By the middle of the 19th century, newspapers were becoming the primary means of spreading and receiving information. The period between 1890 and 1920 is known as the "golden age" of print media. Broadcast radio came onto the media scene in the 1920's. Newspapers were forced to re-evaluate their role as society's primary information provider. Like the new media technologies of today, the development of a low-cost, convenient media source produced results that radio would greatly affect the newspaper industry. No sooner had newspapers adapted to radio than they were forced to re-evaluate themselves because of a new and more powerful medium: television. Between 1940 and 1990, newspaper sales in America dropped from one newspaper for every two adults to one for every three adults. Some newspapers, like USA Today, responded to the technological advancements by using color1 and the "short, quick and to the point" stories that are usually featured on television. The technological revolution of today is creating new challenges and opportunities for traditional media. Never before has so much information been so accessible to so many. By the end of the 1990s, about 700 traditional media had websites; today there are thousands. The amount and speed of information on the Internet is _ , but it has not signalled the end of the newspaper's existence . Newspapers in print remain a popular and powerful medium for the reporting and analysis of events that shape our lives. It is reported that one billion people in the world read a newspaper every day! Radio had a great influence on the newspaper industry because _ . A) it was easier and cheaper to receive information by radio B) nobody supported the development of the newspaper industry C) newspapers were not a primary information provider any longer D) many people were too poor to buy newspapers in the early 20th century

Joseph Banks was born in 1743,the only son of a wealthy land-owning family. From an early age, he was interested in natural history, and in particular, botany. In the early 1760 's he chose to make this dream to the full. In 1766 he travelled to Newfoundland and Labrador to collect plants, animals and rocks. For him, joining Captain Cook' s 1768 expedition to Tahiti was like a present- day scientist being given the chance of a trip to another planet, a chance to study new plants in unknown lands. They made collections and observations in South America, Tahiti and New Zealand before reaching Australia. His major landfalls on the eastern coast of Australia were at Botany Bay and at the Endeavor River. He thought collection of plants was grown so large that it was necessary that some extraordinary care should be taken of them in case they should destroy. The plant material collected and sorted on the voyage was huge, with the herbarium specimens about 1300 new species. After returning from this voyage, Banks travelled to Scotland, Wales, Holland and Iceland, collecting more and more _ . Among many other activities, without thinking running out of his money, he controlled the Royal Botanic Gardens, Kew and was a Trustee of the British Museum. Although Linneaus' suggestion of naming the new country of Australia "Banksia" was not accepted, Banks' name was bestowed upon Australian plants and he made his mark upon Australian history in other ways, later he became the well-known authority on matters relating to New South Wales. He had a great impact on the study of natural history in both Britain and Australia. He died in 1820. When Banks was young _ ;. A) he was only fond of botany B) he travelled to many places C) his family was not very rich D) he hadn't much dream about his future

Ques: The sun is a huge, hot, bright star. It is important because without it there would be no life on Earth. The sun gives us light and heat. All living things need light and heat from the sun to live. Plants need light and heat to grow. They use the light from the sun to make food. We cannot make our own food, but plants can. All the food we eat comes from plants in a food chain which starts with the sun. For example, Animals need sunlight, too. Just like us, their food comes from a food chain which begins with the sun and the plants. sun- leaf- caterpillar -bird sun- seaweed -small fish- whale Sunlight means we can see during the day. If there was no sun, it would be dark all the time. Even when the sky is cloudy, the sunlight is very strong and it shines through the clouds. Which words tell us what the sun is like? A) Huge. B) Hot. C) Bright. D) All above.
Ans: A
Ques:Something's not quite right with the climate.While global CO2emissions have continued to swell, the global temperature rise has leveled off.Meanwhile, satellites and other observational tools indicate that the net heat retained by the planet has continued to increase, and that excess energy should be pushing up surface temperatures.But it's not. In fact, up to half the heat energy that was expected to fuel global wanning since 2003 has gone " missing.M Kevin Trenberth and John Fasullo of the National Center for Atmospheric Research ( NCAR) wonder where that heat may have gone--and what it could mean for the future of the climate. One possibility is that some of our measurements could be off.Although scientists have a lot of confidence in their ability to measure CO2buildup and the energy balance in the atmosphere--the data used in the measurements comes from multiple sources, all of which, Fasullo says, "tell the same story"--our data on ocean temperatures isn't as good."Keeping track of temperature over the whole oceans isn't that easy," says Fasullo. So, it is likely that the missing heat is being trapped deep in the ocean, well below the 900m to 1,500m range of our surface sensors.But despite their vastness, the deep oceans have a limit, says Fasullo, who thinks they won't behave as a heat sink over the long term."That's not what we've seen over long time scales in the past," he says."We clearly know the ocean can't absorb the heat indefinitely. Overall, the missing heat doesn't change expectations for future climate change, because the heat won't stay missing forever.Eventually it will resurface and impact the climate system, and the recent and deceptive reprieve from rapid warming we've enjoyed will come to an expected end.When that will happen is unknown, but better science can give us a clearer idea."At the end of the day, the system will come back to balance, and that suggests temperature will end up increasing," says Fasullo.So it's still up to us to do something about it. According to Fasullo's report, we can conclude that _ . A) the measurements of heats in ocean may not be exact B) the global temperture rise has dropped down C) it still needs higher technical tools for measuring missing heat D) scientists have enough confidence in measuring CO2emissions
