Text 2 The UK government's decision to shutter plans to build the world's first tidal lagoon off Swansea Bay is a hard blow for Wales.The tidal lagoon project,had it gone ahead,was expected to create 2,200 jobs,plus more in the supply chain.These are the kinds of jobs that Wales,so damaged by steel and coal closures,needs.But the business secretary,Greg Clark,has decided the country can't have them because they would be too expensive.Welsh politicians have reacted with understandable fury to Mr Clark's announcement,which comes almost exactly 12 months after the government abandoned plans to electrify the railway from Cardiff to Swansea,and just a day after Member of Parliament（MPs）voted to press ahead with another expensive infrastructure project:a third runway at Heathrow.There are some rational reasons to approve of this week's decision,while regretting its consequences.No one,including the Tidal Lagoon Power company,denied that the electricity produced off the Welsh coast would have cost more than the cheapest renewables,The most recent government auctions saw offshore wind schemes win contracts at record lows of￡57.50 per megawatt hour,meaning they are within a few pounds of being subsidy-free.But cost is not the only consideration.Otherwise,the government would never have gone ahead with the hugely expensive,risky and uncertain Hinkley Point C nuclear power station.Nor would it have cut subsidies for solar power and onshore wind,as it did in 2015.Those decisions-particularly the promise to curb onshore wind,as the Conservatives did in their 2015 manifest0,despite poll after poll showing that a majority of the public prefers wind and solar to nuclear-were ideological.In a City speech this March,Mr Clark praised business for putting"evidence before ideology".It is welcome that the secretary of state says this is his own approach.Too many of his Conservative colleagues remain too strongly attached to fossil fuels,inclu'ding the prospect of a whole new shale gas industry.As the price of renewables continues to fall,they will surely lose the argument.With Mr Clark in charge,the hope is that onshore wind and solar subsidies may soon return-though too late for UK companies that could have developed and profited from the technology had we not given up on it long before the renewables boom.Yet the government is planning more nuclear power stations,including one in Wales.Different rules seem to apply for different technologies.It looks like a Tory government in Westminster snubbed Welsh Labour's pet project.Backers of the tidal project felt shut out by ministers.Wave energy lobbyists perhaps don't have the firepower in Whitehall that others can muster.Mr Clark might have relied on the evidence to make a tough call not to back a new,green technology.But it's hard to shake off the impression that the decision was one rooted in the partisan politics of self-interest.Paragraph 3 mentions offshore wind schemes to_____A.illustrate renewables'big potentialB.highlight tidal power's high costC.show what subsidy-free power meanD.stress wind energy's cost-effectiveness

问答题Passage 3Tidal Power on the Cheap? A The startup, located on the Orkney Islands, way north of Scotland, has raised ￡6.2 million to build a working prototype of a floating tidal turbine that it says will be cheaper to install and maintain than others being tested now. The 8-meter-long prototype, ideally, will go into the water at the European Marine Energy Centre (EMEC) Tidal Test Site that sits just down the road from ScotRenewables in 2010. Commercial versions of the turbine will measure up to 40 meters long and weigh 250 tons, but generate 1.2 megawatts of power. B “That’s quite impressive when you compare it to others,” said CEO Barry Johnston. “We want to be competitive with offshore wind.” Rather than anchor a permanent turbine on the ocean floor, ScotRenewables will build a floating turbine that is slack moored with chains to an anchor on the sea floor. The body of the turbine-a long 40-meter tube of metal with a point at the end-will face directly into the tide. Below, two turbines attached to fins will convert the power of the tides into electricity. Johnston explained “A 1-meter prototype ScotRenewables is experimenting with in the wave tank is built. It looks like a model rocket with two fins with propellers attached to the ends of the fins.” C Tidal is the potentially most predictable, reliable form of renewable energy. With a tide table and computer, ScotRenewables can calculate the power output of a turbine decades in advance. You can’t do that with intermittent, variable sources like wind, solar or wave. Unfortunately, harnessing tidal power is quite difficult. Some of the prototypes that have been tested in the decades are quickly destroyed by rushing tides. Pulling those turbines up from the sea bed and taking them into the shop consumes time and money. Taking the ScotRenewables turbine in for repairs should be easy: maintenance workers would just have to take a boat out, unhook it, and put another in its place while the first is being entangled. D Tidal power is also 50 percent stronger at the surface than at the seabed so these turbines should be capable of generating more power. Other companies have tried to create surface tidal turbines before. The difficulty has been keeping the turbine pointed in the direction of the tide. Some get washed away. Other times, the creators build large superstructures around the turbine, which costs money. ScotRenewables says it will come up with control mechanisms and advanced hydrodynamics (i.e., aerodynamics in water) to keep the turbines pointed in the right direction. E Scotland is betting heavily on wind and wave power. The notoriously harsh waves and currents of the Pentland Firth, a channel which separates the main body of the U.K. with the Orkneys that is often referred to as the Saudi Arabia of Marine Energy by locals. By 2020, Scotland wants to get half of its power from renewable sources, including large hydroelectric dams. Hydroelectric constitutes about 11 percent of the country’s power now and 9 percent comes from wind and other renewables. A large portion of the new renewable sources of power will come from wind, tidal and wave. Marine energy could provide up to 35 terawatt hours of power to the U.K. by 2020 and 84 terawatt hours of power by 2050, according to Edwina Cook, business development officer at EMEC. The U.K. in 2004 consumed 340 terawatt hours of power. The EMEC has created tidal and wave testing centers for companies to build and validate prototypes. (The Pelamis-that sea snake looking wave power device-was tested at EMEC before commercial rollouts in Portugal.) The government has also passed exceptionally large credits for power providers that put tidal and wave power on the grid. (Prototypes participating in the EMEC test beds are actually connected to the grid and selling small amounts of power.) The hope is that the programme will create jobs, exports and green energy. Offshore, the Dublin based open Hydro Power is already testing a large tidal device that looks like a big rotating fan. F Talking about the prototype and commercial power production, however, is easier said than done. ScotRenewables did not like the software simulation tools it found when it first set out. Some software focused on tidal changes; others focused on waves. To build an effective surface tidal turbine, Johnston realized that both tidal and wave power should be taken into account. Thus, it had to build its own tools, which cost several thousands. It also built its own wave tank. It was easier than trying to book time at an EMEC wave tank. The company now hopes to lease time on the tank to other wave companies to generate revenue. And, because ships to deploy tidal and wave devices are in short supply, it is contemplating buying or building its own multi-purpose vessel. Which paragraph contains the following information? Write the correct letter, A-F, in boxes 1-4 on your answer sheet. 1. New plan has been made to involve a new factor besides tidal. 2. Damages have happened to the models in the past years. 3. A detailed structure of a model is demonstrated. 4. The immature model is expected to apply at the beginning of the twenty first century after further development.
