As a online learner, online learning is more convenience and more comfortable for me. Because i don't need to take one and a half hours back to school, also i can have lesson where i feel comfortable to study.

 Online learning save the time of transportation. As a pianist, i can use this time to practice more to improve my skills.
3. What disadvantages do you experience under this new human behaviour?
 During the lesson, there are many things to distracted me at home such as bed, TV, phone. Less fact-to -fact interaction not only make me lost focus in class but also reduced my knowledge absorption.

Which disaster is the most profound?
I think Man-made disaster is the most threatening and serious. Since disaster like, typhoon, earthquake is part of the natural even if a natural disasters occurs, mankind is inevitable. But most man-made disasters are caused by people's selfishness and hatred, it cause many innocent people to die and leave trauma. Exhaust gas and sewage from factories will cause the death of other organisms on the planet. In my opinion, If people have different opinions and conflicts of interest, they should not kill each other. because every life on earth is so precious and life is priceless. If people don't fight against each others, our world we be more lovely and peaceful<3
