Adverbial phrases at the beginning of a simple sentence normally form a separate intonation group pronounced with the Low Rise or the Mid Level, eg:
> Yesterday | I "* stayed ^ in all day.
On the , side-board | the VBrowns 'usually have a 'bowl of x fruit.
In sentence final position the adverbial phrases do not form an intonation group, eg:
I ~* stayed ã in all .day yesterday.
The V Browns 'usually have a 'bowl of vfruit on the .side board.
But if the adverbial phrase in the sentence final position qualifies the meaning of the sentence, rather in a manner of an afterthought, added comments, restrictions or clarifications, it is pronounced as a separate intonation group, eg:
Any news of Mary? — She is "* coming to ,Moscow | to-day. What shall I do with it? — Send it atway | at ,once.
So as we see here in the reply to the first question the speaker wants primarily to say that Mary is coming to Moscow, the
second part of the reply giving additional comments to the phrase.
