than he ever had.C. Man has been growing taller over the past 500 years.D. Man's arms and legs have become lighter and weaker.38. The change in man's size of forehead is probably because ______ .A. he makes use of only 20% of the brain's capacityB. the other 80% of his brain will grow in due (预定的)timeC. his brain has grown larger over the past centuriesD. he will use his brain more and more as time goes on39. Which of the following is true about a human being in the future?______A. He thinks and feels in different ways.B. He has smaller eyes and wears better glasses.C. He is hairless because hair is no longer useful.D. His fingers grow weaker because he doesn't use them.40. It can be inferred from the passage that ______ .A. future life is always predictable (可预测的)B. human beings hope for a change in the future lifeC. human beings will become less attractive in the futureD. Less use of a bodily organ may lead to its degeneration (衰退)NA new report says living in a city makes it harder for people to concentrate(集中)on some tasks.The research found that people who live in rural(乡村的)areas can focus better than people in urban(城市的)areas.The study is from Goldsmiths College,which is part of the University of London.Head researcher Dr.Karina Linnell and her team made great contributions.They studied how two groups of people did the same "thinking tasks".The team went to a remote(偏远的)part of Namibia,southwest Africa,to study the Himba tribe.Himba people live a very basic life in the desert.They are still doing traditional farming.The team also studied members of the same tribe who had moved to the nearest town.Dr.Linnell said the tribe who lived in the desert did much better on the tests than those in the town.It's really interesting and shocking.Dr.Linnell said their research may lead to changes in the way companies operate.In the future,workers may move from cities to live and work in the countryside.Linnell said there are too many things around us in the city that stop us from thinking about one thing for a long time.This means we do not work at our best.She asked,"What if,for example,companies realized certain tasks would be better carried out by employees based outside of the urban environment There their concentration ability is better. "The past century has seen billions of people move from the countryside to big cities.In the future,the trend may not continue.If Dr.Linnell's research is true,this century might see many of those people return to the great .Let's wait to see what will happen. 41. What did Dr.Linnell and her team conclude from the study on the Himba tribe______A. Himba people are cleverer than others.B. Himba people aren't used to the life in city.C. Himba people focus better in the desert.D. Himba people give up traditional farming.42. What happened in the past one hundred years?______A. Many people returned to the countryside.B.

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. 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. 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. 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.
