In my opinion, I think you talked
about the change for a long time not just recently , so you used after heating instead of after being heated

Nice blog on IELTS.
We will use it to improve our syllabus, in our classes.

Helpful website

sir, after heating is progressive verb while after being heated is passive progressive.Both are correct.

Helo coach Simon i gain alot from your lessons and i keep following the language is simple and systematic but how can u help me evaluate my essays




The graphs show that for some 'ergative' verbs, the passive gerund is less commonly used.

After heating is a simple clause, followed by a passive sentence. It looks more natural and flowing language. While being heated is a simply passive sentence.

I think "heating" as in "after heating" is a noun referring to the process of supplying heat to the mixture. Meanwhile, in the other alternative, the passive form of the verb "heat" is used, and the subject "the mixture" is reduced as it is the same in both clauses.
By the way, I would like to express my sincere gratitute to you, Simon. Thanks to your valuable lessons, I have got an 8 in Ielts writing. I'll continue to visit your blog everyday as I've been doing for the past 5 years, so please keep sharing! Many thanks!

I'm sorry, I made a typo. I mean "gratitude".

Lucy's correct.

'heating' here is a gerund (a verb being used as a noun)
'being heated' is using the verb form

Well done Lucy. It is very rare to achieve 8 in writing and you need to eliminate 90% of your grammar and vocabulary errors to do so.

In English there are just a very few pairs of verbs with similar meanings where one must have an object and the other must not.

As the graph below shows, which is the most common depends on the meaning. For example, "After laying, the chickens ...." vs "After being laid, the [eggs] ..."



Hi everyone,
As far as I know, "After heating" implies that something happens generally and regularly. It means whenever process takes place, heating is a part of it.
But "after being treated" means it is happening presently, or as we speak, but may not happen in the future.
I hope I am right.


No, it depends on the tense of the main verb.

A) The samples conserve their cylindrical shape after being heated.

B) The samples conserved their cylindrical shape after being heated.

C) The samples have conserved their cylindrical shape after being heated.

(A) is a generalization; the others are not.

Because in this example, heating means getting hot

I think in this sentence, "heating" is a noun and it indicates the process of something being heated

i guess that "after heating"means the this process ends while "after being heated" means the exact material has been heated.

Active and passive forms of gerund have been used in these two sentences

both sentences are correct because the purpose of person speaking this is to focus on the result, not action.


Lucy and sjm gave us the right answer:

'heating' here is a gerund (a verb being used as a noun)
'being heated' is using the verb form

So, "after heating" is similar (grammatically) to "after production" (after + noun).

Hi lucy
Can you please share with us how did you study؟

well, in the phrase after heating, "heating" searves as a noun, while in the other one "heat" is used as a verb.
