Many of the world’s big lakes are threatened by pollution or huge drainage schemes. But there is least one fairly bright spot. The Great Lakes and St. Lawrence river system between Canada and the United States, which together account for a fifth of the world’s non-polar fresh water, are much healthier than they were. Can they stay that way
Though Lake Michigan is wholly the United States, all five lakes are governed by the Boundary Waters Treaty of 1909, implemented by an independent bi-national joint commission. In 1978, both countries agreed to try to clean up the water in the lakes, several of which were heavily polluted. They have done so though in fact the improvement owes as much to economic change as to government action. Steel and other heavy industry have given way to cleaner industries and services, both in Ontario and in American lakeside states. The result: tests on fish and birds show residues of heavy metals have declined (though dangerous levels of mercury are still found), while in past ten years the rivers near Toronto have been successfully stocked with salmon.
There are still worries. One problem is farming. This uses much lake water 929% of the total that is withdrawn) from irrigation, while also polluting the lakes and river systems. The huge quantities of manure spread on farms in Ontario and Quebec also causes pollution, by running off the land into streams, rivers and then lakes.
Some scientists also worry that water levels will fall permanently. Climate change is likely to cut rainfall in the Great Lakes basin, while ever more water will be drawn from the lakes by a rising urban population. General consumption in the basin will increase by 25% in the next 25 years, according to a forecast by a consultant to the commission.
Other threats include some 140 exotic species of flora, fish and shellfish that have found their way into the lakes, some via ships’ ballast.. The zebra mussel from Eastern Europe is the most notorious and probably most damaging to the environment. It consumes a lot of oxygen (though it also helps to clean the water). Lastly, there is the hazardous prospect of decommissioning Ontario’s two dozen ageing nuclear reactors, which line the shores of Lake Ontario and Lake Huron.
Fortunately, the long history of successful co-operation between the two countries and among the local governments suggest these threats can be managed. Both governments have approved the commission’s plan to set up international watershed boards across the continent. These are to take a "holistic" approach to ecosystems. Maybe the Zebra mussel and the farm run- offs have met their match.

In the first two paragraphs, the author suggests（）

A:the bi-national joint commission has done its routine job. B:the Boundary Water Treaty of 1909 has become out-of-date. C:the huge drainage schemes are to blame for land run-offs. D:the economic change has contributed to environmental improvement.

When there is blood in the water, it is only natural that dorsal fins swirl around excitedly. Now that America’s housing market is ailing, predators have their sights on the country’s credit-card market. Analysts at Goldman Sachs reckon that credit-card losses could reach $ 99 billion if contagion spreads from subprime mortgages to other forms of consumer credit. Signs of strain are clearly visible. There are rises in both the charge-off and delinquency rates, which measure the share of balances that are uncollectable or more than 30 days late respectively. HSBC announced last month that it had taken a $1.4 billion charge in its American consumer-finance business, partly because of weakness among card borrowers.
It is too early to panic, though. Charge-offs and delinquencies are still low. According to Moody’s, a rating agency, the third-quarter delinquency rate of 3.89% was almost a full percentage point below the historical average. The deterioration in rates can be partly explained by technical factors. A change in America’s personal-bankruptcy laws in 2005 led to an abrupt fall in bankruptcy filings, which in turn account for a big chunk of credit-card losses ; the number of filings (and thus charge-off rates) would be rising again, whether or not overall conditions for borrowers were getting worse.
The industry also reports solid payment rates, which show how much of their debt consumers pay off each month. And confidence in credit-card asset-backed securities is pretty firm despite paralysis in other corners of structured finance. Dennis Moroney of Tower Group, a research firm, predicts that issuance volumes for 2007 will end up being 25% higher than last year.
Direct channels of infection between the subprime-mortgage crisis and the credit-card market certainly exist: consumers are likelier to load up on credit-card debt now that home- equity loans are drying up. But card issuers look at cash flow rather than asset values, so falling house prices do not necessarily trigger a change in borrowers’ creditworthiness. They may even work to issuers’ advantage. The incentives for consumers to keep paying the mortgage decrease if properties are worth less than the value of the loan; card debt rises higher up the list of repayment priorities as a result.
Card issuers are also able to respond much more swiftly and flexibly to stormier conditions than mortgage lenders are, by changing interest rates or altering credit limits. That should in theory reduce the risk of a rapid repricing of assets. "We are not going to wake up one day and totally revalue the loans," says Gary Perlin, Capital One’ s chief financial officer.
If a sudden subprime-style meltdown in the credit-card market is improbable, the risks of a sustained downturn are much more real. If lower house prices and a contraction in credit push America into recession, the industry will undoubtedly face a grimmer future. Keep watching for those dorsal fins.
According to the third paragraph, why would the number of bankruptcy filings be rising again

A:There is a change in America’s personal-bankruptcy laws. B:The charge-offs and delinquencies are still low. C:The influence of the personal-bankruptcy laws has been digested. D:The overall conditions for borrowers are getting worse.

Passage 5
"Fingers were made before forks" when a person gives up good manners, puts aside knife and fork, and dives into his food, someone is likely to repeat that saying.
The fork was an ancient agricultural tool, but for centuries no one thought of eating with it. Not until the eleventh century, when a young lady from Constantinpole brought her fork to Italy, did the custom reach Europe.
By the fifteenth century the use of the fork was widespread in Italy. The English explanation was that Italians were averse to rating food touched with fingers, "Seeing all men’s fingers are not alike clean." English travelers kept their friends in stitches while describing this ridiculous Italian custom.
Anyone who used a fork to eat with was laughed at in England for the next hundred years. Men who used forks were thought to be sissies, and women who used them were called show - offs and overnice. Not until the late 1600’s did using a fork become a common custom.

In England, people who used forks at that time were considered （）

A:well mannered B:sissies C:show-offs and overnice D:both B and C
