New research，however，has showed that the worlds largest land animals have a secret trick of controlling their body temperatures.Scientists have long been puzzled by temperature regulation(调节)in elephants. Generally，animals with large bodies tend to hold more heat because，compared to their size，they have a small surface area for heat to escape from. Elephants，with their heavyweight frames，would appear to be at a disadvantage in the heat of their African and Asian habitats，especially because they have thick fur to protect them from bushes and trees.Scientists thought that these creatures，which weigh up to 13 tons when fullygrown，grow large ears to help them stay cool. The skin on the ears is thinner，so blood which flows into them cools down more easily. But findings by researchers at two universities in Vienna have showed that elephants are also able to cool down by increasing the blood flow to skin patches(斑) in other parts of their bodies.The researchers studied six African elephants at Vienna Zoo as they moved between outdoor and indoor environments to see how the temperature on their skin surface would change. They found up to 15 “hot spots” all over an elephants body surface，in addition to large patches on the ears. The study shows how these patches expand as the air temperature increases and more blood flows nearer to the skin surface. Other experiments show that elephants in the wild use the same “windows” to control their body temperature.Elephants have two additional ways to stay cool: flapping(拍打)the ears and bathing. Together with these tricks，the skin hot spots allow the animals to keep their body temperature always at about 36 degreesone degree less than humans.21. What can we know about the elephants?A. They have thick fur to protect them.B. They live in cool areas in Africa and Asia.C. They can weigh up to 3 tons when fullygrown.D. They are afraid of water and rivers.22. The function of the thinner skin on elephants ears is to_.A. control their body temperature B. help hold more heatC. drive away insects D. keep sensitive hearing23. The new research_.A. studied six Asian elephantsB. studied elephants in a zoo and in the wildC. aimed to discover the elephants disadvantagesD. proved that scientists earlier beliefs were totally trueBMySpace，the social networking website，is different from other websites which only provide stories about other people. MySpace is a place that allows you to broadcast your own stories and personal information to as many people as you like. Started two years ago，it is a big source of information for and about American kids.Teenagers and their parents feel very different about it. Teens are rushing to join the site，not sharing their parents worries. It signals yet another generation gap in the digital era.For teenagers，it is reliable network to keep in touch with their friends. They will often list their surnames，birthdays，afterschool jobs，school clubs，hobbies and other personal information.“MySpace is an easy way to reach just about everyone. I dont have all the phone numbers of my acquaintances. But if I want to get in touch with one of them，I could just leave them a message on MySpace，”said Abby Van Wassen. She is a 16yearold student at Woodland Hills High of Pittsburgh，Pennsylvania.Parents on the other hand are seriously concerned about the security problems of MySpace. “Every time we hold a parents meeting，the first question is always about MySpace，”said Kent Gates，who travels the country doing Internet safety seminars(研讨会)The National Centre for Missing and Exploited Children has received at least 288 MySpace related complaints，according to Mary Beth Buchanan，a lawyer in Pittsburgh.“Your profile on MySpace shows all your personal information to anyone on the Web. And MySpace even lists this information by birthplace and age. Its like a free checklist for troublemakers and it endangers children，” Buchanan said.24.
