16.One day when I was 12,my mother gave me an order:I was to walk to the public library,and borrow at least one book for the summer.This was one more weapon for her to defeat my strange problem-inability to read.
In the library,I found my way into the"Children's Room."I sat down on the floor and pulled a few books off the shelf at random.The cover of a book caught my eye.It presented a picture of a beagle.I had recently had a beagle,the first and only animal companion I ever had as a child.He was my secret sharer,but one morning,he was gone,given away to someone who had the space and the money to care for him.I never forgot my beagle.
There on the book's cover was a beagle which looked identical to my dog.I ran my fingers over the picture of the dog on the cover.My eyes ran across the title,Amos,the Beagle with a Plan.Unknowingly,I had read the title.Without opening the book,I borrowed it from the library for the summer.
Under the shade of a bush,I started to read about Amos.I read very,very slowly with difficulty.Though pages were turned slowly,I got the main idea of the story about a dog who,like mine,had been separated from his family and who finally found his way back home.That dog was my dog,and I was the little boy in the book.At the end of the story,my mind continued the final scene of reunion,on and on,until my own lost dog and I were,in my mind,running together.
My mother's call returned me to the real world.I suddenly realized something:I had read a book,and I had loved reading that book.Everyone knew I could not read.But I had read it.Books could be incredibly wonderful and I was going to read them.
I never told my mother about my"miraculous"(奇迹般地) experience that summer,but she saw a slow but remarkable improvement in my classroom performance during the next year.And years later,she was proud that her son had read thousands of books,was awarded a PhD in literature,and authored his own books,articles,poetry and fiction.The power of the words has held.
24.The author's mother told him to borrow a book in order toA.
A.help cure him of his reading problem
B.let him spend a meaningful summer
C.encourage him to do more walking
D.make him learn more about weapons
25.The book caught the author's eye becauseC.
A.it contained pretty pictures of animals
B.he found its title easy to understand
C.it reminded him of his own dog
D.he liked children's stories very much
26.Why could the author manage to read the book through?B
A.He was forced by his mother to read it.
B.He identified with the story in the book.
C.The book told the story of his pet dog.
D.The happy ending of the story attracted him.
27.What can be inferred from the last paragraph?D
A.The author has had happy summers ever since.
B.The author's mother read the same book.
C.The author's mother rewarded him with books.
D.The author has become a successful writer.

12.What is the nature of the scientific attitude,the attitude of the man or woman who studies and applies physics,biology,chemistry,geology,engineering,medicine or any other science?
    We all know that science plays an important role in our societies.However,many people believe that our progress depends on two different aspects of science.The first aspect is the application of the machines,products and systems of knowledge that scientists and technologists develop.The second is the application of the special methods of thought and action that scientists use in their work.
    What are these special methods of thinking and acting?First of all,it seems that a successful scientist is curious-he wants to find out how and why the universe works.He usually pays attention to problems which he notices have no satisfying explanation,and looks for relationships even if the data available seem to be unconnected.Moreover,he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves.
    He is a good observer,accurate,patient and objective and uses the facts he observes to the fullest.For example,trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum(光谱).
    He does not accept statements which are not based on the most complete evidence available.He rejects authority as the only basis for truth.Scientists always check statements and make experiments carefully and objectively.
    Furthermore,he does not readily accept his own idea,since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation.
    Lastly,he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete.Furthermore,he needs imagination if he wants to guess how processes work and how events take place.
    These seem to be some of the ways in which a successful scientist or technologist thinks and acts.

66.Many people believe that science helps society to progress throughB.
A.knowledge only                        B.more than one aspect
C.technology only                       D.the use of machines
67.Which of the following statements about a curious scientist is TRUE?C
A.He doesn't find confidence and pleasure in work.
B.He is interested in problems that are explained.
C.He makes efforts to investigate potential connections.
D.He looks for new ways of acting.
68.According to the passage,a successful scientist would NOTA.
A.easily believe in unchecked statements      
B.easily criticize others'research work
C.always use his imagination in work  
D.always use evidence from observation
69.What is the author's attitude towards the topic?B
A.Critical.B.Objective.C.Unclear.D.Prejudiced.
70.What does the passage mainly discuss?C
A.Application of technology.
B.Progress in modem society.
C.Scientists'ways of thinking and acting.
D.How to become a successful scientist.

16.Today I am known for my voice.Perhaps the greatest honor came when I was asked to read The New Testament (《新约全书》) on tape.
But it (36)B a long time to believe such good things could happen to me.When I was a child,I stuttered (结巴) so badly that I was completely (37)C to speak in public.

When he learned that I not only loved poetry but was writing it,we became closer.There was,however,one(39)A-Professor Crouch could not stand the fact that I refused to read my poems to the class.

By then the other students had settled at their desks.With knees shaking,I walked up to the front.For a moment I stood there,breathless.Then I began,and kept going.I recited my poem all the way through!
Afterwards,Professor Crouch encouraged me to read other writers'poetry before the public. I discovered I did have a (n)(47)Aand found my classmates actually looked forward to hearing me recite.
