Let us spend one day as deliberately as Nature, and not be thrown off the track by every nutshell and mosquito’s wing that falls on the rails.

the author is intending to draw attention to the plight of refugees, editorial and biography support this. both workpieces make the reader empathize with enrique as well as with the other young migrants from central america. the writer, however, is using a different approach to each text.

the editorial includes strong words to persuade readers. he is trying hard to convince readers in the us to change its refugee approach.

the biography relies on narrative techniques and figurative language which the writer uses wisely in the setting, characterization, and personification to educate readers on the topic.

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.

example: my sister is constantly complaining about everything.

but it is sometime nessary to hit key points or subjects   but is sometimes to much reveiw if there was a way to slim down the redone work it would improve for every body.
