When using articles, there are a number of ways to communicate specific shades of meanings with articles. Related rules for proper names don't make things easier. To complicate things even further, there are other determiners occasionally taking the place of articles. For instance, some and no function like articles, but behave somewhat differently with uncountable nouns.

Very often when we compare different objects or events. As we tend to be as colorful as possible, using only comparative or superlative form of adjectives is not always enough.

Because of this, we begin to add adverbs or special constructions such as far, by far, much, a lot, a little etc.

The knowledge of the rules how to use the intensifiers of comparison usually indicates an advanced student.

There are five types of subordinate clauses in English: the subject, the predicative, the attributive, the object and several types of adverbial clauses.

Adverbials happen to be the thing this challenge is about.

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.

These subordinate clauses may be divided into 4 types according to the realness of the condition and the time.

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.

All this is simple and clear for you, and you would easily prove it passing a test on the subject, wouldn't you?

There are some verbs in English that need different type of objects: either gerunds or infinitives. In order not to make a mistake students usually learn these verbs by heart. Besides, there are also such verbs that may be followed by both gerunds and infinitives, and the choice of the object type directly influences the meaning of a sentence.

Of course there are not so many verbs such as “forget” in English, but the reason for the choice of the infinitive or the gerund object each time will be different and will strongly influence the meaning of a sentence. And it’s a real challenge for advanced students.

Speaking about the challenge, did you forget... ehm... nervermind...

Complex participles and gerunds, their perfect, passive or perfect-passive forms are interesting. The accurate understanding and usage of such participial nad gerund constructions especially after the verb to be and different prepositions; before nouns; and also in set expressions and constructions shows... shows...

Actually, go and try to figure it out yourself.

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.

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?

All English verbs are divided into three big groups of transitive, intransitive and linking verbs. The belonging to one of these groups influences the choice of the object the verb may be followed by: direct, indirect, indirect without a preposition, prepositional object or the complex object. Another reason to know about "transitivity/intransitivity" of a verb is to be able to use the verb in the passive voice. In addition, some verbs such as get, grow, keep, look, and alike, can be also link verbs that will strongly influence the meaning of a sentence.
