7.Unit4自然灾害 第一段（朗读+讲解）

Today, natural disasters, such as floods, droughts, landslides, typhoons, hurricanes, tornadoes and tsunamis, often strike towns and villages, causing human deaths or great damage to people’s property. The most dangerous of them is the volcanic eruption. An active volcano can erupt at any time. Its great power can ruin crops, destroy houses and even bury villages. When a tsunami comes, the waves can crash buildings and sweep away crops. Experts say people should remain calm in the face of an emergency. Experts also give a summary of the effect of some natural disasters. Although they affect people’s lives, the effect is not as serious as people imagine.
如今，自然灾害，如洪水，干旱，山体滑坡，台风，飓风，龙卷风和海啸，时常袭击城镇和村庄，造成人员死亡或巨额财产损失。其中最危险的是火山爆发。活火山随时都可能爆发。它的强大威力可以毁掉庄稼，摧毁房屋，甚至埋没村庄。海啸来的时候，海浪会冲毁建筑物，冲走庄稼。专家说人们在紧急情况下要保持冷静，他们还对自然灾害的影响做了总结。虽然它们影响了人们的生活，但其影响并不像人们想象的那么严重。
