The news that Dr. Blare had refused to join the Antarctic expedition was sensational. We are not prepared to discuss the question who will chair the next session of the Surgical Society.
The nominal appositive clauses can be tested by transforming them into the corresponding clauses of primary nominal positions through the omission of the noun-antecedent or translating it into a predicative complement. Cf.:
... → That Dr. Blare had refused to join the Antarctic expedition was sensational. —» That Dr. Blare had refused to join the Antarctic expedition was sensational news.
The characteristic antecedents of adverbial apposition are abstract names of adverbial relations, such as time, moment, place, condition, purpose, etc. Cf.:
We saw him at the moment he was opening the door of his Cadillac. They did it with the purpose that no one else might share the responsibility for the outcome of the venture.

As is seen from the examples, these appositive clauses serve a mixed or double function, i. e. a function constituting a mixture of nominal and adverbial properties. They may be tested by transforming them into the corresponding adverbial clauses through the omission of the noun-antecedent and, if necessary, the introduction of conjunctive adverbialisers. Cf.:
... → We saw him as he was opening the door of his Cadillac. ... → They did it so that no one else might share the responsibility for the outcome of the venture.
Appositive clauses of pronominal relation refer to an antecedent expressed by an indefinite or demonstrative pronoun. The constructions serve as informatively limiting and attention-focusing means in contrast to the parallel non-appositive constructions. Cf.:
I couldn't agree with all that she was saying in her irritation. → I couldn't agree with what she was saying in her irritation. (Limitation is expressed.) That which did strike us was the inspector's utter ignorance of the details of the case. → What did strike us was the inspector's utter ignorance of the details of the case. (The utterances are practically equivalent, the one with a clausal apposition being somewhat more intense in its delimitation of the desired focus of attention.)
Appositive clauses of anticipatory relation are used in constructions with the anticipatory pronoun (namely, the anticipatory it, occasionally the demonstratives this, that). There are two varieties of these constructions — subjective and objective. The subjective clausal apposition is by far the basic one, both in terms of occurrence (it affects all the notional verbs of the vocabulary, not only transitive) and functional range (it possesses a universal sentence-transforming force). Thus, the objective anticipatory apposition is always interchangeable with the subjective anticipatory apposition, but not vice versa. Cf.:
I would consider it (this) a personal offence if they didn't accept the forwarded invitation. → It would be a personal offence (to me) if they didn't accept the forwarded invitation. You may depend on it that the letters won't be left unanswered. → It may be depended on that the letters won't be left unanswered.

The anticipatory appositive constructions, as is widely known, constitute one of the most peculiar typological features of English syntax. Viewed as part of the general appositive clausal system here presented, it is quite clear that the exposure of their appositive nature does not at all contradict their anticipatory interpretation, nor does it mar or diminish their "idiomatically English" property so emphatically pointed out in grammar books.
The unique role of the subjective anticipatory appositive construction, as has been stated elsewhere, consists in the fact that it is used as a universal means of rheme identification in the actual division of the sentence.
§ 8. Clauses of adverbial positions constitute a vast domain of syntax which falls into many subdivisions each distinguishing its own field of specifications, complications, and difficulties of analysis. The structural peculiarities and idiosyncrasies characterising the numerous particular clause models making up the domain are treated at length in grammatical manuals of various practical purposes; here our concern will be to discuss some principal issues of their functional semantics and classification.
Speaking of the semantics of these clauses, it should be stressed that as far as the level of generalised clausal meanings is concerned, semantics in question is of absolute syntactic relevance; accordingly, the traditional identification of major adverbial clause models based on "semantic considerations" is linguistically rational, practically helpful, and the many attempts to refute it in the light of the "newly advanced, objective, consistently scientific" criteria have not resulted in creating a comprehensive system capable of competing with the traditional one in its application to textual materials.
On the other hand, it would be a mistake to call in question the usefulness of the data obtained by the latest investigations. Indeed, if their original negative purpose has failed, the very positive contribution of the said research efforts to theoretical linguistics is not to be overlooked: it consists in having studied the actual properties of the complicated clausal system of the sentence, above all the many-sided correlation between structural forms and functional meanings in the making of the systemic status of each clausal entity that admits of a description as a separate unit subtype.

Proceeding from the said insights, the whole system of adverbial clauses is to be divided into four groups.
The first group includes clauses of time and clauses of place. Their common semantic basis is to be defined as "localisation" — respectively, temporal and spatial. Both types of clauses are subject to two major subdivisions, one concerning the local identification, the other concerning the range of functions.
Local identification is essentially determined by subordinators. According to the choice of connector, clauses of time and place are divided into general and particularising. The general local identification is expressed by the non-marking conjunctions when and where. Taken by themselves, they do not introduce any further specifications in the time or place correlations between the two local clausal events (i.e. principal and subordinate). As for the particularising local identification, it specifies the time and place correlations of the two events localising the subordinate one before the principal, parallel with the principal, after the principal, and possibly expressing further subgradations of these correspondences.
With subordinate clauses of time the particularising localisation is expressed by such conjunctions as while, as, since, before, after, until, as soon as, now that, no sooner than, etc. E.g.:
We lived here in London when the war ended. While the war was going on we lived in London. We had lived in London all through the war until it ended. After the war ended our family moved to Glasgow. Etc.
With clauses of place proper the particularising localisation is expressed but occasionally, mostly by the prepositional conjunctive combinations from where (bookish equivalent — whence) and to where. E.g.:
The swimmers gathered where the beach formed a small promontory. The swimmers kept abreast of one another from where they started.
For the most part, however, spatial specifications in the complex sentence are rendered not by place-clauses proper, but by adverbial-appositive clauses. Cf.: We decided not to go back to the place from where we started on our journey.
From the functional point of view, clauses of localisation

should be divided into "direct" (all the above ones) and "transferred", the latter mostly touching on matters of reasoning. E.g.:
