English for Agriculture unit 6 POLYCULTURE GRAMMAR



 Relative Pronouns
Look at the following sentences:
Polyculture is an agricultural system.
In this system, two or more useful plants are grown on the same land.

Please note that:
  • We don't want to repeat 'agricultural system' and thus we substitute the relative pronoun which to combine the two sentences into one, as shown below:
Polyculture is an agricultural system in which two or more useful plants are grown on the same land.

The relative pronouns and its use:
that (used for things)
which (used for things)
who (used for people)
whom (used for people)
whose (usually used for people - shows possession)
where (used for places)

Note:
  • In speaking, 'that ' can be used for people, but not in formal, written English.

Examples:
1. where (used for places)
Look at these sentences:
Polyculture is the dominant farming systems in many areas.
In these areas, the degree of mechanization is low.

Note:
  • Because we don't want to repeat 'areas', we substitute the relative pronoun where and combine the two sentences into one sentence with 2 phrases (i.e. a compound sentence).   The sentences could be wriiten as follows:
Polyculture is the dominant farming system in many countries where the degreee of mechanization remains low.
2. that (used for things)
Look at these  sentences:
These are seeds.
I bought them yesterday.

Combining the sentences using the relative pronoun that, you might come up with the following sentence:
These are seeds that I bought them yesterday.
Please note that:
  • This is incorrect.  We don't need the pronoun them.
  • Using a relative pronoun helps us to avoid repeating a noun phrase, or using a pronoun.   In this case, using the pronoun them.
The correct sentence is
These are the seeds that I bought yesterday.
Please note that:
  • We added the before the word seed.
  • With these types of sentences we need to use the
