A Sad News

A news report said that an old man dead died (dead 是形容词，died 是过去时态的动词) at home, and his son didn’t know that until several days later, ago, because he worked in another city. was not at home,he worked in another place. It is a very sad news.
I think there are many similar problems in China. In the past, more than 70 percent of people lived in the countryside. Since the 1990s, China’s economic economy (economic 是形容词, economy 是名词) has been developing rapidly. Many adults leaved left their villages and went to cities for a good better future. Only old parents and young kids stayed at home.
Adults worked in cities, and most of them came back home once a year, or even once every several years one time. They can’t meet see their parents and kids everyday, and they also can’t talk with their parents and kids everyday by phone or computer. So sometimes they don’t know what happens in the distant hometown.
There are many other problems. For example, many kids treat their parents like strangers because they haven't seen them in such a long time.
