Wikipedia (維基百科) is a non-profit website funded by donations, started on 15th January, 2001. “Wiki” means “quick” in the Hawaiian language. These days, most people go straight to Wikipedia, the online encyclopedia (百科), to look something up. But how reliable is it?

The site attracts 78 million visitors every month, and it is available in more than 270 different languages. It’s one of the most comprehensive (綜合的) resources available, and it’s got much more information than an ordinary encyclopedia. The site is updated on a daily basis by thousands of people around the world. Anyone with an Internet connection can look through and edit the contents or add a new page at any time. And you don’t need any formal training.

Of course, there are some controls. Wikipedia has a team of more than 1,500 administrators who check for false information. And main targets for horrible comments (such as politicians) are forbidden to public editing. But with more than 16 million articles to keep an eye on, it isn’t easy. So, while Wikipedia benefits from being constantly updated with information from all over the world, it’s also open to “vandals”(故意搗亂者).

Some of the damage is easy to notice. Someone drew horns and a moustache on Microsoft chairman Bill Gates’ photo. But other things are harder to spot. The most common form of vandalism involves adding tiny items of false information into the biography of a famous person. Unbelievably, some of this misinformation has appeared in newspapers, with The Daily Mail, The Guardian and The Independent all having fallen victim to the tricks. For example, in an obituary (訃告) for British comedian Sir Norman Wisdom, one newspaper claimed that he co-wrote Dame Vera Lynn’s wartime song “There’ll be Bluebirds over the White Cliffs of Dover”. In fact, he did no such thing.

So if you’re going to use any information from Wikipedia, make sure you double-check it first.

1.What do we know about Wikipedia?

A. It makes profits from its users.

B. It is run by the Hawaiian government.

3. The example of Norman Wisdom’s obituary is used to show _________.

A. Wikipedia sometimes contains false information

Almost everyone accepts the fact that crime can never be wiped out entirely. Thus control of crime becomes the focus of police and government around the world. The question lawmakers must answer is, “Which system of criminal punishment works best for society?” Each country has developed its own ideas for solution to this question, and these solutions then determine how criminals are punished under different systems. However, none of the current system in use has proved 100 percent effective. There are many ideas about punishment of criminals. Some systems look only to (傾向于) get retribution (懲罰) against criminals. These systems work to frighten criminals away from repeating a crime in the future.

These systems also try to deter (威懾) others in society by using the criminal as an example of what can happen to a person if he or she is caught committing crimes. Rehabilitation (悔過) is another philosophy by which many systems of punishment operate. The goal of these systems is to return a former criminal to society after a required period of treatment and training, usually in prisons. The idea is to help change the person's behavior and approach so that he or she becomes a law-abiding citizen.

Capital punishment is another form of punishment which systems use in extreme criminal cases, sometimes involving such crimes as a murder, rape, and violent theft. In these cases, the person is put to death. Today, capital punishment is used in relatively few countries. Many countries have done away with it. In other words, capital punishment remains only in officially law books but is rarely used. However, capital punishment remains in use in some countries including the United States.

1.The police around the world usually concentrate their attention on_______ .

A. how to catch the person who commits crimes

B. how to punish the person who commits crimes

C. how to control crimes

D. how to determine the system of punishment of criminals

2.Different purposes of the systems of criminal punishment are mentioned in the passage except_________ .

A. to frighten criminals and stop them from committing crimes again

B. to warn others in society not to commit crimes

C. to reform criminals and help them return to society

D. to help criminals get some knowledge of law

3.Which of the following is NOT true?

A. Many countries including the USA have got rid of capital punishment.

B. In some countries capital punishment can only be found in law books, but it is hardly used.

C. Capital punishment is only used in extreme criminal cases.

D. Some countries including China still use capital punishment

I had worried myself sick over Simon's mother coming to see me. I was a new teacher, and I gave an honest account of the students' work. In Simon's case，the grades were awfully low. He couldn't read his own handwriting. But he was a bright student. He discussed adult subjects with nearly adult comprehension. His work in no way reflected his abilities.

So when Simon's mother entered the room, my palms (手掌心) were sweating. I was completely unprepared for her kisses on both my cheeks. “I came to thank you,” she said, surprising me beyond speech. Because of me, Simon had become a different person. He talked of how he loved me, he had begun to make friends, and for the first time in his twelve years, he had recently spent an afternoon at a friend's house. She wanted to tell me how grateful she was for the self-respect I had developed in her son. She kissed me again and left.

I sat, stunned, for about half an hour，wondering what had just happened. How did I make such a life changing difference to that boy without even knowing it？What I finally came to remember was one day, several months before，when some students were giving reports in the front of the class, Jeanne spoke quietly，and to encourage her to raise her voice, I had said, “Speak up. Simon's the expert on this. He is the only one you have to convince, and he can't hear you in the back of the room.” That was it. From that day on, Simon had sat up straighter, paid more attention, smiled more，and became happy. And it was all because he happened to be the last kid in the last row. The boy who most needed praise was the one who took the last seat that day.

It taught me the most valuable lesson over the years of my teaching career, and I'm thankful that it came early and positively. A small kindness can indeed make a difference.

1.We can infer that when Simon’s mother entered the room, the writer felt _______.

A. nervous B. satisfied C. happy D. surprised

2.Why did Simon’s mother come to visit the writer?

A. Because she worried about her son’s poor work.

B. Because Simon asked her to do so.

C. Because she wanted to show her gratitude to the writer.

D. Because she wanted to know her son’s performance in the school.

3.The following words can be used to describe Simon before he met the writer EXCEPT _____.

A. unconfident B. lonely C. clever D. outgoing

4.The purpose of the passage is to ________.

A. share a valuable lesson with readers

B. tell teachers how to be kind to students

C. advise the readers to be kind to others

D. tell the story of Simon
