Just a quick word on like versus as. A lot of people use that explanation "actions" versus "nouns". I don't like it. And the reason I don't like it is that a lot of actions ARE nouns. For example:
Like swimming, jogging is good the for blood.
We don't need "as" there, even though both swimming and jogging are nouns.
The correct explanation of the difference between the two is that like compares NOUNS, and as compares CLAUSES (a group of words containing a verb IN A TENSE).
EXAMPLES. Decide if you like or don't like these 4 on your own, then check the key at the end.
1. Just like swimming is good exercise, so is jazzercise.
2. Even though Dave, like my brother, is crazy, I still like him.
3. Monopoly is quickly becoming a very popular game, just like The Game of Life once did.
4. Like a man running for his life in the wilderness, the panther is nearly extinct.
1. The first set of words has a verb in it here, which means it must be a clause. This means that it is not correct as written. We need "as".
2. "Like my brother" has no verb in it, which means we are simply comparing nouns, and the sentence is correct as written.
3. The words after the comma do contain a verb ("did"), meaning this is a clause, so we should have "as", not "like".
4. "Running" is not actually a verb, it's a participle. There is no verb in the first phrase here, meaning it is not a clause, so the "like" is correct.
Hope that helps!
