Unlike modern animal scientists , dinosaur (恐龍) scientist cannot sit on a hillside and use telescope to watch dinosaurs in order to know how they lived and whether they were good parents .    71    .

It’s very difficult for the scientists to reach an agreement because different results can be got from the same fossils(化石) .   72     . They might have formed when an entire group of dinosaurs got stuck 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 .

    73     .  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 .     74    .  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 .

75     .  Dinosaur scientists will have to find more proof to reach an agreement .

A. There is still a long way to go before the above questions could be answered .

B. Though there are two different results , dinosaur scientists now generally agree that at least some kinds

     of dinosaurs lived in big groups .

C. Birds give a lot of care to their young , while crocodiles just help their young to the water .

D. Many fossils of the same kind of dinosaurs have been dug out from one place .

E. Half of the dinosaurs lived alone .

F. Birds hardly pay attentions to their young .

G. Instead , they have to search hard for information from dinosaur’s fossils .

     Weddings are so important in China that couples are willing to fork out about 20 times their monthly
income on getting hitched and everything that comes with it.
     China's newly-weds in cities spend 126,600 Yuan (16,600 U.S. dollars) on average in 2006 when getting
hitched, Thursday's Chongqing Youth Daily reported, citing a recent survey by the Ministry of Commerce.
     An analysis of 60,000 couples living in cities showed that about 64 percent of the spending went on house
decoration, furniture and household appliances and the rest was spent on the wedding, such as the ceremony,
photography, wedding dresses and feast.
     The survey said the wedding expenditure was only a small share of the overall marriage cost as most
Chinese young couples in the cities tended to buy an apartment and a car before tying the knot.
     The survey said that about 81.6 percent of the newly-weds admitted that they had got economic support
from parents as their monthly income on average was only about 6,240 yuan.
     The survey also showed that about 88.4 percent of the newly-weds chose having wedding photography
as a priority and 78.74 chose hosting a wedding banquet.
     In contrast, young couples in the countryside spent about 40,000 yuan on average on marriage-related
issues, less than one third of their city peers, according to the report.
     About 8.49 million couples got married in China in 2006.

     The population of the United States is growing older and will continue to do so. According to a report,
39 million Americans will be 65 or older by the year 2010, 51 million by 2020,and 65 million by 2030.
      The "graying" of the United States is mainly due to the fact that people in the U.S. are living longer. As
a matter of fact, the number of U.S citizens 85 years old and older is growing six times as fast as the rest
of the population. It is also largely due to the old- growing of the "baby boomers", the generation born after
World War Ⅱ. In 1957,over 4.3 million babies were born. More than 75 million Americans were born between
1946 and 1964,the largest generation in U.S. history. In less than twenty years, millions of them will become
elderly people.
      The "graying" of the U. S. will greatly affect the nation's family and workforce. One likely development
will be a gradual change in the family unit; it will move away from the nuclear family and towards a
multigenerational family. The other likely development will be a change in the proportion (比例) of the nation's
workforce. In 1989 there were 3.5 workers for every person 65 or older; by the year 2030, there will only be
2 workers for every person 65 and older.

Back to School: Why Grit(毅力) Is More Important than Good Grades?
       The back-to-school season is upon us, and once again, parents across the country have loaded their kids’ backpacks up with snack packs and school supplies. It’s a good moment to reflect on what else we should be giving our kids as they head off to school.

American parents are feeling particularly anxious about that question this year. The educational process feels more than ever like a race, one that starts in pre-preschool and doesn’t end until your child is admitted to the perfect college. Most parents are more worried than they need to be about their children’s grades, test scores and IQ. And what we don’t think about enough is how to help our children build their character—how to help them develop skills like perseverance, grit, optimism, conscientiousness, and self-control, which together do more to determine success than S.A.T. scores or I.Q.

There is growing evidence that our anxiety about our children’s school performance may actually be holding them back from learning some of these valuable skills. If you’re concerned only with a child’s G.P.A., then you will likely choose to minimize the challenges the child faces in school. With real challenge comes the risk of real failure. And in a competitive academic environment, the idea of failure can be very scary, to students and parents alike.

But experiencing failure is a critical part of building character. Recent research by a team of psychologists found that adults who had experienced little or no failure growing up were actually less happy and confident than those who had experienced a few significant setbacks in childhood. “Overcoming those obstacles,” the researchers assumed, “could teach effective coping skills, help engage social support networks, create a sense of mastery over past adversity, and foster beliefs in the ability to cope successfully in the future.”

By contrast, when we protect our children from every possible failure—when we call their teachers to get an extension on a paper; when we urge them to choose only those subjects they’re good at—we are denying them those same character-building experiences. As the psychologists Madeline Levine and Dan Kindlon have written, that can lead to difficulties in adolescence and young adulthood, when overprotected young people finally confront real problems on their own and don’t know how to overcome them.

In the classroom and outside of it, American parents need to encourage children to take chances, to challenge themselves, to risk failure. In the meantime, giving our kids room to fail may be one of the best ways we can help them succeed.
