require + ing

[notletrest]

"The -ing form of a verb following require always has a passive meaning." is from a dictionary..But how do you think of the one : Most tests require collecting cells . Does collecting has a passive meaning here?
Thanks!

Yes- most tests require cells to be collected (by swabbing...)

1. In my humble eyes: "The -ing form of a verb following require always has a passive meaning." means that the subject of the sentence is the acceptor of -ing ,not the object of -ing, for example, the man requires helping.= the man requires to be helped.
Am I right?
2.If the above is right, the sentence that the crops require absorbing water is wrong.
Thanks!

Like need, require is one of those verbs which may hold an objective structure: i.e.

Subj+require+object+to+infinitive

I think it is a passive in that

Most tests require cells to be collected.

The only thing here is that the agent is implied by the contests (who is meant to collect these cells? Students, biologists or just anybody???)

Most tests + require+ (people/students/biologists)+to collect cells


Therefore, in this case the object becomes the "holder"of a passive structure,

Mosts tests+require+cells+to be collected (by people/students/biologists)

which may also be rendered by adding +ing straight after require and before the object.


If you google up "Most tests require cells to be collected" you'll come across other similar sentences e.g.

Most jurisdictions require samples to be collected...

which we can change into

Most jurisdictions require collecting samples...

Hope it works for you.

According to you," I require beating the dog," is right too. Is it right?
thanks!

If anything
The dog requires beating/ The dog requires to be beaten (by who??)

That's what I meant...
Some masters require their dogs to be beaten (by their trainers) while training. (passive and objective construct)
Some masters require beating their dogs while training (passive only the agent is implied by context)

different to:

Some masters require dog trainers to beat their dogs while training (active and objective construct)

Hope it's clearer

I'm not convinced that you have a sentence in the passive voice if that's what you mean.
"Collecting" is a gerund.
"Most tests (subject) require (verb) collecting cells. (Direct object)" - Active voice sentence.
"Collecting cells is required by most tests." - Passive voice equivalent.

I am sorry but I don't think "Some masters require beating their dogs while training (passive only the agent is implied by context)" is correct,after all.
Thanks for your concern!

I enjoy your good answer to my probolem very much! Thanks to 5jj,too.
Sorry that you haven't directly pointed "Most tests require collecting cells " is wrong.
I am ashamed the sentence should appear in the Chinese graduate student for master examination topic 2009.

It isn't wrong for me.
