Complex Sentence
There are five types of subordinate clauses in English: the subject, the predicative, the attributive, the object and several types of adverbial clauses.
In English grammar, all the clauses are subdivided into three main groups: noun clauses, adjective clauses and adverb clauses.
The Noun clauses include three types of subordinate sentences such as the subject clause, the predicative clause and the object clause. Usually in subordinate clauses we use the direct word order but in some cases we may face a particular version of inversion. Also, different subordinate clauses need to be introduced by different introductory words which cannot be omitted.
Try the challenge to figure out what all this is about!
Conditional Subjunctive
Subjunctive mood is represented by three main forms in contemporary English: present subjunctive, past subjunctive, past perfect subjunctive. Other forms such as present continuous subjunctive and past continuous subjunctive are used very rarely.

Apart from the aforementioned, advanced students are particularly interested in the accurate usage of such verbs as should, would, could, might, wish after if and in the case when it is omitted in the mixed type conditionals.

Inversion
Inversion is the change of a standard word order from subject-verb to verb-subject. If there is more than one verb, only the first auxiliary verb swaps places with the subject. Inversion is usually used in questions, but there are a number of other scenarios in which it applies. It is often used to make the speech more emphatic.
Inversion is not used a lot in everyday colloquial speech, it sounds a bit bookish and will remind people of Shakespeare's times.
Hardly it makes knowledge of the rules of inversion less important for advanced students, does it?

Sequence of Tenses in Indirect Speech
Understanding the principle of the sequence of tenses in direct and indirect speech must not be a great challenge!
However, the devil is in the details, exceptions and rules variations, not to mention indirect sentences with modal verbs and the usage of adverbs of time and place, which in turn must be changed in a special way.
Special Constructions
In English there are some verb constructions having special indirect meaning, such as used to, would, get used to, get doing, be to do, happen to do, be going to do something, be about to do something etc.
For example "I would go swimming to the swimming pool in my childhood" – means that in the past I went to swim periodically but now I don't go swimming anymore...
These constructions help to add different shades to the main meaning of a sentence without wordy explanations. Now, how about getting answering the questions?
