篇一:
Most of us trade money for entertainment. Movies, concerts and shows are enjoyable but 11 you think that you can't have a good time without spending a lot of money, read on. A little resourcefulness and a few minutes of newspaper-scanning should give you some pleasant surprises.

You will probably see people from all over the world; you will 13 see people of every age, size, and shape, and you'll get a free fashion show, too. Window-shopping is also a 14 sport if the stores are closed.
Check the listings in your neighborhood paper. Local colleges or schools often 15 the public to hear an interesting speaker or a good 16 .

Perhaps you can find a free cooking or crafts 17 in a department store.
Plan ahead for some activities. It is always more pleasant not to have people in front of you in a museum or at a zoo. You may save some money, too, since these places often 18 aside one or two free 19 days at slow times during the week. Make sure that you are including the indispensable 20 that people travel miles to see. If you feel like taking an interesting walk, find a free walking tour, or plan one yourself.

篇二:
Questions 61-65 are based on the following passage.
A useful definition of an air pollutantis a compound added directly or indirectly by humans to the atmospherein suchquantities as to affect humans, animals, vegetation, or material adversely (有害地.. Air pollution requires avery flexibledefinition that permits continuous change. When the first air pollution lawswere established inEngland in the fourteenth century, air pollutants werelimited to compounds that could be seen or smelled—a farcry (悬殊的差别. from the extensive list of harmful substances known today. Astechnology has developed andknowledge of the health aspects of variouschemicals has increased, the list of air pollutants has lengthened. Inthefuture, even water vapor (水蒸气. might be consideredan air pollutant under certain conditions.
Many of the more important airpollutants, such as sulfur oxides, carbon monoxide, and nitrogen oxides,arefound in nature. As the Earth developed, the concentrations ( 浓度. of these pollutants were altered byvariouschemical reactions; they became components in biogeochemical (生物地球化学的. cycles. These serve as an airpurification scheme by allowing thecompounds to move from the air to the water or soil. On a global basis,nature'soutput of these compounds dwarfs that resulting from human activities. However,human productionusually occurs in a localized area, such as a city.
In this localized region, human outputmay be dominant and may temporarily overload the natural purificationscheme ofthe cycles. The result is an increased concentration of noxious ( 有害的. chemicals in the air. Theconcentrations atwhich the adverse effects appear will be greater than the concentrations thatthe pollutants wouldhave in the absence of human activities. The actualconcentration need not be large for a substance to be apollutant; in fact thenumerical value tells us little until we know how much of an increase thisrepresents over the concentration that would occur naturally in the area. Forexample, sulfur dioxide has detectable health effects at0.08 parts per million(ppm., which is about 400 times its natural on monoxide, however, has a naturallevel of 0.1 ppm and is not usually apollutant until its level reaches about 15 ppm.
61、It can be inferred from thefirst paragraph that _________
r vapor is an air pollutant in localized areas
definition of air pollution will continue to change
C.a substance becomes an air pollutant only in cities
air pollutants today can be seen or smelled
62、In what way can naturalpollutants play an important role in controlling air pollution?
function as part of a purification process.
are dwarfed by the pollutants produced by human activities.
are less harmful to living beings than are other pollutants.
have existed since the Earth developed.
63、According to the passage,the numerical value Of the concentration level of a substance is only useful if
other substances in the area are known
is a localized area
can be calculated quickly
naturally occurring level is also known
64、Which of the following isbest supported by the passage?
effectively control pollution, local government should regularlyrevise the air pollution laws.
of the most important steps in preserving natural lands is tobetter enforce air pollution laws.
ntists should be consulted in order to establish uniform limitsfor all air pollutants.
n activities have great impact on air pollution.
65、The passage mainlydiscusses _________
economic impact on air pollution
much damage air pollutants can cause
constitutes an air pollutant
quantity of compounds added to the atmosphere
