Samuel Preston, a sociologist at the University of Pennsylvania, studied how the American family is changing. He reported that by the time the average American couple reaches about 40 years of age, their parents are usually still alive. The statistics show the change in lifestyles and responsibilities of aging (老龄化) Americans. The average middle-aged couple can look forward to caring for elderly parents sometime after their own children have grown up. Moreover, because people today live longer after an illness than people did years ago, family members must provide long-term care. These facts also mean that after caregivers provide for their elderly parents, who will eventually die, they will be old and may require care too. When they do, their spouses (配偶) will probably take care of them because they have had fewer children than their parents did.
Because Americans are living longer than ever, more social workers have begun to study ways of caregiving to improve the care of the elderly. They have found that all caregivers share a common characteristic; They believe that they are the best people for the job. The social workers have also discovered three basic reasons why the caregivers take on the responsibility of caring for an elderly, dependent relative. Many caregivers believe they had an obligation (职责) to help their relatives. Some think that helping others makes them feel more useful. Others hope that by helping someone now, they will deserve care when they become old and dependent.
Samuel Preston's study shows that______.
A．lifestyles and responsibilities of the elderly are not changing
B．most American couples over 40 have no living parents
C．middle-aged Americans have to take care of their children and parents at the same time
D．elderly people may need care for a long time because they live longer after an illness
experimenting on mice. They are studying the relationship between diet and health. At this time, over one hundred experiments are being done in this laboratory.
In one of these experiments, the scientists are studying the relationship between the amount of food the mice eat and their health. The mice are in three groups. All three groups are receiving the same healthy diet. But the amount of food that each group is receiving is different. The first group is eating one cup of food each day, the second group is eating two cups, and the third group of mice is eating three cups.
After three years, the healthiest group is the one that is only eating one cup of food each day. The mice in this group are thinner than normal mice. But they are more active. Most of the day, they are running, playing with one another, and using the equipment in their cages. Also, they are living longer. Mice usually live for two years. Most of the mice in this group are still alive after three years.
The second group of mice is normal weight. They are healthy, too. They are active, but not as active as the thinner mice. But they are only living about two years, not the three years or more of the thinner mice.
The last group of mice is receiving more food than the other two groups. Most of the day, these mice are eating or sleeping. They are not very active. These mice are living longer than the scientists thought - about a year and a half. But they aren't as healthy. They're sick more often than the other two groups.

What explains these large differences in living standards among countries and over time？ The answer is surprisingly simple. Almost all variation in living standards is attributable to differences in countries' productivity—hat is, the amount of goods and services produced from each hour of a worker's time. In nations where workers can produce a large quantity of goods and services per unit of time, most people enjoy a high standard of living; in nations where workers are less productive, most people must endure a more meager existence. Similarly, the growth rate of a nation's productivity determines the growth rate of its average income.
The fundamental relationship between productivity and living standards is simple, but its implications are far-reaching. If productivity is the primary determinant of living standards, other explanations must be of secondary importance. For example, people might think that labor unions or minimum-wage laws contributed to the rise in living standards of American workers over the past century. Yet the real hero of American workers is their rising productivity.
The relationship between productivity and living standards also has great implications for public policy. When thinking about how any policy will affect living standards, the key question is how it will affect our ability to produce goods and services. To improve living standards, policymakers need to raise productivity by ensuring that workers are well educated, have the tools needed to produce goods and services, and have access to the best available technology.

Survey results indicate that smoking and alcohol and marijuana(大麻) use increased among residents of Manhattan during the 5～8 weeks after the terrorist attacks on the World Trade Center which took place on September 11, 2001. Almost one third of the nearly 1,000 persons interviewed reported an increased use of alcohol, marijuana, or cigarettes following the September 11th attacks. The largest increase was in alcohol use. 1About one fourth of the respondents said they were drinking more alcohol in the weeks after September 11; about 10% reported an increase in smoking, and 3.2% said they had increased their use of marijuana.
The investigators found survey participants by randomly dialing New York City phone numbers and screened (筛选) potential respondents for Manhattan residents living in areas close to the World Trade Center. Interviews were conducted with 988 individuals between October 16 and November 15, 2001. Participants were asked about their cigarette smoking, alcohol drinking, and marijuana use habits before and after September 11. During the week prior to September 11, 2001, 22.6% of the participants reported smoking cigarettes, 59.1% drinking alcohol, and 4.4% using marijuana. After September 11th, 23.4% reported smoking cigarettes, 64.4% drinking alcohol, and 5.7% smoking marijuana. Among those who smoked, almost 10% reported smoking at least an extra pack of cigarettes a week and among those who drank alcohol, more than 20% reported drinking at least one extra drink a day.
The researchers found that people who reported an increase in substance abuse were more likely to suffer from post traumatic(外伤的)stress disorder (PTSD) and from depression. People who reported an increase in cigarette smoking or marijuana use were also more likely to have both P1SD and depression, while those who reported an increase in alcohol use were more likely to have depression only. Persons who were living closer to the World Trade Center were more likely to increase their cigarette smoking, but other factors such as being displaced from home, losing possessions during the attacks, or being involved in the rescue efforts were not consistently associated with increased substance use. Symptoms of panic attack were associated with an increase in the use of all substances.
Increase in substance abuse did not differ significantly between men and women or among racial or ethnic groups. Demographic(人口统计学的) factors such ms age, marital status, and income seemed to play a more critical role in determining if the events of September 11th led to an increase in substance use.
The survey results suggest that the largest increase in substance use was ______.
A．alcohol
B．marijuana
C．cigarettes
D．cocaine

Night of the Living Ants
When an ant dies，other ants move the dead insect out of the nest．This behavior. is interesting to scientists，who wonder how ants know for sure-and so soon-that another ant is dead．
Dong-Hwan Choe，a scientist at the University of California，found that Argentine ants have a chemical on the outside of their bodies that signals to other ants，“I’m dead-take me away．”
But there's a twist to Choe's discovery．Choe says that the living ants-not just the dead ones -have this death chemical．In other words，while an ant crawls around，perhaps in a picnic or home，it's telling other ants that it's dead．
What keeps ants from hauling away the living dead？Choe found that Argentine ants have two additional chemicals on their bodies，and these tell nearby ants something like，“Wait-I'm not dead yet．” So Choe's research turned up two sets of chemical signals in ants：one says，“I'm dead，”the other set says，“I'm not dead yet．”
Other scientists have tried to figure out how ants know when another ant is dead．If an ant is knocked unconscious，other ants leave it alone until it wakes up．That means ants know that unmoving ants can still be alive．
Choe suspects that when an Argentine ant dies．the chemical that says“Wait-I'm not dead yet” quickly goes away．Once that chemical is gone，only the one that says“I'm dead”is left．“It's because the dead ant no longer smells like a living ant that it gets carried to the graveyard(墓地)，not because its body releases new，unique chemicals after death，”said Choe．When other ants detect the“dead”chemical without the“not dead yet”chemical，they haul away the body．This was Choe's hypothesis(假设)．
To test his hypothesis，Choe and his team put different chemicals on Argentine ant pupae(蛹)． When the scientists used the“I'm dead”chemical，other ants quickly hauled the treated pupae away． When the scientists used the“Wait-I'm not dead yet”chemical，other ants left the treated pupae alone． Choe believes this behavior. shows that the“not dead yet”chemical overrides(优胜于)the“dead”chemical when picked up by adult ants．And that when an ant dies，the“not dead yet”chemical fades away． Other nearby ants then detect the remaining“dead”chemical and remove the body from the nest．
The phrase“this death chemical”in paragraph 3 refers to
A．the chemical that contains poison．
B．the chemical that announces death．
C．the chemical that prevents death．
D．the chemical that causes death．
