五、阅读理解
Organic(有机的) farming is a type of agriculture that benefits from the recycling and use of natural products.Use of dried plants not only saves money,but also ensures the growth of crops.The technique is characterized by the use of green manure(肥料),biological pest control methods and special farming techniques to keep soil productivity.Limiting the use of man-made chemicals or completely doing away with them reduces the risk of diseases.Today,organic farming is a major and preferred industry around the world.Organically grown food products have a huge market,with farmlands covering about 10% of the total world-farmland cover.The hard work of sir Albert Howard,the Father of Organic Farming,has paid off.?
Advantages of Organic Farming:
(1)The economics of organic farming are characterized by increasing profits through reduced water use and reduced soil erosion(侵蚀).
(2)Organic farming produces the same crops as those produced through traditional farming methods,but uses half the energy,and holds 40% more topsoil.
(3)Farming the organic way enables farmers to get rid of weeds without the use of any chemicals.
(4)The use of green pesticides(杀虫剂) is environmentally friendly and does no harm to human’s health.
Disadvantages of Organic Farming:
(1)Organic methods of farming produce less,compared to traditional farming techniques.
(2)Organic agriculture does little to fight global climate change.Though organic farming practices are recognized as giving out less CO2,but not to a significant degree.
However,though there are some disadvantages to organic farming,farms where organic methods for cropping have been used have more advantages than traditional farms.Organic agriculture is surely better in the long term.
1.The underlined sentence in Paragraph 1 shows that sir Albert Howard .?
A.worked hard for nothing
B.succeeded in organic farming
C.spent all his time on organic farming
D.didn’t expect organic farming to be successful
答案B
解析推理判断题。根据画线句前一句的“with farmlands covering about 10% of the total world-farmland cover”以及画线句子中的“hard work...has paid off”可推断,sir Albert Howard在有机农业研究和种植方面是成功的。
2.According to the passage,compared to traditional farming,organic farming .?
a.is more environmentally friendly
b.produces a lot more food
c.uses less energy
d.results in more weeds in the farmland
e.is better for human’s health
A.abc B.acd
C.ace D.bce
答案C
解析细节理解题。根据优点中第二点的uses half the energy,第四点的environmentally friendly和does no harm to human’s health可知ace都是有机农业胜于传统农业的地方,故选C项。
3.The author’s attitude toward organic farming is .?
A.anxious B.hopeless
C.unclear D.optimistic
答案D
解析推理判断题。根据末段的“Organic agriculture is surely better in the long term.”可知作者对有机农业的未来充满信心。
4.The writer wrote this passage to tell us .?
A.the development of agriculture
B.what kind of food is being grown at present
C.why organic farming is so popular around the world
D.what organic farming is and its advantages and disadvantages
答案D
解析写作意图题。通读全文可知,作者主要告诉了我们什么是有机农业以及其优缺点,故选D项。

课件50张PPT。Unit 2 Working the land【语篇导读】袁隆平试种的包括“海水稻”在内的80多个水稻品种分批成熟。他领导的海水稻项目使中国技术处于海水稻研究的前列。
China,a further step toward its future practical use.Also known as saline-alkali tolerant rice (耐盐碱水稻),the seawater rice is designed to grow in seaside flats or other areas with high salt content and has been developed by experts through crossbreeding(杂交) and other
technologies①.One type of seawater rice growing in Qingdao’s Chengyang district,Shandong Province,produced 3.9 metric tons (公吨) per hectare (公顷),experts announced②.Once widely planted in large areas,the output could be much higher.
The Qingdao Saline-Alkali Tolerant Rice Research and Development Center,led by renowned Chinese agricultural scientist Yuan Longping,was established③ several years ago.It set itself a three-year target of developing a kind of salt-resistant rice capable of producing 4.5 tons a hectare,which would guarantee④ growers the minimum acceptable level of profit.The average⑤ rice output in China is 6.75 tons a hectare.?Planting in the experimental field in Chengyang district and five other plots of saline-alkali land started at the end of May.The five other plots were in Dongying,Wenzhou,Yan’an,Kashgar,and Daqinge.The sites represent actually every type of saline-alkali land in China and researchers aim to grow different kinds of rice able to cope with different climate,salinity and soil structure conditions.
The test crops in Kashgar and Daqing were also harvested.In Kashgar,the output reached more than 7.5 tons per hectare,according to experts’ tests,much higher than expected.The harvest in Kashgar was satisfactory.The result means it is possible to plant such salt-resistant rice in southern Xinjiang in the future.Xinjiang has about 2 million hectares of saline-alkali land that have the potential to be planted with salt-resistant rice,and if it is widely planted it will generally improve rice production in the region.The seawater rice grown in Daqing only produced 3.1 tons per hectare.A live video on Shandong TV showed growers appearing a little disappointed by the result,as they hoped the experts’ efforts would increase production greatly.The water and soil conditions of the site were not ideal,and the pH level was extremely high.

A
Carrots are grown on farms and in family gardens throughout the world.Carrots are easy to raise and easy to harvest.They taste good.
When people think of carrots,they usually picture in their minds a vegetable that is long,thin and orange in colour.But carrots come in many different sizes and shapes.And not all carrots are orange.For the best results,carrots should be grown in sandy soil that does not hold water for a long time.The soil also should have no rocks.To prepare your carrot garden,dig up the soil,loosen it and turn it over.Then,mix in some plant material or animal fertilizer.Weather,soil conditions and age will affect the way carrots taste.Experts say warm days,cool nights and a medium soil temperature are the best conditions for growing carrots that taste great.
Carrots need time to develop their full sugar content.This gives them their taste.But carrots lose their sweetness if you wait too long to remove them from the ground.The best way to judge if a carrot is ready to be harvested is by its colour.Usually,the brighter the colour,the better the taste.
Carrots are prepared and eaten in many different ways.They are cut in thin pieces and added to other vegetables.They are cooked by themselves or added to stews.Or,once they are washed,they are eaten just as they come out of the ground.
1.Why should people harvest carrots at proper time?
A.Because people sometimes are very busy.
B.Because carrots have different kinds.
C.Because it takes time for carrots to keep sugar.
D.Because weather always changes.
答案C
解析细节理解题。根据第三段第一句“Carrots need time to develop their full sugar content.”可知,胡萝卜需要时间来逐渐积累糖分。故选C项。
2.Which of the following actions is not likely to be needed in planting carrots?
A.Digging up the soil.
B.Choosing muddy land.
C.Making the earth become loose.
D.Mixing in plant material or animal fertilizer.
答案B
解析细节理解题。根据第二段第四句“For the best results,carrots should be grown in sandy soil that does not hold water for a long time.”可知,胡萝卜需要被种植在沙土里。B项意为“选择泥泞的土地”,此项内容并非种植胡萝卜需要的。A、C、D三项可以从第二段第六、七句找到相对应的信息。故选B项。
3.What do we know about carrots?
A.They are easy to raise but hard to harvest.
B.All carrots are not orange.
C.Only one factor affects the way carrots taste.
D.It is only by colour that you can decide if you should harvest them.
答案B
解析细节理解题。根据第二段第三句“And not all carrots are orange.”可知,并非所有的胡萝卜都是橙色的。B项中的All...not也是部分否定的表达方式。故选B项。
4.What is the best title for the passage?
A.How to Harvest Carrots
B.How to Cook Carrots
C.Different Weather,Different Sizes
D.Carrots
答案D
解析主旨大意题。本文讲的是在世界范围内广受欢迎的胡萝卜,介绍了其形态、种植方法、生长条件、食用方法等。A、B、C三项不能全部概括文章内容,故D项符合题意。
B
Man is a land animal.But he is also closely tied to the sea.Throughout history the sea has served the needs of man.The sea has provided man with food and a convenient way to travel to many parts of the world.Today,nearly two thirds of the world’s population live within 80 kilometers of the sea coast.
In the modern technological world,the sea offers many resources to help mankind survive.Resources on land are beginning to be used up.The sea,however,still can be hoped to supply many of man’s needs.
The list of riches of the sea yet to be developed by man’s technology is big.Oil and gas explorations have been carried out for nearly 30 years.Valuable amounts of minerals exist on the ocean floor ready to be mined.
Fish farming promises to be a good way to produce large quantities of food.The culture(养殖) of fish and shellfish(贝类动物) is an ancient skill practised in the past mainly by Oriental people, including people in China.?
Besides oil and gas,the sea may offer new sources of energy.Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship.Ocean currents and waves offer possible use as a source of energy.
Technology is enabling man to explore even more deeply under the sea.The development of strong,new materials has made this possible.
The technology to harvest the sea continues to improve.Experts believe that by the year 2020 the problems that prevent us from exploiting(开发) fully the food,minerals,and energy sources of the sea will be largely solved.
5.Valuable amounts of minerals are .?
A.in the ocean water B.in the warm ocean water
C.on the sea coast D.on the ocean floor
答案D
解析根据第三段最后一句“Valuable amounts of minerals exist on the ocean floor ready to be mined.”可知,许多有价值的矿物质储藏在海底。故选D项。
6.The underlined words “Oriental people” in the fourth paragraph probably mean .?
A.Asian people B.African people
C.European people D.American people
答案A
解析根据第四段中的画线词后面的“including people in China”可知A项正确。
7.We can conclude from this passage that .?
A.the sea resources have largely been used up
B.the sea,in the broad sense,has not yet been developed
C.the problems that prevent us from using the food,minerals,and energy sources of the sea have already been solved
D.by the year 2020,the technology will be good enough to exploit all the sea resources
答案B
解析根据第三段第一句“The list of riches of the sea yet to be developed by man’s technology is big.”可知B项正确,A项错误。根据最后一段最后一句可知C、D两项错误。
五、七选五阅读理解
根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Summer is the perfect time to relax.As you plan for your trip,here are some tips on how to protect yourself.1./
Fight against the mosquitoes in the hot spots.
There are many mosquito-borne illnesses in tropical areas,which are traditionally hot vacation spots.Therefore,mosquito repellent (驱蚊剂)that contains DEET should be an essential item in your travel bag.
2. ?
In less-developed countries there is less equipment for clean water and public health.If you can’t avoid unhealthful water,make sure you bring along a tea or coffee-making pot that will boil water for you.You’d better buy a case or two of water and make sure the bottled water isn’t just a refilled bottle of dirty tap water.
Always protect your feet.
It’s best to wear slippers in the shower,but if you must be barefoot,put a towel down on the floor.3. You should never walk barefoot in any area of a foreign country,including your hotel room.?

第二,所续写内容与所给材料结合在一起,必须是一个完整的文章或片段。上下文衔接要自然,前后要照应。针对训练
阅读下面短文,根据所给情节进行续写,使之构成一个完整的故事。
A long time ago,there lived a very,very wise king.He was so wise that he knew the ways of almost everything.
Then one day,a tiny bee lost her way and flew right into the king’s beautiful palace.The little bee begged the king,“ Please,let me live,and I will serve you some other day.”The king was amused to think a tiny bee could one day serve such a powerful king.He released the bee and said,“On your way,for I need nothing from you today.”?
Many days later,the people of the kingdom filled the palace yard.A queen was coming to visit from a faraway land.She heard many people claim this king was very wise.She had to know for sure that they were not all just lies.?“I hear you are wise,” she said.“You are wiser than the rest.Would you be willing to put your wisdom to a test?” The king agreed,and she did her best with puzzles,tricks,and difficult tests,but all in vain.
Now the queen was quite angry at the king’s show of wisdom,and was more determined to find a way to trick him.“We must have a test,” she challenged her advisors,“to prove this king’s a fool not to prove he is a wiser!” So they came up with a plan that would surely not fail.It indeed was a test to make the others look pale.They ordered the queen’s craftsmen(工匠) to make ninety-nine flowers,fake(假的)through and through,but looking so real.When they are finished,even the queen could not tell they were fake.She was sure the king would make the very same mistake.And then from the king’s garden,she took just one real flower,and cleverly hid it among all the others.?注意:
1.所续写短文的词数应为150左右;
2.应使用5个以上短文中标有下划线的关键词语;
3.续写部分分为两段,每段的开头语已为你写好;
4.续写完成后,请用下划线标出你所使用的关键词语。
Paragraph 1:
The king,not wanting to be fooled by this queen,accepted the challenge.?
Paragraph 2:
The tiny bee quickly flew over the flowers and in no time at all found the real flower.?写作思路
一、细读原文,明确篇章结构,确定续写主题。
首先研读原文,确定文章的主题,明确篇章结构。阅读时,关注文中画线的关键词,标记描述事件发展过程的词和短语。对关键词进行分类,为我们理清文章脉络,进行合理故事想象提供有效线索。
本文是一篇记叙文,叙述了一位国王放走了一只蜜蜂,蜜蜂说,以后会报答国王的。后来,国王遇到了困难,得到了蜜蜂的帮助。
二、剖析段首开头语,推断续写情节,把关键词分类。
仔细阅读给出段落的开头语,明确其中所包含的信息并将其延伸,推断出要写的情节。续写段中应包含两部分:一部分沿用所给材料中表示四要素的关键词,一部分是自己通过合理想象新发展的关键词。关键词分类为:
地点:the king’s beautiful palace
人物:a tiny bee,the people of the kingdom,the queen,the craftsmen
事件:on your way,wisdom,plan,mistake,real flower第一段的开头语The king,not wanting to be fooled by this queen,accepted the challenge.提供的信息是国王不想被皇后愚弄,接受了挑战。给出的关键词是:the queen,the people of the kingdom,a tiny bee,real flower,the king’s beautiful palace,the craftsmen,on your way,wisdom,plan,mistake。皇后,王国里的人们,小蜜蜂,真花……把这些关键词串联在一起,那就是国王和皇后的比赛开始了,王国里的人们都期盼看到比赛结果。聪明的国王想尽办法来克服这个困难。就在这时,小蜜蜂出现了,想帮助国王找到真花。国王别无选择,把蜜蜂带到了那些花前。
第二段的开头语The tiny bee quickly flew over the flowers and in no time at all found the real flower.提供的信息是,小蜜蜂立刻在花上面飞来飞去,很快找到了真花。给出的关键词the queen,craftsmen,the king,the tiny bee等。结合上文故事情节,串联关键词,这段的意思就是:蜜蜂找到真花后,国王把真花放到了皇后面前,皇后和工匠们都感叹国王的智慧,并问国王找到真花的办法。国王内心明白,那是蜜蜂的功劳。三、串联情节,增加细节描写,恰当使用衔接词。
把上一步中推断的情节进行串联,增加细节描写(内心情感、态度、表情描述),从而形成完整的段落。串联时要注意选用合适的衔接词,根据题目要求,使用5个以上短文中标有下划线的关键词。
四、润色文字,修改提升,增加语篇亮点。
初稿完成后,要对续写段进行润色,即对其中的用词和句式进行提升修改。提升后的段落语言要新颖,短语优先,善用形容词和副词等修饰词。
五、检查修改,排查错误,确保段落完整。
读后续写检查的重点是一致性和完整性。通读所给材料和自己续写的内容,首先确保不出现与原材料相矛盾的地方,又要做到内容上前后连贯,语句通顺。此外,还要检查有无拼写错误、标点符号错误、大小写错误等,检查词数及画线词是否符合要求。范文赏读

Famous Chinese agricultural scientist Yuan Longping and his research team’s experiment of planting saltwater-tolerant rice in desert areas of Dubai (迪拜)in the United Arab Emirates proved to be a success,with one type of rice producing more than 7.5 tons per hectare(公顷),Xinhua reported.Saltwater-tolerant rice is designed to grow in tidal flats(潮滩地) or other areas with heavy salt content.It was the world’s first successful case of planting rice in a tropical desert area,standing as China’s contribution to improving the ability of people in desert areas to be self-sufficient(自给自足的) in main foods,a move that can protect global food security and improve the desert ecological environment.
In January,the center chose dozens of types of hybrid rice and planted them on small places of desert areas near Dubai.After five months of growth,the center invited experts from India,Egypt,the United Arab Emirates and other countries for evaluation,and found three types of rice producing more than 6 tons per hectare.In June,a second evaluation will be carried out for middle-season rice.The technology of saltwater-tolerant rice plays a key role in the success as the natural environment of the Dubai desert is terrible for rice growth.The daytime temperatures could be as high as over 50℃,and nighttime temperatures could drop by 30℃.Humidity(湿度) stays below 20 percent and there are sandstorms from time to time.The biggest challenge is the desert soil,which is low in organic matter and unable to keep soil moisture as it is totally sand.To make it worse,sea water remains just 7.5 meters below the soil,which makes it easy to be full of salt.
With this success,the center and the private investment office of the ruler of the Emirate of Dubai plan to set up a 100-hectare experimental farmland in Dubai,to test the production costs and cultivation techniques(耕种技术) of the saltwater-tolerant rice and prepare for promotion.The two parties will construct a 100-hectare standard farmland in 2019 and speed up rice planting in 2020.理解诱思
1.What can we infer from the second paragraph?
2.What’s the most difficult thing for rice growth in Dubai desert?
3.What’s the passage mainly about?
答案:1.Chinese team play a great role in planting saltwater-tolerant rice in desert areas.
2.Its soil is short of organic matter and hard to keep soil moisture.
3.Chinese team succeeds in planting saltwater-tolerant rice in Dubai’s desert.
