英语问题72
From good reading we can derive pleasure,companionship,
experience,and instruction.A good book may absorb our attention so completely
that for the time being we forget our surroundings and even our identity.Reading
good books is one of the greatest pleasures in life.It increases our
contentment when we are cheerful,and lessons our troubles when we are sad.Whatever
may be our main purpose in reading,our contact with good books should never
fail to give us enjoyment and satisfaction.
With a good book in our hands we need never
be lonely.Whenever the characters portrayed are taken from real life or are
purely imaginary,they may become our companions and friends.In the pages of
books we can walk with the wise and the good of all lands and all times.The
people we meet in books may delight us either because they resemble human
friends whom we hold dear or because they present unfamiliar types whom we are
glad to welcome as new acquaintances.Our human friends sometimes may bore
us,but the friends we make in books need never weary us with their company.By
turning the page we can dismiss them without any fear of hurting their
feelings.When human friends desert us,good books are always ready to give us
friendship,sympathy,and encouragement.
One of the most valuable gifts bestowed by books is experience.Few of us can
travel far from home or have a wide range of experiences,but all of us can
lead varied lives through the pages of books.Whether we wish to escape from
the seemingly dull realities of everyday life or whether we long to visit some
far-off place,a book will help us when nothing else can.(81)To travel by books
we need no bank account to pay our way,no airship or ocean liner or streamlined train to transport us;no passport to
enter the land of our heart's desire.
Through books we may get the thrill of
hazardous adventure without danger.We can climb lofty mountains,brave the
perils of an Antarctic winter,or cross the scorching sands of the desert,all
without hardship.In books we may visit the students of Hollywood;
we may mingle with the gay throngs of the Paris
boulevards; we may join the picturesque peasants in an Alpine village or the
kindly natives on a South
Sea island.Indeed,through
books the whole world is ours for the asking.The possibilities of our literary
experiences are almost unlimited.The beauties of nature,the enjoyment of
music,the treasures of art,the triumphs of architecture,the marvels of
engineering,are all open to the worker and enjoyment of those who read.
72.How would you account for the fact that
people like their acquaintances in books even more?
A.They
resemble human types we like.B.They
are unfamiliar types we like.C.They
never desert us.D.They never hurt our
feelings.
