We've discussed a good number of items relating to grammar and vocabulary. Now let's see how we can frame/form/construct sentences. The method is simple. The basic structure of a sentence in English is as follows:
Subject + Verb + Extn* [This extension may be a complement* or an object.]
 HeShe       is       a student/happy/here. (Complement)
He/She    reads    a book. (Object)
*Complement == > Complement is what makes the sentence meaningful. Such as, if we say, 'He is.' questions arise 'What/How/Where he is.' But when we say 'a student', 'happy' or 'here', the meaning of the sentence becomes complete. So, we can say that complements are either a noun (a student), adjective (happy) or adverb (here) that helps to complete the meaning of a sentence. And we can symbolize them as Cn, Ca or Cadv.)
Now let's see how a sentence can be made to give full expression of our thought. Look below:
He is a student. (A)
He is a student of class VII. (B)
He is a student of class VII of this school. (C)
He is a meritorious student of class VII of this school. (D)
He is a very meritorious student of class VII of this school. (E)
So, you see that you can make a sentence just by putting the required words in their right places. And what is the right place/position of a 'word'? It depends which part of speech the 'word' is. If it's a noun, it comes after the verb in a statement sentence. If it's an adjective it may be used as in A, Ot it may come before a noun as in D. Again, if it's an adverb, it can be used after the verb as in A. Or it may, in most cases, come at the end of the sentence when there is an action* verb. For example: He reads slowly. She sings sweetly. They fought bravely.
N.B.:- Usually, adjective of quality + ly = adverb of manner. Such as - nice > nicely. brave > bravely, sweet > sweetly.
Of course adverbs are of several kinds; such as adverbs of manner (how something is done), adverbs of time (when something is done), adverbs of place (where something is done), adverbs of degree (to indicate how much the adverbs of manner done). Usually, these different kinds of adverbs are used as follows. Observe carefully.
He does his lessons attentively. (manner)
He does his lessons very attentively. (degree)
He does his lessons in the morning very attentively. (time)
He does his lessons at home very attentively. (place)
By the way, there is another kind of adverb called adverb of frequency which we'll discuss later.
That's all for now friends. Feel free to ask any question. Good night and good bye.
