Article: Blue whales are the largest animals ever known to have existed on the planet, and they can grow to a length of 100 feet and weigh more than 330,000 pounds. But recently researchers have found that these whales are on the move and they have migrated (moved) from California waters to areas off Canada and Alaska for the first time since commercial whaling ended in 1965. The researchers identified 15 blue whales that have appeared off the coast of British Columbia and the Gulf of Alaska since 1997. Four of these whales were recognized as ones that were once sighted off California shores, suggesting that the whales are returning to an old migration pattern between the coasts. Before commercial whaling began in the early 1900s, blue whales were found widely throughout the North Pacific and California waters. But from the 1920s to the 1960s, whaling severely reduced the whale populations. Blue whales never recovered in the Northern Pacific, making sightings in this area rare. However, much larger groups of whales have been observed close to California since the 1970s. The scientists had previously thought that the California population was separate from the population that had historically lived in North Pacific waters. But the current study shows that whales off the coast of British Columbia and the Gulf of Alaska are likely part of the California population.[:] To identify the blue whales, the researchers looked at photos of _ taken in the North Pacific Ocean and compared them with a library of blue whale pictures taken along the West Coast of the United States and Southern Pacific. Up to now, the researchers are not quite sure why the whales are changing their migration patterns, but they suspect that the whales may be following their food moving farther north by the changes in ocean conditions. Question: What might make blue whales migrate according to the researchers? Options: A: Commercial whaling. B: Food resources. C: Weather conditions. D: Life reproduction.

Read the article and select the best answer. Article: Earth Hour is organized by WWF. With almost 5 million supporters and a global network in over 100 countries, it's one of the world's largest and most respected independent conservation organizations. WWF's mission is to stop the degradation of the Earth's natural environment and build a future where people live in harmony with nature. Earth Hour started on March 31st, in 2007 in Sydney, Australia when 2.2 million individuals and more than 2,000 businesses turned their lights off for one hour to take a stand against climate change. Only a year later Earth Hour had become a global movement with more than 50 million people across 35 countries participating. Global landmarks such as the Sydney Harbour Bridge, CN Tower in Toronto, Golden Gate Bridge in San Francisco, and Rome's Colosseum, all stood in darkness, as symbols of hope for a cause that grows more urgent by the hour. In March 2009, hundreds of millions of people took part in the third Earth Hour. Over 4,000 cities in 88 countries officially switched off to pledge their support for the planet, making Earth Hour 2009 the world's largest movement to stop global climate change. On Saturday 27 March, Earth Hour 2010 became the biggest Earth Hour ever. A record 128 countries and territories joined the global display of climate action. Iconic buildings and landmarks from Asia Pacific to Europe and Africa to the Americas switched off. People across the world from all walks of life turned off their lights and came together in celebration and contemplation of the one thing we all have in common--our planet. Earth Hour will continue to be a call to action to every individual, a call to stand up, to take responsibility and lead the global journey to a sustainable future. Question: What is the main purpose of Earth Hour? Options: A: To fight against pollution. B: To save electricity effectively. C: To stop climate change. D: To support WWF's work.

Ques: Read the article and select the best answer. Article: At least eight babies in East China'sprefix = st1 /AnhuiProvincehave died since last year. they died of serious deficiency disease which happened to them because of fake milk powders. More than 100 other babies in Fuyang, mostly between three and five months old, are still in poor nutrition after drinking different kinds of cheap milk powders produced in North China's Inner Mongolia Autonomous Region, Northeast China's Heilongjiang Province and Beijing. The baby victims were born healthy, but they became thinner and thinner, and had large heads for their bodies after fake milk powders were fed to them. "My girl, the first child of mine, died when she was only four months old after drinking the 'Haobaobei'milk powder."said Zhang Linwei, a 32-year-old villager of the Wangzhuang Village in Fuyang. Zhang found that his daughter got ill after the girl didn't want to drink the milk powder any more half a month before. "Before that , I though my daughter's face was becoming fatter and fatter because she was fed well and grew fast."the baby's father said. The girl died nine days later after she was sent to hospital and all of the family's savings were spent on her medical treatment. "It is like a terrible dream. I never thought that my baby would _ like this ."he said. Zhang said he tried to telephone and write to the producer of the milk powder by the address on the packing bag but never made it. "The fake milk powders only have 5-6 per cent protein and the lowest is has only 1 per cent. For babies, drinking such fake milk powder is no different from drinking water,"Zhang Fangjun, said a medical expert with the Fuyang People's Hospital. "Such so-called milk powders cannot afford any nutrition for babies' growth," Zhang said. Question: Zhang Linwei_. Options: A: found her first daughter was killed by 'Haobaobei' milk powder B: didn't' know what caused her first daughter's death at first C: got a lot of money from the producer of the milk powder D: asked the reporter to give him a hand
Ans: B

Ques: Read the article and select the best answer. Article: The behaviour of a building's users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions by 80 percent by 2050, part of which will be achieved by all new homes being zero-carbon by 2016. But this report shows that sustainable building design on its own -- though extremely important- is not enough to achieve such reductions: the behaviour of the people using the building has to change too. The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency , _ instead focus on architectural and technological developments. 'Technology is going to assist but it is not going to do everything,'explains Katy Janda, a UKERC senior researcher,'consumption patterns of building users can defeat the most careful design. 'In other words,old habits die hard, even in the best-designed eco-home. Another part of the problem is information. Households and bill-payers don't have the knowledge they need to change their energy-use habits. Without specific information,it's hard to estimate the costs and benefits of making different choices. Feedback facilities, like smart meters and energy monitors,could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters. Social science research has added a further dimension ,suggesting that individuals'behaviour in the home can be personal and cannot be predicted whether people throw open their windows rather than turn down the thermostat , for example. Janda argues that education is the key. She calls for a focused programme to teach people about buildings and their own behaviour in them. Question: The information gap in energy use _ . Options: A: can be bridged by feedback facilities B: affects the study on energy monitors C: brings about problems for smart meters D: will be caused by building users' old habits

A
