　　　Unlike modern animal scientists, dinosaur scientists cannot sit on a hillside and use telescopes to watch dinosaurs in order to know how they lived and whether they were good parents. Instead, they have to search hard for information from dinosaurs' fossils(恐龙化石) because dinosaurs died out millions of years ago.

　　　It's very difficult for the scientists to reach an agreement because different results can be got from the same fossils. Many fossils of the same kind of dinosaurs have been dug out from one place. They might have formed when an entire group of dinosaurs got stuck(陷入)all at once. Or they might have been the result of dinosaurs getting stuck one after another over a course of a few centuries. Thus we can say that dinosaurs might have in the first case lived in big groups and in the second lived alone.

　　　Though there are two different results, dinosaur scientists now generally agree that at least some kinds of dinosaurs lived in big groups. "That's pretty much settled at this point." Says Paul Sereno. A kind of dinosaurs called Sauropods left behind tracks in the western United States that appear to run north and south, suggesting that they even moved long distances together.

　　　As to whether dinosaurs cared for their young, dinosaur scientists have turned to the closest living relatives of dinosaurs ― birds and crocodiles ― for possible models. Birds give a lot of care to their young, while crocodiles just help their young to the water. The discovered fossils of dinosaurs sitting on their eggs and staying with their young suggest the parents were taking care of their babies, but we still cannot say that all dinosaurs did the same.

　　　There is still a long way to go before the above questions could be answered. Dinosaur scientists will have to find more proof to reach an agreement.

　　　8．Dinosaur scientists can get information directly by .

　　　A． studying dinosaur fossils B． examining modern animals

　　　C． watching dinosaurs D． using telescopes

　　　9．What is pretty much settled according to Paul Sereno?

　　　A． Half of the dinosaurs lived alone. B． Most dinosaurs moved long distances.

　　　C． Many dinosaurs settled in the north. D． Some dinosaurs lived in big groups.

　　　10．Which of the following is true according to the paragraph?

　　　A． Birds hardly pay attention to their young.

　　　B． Baby crocodiles can look after themselves well.

　　　C． Some dinosaurs took care of their young.

　　　D． Birds and crocodiles take good care of their young.

　　　Most Valuable Possessions on Earth

　　　Marie was a single mother of two children in a rural Missouri community. 11． She also dedicated much spare time to numerous charities and community projects.

　　　Then one day Marie received some shocking news from her doctor. She had cancer, and it was spreading rapidly. 12．

　　　Soon , Marie witnessed what she had always known: although she was not financially wealthy, she already had the most valuable possessions on earth. Hundreds in her community and surrounding areas teamed up to help her and her family.

　　　Many people she had touched in caring ways demonstrated appreciation for Marie's life. 13． However, she lived long enough to feel the love of those she had cheerfully served.

　　　The spirits of love and gratitude multiply(增加) when they are shared. 14． Giving selflessly was a value that Marie displayed all her life, and her spirit of giving lived after her in those who knew and loved her.

All her life, Marie had demonstrated（演示） the truth of this simple principle : 15． Rather, it is an attitude that comes from appreciating what we already have. We can find the happiness we seek if we will
