Most people are aware that outdoor air pollution can damage their health,but many do not know that indoor air pollution can also have significant health effects.Environmental Protection Agency studies indicate that indoor levels of pollutants may be 3~5 times,and occasionally more than 100 times,higher than outdoor levels.These levels of indoor air pollutants may be of particular concern because most people spend about 90% of their time indoors.
There are many sources of indoor air pollution in any home.These include sources such as oil,gas,coal,wood,and tobacco products,building materials,wet or damp carpet,and furniture made of certain pressed wood products,products for household cleaning and maintenance,personal care,or hobbies,central heating and cooling systems.
Immediate effects may show up after a single exposure (暴露) or repeated exposures.These include irritation of the eyes,nose,and throat,headaches,dizziness.Such immediate effects are usually short­term and treatable.Sometimes the treatment is simply removing the person’s exposure to the source of the pollution,if it can be identified.
The likelihood of immediate reactions to indoor air pollutants depends on several factors.Age and pre­existing medical conditions are two important influences.In other cases,whether a person reacts to a pollutant depends on individual sensitivity,which varies tremendously from person to person.Some people can become sensitized to biological pollutants after repeated exposures,and it appears that some people can become sensitized to chemical pollutants as well.
Certain immediate effects are similar to those from colds or other viral (病毒性的) diseases,so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution.While pollutants commonly found in indoor air are responsible for many harmful effects,there is considerable uncertainty about what concentrations or periods of exposure are necessary to produce specific health problems.People also react very differently to exposure to indoor air pollutants.Therefore,further research is needed to better understand the effects of indoor air pollution and to find efficient ways to protect our health.

Boiler rooms are often dirty and steamy,but this one is clean and cool.Fox Point is a very new 47­unit living building in South Bronx,one of the city’s poorest areas.Two­thirds of the people living there are formerly (以前) homeless people,whose rent is paid by the government.The rest are low­income families.The boiler room has special equipment,which produces energy for electricity and heat.It reuses heat that would otherwise be lost to the air,reducing carbon emissions(碳排放)while also cutting costs.
Fox Point is operated by Palladia,a group that specializes in providing housing and services to needy people.Palladia received support from Enterprise Community Partners (ECP),which helps build affordable housing by providing support to housing developers.
ECP has created national standards for healthy,environmentally (環(huán)境方面) clever and affordable homes which are called the Green Communities Standards.These standards include water keeping,energy saving and the use of environmentally friendly building materials.Meeting the standards increases housing construction costs by 2%,which is rapidly paid back by lower running costs.Even the positioning of a window to get most daylight can help save energy.
Michael Bloomberg,New York’s mayor,plans to create 165,000 affordable housing units for 500,000 New Yorkers.Almost 80% of New York City’s greenhouse gas emissions come from buildings,and 40% of those are caused by housing.So he recently announced that the city’s Department of Housing and Preservation and Development (DHPD),whose duty is to develop and keep the city’s supply of affordable housing,will require all its new projects to follow ECP’s green standards.
Similar measures have been taken by other cities,such as Cleveland and Denver,but New York’s DHPD is the largest city developer of affordable housing in the country.(2010·四川,B)
小題1:What is the purpose of describing the boiler rooms in the first paragraph?
A.To explain the measures the city takes to care for poor people.
B.To suggest that affordable housing is possible in all areas.
C.To show how the environment­friendly building works.
D.To compare old and new boiler rooms.
小題2:What is an advantage of the buildings meeting the Green Communities Standards?
A.Lower running costs.
B.Costing less in construction.
C.Less air to be lost in hot days.
D.Better prices for homeless people.
小題3:It can be learned from the text that________.
A.New York City is seriously polluted
B.people’s daily life causes many carbon emissions in New York City
C.a(chǎn) great number of people in New York City don’t have houses to live in
D.some other cities have developed more affordable housing than New York City
小題4:What is the main purpose of this text?
A.To call on people to pay more attention to housing problems.
B.To prove that some standards are needed for affordable housing.
C.To ask society to help homeless people and low­income families.
D.To introduce healthy,environmentally clever and affordable housing.

I’ve always known my kids use digital communications gear (裝置) a lot.But my cellphone bill last month really grabbed my attention.My son had come up to nearly 2,000 incoming text messages,and had sent nearly as many.Of course,he was out of school for the summer and communicating more with friends from a distance.Nevertheless,he found time to hold down a summer job and complete a college course in between all that typing with his thumb.
I was even more surprised to learn that my son is normal.“Teenagers with cellphones each send and receive 2,272 text messages a month on average,” Nielsen Mobile says.
Some experts regret that all that  keyboard jabber is making our kids stupid,unable to read non­verbal cues such as facial expressions,gestures,posture and other silent signals of mood and attitude.Unlike phones,text messaging doesn’t even allow transmission of tone of voice or pauses,says Mark Bauerlein,author of a book called The Dumbest Generation:How the Digital Age Stupefies Young Americans and Jeopardizes Our Future.
Beyond that,though,I’m not sure I see as much harm as critics of this trend.I’ve posted before on how I initially tried to control my kids’ texting.But over time,I have seen my son suffer no apparent ill effects,and he gains a big benefit,of easy,continuing contact with others.
I don’t think texting make kids stupid.It may make them annoying,when they try to text and talk to you at the same time.And it may make them distracted,when buzzing text messages interrupt efforts to noodle out a math problem or finish reading for school.
But I don’t see texting harming teens’ability to communicate.My son is as accustomed to nonverbal cues as any older members of our family.I have found him more engaged and easier to communicate with from a great distance,because he is constantly available via text message and responds with faithfulness and speed.

Most parents of kids under age 8 don't worry about how much time they spend watching TV or using other media, from computers to smart phones to tablets PCs, according to a new survey that found a child's use of media often reflects how much time parents spend in the similar way.
¨We generally found that media use is not a source of conflict in the home" for families with young children, Ellen Wartella, a researcher from Northwestem University, told USA Today. She led a survey of 2,326 parents who have children 8 and younger.It found that in 80 percent of families, children's media use was not a problem, with 55 percent “not too" or“ not at all"  concerned about it. It also showed parents have more positive than negative feelings about how media consumption affects a child's learning and the development of creativity.The exception is video games, which are viewed more negatively than TV, computers or mobile devices.“Parents rated video games as more likely to have a negative effect on children's school performance, attention time, creativity, social skills, behavior and sleep than any other medium," the researchers said in a news conference about the survey.
¨The findings exposes a generational shift (轉(zhuǎn)移) in parental attitudes about technology's role in young children's lives," said Wartella.“Today's parents grew up with technology as a central pact of their lives, so they think about it differently than earlier generations of parents, instead of a battle with kids on one side and parents on the other, the use of media and technology has become a family affair. "
The researchers identified three media environments created by parents: media-centric (39 percent of families) , media-moderate (45%)and media-light (16%). Children  in media-centric families spend at least three hours more each day watching TV or using computers, video games and tablet PCs don't make parenting easier.And 88 percent of parents say they are most likely to turn to toys or activities to keep their children occupied.Slightly fewer turn to books (79%) and TV(78%).
The survey didn't look at how media affects children. That's a topic that the American Academy of Pediatrics has handled a number of times. The AAP says studies have found too much media use can lead to attention- problems, school difficulties, sleep and eating disorders and being fat. In addition, the Internet and cell phones can provide platforms for illegal and risky behaviors.¨By limiting screen time and offering educational media and non-electronic formats (格式)such as books, newspapers and board games, and watching television with their children, parents can help guide their children's media experience. Putting questionable content into context and teaching kids a700ut advertising contributes to their media literacy (素養(yǎng)) ," it says.
The pediatricians' group says parents should have “screen-free zones"  and TV should be turned off during dinner. At most, it recommends children and teens engage with entertainment media for no more than two hours a day and that should be high-quality content. It is important for kids to spend time on outdoor play, reading, hobbies  and  using their imaginations  in free  play.“ Kids  under 2 should not use television and other entertainment media because their brains are developing quickly and they learn best from direct human interaction," the group says.
An article on screen time by t.he Mayo Clinic also notes problems linked t.o over screen time, including  being  fat, irregular  sleep , behavioral  problems , weak  school  performance , violence  and  less time for active and creative play.
小題1:Parents have more negative than positive feelings about media consumption like    
A.computersB.smart phones
C.video gamesD.tablets PCs
小題2:Most parents don't worry about kid's media use because        
A.they can limit the screen time
B.they want their children happy
C.they also grew up with technology
D.they can teach their children themselves
小題3:From the data of the survey, we learn       
A.children in media-centric families are smarter than others
B.children in media-light families spend one hour watching TV
C.more than half of the parents think children's media use was a problem
D.media-centric children spend more than three hours each day on media use
小題4:To make parenting easier, most parents probably        
A.try to persuade their children to read books
B.a(chǎn)sk their children questions while watching TV
C.a(chǎn)llow their children watching TV or using computers
D.turn to toys or activities to keep their children occupied
小題5:Which of the following is a suggestion by the researchers?
A.Media use time for babies under 2 should be limited.
B.Entertainment media use should be high-quality content.
C.Schools should provide more time for active and creative play.
D.Home media use should provide platforms for illegal and risky behaviors.

  Mass transportation revised the social and economic fabric of the American city in three fundamental ways. It catalyzed physical expansion, it sorted out people and land uses, and it accelerated the inherent instability of urban life. By opening vast areas of unoccupied land for residential expansion, the omnibuses, horse railways, commuter trains, and electric trolleys pulled settled regions outward two to four times more distant form city centers than they were in the premodern era. In 1850, for example, the borders of Boston lay scarcely two miles from the old business district; by the turn of the century the radius extended ten miles. Now those who could afford it could live far removed from the old city center and still commute there for work, shopping, and entertainment. The new accessibility of land around the periphery of almost every major city sparked an explosion of real estate development and fueled what we now know as urban sprawl. Between 1890 and 1920, for example, some 250,000 new residential lots were recorded within the borders of Chicago, most of them located in outlying areas. Over the same period, another 550,000 were plotted outside the city limits but within the metropolitan area. Anxious to take advantage of the possibilities of commuting, real estate developers added 800,000 potential building sites to the Chicago region in just thirty years – lots that could have housed five to six million people.
Of course, many were never occupied; there was always a huge surplus of subdivided, but vacant, land around Chicago and other cities. These excesses underscore a feature of residential expansion related to the growth of mass transportation: urban sprawl was essentially unplanned. It was carried out by thousands of small investors who paid little heed to coordinated land use or to future land users. Those who purchased and prepared land for residential purposes, particularly land near or outside city borders where transit lines and middle-class inhabitants were anticipated, did so to create demand as much as to respond to it. Chicago is a prime example of this process. Real estate subdivision there proceeded much faster than population growth.
小題1:With which of the following subjects is the passage mainly concerned?
[A] Types of mass transportation.
[B] Instability of urban life.
[C] How supply and demand determine land use.
[D] The effect of mass transportation on urban expansion.
小題2:Why does the author mention both Boston and Chicago?
[A] To demonstrate positive and negative effects of growth.
[B] To exemplify cities with and without mass transportation.
[C] To show mass transportation changed many cities.
[D] To contrast their rate of growth.
小題3:According to the passage, what was one disadvantage of residential expansion?
[A] It was expensive.
[B] It happened too slowly.
[C] It was unplanned.
[D] It created a demand for public transportation.
小題4:The author mentions Chicago in the second paragraph as an example of a city,
[A] that is large.
[B] that is used as a model for land development.
[C] where the development of land exceeded population growth.
[D] with an excellent mass transportation system.

Even while in a deep sleep, people can still learn brand new information. Sleepers soak in new associations between smells and sounds, knowledge that lingers(逗留)into the next waking day, researchers report online August 26 in Nature Neuroscience.
The new study is the first to show that entirely new information can get into the sleeping mind, says Anat Arzi of the Weizmann Institute of Science in Israel. "The brain is not passive while you sleep. It's quite active. You can do quite a lot of things while you are asleep."
But the results don't mean that Spanish vocabulary tapes now have a place on the nightstand. L, Researchers have tried but largely failed to find evidence that complicated information, such as new pairs of words, can make its way into the brain during sleep.
Instead of trying to teach people something complicated like a new language, Arzi and her colleagues relied on the sense of smell and hearing. As anyone who has walked by a dumpster(垃圾車)in July knows, smells can cause a nose-jerk reaction. Catching a bad smell automatically makes people inhale(吸氣)less, reducing the size of the inhale. But scent of fresh bread causes a long, deep inhale.、rzi and her team took advantage of this reaction for their experiment.
As people slept in the laboratory, the researchers delivered pleasant scent, such as shampoo. As this nice smell got into the sleepers' noses, the researchers played a particular music. Later, a disgusting smell, such as rotten fish or meat, was paired with a different music. Neither the smell nor the sound woke people up. After just four exposures to the smell-music pair during a single night, the sleepers started to automatically respond to the tones without the accompanying smells, taking in bigger breaths when the shampoo-associated tone played and smaller breaths when played the sound linked to the rotten fish smell.
This new learned association lingered into the next waking day, too. Even though the sleepers had no idea they had been exposed to smells or sounds, their behavior proved that their brain had actually learned something during sleep. As before, the shampoo sound stimulated a long, deep inhale, while the rotten fish tone caused more shallow breaths.
小題1:We can infer from the passage that
A.while sleeping, we can learn whatever we want to learn
B.we will increase the size of inhale if we catch a pleasant smell
C.the knowledge we learned while sleeping will be forgotten in the next waken day
D.when walking by a bakery, the fresh bread will cause a nose-jerk reaction
小題2:What is Paragraph 3 mainly about?
A.One can’t acquire complicated knowledge during the sleeping hours.
B.Spanish vocabulary tapes now have a place on the nightstand
C.Researchers have tried to find evidence that the new words can be learned during sleep.
D.Complicated information can make its way into the brain during sleep
小題3:How do Arzi and her team do their research? By
A.giving instructionsB.a(chǎn)nalyzing human brains
C.following the guides of othersD.doing experiments
小題4:In which part of a website may this passage most likely appear?

techniques , but he admitted there would be difficulties in meeting his goal .
“ For example , if you run out of ink while printing on paper , you will throw that paper away . But you cannot throw half-completed buildings away if your material gets stuck , ” he said . Although the printed house is not available to visit , there is a chance for people in Shanghai to see items printed in 3D.
The Belgium-based company Materialise NV held a 3D printing exhibition in Shanghai that started in late 2012 and ended in the middle of 2013 . The company is eager to show Asia what is possible with 3D printing .
“ All the pieces shown here are what cannot be made through traditional techniques . A good example of this customization is hearing aids . More than 10 million people already use 3D printed hearing aids, all made according to the size of their ears , ” said Wim Michiels , executive vice-president at Materialise NV .
“ You can produce anything whenever and wherever you like . You don’t need to set up production lines for pieces that only need a limited amount of products . Setting up a production line is a lot of work . It takes a long time and is very expensive for a limited number of pieces , ” said Michiels .
Kim Francois , managing director of Materialise China , said their European and American clients have already taken the next step toward additive manufacturing with small series production such as hearing aids .
