Starting in l972,the National Park Service established a policy for forest fires calle Natural Burn.It was acknowledged that some forest fires,such as those caused by lightning were necessary for forests to maintain balanced ecosystems,so the fire should be allowed to burn.However, a big fire in Yellowstone National Park in l988 caused this policy to be abandoned since the fire was initially allowed to burn yet soon out of control.As a result,the fire of l988 destroyed much of Yellowstone,which is America's oldest and most beloved national park.Massive areas of plants were destroyed,and large empty spaces and acres of burned and blackened trees greeted visitors.The rivers and streams were choked with ash,and the ecosystem of the park was changed beyond repair. In addition,great numbers of animals were killed by the fires that bumed out of control. The fires were driven by high winds,moving as many as ten miles a day.Many small animals died in the flames.The fires' rapid advances gave the wildlife little chance to escape. Even today,few of these small forest animals have returned to live in the park. In the years immediately following the fires,the numbers of visitors declined rapidly.No one was interested in seeing a blackened and treeless park on vacation.Yellowstone had previously been famous for its amazing views and unique geological formations such as the geyser Old Faithful. But now its reputation as America's wonder is damaged permanently. Natural Burn was adopted because some forest fires were A) hard to put out B) started by lightning C) good for the balance of nature D) approved by National Park Service

Telepathy: Mind-to-mind Contact Telepathy is the ability to communicate without the use of the five senses (sight, hearing, touch, smell, taste). It's an instinct which can be woken up in times of emergency or need. When we feel that something is happening or about to happen by instinct, we're using resources within the unconscious mind. When the resources of two persons' unconscious minds link together into the same frequency, we call it Telepathy. We can either send or receive Telepathy. If you know who is calling before you answer the ringing phone, you are probably a good receiver. If you think of a person and he/she calls you, you are most likely to be better at sending. You can easily put your abilities to the test. Think of somebody and will him or her to contact you. Be patient. The other person may not be a good receiver, but they should contact you much earlier than would normally be expected. Or whenever the phones rings, but try "feeling" who is contacting you. Don't guess, but try to feel it with your mind. However, if neither of these work for you, that doesn't mean that you have no ability of telepathy. As mentioned earlier, telepathy is most likely to turn up in case of emergency. Telepathy dreams often contain telepathic messages. Two people may both dream of the other and find that their dreams had a clear connection. These people are probably linking to each other's unconscious mind. Telepathy & Relationships. The more people spend time together, the more likely they are to be able to link up to the other's mind, especially when separated. There are two reasons for this. One is that they understand the other's mind through time spent together; the other is that there is usually a strong desire to communicate. A mother will often sense that her child is in danger. This is due to the child's eagerly wanting his or her mother, knowing that this person who would always want to be there for them, and the mother's deep desire to protect her child from harm. You're better at sending than receiving Telepathy if you _ . A) can tell who knocks at your door B) can feel your mom is in danger C) receive a friend's call as you wish D) dream of a friend dreaming of you

Q: When it comes to protecting the privacy of their children, U.S. parents give social networks a failing grade. According to a recent survey, three out of four parents believe social networks are not doing a good job of protecting kids' online privacy. The survey was conducted for Common Sense Media, a nonprofit organization devoted to helping families find the right way to deal with the world of media and technology. Ninety-two percent of parents said they are concerned that children share too much information online, and 85 percent said they are more concerned about online privacy than they were five years ago. In other findings, Common Sense Media found that 68% of parents are not at all confident in search engines keeping their private information safe and secure and 71% of parents said the same about social networking sites. The survey found a great deal of concern about the online geo-location services which find and show the exact position of somebody through the net. Ninety-one percent of parents said search engines and social networking sites should not be able to share the physical location of children with other companies unless the parents approve. "The survey results present a clear divide between the industry's view of privacy and the opinion of parents and kids," Common Sense Media CEO and founder James Steyer said. "American families are deeply worried about how their personal information is being used by technology and online companies, yet the companies appear to be keeping their heads deep in the sand," Steyer said. IT companies need to step up but parents, children, schools and government also need to do more, he said. "Parents and kids have to educate themselves about how to protect their information," he said. "Schools should teach all students and their parents about privacy protection." "And finally, policymakers have to update privacy policies for the 21st century," he said. According to the survey, more than 60 percent of parents want the US Congress to update online privacy laws for... Which of the following may be the best title for the passage? A) US Congress to Update Privacy Policies for 21st Century B) Common Sense Media Warns Against Social Networks C) US Parents Want Better Online Privacy Protection for Kids D) Worry Grows for Problems Caused by Social Networks

"If I rest, I _ "----would be an excellent motto for those who are troubled by the slightest bit of idleness.Even the most hard-working person might adopt it with advantage to serve as a reminder that, if one allows his abilities to rest, like the iron in the unused key, they will soon show signs of rust and, eventually, cannot do the work required of them. Those who would attain the heights reached and kept by great men must- keep their ability polished by constant use, so that they may unlock the doors of knowledge, the gate that guard the entrances to the professions, to science, art, literature, agriculture--every department of human endeavor. Industry keeps the key bright that opens the treasury of achievement.If Hugh Miller, after toiling all day in a quarry, had devoted his evenings to rest and recreation, he would never have become a famous geologist.The celebrated mathematician, Edmund Stone, would never have published a mathematical dictionary, never have found the key to science of mathematics, if he had given his spare moments to idleness, had the little Scotch lad, Ferguson, allowed the busy brain to go to sleep while he tended sheep on the hillside instead of calculating the position of the stars by a string of beads, he would never have become a famous astronomer. Labor defeats all--not inconstant, or ill-directed labor; but faithful, persistent, daily effort toward a well-directed purpose.So industry is the price of noble and enduring success. By saying "Those who would attain the heights reached and kept by great men must keep their ability polished by constant use", the author means _ . A) great men keep their ability polished B) those who use their ability constantly would attain the great height C) those who want to get great achievements must practice their ability constantly D) great men polish their ability to reach their height
