A
Read the article about a natural disaster in Canada. Then answer the questions below. (P 61)
1. Why was the storm in 1998 unusual in Canada
Because it was not ordinary rain—it turned to ice as it fell through the cold air. It rained for six days and as much as ten centimentres of ice collected on roads, trees and power lines.
Check your answer
2. What problems did the storm cause
It caused many power lines to fall down
and many people had no electricity. It
also made the roads dangerous to walk
or drive on. In addition, many homes
were damaged and many people lost
their business.
3. Did the trouble end when the ice
storm stopped Why or why not
No. Because the huge amount of
ice made the whole area very
dangerous. As the ice started to melt,
it fell from the roofs of buildings and
trees like knives. Most of the power
lines were so badly damaged that
they could not be repaired.
Fill in the table below and make a brief report about the ice storm.
