“Indeed,” George Washington wrote in his diary in 1785, “some kind of fly, or bug, had begun to eat the leaves before I left home.” But the father of America was not the father of bug. When Washington wrote that, English had been referring to insects as bugs for more than a century, and Americans had already created lightning-bug(螢火蟲). But the English were soon to stop using the bugs in their language, leaving it to the Americans to call a bug a bug in the nineteenth and twentieth centuries.

The American bug could also be a person, referring to someone who was crazy about a particular activity. Although fan became the usual term, sports fans used to be called racing bugs, baseball bugs, and the like.

Or the bug could be a small machine or object, for example, a bug-shaped car. The bug could also be a burglar alarm, from which comes the expression to bug, that is, “to install (安裝) an alarm”. Now it means a small piece of equipment that people use for listening secretly to others’ conversation. Since the 1840s, to bug has long meant “to cheat”, and since the 1940s it has been annoying.

We also know the bug as a flaw in a computer program or other design. That meaning dates back to the time of Thomas Edison. In 1878 he explained bugs as “little problems and difficulties” that required months of study and labor to overcome in developing a successful product. In 1889 it was recorded that Edison “had been up the two previous nights discovering ‘a bug’ in his invented record player.”

1. We learn from Paragraph 1 that ___________.

A. Americans had difficulty in learning to use the word bug

B. George Washington was the first person to call an insect a bug

C. the word bug was still popularly used in English in the nineteenth century

D. both Englishmen and Americans used the word bug in the eighteenth century

2.What does the word “flaw” in the last paragraph probably mean?

A. Explanation. B. Finding. C. Origin. D. Fault.(故障,毛病)

3. The passage is mainly concerned with__________.

A. the misunderstanding of the word bug

B. the development of the word bug

C. the public views of the word bug

D. the special characteristics of the word bug

Being responsible is actually not that difficult. I used to think it is hard to grow up into a responsible member of the society. An incident happening in a rainy Sunday afternoon changed my attitude. I was on my way to the bookstore and was waiting for the green light while a girl was knocked down by passing car, which drove off quickly. A man immediately gave her first aid and I had joined in without hesitation. Soon many help was given to the girl.

I am a music store owner. One day, when I was cleaning the instruments in my store, I saw an old man come in. His short steps dragged on the carpet. “Is 77 too old to learn the banjo (班卓琴)?” he asked.

“You can learn to play it well,” I replied, holding back my doubts. My mind told me I was giving false encouragement. I reached the instructor’s schedule and gave the rates, the available time and the additional information that he would need. To my surprise and delight, the old man, Carl, began banjo lessons three days later with my most patient teacher.

With nothing to do at home but practice, Carl made surprising progress. After breakfast he practiced for his required half hour. While waiting for lunch he picked up his banjo again for just a couple of minutes. Since TV was difficult for him to see and hear, he often played the banjo in the evenings. Carl was always early for lessons so it was a surprise that he didn’t arrive one Tuesday.

The next morning I listened to the answering machine with sadness. “Carl’s in hospital,” the voice recorded.

Two months later, I shared the newspaper obituary with the banjo teacher. We both shed tears for a surprisingly clever banjo student.

Several months later, a woman came into the store carrying a plant. “This is for Carl’s banjo teacher,” she said. “I’m his wife, Mary.”

“Why did Carl want to play the banjo?” I asked. Mary took a deep breath and let it out slowly. “Carl was at some show when he was 10 years old. He came close to the stage to watch the performers. When they were packing up their instruments, the banjo player said to Carl, ‘You want to see this up close?’ Carl climbed up on the stage and from then on he wanted to play the banjo.” Carl had waited 67 years to realize a dream! Mary gave the plant to Carl’s banjo teacher. “Thank you for the best six months of his life,” she said.

1.How did Carl learn to play the banjo well?

A. By working hard.

B. By taking short cuts.

C. By asking his wife to help him.

D. By finding the best teacher.

2.From Paragraph 2, we can know the author ______.

A. was unwilling to help Carl

B. was giving true encouragement

C. didn’t want to encourage Carl

D. encouraged Carl though he had doubts

3.The underlined word “obituary” in Para.5 means a notice that _______.

A. announces somebody has died

B. announces somebody is needed

C. announces a good piece of news

D. announces a gift for somebody

4.Why did Carl want to learn banjo?

A. He wanted to become a banjo performer.

B. He wanted to make his dream of his young age come true.

C. His wife encouraged him to learn it.

D. He wanted to spend the last best six months of his life.
