UNIT 4 NATURAL DISASTERS
单元核心素养
单元话题导读
When it comes to disasters,quite a lot of people believe they will come across sudden disasters in
their life. To begin with,natural disasters like earthquakes,floods and droughts occur now and then. In
addition,diseases like COVID19,cancer and tumor will attack people unexpectedly. Last but not the
least,car accidents and plane crashes cant be ignored as part of disasters.
Why are there so many disasters?The reasons may go as follows:on the one hand,some mysteries
about nature are beyond our control and understanding;on the other hand,people are careless and cant
foresee what will happen beforehand.
From what has been discussed above,we may safely draw the conclusion that disasters cant be
avoided now,but with more knowledge about nature,well certainly reduce the loss brought by them to
the smallest degree,so the prospect we are looking forward to will be both bright and encouraging.
