Its heavy long tail helps it keep its balance. If it is run after, a large kangaroo can reach a speed of 40 kilometers an hour. One jump may be 8meters long and up to 3 meters high. The red kangaroo is found mainly on the dry grasslands of Australia .It usually travels in small groups. Each group has about 12 kangaroos. When a baby red kangaroo is born, it weighs only 28 grams! After being born, it crawls(爬行 ) through the mother’s fur to her pouch. In hard times, the mother kangaroo can stop the baby from being born till there is enough grass for her to eat. The mother feeds the baby called a “Joey” with milk from her baby. The Joey will spend at least a year in the pouch. If a kangaroo is run after and cannot run away, it will turn and fight. It will lean back on its tail and kick with its hind legs. These legs are very, very strong and have large claws. The front legs are used to hold things, not to box, as you often see in cartoons. Kangaroos can live for up to 20years. A kangaroo never stops growing bigger, so an old kangaroo can be very large. These are probably millions of kangaroos of all types in Australia.

Last Sunday I counted ads for seven kinds of televisions and thirteen kinds of radios in the Atlanta Journal. Besides that, three were pages and pages of ads for Citizen’s Band Radios and tape recorders. Don’t you realize electronic equipment is invading(涌入，侵入 ) our daily life ? Wherever you go you may hear loud music and advertisements over the radio。 this continual noise is ruining our ears. Husbands don’t talk to wives any more。 they are always watching the news or a ball game. Children ruin their eyes with endless hours of watching not only the programs for children but those for grownups as well. And what’s worse, hidden microphones find out about our private lives, and puter keep records of personal information about us. Enough is enough! I think you should limit the amount of advertising of electronic equipment in the Atlanta Journal. Otherwise it will make life unbearable for us all. Mary Cook Atlanta, Georiga ( ). 51.
