Sound Like a Native

Collocations are two or more words that usually go together and sound more natural to native speakers.  For instance, instead of saying “have a break” native speakers would say “take a break.”  Instead of saying “make a crime” native speakers would say “commit a crime.”  Instead of saying “wash the dishes” native speakers would say “do the dishes.”  It’s not necessarily that the other sentences are wrong, it’s just not how native English speakers talk.

Using Reflexive Pronouns

Reflexive pronouns (myself, yourself, ourselves) are used when the subject and object are the same and when you want to emphasize the subject.  For instance, instead of saying “I hurt me,” you would use the reflexive and say “I hurt myself” because the subject and object are the same.  In order to give extra emphasis to who is doing what, you might say “I’ll do it myself” rather than just saying “I’ll do it” because you want to point out that you are the one doing it all by yourself.
