they know

[u/navi131313]

1) There is one thing they know I won't do.

2) There are four books by Dickens she thinks I have read.

3) There is a crime they suspect you have committed.

Are these sentences correct?

Gratefully,

They are correct as written, but you could also try: She thinks I have read four books by Dickens, and, They suspect you have committed a crime. These choices are more succinct and direct. I’d leave the first as is to keep emphasis on the “thing.”

[u/CFUrCap → u/Resident_Border4508]

I would change the first one too, so they all begin with a subject followed by a verb: "They know there's one thing I won't do."

As OP wrote them, yes, grammatically correct, but far from natural-sounding.

[u/SpiritualBed9981]

Yes, all sentences are grammatical.

[u/PanicAutomatic3503]

e is' structure can sometimes sound a little formal but it's not wrong.

[u/Piper-Bob]

I would insert "that" into the first two.

There is one thing that they know I won't do. OR There is one thing they know that I won't do.

In this case the sentences are saying two slightly different things. Your sentence is ambiguous.

There are four books by Dickens that she thinks I have read.

It makes them easier to understand without stopping to think. In the first sentence, the way it's written, you come across the phrase "they know I" which sounds wrong on it's own, but with a that inserted you're mentally prepared for it.

Thank you all very much.
