Although penguins look clumsy on land. They are graceful in the water. Their bodies are perfectly suited for swimming and diving. They are a streamlined torpedo shape. Their wings are shaped like flippers penguins use them to propel themselves through the water at speeds up to 30 miles per hour. Use their webbed feet to steer. Most penguins can even swim like porpoises. Leaping out of the water to breathe and then diving back in with one graceful motion. Penguins frequently need to dive deep to catch prey. Sometimes descending to depths of over a thousand feet. The water pressure can be great enough to collapse lungs. Penguins special air chambers in their bodies. When a penguin dives, the chambers squeeze, air is forced into the lungs. The extra air keeps the lungs from collapsing. The chilly waters that penguins prefer would be too cold for most birds, penguins are insulated by waterproof feathers and a thick layer of fat. Penguins more than make up for being awkward on land. By being perfectly suited for the water.

Explanation:

The corrections needed in the given passage are as follows-

1. The use of a comma after land- this allows the two sentences to join together and flow into one sentence. It gives much more free flow of words in the sentence.

2. Semi-colon after flippers- this provides connectivity for the two independent clauses which have the same thought.

3. Use of "and" after hour connects the two sentences and merged them into a single sentence.

4. A comma after "porpoises" allows the sentence to continue without the need for a new sentence. It also provides an extra detail for the meaning of the statement.

5. use of a comma after "prey' provides another detail in the sentence.

6. The use of "but' after lungs provides contrasting ides to the previous sentence.

7. Addition of "and" after squeeze to connect and provide a smooth flow of words.

8. But" after most birds which presents a contrasting idea.

9. Joining the last two sentences allows the whole passage to be perfectly concluded.

explanation:

the intellectual community is a place like a university where people with high marks, or original thought or an outstanding interest in something gather. they take classes together. they discuss things. they argue sometimes, and not always in a friendly way. but if they argue, it is because they are passionate about something, and there is nothing the matter with that.

lately i've been hearing rumors that it is not the way it was when i went to school. the one thing all schools used to have was free speech. the 1st amendment rights were sacred. now i'm hearing they are not. students can be reported and disciplined for giving an off the wall opinion.

that is shameful.

intellectual ideas are meant to be discussed. they are meant to be chewed up and worked on. that is the primary responsibility of every intellectual community. if that is not the way it is, then that is not a school to go to.

social media, in my opinion, and this is just an opinion. i wouldn't take it too seriously, complicates everything to do with human communication. you can want to share things and others feel they have the right to be very critical or sarcastic or mean about what you share. lack of respect is an immeasurable intolerable condition and social media abounds with that sort of thing.

one of the things i really like about is how careful people are because they must have some idea that the mods are exactly what the word says they are. they police this board very well, and what is so remarkable about them is that they are no older than the average grade 12 student.

my hat goes off to them (which means i respect them quite a bit).
