16．John is clever，but _______ he sometimes makes some careless mistakes．（　�。�
A．in spite ofB．on the other hand
C．so long asD．on the whole

分析 John聰明，但是另一方面他有時會犯一些粗心的錯誤．

解答 答案是B．本題主要考查介詞短語辨析．in spite of 盡管，不管，表示讓步；on the other hand從另一方面來講，往往前后表示不同甚至相反的方面；so long as 只要，表示條件；on the whole從總體上；根據(jù)句意，空格前后講到不同的方面：一方面聰明，另一方面會犯錯誤，所以答案選擇B．

點評 本題考查介詞短語的語義辨析，考生在平時的學習中應注意積累相應的短語和詞匯，并牢記其意思．在做題時，將短語的意思和題干相結(jié)合，從語法、句子結(jié)構(gòu)尤其是句意上去判斷，句意通順，符合邏輯，即正確答案．

6．[1]Do you remember the title of the last book you read？Are names sometimes just beyond your brain's reach？While forgetfulness isn't necessarily a sign that something's wrong，it can be frustrating（令人沮喪的）．But simple methods can help to sharpen your memory．
[2]Challenge your habits．Sometimes a little bit of habit changing goes a long way．For example，use the‘wrong'hand to do an everyday task several times a day．If you usually brush your teeth with your right hand，use your left．The brain‘knows'whew you're using the wrong hand．It's that confusion that stimulates new brain circuits，as the brain struggles to master a new task．
[3]Get involved in niusic．Listening to music can improve your ability to concentrate and help you to remember what you've learnt．Some types of music actually cause brain neurons（神經(jīng)細胞）to fire more quickly．If you're really looking forward to sharpening your memory，take up a musical instrument．Whatever the instrument，learning to p1ay will tune your brain's ability to analyse and focus．
[41Go out of your way to stay mentally active．What really counts is not the amount of book learning you did at school or university，it's how much you actively use your mind．For example，doing crossword puzzles，learning a second language or playing games can exercise your brain．
[5]．Make sure that you get enough of the B vitamins in your diet．They help to repair brain tissue，and turn food into mental energy．Eat fish 2 or 3 times a week．If you drink coffee，you'll not only get a short-term boost in your ability to concentrate but also long-term benefits as well．Besides，the brain is 85%water，so if you don't drink at least 8 large glasses of water a day，you could suffer from memory loss．

66．What is this text mainly about？（no more than 5 words）Ways/How to sharpen your memory．/Methods of sharpening your memory． 
67．What are the two questions at the beginning used for？（no more than 4 words）
To introduce the topic．/For introducing the topic．
68．How can you get involved in music according to Paragraph 3？（no more than 10 wods）Listening to music and/or taking up a musical instrument．
69．List three ways to use our mind actively．（no more than 10 words）
1）Doing crossword puzzles
2）Learning a second language．
3）Playing games．
70．Fill in the blank in Paragraph 5 with proper words．（no more than 5 words）Watch/Pay attention to your diet．或Get your diet improved．或Have a healthy diet．．

7．It is，perhaps，no accident that many of the outstanding figures of the past were amazingly  versatile men．Right up until very recent times，it was possible for an intelligent person to be familiar with almost every branch of knowledge．Thus，men of genius like Leonardo da Cinci or Sir Philip Sidney，engaged in many careers at once as a matter of course．Da Vinci was so busy with his numerous inventions，that he hardly found the time to complete his paintings； Sidney，who died in battle when he was only thirty-two years old，was not only a great soldier，but a brilliant scholar and poet as well．Both these men came very near to fulfilling the Renaissance （文藝復興） ideal of the‘universal man'，the man who was expert at everything．
Today，we rarely，if ever，hear that a musician has just invented a new type of space rocket．Knowledge has become divided and subdivided into countless，narrowly-defined fields．The specialist is respected； the versatile person，far from being admired，is more often regarded with distrust．The modern world is a world of highly-skilled‘experts'who have had to devote the greater part of their lives to a very limited field of study in order to compete with their fellows．
With this high degree of specialization，the frontiers of knowledge are steadily being pushed back more rapidly than ever before．But this has not been achieved without considerable cost．The scientist，who outside his own particular subject is little more than a fool，is a modern phenomenon； as is the man of letters who is hardly aware of the rapid progress that has been made in technology．Similarly，specialization has indirectly affected quite ordinary people in every walk of life．Many activities which were once pursued （追求） for their own sakes，are often given up in despair：they require techniques，the experts tell us，which take a lifetime to master．Why learn to play the piano，when you can listen to the world's greatest pianists in your own drawing-room？
Little by little，we are becoming more and more separate from each other．It is almost impossible to talk to your neighbor about his job，even if he is engaged in roughly the same work as you are．The Royal Society in Britain includes among its members only the most admirable scientists in the country．Yet it is highly confusing to find that even here，as one of its fellows put it，at an academic（學術(shù)的） lecture only 10% of the members can understand 50% of what is being said!

57．The underlined expression"versatile men"refers toC．
A．highly-skilled specialists   B．brilliant scholars
C．talented people              D．a(chǎn)dmirable scientists
58．According to the passage，if da Vinci and Sydney lived in the modern world，D．
A．they would enjoy a better reputation
B．people would look up to them in amazement
C．they might have made greater achievements
D．they might not be truly appreciated by people
59．By quoting"at lecture only 10% of the members can understand 50% of what is being said"，the writer wants to show that the high-degree specializationD．
A．has made scientists unwilling to share their achievements
B．has widened the academic gap between scientists in the same field
C．has indirectly affected people in every walk of life
D．has brought about a significant increase in interpersonal distance
60．The writer of the passage takes aBattitude towards the high-degree specialization．
A．pessimistic  B．negative  C．supportive  D．friendly．
