Key word transformations

New expression:
-to place the blame on: to say it is sb/sth's fault if sth has happend
                                  "Joe has placed the blame for the accident on Sarah".


While I had some problems at choosing the right order of words in the sentence e.g.:
-Do you have any objection to me coming over to see you later?
-When you have made up your mind what you want to do please let us know.
