Ohio—Lake Erie，the fourth largest lake of North America’s five Great supplies fresh drinking water to an estimated 11 million people in Ohio，Michigan and South Ontario，Canada.
Yet sometimes pollution，both from industrial waste and farm-chemical runoff，leaves large areas of the lake covered in half-meter-thick layers of green slime(黏液)．Scientists blame a lot of chemicals entering the water，which has caused pollution.
To find out where these chemicals come from，the Ohio Department of Natural Resources has been studying data from its network of 14 water-quality monitoring stations installed along the rivers that flow into the Lake Erie basin.
At one point，water from the small stream is diverted into pipe where it is pumped into the testing station.
“We’ll have a sample a day，year round so that really pins down what the chemistry is like，”says Dave Baker of Ohio’s Heidelberg University，who took charge of the monitoring stations for the Department of Natural Resources.
The U．S.Environmental Protection Agency，the federal government’s pollution watchdog，requires point sources，such as factories，to monitor and report their discharges(排出物)．So Baker is looking for where the other sources of pollution come from.
“If there are problems in Lake Erie，we want to know where it’s coming from and make sure we’re putting resources to solve the problem properly，”Baker says.“It’s stations like this that help do that.”
In this case，a primary source of the pollution turns out to be chemical fertilizers that wash off farmland during rainstorms.
Because farmers and ranchers believe fertilizers are essential to high crop yields，they would like to use them.However，the USDA’s Natural Resource Conservation Service isn’t asking them to abandon farm chemicals，but rather to use them more sparingly(慎用地) so that they don’t run off the land when it rains.
Another technique for reducing farm chemical pollution of Lake Erie is cover-crop farming.After the harvest，farmers plant a second quick-growing crop to reduce erosion.The
deep-rooted plants，such as rye or turnips，help to cover the soil，allowing worms and fungi to work their magic and helping the soil to absorb more water and nutrients.
1．Who provides data from Lake Erie?
A．The water-quality monitoring stations.
B．Natural Resource Conservation Service.
C．The Ohio Department of Natural Resources.
D．The U．S.Environmental Protection Agency.
2．The underlined phrase “pin down”in Paragraph 5 means “”．
A．looks through B．explains exactly
C．keep a record of D．show clearly
3．What causes the pollution in Lake Erie?
A．Animal waste from nearby farms.
B．Waste water from a nearby factory.
C．Chemical fertilizers from the fields.
D．Pesticide farmers used to kill locusts.
4．What is the purpose of planting quick-growing crops?
A．To prevent worms from eating crops.
B．To increase the harvest of the farmers.
C．To make full use of chemical fertilizers in the soil.
D．To keep the soil from being washed away.
B
Consumers everywhere are faced with the same dilemma：given limited resources，what sorts of purchases are most likely to produce lasting happiness and satisfaction？Recent research has confirmed that experiential purchases tend to produce greater hedonic(享乐的) gains than material purchases.
The reason why experiences improve with time may be that it is possible to think about experiences in a more abstract manner than possessions.For example，if you think back to a fantastic summer from your youth，you might easily remember an abstract sense of warm sunshine and youthful exuberant(生气勃勃)，but you’re less likely to remember exactly what you did day-by-day.
Material possessions are harder to think about in an abstract sense.The car you bought is still a car and that great new jacket you picked up cheap is still just a jacket.It’s more likely that the experience of that summer has taken on a symbolic meaning that can live longer in your memory than a possession.
Purchasing may have a negative impact on happiness because consumers often buy
“joyless”material possessions，resulting in comfort but not pleasure.In general，people adapt to experiences more slowly than to material purchases.This can be seen in both negative and positive purchases：hedonic adaptation would result in a positive experience causing more happiness but a negative experience causing less happiness than the comparable material purchase with the same initial happiness level.
Experience，however，seems to be more resistant to these sorts of unfavourable comparisons.It is because of the unique nature of experience.It’s more difficult to make an unfavourable comparison when there is nothing directly comparable.After all，each of our youthful summers is different.
It’s well established that social comparisons can have a huge effect on how we view what might seem like positive events.One striking example is the findings that people prefer to earn $50,000 a year while everyone else earns $25,000, instead of earning $100,000 themselves and having other people earn $200,000.
A similar effect is seen for possessions.When there are so many flat-screen HD TVs to choose from，it’s easy to make unfavourable comparisons between our choice and the others available.
5．An abstract sense in the passage refers to awareness of something .
A．you cannot think about
B．you can’ t remember well
C．you cannot understand
D．you cannot see or touch
6．If you make an experiential purchase before a material purchase，you may go to . A．a theatre before going to a store
B．an exhibition before going to a park
C．a mall before going to a grocer’s
D．a market before going to a restaurant
7．The example of earnings is given to actually indicate .
A．how ridiculous people are
B．how people feel content
C．how near-sighted people are
D．how people hold prejudice
8．It is implied in the passage that，after their material purchases，people might . A．enjoy their ownership of what they have bought
B．pick every fault in the products they have got
C．regret making a wrong decision to buy the items
D．leave what they’ve purchased untouched at home
