    A

    There was once a professor of medicine, who was very strict with his students. Whenever he took

    the chair on the exam committee(考试委员会), the students would be in fear, because he was seldom

    pleased with the answers they gave. A student would be lucky enough if he or she could receive a good

    mark from him. At the end of the term, the students of medicine would take their exam again. Now a

    student entered the exam room and got seated before the committee. This student was a little nervous as

    he knew it would not be so easy to get through the exam at all.

    The professor began to ask. The student was required to describe a certain illness, his description of

    which turned out to be OK. Then the professor asked about the cure for the illness, and the student, too,

    answered just as right. ―Good,‖ said the professor, ―and how much will you give the patient? ‖ ―A full

    spoon,‖ answered the student. ―Now you go out and wait for what you can get,‖ said the professor. At the

    same time the committee discussed carefully the answers the student had given. Suddenly the student

    noticed there was something wrong with his last answer. ―A full spoon is too much, ‖ he thought to

    himself. Anxiously he entered the room and cried, ―Mr. Professor, I’ve made a mistake! A full spoon is

    too much for the patient. He can take only five drops. ‖

    56. The students were afraid of the professor because ___________.

    A. they often angered and disappointed him B. their answers often astonished him

    C. their answers seldom satisfied him

    D. he often misunderstood them and gave them bad marks

    57. Before he left the room, the student probably ___________.

    A. believed that he had passed the exam

    B. thought five drops of medicine would cure the patient

    C. knew he had made a mistakeD. felt he had not done well in the exam

    58. Which of the following is NOT true according to this text?

    A. The patient will be in danger if he’s taken as much as a full spoon.

    B. The doctor will be in trouble if he has given the patient a full spoon.

    C. Since one spoon is more than five drops, the patient will be all right soon after taking one spoon.

    D. If the patient wants to remain safe, he should take no more than five drops at a time.

    59. We can learn from this text that ___________.

    A. someone died in the exam B. the student would probably not pass the exam

    C. the professor was pleased to see the students’ improvement

    D. the slight change may not cause big difference in medical treatment

    B

    Harry and George were employed by Mr. Cook who had a small workshop in the town at the same time. They worked hard and tried to obey the boss. But they were ready to help others. Once an old man was hurt when he was repairing a machine. Mr. Cook refused to send him to hospital but the two young men didn’t listen to him and took him there. The boss had to pay for all the expenses(费用). He was angry with them and made an excuse to send them away.

    Mr. Cook’s brother was the head of the police station in the town and nobody dared to employ the two young men any longer. They had to go to another town where young workers were needed in the mines. And when they got there, there was only a coin left in their pocket. Of course they could buy only two pieces of bread. They thought for a while and George found a way. He went in a shop and put the coin on the counter(柜台) and the boss handed two pieces of bread to him. Then he asked,“Excuse me, sir. Where’s the nearest hospital, please?”

    “Hospital?”the boss asked in reply.

    “Yes, sir,”George said, coughing.“I’ve got bad pulmonary tuberculosis(肺结核)!”

    Hearing this, the man threw the coin out of his shop and called out angrily,“Get out of here!” George picked up the coin and ran away. They came to another shop where all kinds of cakes were sold. George passed the coin to Harry and said, “It’s your turn now, my friend.”

    60. Mr. Cook refused to send the worker to the hospital because____.

    A. it wasn’t his fault B. he was too busy to do that

    C. he wouldn’t pay for the expense D. the man was too old to go on working

    61. Nobody employed Harry and George because ____.

    A. the two young men didn’t work hard

    B. they didn’t dare to displease Mr. Cook’s brother

    C. the two young men were ready to help others

    D. the two young men didn’t listen to their boss

    62. Harry and George went to the town in order to ____.

    A. make fun of the boss of the shopB. buy some bread for nothing

    C. find work in the mines D. find a hospital there

    63. The boss of the shop threw the coin to the ground because he was afraid____.

    A. the young man would return the bread to him B. to be infected(传染) with tuberculosis

    C. the young man would stay there for ever D. to pay some money for the sick man

    C

    A very strict officer was talking to some new soldiers whom he had to train. He had never seen them before, so he began,“My name is Stone, and I’m even harder than Stone, so do what I tell you or there’ll be trouble. Don’t try any tricks with me, and then we’ll get on well together.”

    Then he went to each soldier one after the other and asked him his name.“Speak loudly so that
