【题目】 Dinosaurs(恐龙)once lived on the earth for a long time. They suddenly disappeared millions of years ago. What happened to themThat's still a mystery. People never stop searching for the answer.

Some US scientists say it is because there were not enough male(雄性的)dinosaurs. They got this idea after researching crocodiles(鳄鱼).

Mother crocodiles lay eggs and later baby crocodiles come out. The local temperature decides the sex(性别)of the baby crocodile. When the eggs are at a temperature of 26 to 30 ℃,the babies are all girlswhen the temperature is 30 to 34℃,there are both boys and girlswhen it is 34Cto36℃,only boys are born.

Dinosaurs' babies also came from eggs. So scientists have given us a new picture: millions of years agoit suddenly became very cold. Almost all dinosaur babies were girls. There were fewer and fewer male dinosaurs. Mother dinosaurs could not give birth to more babies. Finallythese powerful animals disappeared.

【题目】 Do you often run outdoors to keep healthyHave you ever thought about how running helps to clean up the earthSometimes a creative mind can bring us a win-win(双赢)situation.

Plogginga new way to exercisebegan in Sweden(瑞典). The name “plogging” comes from two words-the Swedish(瑞典的)word "plocka”which means" to pick up(捡起)and the word “jogging”which means" “to run slowly”. A Swedish man called Erik started the movement. He saw rubbish here and there when riding to work each day. He became worried about the dirty environment and decided not to go to work by bike any more. Insteadhe began to run to work and pick up the rubbish at the same time.

To his joymore and more people followed him and soon plogging became popular.

Many people choose plogging instead of just jogging because they think plogging is a good way to help clean up the earth. Sometimes rubbish is difficult to collect because it may scatter all around. But if the runners pick up the rubbish on the wayit is quite different. After allmany hands make light work. Another reason is that plogging burns more calories(卡路里). According to a researchplogging for 10minutes burns 48 calorieswhile usual jogging for 10 minutes burns about 39 calories.

Everyone on the earth should play a part in cleaning it upIt's time for us to take action together. So readyLet's plog tomorrow
