       The worst US economic depression in the recent 70 years is forcing senior citizens out of retirement, leaving them fighting for jobs in a weak labor market or risking homelessness.

       The study by Experience Works, released on Tuesday, showed 46 percent of the 2,000 low income people over 55 years who participated needed to find work to keep their homes. Nearly half of them had been searching for work for more than a year.

      “These people are at the age where they understandably thought their job-searching years were behind them,” said Cynthia Metzler, president and CEO of Experience Works.

       “Bur here they are, many in their 60s, 70s and beyond, desperate to find work so they can keep a roof over their heads and food on the table.”

       According to the study, many of the participants had no intention of working past their 60 th birthday, but _______ after being laid off or following the death of the partner. Over a third of the participants had retired.

       Ninety percent of the respondents 76 years and older planned to continue working for the next five years.

       Huge medical bills due to a persona illness or that of a partner were also reasons for coming out of retirement, the survey found. The longest and deepest economic decline since the 1930s is making finding a job for the low-income elderly workers a difficult challenge.

       The Experience Works study found that 46 percent of the elderly jobseekers were sometimes forced to choose between paying rent and buying food or medication. Almost three-quarters believed their age made it harder to compete for jobs with younger workers.

       “This study underscores calls for the need to create policies that remove barriers to employment for elder workers and provide additional programs and services specifically aimed at helping elder people re-enter the work force or remain working,” said Metzler.

The Coalition for the Homeless is an organization that seeks to address the needs of the homeless population in the United States. It is a network of offices, some of which provide food and houses for the homeless population, and some of which fight for the passing of laws that would give every American the right to a place to call home. According to the Coalition’s studies, of over two hundred million people living in th U?ited States, up to three million are homeless—and the number is still growing. Since the late 1970s, fast-rising house prices, large cuts in government supported housing programs, and economic recession(經(jīng)濟(jì)衰退) have made it impossible for many Americans to meet housing costs. Sadly, this has resulted in a number of persons being forced to leave their homes and/or unable to find new affordable homes.According to another research, families with children appear to be the fastest-growing part of the homeless population, making up 39% of it. The old idea of a homeless person, that of the single man who gets drunk all the time, is no longer true. A much larger part of the population now finds itself homeless. Even worse, once a person becomes homeless, he often finds it impossible to find a job, since most employers require anyone who wants a job from them to provide a home address on a job application.

1. The word “address” in the first line probably means 　　　　 .

A. talk about　　　 B. deal with　　　 C. fight for　　　 D. write to

2. How many people are homeless in the U.S. according to the Coalition studies?

A. 39% of the population.　　　　　　　　 B. 200 million people.

C. About 3 million people.　　　　　　　　 D. About one-fifth of the population.

3. Homeless people often have difficulty finding a job because________.

A. they have no home addresses

B. they mostly have a drinking problem

C. they aren't supported by government programs

D. they often don't have enough work experience

4. What is the main cause of the rising number of the homeless in the U.S.?

A. The passing of new housing laws.

C. The slow construction of houses.

D. The ever-rising price of housing.
