The Ok is shorter THAN the Volga

I was sitting in an arm-chair and watching my sister Alison. She was getting ready for a party. Alison was 15 years (OLDER) than me and she always treated me like a child. Alison took her jewelry box from the table. The box was MADE of wood and had colourful stones on the top. “You know you must never touch it, right?” Alison said. “If the box was mine, I (WOULD ALLOW) you to touch it whenever you wanted,” I answered. Alison said nothing to that. When she put on her jewelry, she looked like a princess. She moved gracefully as if her (FEET) didn’t touch the ground. Alison kissed me goodnight and left. I tried to resist my curiosity but I (COULD NOT). I opened the box. There (WERE) lots of rings, ear-rings, bracelets and necklaces inside. I got them all out. The (ONLY) piece of jewelry I tried on was a silver necklace. After that I lost track of time. Suddenly I (SAW) Alison. She was standing at the doorway and looking at me angrily. I (DID NOT KNOW) what to say. Many years have passed since that night. Now I am a designer – I create clothes and accessories. My sister likes my work very much.

1. "Carbon calculators" can help you to know how much CO2 is produced by you.
2. Almost one ton of CO2 per person may be produced during a flight across the Pacific Ocean.
3. That can be done by buying energy-efficient light bulbs, refrigerators, and other appliances. By installing solar panels, we can make homes and businesses greener.
4. It may be offsetted by walking, riding bicycles, and driving hybrid cars.
5. This article implies the need  of reducing CO2 levels in the atmosphere.
Because, otherwise it may lead to global warming.
