My tutor taught me that sometimes I can reduce these sentences:
Cars
that were made in China are unsafe.
Cars
that contribute to pollution should be banned.
into these two:
Cars
made in China are unsafe.
Cars
contributing to pollution should be banned.
Also my tutor also taught me this:
Change:
The high cooking temperature alters the molecular structure of the oil,
which make the food unhealthy and difficult to digest.
into:
The high cooking temperature alters the molecular structure of the oil,
making the food unhealth and difficult to digest.
And in my recent essay, I used this method.
Instead of writing:
The success of
restaurants which convince individuals to consume relies on several techniques.
I wrote:
The success of
restaurants convincing individuals to consume relies on several techniques.
I have never figured out how these techniques work. I read some grammar books and thought the shorter sentences were related to participial phrases, but I wasn't 100 percent sure. Could you confirm the modified versions have participial phrases?
