A、serious contest
A、 Like the combatants in a beat-me-up video game, the makers of videogames consoles do battle in orderly rounds, one of which occurs every five or six years. The current round began in 2000, when Sony launched PlayStation 2. In 2001 Nintendo, the firm that once ruled the industry, launched the GameCube, and Microsoft made its first foray into the cut-throat market with the Xbox. Four years on, Sony is the clear winner, with sales of 70 million consoles, followed by Microsoft with 14 million and Nintendo with 13 million.Next week, the industry’’s biggest trade show,E3, which takes place in LosAngeles, will provide the first glimpses of the next roun
D、It is expected to be a brutal two-way fight. For, after a difficult start, Microsoft has now established itself as Sony’’s main rival, and is gaining momentum. Most important, it has won the crucial support of games publishers, says Nick Gibson of Games Investor, a consultancy. That means Microsoft will "pretty much be neck and neck with Sony" in the next roun
D、Nintendo, by contrast, has been less successful at keeping publishers on board, and has survived thanks only to the strength of its in-house software business.B、 Xbox Live, Microsoft’’s subscription-based online-gaming service, has also been well receive
D、It provides features, such as global player rankings, that Sony cannot match.And although online gaming is still a minority sport, it is expected to be far more significant in the next round, as broadband connections and wireless home networks become more widesprea
D、By signing up customers for Xbox Live now, Microsoft hopes to retain their loyalty into the next roun
D、But perhaps cleverest of all is Microsoft’’s new software-development platform for games, called XNA, a set of software tools that can be used to write games for PCs, Xbox and the forthcoming Xbox 2.According to RobbieBach, Microsoft’’s "chief Xbox officer", insulating programmers from the underlying complexity of the console hardware "creates huge cost efficiency and flexibility. " While Microsoft will probably not unveil the Xbox 2 atE3, says P.J. McNealy, an analyst atAmerican Technology Research, the XN
A、tools will enable the firm to demonstrate the kind of things that will be possible on Xbox 2 when it appears.C、 The contrast with Sony is striking. While Microsoft is focusing on software, Sony is emphasizing hardware innovation for its PlayStation 3. Its plan, which it has yet to describe fully, is to use a new kind of chip, calledCell, as the basis for both the PlayStation 3 and its consumer-electronics devices, such asDV
D、players. With multipleCell chips working in parallel, the PlayStation 3 will be a powerful machine.But its radical new architecture will require games programmers to start from scratch. In the meantime, Sony is trying to keep developers focused on the PlayStation 2.
D、 Microsoft senses an opportunity. It is widely expected to steal a march on Sony by launching the Xbox 2 towards the end of next year, kicking off the next round before Sony is ready. "Microsoft has taken the gloves off," says Mr. McNealy. The PlayStation 3 is not expected until early 2006, and even then only in Japan; analysts do not expect the worldwide launch until late 2006. (Nintendo’’s successor to the GameCube is also expected in 2006.) Last time around, Sony’’s 18-month head start and Microsoft’’s status as the industry’’s newcomer meant that the Xbox never had a chance of catching up with PlayStation 2; it was always going to be just a trial run for Microsoft.But now Sony and Microsoft look evenly matched — and the battle can begin in earnest.Questions 17-20 Below is a list of headings, choose the most suitable choices for partsA~D、and write the appropriate numbers (i-v) on your answer sheet.NB、There are more headings than you need so you will not use all of them and you may use any heading more than once.List of Headingi.

【分析解答题】Computing is driving the philosophical understanding of quantum theoryFor evidence of the power of simplicity, you need look no further than a computer.Everything it does is based on the manipulation of binary digits, or bits-units of information that can be either 0 or 1. Using logical operations to combine those 0s and Is allows computers to add, multiply and divide, and from there go on to achieve all the feats of the digital age.But at each step of the complex operations involved, each bit has a definite value.The same cannot be said of many properties in quantum physics, such as the spin of an atomic nucleus or the position of an electron orbiting such a nucleus.At a small scale, such properties can have more than one value at once. In 1994, Peter Shor, a mathematician then atAT&T’’sBell Laboratories in New Jersey, realised that a computer that used such quantum properties to represent information could factorise large numbers extremely quickly. This is an important problem, because much of modern cryptography is based on the difficulty of factorising large numbers -- so being able to do so quickly would render many modern codes easily breakable. Then, in 1996, a colleague ofDr Shor’’s atBell Labs, Lov Grover, showed that such a quantum computer would be able to search through an unsorted database much faster than an ordinary computer -- another important application.With these insights, quantum computing, which had first been thought of as a possibility in the early 1980s, became a hot topic of research. It was clear to many physicists that using "qubits" -- which, unlike ordinary bits, can exist in a "superposition" of the values 0 and 1 simultaneously -- might yield an exponential improvement in computing power. This is because a pair of qubits could be in four different states at once, three qubits in eight, and so forth. WhatDr Shor andDr Grover showed was that the improvement, if the technological hurdles could be overcome, would be not hypothetical, but real, and useful for important problems.The technology necessary to manipulate qubits, in their various incarnations, is challenging. So far, nobody has managed to get a quantum computer to perform anything other than the most basic operations.But the field has been gathering pace, and is the topic of much discussion among the scientists gathered in Montreal for the annual March meeting of theAmerican Physical Society, the largest physics conference in the worl
D、There are currently several different approaches to quantum computing, all of which rely on fundamentally different technologies, including ultra-cold ions that are cooled by lasers, pulses of laser light, nuclear-magnetic resonance and solid-state devices such as superconducting junctions or quantum dots (which are confined clouds of electrons). What all these technologies have in common is that they can be used to invoke and exploit the bizarre phenomenon of superposition.Superposition is not simple. Though a qubit may, for a while, be in a state of superposition between 0 and 1, it must eventually choose between the two.And in even the best quantum computers, that choice, or "decoherence", happens in a fraction of a millisecon
D、Just how the choice is made, and how to prolong the preceding period of "coherence" that allows quantum computations to be made, constitute a long-unexplained gap at the heart of modern physics. For nearly 80 years, since the inception of quantum theory in the 1920s, most physicists were content to gloss over the process. What is perhaps surprising is that the technological challenge of quantum computing is now a driving force behind efforts to understand the most abstract and philosophical underpinnings of quantum mechanics.
