MORE POINTS (if two people answer) What steps do you follow while actively reading to identify the main theme of a reading or listening selection?

first of all read the whole passage properly ,

identify what sentence or more used words are

try to connect with the each sentence by learning its meaning

have a watch at the last three four lines and try your best to clearly understand them

look if you need really bad i will you

specific audience will understand the main ideas. for example, if you were writing an instruction manual for rocket scientists, it would likely look very different from one you would write for young children. your language, tone, and writing style would change significantly.
