7、nant. 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
8、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,
9、 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
10、 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(长期的)mental effort, such as homework or games with
11、 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 h
12、eating 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 p

17、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 improv
18、e 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
19、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)“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
20、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,
21、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 im
22、prove document search.”4)The researchers designed and tested a machine vision systema 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. This informationg is used to enrich the d
23、escription 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 ad
24、ditional 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.【题干】Paragraph 1 _【选项】A.Popularity of the new systemB.Publication of the new discovery
