200 English Grammar Mistakes!: A workbook of Common Grammar and Punctuation Errors with Examples, Exercises and Solutions So You Never Make Them Again

Active Voice versus Passive Voices
In an active voice, the subject acts upon the verb. However, in a passive
voice, the subject receives the action of the verb. When the passive voice is
used properly, it is correct. However, when it is not used in moderation, it
becomes weak and incorrect.
Examples of Active Voice:
Monkeys love bananas.
The dog tossed the bone away.
Examples of Passive Voice:
Bananas are loved by monkeys.
The bone was tossed away by the dog.

Except versus Accept
Students are often guilty of using “accept” when “except” would be more
appropriate and vice versa. “Accept” means to receive something offered or
agree with something or someone. On the other hand, “except” means
excluding something or someone. Hence, the two words are not synonymous.
Here are some common wrong usages of these words and the appropriate
way to use them:
Incorrect: 
My mother can tolerate any other behavior from me
