       The mystery had reached its climax（高潮）：The man had undoubtedly been murdered．However, no one present knew who could have killed such a kind person． It was therefore time to call in the great detective, who gave one searching glance at the corpse（尸體）, and then used a microscope．

       “Aha!” he jumped as he picked a hair off the dead man’s coat．“The mystery is a mystery no longer．We have only to find the man who lost this hair, and the criminal will be in our hands．” The chain of logic was complete, and the detective started to do his search．

       For four days and four nights he moved unobserved through the streets of New York, scanning closely every face, looking for a man who had lost a hair．On the fifth day he discovered a man pretending to be a tourist, and his head was enveloped in a cap reaching below his ears．The man was about to board the Gloritania, and the detective lost no time in following him on board．

       “Arrest him!” shouted the detective, and then, drawing himself to his full height, he took out the hair．“This is his,” said the great detective, “and it proves his guilt．”

       “Remove his hat,” ordered the ship’s captain firmly．

       It was discovered that the man had no hair．

       “Aha!” said the great detective without a moment’s hesitation． “He has committed not one murder, but about one million!”

60．Before the great detective arrived, it seemed that ________．

       A．the man had died of natural causes     B．no one could possibly have murdered the man

       C．the mystery would be easy to solve       D．the dead man was covered with hair

61．The detective declared the mystery would be solved soon _________．

       A．a(chǎn)fter he found the murderer        B．before he used the microscope

       C．a(chǎn)fter he found a hair              D．before he looked at the corpse

62．The tone of this story is ________．

       A．scientific           B．serious    C．educational   D．humorous

63．The main idea of this story is that ________．

       A．those using logic are not always logical

Every night for a year, Neil Simons quietly went out of his house. He wanted to “talk” to an owl (貓頭鷹)settling for the night at the end of his garden. He made owl cries like a real wild owl and was happy to hear the bird “hooting (大聲叫囂)” back to him.

Last year Fred Cornes moved in next door. He heard an owl hooting and answered back. For 12 months the neighbors got into the back gardens of their homes, thinking they were talking with nature. Mr. Simmons kept a diary of all his talks with his bird friend. They would both be out again tonight if it wasn’t for a chance talk between their wives.

Mr. Simmons said. “My wife Kim was telling Fred’s wife Wendy about my owl watching and described how I got the birds to boot back. She said, ‘That’s funny — that’s just what Fred has been doing.’ Then the penny dropped, I felt such a fool when I found out. The trouble is that owl calls aren’t exactly the same and it’s easy to make a mistake.”

Mr. Cornes said, “I’m really flattered (過獎(jiǎng)). I didn’t know I sounded so real. I love nature and I couldn’t resist hooting at the owls. I was very excited when they hooted back. I’m sorry that I was fooling my neighbor who was fooling me.” w*w^w.k&s#5@u.c~o*m

When Cathleen Gardiner’s twins were born 17 years ago, doctors told her that they were a pair in a million. One had Down syndrome(低能綜合癥), while the other did not. Here, Cathleen tells their touching story.

    Since Sean was born 17 years ago, I have always thought that he is just as wonderful as his brother and sister. Though he had a disability(殘疾), we have never viewed him as a burden. He has always been a blessing. The doctors explained that though they were twins, they came from two different eggs. Lisa could walk at 11 months old, while Sean didn’t take his first steps till he was three. By two, Lisa was talking a lot, but Sean wasn’t able to speak until he was nearly four.

    For the first five years of his life, Sean needed a great deal of care. Looking after him was my full-time job, though I also worked as a technical adviser in a computing company. We never treated them differently. We gave them the same toys and spoke to them in the same way. We encouraged Sean to keep up with Lisa, even though he never could, and we would help him develop his abilities. We sent them to the same primary school even after doctors advised us that Sean should go to a school for the disabled.

    We had to explain to Lisa that he wouldn’t learn as quickly as she would. She told us that she’d help him with his school work. Having a non-disabled twin has really helped Sean develop. The love they share has given him a great deal of support. Now Sean and Lisa are both about to finish high school. I don’t think he would have done nearly as well today without Lisa’s help.

50. At least how many children does Mrs. Gardiner have?

A. Two.     B. Three.  C. Four.   D. One.

51. Mrs. Gardiner and her husband regarded Sean as _______.

A. a boy making others touched

B. a normal child without disabilities

C. a special gift

D. a burden of their family

52. The third paragraph mainly tells us that _______.

 A. the couple treated the twins equally

B. Cathleen did all she could to look after Sean

C. the couple didn’t follow the doctor’s advice

D. the couple encouraged Sean to grow up

53. This passage tells us that _________.

A. love can do wonders     

B. nobody is foolish or clever

C. being stupid doesn’t matter

D. all men are born equal
