PRESENT: Give a group presentation to your class.
Thousands of people in Northern California were told to leave their homes in November 2018 because of spreading wildfires. Officials said the fire started as a result of lightning strikes (雷击). This is just one of the many wildfires that happened in 2018. Then how much do you know about wildfires
Wildfires are usually caused by human and natural factors (like lightning, etc.). When wildfires begin, they may threaten people and /or their personal property. So we should try to prevent them. Forest managers should be hired to protect the forest and people should be educated about prevention of forest fires.
Then what should we do when a wildfire begin We should first inform people nearby about it and evaluate them to safe places. We should try to stay calm and move to safe places as soon as possible. After the wildfire, we should provide survivors shelters to rest and medicine help for the injured.
Sample 1
On 12 May, 2008, an 8.0-magnitude earthquake happened in Wenchuan which killed over 80,000 people and left many more injured, turning many towns and counties into ruins. At the moment, numerous children lost their parents and became orphans, hundreds of families were broken, and all the people there felt helpless and frightened.
Fortunately, lots of rescue workers rushed to the area and worked around the clock, and meanwhile supplies were being sent there from all directions. With the help from all Chinese people and even abroad, some victims finally survived, and their homes have also been rebuilt. Wenchuan city has proved to China and the rest of the world that in face of disaster, people must unify and never give up.
Sample 2
It has been more than ten years since the earthquake happened, but we’ll never forget its disastrous damage and sorrow and sadness. There is no way to prevent earthquakes. But if we prepare, we can keep them from becoming disasters. If you find yourself in danger from an earthquake, first of all, remember to “drop, cover, and hold on”. Drop down onto your hands and knees, cover your head with your hands, and stay away from glass, windows, or anything that could fall. You could find cover under a desk or table. Hold on to the desk or table so it doesn’t move away from you. Second, if you are outside when quakes happen, you should go to an open space away from buildings, trees, or power lines. If you are trapped, you can use a cell phone to call or text for help. You can also tap on a pipe or a wall, or whistle for help. Then you are more likely to be found. Do get your family and friends to be familiar with the self-help knowledge.
Read the sentences about the formation and effects of tsunamis. Then match each sentence with the correct picture.
A Tectonic plates push together.
B A series of waves expands in all directions.
C Whole sections of cities are destroyed.
