Mám dotaz. Ve vašem článku máte následující větu, kde je možné zdůraznit aktivitu:
What she does is (to) write poems.

Je možné tuto větu také otočit, jak je to u ostatních What-clauses:
To write poems is what she does.

Moc děkuji.

Ne, tuto větu nelze takhle otočit.

• To write poems is what she does.
• Writing poems is what she does.
• We're mechanics. To fix cars is what we do.
• We're mechanics. Fixing cars is what we do.

Kate comes from a family of cooks and doesn't remember ever not cooking: „Cooking is what we do and food is what we talk about.“ (dorsetecho.co­.uk) [ To cook is what we do. ]

Teaching is what we do, it is our job. (enrichproduc­t.eu) [ To teach is what we do. ]

Want to ask us a question? Answering questions is what we do – we love them (wilkinsoncou­tts.com) [ To answer questions is what we do. ]

Děkuji moc za odpověď. Když používáte gerundium, tak bych měla dotaz. U toho to zase nejde otočit takto, že: What she does is writing poems.

Děkuji

Ne, what she does is writing poems nejde.

Pomocí podmětné věty s what je možné ‘zaostřit’ i na sloveso ve větě:

She writes poems. –

• What she does is write poems.

Povšimněte si, že je zde holý infinitiv slovesa, nikoliv přítomný čas (What she does is writes) ani gerundium (What she does is writing). Použít ale můžeme i infinitiv s to (What she does is to write poems), což však není tak obvyklé. (Cleft sentences (důraz ve větě))

Another problem the screenwriter has is this: people think what he does is write dialogue. (gointothesto­ry.blcklst.com) [ what he does is writes dialogue, what he does is writing dialogue ]

Prosím Vás a tato věta s gerundiem je v pořádku?

It is writing poems that she does.

Děkuji moc.

It is writing poems that she does je gramaticky v pořádku, ale nikdo by to neřekl.

A – Where does Barbara work?

B – She doesn't work anywhere. She hasn't got a job.

A – Oh, how does she make a living then if she hasn't got a job?

B – Well, she gets a salary as the official Poet in Residence on a two-year contract at the city theatre. What she does is write poems. It is writing poems that she does.

A – That sounds like a cushy number! Nice work if you can get it!

B – I'll say! / You bet! / You can say that again! [= to teda jo !]

cushy number

Prosím Vás, je nějaké pravidlo, kdy jde použít gerundium ve What-clauses? Tato věta je z učebnice a gerundium v ní lze použít:

What made me feel guilty was seeing Patricia cry.

Následující větu jste označili za negramatickou: What she does is writing poems.

Děkuji

The two sentences may look similar, but they aren't comparable in terms of their syntax.

What I/you/he/she etc do(es) is demands the infinitive, most often the bare infinitive (i.e. without „to“.).

In the sentence What made me feel guilty was seeing Patricia cry, seeing Patricia cry is a noun phrase, and it's the subject of the verb: „seeing Patricia cry made me feel guilty.“

We're looking at a single sentence out of context. In a real context, this kind of cleft sentence is never necessary, so it's not really worth spending much time on.

• What she does is write = she writes.
• What made me feel guilty was seeing Patricia cry = seeing Patricia cry made me feel guilty.

Here's a context I've just thought up.

A: – After our argument I began to feel guilty.

B: – What made you feel guilty?

A: – Seeing Patricia cry(ing).

After our argument I began to feel guilty because I saw Patricia cry(ing).
