Structure of the Progressive Forms:
subject + auxiliary verb (be) + main verb (gerund) Sometimes a modal verb can be used before the auxiliary verb: subject + modal verb (could/would/should) + auxiliary verb (be) + main verb (gerund) There are other structures such as the Present Perfect Continous: subject + auxiliary verb (have) + past participle (been) + main verb (gerund) We use the progressive from when:
- we want to describe an action that is happing right now
- we want to describe an action that will be happening in the future
- we want to describe an activity or process that started in the past and is still going on
- We are reading an interesting story right now.
- My wife is flying to Madrid tomorrow.
- My wife would be flying to Madrid tomorrow if she had a holiday.
- Our partners have been working with us for 10 years now.
