IELTS, TOEFL & TOEIC Vocabulary: Using 'this' in the first sentence of a new paragraph?
It is clear that following this model will be useful in increasing employee productivity....
What's wrong with the first sentence of the 2nd paragraph?
Well, the problem is the student's use of the demonstrative pronoun 'this'. In other words, 'this' is the problem when it is used to begin a new paragraph. 'This' is used to refer back to something that has been previously mentioned. Consider this sentence:
The sentence is confusing because you don't know what 'this' refers to. It's not mentioned. The sentence above is a bit like this. When we begin a new paragraph, we are 'starting again', we are beginning a new flow of thought and discussing a new and different idea from the one(s) mentioned previously. Therefore we do not recommend using 'this' to refer to a previous idea in the first sentence of a new paragraph.
So, the correct way to write the above student's work would be:
It is clear that having people doing work from home is a useful way of increasing employee productivity....
In summary: avoid using 'this' in the first sentence of a new paragraph
