What do you do when you need to look something up? Go to the library? Open an encyclopedia(百科全书)? Click onto the Internet? These days, most people go straight to Wikipedia, the online encyclopedia. But how reliable is it?
There’s no denying the popularity and usefulness of Wikipedia. It attracts as many as 78 million visitors every month, and the site is available in more than 270 different languages. It’s one of the most comprehensive resources available, which includes almost all details, facts and information that may be concerned. 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 log on and edit the contents or add a new page. 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 harmful comments(such as politicians) are off-limits 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”（恣意破坏公共财物者）.
Some of the damage is easy to notice. One person drew devil horns and a moustache on Microsoft chairman Bill Gate’s photo, while another edited Greek philosopher Plato’s biography to say he was a “Hawaiian weather man who is widely believed to have been a student of ‘Barney the purple Dinosaur’.
But other things are harder to spot. The most common form of vandalism (恣意破坏公共财物罪)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 dirty tricks. For example, in an article about British comedian Sir Norman Wisdom, one newspaper claimed that he co-wrote Dame Vera Lynn’s wartime hit There’ll be bluebirds over the White Cliffs of Dover. He did no such thing. And in other article, it was reported that TV Theme tune composer Ronnie Hazlehurst had written the S Club 7’s hit Reach again, not true.
So, if you’re going to use any information from Wikipedia, make sure you double-check it first.
1.We can learn from the passage that ______.
A. because of its popularity, 78 million people from 270 countries visit Wikipedia monthly.

D. the primary job of the administrators is to make sure true information is conveyed.
2. What’s the writer’s attitude to Wikipedia?

3.Paragraph 5 mainly tells us ______.
A. it is really difficult to find out tiny items of false information.
B. no matter how famous the papers are, they can also be cheated.

4.What’s the best title for the text?

The ocean bottom, a region nearly 2.5 times greater than the total land area of the earth, is even today largely unexplored. Until about a century ago, the deep ocean floor was completely inaccessible and hidden beneath waters averaging over 3,600 meters deep. Totally without light and in the case of intense pressures hundreds of times greater than at the earth’s surface, the deep-ocean bottom is a strange environment to humans, in some way as frightening and remote as the outer space.
Although researchers have taken samples of deep-ocean rocks for over a century, the first detailed global study of the ocean bottom did not actually start until 1969, with the beginning of the National Science Foundation’s Deep Sea Drilling Project(DSDP). Using techniques first developed for the offshore oil and gas industry, the DSDP’s drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean’s surface and drill very deep waters, taking samples of rocks from the ocean floor.
The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983. During this time, it sailed 600,000 kilometers and took almost 20,000 samples of rocks around the world. Those samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to make out what it will probably look like millions of years in the future. Today, largely on the strength of evidence gathered during the Glomar Challenger’s voyages, nearly all earth scientists agree on the theories of plate tectonics (构造学) and continental drift that explain many of the geological processes.
The sample of rocks drilled by the Glomar Challenger have also provided a climatic record stretching back hundreds of millions of years. The information of past climatic change can be used to predict the future climate.
1.What does the underlined word “inaccessible” in paragraph1 mean?
A. unrecognizable B. unreachable
C. unusable D. unreasonable
2.Which of the following is TRUE about the Glomar Challenger?
A. It is a military submarine.
B. It is used to develop tourism.
C. It has gone on over 100 voyages.
D. It made its first DSDP voyage in 1969.
3.The Deep Sea Drilling Project was significant because it was _____.
A. the first detailed exploration of the ocean bottom
B. conducted by geologists from all over the world
C. supported entirely by the gas and oil industry
D. an attempt to find new sources of oil and gas

The State Council submitted (提交) a bill which aims to allow couples to have two children if either parent is an only child. It focuses on adjusting and improving the family planning policy.
The State Council argues adjustment to the policy in the face of a steadily declining birth rate. The birth rate has remained relatively low and shows a tendency to fall further. The rate has dropped to between 1.5 and 1.6 since the 1990s, which means each Chinese woman of child-bearing age gives birth to 1.5 to 1.6 children on average. The working population began to drop in 2012 by 3.45 million every year, and it is likely to fall by 8 million each year after 2023.
The population aged 60 and above will reach 400 million and account for one-fourth of the total population in the early 2030s, up from one-seventh now.
“If the current family planning policy continues, the birth rate will continue to fall and lead to a sharp drop of the total population after reaching a peak,” said Li Bin, minister in charge of the National Health and Family Planning Commission.
“It is the right time to make changes: The low birth rate is stable, the working population is still large and the burden of supporting the elderly remains relatively light,” he added.
An increase in birth is expected if the policy changes but will not seriously affect the food supply, public education, health care or employment.
China’s food safety and public service plans are designed to meet the needs of 1.43 billion population in 2020 and 1.5 billion in 2033. Even with the policy change, the total population will reach no more than 1.38 billion in 2015, Li said.
1. Why did the State Council submit the bill?
A. To increase the population of Han nationality.
B. To balance the nature and society.
C. To develop the economy of China.
D. To solve the social population issue.
2.The new policy may have an effect on the following expect _____.
A. public education B. the food supply
C. the divorce rate D. employment
3.What can we learn about the population in China from the passage?
A. After the year of 2023, the population will become less and less.
B. There’s no need to carry out the family planning policy.
C. At the beginning of 2030s the aging problem will be worse than now.
D. In the year 2023, the population may be the least.

Arthur Miller(1915-2005) is universally recognized as one of the greatest dramatists of the 20th century. Miller’s father had moved to the USA from Austria-Hungary, drawn like so many others by the “ Great American Dream”. However, he experienced severe financial hardship when his family business was ruined in the Great Depression (大萧条时期) of the early 1930s.
Miller’s most famous play, Death of a Salesman, is a powerful attack on the American system, with its aggressive way of doing business and its insistence on money and social status as indicators (标志) of worth. In Willy Loman, the hero of the play, we see a man who has got into trouble with his system, Willy is “burnt out” and in the cruel world of business there is no room for sentiment (情绪): if he can’t do the work, then he is no good to his employer, the Wagner Company, and he must go. Willy is painfully aware of this, and at a loss as to what to do with his lack of success. He refuses to face the fact that he has failed and kills himself in the end.
When it was first staged in 1949, the play was greeted with enthusiastic reviews, and it won the Tony Award for Best Play, the New York Drama Critics’ Circle Award, and the Pulitzer Prize for drama. It was the first play to win all the three of these major awards.
