Deep Structure in English divides the thought into Two Constituents: the Noun Phrase the the Verb Phrase.

The first noun "cat" in the sentence is the agent, and the first noun after the verb "mouse" is the object.

Change the order of the words and, unlike Russian, the meaning is significantly changed. "The mouse bites the cat."

This structure of English comes down right from the top (Deep Structure) and can be traced through levels of constituents (intermediate units).
Take for example the first level of constituents after the deep structure which, we will call "S." This includes a Noun Phrase (NP) and the Verb Phrase (VP).
This order is preserved right to the surface structure and is intuitively perceived by young children.
