You can choose one and describe it to your partners.Sample descriptions:HurricaneOne Friday, a hurricane struck the southeast of England. Between the midnight and 6:00 am the hurricane crossed the southeast corner of England with winds of up to 160 kph. It had been raining heavily for two days and the ground was very wet. Besides, it was autumn and the trees still had their leaves on. So the strong winds pushed over the trees easily. Fifteen million trees had been blown down by the strong wind. Power lines were brought down by fallen trees or branches. Electric and telephone services in some areas were cut down.SnowstormOne night there was a heavy snowstorm, and in the morning people find their gardens were covered with thick snow. Its very difficult to walk in the street. Dustman had to clean the snow with forklift. Meanwhile, the early arrival of snow caused extensive damage to the trees. With the majority of trees yet to shed their leaves, the burden of the snow proved too heavy for many, and by Friday morning, the streets were littered with broken branches.HailstormIt was rare to see such a heavy hailstorm. A heavy downpour and table tennis-ball-sized hailstones attacked our town at 7:50 pm on Wednesday. On the street some big trees fell down in the hailstorm. Mr Wang stopped his car at the roadside to take shelter from the hailstorm, but the hailstorm almost broke the windows of his car. Farmers suffered a lot. Their corns and apple trees were destroyed completely. T: Excellent description. Look at the picture again. We know the house was destroyed by a fierce cyclone. It happened in Darwin, a city in the far north of Australia. Suppose we live in Darwin. What would you feel during the cyclone and after it was over?S3: I would be frightened by the strong wind and the huge noise it would make. I would stay in bed still and wait for the end of it. After it was over, I would be astonished by the big damages it had caused and feel helpless. How weak humans are before the natural forces!Step Listening (P69)In this part, the students will listen to Christine talking about a cyclone she experienced.
