Mother Nature Shows Her StrengthTornadoes（龙卷风）and heavy thunderstorms moved across the Great Lakes and into Trumbull County on Saturday evening.The storms were dramatic and dangerous.George Snyder was driving the fire truck down Route 88 when he first noticed that a funnel（漏斗状的） cloud was behind him."I stopped the truck and watched the funnel cloud.It was about 100 feet off the ground and I saw it go up and down for a while.It was moving toward Bradley Road and then suddenly it disappeared,"Snyder said.Snyder only saw one of the funnel clouds that passed through northeastern Ohio on Saturday.In Trumbull County,a tornado turned trees onto their sides.Some trees fell onto houses and cars.Other trees fell onto telephone and electrical wires as thev went down.Amanda Symcheck was having a party when the storm began."I knew something was wrong,"she said."I saw the sky go green and pink.Then it sounded like a train rushing toward the house.I started crying and told everyone to go to the basement for protection."The tornado caused a lot of damage to cars and houses in the area. It will take a long time and much money to repair everything.There was also serious water damage from the thunderstorms.The heavy rains and high wind caused the power to go out in many homes.The storms caused serious flooding in areas near the river. More than four inches of rain fell in parts of Trumbull County.The river was so high that the water ran into streets and houses.Many streets had to be closed to cars and trucks because of the high water. This made it difficult for fire trucks,police cars,and other rescue vehicles to help people who were in trouble.Many people who live near the river had to leave their homes for their own safety.Some people reported five feet of water in their homes.Local and state officials opened emergency shelters for the people who were evacuated（撤走）.The Red Cross served meals to them."This was a really intense storm,"said Snyder,"People were afraid.Mother Nature can be fierce.We were lucky this time.No one was killed."Several people were missing during the storm.A:RightB:WrongC:Not mentioned

单选题Since 1960, the fast-growing town of Hotstone, Arizona, has drawn water from the Gray River, which feeds Lake Mudfish. If the town’s water use continues to grow at its present rate, in about 20 years the water level of Lake Mudfish will inevitably decrease to the point that it can no longer support its biologically fragile population of fish. The prediction above is based on which of the following assumptions?A
As the town’s water requirements grow, it will not be able to meet those requirements by drawing on water sources other than the Gray River.B
Since 1960, the lake’s population of fish has become more biologically fragile.C
The amount of water that the lake loses to evaporation each year will increase over the next two decades.D
There are multiple sources of water besides the Gray River that feed into Lake Mudfish.E
The town of Hotstone will be able to reverse its trend of increasing water use if it implements an aggressive water conservation program.

问答题Passage 3Cleaning up the Thames A The River Thames, which was biologically “dead” as recently as the 1960s, is now the cleanest metropolitan river in the world, according to the Thames Water Company. The company says that thanks to major investment in better sewage treatment in London and the Thames Valley, the river that flows through the United Kingdom capital and the Thames Estuary into the North Sea is cleaner now than it has been for 130 years. The Fisheries Department, who are responsible for monitoring fish levels in the River Thames, has reported that the river has again become the home to 115 species of fish including sea bass, flounder, salmon, smelt, and shad. Recently, a porpoise was spotted cavorting in the river near central London. B But things were not always so rosy. In the 1950s, sewer outflows and industrial effluent had killed the river. It was starved of oxygen and could no longer support aquatic life. Until the early 1970s, if you fell into the Thames you would have had to be rushed to hospital to get your stomach pumped. A clean-up operation began in the 1960s. Several Parliamentary Committees and Royal Commissions were set up, and, over time, legislation has been introduced that put the onus on polluters-effluent-producing premises and businesses-to dispose of waste responsibly. In 1964 the Greater London Council (GLC) began work on greatly enlarged sewage works, which were completed in 1974. C The Thames clean up is not over though. It is still going on, and it involves many disparate arms of government and a wide range of non-government stakeholder groups, all representing a necessary aspect of the task. In London’s case, the urban and non-urban London boroughs that flank the river’s course each has its own reasons for keeping “their” river nice. And if their own reasons do not hold out a sufficiently attractive carrot, the government also wields a compelling stick. The 2,000 Local Government Act requires each local borough to “prepare a community strategy for promoting or improving the economic, social and environmental well-being of their area”. And if your area includes a stretch of river, that means a sustainable river development strategy. D Further legislation aimed at improving and sustaining the river’s viability has been proposed. There is now legislation that protects the River Thames, either specifically or as part of a general environmental clause, in the Local Government Act, the London Acts, and the law that created the post of the mayor of London. And these are only the tip of an iceberg that includes industrial, public health and environmental protection regulations. The result is a wide range of bodies officially charged, in one way or another, with maintaining the Thames as a public amenity. For example, Transport for London—the agency responsible for transport in the capital—plays a role in regulating river use and river users. They now are responsible for controlling the effluents and rubbish coming from craft using the Thames. This is done by officers on official vessels regularly inspect fling craft and doing spot checks. Another example is how Thames Water (TW) has now been charged to reduce the amount of litter that finds its way into the tidal river and its tributaries. TW’s environment and quality manager, Dr. Peter Spillett, said: “This project will build on our investment which has dramatically improved the water quality of the river. London should not be spoiled by litter which belongs in the bin not the river.” Thousands of tons of rubbish end up in the river each year, from badly stored waste, people throwing litter off boats, and rubbish in the street being blown or washed into the river. Once litter hits the water it becomes too heavy to be blown away again and therefore the rivers act as a sink in the system. While the Port of London already collects up to 3,000 tons of solid waste from the tideway every year, Thames Water now plans to introduce a new device to capture more rubbish floating down the river. It consists of a huge cage that sits in the flow of water and gathers the passing rubbish. Moored just offshore in front of the Royal Naval College at Greenwich, south-east London, the device is expected to capture up to 20 tons of floating litter each year. If washed out to sea, this rubbish can kill marine mammals, fish and birds. This machine, known as the Rubbish Muncher, is hoped to be the first of many, as the TW is now looking for sponsors to pay for more cages elsewhere along the Thames. E Monitoring of the cleanliness of the River Thames in the past was the responsibility of a welter of agencies-British Waterways, Port of London Authority, the Environment Agency, the Health and Safety Commission, Thames Water—as well as academic departments and national and local environment groups. If something was not right, someone was bound to call foul and hold somebody to account, whether it was the local authority, an individual polluter or any of the many public and private sector bodies that bore a share of the responsibility for maintaining the River Thames as a public amenity. Although they will all still have their part to play, there is now a central department in the Environment Agency, which has the remit of monitoring the Thames. This centralization of accountability will, it is hoped, lead to more efficient control and enforcement. Do the following statements agree with the claims of the writer in Reading Passage 3? In boxes 1-8 on your answer sheet, write YES if the statement agrees with the claims of the writer NO if the statement contradicts the claims of the writer NOT GIVEN if it is impossible to say what the writer thinks about this 1. The Thames is now cleaner than it was in 1900. 2. Swimming in the Thames now poses no health hazards. 3. It is now mainly the responsibility of those who pollute the Thames to clean their waste up. 4. All local London boroughs are now partly responsible for keeping the Thames clean. 5. Transport for London now employs a type of River Police to enforce control of their regulations. 6. Rubbish Munchers are now situated at various locations on the Thames. 7. Previously no one department had overall responsibility or control for monitoring the cleanliness of the Thames. 8. British Waterways will no longer have any part in keeping the Thames clean.
