increased of attention problems,seen as early as grade school.If their noses inhaled(吸入)a certain type of air pollution when they were pregnant.Thats the finding of a new study.Released when things arent burned completely,this pollution is known as polycyclic aromatic hydrocarbons,or PAHs.The biggest sources of these PAHs: the burning of fossil fuels,wood and trash.Frederica Perera works at Columbia Universitys Mailman School of Public Health is New York City.She researches how exposure to things in the environment affects childrens health in a new study,she and her team studied the exposure to air pollution of 233 nonsmoking pregnant women in New York City.Because burning tobacco can spew(排放)PAHs into the air and lungs,Pereras team focused on nonsmokers.The researchers wanted to probe(探查)other sources of PAHs,ones thats would have been hard for an individual to avoid.The team started by testing the blood of each woman during pregnancy.The reason Any PAHs in a womans blood would also be available to the baby in her womb.Nine years later,the researchers investigated signs of attention problems in those children,now age 9.They asked each childs mother a series of questions.These included whatever her child had problems doing things that needed sustained(长期)mental effort,such as homework or games with friends.The scientists also asked if the kids had trouble following instructions or made frequent,careless mistakes.All of these can be symptoms of a disorder called Attention Deficit Hyperactivity Disorder,or ADHD.About one in U.S.children has ADHD.Among the women studied,traffic and home heating were the primary sources of air pollution exposure,Perera and her team suspect.Some of these women had low levels of PAHs in their blood.Ohters had high levels.Those with high levels were five times as likely to have children who showed attention problems by age 9.The new findings were published November 5 in the journal PLOS ONE.16.Perera and her team chose nonsmoking pregnant women all over America.A.RightB.WrongC.Not mentioned参照答案:B17.The main purpose of the research was to find out how exposure to PAHs played a role in harming the subjectsphysical health.A.RightB.WrongC.Not mentioned参照答案:B18.Nonsmoking mothers were selected because the effect of smoking on PAHs was unclear.A.RightB.WrongC.Not mentioned参照答案:B19.The blood of each woman was tested once a month during pregnancy.A.RightB.WrongC.Not mentioned参照答案:C20.Kids with ADHD commonly fail in school.A.RightB.WrongC.Not mentioned参照答案:C21.The women with high levels of PAHs in their blood were more likely to have kids with ADHD.A.RightB.WrongC.Not mentioned参照答案:A22.Traffic and home heating were considered to be the biggest sources of PAHs for the subjects in the research.A.RightB.WrongC.Not mentioned参照答案:A第三某些:概括大意与完毕句子下面短文后有2项测试任务:(1)第2326题规定从所给6个选项中为指定段落每段选取1个标题;(2)第2730题规定从所给6个选项中为每个句子拟定一种最佳选项。(第2330题,每题1分,共8分)First Image-recognitions software1)Dartmouth researchers and their colleagues have created an artificial intelligence software that uses photos to locate documents on the Internet with far greater accuracy than ever before.2)The new system,witch was tested on photos and is now being applied to videos,shows for the first time that a machine learning algorithm(运算法则)for image recognition and retrieval is accurate and efficienti enough to improve large-scale document searches online.The system uses pixel(像素)data in images and potentially videorather than just textto locate documents.It learns to recognize the pixels associatedwith a search phrase by studying the results from text-based image search engines.The knowledge gleaned(收集)from those results can then be applied to other photos without tags or captions(图片阐明),making for more accurate document search results.3)Over the last 30 years,says Associate Professor Korenzo Torresani,a co-author of the study,the web has evolved from a small collection of mostly text documents to a modern,massive,fast-growing multimedia datastet,where nearly every page includes multiple pictures of videos.When a person looks at a Web page,he immediately get the gist(主旨)of it by looking at the pictures in it.Yet,sruprisingly,all existing popular search engine,such as Google or Bing,strip away the information contained in the photos and use exclusively the text of Wed pages to perform the document retrieval.Our study is the first to show that modern machine vision systems are accurate and efficient enough to make effective use of the information contained in image pixels to improve document search4)The researchers designed and tested a machine vision systema type of artificialintelligence that allows computers to learn without being explicitly programmedthat extracts semantic(语义)information from pixels of photos in Web pages.This informationg is used to enrich the description of the HTML page used by search engines for document retrieval.The researchers tested their approach using more than 600 search queries(查询)on a database of 50 million Wed pages.They selected the text-retrieval search engine with the best performance and modified it to make use of the additional semantic information extracted by their method from the pictures of the Web pages.They found tht this produced a 30 percent improvement in precision over the original search engine purely based on text.23.Paragraph 1 _A.Popularity of the new systemB.Publication of the new discoveryC.Function of the new systemD.Artificial intelligence software createdE.Problems of the existing search

health of the coffee drinker.Is it food for your heart? Does it increase blood pressure? Does it help you concentrate? However,coffee affects the health of the human population in other ways,too.Traditionally,coffee bushes were planted under the canopy(树冠)of taller indigenous(土生土长)trees.However,more and more farmers in Latin America are deforesting the land to grow full-sun coffees.At first,this increases production because more coffee bushes can be planted if there arent any trees.With increased production come increased profits.Unfortunately,deforesting for coffee production immediately decreases local-wildlife habitat.Native birds nest and hide from predators(捕食者)in the tall trees and migrating birds rest there.Furthermore,in the long term,the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides are needed to grow the coffee.The fertilizers and pesticides kill insects that eat coffee plant,but then the birds eat the poisoned insects and also die.The chemicals kill or sicken other animals as well,and can even enter the water that people will eventually drink.Fortunately,farmers in Central and South America are beginning to grow more coffee bushes in the shade.We can support these farmers by buying coffee with such labels as shade grownand bird friendly.Sure,these varieties might cost a little more.But were paying for the health of the birds,the land,ourselves,and the planet.I think its worth it.31.What is the main idea of this passage?A.Farmers are changing the way they grow coffee.B.Coffee is becoming more expensive to produce.C.Shade-grow coffee is more expensive than sun-grow coffee.D.People should buy shade-grown coffee.参照答案:A32.The function of the word Traditionallyin Paragraph 2 is to show_.A.the positive effects of coffee.B.a change of coffee growth.C.something that is the most important.D.how coffee production used to be.参照答案:B33.What does increased production of full-sun coffee bring about?A.More insects.B.Better quality coffee.C.Larger farms.D.Higher profits.参照答案:D34.How do farmers find more land for growing full-sun coffee?A.They buy more land from other farmers.B.They cut down trees.C.They move to another country.D.They turn grassland into farmland.参照答案:B35.The full-sun method may affect the following EXCEPT_.A.insects.B.air.C.brids.D.humans.参照答案:B第二篇:More Rural Research is NeededAgricultural research funding is vital if the world is to feed itself better than it does now.Dr.Tony Fischer,crop scientist,said demand was growing at 2.5% per year but with modern technologies and the development of new ones,the world should be able to stay ahead.The global decline in investment in international agricultural research must be reversed if significant progress is to be made towards reducing malnutrition(营养不良)and poverty.he said.Research is needed to solve food production,land degradation(贫瘠化)and environmental problems.Secure local food supplies led to economic growth which is turn,slowed population growth.Dr.Fischer painted a picture of the worlds ability to feed itself in the first 25 years,when the worlds population is expected to rise from 5 X to X billion people.He said that things will probably hold or improve but therell still be a lot of hungry people.The biggest concentration of poor and hungry people would be in sub-Saharan Africa and southern Asia in ,similar to the currenti pattern.If there is any change,a slighe improvement will be seen in southern Asia,but not in sub-Saharan Africa.The major improvement will be in East Asia,South America and South-East Asia.The debeloping world was investing about 0.5%,or $8 billion a year,of its agricultural gross domestic product(GDP)on research and developed world was spending 2.5% of its GDP.Dr.Fischer said more was needed from all countries.He said crop research could produce technologies that spread across many countries,such as wheat production research having spin-offs(有用副产品)for Mexico,China or India.Technologies still need to be refined for the local conditions but a lot of the strategic research can have global application,so that money can be used very efficiently.Dr.Fischer said.Yields of rice,wheat ad maize(玉米)have grown impressively in the past 30 years,especially in developing countries.For example,maize production rose from 2 to 8 tonnes per hectare between 1950 and 1995.But technologies driving this growth such as high-yield varieties,fertilizers,and irrigation,were becoming exhausted.If you want to save the land for non-agricultural activities,for forests and wildlife,youre going to have to increase yield.Dr.Fischer said.36.What is the passage mainly about?A.Shortage of food supplies.B.Development of agricultural technologies.C.Impact of agricultural research.D.Expectation of population growth.参照答案:C37.Which of the following statements is true about the worlds agricultural research funding?A.It is increasing among developed countries.B.It is decreasing worldwide.C.Less is demanded from developing countries.D.Most of it is spent very efficiently.参照答案:B38.What is the picture of Asias food supplies in the first 25 years?A.Food shortage will not be a problem.B.There will be more hungry people in southern Asia.C.Population growth will result in more hungry people.D.There will be fewer hungry people in East Asia.参照答案:C39.What does Dr.Fischer say about technologies?
