     "Hey, little buddy, will you support me when I'm getting old?" Han Wenshan, 35 years old, asked his

new-born baby as he picked him up at home.

     The Chinese tradition of raising sons to support parents in their old age has been weakened by the rapidly

growing economy and improved standard of living. As is the case with developed countries, China faces an

aging society. People are living longer and having fewer children. Therefore many Chinese families are falling

into a 4-2-1 family pattern: a couple raises one child and supports four elderly parents. But few realize this

problem.

     The aging of the population is a trend that now affects a growing number of countries. Not long ago, the

Information Office of the State Council, China's cabinet, issued a white paper on measures China is taking to

help its elderly population. The paper said China's population entered the aging phase (阶段) at the end of the

20th century as the proportion of people aged 60 and above accounted for over 10 percent of the entire

population. By the end of 2005, China had nearly 144 million people over 60, accounting for 11 percent of the

population, according to the white paper.

     An expanding aged population inevitably means that many issues must be settled, as the problem concerns

every aspect of society. It puts more pressure on each family, causing disturbing economic consequences

and serious social problems. It also challenges the labor force supply and the pension system.

      "I used to think that it's not an issue for me to provide for the aged," said Han, whose parents and

parents-in-law all enjoy pensions and medical insurance. But last year Han's father suffered a serious illness

and afterward Han began to feel the pressure on his shoulders.

2. Which of the following can be used to replace the underlined word inevitably?
