Horrible Incident

This week is an unstable week. At first it rained heavily like a huge typhoon struck in Taiwan. Then a strong earthquake waked me up at the morning. At the same day, a horrible incident happened in MRT. A teenager just as my ages took two knives and killed four people randomly. Moreover more than 20 people injured and cause tens of thousands of people afraid of taking metro. To people's surprise, his reason of his terrifying behavior is that he want to do something great. Nowadays many topics were discussed such as what is the problem let a high educated student to commit such a nonsense action? In my opinion, government should pay more attention to the security of public transportation system. Besides,teachers and parents should take more care of their students and children to stop they from imitating his behavior. I hope everything goes well in the future, and won't cause too many fear in life.
