3. What d yu knw abut the signs f a natural disaster?
Nature is kind f a lving mther, but als a butcher in cld bld. — Victr Hug
As a lving mther, nature nurtures all living things n Earth. It prvides fresh air, clean water and fertile land fr humans, animals and plants t thrive. The gentle breeze, the blming flwers and the lush frests all shw nature’s warm and caring side.Hwever, nature can turn int a ruthless butcher in an instant. When an earthquake strikes, the grund shakes vilently, and buildings cllapse in secnds. Tsunamis triggered by underwater quakes can sweep away entire castal villages. Hurricanes and typhns bring destructive winds and heavy rains, leaving nthing but ruins in their path. Even drughts and wildfires can turn green lands int deserts and ashes, threatening the lives f cuntless creatures.We cannt change nature’s dual nature, but we can learn t respect and understand it. By mastering the knwledge f natural disasters and taking prper preventive measures, we can reduce the harm caused by nature’s cruel side and better enjy the gifts frm ur lving mther nature.
