17、to solve all types of eyesight problems while limiting the side effects. Most eye (27) are about as safe and effective as surgery can be. However, for an Industry that promises (28) , many centers have kept their patients in the dark about (29) . Government are of no help either as there are no (30)

A consumer advocate website posts a series of unhappy endi

The message boards are full of people who came out of Lasik with far better vision but still in misery, (33) poor night vision, dry eyes and worse. So its vital to research the subject before taking surgery. If you believe all the ads, after e

One reason for the spread of the Japanese youth culture is that it provides an Asian (36) to popular cultur

28、were pioneered in France and Japan, could high-speed trains be coming to America? Last year Californias legislators gave $7.7 billion to a project called California High Speed Rail (CHSR). If and when it is completed it will connect San Francisco to Los Angeles, with branch lines to Sacramento and S

29、an Diego. This first slice of what the budget suggests will eventually be a bill for $68 billion will be used to construct 210km (130 miles) of track between Fresno and Bakersfield. But just because the money has been allocated does not mean the line will actually get built. It is far from universal

30、ly popular. Besides the estimated price (and even this is probably a shot in the dark, for big infrastructure projects are hardly known for coming in on budget), it may not even be that fast. The short distances between many of its stations mean trains will rarely be able to reach their planned top

31、speed of 350kph.B Fortunately, California is home to many clever people. One of them is Elon Musk, the hyperactive boss of Tesla Motors, an electric-car company, and SpaceX, a rocketry business (he also sits on the board of Solar City, a solar-energy firm). There is nothing Mr Musk likes more than r

32、evolutionising high-tech industries. And he thinks he has come up with a better way to get California moving than a standard high-speed train. Mr Muskwho is as good at PR as he is at engineeringfirst mentioned his idea, called Hyperloop, last year, prompting excited speculation about what he might h

33、ave had in mind.C On August 12th, in a short document published on the websites of Tesla and SpaceX, all was revealed. Essentially, Mr Musk proposes to revive an old science-fiction idea called the vac-train (short for “vacuum train“). The Hyperloop would carry passengers across California at more t

34、han 1,200kphfaster than a jet airlinerallowing them to zoom between San Francisco and Los Angeles in little over half an hour, compared with more than two-and-a-half hours for CHSR. It would be solar-powered, would take less land than a high-speed railway, and would be cheaper to boot. Mr Musks noti

35、onal budget is around $ 6 billion, less than a tenth of what the high-speed train is supposed to cost.D Vac-trains, as first described in the 1910s by Robert Goddard, would send rolling carriages flying through hermetically sealed tubes (密封管道) from which the air has been evacuated. The trains would

36、thus encounter no drag, and be able to reach immense speeds. Goddard reckoned his design which also proposed magnetic levitation (磁悬浮) instead of wheelswas good for about 1,600kph. This and other designs for transporter tubes inspired much futuristic art. But none was ever built because maintaining

37、a vacuum in a long tunnel is difficult. Pumps must work exponentially harder as the pressure falls, to evacuate the few air molecules that remain. And even a small leak would damage a full-fledged vac-train, which relies on no air at all being able to build up in front of it, and thus slow it down.

38、For that reason, the Hyperloop is not actually a true vac-train. Instead, Mr Musk plans to remove sufficient air from the tubes to give them a pressure roughly a sixth of that on the surface of his beloved Mars, or a thousandth of that on Earth at sea level. This would keep the air resistance low en

39、ough to deal with in other ways.E The chief of these would be to suck up the air that did accumulate in the tube using a fan, and then expel most of it from the pods rear end. Some of this air, though, would be diverted out of the sides through special skis, to create a cushion that would stop the p

40、od (分离舱) touching the tunnel walls.F That, at least, is the theory. There are doubters, of course. Some worry that passengers will not like the prospect of hurtling through a steel tube, in a cramped capsule, at almost the speed of sound. And there are inevitable questions about safety, though the p

41、ods would have wheels that could be used if needed, allowing them to limp to their destinations using batteries if the power failed. But, its breathtaking audacity aside, the thing does look feasible as an engineering project.G The tube would be held above ground, reducing the amount of land it cons

42、umed, and would follow existing roads, which should simplify construction and make maintenance easier. The proposed route features only gentle curves. And the air cushion surrounding each pod should ensure that the ride is smooth. Moreover, although unexpected engineering problems would be bound to

43、crop up, Mr Musks experienceand that of his engineerswith space flight and car design would bode well for overcoming them.H With projects like this, though, good engineering is never enough. Politics and economics are more forbidding obstacles. Being new, the Hyperloop is risky. Also, the CHSR has a

44、 lengthy history going back decades. Much political and reputational capital is invested in it. To replace it now with a completely different design would require a flexibility that Californias government is almost certainly incapable of. Nor is there any reason to believe that Hyperloop would be im

45、mune to the overwhelming cost that every other grand infrastructure project seems doomed to suffer. A few, presumably not Californian patriots, have even suggested that somewhere like Texaswhere the bureaucracy is less stiflingmight be a more feasible place to try the idea out.I Lastly, it is not cl

46、ear just how serious Mr. Musk really is. In the past he has said that, given his other commitments, he lacked the time to try to build the Hyperloop himself. The reason for putting it into the public domain was therefore to give someone else the chance to take it up. But it is hard to think of anyon

47、e else who has both his deep pockets and his technical track record.（分数：71.00）(1).The Hyperloop project is not only technically but also politically and financially challenged.（分数：7.10）填空项 1:_(2).According to a newly posted document, it would only take a little more than 30 minutes for Hyperloop to

48、travel from SF to LF, almost two hours faster than CHSR.（分数：7.10）填空项 1:_(3).Despite the large sum of investment from the Californian government, the project of high-speed train from SF to LA still faces a variety of uncertainties.（分数：7.10）填空项 1:_(4).Hyperloop is not exactly the Goddards version of vac-trains, because it is almost impossible to build a long, ai
