Their complexions too, differing so much from ours, their long hair and the language they spoke (which was very different from any i had ever heard) united to confirm in me this belief. indeed such were the horrors of my views and fears at the moment that, if ten thousand worlds had been my own, i would have freely parted with them all to have exchanged my condition with that of the meanest slave in my own country. when i looked round the ship too and saw a large furnace or copper boiling and a multitude of black people of every description chained together, every one of their countenances expressing dejection and sorrow, i no longer doubted of my fate; and quite overpowered with horror and anguish, i fell motionless on the deck and fainted. paraphrase the central idea. paraphrase the supporting details.

This is an account by Olaudah Equiano, an Igbo abolitionist and writer who was enslaved as a child.

In this section, Equiano remembers how he felt when he arrived as a slave to the boat that was going to transport him. The central idea is that upon getting on the boat, seeing how different the captors looked and how the black people were chained, he realized what his fate was. This made him deeply scared and miserable and caused him to faint on the deck.

animal farm, written by george orwell, is a representation of russia after the revolution that led stalin to take over power.

in this excerpt, the central idea seems to be that the animals (a representation of society), when they believe to be working for a greater good and equality, are obedient and productive. they were convinced that, after expelling the owner (jones) from the farm, they would live in harmony and be fairly treated.

as we know, the pigs become the leaders and grow more selfish and dictatorial with time. in the end, they look and act in a way so similar to humans that it is impossible to tell the difference. the ideals of equality are shattered, and the farm turns out to be worse than it was before. the animals are manipulated with false propaganda and forced to work in order to enrich the pigs.

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.
