　America is growing older. Fifty - eight years ago, only 4 out of every 100 people in the United States were 65 or older. To day, 10 out of every 100 Americans are over 65. The aging of the population will affect（影响）American society in many ways—education, medicine, and business. Quietly, the graying of America has made us a very different society—one in which people have a quite different idea of what kind of behavior（行为） is suitable（合适）at various , ages.

　　A person s age no longer tells you anything about his/her social position, marriage or health. There’s no longer a particular year in which one goes to school or goes to work or gets married or starts a family. The social clock that kept us on time and told us when to go to school, get a job, or stop working isn’t as strong as it used to be. It doesn’t surprise us to hear of a 29 - year - old university president or a 35 - year -old grandmother, or a 70 year - old man who has become a father for the first time. Public ideas are changing.

　　Many people say, “I am much younger than my mother— or my father— was at my age. ”No one says“Act your age” any more. We’ve stopped looking with surprise at older people who act in youthful ways.

It can be learnt from the text that the aging of the population in America ________ .

　　A. has made people feel younger

　　B. has changed people’s social position

　　C. has changed people’s understanding of age

　　D. has slowed down the country’s social development

The underlined word “one” refers to ________ .

　　A. a society　　　　　　　　　　　B. America

　　C. a place　　　　　　　　　　　　D. population

“Act your age” means people should ________ .

　　A. be active when they are old

　　B. do the right thing at the right age

　　C. show respect for their parents young or old

　　D. take more physical exercise suitable to their age

If a 25 - year - old man becomes general manager of a big firm, the writer of the text would most probably consider it ________ .

　　A. normal　　　　　　　　　　　　B. wonderful

C. unbelievable　　　　　　　　　　D. unreasonable

Remind children that bad things don’t last. It may sound simple, but the message is extremely important. “Children often don’t have the experience to know that when something bad happens—they lose an important game or their best friends lets them down—it’s not the end of the world,” explains Nancy Leffert, a senior research scientist with the Research Institute, an American adolescents’(青少年) and children’s research group. “They think their bad feelings will last for ever， or that one failure will ruin everything.”
Unfortunately, that kind of thinking discourages motivation(动机).“If a child believes that the cause of her upset is lasting, or that nothing she does will make a difference, it decreases her ability to keep on trying,” says Dorothy Rich, president of the Mega Skills Education Center of the Home and School Institute, based in Washington. Any time you can help your child see that a situation is not lasting, that a result can be changed, or that one opinion does not reflect reality, you give her reason to hope.
Case in point: “When my daughter Kathy was eight，art was one of her favorite subjects，”says Beth，a mother of two. “Then she got an art teacher who gave a great deal of praise to one student and barely noticed the rest．Kathy was ready to give up until I explained to her，‘Never stop doing your best just because one person doesn’t give you praise.’” Beth had to repeat the advice often，and finally her daughter got the message．“Kathy is twelve now, and art is still one of her strongest subjects.”
62. According to the passage we know many children_____.
A. know how to face a failure
B. try their best to avoid a situation of failure
C. don’t want to stay in bad feelings for ever
D. tend to take a failure as the end of the world
63. Which of the following can a parent say to his children to show that one’s opinion does not reflect reality?
A. “If you call your friend and apologize，he won’t stay mad at you.”
B.　“That may be what your teacher thinks, but I see it differently.”
C.　“You have lost today, but you can try again tomorrow.”
D.　“Go ahead. Don’t care what other people think.”
64. It can be inferred from the passage that_____.
A. teachers’ praise is very important to students
B. good teachers can give students useful advice
C. teachers should not praise their students in class
D. good teachers can find each student’s favorite subject
65. The best title of the passage is_____.
A. Help Children Promote Problem Solving Ability
B. Tell Children Not to Let Failure Ruin Them
C. Set Reasonable Hopes for Your Children
D. Teach Your Children to Be Happy

Some animals apparently can resist cancer by strengthening their immune nervous system in preparation for winter，John Hopkins researchers said on Wednesday.

The scientists said their study was the first to show that the central nervous system，reacting to environmental changes，may spark changes in the body’s immune system(免疫系统) that control the growth of tumors.They said if that was the case，a better understanding of how the process works eventually could lead to new cancer treatments.

Dr.Randy Nelson，an associate professor of psychology at Hopkins，stressed at a meeting of the Society of Neuroscience that further study would be needed to confirm a connection between the length of the day，the animals’ immune system and cancer.More work also would be needed to show that the findings could be applied to human cancer.

Dr.Faye Austin，an immunologist with the National Cancer Institute in Bethesda，said，“It’s a very intriguing observation that the length of exposure to light can affect the growth of a tumor.But I think that the draws really need further work to clarify the mechanics.”

But Austin said the findings were surprising and important，only because they open up a new approach for research.

Studies showed that stress weakened the immune system in animals.They figured that because winter is stressful，the season probably causes exertion (影响) on the immune system.

The researchers reasoned that animals that compensated by boosting (促进) their immune systems as winter approached would have a better chance of surviving and producing offspring.

“In the same way that animals have evolved to select the best time to breed，it struck me that animals ought to be able to predict when conditions would be challenging immunologically.”Nelson said.
