Hi,
I've tried to keep your words as much as possible.
1. Whether these heroes remain famous or become notorious is dependent on what kind of things they do for their society.
2. The mass media frequently report about how political reformers who desired democratic politics and campaigned against totalitarian government at the cost of their lives. Watching this news on television, everybody esteems them as national heroes.
3.When Wang Woo Suk suggested they had faked some data for their results in stem cell research, all over the world the mass media -- television, newspapers and magazines -- harshly criticized him for deceiving people and violating scientific ethics.
4.Wang Woo Suk’s reputation as a South Korea hero resulted from the mass media's reporting that he had successfully cloned human embryos. However, he has become notorious as a liar because the mass media has now reported that his research results were faked.
5. Merger strategy has enabled Hon Hai to become the fourth largest electronics manufacturing and service company.
Best wishes, Clive
