There comes a time when the old must give way to the new, and it is not possible to preserve everything from our

3、 past as we move towards the future. Finding and keeping the right balance between progress and the protection of cultural sites can be a big challenge.Big challenges, however, can sometimes lead to great solutions.

But the proposal led to protests.Water from the dam would likely damage a number of temples and destroy cultural relics that were an important part of Egypts cultural heritage. After listening to the scientist

5、s who had studied the problem, and citizens who lived near the dam, the government turned to the United Nations for help in 1959.A committee was established to limit damage to the Egyptian buildings and prevent the loss of cultural relics. The group asked for contributions from different departments

8、 countless cultural relics. Fifty countries donated nearly $80 million to the project.When the project ended in 1980, it was considered a great success. Not only had the countries found a path to the future that did not run over the relics of the past, but they had also learnt that it was possible f
