Adverb Sentence Placement
Adverbs of Manner: Adverbs of manner are placed after the verb or entire expression (at the end of the sentence).For example: Their teacher speaks quickly.
Adverbs of Time: Adverbs of time are placed after the verb or entire expression (at the end of the sentence).
For example: She visited her friends last year.

For example: He often goes to bed late. Do you sometimes get up early?

Important Exceptions to Adverb Placement
Some adverbs are placed at the beginning of a sentence to provide more emphasis.For example: Now you tell me you can't come!
Adverbs of frequency are placed after the verb 'to be' when used as the main verb of the sentence.
For example: Jack is often late for work.
Some adverbs of frequency (sometimes, usually, normally) are also placed at the beginning of the sentence for emphasis.
For example: Sometimes I visit my friends in London.
