Sorry if some are a bit obscure - the one about Roger's eyes is to show that he is mystical/otherworldly, the Coral Island one to show Golding's satire of the book, the meeting one to show Piggy's intelligence. The rest should be fairly familiar

are best at everything"
Jack - "We've got to have rules...
and obey them. After all, we're not savages"
Jack - "Sharpen a stick...
at both ends"

understand why"
Ralph - "That was...
murder"
Ralph - "I'm frightened. Of...
us"
Piggy - "Didn't you hear what the pilot said? About the...
atom bomb?"
Piggy - "What are we? Humans?...
Or animals? Or savages?"
Piggy - "Which is better - to have rules...
and agree, or to hunt and kill?"
"arms and legs twitched a bit, like...
a pig's after it has been killed"
Piggy - "We ought to have...
a meeting"
Simon - "Maybe there is a beast...
maybe it's only us"
Simon - "As if it wasn't...
a good island"
Simon - "You'll get back...
alright. I think so, anyway"
"Simon found for them...
the fruit they could not reach
"[Simon's] eyes so bright they had deceived...
Ralph into thinking him delightfully gay and wicked"
Roger - "Let's have...
a vote"
"Fancy thinking the beast...
was something you could hunt and kill!"
"aimed, and threw it at Henry,...
threw it to miss"
"Roger's arm was conditioned...
by a civilisation that knew nothing of him and was in ruins"
"The hangman's horror...
clung to him"
"Ralph wept for the end of...
innocence, the darkness of man's heart, and the fall through the air of the true, wise friend called Piggy"
"I know. Jolly good show. Like...
the Coral Island"
"I should have thought that...
a pack of British boys [...] would have been able to put up a better show than that"
"The conch exploded into a thousand...
white fragments and ceased to exist"
"The long scar smashed
into the jungle was a bath of heat"
"ape-like...
among the tangle of trees"
"mankind's...
essential illness"
"The arrow of the sun...
fell on him [Simon]"
"The lagoon attacked them...
with a blinding effulgence [radiation]"
"This is our island. It's...
a good island"
"It [Simon's death] was an...
accident"
"What's grownups...
going to think?"
"Acting like...
a crowd of kids!"
"Piggy's head opened and...
stuff came out and turned red"
"You'll get back...
alright. I think so, anyway."
"to the endless,...
outstretched han
"Only Piggy would have the intellectual...
daring to suggest moving the fire"
"[Simon's] gaze was held by...
that ancient, inescapable recognition"
"These flies...
found Simon"
"There isn't anyone to help you...
Only me. And I'm the beast"
"The mask was a thing on its own, behind which...
Jack hid, liberated from shame and self-consciousness"
