First of all, the aging problem make people become more pressed than before. Because the young people and middle-aged people are tackling their children’ growing and how to look after their parents which give them more responsibilities than in the past. For those people, in order to support their big family, they sacrifice their leisure time to do a lot of work so that they can get much money. For example, my uncle Leo devotes himself to the his work and he always have no much time to eat dinner with his family. Why does he do like this, because he has two children and his parents. When he earns money, he will deposit much money in the bank that is using to pay fees for his children and buy some important things for his parents. In this world, a lot of people resemble my uncle, they lose their health and time to support the family and it also cause them become unhappy probably.

Plus, the competition between workers is more cutthroat than before. The risk that will be fired force people into doing their work hardly. Many people, especially for young people, they have to sacrifice their free time to learn more working skills in order to protect their working position. For instance, my brother Joe is an accountant in a company and many young people are the same as him.So he improves his ability on accounting and gets the higher certification in order to preserve his job, but the learning time is difficult, he has class after work and he back home at night. I think it is hard for him because he has no time to do what he likes and stay with her girl friend.

At last, those two problems cause why people are not happy now and I truly hope that the young and middle-aged people can solve this problem and relax themselves.

The reading passage talks about a fossil skeleton of a dinosaur called Sinosauropteryx which preserved in volcanic ash and it discovered in Liaoning. The fossil included a pattern of fine lines surrounding the skeletal bones and some paleontologists explain the lines as evidence that the Sinosauropteryx had feathers. But, in the listening part, the professor disagree with that because the Sinosauropteryx was a feathered dinosaur.

Firstly, in the reading passage, the author asserts that the critics points out that the fine lines may not even represent functional structures of living dinosaur because after the animal died and was buried in volcanic ash and the skin may decomposed into fibers so that the well-preserved lines formed by fibers will be misinterpreted as evidence of feathers. In contrast, the professor thinks that it is unlikely that the lines are formed by the decomposition of dinosaur’s skin, because they do not see any decomposition in the fossil of other animals buried in the same place.

Secondly, the reading passage asserts that the lines surrounding the skeleton are much likely to be fossilized remains of frills than remains of feathers. However, in the listening part, the professor says that the analyses indicates the Sinosauropteryx structure contained beta so that the structure is feather not fills.

Thirdly, the author claims that the lines do not represent feathers, because the structure represented by the lines in the dinosaur fossil were mostly located along the backbone and the tail of animal. However, the professor refutes that feathers that this dinosaur uses for display Because the feathers can be used for other function.
