Article: Elephants and people are in competition for space. In much of Africa, elephants are now put in national parks. Elephants suffered a serious and steady decrease in numbers in the 1970s. This was the same time when scientists were beginning to learn a great deal about elephants and their behavior. Studies through the 1980s and into the 1990s showed a lot about their sounds and methods of communication. In Kenya alone, in the 1970s and 1980s, the elephant population decreased from 170,000 to 25,000. The sharp drop in numbers was the result of poachers illegally killing elephants for their ivory. The price of ivory went from $3 a pound to $50 to $100 a pound. Africa became very attractive to poachers. Bull elephants carried the largest tusks , so they were more often killed. With males gone and older females killed by poachers as well, there were many young elephants unable to benefit from the wisdom of the older females and matriarchs, who lead the herds. Kenya took a stand, international trade in ivory was officially forbidden, and $3,000,000 worth of confiscated ivory was burned in Kenya. The following year, only 50 elephants were lost to poachers in Kenya instead of 3,000. But Kenya has the fastest growing human population in the world. People throughout Africa won't tolerate elephants eating their crops and destroying their livelihoods. In South Africa, elephants live behind the fences of national parks. In some parts of Africa, big-game hunters pay a lot of money to hunt elephants. This keeps their numbers down, and the money goes toward conservation. In Kenya, there were some attempts at birth control to keep the elephant population at manageable numbers to reduce conflicts with people. Faced with a growing human population, elephants are losing the battle for space. It's unlikely, though, that they will become extinct. They will live in natural parks that bring tourists to Africa as well as India and other parts of Asia. The money from tourism will help elephants to survive.

Article: So much to do, so little time.So much information, so little time to read.In this age there is more information than ever before.There is not enough time to read everything we want to read.However, you can take in and understand more information in shorter time through speed-reading.This article will not make you read 3,000 words per minute, but it will show you how to increase your speed greatly.You will also learn the basic techniques of speed reading, along with the dos and don'ts of speed-reading. When you first learned to read, you would say the word out loud and sound it out.Then you might whisper the word because people can become annoyed when you read aloud.The stage you are now at is saying the word in your head.Most people tend to read this way.Saying the word in your head will cut your reading speed tremendously . How do you calculate your reading speed? The speed is measured by how many words per minute you can read.Get some reading material, preferably a book.Find out how many words are on the page.Time yourself one minute.Start your timer and start reading.When the timer sounds, stop at once.If you counted 500 words on the page and you read half of the page, then you are probably reading at 250 words per minute. The first thing about speed-reading is looking at the word and recognizing it.Don't say the word in your mind, just look at it and recognize its appearance.Later you will recognize groups of four words or more to increase your speed.This is the first and most important step in speed-reading. The next step is technique.As with any other skill, speed-reading requires technique.You should first be sitting up straight with your book on a horizontal surface, such as a table or desk.Next, should be able to see the entire page.This is necessary if you want to recognize clumps of words.Lastly, _ .It's hard to read with a lot of noise.Find a quiet place to read.This will help your understanding of the text.You need something to guide your eyes while reading.Then right, you should use your hand.Remember when you were little, you would read using your finger.That is a great technique, only now you're using your hand to underline each line.Move your finger smoothly across page.No need to go rush, start out slow.Keep your eyes focused on words as you recognize them while using your hand as a guide.This will increase your speed. The third step is practice.Practice makes perfect.Set time intervals.Read using different techniques, but make sure you understand what you're reading.
Question: Which of the following statements is true according to the text?
Options: (A) Now there is limited information than ever before. (B) Now conditions ask people to use less time to know more information. (C) Now people can read what they like. (D) The less you read, the more time you will spend.

Article: When I first saw the bookAlice in Lace, I thought I was going to like it. And as it turned out, I love it! I love books about life and being a kid. And Alice in Laceis just that kind. It's a humorous book about being thirteen and the problems kids might face. Alice and her friends get a strange assignment from their totally cool teacher, Mr. Everett. It was like playing the game of "Life," but you had to act it out. So Pamela is pregnant, Elizabeth buys a car and Alice gets married. Well, of course, Pamela wasn't really pregnant, but she walked around with a pillow under her shirt to get people's reactions. Elizabeth didn't really buy a car, but she went to the car lot and made the sales guy think she was. The whole class got assignments like these! I would love to do something like that for school. In the book Alice has a lot to think about. "Getting married is hard!" Alice says. She has to plan the ceremony, the honeymoon, find a place to live, pay for furniture and two months' rent and food. Maybe she and her "husband" could work it out -- if they were getting on fine! Although this book was funny, it really made me think about how problems like these could really mess up your life. Take teenage pregnancy for example. How could you have a baby and stay in school? You couldn't find a babysitter every day to stay with your kid. A child really consumes your life. I understand what the teacher was trying to do. He was trying to discourage the class from getting into these problems by giving them a glimpse of life. As someone about to become a teenager myself, I can say sometimes a story makes you think about what's up ahead. Overall, I would say this book is wonderful. My favorite part of the book is discovering that if I like it, there are seven other Alice books I can check out at my local library. I love this book, and I hope you will too.
