Something significant is happening to the world population-it is aging. The median(中位数的)age of an American in 1950    1    (be)30-today it is 41 and is expected    2    (increase)to 42 by 2050. For Japan, the    3    (number)are more striking-22 in 1950, 46 today and 53 in 2050. In 2015, one in 12 people around the world were over 65；by 2050, it will be one in six.

This aging of the population is driven    4    two factors. The first is declining birthrates, which means old generations are large    5    (compare)to younger generations, and so, on average, the population becomes    6    (old)than before. This is    7    (particular)true in the US. The second reason is that people are living longer. A child born in the US today has    8    very realistic chance of living beyond 100 and needs to plan accordingly.

People tend to focus on the first factor. However, greater attention should    9    (place)on longevity(长寿). It isn't just that people are, on average, living longer. It's also that they are on average healthier    10    more productive for longer. Therefore, they can work for longer, consume more and in general be a boost to the economy.

And nearly a fifth wanted to work as a blogger,    7    (write) content for the Internet. How does this trend come about？ It can be     8    (large) attributed to the fact that these new occupations enable young people to work for their dreams, not just for money. "These new jobs are where the biggest attractions lie： creativity, fame and the opportunity for self﹣expression," commented The Sun.

Despite the popularity     9     new occupations, experts still suggest that young people stay wise when they choose one because not everybody is     10    (suit) or has the ability for it.
