Unit 2 Working the land.阅读理解A(2017福建泉州适应性考试)Experts predict nine billion people will live on our planet by 2050. They say by that time the demand for food will be two times what it is now. Officials are worried about that prediction because many people have already suffered from a lack of food. More than 800 million people go to bed hungry.A solution(解决办法)to the problem may be turning to our forests. A new report says forests can help reduce hunger and improve nutrition if they are properly managed.Bhaskar Vira is the director of the University of Cambridge Conservation Research Institute and an expert of the International Union of Forest Research Organizations (IUFRO). It recently released a report at the United Nations about forests and jungle food.Mr. Vira says crops that grow on trees can help feed people living in and around forests. He said,“Its like an insurance policy. Having access to those tree-based food is hugely important when you cant buy food from other sources or when your crops failed.”The report says that forest health and economic value will improve when people who live in or near forests are given greater control of them. For example, a project in Ghana aims for proper management of forests and fields. The people involved hope to grow the Allanblackia plant. The oil from its seeds can be used in soap, beauty products and food.Okai Michael Henchard leads the project. He says he will help people who live nearby. He says they will earn money and get trees on their land. The trees provide shade and improve the air quality. Mr. Henchard says the project also helps fight against climate change.1.What are officials worried about?A.Pollution and starvation.B.The large population and health.C.The great demand for food.

D.More fields.3.What is the initial purpose of the project in Ghana?A.To manage forests and fields. B.To grow the Allanblackia plant.C.To produce more oil.D.To beautify the environment.4.What would be the best title for the text?A.A solution to controlling the population B.Forests can help feed the worldC.The importance of forest health D.The project in Ghana helps the nativesB(2017湖南张家界模拟)Studies show farmland in Africa is often lacking in important nutrients.But researchers say a bination of farming methods may help.Researchers wonder how to increase production without necessarily clearing more land to grow additional crops.American researchers say that can happen with greater use of an agricultural system called perenniation.It mixes food crops with trees and perennial plantsthose that return year after year.Soil scientist John Reganold says,“One of the major problems is that the soils are fairly poor in most of the regions.So how do you grow food on poor soils? There have to be food production systems that can build the soil and improve the yield.”Mr. Reganold says poor soil may have resulted from years of weathering that washed away many nutrients.He says some farmers may have done more harm than good.“They have been actually using farming practices where theyre not putting in organic matter.Theyre not putting in fertilizers.They cant afford those things.And it just runs the soil down. So theyre worsening the situation.”The scientist says the word perenniation defines three systems that are already used in Africa.The oldest of the three is called evergreen agriculture.This is where farmers plant trees with their crops.Farmers in Africa have been doing this for sixty years, but it seems to be growing in popularity.The method is gaining widespread use in countries such as Niger, Burkina Faso, Malawi and Zambia.The trees are planted among maize (玉米), millet or sorghum crops.They not only add nitrogen (氮) to the soil through their roots, but also through their leaves when they fall off and break down.At other times of the year, the trees can protect plants from strong sunlight.John Reganold says he knows of one woman who has had great success with perenniation.“Shes a grandmother in her fifties.Her name is Rhoda and she started using this system about twenty years ago.And her yields initially were about a ton of maize.Now with a good year she gets four tons per hectare, four times what she was getting.”5.The purpose of the passage is to .A.tell people how to increase productionB.introduce an agricultural system in AfricaC.introduce the oldest farming method in AfricaD.tell us how to prevent soil from being poor6.What does the underlined word “weathering” in Paragraph 4 most probably mean?A.Being exposed to wind and rain.B.Growing different crops.C.Being polluted severely.D.Being ploughed improperly.7.According to the passage, which of the following statements is WRONG?A.Perenniation mixes food crops with trees and perennial plants.B.Poor soil is the main problem in increasing food production.C.Farmers may be more to blame for the present situation.D.American researchers first invented perenniation.8.Why does John Reganold mention Rhoda?A.To show the method is very popular in Africa.B.Because she is an expert at farming production.C.To prove the farming method is effective.D.Because she produced more grains than anyone else in the country.语法填空阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。Mr.Johnson lived in the woods with his wife and children.He owned1farm,which looked almost abandoned.2(lucky),he also had a cow which produced milk every day.He sold or exchanged some of the milk in the towns nearby3other food and made cheese and butter for the family with what4(leave).The cow was their only means of support,in fact.One day,the cow was eating grass5it began to rain heavily.While making great efforts to run away,she6(fall)over the hill and died.Then the Johnsons had to make a living7the cow.In order to support his family,Mr.Johnson began to plant herbs and vegetables.Since the plants took a while to grow,he started cutting down trees8(sell)the wood.Thinking about his childrens clothes,he started growing cotton too.When harvest came around,he was already selling herbs,vegetables and cotton in the market9people from the towns met regularly.Now it occurred to10that his farm had much potential and that the death of the cow was a bit of luck.1. 2. 3. 4. 5.6. 7. 8. 9. 10.短文改错假定英语课上老师要求同桌之间交换修改作文,请你修改你同桌写的以下作文。文中共有10处语言错误,每句中最多有两处。每处错误仅涉及一个单词的增加、删除或修改。增加:在缺词处加一个漏字符号(),并在其下面写出该加的词。删除:把多余的词用斜线()划掉。修改:在错的词下画一横线,并在该词下面写出修改后的词。注意:1.每处错误及其修改均仅限一词;2.只允许修改10处,多者(从第11处起)不计分。Im angry to see some schoolmates throw away food in the school canteen, which make me very concerned.
