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, th
7、is 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
8、 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
9、 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
10、 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 friends. The scientists also asked if the kids had trouble following instructions or ma

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.
12、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 pre

17、val is accurate and efficient 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 associated with a search phrase by studying the results from text-based image
18、 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)“Over the last 30 years,” says Associate Professor Korenzo Torresani, a co-author of the study,” the web has evolved from
19、 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, surprisingly, all existing

Our study is the first to show that modern machine vision systems are accurate and efficient enough to make effective use of
21、 the information contained in image pixels to improve 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
22、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 p

Is it food for your heart? Does it increase blood pressure? Does it help you concentrate? However
27、, 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(土生土长的)trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees. At first, this increases productio
28、n 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 re
29、st 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 chem
30、icals 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 grown and bird f
31、riendly. 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
32、. Shade-grow coffee is more expensive than sun-grow coffee.D. People should buy shade-grown coffee.32. The function of the word Traditionally in 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 use
33、d to be.33.What does increased production of full-sun coffee bring about?A. More insects.B. Better quality coffee.C. Larger farms.D. Higher profits.34. 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 co
34、untry.D. They turn grassland into farmland.35.The full-sun method may affect the following EXCEPT_ full sunA. insects.B. air.C. birdsD. humans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 scientis
35、t, 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 malnutriti
36、on(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 ye
37、ars, 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 2020, similar to th
38、e current pattern. If there is any change, a slight 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 developing world was investing about 0.5%, or $8 billion a year, of its agricultural gross d
39、omestic 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(有用的副产品)for Mexico, China or Ind
40、ia.“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)havegrown impressively in the past 30 years, especially in developing co
41、untries. 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 wi
42、ldlife, 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.37. Which of the following statements is true about th
43、e 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.38. What is the picture of Asias food supplies in the first 25 years?A. Food shortage will not be a
44、 problemB. 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.39. What does Dr. Fischer say about technologies? Dr FischerA. They are costly.B. They have to be improved to meet local needs.C. Thei
45、r application is limited.D. They have to be applied locally.40. It can be infered from the last paragraph that_.A. there is a demand for saving land for non-agricultural activities.B. crop production is growing faster in developing countries.C. maize production reached its peak in the 1990s.D. techn
46、ologies improving maize production have been well developed.第三篇Dangers await babies with altitudeWomen who live in the worlds highest communities tend to give birth to under-weight babies, a new study suggests. These babies may grow into adults with a high risk of heart disease and strokes.Research
47、has hinted that newborns in mountain communities are lighter than average. But it wasnt clear whether this is due to reduced oxygen levels at high altitude or because their mothers are under-nourished many people who live at high altitudes are relatively poor compared with those living lower down.To find out more, Dino Giussani and his team at Cambridge University studied the records of 400 births in Bolivia during 1976 and 1998. The babies were born in both rich and poor areas
