All Together Now
- Sentences can have multiple auxiliaries before reaching the lexical verb. All auxiliaries must follow this pattern:
- Modal – Perfect – Progressive – Lexical Verb
- Tense must be carried on the leftmost verb.
- Examples:
- She has been acting strange. –> Has carries the tense, so this sentence is present tense.
- We were going there next. –> Were carries the tense, so this sentence is past tense.
- Most modals cannot carry tense. Here are examples of ones that can.
- She used to come here. –> Used to is what’s known as a generic past.
- She is going to exercise later. –> Going to is known as prospective tense.
- More examples and explanations can be found on Pg. 107 of your book.
