E.g. It was while passing through Moulsey lock that Harris told me about his maze experience.
An insertion (inserted clause) appears within another clause and interrupts its structure. Their stylistic functions are rather versatile. They usually contain some information serving to make clearer what is said in the main body of the sentence, or are a casual interruption due to the speaker suddenly thinking of something vaguely connected with what he is speaking about and thus serve as a characterization of a personage’s speech manner or his state. They may serve to create two parallel speech planes, for instance, when we have reported speech.
Parallel Constructions – Parallelism is the repetition of the same syntactical structure in two or more succeeding sentences. Parallel arrangement serves to bring forth either the similarity or the difference between the objects in question. Parallelism lends a definite rhythm to the narration and due to its sameness it creates a certain background to emphasize the necessary word or phrase. This word or phrase is usually repeated in the parallel constructions. Parallelism is found in literary works where it serves as an expressive means. It is also found in scientific prose and official documents.
