值得不值得,暗含着一种计算。一个大学生跳下水救人,救起的是个拾荒老人,自己却没能上来,值得不值得?一对贫寒夫妻收养的孩子患了白血病,千呼万唤亲生父母却不愿露面,他们倾家荡产,举债坚持给孩子治病,值得不值得?类似这样的问题,都会引起诸多的讨论。焦点就在,值得不值得。性价比,如今一个热门的词儿。从购房、购物延伸到跳槽、离婚、交友,都要算一算性价比, Worth not worth it, implying a kind of calculation. A college student jumped into the water to save his life, and he was rescued by a scavenging old man, but he was not able to come up. Worth it is not worth it? A child adopted by a poor couple suffered from leukemia. His long-awaited birth parents were reluctant to show up, and they rushed to bankrupt their debts. It is worth noting that insisting on treating children is worth noting. Similar problems will cause a lot of discussion. The focus is on it, it’s worth noting. Cost-effective, now a popular word. From the purchase of homes and shopping to job-hopping, divorce, and dating, we must count the cost-effectiveness.
