in the monk's tale, we encounter seventeen stories that relate historical events. all of these stories have tragic commonalities. they tell the stories of heroes who, despite their success in life, all met sad ends. the monk blames these sad outcomes on fortune. one of fortune's traits is that she abandons people when they least expect it. this is one of the most common themes of medieval tragedies.

the present continuous is a verb tense which is mainly used to indicates that an action is in progress at the moment of speaking.  

it is formed using: person + verb to be (am/is/are) +verb + - ing form  

example: i am studying at this moment .

in addition, the present continuous is also used in order to express things that will or will not happen in the near future.

example: i am having dinner with some friends tonight.

the speaker sometimes   uses it   to express that an action is repeated and it causes irritation on the part of the speaker

example: my sister is constantly complaining about everything.
