Please give me a hand to figure out this problem !!!
This sentence from my homework finding the mistakes in the sentence.
Some methods to prevent soil erosion are plowing parallel with the slopes of hills to plant trees on unproductive land, and rotating crops.
- "to prevent soil erosion" is an adjective phrase modifying the noun "methods"
- "to plant trees" is the mistake in this sentence. I have changed it to "planting"
My question is what the role of "TO" in "to prevent soil erosion" is.
There is another example, "Can you tell me the way to solve this problem?"
So what is "TO"?
Is it the Preposition? I have learned that after Preposition, we usually have a Noun, a Pronoun or a Gerund. Is it the reason why "TO" is an exception because we just use TO before the Verb Bare Infinitive?
Is there any difference between
Some methods OF preventing soil erosion...
Some methods TO prevent soil erosion ...
Thanks for your attention.
