下面的短文后列出了7个句子，请根据短文的内容对每个句子作出判断：如果该句提供的是正确信息，请选择A;如果该句提供的是错误信息，请选择B;如果该句的信息文中没有提及，请选择C.(第16—22题，每题1分，共7分) ADHD Linked to Air Pollutants
Children have an 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.That's the finding of a new study.Released when things aren't burned completely,this pollution is known as polycyclic aromatic hydrocarbons,orPAHs.The biggest sources of these PAHs：the burning of fossil fuels,wood and trash.
Frederica Perera works at Columbia University's Mailman School of Public Health is New York City.She researches how exposure to things in the environment affects children's 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,Perera's team focused on nonsmokers.The researchers wanted to probe(探查)other sources of PAHs,ones that's 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 woman's 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 child's mother a series of questions.These included whatever her child had problems doing things that needed sustained(长期的)mental effort,such as homework or games with friends.The scientists also asked if the kids had trouble following instructions or made frequent,carelessmistakes.All of these can be symptoms of a disorder called Attention Deficit Hyperactivity Disorder,orADHD.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.Right B.Wrong
C.Not mentioned 参考答案：B
17.The main purpose of the research was to find out how exposure to PAHs played a role in harming the subjects'physical health. A.Right B.Wrong
C.Not mentioned 参考答案：B
18.Nonsmoking mothers were selected because the effect of smoking on PAHs was unclear. A.Right B.Wrong
C.Not mentioned
参考答案：B
19.The blood of each woman was tested once a month during pregnancy. A.Right B.Wrong
C.Not mentioned
参考答案：C
20.Kids with ADHD commonly fail in school. A.Right B.Wrong

参考答案：C
21.The women with high levels of PAHs in their blood were more likely to have kids with ADHD. A.Right B.Wrong
C.Not mentioned 参考答案：A
22.Traffic and home heating were considered to be the biggest sources of PAHs for the subjects in the research. A.Right B.Wrong

第三部分：概括大意与完成句子
下面的短文后有2项测试任务：(1)第23—26题要求从所给的6个选项中为指定段落每段选择1个标题;(2)第27—30题要求从所给的6个选项中为每个句子确定一个最佳选项。(第23—30题，每题1分，共8分) First Image-recognitions software
1)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 video—rather than just text—to 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(图片说明)，making for more accurate document search results.
3)\the last 30 years,\Associate Professor KorenzoTorresani,a co-author of the study,\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.Whena 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 search\
4)The researchers designed and tested a machine vision system—a type of artificialintelligence that allows computers to learn without being explicitly programmed—that extracts semantic(语义的)information from pixels of photos in Web pages.Thisinformationg 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 system B.Publication of the new discovery C.Function of the new system
D.Artificial intelligence software created E.Problems of the existing search engines F.Improvementi in document retrieval 参考答案：D
24.Paragraph 2 _____
A.Popularity of the new system B.Publication of the new discovery C.Function of the new system
D.Artificial intelligence software created E.Problems of the existing search engines F.Improvementi in document retrieval 参考答案：C
25.Paragraph 3 _____
A.Popularity of the new system B.Publication of the new discovery C.Function of the new system
D.Artificial intelligence software created E.Problems of the existing search engines F.Improvementi in document retrieval 参考答案：E
26.Paragraph 4 _____
A.Popularity of the new system B.Publication of the new discovery C.Function of the new system
D.Artificial intelligence software created
