Unit 2Working the landⅠ.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,“It’s like an insurance policy. Having access to those tree-based food is hugely important when you can’t 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 aimsfor 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.The sharp decrease of forests.2.Which can solve the problem discussed in the text according to Mr. Vira?A.Better living conditions.B.Insurance policies.C.Tree-based 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 populationB.Forests can help feed the worldC.The importance of forest healthD.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 combination 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 plants—those 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 they’re not putting in organic matter.They’re not putting in fertilizers.They can’t afford those things.And it just runs the soil down. So they’re 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.“She’s 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.Ⅱ.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。
