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.
1.According to the first paragraph，which of the following is NOT true?
A．People often fail to notice indoor air pollution.
B．Indoor air pollution sometimes is more dangerous than outdoor air pollution.
C．Outdoor air pollution may not be so serious as indoor air pollution.
D．It is obvious that people have been paying more attention to indoor air pollution.
2.According to the author，which may NOT be the source of indoor air pollution?
A．Building materials. B．Wet carpet.
C．Cooling system. D．Refrigerators.
3. What does the underlined word “irritation” in the third paragraph probably mean?
A．Bad intention. B．Much sensitivity.
C．Injury. D．Carelessness.

It’s often said of British people that they are very aware of each other’s social rank. Britons can usually work out a fellow countryman’s background from the way they speak or dress, and may even treat them differently based on this. But although this may have been truer in the past than it is today, visitors to Britain say that they still notice it. The comic play Pygmalion (1913), by the Irishman George Bernard Shaw (1856-1950), is a famous exploration of the importance of social rank in British society.
The main story of the play concerns a working class girl, Eliza Doolittle, a flower seller from London. Two upper class gentlemen try to see if they can get Doolittle to appear like an upper class lady after sending her for elocution lessons. Professor Henry Higgins, a language expert, says it can be done; his friend Colonel Pickering says that it’s impossible. Even so, Higgins sets out to teach Eliza how to “speak properly”.
Of course, Eliza isn’t a lump of clay; she has her own will. She can see that it’s in her best interest to go along with Higgins’ plan to “improve herself”. She wants to be able to sell flowers in a shop rather than on the street. After the training, Eliza proves that a flower girl can pass herself off as a lady at a ball. She is a triumph (赢家), and Higgins has won his bet.
But what happens next? Eliza has her future to worry about. She may be able to fool the upper class into thinking she’s one of them, but she isn’t really one of them.
Shaw seems to be telling us that social rank is about more than the way someone talks-it’s about wealth and privilege. The whole experiment proves the idea that accents and classes are very superficial (肤浅的). The way one speaks and dresses are only markers of class. The class system itself, however, is something completely different.
1.What can we learn about speaking and dressing from Paragraph 1?
A. They determine Britons’ social rank.
B. Britons are stricter in them nowadays.
C. Britons no longer care about them.
D. They could affect others’ opinion of a person.
2.Which can replace the underlined word “elocution”?
A. dress B. manners
C. speech D. dance
3.What happens to Eliza Doolittle during the experiment?
A. She is forced to give up selling flowers on the street.
B. She is unwilling to participate in the experiment.
C. She is thought of as an upper-class lady at the hall.
D. She is hopeful about her future.
4.Which of the following would Shaw probably agree with?
A. One can enter the upper class after receiving training.
B. People should try their best to improve their accents.
C. The way people speak greatly affects their social status.
D. Social rank can t he judged by dressing or speaking.

Many people once thought that air pollution had a bad influence upon only the area immediately around large cities with factories and heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is nearly worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of factories and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide( 二氧化碳) in the air resulting from the burning of fossil fuels (coal and oil) is creating a“greenhouse effect” － holding in heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.
Another opinion, less widely held, is that increasing tiny substances in the atmosphere are blocking sunlight and lowering the earth’s temperature－a result that would be equally disastrous.A drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen (though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we are very lucky, the two tendencies will make up for each other and the world’s temperature will stay about the same as it is now.
1.As pointed out at the beginning of the passage, people used to think that air pollution _____.
A. caused widespread damage in the countryside
B. affected the entire eastern half of the United States
C. almost brought worldwide effect
D. existed merely in urban and industrial areas
2.As far as the greenhouse effect is concerned, the author _____________.
A. shares the same view with the scientists
B. is uncertain of its consequence
C. rejects it as being ungrounded
D. thinks that it will increasingly destroy the world
3. It can be inferred from the passage that ____________.
A. raising the world’s temperature a little would not do much harm to life on earth
B. lowering the world’s temperature a little would lead to agricultural disasters
C. almost no temperature changes have occurred over the past decade
D. the world’s temperature will remain constant in the years to come
4.This passage is primarily concerned with _____________.
A. the greenhouse effect in the world
B. the measures to adjust the climate
C. the potential effect of air pollution
D. the measures to protect the environment

Most of the time, people are well aware of the circumstances of exchange: they exchange this for that. But in the rare circumstances when they’ve not prepared with gift-giving in return, they can be _________ with feelings of guilt. Receiving a gift, Jacques Derrida, a French thinker, thought, could make one feel like a _________ trapped in a cycle of economic exchange. People don’t like the feeling of being under obligation (人情债) , and try to dismiss the _________ they can feel as quickly as possible.
Private gift-giving, as the Frankfurt school theorist Theodor Adorno worried, has become an empty procedure. There’s no denying that in at least some cases, people give gifts _________. This has less to do with gift-giving itself, and more to do with the choosing of gifts. Gift-giving looks like an obligation, and a fairly _________one at that. Sure, there is giving gifts to lovers, friends and family. But then there is also the world of gift-giving like Secret Santa Claus, practices that keep gift-giving routines going well _________ the circles of people we know well enough to make choosing presents _________.
For these forced occasions, for, say, the coworker we’ve never spoken to, there are pre-printed cards and commercial guides. Even when the receiver is well-known, people want to _________ the effort needed for gifting. A relative once sent me a gift basket of dried fruit, nuts and cured meats; both the offending party and I are vegetarians.
If gift-giving has become more transaction (交易的), with the give-and-take a(n) _________ itself, so has complimenting.
This ____________ choice — fulfill your obligation to return the ____________ or resign yourself to guilt — comes from belonging to a society structured around commodities and their ____________.The trouble is, if compliments are transactions, feeling that we’re under obligation is a natural state of affairs. To imagine that we could completely overcome our ways of thinking about compliments, ____________, requires ____________ our social and economic forms of life. ____________ a difficult demand, this could be the true gift Adorno and Derrida were hoping for.

Most people know that listening to music when they are feeling down or depressed can encourage their spirits.
However studies have also shown that music, especially certain tones can reduce stress. Music can change brainwave patterns, deepen breathing, and bring on a totally stress-free and more open mindset（心态）. Using music to relax when considering a particular problem may not only raise your mood, but also could help you reach that "a-ha"moment and find a solution.

On the contrary, we can share in the delight of songs of joy and happiness, or any song or piece of music that reminds us of a particular happy time in our past.

Most interviewees are probably aware that interviewers are not supposed to ask them certain questions. There are some areas of special in selection interviewing. Our goal here is to point out these areas of questions and to suggest strategic ways to them as an interviewee.
Courts have that it's none of the company's business how many children an applicant has; or whether he or she is married, or divorced. In this area, if you are asked an illegal question, you can give a general ; saying elegantly: "I would prefer to stick to job-related questions:" Or you can be more : "Are children a requirement for this position?"
, many instances of illegal interview questions occur in' the course -of getting-to-know-you small talk during an interview and aren't by the interviewer as an invasion（侵犯）of your privacy. But innocent or not, illegal interview questions can a company in court when a job seeker discrimination in the interview process.
To age discrimination in hiring, courts have disallowed these sorts of questions: "How old are you?" "When did you graduate from high school?" and so on. Managers get in trouble here when they talk about the average age of their workforce in to -the candidate： "Our typical employee is probably 8 to 10 years older than you. Do you expect problems managing people older than yourself?" You can imagine the later court . Manager: "But, Your Honor, I never asked her age!”Candidate: "My age seemed to be one of his key about my ability to manage." And, of course, you can avoid all these disputes（争执）by simply answering your employer: "Age has been a consideration for me in my work life."
In another area of sex, an employer cannot ask questions about the person's gender（性别） the job specifications strictly require either a male or a female. The burden of proof is on the to demonstrate（论证）that only a man or a woman can do the job. Employers should be cautious: Courts and the Equal Employment Opportunity Commission have interpreted very the concept that only one gender can perform a particular job.
