(2020·江西省赣中四校高三第二次联考)

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 Mang’yana 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.”

6．The purpose of the passage is to________. A．tell people how to increase production B．introduce an agricultural system in Africa C．introduce the oldest farming method in Africa D．tell us how to prevent soil being poor

7．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.

8．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.

9．Evergreen agriculture is popular with the farmers mainly because it________.

A．can build the soil and improve the yield B．can provide more wood as well C．is the easiest method to carry out D．is used for a long time

10．Why does John Reganold mention Rhoda Mang’yana? 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. Ⅲ.书面表达

课时作业(三十四) Ⅰ.单项填空

1．解析： 考查交际用语。句意为：——我想我现在必须离开了。明天见。——等等！我有一些重要的信息要告诉你。根据句意可知，Hang on等等，等一下，正确。

答案： A

2．解析： 考查代词。由空后是一个介词短语可判断该空引导的不是定语从句，由此排除A、D两项；同时可判断该空需用一代词作monitor的同位语，因此选one指代a monitor。句意为：我们非常需要一个更有能力的班长，他既要诚实又要有幽默感。

答案： C

3．解析： 考查情态动词。句意为：——在每天十亿次点击量的网站上订到一张票是一项艰难的任务。——我完全同意你。而且每一个步骤都有可能会出错。根据语境，答话人表达的是对困难情况的一种推测。can有可能，会，表示可能性，符合语境。

答案： C

4．解析： 考查定语从句。先行词the day和定语从句被谓语动词隔开，关系词在从句中作时间状语，故用when。

答案： A

5．解析： 考查名词辨析。privilege特权，特别优待；advantage优点，长
