Ⅲ.阅读理解
(2017·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.”
1．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
2．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.
3．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.
4．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
5．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.

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，长处；good好处，益处；welfare福利，幸福。由“只要提供身份证明”可知，应为享有某些特权而不是好处或福利。
答案： C
6．解析： 考查介词with加复合宾语结构，这里是with China participating in the world trade，因为中国加入世界贸易，主动关系用现在分词作宾语补足语。
答案： A
7．解析： 考查虚拟语气。句意为：——你的伦敦之旅怎么样？——很好，我得到了一个机构的帮助。否则，我是支付不起这个费用的。根据Otherwise和was可知，此处表示的是与过去事实相反的虚拟语气，故用would/could/might have done结构，再结合选项可知应选C。
答案： C
8．解析： 考查动词辨析。句意为：这位母亲为了给她的女儿良好的教育，牺牲了许多东西。purchase购买；produce生产；sacrifice牺牲；store储存。
答案： C
9．解析： 考查主语从句。句意为：是否能够立即采取措施防止地下水污染还很难说。根据句意并分析句子成分可知，it是形式主语，空处引导一个主语从句，是句子的真正主语。故应该用whether，表示“是否”。
答案： B
10．解析： 考查介词短语辨析。句意为：受战争，贫穷和疾病的折磨，许多非洲的孩子需要食物，爱和关心。in need of需要，符合句意。in case of以防万一；in charge of掌管；in face of面对。
答案： D
11．解析： 考查连词辨析。句意为：奶奶把钥匙留给了邻居，以防万一有一天她将自己锁到门外。A项意为“只要”；B项意为“尽管，即使”；C项意为“以防万一”；D项意为“好像，仿佛”。
答案： C
12．解析： 考查强调句式。句意为：直到我游览了桂林，我才发现它真是一个名副其实的好地方。本句为“It was...that...”强调句型，被强调的部分是时间状语“not until I visited Guilin”。
答案： A
13．解析： 句意为：“我”一觉醒来已是午夜，所以我的眼睛过了几秒后才适应了黑暗。adjust to适应，调节，符合语境。
答案： B
14．解析： 考查动词短语辨析。set up建立；pick up捡起，学会，习得；speed up加速；dry up干涸，枯竭。句意为：金先生在写完第三本小说之后，好像他的想象力已经枯竭，所以他决定周游世界以开拓视野。
答案： D
15．解析： 考查定语从句。句意为：在我看来，每个人在他们的生命中都有一段时期，在这段时期里，每件事都好像特别难。分析句子结构可知，这是一个定语从句，先行词是periods，在定语从句中作时间状语。
答案： A

Ⅳ.写作
Recently an activity has been going on in our school which is called “Becoming a Guardian to Protect the Environment”．Students are asked to hand in used batteries，newspaper and so on to get a card as a reward.I think we can benefit a lot from this activity.
Firstly，this activity will help to raise our environmental awareness and save resources.Secondly，the used batteries are harmful to the environment.Recycling them has been of great importance in terms of conserving
natural
resources，environment
protection
and
human health.
Meanwhile，we can still do a lot more to help protect the environment.For example，we should remember to turn off the light before we leave the room.And we shouldn’t leave the tap water running
after we use it.
