Passage Five You may a ready know that hurricanes are major tropical storms that can cause devastating waves, wind, and rain. They happen during “Hurricane Season”, which is from June lst until November 30th in the Atlantic Ocean and from May 15th until November 30th in the Pacific Ocean. A storm progresses through four different stages before it is actually considered a hurricane. First is a tropical disturbance, which has thunderstorms and rotating winds, or what scientists call cyclonic circulation. Next is a tropical depression, which is similar to a tropical disturbance, but has winds between 23 and 39 miles per hour. A tropical storm is the next level, which has stronger wind speeds between 40 and 73 miles per hour. Once winds reach 74 miles per hour, the storm is officially classified as a hurricane. The winds pick up energy from the warm surface ocean water. As a hurricane crosses over land, it begins to dissipate, or break apart and reduce in strength. This is because it is no longer over the warm ocean water that it needs for energy. At this point, a hurricane can still cause a lot of damage because of high winds, rain, and flooding, but unless it makes its way back over the open ocean, it is downgraded from a hurricane back to a tropical storm. The center of a hurricane is called the eye. While most of a hurricane contains dangerously strong winds, the eye is actually a calm area in the storm. When the eye of a hurricane passes over land, people might think that it’s over, but before long the wind and rain increase again as the second part of the hurricane moves through. Can you imagine flying a plane through a hurricane If you’re a hurricane hunter, it’s your job! Hurricane Hunters fly airplanes on weather missions to help the National Hurricane Center make predictions about hurricanes. Pilots determine how fast the winds are blowing, how big the hurricane is, and which direction it’s moving. This helps people to be better prepared for hurricanes as they approach shore.Hurricanes can leave behind lots of destruction. In 2005, Hurricane Katrina ripped through Louisiana, Alabama, Mississippi and Texas. This was the sixth windiest hurricane on record, and it was one of the deadliest hurricanes in history. It took l,833 lives and caused over 76 billion dollars in damages. Many people are surprised to learn that Katrina’s wind didn’t cause most of the damage. The wind had caused levees in New Orleans to break. When the levees broke, water from the Gulf of Mexico rushed into the low-lying land. Over 80% of the city of New Orleans was buried in flood water.Questions 21-25 are based on Passage Five. What would you observe if you were in the eye of a hurricane

Passage Three It has been two decades since the fate of a bashful bird that most people had never seen came to symbolize the bitter divide over whether to save or saw down the ancient forests of the Pacific Northwest. Yet it was not until Thursday that the federal government offered its final plan to prevent the bird, the northern spotted owl, from going extinct. After repeated revisions, constant court fights and shifting science, the Fish and Wildlife Service presented a plan that addresses a range of threats to the owl, including some that few imagined when it was listed as a threatened species in 1990. The newer threats include climate change and the arrival of a formidable feathered competitor, the barred owl, in the soaring old-growth evergreens of Washington, Oregon and California where spotted owls nest and hunt. One experiment included in the plan: shooting hundreds of barred owls to see whether that helps spotted owls recover. Even after all these years since the spotted owl became the cause célèbre of the environmental movement, it is far from clear that the plan is a solution. Advocates on both sides say it will inevitably be challenged, and both sides have expressed frustration with the Obama administration on the issue. The spotted owl is declining by an average of 3 percent per year across its range. While some populations in Southern Oregon and Northern California are more stable, some of the steepest rates of decline are here in Washington. Some study areas in the Olympic and Cascade ranges show annual declines as high as 9 percent. The listing of the spotted owl as a threatened species led to a virtual ban on logging in many older federal forests, inspiring angry lawsuits and threats of violence by rural loggers against owl advocates, who often came from urban areas. “Nothing against the bird, but it’s wreaked a lot of havoc in the Pacific Northwest for the past 20 years,” said Ray Wilkeson, president of the Oregon Forest Industries Council, which represents loggers, sawmills and others in the industry. “A lot of human suffering has resulted from this. Now there’re new threats to the owl that may be beyond anybody’s ability to control.” Although the plan does not map critical habitat — the mapping process is more than a year away from completion, a fact that frustrates conservationists – it proposes expanding protections for owls beyond areas currently set aside. The existing areas were outlined by the Northwest Forest Plan, which was approved a year after President Clinton’s Timber Conference, revised under President George W. Bush to allow more logging and reinstated by the Obama administration. The American Forest Resource Council, a timber industry group, said the plan would impose “massive new restrictions on both federal and private lands.” But supporters say it will provide more wood for mills by increasing forest thinning and restoration work to battle threats like disease and fire that could increase with climate change. The plan would provide timber companies incentives to create potential spotted owl habitat. Officials from the Forest Service and from the Bureau of Land Management, which oversee logging on federal land, expressed support for the plan. While timber advocates question protections for a bird that some say may be bound for extinction, conservationists say that it is too soon to give up on the spotted owl, and that the fight to save it has served broader benefits of the forest, from cleaner water and air to habitat for hundreds of other species, including endangered salmon. “The spotted owl is the icon,” Dr. Forsman said, “but there are a lot of other players in terms of species and protecting biodiversity in these forests.”Questions 11-15 are based on Passage Three. The purpose of the new government plan is to______.
Britain’s most prestigious scientific institution, the Royal Society, will host a meeting for some of the world’s top psychologists. Their aim is to find out why it is that some people’s lives go so right. What is it that makes them happy and fulfilled, while others seem doomed to founder in misery, dissatisfaction and dejection Psychologists have known for some time that optimism is a good defense against unhappiness.“If you are optimistic and you think life is going to get better, it will become a self-fulfilling prophecy,” says Baylis. “You will involve yourself more, you will take more care of yourself. You will figure that if you do more exercise and not booze as much, life will be better.” Positive psychologists believe optimism can be learned, and we can teach ourselves to see a half-empty glass as half-full.“Research on depression shows that one of the biggest causes of depression is ruminating about something that went wrong in the past,” says Baylis.“What happens is you look into the past and think about some event and keep turning it over, saying, ‘I messed up, I messed up,’ and you let it hurt you.” But just as dwelling on negative events can lead to depression, dwelling on things that have gone well can help pick you up.“You have to thank your lucky stars about what goes right on a daily basis. Whenever you get the feeling of being negative about things, just take a moment out and remind yourself of the stuff that has gone well. It could be anything from a conversation to your garden looking nice, or that it didn’t rain on you when you were out on your bike. It’s an extremely powerful technique.” By reminding ourselves what went well instead of what went wrong, positive psychologists believe we can build a buffer against unhappiness, making us better able to take life’s knocks when they come. having high status (Para. 1)

Passage Ten Scientists have been finding evidence of life inside meteorites for well over 100 years — that, or the building blocks of life. The claims of life have proved false every time. It always turns out to be a wishful interpretation of chemicals, minerals and tiny structures inside the meteorite that could be the fossilized long-dead bacteria — but almost certainly aren’t.
