Complex sentences contain the principal clause and one or more subordinate clauses. The latter may follow the principal clause, precede it or break the main clause into two parts. If an adverbial clause precedes the principal one and makes a separate intonation-group, it is usually pronounced with the Low Rise as it implies continuation. For example:↓When it 'gets ˏdark, | ↓Moscow 'looks es'pecially ˎbeautiful. In case the complex sentence begins with the principal clause and contains more than one intonation-group both the clauses are usually pronounced with the low-falling nuclear tone. For example: →Go to the ˎcountry | if you ↓want to 'have a ˎrest.
