从下面提供的答案中选出应填入下列英文语句中______内的正确答案。

In recent years, one of the more popular topics for panel discussions at computer conferences and trade(1)has been the "RISC versus CISC" debate.

RISC processors feature a small number of instructions that each executes in(2)machine cycle. CISC processors use complex instructions that can take several cycles to execute.

The RISC versus CISC debate won't be decided by panel discussion; it will be won in the marketplace. And the deciding factor may have little to do with the(3)ofinstructions and registers and more to do with parallelism.

Since their conception, RISC processors have been evolving toward microparallelism. Incorporating parallel-processing features(4)the processor, RISC processors feature pipelining, whereby many instructions can be decoded while one instruction executes. RISC processors, however, are moving toward pipelines for each unit of the processor.

CISC processors also employ pipelining. They have many integer instructions that execute in one cycle, but the varying execution times of CISC instructions(5)the effectiveness of parallelism.

serious drop in income over the last 6 months．Frank has circulated a report in which he makes it clear that he feels this is a temporary drawback and he expects the park to return to profitability in the first half year．Now，we have three options facing us：one is to close the park completely；the second is to keep it open but on a much reduced scale and therefore cost and the third，which is basically Frank's view，is to continue as before．I think we've all had time to analyze the figures so I'd like to confine this meeting to your assessment and conclusions．Helmut，how do you see it？

Man2：Very dimly，I'm afraid I see no evidence that the park will return to profitability next year，or for that matter at any time in the foreseeable future…

Man3：I don’t believe you have read a single word…

Man1：Frank．you'll have a chance to give us your point of view in a second．Let Helmut finish first…

Man2：Right，as 1 was saying．I'm afraid Megadrome is a lost cause．We've already lost nearly$400，000 in the last 6 months．We can't afford to continue absorbing those sorts of losses．I think we should close it down as soon as possible and liquidise our assets．

Man3：What do you mean by liquidise our assets？…We wouldn't be able to sell…

Man1：Just a moment，Frank，we'll come to you in a moment．So，let me j ust summarise．Helmut is for closing the park as soon as possible and selling off the land and property．Is that right？

Man2：Yes．I know we’re not likely to get a very good price for the land but I think we're better off selling now rather than waiting another 6 months and finding property prices have fallen even further．

Man1：Thank you，Helmut．Pam，what's your view？

Man4：Helmut's right when he says we've lost an awful lot of money but I think we have to look at it in the wider European context．All our European parks are going through hard times and entry numbers are down in all cases…．

Man2：Maybe，but nothing like…

Man1：Helmut，Let's see what Pam has got to say．

Man4：Yeah，1 was saying all the European parks are suffering as a result of the tough economic climate and we've just commissioned an independent survey of the entire theme park business in Europe which indicates that as many as 40%of all parks will have closed by spring next year．

Man2：Exactly，that's my point．

Man1：Helmut，we'd listened to you．Let's listen to Pam now．

Man4：Right，so we can anticipate a much reduced number of theme park operations next year．At the sanle time，most economists are forecasting a recovery throughout Europe from about the middle of next year．Now，at the moment，our customers are staymg at home and saving their money but I feel we can expect them to start spending again by the middle of next year．

There'll be fewer parks to visit and I think Megadrome could be very well placed to pick up an increased share of the market．

Man1：So．you're in favour of keeping it open？

Man4：Oh，yes，I am．But at a reduced level through the winter months．I'd like Frank to propose a plan for limited opening for the period November to March and then start again with a bang beginning of April in time tO catch the Easter holiday business．

Man1：Right，Pam．So you're in favour of option 2-operating on a much reduced scale-for a 5-month period？

Man4：Right．

Man1：Frank．You've been very patient．No doubt you see this differently．

Man3：Not really．I agree with everything Pam has said，but I'm worried about her conclusions．

Man1：You mean the 5-month reduced operation？

Man3：That's right．I'll look at that option，of course．But you've got to understand that the largest running cost of Megadrome is the depreciation on all the equipment．If we just open at weekends，for example．we'ge got to offset a reduced gate income against the same level of depreciation．

Man2：Frank is right．That's why I feel the only option is to closed down and sell of

A．the Park is too old to manage at present．

B．the Park is suffering a loss in profit in the last quarter．

C．the Park's profit has been falling in the past 6 months．

听力原文： Hi, Ms. Roberts. This is William from the Victoria Theater. I wanted to give you an update on your group reservation. I've booked forty tickets for your group to see the musical Running Away next Thursday. As we discussed, you've received a 25 percent discount because of the size of your group. You will find the seat number at the bottom of each ticket. They're very good seats—in the center, close to the stage. Now, as part of our special group promotion, as I explained, all of you will be able to meet the actors after the show to ask questions and get autographs. Just remember that these seats cannot be changed, and the tickets cannot be returned.

Why has the price of the tickets been reduced？

A．They are for an afternoon performance.

B．They are for a large group.

C．They are for seats at the rear of the theater.

D．They are for a performance today.
