Misplaced and Dangling Modifiers

"In High School, he rarely studied hard."

--"In High School,.." is the modifier. The modifier adds information to the noun that immediately comes after it. In this sentence, the modified noun (subject) is 'he'.

--A 'misplaced modifier' is too far away from the noun it wants to modify, and it appears to modify the wrong word.
"Burnt beyond recognition, my grandmother removed the turkey from the oven."

--the modifier 'burnt beyond recognition' wants to modify the word 'turkey'; instead, it modifies the word 'grandmother'. How would you fix the sentence?

--A 'dangling modifier' has nothing to modify, and it appears to modify the wrong word.
"After an eight hour nap, the plane landed in Taipei."

--Who took the nap? According to the sentence, the plane took the nap. You should change it to "After an eight hour nap, I awoke as the plane landed in Taipei."

Another example:
"At the age of nine, my family moved to Taichung."
--This is a dangling modifier. Change the modifier into a dependent clause.
"When I was nine, my family moved to Taichung."

Another example:
"As a family, the wife should cook and clean for her husband."
--This is another dangling modifier. It identifies only the wife "as a family." You should simply remove the modifier. (And you should make the husband cook and clean sometimes.)

Another example:
"Eating leaves from tall trees, we watched the giraffes at the zoo."
--This is a misplaced modifier because it sounds like "we" are eating leaves from tall trees. Move the prepositional phrase to the beginning of the sentence, and move the "eating..." section to after "giraffes".
"At the zoo, we watched the giraffes eating leaves from tall trees."
