2、,B,C or D.Text 1 Deanne Julius,a former member of the Bank of Englands monetary policy committee,argued in a recent speech that there is a risk of a significant deflationary period in the main economies between now and 2005.But many of todays central bankers,brought up to believe that their job is t
3、o fight inflation,seem to be underplaying the risk.Deflation is much more harmful than inflation.Falling prices encourage consumers to postpone spending in the expectation of cheaper goods tomorrow;they also make it impossible to deliver negative real interest rates if these are needed to drag an ec
4、onomy out of recession.Most dangerous of all is a cocktail of deflation and debt.Deflation pushes up the real burden of debt,while the value of assets linked to that debt,such as house prices,may have to fall even more sharply in nominal terms to return to a fair level.This has already caused severe
5、 balance-sheet problems in Japan,and now America and Germany may be at risk:In both countries debts have surged to record levels.Central bankers in America and Europe but not in Japan still have room to cut interest rates.However,the European Central Bank(ECB)held interest rates unchanged at 3.25%on
6、 September 12th.So long as inflation remains above the ECBs target of“less than 2%”,the bank will be in no rush to ease policy.The Fed is also widely expected to keep rates steady at its policy meeting on September 24th.Why wait,when the risks are so lop-sided?Once deflation sets in,monetary policy
7、can do little to revive an economy.If economies perk up and a rate cut turns out to have been unnecessary,it can be reversed:With ample excess capacity,the risk of inflation taking off is low.Many central bankers do not seem to grasp that this economic cycle is different from its predecessors.The re
8、cession was caused not,as before,by inflation taking off,but by the bursting of an asset-price bubble.American economists blame Japans deflation on the incompetence of its policymakers.There is some truth in this,but the awkward fact is that post-bubble economies tend to be deflation-prone.Even with
9、 interest rates at zero,Japan might have escaped deflation two years ago,when the American economy was strong,by devaluing the yen.But the world economy cannot pull off that trick.That is why central banks in America and Europe need to heed the danger now.“Deflation 学英语 找长喜 2 is like quicksand,”says
10、 Dylan Grice,“easy to get stuck in,more difficult to escape.”1.It can be inferred that many of todays central bankers A dont know how to fight deflation.B dont regard fighting deflation as their job.C dont pay enough attention to the danger of deflation.D dont think there exists a risk of deflation.
11、2.According to the text,during deflation falling prices might lead to A consumers frantic purchasing.B consumers suspending their purchasing plan.C an excess of demand over supply.D the delivery of negative real interest rates.3.The balance-sheet problems in Japan is mentioned to illustrate the dang

14、project are in the final stages of readying the twin robots for launch and picking safe and scientifically rewarding landing sites on the Red Planet.During the past two years,Mars scientists have mulled over some 185 landing sites.They have debated the merits of each,and continue to wrestle with a m
15、atrix of maddening worries from high winds,dust and swings of daylight temperatures to dangerous rocks that might cripple chances for successfully landing and operating the robots.Four landing locales have been culled from a huge list of promising sites.Each has its merits as well as drawbacks.“Firs
16、t and foremost,of course,is the fact that if you dont land safely you dont get any science back.This is in fact the first time that site selection has used science to triage landing sites on Mars,”said John Grant,co-chair of the Landing Site Steering Committee.Those landing locations are on the tabl
17、e because they address the science objectives of the rover missions:Determine if water was present on Mars and whether there are conditions favorable to the preservation of evidence for ancient life.Each wheeled rover carries the Athena package of science gear.That array of equipment has undergone r
18、igorous calibration and testing.Matching Athenas performance to the right site to maximize scientific output and achieve testing of scientific hypotheses is crucial.Each rover will have a primary mission lasting at least three months on the Martian surface.学英语 找长喜 3 Manning served similar duty for t
19、he Mars Pathfinder/Sojournerrover mission that touched down on the Red Planet in July 1997.The project was less than three years from start to launch.Manning said,“We had to do so much over again.So many parts of the system we had to go back and re-engineer for this larger mass vehicle.For instance,
20、the huge gaggle of airbags that cocoons each rover during hard landing has been dropped tested some 50 times.Early tests proved worrisome so much so that significant beefing up of the airbags was necessary.Similarly,there were a number of ill-fated tests of the MER parachute system.That too demanded
21、 considerable extra work to iron out a mission trouble spot.”For Jim Garvin,NASA led scientists for Mars exploration,MER is the first real taste of the surface.The twin rovers armed with the Athena science payload will calibrate the whole community on what Mars is truly like.He said,“I like to call
22、rocks Mother Natures artifacts.I think what MER will give us is far less confusion about two very different types of sites.”6.What does“wrestle with a matrix of maddening worries”(Line 7,Paragraph 1)mean?ATo fight for the threat of some tricky problems.B To evaluate the advantages of each landing si
23、te.C To find the solutions of many complex problems.D To deal with how to operate robots successfully.7.What is the most important thing for scientists to do in exploration of the Mars?A To decide if conditions are favorable for ancient life.B To find the most appropriate landing sites.C To achieve
24、testing of scientific hypotheses.D To calibrate and test the equipment.8.The safe and scientifically rewarding landing sites on the Mars are A places where the robots can land and determine if there is water on Mars.B locations where scientists can get something unknown about Mars.C sites that do no
25、 harm to astronomers and can provide scientific information.D locales where the twin robots can land safely and get scientific information.9.Mannings statement implies that A many parts of the system had to be re-engineered.B NASA attaches great importance to the MER project.C scientists are not sur
