can be deﬁned for x>0as (x)= ∞e−t t x−1d t.The digamma or psi function is deﬁned as the logarithmic derivative of and (i)for i∈N are called polygamma functions.The ratio (s)/ (r)has been researched by many mathematicians in the past more thanﬁfty years.Wendel[30] gave for0<b<1and x>0the following double inequality:x x+b 1−b(x+b)x b (x)1.(1)Gautschi showed in[8]for0<s<1and n∈N thatn1−s<

and Applied Mathematics 206(2007)1007–1014A strengthened upper bound was given by Erber in [7]:(n +1) (n +s)<4(n +s)(n +1)1−s 4n +(s +1)2,0<s <1,n ∈N .(3)Keˇc ki´c and Vasi´c gave in [12]the inequalities below:b b −1a a −1·e a −b < (b) (a)<b b −1/2a a −1/2·e a −b ,0<a <b .(4)The following closer bounds were proved for 0<s <1and x 1by Kershaw in [13]:x +s 21−s < (x +1) (x +s)< x −12+ s +14 1/2 1−s ,(5)exp [(1−s) (x +s 1/2)]< (x +1) (x +s)<exp (1−s) x +s +12 .(6)Let s and t be nonnegative numbers, =min {s,t },and z s,t (x)=⎧⎪⎨⎪⎩ (x +t) (x +s) 1/(t −s)−x,s =t,e (x +s)−x,s =t (7)in x ∈(− ,∞).In [5,6,27],a monotonicity and convexity of z s,t (x)was obtained:The function z s,t (x)is either convex and decreasing for |t −s |<1or concave and increasing for |t −s |>1.From this,the best bounds in the ﬁrst Kershaw’s double inequality (5)were deduced.For a and b being two constants,as x →∞,the following asymptotic formula is given in [1,pp.257,259]:x b −a (x +a) (x +b)=1+(a −b)(a +b −1)2x +O 1x 2 .(8)For recent development and more detailed information on this topic,please refer to,for example,[5,6,16,27]and the references therein.Recall [18,31]that a function f is said to be completely monotonic on an interval I if f has derivatives of all orders on I and (−1)n f (n)(x) 0for x ∈I and n 0.Recall [23–25]also that a function f is called logarithmically completely monotonic on an interval I if f has derivatives of all orders on I and its logarithm ln f satisﬁes 0 (−1)k [ln f (x)](k)for all k ∈N on I .For our own convenience,the sets of the completely monotonic functions and the logarithmically completely monotonic functions on I are denoted,respectively,by C [I ]and L [I ].In [3,18,23–26],it has been proved that L [I ]⊂C [I ].The well-known Bernstein’s Theorem [31,p.161]states that f ∈C [(0,∞)]if and only if there exists a bounded and nondecreasing function (t)such that the integral f (x)= ∞0e −xt d (t)converges for 0<x <∞.In [3,Theorem 1.1,9]it is pointed out that the logarithmically completely monotonic functions on (0,∞)can be characterized as the inﬁnitely divisible completely monotonic functions studied by Horn in [11,Theorem 4.4].For more information on the classes C [I ]and L [I ],please refer to [2,3,9,18,20,23–27,29]and the references therein.For x >0and a >0,leth a (x)=(x +a)1−a (x +a)x (x)and f a (x)= (x +a)x a (x),(9)where is the classical Euler’s gamma function.In [21,22],among other things,the logarithmically completely monotonic properties of the functions h a (x)and f a (x)are obtained:(1)lim x →0+h a (x)= (a +1)/a a and lim x →∞h a (x)=1for any a >0;(2)h a (x)∈L [(0,∞)]if 0<a <1;(3)[h a (x)]−1∈L [(0,∞)]if a >1;(4)lim x →∞f a (x)=1for any a ∈(0,∞);F.Qi/Journal of Computational and Applied Mathematics206(2007)1007–10141009(5)f a(x)∈L[(0,∞)]and lim x→0+f a(x)=∞if a>1;(6)[f a(x)]−1∈L[(0,∞)]and lim x→0+f a(x)=0if0<a<1.Observe that the functions h a(x)and f a(x)can be rewritten ash a(x)=(x+a)1−a (x+a)and f a(x)=x1−a(x+a).(10)In[4],the function( (x+1)/ (x+s))(x+s/2)s−1for s∈(0,1)is proved to be completely monotonic in(0,∞). These hint us to consider the logarithmically complete monotonicity of the functionH a,b,c(x)=(x+c)b−a (x+a)(x+b)(11)for x∈(− ,∞),where a,b and c are real numbers and =min{a,b,c}. Theﬁrst main result of this paper is the following Theorem1. Theorem1.Let a,b and c be real numbers and =min{a,b,c}.Then (1)H a,b,c(x)∈L[(− ,∞)]if(a,b,c)∈D1(a,b,c),whereD1(a,b,c)={(a,b,c):a+b 1,c b<c+12}∪{(a,b,c):a>b c+12}∪{(a,b,c):2a+1 a+b 1,a<c}∪{(a,b,c):b−1 a<b c}\{(a,b,c):a=c+1,b=c}.(12) (2)[H a,b,c(x)]−1∈L[(− ,∞)]if(a,b,c)∈D2(a,b,c),whereD2(a,b,c)={(a,b,c):a+b 1,c a<c+12}∪{(a,b,c):b>a c+12}∪{(a,b,c):b<a c}∪{(a,b,c):b+1 a,c a c+1}∪{(a,b,c):b+c+1 a+b 1}\{(a,b,c):a=c+1,b=c}\{(a,b,c):b=c+1,a=c}.(13) As a direct consequence of the monotonicity of H a,b,c(x)and a generalization and a reﬁnement of theﬁrst Kershaw’s double inequality(5),the following Theorem2,the second main result of this paper,is established.Theorem2.Let a,b and c be real numbers, =min{a,b,c}and be a constant greater than− .If(a,b,c)∈D1(a,b,c),then inequality(x+c)a−b< (x+a)(x+b)(14)holds in x∈(− ,∞)and inequality(x+a) (x+b)( +a)( +b)x+c+ca−b(15)sounds in x∈[ ,∞).If(a,b,c)∈D2(a,b,c),then inequalities(14)and(15)are reversed in(− ,∞)and[ ,∞), respectively.Remark1.Let us take a=1and0<b<1in inequality(14).Then inequality(x+c)1−b< (x+1)(16)1010F .Qi /Journal of Computational and Applied Mathematics 206(2007)1007–1014is valid in (− ,∞)for (b,c)∈D 1(1,b,c)∩{(b,c):0<b <1}={0<b <1,c b <1}\{(0,0)}.This implies that,in particular,inequality(x +b)1−b < (x +1)(17)is valid in (−b,∞)for 0<b <1.It is clear that inequality (17)not only reﬁnes the lower bound but also extends the range of the argument x of the left-hand side in inequality (5).Remark 2.Now let us take a =1,0<b <1and =1in inequality (15).Then inequality(x +1) (x +b) 1 (1+b) x +c 1+c 1−b(18)validates in [1,∞)for (b,c)∈D 1(1,b,c)∩{(b,c):0<b <1}∩{(b,c):− <1}={0<b <1,c b <1}∩{(b,c):− <1}\{(0,0)}={(b,c):0<b <1,−1<c b <1}.In particular,for 0<b <1,inequality(x +1) (x +b) 1 (1+b) x +b 1+b1−b (19)makes sense in x ∈[1,∞).Standard argument reveals that if x (1/2−√b +1/4)(1+b)1−b √ (1+b)+1(1+b)1−b √ (1+b)−1 (b)(20)then inequality (19)would be better than the right-hand side of (5).It is easy to obtain that lim b →0+ (b)=∞and lim b →1− (b)=e +e −√5e 2e =0.6123686···<1,where =0.57721566...is the Euler–Mascheroni’s constant.This means that inequality (19)reﬁnes the right-hand side of (5)if b is closer enough to 1and that the upper bound in (19)is better than the one in (5)if x is larger enough.Remark 3.The inequality (1)can be rewritten as(x +b)1−b (x +1) (x +b) x 1−b .(21)It is easy to see that the range of the argument x in inequality (17)is larger than that in the left-hand side of inequality (21).Taking a =1,0<b <1and =0in inequality (15)yields(x +1) (x +b) 1 (b) x +c c1−b(22)for (b,c)∈D 1(1,b,c)∩{(b,c):0<b <1}∩{(b,c):− <0}={0<b <1,c b <1}∩{(b,c):− <0}\{(0,0)}={(b,c):0<b <1,0<c b <1}.In particular,inequality(x +1) (x +b) 1 (b) x +b b1−b(23)makes true in [0,∞)for 0<b <1.Whenx >1b 1−b √ (b)−1,(24)the upper bound in (23)is better than that in (21).F .Qi /Journal of Computational and Applied Mathematics 206(2007)1007–10141011Remark 4.Since[H a,b,c (x)]1/(a −b)=1 (x +a) 1/(a −b)=z b,a (x)+x (25)orz b,a (x)=[H a,b,c (x)]1/(a −b)(x +c)−x ,(26)the monotonicity and convexity of z b,a (x)and the logarithmically complete monotonicity of H a,b,c (x)are connected.Remark 5.Eq.(25)shows that (1+b)1−b √ (1+b)in (20)and b 1−b √ (b)in (24)can be rewritten as [H 1,b,b (1)]1/(b −1)and [H 1,b,b (0)]1/(b −1),respectively.The graphs of these two functions,pictured by M athematica 5.2,remind us that these two functions are increasing in b ∈(−1,∞)and b ∈(0,∞),respectively.In [16],using some monotonicity results and inequalities of the generalized weighted mean values with two param-eters in [10,15,14,17,28],it was veriﬁed,among other things,that the functions [ (s)/ (r)]1/(s −r)are increasing in both r >0and s >0.In [27],it was showed that 1/(z s,t (x)+1)∈C [(− ,∞)].Now it is natural to pose the following open problem:let 0, 0, be a real constant and k ∈N such that > (2 )2k −1.For x,y ∈(− ,∞),deﬁne, , ,k (x,y)=⎧⎪⎪⎪⎨⎪⎪⎪⎩1 (x +y)2k −1+ ( +x) ( +y) 1/(x −y),x =y,e ( +y)2 y 2k −1+,x =y.(27)What about the monotonicity,complete monotonicity,logarithmically complete monotonicity or Schur-convexity of the function , , ,k (x,y)?2.LemmasIn order to prove our main results,the following lemmas are necessary.Lemma 1(Abramowitz and Stegun [1]).For x >0and >0,1x =1 ( ) ∞0t −1e −xt d t .(28)For k ∈N and x >0,(x)=− +∞0e −t −e −xt 1−e −t d t .(29)Lemma 2(Qi [19,20]).For real numbers and

and3-log-convexity of the function q , (t)in either (−∞,0),or(0,∞),or(−∞,∞)have been investigated thoroughly.3.Proofs of theoremsProof of Theorem1.By formulas(28)and(29),direct computation yieldsln H a,b,c(x)=(b−a)ln(x+c)+ln (x+a)−ln (x+b),[ln H a,b,c(x)] =b−ax+c+ (x+a)− (x+b)=b−ax+c+∞e−bt−e−at1−e−te−xt d t=− ∞e(c−a)t−e(c−b)t1−e−t+(a−b)e−(x+c)t d t=− ∞[q a−c,b−c(t)+(a−b)]e−(x+c)t d tand,for k∈N,(−1)k[ln H a,b,c(x)](k)= ∞[q a−c,b−c(t)+(a−b)]t k−1e−(x+c)t d t,where q , (t)is deﬁned by(30)in Lemma2.F.Qi/Journal of Computational and Applied Mathematics206(2007)1007–10141013Fig.2.The( , )-domain D2( , )in Lemma2.From q , (0)= − and q a−c,b−c(0)=b−a,it is deduced that if q a−c,b−c(t)is increasing(or decreasing, respectively)in(0,∞)then q a−c,b−c(t)+(a−b) 0in t∈(0,∞)and(−1)k[ln H a,b,c(x)](k) 0in x∈(− ,∞)for k∈bining this with Lemma2reveals that H a,b,c(x)∈L[(− ,∞)]if(a−c,b−c)∈D1(a−c,b−c)and[H a,b,c(x)]−1∈L[(− ,∞)]if(a−c,b−c)∈D2(a−c,b−c).The proof of Theorem1is complete.Proof of Theorem2.By formula(8),it follows thatH a,b,c(x)=1+cxb−ax b−a(x+a)(x+b)=1+cxb−a1+(a−b)(a+b−1)2x+O1x2→1as x→∞for all real numbers a,b and c.If(a,b,c)∈D1(a,b,c),the function H a,b,c(x)is decreasing in(− ,∞)and H a,b,c(x)>lim x→∞=1which can be rearranged as inequality(14).Further,if is a constant greater than− ,thenH a,b,c(x) H a,b,c( )=( +c)b−a ( +a) ( +b)in[ ,∞),which can be rewritten as(15)for x∈[ ,∞).If(a,b,c)∈D2(a,b,c)and is also a constant greater than− ,then the function H a,b,c(x)is increasing in (− ,∞),inequalities(14)and(15)are reversed,respectively.The proof of Theorem2is complete.1014F.Qi/Journal of Computational and Applied Mathematics206(2007)1007–1014 AcknowledgementsThe author would like to express heartily his thanks to the anonymous referees for their valuable

p://en .s ai c a i.c o mQuestions 51-57are based on the following passage.When Ruth Redding,an account manager,was sent on a management training course to improve her relationships with her colleagues by learning how to communicate with them more effectively,instead of being asked to address her boss or her peers,she found herself talking to a horse.In fact,during the course,which is organised by Manch -ester University Business School,Redding found herself standing in a pen whispering to an animal and communicating in a non-aggressive way.This form of communication,which is the subject of the best -selling novel The Horse Whisperer ,later filmed with Robert Redford in the starring role,might appear bizarre on a stud farm,let alone a management training course.But horse whispering is among a number of unusual activities now being used to teach staff about every aspect of working life,from self-confidence to communica -tion.In the 1980s and 1990s,it became fashionable to dump executives on a remote mountainside,or windswept Scottish isle,and leave them to survive a weekend in order to develop initiative,build team spirit and promote leadership skills.An alternative to the classic “chalk and talk ”format,with the lecturer and obedient staff seated round a table,it all seemed wild and rather outlandish.Today,by comparison,it looks increasingly tame.A new generation of management training gurus are adopting a different approach.In Italy,stressed executives have been dressing up as gladiators to confront each other as their ancient forebears did,and in Amer -ica,sales-people are herding cattle,while in Britain,one supermarket reportedly put its executives in Native American teepees for a weekend to develop a spirit of co-operation.Naturally,the originators of these new courses claim to have respectable psychological theories to back them up.Tudor Rickards,a professor at Manchester,was intrigued when he heard about the work done by the famous horse whisperer,Monty Roberts.“The idea is that instead of ‘breaking ’the horse,you co-operate with it.Traditionally,you would coax a horse into a box and then reward it by slamming the door shut.Monty leads the horse in and out of the box and offers it a reward,”explains Professor Rickards.“Monty ’s approach is founded on the recognition of a foal ’s instinctive desire to be part of the herd.”He matched this with research from the Industrial Society,which revealed that often the difference between a successful and unsuccessful leader is trust.“As they observe the way horses react to cer -tain behavior,participants think about how they themselves or other colleagues react to different management styles,”explains Professor Rickards.“The discussion often leads to one about experiences of bullying and abusive behavior,a discussion that might not other -wise surface in a leadership course.We ’ve found this helps the participants draw fine dis -7--赛才英语竞赛论坛h tt p://en .s ai c a i.c o mtinctions between being tough,being assertive,being supportive and being soft.”Team building is also the aim of murder mystery days run by a company called Cor -porate Pursuits.Actors mingle with participants and play out a scene until someone is found “murdered ”.Clues,such as photographs,personal items or a cryptic message,are arranged around the room,and small teams,often pitted against each other,will work to solve the mystery under the gaze of trained observers.Although fun and a sense of release is important,managing director Mandie Chester-Bristow admits that this type of corporate Cluedo occasionally meets with skepticism among clients.“On one occasion,people were messing around and not taking it seriously at all,so I had to say to them,‘You ’re behaving like a bunch of school children.’”An -other challenge can be reporting the observers ’findings.“We would never say,‘You ’ve failed,’if they didn ’t identify the murderer correctly.Instead,we would praise them for the progress they made and how they worked together as a team.”“There are lots of gimmicks in training and headline -grabbing courses at the mo -ment,but what they deliver is often variable,”says Nick Isles of the Industrial Society.“People often say afterwards that they enjoyed the event,but it ’s very difficult to measure how much they ’ve actually learned from it.”He argues that ongoing training in the work place,or courses that last months,are a better way of improving aspects of business such as productivity and customer service.Questions:51.In the first paragraph,what does the writer say about the technique Ruth Reddingfound herself practising?A.It is a way of learning how to address your boss properly.B.It is designed to help managers relax.C.It is perfectly acceptable in its original context.D.It is popular despite its eccentricity.52.According to the writer,management training techniques in the late 1900s wereregarded as .A.undesirable B.innovative C.effective

58-64,markY (for Yes)if the statement agrees with the information given in the passage;N (for No)if the statement contradicts the information given in the passage;NG (for Not Given)if the information is not given in the passage.(7points)Questions 58-64are based on the following passage.For the first century or so of the industrial revolution,increased productivity led to decreases in working hours.Employees who had been putting in 12-hour days,six days a week,found their time on the job shrinking to 10hours daily,then,finally,to eight hours,five days a week.Only a generation ago social planners worried about what people would do with all this new-found free time.In the U.S.,at least,it seems they need not have bothered.Although the output per hour of work has more than doubled since 1945,leisure seems reserved largely for the unemployed and underemployed.Those who work full-9--赛才英语竞赛论坛h tt p://en .s ai c a i.c o mtime spend as much time on the job as they did at the end of World War II.In fact,working hours have increased noticeably since 1970-perhaps because real wages have stagnated since that year.Bookstores now abound with manuals describing how to manage time and cope with stress.There are several reasons for lost leisure.Since 1979,companies have responded to improvements in the business climate by having employees work overtime rather than by hiring extra personnel,says economist Juliet B.Schor of Harvard University.Indeed,the current economic recovery has gained a certain amount of notoriety for its “jobless ”na -ture:increased production has been almost entirely decoupled from employment.Some firms are even downsizing as their profits climb.“All things being equal,we ’d be better off spreading around the work,”observes labour economist Ronald G.Ehrenberg of Cornell University.Yet a host of factors pushes employers to hire fewer workers for more hours and,at the same time,compels workers to spend more time on the job.Most of those incentives involve what Ehrenberg calls the structure of compensation:quirks in the way salaries and benefits are organised that make it more profitable to ask 40employees to labour an extra hour each than to hire one more worker to do the same 40-hour job.Professional and managerial employees supply the most obvious lesson along these lines.Once people are on salary,their cost to a firm is the same whether they spend 35hours a week in the office or 70.Diminishing returns may eventually set in as overworked employees lose efficiency or leave for more arable pastures.But in the short run,the em -ployer ’s incentive is clear.Even hourly employees receive benefits -such as pension contributions and medical insurance -that are not tied to the number of hours they work.Therefore,it is more profitable for employers to work their existing employees harder.For all that employees complain about long hours,they,too,have reasons not to trade money for leisure.“People who work reduced hours pay a huge penalty in career terms,”Schor maintains.“It ’s taken as a negative signal about their commitment to the firm.”[Lotte]Bailyn [of Massachusetts Institute of Technology]adds that many corporate managers find it difficult to measure the contribution of their underlings to a firm ’s well-being,so they use the number of hours worked as a proxy for output.“Employees know this,”she says,and they adjust their behavior accordingly.“Although the image of the good worker is the one whose life belongs to the com -pany,”Bailyn says,“it doesn ’t fit the facts.”She cites both quantitative and qualitative studies that show increased productivity for part -time workers:they make better use of the time they have,and they are less likely to succumb to fatigue in stressful pa -nies that employ more workers for less time also gain from the resulting redundancy,she asserts.“The extra people can cover the contingencies that you know are going to happen,10--赛才英语竞赛论坛h tt p://en .s ai c a i.c o msuch as when crises take people away from the workplace.”Positive experiences with re -duced hours have begun to change the more-is-better culture at some companies,Schor reports.Larger firms,in particular,appear to be more willing to experiment with flexible working arrangements ....It may take even more than changes in the financial and cultural structures of employ -ment for workers successfully to trade increased productivity and money for leisure time,Schor contends.She says the U.S.market for goods has become skewed by the assumption of full -time,two -career households.Automobile makers no longer manufacture cheap models,and developers do not build the tiny bungalows that served the first postwar gen -eration of home buyers.Not even the humblest household object is made without a mi -croprocessor.As Schor notes,the situation is a curious inversion of the “appropriate tech -nology ”vision that designers have had for developing countries:U.S.goods are appropri -ate only for high incomes and long hours.Statements:58.During the industrial revolution people worked harder.59.Today,employees are facing a reduction in working hours.60.Social planners have been consulted about U.S.employment figures.61.Real salaries have not risen significantly since the 1970s.62.The economic recovery created more jobs.63.Bailyn ’s research shows that part-time employees work more efficiently.64.Increased leisure time would benefit two-career households.Section C:You are going to read an article from a newspaper.Six paragraphs havebeen removed from the article.Choose from the paragraphs (A-G)the one which fits each gap (65-70).There is one extra paragraph which you do not need to use.Mark your an 原swers on the Answer Sheet .(6points)Questions 65-70are based on the following passage.Cruising may not be everyone ’s idea of entertainment yet it would hardly be the same without its traditional British teatime.There is no better way of breaking down social barriers either.Or so I found when I enjoyed a cup of tea with an anonymous-I had joined.not be a normal cruising experience,but the Seabourn Spirit is no run-of-the-mill vessel.Nor aboard most cruise ships are you served high-quality leaf tea -it is usually tea-bags,even if it is in a silver pot.11--赛才英语竞赛论坛h tt p://en .s ai c a i.c o mit was personal treatment all the way.Witha passenger-crew ratio of almost one-to-one,there was never any chance of the delaysyou might experience on other craft.Nor do you find many lines where the staff are soquick and keen to learn your particular tastes.would the cabin stewardess put a marker in yourpaperback so you would not lose your place?A small detail-but little pleasures add up togive maximum satisfaction.Yet such high standards might daunt some,fearing that it willbe far from relaxing having to live up to them.But I have not often been on such a happy-go-lucky cruise.Be we president or pleb,we were all treated as equals,and I havebeen on much less distinguished ships with more marked social mores.Just to illustrate my point:aboard Seabourn Spirit,there were just three formaldinners,and not all the men wore dinner jackets.Most evenings were casual or informal.Full silver service meals were available in your cabin as part of the24-hour waiter service.Passengers could also choose between the main dining room and the veranda café. The cuisine was worthy of such a ship and,if it was too nouvelle for some,at least it made eating those cream cakes at tea less of a worry.overcoming the temptation to become a seagoing hermit.All the cabins have broad picture windows and living areas with settee,soft chairs, table and desk.And there is plenty of room for the queen-size bed.The marble bathrooms are a good size with a decent tub-shower and double wash-basins.Most convenient is a closet with enough wooden coat hangers for a débutante’s ball and plenty of room for luggage.to the scenic resort of Yalta and the Livadiya Palace,where Churchill,Roosevelt and Stalin held their famous conference in1945that decided much of the fate of post-war Europe.And we paid a rare cruise ship call to Sevastopol.Mooring near a flotilla of heavily armed warships in what is still a big naval base was one of the more thought-provoking experiences.smiles-a chance at last to indulge in that cruise es-sential,shopping,but with a touch of culture.As a mark of the special attention given to the passengers,the line booked the opera house for an exclusive ballet performance.Even if cruising is not your cup of tea,this is almost certainly the ship to change your mind.12--赛才英赛论坛http://en.saicai.comParagraphs:A.The passenger clearly seemed to be enjoying the occasion.During a gale,howev -er,he might have wished he was back in port.Seasickness can afflict anyone.A good pair of sea legs is one of the few comforts not provided on a ship where ev -ery effort is made to satisfy passengers ’whims.B.Yet nothing moved our emotions more than when we were driven to the site of the Valley of Death.Today,it is a sylvan scene.Had it not been for Olga,our guide,the horror of it would have remained hidden.In perfect English,she recit -ed Tennyson ’s Charge of the Light Brigade .I saw the American woman beside me shed a tear.She was not the only one.C.A more potent concern,even before boarding,was not over-eating but over-drinking.One reason for such high fares is that drinks are included without extra charge.But the mainly elderly passengers stayed as sober as judges -as several were,in fact.D.Although under 10,000tons,a midget of the ocean waves,what it lacks in size it makes up for in quality.“Luxury ”is a much abused word,yet this ship deserves the description.“Exclusive ”may be a better word if you reckon on the ability to pay an average of more than ￡550a day for the pleasure of being there.It was not surprising,therefore,that the majority of the 188passengers on our 12-night jaunt from Istanbul to the Black Sea and Aegean came from the richer golden lodes of the social strata.E.My fridge,too,was stocked to the gunnels.As another compulsion to remain in blissful isolation,the television also relays the ship ’s daily lectures on port news and travel subjects.There were half a dozen grander suites with separate rooms and a balcony.If you could tear yourself away from the room or felt like a more aca -demic pastime,the ship also had its own library,but it would take a world cruise at least to read through the edition of Encyclopaedia Britannica that was included.F.Nothing boosts egos more,or makes one feel more at home,than having the steward know without being reminded that your breakfast croissants should be on -ly slightly warm and that you prefer Orange Pekoe to Darjeeling.G.Sipping from his cup English-style (with milk)with obvious pleasure,he told me:“I enjoy it very much although we do grow excellent tea in my country,Indone -sia.It ’s called Gol Para.Did you know that it is a favourite kind of your Queen?”This surprised me but then who am I to dispute a former president of his country?Section D:In this section,there is one passage followed by 5questions or unfinishedstatements.Read the passage carefully,then answer each question or complete each13--赛才英语竞赛论坛h tt p://en .s ai c a i.c o mstatement in a maximum of 10words .Remember to write the answers on the Answer Sheet .(10points)Questions 71-75are based on the following passage.A massive dinosaur hatchery containing thousands of fossilized eggs and dozens of embryos has been discovered in the Patago -nia region of Argentina,a find that should give researchers their first insight into the embryonic development of these fascinating animals.The eggs were laid by sauropods -placid,plant-eating dinosaurs with long necks and tails and a small head -over anarea of at least a square mile along ancient stream beds,an American and Argentine team said at a news conference in Washing -ton,DC.The find represents the first embryonic fossils containing remnants of skin,the first sauropod embryos and the first dinosaur embryos found in the Southern Hemisphere.Perhaps more importantly,the deposit contains embryos with a broad cross-section of gestational ages and should thus provide paleontologists with their first good look at how the creatures developed during their early stages of life.“There are more than 200sites around the world with fossils of dinosaur eggs,but only a half-dozen that contain embryos,”said paleontologist Philip Currie of the Royal Tyrrell Museum in Alberta.“And these are the most spectacular embryos ever found.”The team members literally stumbled across the specimens.On the second day of their expedition last year,they found the site,which was littered with fossils of egg shells.“You couldn ’t take a step without walking on shell fragments,”said Luis M.Chiappe,of the American Museum of Natural History in New York City,co-leader of the expedi -tion.The team named the site Auca Mahuevo for its tremendous abundance of eggs (huevos in Spanish).The eggs were round,about 5to 6inches in diameter.Had they hatched,the baby dinosaurs inside would have started life a mere 15inches long,but grown to a length of 45feet.Many of the eggs contained not only fossils of the bones of the embryonic dinosaurs,but also fossils of skin fragments.“That is remarkable because the skin is such a delicateWhat the embryos from Auca Mahuevo 14--赛才英语竞赛论坛h tt .s ai c a i.c o m。
