1、Questions are based on thefollowingpassage.
“THINKING is hard,”(36)__________Daniel Dennet,a professor of philosophy at Tufts University.“Thinking about some problems is so hard that it can make your head ache just thinking about thinking about them.”He has spent hA.f a century pondering some of the knottiest problems around:the nature of meaning,the(37)__________of minds and whether freewill is possible.His latest book,Intuition Pumps(直觉泵)and Other Tools for Thinking,is a precis of those 50 years,distilled into 77(38)__________ and mostly bite-sized chapters.
“Intuiuon pumps”are what Mr Dennet calls thought experiments that aim to get at the rub of concepts.But the aim of this book is not(39)__________to show how the pumps work,but to(40)__________them to help readers think through some of the most profound conundrums.
This pump which Mr Dennet calls a“cascade of homunculi(级联侏儒)”,was(41)__________by the field of artificial Intelligence,An programmer begins by taking a problem a computer is meant to solve and breaking it down into smaller tasks,to be dealt with by particular(42)__________.These,in turn,are(43)__________ of sub.subsystems,and so on.In this way,we are in depth of thinking profound problems.
Of course,Mr Dennet’s book is not a(44)__________solution to such mind-benders;it is philosophy in action.Like all good philosophy,it works by getting the reader to examine deeply held but(45)__________ beliefs about some of our most fundamental concems,like personal autonomy.It is really not all easy read.

3、根据以下资料,回答题:
Wbrld Must Adapt to Unknown Climate Future
A.There is still great uncertainty about the impacts of climate change,according to the latest report from the Intefgovernmental Panel on Climate Change,released today.So if we are to survive and prosper, rather than trying to fend off specific threats like cyclones,we must build flexible and resilient(有弹性的)societies.
B.Today’s report is the second of three instalments(分期连载)of the IPCC’s fifth assessment of climate change.The first instalment,released last year,covered the physical science of climate change.It stated with increased certainty that climate change is happenin9,and that it is the result of humanity’s greenhouse gas emissions.The new report focuses on the impacts of climate change and how to adapt to them.The third instalment,on how to cut greenhouse gas emissions,comes out in April.
C.The latest report backs off from some of the predictions made in the previous IPCC report,in 2007.During the final editing process.the authors also retreated from many of the more confident projections from the final draft,leaked last year.The IPCC now says it often cannot predict which specific impacts of climate change—such as droughts,storms or floods——will hit particular places.
D.Instead,the IPCC focuses on how people call adapt in the face of uncertainty,arguing that we must become resilient against diverse changes in the climate.“The natural human tendency is to want things to be clear and simple.”says the report’s co-chair Chris Field of the Carnegie Institution for Science in Stanford,Califomia.“And one of the messages that doesn’t just come from the IPCC,it comes from history,is that the future doesn’t ever turn out the way you think it will be.”That means,Field adds,that‘'being prepared for a wide range of possible futures is iust always smart”.
E.Here New Scientist breaks down what is new in the report,and what it means for humanity’s efforts to cope with a changing climate.A companion article,“How climate change will affect where you live”,highlights some of the key impacts that different regions are facing.What has changed in the new IPCC report?
F.In essence,the predictions are intentionally vaguer.Much of the firlner language from the 2007 report about exactly what kind of weather to expect,and how changes witl affect people,has been replaced with more cautious statements.The scale and timing of many regional impacts,and even the form of some,now appear uncertain.
G.For example,the 2007 report predicted that the intensity of cyclones over Asia would increase by 10to 20 per cent.The new report makes no such claim.Similarly,the last report estimated that climate change would force up to a quarter of a billion Africans into water shortage by the end of this decade.The new report avoids using such firm numbers.
H.The report has even watered down many of the more confident predictions that appeared in the lcaked drafts.References to“hundreds of millions”of people being affected by rising sea levels have been removed from the summary,as have statements about the impact of warmer temperatures on crops.“I think it's gone back a bit,”says Jean Palutikof of Griffith University in Brisbane,Queensland,Australia,who worked on the 2007 report.“That may be a good thing.In the fourth [climate assessment]we tried to do things that weren’t really possible and the fifth has sort of rebalanced the whole thing.”
So do we know less than we did before?
I.Not really,says Andy Pitman of the University of New South Wales in Sydney,Australia.It is just more rigorous language.“Pointing to the sign of the change,rather than the precise magnitude of the change,is scientifically more defensible,”he says.
J.We also know more about what we don’t know,says David Karoly at the University of Melbourne.“There is now a better understanding of uncertainties in regional climate proj ections at decadal timescales(时标).”
Are we less confident about all the impacts of climate change?
K.Not quite.There are still plenty of confident predictions of impacts in the reponv—at least in the draft chapters that were lcaked last year,and which are expected to be roughly the same when they are released later this week.These include more rain in parts ofAfrica,more heatwaves in southem Europe,and more frequent droughts in Australia(see“How climate change will affect where you live”).It also remains clear that the seas are rising.How do we prepare in cases in which there is low confidence about the effects of climate change?
L.That’s exactly what this report deals with.In many cases,the uncertainty is a matter of magnitude,so the choices are not hard.“It doesn’t really matter if the car hits the wall at 70 or 80 kilometres an hour,”says Karoly.“You should still wear your seat belt.”So when it comes to sea.1evel rise or heatwaves,the uncertainty does not change what we need to do:build sea walls,use efficient cooling and so forth.
M.But in some cases——such as African rainfall,which could go up or down——the models are not giving us great advice.so all we know is that things will change.“We are not certain about the precise nature of regional change,but we are absolutely certain there are going to be profound changes in many regions,”says Pitman.Even then,there are things we can do that will always help.A big one is getting people out of poverty.The report says poverty makes other impacts worse and many suggested adaptations are about alleviating it.The IPCC suggests giving disadvantaged groups more of a voice,helping them move when they need to and strengthening social safety nets.
N.What’s more,all countries should diversify their economies,rather than relying on a few main sources of income that could flood or blow ovel Countries should also find ways to become less vulnerable to the current climate variability.That means improving the way they govem resources like water,the report says.
O.In short,we must become more resilient.That would be wise even if the climate was stable.Our current infrastructure often cannot deal with the current climate,says Karoly,pointing to events like the recent UK floods.“We don’t have a resilient system now,even in extremely well developed countries.”

Focusing on the clue of climate change instead of the severity of climate effects is scientifically more reasonable.

6、 许多人喜欢中餐。在中国,烹饪不仅被视为一种技能,而且也被视为一种艺术。精心准备的中餐既可口又好看。烹饪技艺和配料在中国各地差别很大。但好的烹饪都有一个共同点,总是要考虑到廒色、味道、口感扣营养(nutrition)。由于食物对健康至关重要,好的厨师总是努力在谷物、肉类和蔬菜之间取得平衡,所以中餐既味美又健康。

9、西安碑林博物馆创建于1087年,是一座艺术宝库(treasury of art),其中收藏有早的古代石碑。从数量上,这座博物馆也是居我国同类博物馆之,保存有从汉代到清代地各代石碑共3000多块。这里碑石如林,所以叫碑林。这里的石碑记录了我国文化发展的部分文化成就,反映了中外文化交流的历史,因而驰名中外。来西安旅游,如不参观碑林,将会遗憾终生。


10、大熊猫是世界上珍贵的动物之一,主要栖息在中国的四川、甘肃和陕西的山区。数量十分稀少,被称为中国的“国宝”。大熊猫是一种哺乳动物,毛色黑白相间,体型肥胖。竹子是大熊猫爱吃的食物,约占食物总量的99%。由于大熊猫对生活环境要求苛刻,食物种类单一,且生育率十分低下。现存大熊猫只有1000只左右。中国政府现已采取多项措施来保护这一濒危动物(endangered spec i es)。
