其实我觉得old people in china are generally unhappy呢,不过还是为你找了几个论据:
frist ,with the advanced technology in modern times,old people are able to lead a convenient life,because they have what they want ,such as tv ,computer, old people could also,as long as they are willing to , chat and surf on the internet as anybody else,and this definitely makes them feel happy.
second,the couples nowadays do not have enough time to raise the child,and old people in china just get this chance to bring up their grandson or granddaught then,this can also bring a lot of joy to their boring life everyday.
我尽力啦!想出两个,请绝对放心,完全没有语法问题的,是我自己写的,不是工具翻译的。
