13.Agricultural experts met in Ethiopia last week to discuss ways to help sub-Saharan Africa become a major producer of wheat.The area traditionally produced little wheat,while North Africa was the grain basket.
Wheat production fell sharply in sub-Saharan countries during the 1980s.In the 1960s,attempts were made to grow wheat in sub-Saharan Africa,including South Africa and Zimbabwe.But those countries found it was less costly to import wheat from Europe and the United States.Another problem is that Africa's wheat farms were often far from population centers.There also were transportation issues.And some lowlands were not a good place to grow wheat.
Hans Joachim Braun,one of the experts,says now is a good time to increase wheat production.In the last four years we have seen three major price hikes,where the wheat price and other staple process (主食加工)exploded.And that puts a big,big bill on countries which are depending on wheat imports,and Africa is the biggest wheat importer.
He also says demand for wheat in sub-Saharan Africa is growing faster than for any other crop.With higher income people would like to have more diversified(多样化)food.But that is possible not the most important one.The most important one is that there is a tremendous migration(移民)of in particular male labor to the cities.And wheat products are convenient food because you can easily buy it.It's easy to process and you also can store it for a few days,which is different from some of the maize and rice products.
There are three possible challenges for growing more wheat in Africa:climate change,disease and pests,like insects.Mr.Braun says rising temperatures should not have a major effect on wheat.In fact,he says,it could help wheat grow in areas with high rainfall totals.As for fighting disease and pests,experts suggest growing more resistant crops.In addition,railroads and roads would have to be improved so large amounts of wheat could be moved to large markets.

39.What does the word"hikes"in Paragraph 3probably refer to?B
A.big changes 
B.large increases 
C.long trips 
D.big bills
40.Wheat price exploding indicatesA.
A.sub-Saharan countries need to increase wheat production badly
B.sub-Saharan countries have to issue more money
C.sub-Saharan countries should grow more Corn
D.importing much wheat is urgent
41.Why is there a higher demand for wheat in sub-Saharan Africa?C
A.Because the number of hungry people there is increasing.
B.Because higher income people have the diversified need of food.
C.Because male labor are crowding into the cities.
D.Because the wheat price is lower.
42.According to Mr.Braun the main challenges for growing more wheat in Africa areD.
A.climate change and disease
B.resistant crops and climate change
C.rising temperatures and disease and pests
D.disease and pests and inconvenient transportation.

分析 农业专家上一周在埃塞尔比亚会面讨论帮助次撒哈拉沙漠地区的非洲成为一个小麦主产区.这一地区传统上生产的小麦很少而北非曾经是谷类粮仓.次撒哈拉国家的小麦产量锐减.一方面从欧洲和美国进口小麦费用更少;另一方面非洲的农场离人口中心区很远,运输是个问题,还有一些低洼地区不宜种小麦.现在是时候增加小麦生产了.在四年的时间里小麦价格就暴涨了三次.进口小麦费用就会大大增加.到了自己生产小麦的时候了.

解答 39.B.词意猜测题.hikes是熟词新意,原意是爬山,在这里是价格上的"爬山",结合后面的where the wheat price and other staple process (主食加工)exploded.(小麦价格和其他主食加工的暴涨.)判断.故选B.
40.A.推理判断题.文章第二段的大意:次撒哈拉国家的小麦产量锐减.一方面从欧洲和美国进口小麦费用更少;另一方面非洲的农场离人口中心区很远,运输是个问题,还有一些低洼地区不宜种小麦.现在是时候增加小麦生产了.下一段开头提到:在四年的时间里小麦价格就暴涨了三次.进口小麦费用就会大大增加.故选A.
41.C.细节理解题.文章第四段提到:一方面收入提高了,人民想要食物的多样化;更重要的是有大量的人员尤其是男劳动力移民到城市;还有小麦产品方便购买、加工和储存.再分析四个选项判断,最佳选C.故选C.
42.D.细节理解题.文章最后一段提到:在影响小麦生产的三个主要原因中,Mr.Braun说:气温上升不应该对小麦有主要影响.在降雨量大的地区这还有助于小麦的生长.至于疾病和病虫害,专家建议多种抗虫小麦.另外铁路和道路必须要改善这样大量的小麦才有可能被运到大市场去.故选D.

点评 本文是新闻报道类阅读理解文章,阅读此类文章主要是要了解:
①新闻报道了什么事件;②事件是因为什么而发生的,相关背景如何;③文段中指出的事件发生过程中的突出细节是 什么;④事件造成的后果是什么;⑤事件的本质是什么,透过事件的表面现象,我们看到了什么社会问题.通过这样的梳理,我们就可以把新闻的脉络理清楚.这类材料命题点往往落在事实细节上.

18.1.The country of Chile is struggling to recover from one of the most powerful earthquakes in history.The quake struck the South American nation early Saturday morning.It registered 8.8on the Richter scale.Experts say the earthquake in Chile is among the five most powerful earthquakes ever recorded.
2.The epicenter of the earthquake is about 70miles north of the city of Concepcion.The area has been rocked by dozens of aftershocks since the big  quake hit on Saturday morning.
3.On Sunday,Chilean President Michelle Bachelet updated re-ports on the toll the earthquake has taken.‘It's an enormous ca-tastrophe,'she said.Countless buildings and roadways have been destroyed or badly damaged.Rescuers continued to work around the clock to find survivors who may be trapped under the rubble of fallen buildings.Countless buildings and roadways have been destroyed or badly damaged.Rescuers continued to work around the clock to find survivors who may be trapped under the rubble of fallen buildings.Government officials estimate more than 2million people have lost their homes.
4.Bachelet assured people that food and medical aid were on the way.Ten thousand members of the Chilean military have been dispatched to help in the relief and recovery efforts.Many of the country's major grocery stores have started giving away basic food and supplies to people in the affected areas.Secretary-General of the United Nations spoke to President Bachelet by telephone.He assured her that the United Nations‘stands ready to assist the Chilean government's rescue and recovery efforts'.
5.The earthquake in Chile comes less than two months after the 7.0magnitude earthquake that Haiti suffered in January.Al-though the earthquake in Chile was more powerful than the one in Haiti,the damage is unlikely to be as severe.Earthquakes are more common in Chile,and many buildings and homes there are constructed to withstand tremors better.Also,the area of Chile most affected by this earthquake is not as heavily populated as Port-au-Prince,where the epicenter of the Haitian quake was lo-cated.Furthermore,Chile is one of South America's richest,best-organized countries.Its government has more supplies and people available to effectively respond to national emergencies.
6.The energy released by the quake caused shock waves to roll across the Pacific Pcean in the form of tsunamis(海啸) that have the potential to do great damage to coastal areas.Some of these waves struck the Chilean coast,causing major damage to seaside towns.Coastal commuities in Russia,Ja-pan,and the United States were concerned,too,but there were no reports of severe damage from the waves that eventually reached the countries'shores.

57.Who is leading the earthquake relief efforts in Chile?A
A.The Chilean government and military.
B.Geologists and other scientists.
C.The United Nations peacekeeping forces.
D.Secretary-General of the United Nations.
58.The damage from Chile's earthquake is not expeeted to be as severe as the damage from Haiti's quake.Which could not be the reason for it?B
A.Chile is one of the richest,best-organized countries in South America.
B.Chile has constructed many buildings for the people.

B.massive waves in the Pacific Pcean
C.a lack of food supplies in coastal communities
D.a social confusion across the globe

5.Millions of sports lovers are sill thinking about one thing----the Winter Olympics in Sochi Russia.close to 2900 men and women competed in the 2014 Winter Games about a month ago.
The Olympics brought a lot of attention to Sochi,a city on the black Sea,which is a popular area for vacation travelers.The area is known for its mild winters,with warm to summer.
At least 50 billion was spent on the 2014 Winter Games,making it the costliest Olympics in history.Seven billion dollars was spent on the 2010 Winter Games in Vancouver,Canada.Olympic officials chose Sochi to host the 2014 games almost seven years ago,At that time,Russian President Vladimir Putin said the games would cost about   13 billion.Yet times his estimate.So where did all the money go?
    Some observers say the high cost is partly the result of security measures.Brian Jenkins,a terrorism expert from the RAND Corporation,gave the following explanation.'There were anywhere between 70,000 and 100,000 policemen and military troops deployed around the city.
    The main threat came from separatist and Islamist groups from the North Caucasus,especially from Chechnya and Dagestan.One group claimed responsibility for two suicide bombings in Volgograd last December.The attacks killed more than 30 people.The city is only about 600 kilometers away from Sochi.
    Bruce Hoffman is a terrorism export from Georgetown University in Washington DC.He says the increased security made Sochi a difficult target for terrorists.
    It is thought that the terrorists'intention was to make life difficult for the Russians and to create some sort of incident that would take away the enjoyment.
The last Olympians from around the world on Russian soil was in 1980.That was a year after Soviet troops invaded Afghanistan.More than sixty countries didn't take part in the Moscow Summer Games to show their anger.
