Polar bears are suffering in a 1(warm) worldthan ever before. Polar bears live in environments too cold for most 2(animal). During much of the year, they live and hunton the frozen Arctic sea ice. Nature has prepared 3for the cold conditions. But nothing has prepared the bearsfor the danger that 4(threaten) the only homethey know. The polar bears' world is melting. Studies show that thepolar ice has reduced by 9. 8% every 10 years 51978.Now about 20,000 to 25,000 polar bears live in the Arctic. Polar bears depend on the sea ice for their 6(survive). "The sea ice is more than just this platform that the bears walk over,wsays Andrew Derocher, 7scientist who studies North American polar bear populations, "8it,they can’t exist.”Some melting and refreezing of the polar ice is natural. 9 in a wanner world,these cycles speed up,and bears have less time to hunt. 10(normal), they have three months in the spring when they gain more weight.The extra fat is used later,when the bears are not actively hunting.
The man who found an easier way for people to cut grass and weeds died in Houston on June 25th, He was 85 years old. George Balias was born in Louisiana. He joined the military at 17. He served in World War II and the Korean War. After the military, he became a dance teacher in the dance school. In the 1950s,he built a dance studio of his own in Houston. People called it the biggest in the world. But Mr Balias sold the studio in 1964. By the early seventies the was on to the next big thing. The idea had come to him at a car wash. He watched the needle—like bristles(刷子毛)of the brushes as they went round and round against his car. Could a similar idea be used to cut grass in places out of reach of someone pushing a lawn mower(割草机)? To find out,he placed lengths of fishing line through holes in a tin can. He attached the can to the spinning (旋转) part of a grass machine. The result? A revolution for millions of people who cut grass for a living or just to keep their neighbors happy. George Balias became known as the"Weed King". As he once told the Houston Chronicle ,"A Weed Eater comes along once in a lifetime, "His invention now still works well in corners and along walls and fences.

I was selling tickets and asking for $1.00 donations(捐款)for our youth programs to help the children without parents in Minsk. "Donate a dollar for youth programs and receive a ticket for a $1.50 hot dog!" Some donated a dollar and received a ticket; others donated more. Some simply do-nated without taking tickets,sometimes even $5, 00 or $10.00.I was touched. So I continued my work with more energy. Then, a group of Spanish farm workers entered the store, I knew they were poor and might not even understand what I was doing. So I decided just to let them walk by me and didn’t say anything. However i after they disappeared into the store,I thought again. I had seen these men working hard on the farm under the sun of a very hot summer day. I knew they needed every dollar. But I realized that they deserved the same respect shown to every local citizen. They also deserved the chance to donate to such a program, even if they had little! But what could I do? My Spanish was very poor, but I had to do it. I could never expledn in Spanish. But I know two little words. When they came out of the stored walked towards them with those two little words: “Por favor”(Piease). Nothing more.
