Article: Giant pandas are now extremely rare. Their number is less than 1,000 in the wild. The hunting of pandas has been banned for many years, so this is not the problem. Destruction of its habitat, when areas are cleared for growing crops, is one of the main reasons for panda's decline . Another reason is that the bamboo on which they mainly feed, is dying back. The pandas find it difficult to move to new feeding areas. As the bamboo disappears, the pandas simply starve to death. Bamboo is a poor source of food, and pandas have to eat up 45kg of it every day, a process that takes them up to 16 hours. The process goes on day and night, with the pandas in a constant cycle of eating for eight hours and sleeping for four. They can eat other foods, but will rather starve than change their diet when bamboo is scarce. Giant pandas are very good climbers, and use this skill to escape from the enemy. The giant panda lives alone for most of its life, only coming together with another of its species for long enough to mate. A newborn panda baby is born hairless and blind, is about 15cm long and weighs only 100g. The baby will stay with its mother for about 18 months, until it is able to set up its own territory Chinese and American scientists are studying giant pandas and their habits in order to put in place a major conservation programme. Zoos around the world are taking part in panda breeding programmes. There is still hope that with human's help, the giant panda can survive in the wild.

Article: Imagine life without the Internet -- not being able to chat with your friends or look up information for your homework or research project. That is the reality for nearly two-thirds of our world's population, either because they cannot afford WiFi access or are located in remote, inaccessible areas. Now Google has decided to do something about that. Google's Project Loon will attempt to send balloons high up into our earth's atmosphere in 2015. Each balloon will be equipped with a mini computer and a WiFi radio that will send Internet signals over the places it is floating over. The network equipment on Google balloons will communicate with a special antenna attached to each user's home. These antennae are in turn connected to a local Internet Service Provider. Each balloon will also communicate with each other to hand over signals as one floats out of an area, and another floats in. The balloons are 15 meters wide and made of a material that is three times thicker than the plastic bag at the supermarket. This helps them defend themselves against cold temperatures and changing air pressure. Google balloons will circle the earth at a height of 20 kilometers-- in a layer of our atmosphere known as the stratosphere . This is higher than the altitude at which planes fly. Once the balloons reach the desired altitude after being released from the earth, they will ride on air currents. What keeps these balloons from flying away? They will be controlled by people at the Project Loon command center. A pump operating on solar power will fill the balloon with gas to raise it or let gas out to lower it, based on instructions. This allows the balloon to float on different air currents which are moving either clockwise or anti-clockwise. There is no doubt that this technology can bring education to many children, weather information to farmers, and communication to natural disaster areas. However, one big question remains -- will some countries be comfortable with balloons above their heads? There could be concerns about spying and other problems.
Answer: Helping us learn more about the earth's atmosphere.

Article: I had a very special teacher in high school many years ago whose husband unexpectedly died of a heart attack. About a week after his death, she shared some of her views with a classroom of students. As the sunlight came in through the classroom windows and the class was nearly over, she moved a few things aside on the edge of her desk and sat down there. She paused and said, "Before class is over, I would like to share with all of you a thought that is unrelated to class, but which I feel is important. Each of us comes to this world to learn, share, love, appreciate and give. None of us knows when this fantastic experience will end. It can be taken away at any moment." Her eyes beginning to water, she went on: "So I would like you all to make me a promise. From now on, on your way to school, or on your way home, find something beautiful to notice. It doesn't have to be something you see. It could be a _ of freshly baked bread from someone's house, or it could be the sound of the wind slightly rustling the leaves in the trees..." The class was completely quiet. We all picked up our books and left the room silently. That afternoon, I noticed more things on my way home from school. Take notice of something special you see on your way home today. Go barefoot on the beach at sunset. For as we get older, it is not the things we did that we often regret, but the things we didn't do.
Answer: To ask us to appreciate every moment of our life
