Grammar:
Present Perfect
We use the Present Perfect to say that an action happened at an unspecified time
before now. The exact time is not important.
• The action started in the PAST and is (or may be) still happening now.
You CANNOT use the Present Perfect with specific time expressions such as:
yesterday, one year ago, last week, when I was a child, when I lived in Japan, at that
moment, that day, one day, etc.
We CAN use the Present Perfect with unspecific expressions such as: ever, never,
once, many times, several times, before, so far, already, yet
Real Conditionals
Present: We use the simple present tense in the “if” clause and the result
Future: We use the simple present tense in the “if” clause and future tense in the
result
Imperative
Use the base form of the verb to express advice or commands
