Until late in the 20th century, most Americans spent time with people of generations. Now mid-aged Americans may not keep in touch with old people until they are old themselves. That’s because we group people by age. We put our three-year-olds together in day-care center, our 13-year-olds in school and sports activities, and our 80-year-olds in senior-citizen homes. Why?

We live away from the old for many reasons: young people sometimes avoid the old to get rid of fears for aging and dying. It is much harder to watch someone we love disappear before our eyes. Sometimes it’s so hard that we stay away from the people who need us most.

Fortunately, some of us have found our way to the old. And we have discovered that they often save the young.

A reporter moved her family onto a block filled with old people. At first her children were disappointed. But the reporter baked banana bread for the neighbors and had her children deliver it and visit them. Soon the children had many new friends, with whom they shared food, stories and projects. “My children have never been less lonely,” the reporter said.

The young, in turn, save the old. Once I was in a rest home when a visitor showed up with a baby. She was immediately surrounded. People who hadn’t gotten out of bed in a week suddenly were ringing for a wheelchair. Even those who had seemed asleep wake up to watch the child. Babies have an astonishing power to comfort and cure.

Grandparents are a special case. They give grandchildren a feeling of security and continuity. As my husband put it, “my grandparents gave me a deep sense that things would turn out right in the end.”

Grandchildren speak of attention they don’t get from worried parents. “My parents were always telling me to hurry up, and my grandparents told me to slow down,” one friend said. A teacher told me she can tell which pupils have relationships with grandparents: they are quieter, calmer, more trusting.

1.Now in an American family, people can find that ________.

A. children never live with their parents

B. not all working people live with their parents

C. aged people are supported by their grandchildren

D. grandchildren are supported by their grandparents

2.The reason why old people are left alone may be that ________.

A. the old don’t like to live in a big family

B. the young can’t get enough money to support the old

C. different generations have different lifestyles

D. the old are too weak to live with the young

3.The fact that the reporter told us shows that ________.

A. old people in America lead a hard life

B. old people in America enjoy banana bread

C. she had no time to take care of her children

D. old people are easy to get along with

4.Seeing a baby, the old people get excited because ________.

A. they had never seen a baby before

B. the baby was clever and beautiful

C. the baby brought them the image of life

D. the baby’s mother would take care of them

People born in winter are more likely to suffer mental health disorders, according to a recent study carried out by researchers at Vanderbilt University in Tennessee.

Researchers raised baby mice from birth to weaning (断奶) in either “summer” light cycles of 16 hours of light and 8 hours of dark or “winter” cycles of 8 hours of light and 16 hours of dark. A third group experienced 12 hours of light and 12 hours of dark a day.

Then half the winter mice stayed in a winter cycle, while half switched to a summer schedule. The summer mice were similarly split. The mice raised in equal periods of light and dark were split into three groups, one of which stayed on the 12?hour schedule, one of which joined the winter group, and one of which joined the summer group.

After 28 days, it turns out the summer?born mice behaved the same whether they stayed on the summer cycle or switched to winter. But among the winter?born mice, those stayed in winter kept their previous schedule, while those that switched to summer stayed active for an extra hour and a half, which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions(破坏) in their biological clocks.

The finding is the first of its kind in mammals, and it could explain why people born in winter are at higher risk for mental health disorders.

“We know that the biological clock regulates(管理) mood in humans,” said study researcher McMahon. “If the mechanism (机制) similar to the one that we found in mice operates in humans, then it could not only have an effect on a number of behavioral disorders, but also have a more general effect on personality.”

1. How many groups of mice are there finally in all in the experiment?

A.Four. B.Five. C.Six. D.Seven.

2.What's the main idea of the text?

A.The biological clock regulates mood in humans.

B.People born in winter are at higher risk for physical health disorders.

C.Being born in winter has a negative effect on people's mental health.

D.The length of light will influence the behavior of the mice.

3. The underlined word “split”(Paragraph 3) can be replaced by ________.

A.divided B.torn C.hit D.ended

4.Who is probably the reader of the passage?

A.A job?hunter.

B.A student in the university.

C.A newly?married couple.

D.An experienced dentist.

On the first day of school I brought my camera to school. I gave the students a piece of 8 ×11 cardboard(纸板), and asked them to write their names on both sides. As they finished, I asked them to get into groups of three to four students and took photographs of them holding their name cards.

After school, I developed the film and printed two sets of photos. That evening, I started to match the names with the faces. I kept one set of pictures at home for about a week so that I could review their names each night. On the second day of school, I put up the other set of photos as a bulletin board, with a title such as "Presenting Room 108, ..."

The kids loved it! After I had learned all of their names I brought the second set back to school and stuck them onto an 8 ×11 sheet of paper. I placed it in the classroom for other teachers.

The cardboard name cards that were made on the first day were collected and put on a shelf. From time to time, they were given back to the students and placed on their desks so that guests or supply teachers could identify all of the students.

I’ve been doing this with my grade 7 students for the last nine years and they liked it. It’s fun to bring the photos out again at the end of the school year to see how much they have all changed in ten months.

1.The cardboards were used to ________.

A. play some kind of game

B. decorate the classroom

C. identify the students

D. print the photos on

2.The writer of the passage might be a ________.

A. head teacher B. monitor

C. photographer D. supply teacher

3.Why did the writer leave the second set of the photos at home?

A. To memorize the students’ names at home.

B. To make cardboard name cards for supply teachers.

C. To make a bulletin board in the classroom.

D. To match the students’ names with their faces

4.Which of the following is TRUE according to the passage?

A. The students didn’t have to use the cardboard name cards to identify each other.

B. Other teachers couldn’t identify the students without the cardboard name cards.

C. The writer kept the cardboard name cards as a souvenir for nine years.

D. The guests will know the students’ names by reading the cardboard name cards.

Conventional wisdom says that hardship can make us old before our time. In fact, a new study suggests that violence not only leaves long-term scars on children’s bodies, but also changes their DNA, causing changes that are equal to seven to ten years of premature aging.

Scientists measured this by studying the ends of children’s chromosomes(染色体), called telomeres, says Idan Shalev, lead author of a study published in Molecular Psychiatry.

Telomeres are special DNA sequences which prevent the DNA in chromosomes from separating. They get shorter each time a cell divides, until a cell cannot divide any more and dies.

Several factors have been found to shorten telomeres, including smoking, radiation and psychological stresses such as being treated badly when young and taking care of a chronically ill person.

In this study, researchers examined whether exposure to violence could make children’s telomeres shorten faster than normal. They interviewed the mothers of 236 children at ages 5, 7 and 10, asking whether the youngsters had been exposed to domestic violence between the mother and her partner; physical maltreatment by an adult; or bullying. Researchers measured the children’s telomeres—in cells obtained by swabbing the insides of their cheeks—at ages 5 and 10.

Telomeres shortened faster in kids exposed to two or more types of violence, says Shalev. Unless that pattern changes, the study suggests, these kids could be expected to develop diseases of aging, such as heart attacks or memory loss, seven to 10 years earlier than their peers.

Shalev says there is hope for these kids. His study found that, in rare cases, telomeres can lengthen. Better nutrition, exercise and stress reduction are three things that may be able to lengthen telomeres, he says.

He study confirms a small but growing number of studies suggesting that early childhood adversity imprints itself in our chromosomes, says Charles Nelson, a professor of pediatrics and neuroscience at Harvard Medical School.
