Future Perfect Vs. Future Perfect Progressive

How long can one verb be?

When a verb is comprised of four parts, it starts to get complicated—and that’s exactly what happens with the future perfect progressive (will + have + been + -ing verb). The future perfect and the future perfect progressive are rarely used in English, so should we bother teaching these tenses to our students? My view is that if students will come across it, we need to teach it to them at some point (but you can definitely wait until they’re at an advanced level). Just be sure to mention that since it’s unusual to know for sure what will happen at two points in the future, these tenses are rarely used. Also, they are quite formal, and we usually substitute the simple future and the future progressive for a more informal style. But for advanced students and those taking a test like the TOEIC, TOEFL, IELTS, etc., here’s a tried-and-true method for making the future perfect and future perfect progressive as clear as possible.

Future Perfect: WILL + HAVE + P.P.

The future perfect is formed with the future modal will, the base verb have, and the past participle of the main verb. It is used when you think the first future action will finish before the second future action. The following diagram will help illustrate this to your students:

Make sure you point out that a simple present verb is used in the dependent clause, so students need to be careful of the subject (the verb will end in -s for the following subjects: she, he, it, a singular count/countable noun, and a non-count/uncountable noun).

Future Perfect Progressive: WILL + HAVE + BEEN + -ING VERB

The future perfect progressive is formed with the future modal will, the base verb have, the past participle been, and the -ing form of the main verb. It is used when you think the first future action will continue until the second future action. The following diagram will help illustrate this to your students:

Again, a simple present verb is used in the dependent clause, so students need to determine if the subject requires an -s ending.

Note: If you want to elaborate for more advanced students, you can explain that the future perfect progressive is formed by combining the future perfect (will + have + p.p.) plus the basic progressive pattern (be + -ing verb). Since the past participle of the Be verb is been, you get will + have + been + -ing verb. Also note that have will never be has (no matter what the subject is) because it is always modal + base verb.

Comparison Chart

To compare the two verb tenses and show your sudents examples, use the following verb chart. You can print out the chart and make photocopies, show them on the computer, or write it out on the board.

Important Note

When giving your students examples, it is very important to mix up the order of the independent and dependent clauses. Make sure that you give some examples where the independent clause comes first (with the future perfect or future perfect progressive tense), and others where the dependent clause comes first (with the simple present tense). Point out that when the dependent clause comes first, students must use a comma between the clauses. Showing both types of examples means that students won’t simple memorize “will + have + been + p.p. first, present verb second”, which can cause errors.

    You’ve broken it down really well! I am wondering if you would mind doing a post on gerunds vs participles and their usage in respective clauses. Thanks

    The chart you’ve shared is really great!
    Will you be kind enough to share some explanations on “perfect form of infinitives”?
