11、。 自主翻译然而，他最担忧的是农民们的收成不好，有时甚至口粮严重短缺。2句式分析本句中After graduating in 1953可以改写为After he graduated in 1953；从句的谓语动词graduate与主语之间为主动关系。自主翻译1953年大学毕业以后，他成了一名科研人员。3句式分析本句为it 作形式主语的复合句。真正的主语是that引导的从句，而真正的主语太长，为了避免句子头重脚轻，所以用形式主语it。 自主翻译据估计，现在中国国内消费的大米有大约60%来自袁隆平的杂交水稻，他的杂交水稻让中国农民每年能够生产大约两亿吨大米。4句式分析本句中Given that.为
12、连词，相当于considering，意为“考虑到；鉴于”。自主翻译考虑到杂交水稻让袁隆平变得相当富有，人们可能认为他会退休享受闲适的生活。板块二-拓展训练.阅读理解AThree experimental fields of seawater rice were harvested in China on Wednesday，a further step toward its future practical use.Also known as salinealkali tolerant rice(耐盐碱水稻)，the seawater rice is designed to grow in s
13、easide flats or other areas with high salt content and has been developed by experts through crossbreeding(杂交) and other technologies.One type of seawater rice growing in Qingdaos Chengyang district，Shandong Province，produced 3.9 metric tons(公吨) per hectare(公顷)，experts announced.Once widely planted
14、in large areas，the output could be much higher.The Qingdao SalineAlkali Tolerant Rice Research and Development Center，led by renowned Chinese agricultural scientist Yuan Longping，was established several years ago.It set itself a threeyear target of developing a kind of saltresistant rice capable of
15、producing 4.5 tons a hectare，which would guarantee growers the minimum acceptable level of profit.The average rice output in China is 6.75 tons a hectare.Planting in the experimental field in Chengyang district and five other plots of salinealkali land started at the end of May.The five other plots
16、were in Dongying，Shandong Province；Wenzhou，Zhejiang Province；Yanan，Shaanxi Province；Kashgar，the Xinjiang Uygur Autonomous Region；and Daqing，Heilongjiang Province.The sites represent actually every type of salinealkali land in China and researchers aim to grow different kinds of rice able to cope wit
17、h different climate，salinity and soil structure conditions.The test crops in Kashgar and Daqing were also harvested on Wednesday.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
18、it is possible to plant such saltresistant rice in southern Xinjiang in the future.Xinjiang has about 2 million hectares of salinealkali land that have the potential to be planted with saltresistant rice，and if it is widely planted it will generally improve rice production in the region.The seawater
19、 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 extremel

D7.5 tons a hectare.3The researchers chose the experimental fields according to .Athe distance between themBthe type of the soil and climateCthe local governments supportDthe local agricultural conditions4What can we infer about the sea
22、water rice from the last paragraph?AThe seawater rice is not fit for all kinds of salinealkali soils.BIt is impossible for the seawater rice to have a good harvest.CGrowers from Shandong Province were a little disappointed by the result.DThe output of the seawater rice grown in Daqing is the lowest.
23、答案CBBABIt used to be mostly the military(军队) that used small，unpiloted aircraft，called “drones”The little planes were very costly.But as they have dropped in price more people have begun to use them.Rescue workers and farmers are among the new users.Moviemakers are using drones to film from the sky.
24、Historians use them when they explore ancient buildings.Rescue workers use them to look for people.And now farmers are using them to watch over their crops.Romain Faroux is a French businessman who starts companies.His father was a farmer.He believed drones could help farmers.He helped create a comp
25、any that developed a small drone that could be controlled by people on the ground.They called it “Agridrone”It uses a special “optical sensor” to examine crops.He says the technology used is similar to that used by smartphonesexcept it has wings.A computer program directs the drone to fly over the c
26、rops.The sensor on the drone records four differentcolored “bands” of sunlight that are reflected off the crops.JeanBaptiste Bruggeman is a farmer.He says the drone flies over his crops at different times of the season.And this provides a lot of information about his crops.The drone pictures show hi
27、m the exact amount of fertilizer the crops need.It also shows exactly where the fertilizer is needed.Some areas of a field may need more than others.As a result，Mr Bruggeman says there is reduced nitrogen from the fertilizer after the harvest.This helps nature.Romain Faroux says farmers use informat
28、ion gathered by the Agridrone to place fertilizer only in areas where it was needed.Before they used the drones，farmers would put the same amount of fertilizer everywhere.Drones also save time because farmers can examine up to three hectares in about a minute.5The first paragraph is mainly about .At
29、he expensive cost of dronesBthe fast development of dronesCthe wide use of dronesDthe urgent need of drones6What do we know about Agridrone?AIt records differentcolored bands of sunlight.BIt flies over the crops with a computer.CIt absorbs the sunlight reflected off the crops.DIt is like a smartphon
30、e with wings.7What Mr Bruggeman said implied that by using drones .Ahe saved money and reduced pollutionBhe could gather his crops easilyChe could fly over his crops at different timesDhe knew exactly the ingredients of his fertilizer8What is the main idea of the passage?ADrones will be widely used
31、in different fields.BFrench farmers use drones to examine their crops.CCrops will be harvested by drones soon.DFarmers develop special drones for their crops.答案CDABCWhen Im in Italy，I generally only eat Italian food.I doubt whether theres another country in Europe that has food that can keep me comi
32、ng back for more.To eat well in Italy，finding the right restaurant is essential.I appreciate personalitydriven restaurants，run by people keen(热衷的) to share their love of good cooking，and places serving family recipes.Signs of a good restaurant include a lowrent location，lots of locals，and a small，ha
