     Many of world’s big lakes are threatened by pollution or huge drainage schemes. But there is at least one fairly bright spot. The Great Lake 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 the 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 This uses much lake water(29% of the total that is withdrawn) fro irrigation, while also polluting the lakes and river system. 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 in to 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 is 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 lone history of successful co-operation between the two countries and among the local governments suggests 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.

C the huge drainage schemes are to blame for land run-offs
D the economic change has contributed to environmental improvement
3. which of the following shows that water quality has improved?
A fish and birds show residues of heavy metal.

      It is called softwood, but these days it’s producing nothing but hard feelings. Softwood is used to build houses, stuff that in skilled hands changes from a pile of wood in to a recognizable home in mere days. In the US, about 30% of such softwood comes from Canada. But on March 22nd the Department of Commerce announced that it would slap a tariff of around 29% on Canadian softwood. The Americans contend that Canada is subsidizing its timber industry, and dumping wood on to its neighbour for sale at prices that do not cover its production cost.
      The Canadian hotly deny this, and the two sides are volleying expertise at each other. “They’ve hired their experts, and we’ve hired ours,” says John Allan, president of the British Columbia Lumber Trade Council.
      In Canada the provincial governments own forests, and each province is given considerable freedom in pricing its “stumpage”, as standing trees are oddly called. American critics say the Canadians all but give away those uncut trees. John Perez-Garcia, a professor of forestry at the University of Washington in Seattle, estimates that Canadian logging companies pay as much as 60% less for standing trees than they would if the market set the prices.
      Not so, retort the Canadians. Dan Evans, managers of log exports for British Columbia’s government, points out that stumpage fees cover only a small portion of what it cost a Canadian company to send lumber across the border. These companies, he says, have to build their own roads, re-forest logged land, and pay the cost of planning their sales. “We feel we price our timber competitively.” It is worth noting that for years American companies were themselves accused of receiving subsidies; stumpage prices for trees cut down on federal land were long criticized as too low. Then they were quiet on the subject. But now that most American-produced lumber comes from private forests, government subsidies are anathema.
      In Seattle, Robb Dunn, president of a chain of ten lumber stores, says his customers will just have to put up with higher prices. Some reckon the tariff will increase new-home prices by as much as $1500. That may be a bit high; although lumber prices have gone up lately, they are still below the peak reached last summer. And rising interest rates may slow the American housing market, cutting demand.
      The two sides hope to continue talks. One way out might be an agreement under which Canada taxes its lumber companies until it reforms its pricing policies to America’s satisfaction. But Mr. Allan, for one, is not optimistic. The US, he says, has not negotiated in good faith: “Its government just can’t get a grip in its timber industry, which is too powerful.”
1. why do Americans not feel happy about Canadian softwood?
A 30% of Canadian softwood came into America.
B it produces hard feelings between the two countries.
C Canada is dumping it into America.
D it is sold at a subsidized price.
2. we can infer from the text that        
A Canadian central government sets the price for its forest
B the uncut trees were giver to companies for tree
C Canadian companies pay 60% less for softwood export
D the experts were hired to evaluate the behavior of lumber industry
3. what is Canadians’ answer to Americans’ accusation?
A stumpage fees at present are high rather than low.
B no protection is received from Canadian government.
C raising stumpage fees will not solve the problem.
D lumber price includes many expensive components.
4. why are the Americans silent on their own lumber subsidy?
A they no longer exist
B Americans apply a double standard.
C little lumber comes from federal land.
D private forests monopolise the market.
5. what will probably happen because of this trade war?
A demand for wooden house will fall.
B customers will have to pay high prices.
C Canada will place higher tax on lumber industry.
D the US will negotiate the matter with good faith.

     Violent criminals with something to hide have more reason than ever to be paranoid about a tap on the shoulder which could send them to jail. Queensland police are working through a backlog of unsolved murders with some dramatic success. Greater cooperation between the public and various law enforcement agencies is playing a role, but new genetic-testing techniques are the real key to providing the vital evidence to mount a prosecution.
     Evidence left behind at the scene of any murder is guaranteed to outlive the person who left is. A blood, saliva or tissue sample the size of a pin, kept dry and out of sunlight, will last several thousand years. From it, scientific analysis now can tell accurately the sex of the person who left it.
     When matched against a sample from a crime suspect, it can indicate with million-to-one certainty whether the samples come from the same source. Only twins share identical DNA. So precise is the technology if the biological parents of a suspect agree to provide a sample, forensic scientists can work out the rest for themselves without cooperation from the suspect.
     Queensland forensic scientists have been using the DNA testing technology since 1992, and last year they were recognized internationally for their competence in positive individual identification. That is part of the reason 20 of Queensland’s most puzzling unsolved murders dating to 1952 are being actively investigated. There also have been several recent arrests for unsolved murders.
     Forensic evidence was instrumental in chares being laid over the bashing death of waitress Tasha Douty on Bromptong Island in 1983. Douty’s blood-splattered, naked body was found on a nude sunbathing beach at Dinghy Bay on the island. Footprints in the sand indicated that the killer had grappled with the 41-year-old mother who had fled up the beach before being caught and beaten to death.
     According to Leo Freney, the supervising forensic scientist at the John Centre at Brisbane’s Griffith University, DNA testing has become an invaluable tool for police. Its use is in identifying and rejecting suspects. In fact, he says, it eliminates more people than it convicts.
     “It is easily as good as fingerprints for the purpose of identification,” he says. “In the case of violent crime it is better than fingerprints. You can’t innocently explain things like blood and semen at a crime scene where you may be able to innocently explain fingerprints.” In Queensland, a person who has been arrested on suspicion of an offence can be taken before a magistrate and ordered to provide a sample of body fluid by force if necessary.
1. Evidence left behind at the scene of a crime is all of the following EXCEPT         
A blood
B tissue
C fingerprint
D pin
2. the Queensland police has made dramatic progress in investigating unresolved murders because of          .
A greater cooperation between suspects and the police
B possibilities offered by the DNA testing technology
C police competence in positive individual identification
D new evidence left at the scene of these murders
3. before her murder, Tasha Douty was on Brompton Island probably       
A working as a waitress
B spending her holiday
C having a bath in the sun
D swimming on the beach
4. according to Leo Freney, DNA testing is a valuable tool because it         
A uses fingerprints
B is the real key
C provides sample fluid
D is very accurate
5. the power of the new forensic technology is shown in the fact that it can        
A work out a result even without the suspect’s cooperation
B eliminate more suspects than identify them
C make use of evidence several thousand years later
D take s sample of the suspect’s body fluid by force

      Rebel uprising kills seventy! Plane crash leaves no survivors! Rock star dies of overdose!
Evening newscasts and metropolitan newspapers scream the bad news, the sensational, and the action.
Audiences of today focus upon the sensational action, the violence, the loss, the terror, individually, our lives are redirected, our worlds reshaped, and our images changed. While wary of danger of change, we human beings surrender daily to exploitation oh values, opportunities, and sensitivity. The evolution has brought us to the point that we believe little of what is presented to us as good and valuable; instead, we opt for suspicion and disbelief, demanding proof and something for nothing.
There in lies the danger for the writer seeking to break into the market of today. Journalists sell sensationalism—information as action. The journalist who loses sight of the simple truth and opts only for the sensation loses the audience over the long run. Only those seeking a short-term thrill are in following the journalistic thinking.
How, then do we capture the audience of today and hold it, when the competition for attention is so fierce? The answer is writing to convey action, and the way to accomplish this is a simple one—action verbs.
The writer whose product suspends time for the reader or viewer is the successful writer whose work is sought and reread. Why?
Time often will melt away in the face of the reality of life’s little responsibilities for the reader. Instead of puzzling over a more active, and accurate verb, some journalists often limp though passive voice and useless tense to squeeze the life out of an action-filled world and fill their writing with missed opportunities to appeal to the reader who seeks that moment of suspended time.
Recently, a reporter wrote about observing the buildings in a community robbed by rebel uprising as “thousands of bullet holes were in the hotel”. A very general observation. Suppose he had written, “The hotel was pocked with bullet holes.” The visual image conjured up by the latter is far superior to the former. Here is the reader…comfortable in the easy chair before the fire with the dog at his feet. The verb “pocked” speaks to him.
The journalist missed the opportunity to the reality.
1. This passage provides information to support which of the following?

exploit the short attention span and sensationalize
report only the familiar incidents in order to achieve the transfer of understanding
