英语改错：
The impact of major construction projects on existed 1
geological features may result in unforeseen and disastrous consequences.
This is illustrated by one of the worst dam disasters in the history 2
that occurred at the Massa Dam on 1 April 1958 only two years
after the dam had been open to international acclaim as one of 3
the great engineering achievements of 20th century. Designed 4
to supply electricity for the region’s developing industrial sector and
irrigation for the farmers of the arid Lower Massa Bassin, the
massa project took seven years to complete. It took mere seven 5
minutes to collapse as an enormous landslide composed in over 6
180 million cubic metres of rock tumbled down the right bank. As the
wave poured down the valley, it swept three high-level bridges and 7
obliterated the town of Sesai, killing their 1000 inhabitants. The 8
wave was already 50 meters high when reached the Kere River 9
over two kilometers away. The Massa disaster bore a striking resemblance
to the Ryshkyk tragedy of 1949 which 500 people had been killed 10
by a wall of water which had overtopped the dam abutments.
