English Preparation

Students can refer to the following books to study Compound words:

Compound words are divided into three types based on the way they are written.

Some examples of auxiliary verbs include:

• She is cooking dinner for us tonight.
• Does he play the ukulele?
• They have finished the assignment.
• He was reading a book during lunchtime.
• I did call you last night.

Modal verbs are placed right before the base form of the main verb in a sentence and help express possibility, ability, or necessity. Note that the main verbs used after the modal verbs do not take '-s', '-es', or '-ing' at the end of the verb.

Examples:

• She can sing beautifully.
• It might rain later today.
• He should apologize for his bad behavior.
• You must complete your work before the deadline.

Some examples of modal verbs include:

• She can solve this puzzle within one minute.
• He may come late to the meeting.
• You must wear a seatbelt while driving.
• I would love to visit South Korea.
• You should study regularly.

Auxiliary Verbs or Primary Helping Verbs are the verbs used with main verbs to express different voices, questions, tenses, and negations in a sentence. These include different forms of Be, Have, and Do, such as is, am, are, be, been, being, do, did, does, was, and were.

The past perfect tense can be used in four forms:

• Affirmative: Subject + had + past participle of verb + object.
• Negative: Subject + had + not + past participle of verb + object.
• Interrogative: Had + subject + past participle of verb + object.
• Negative + Interrogative: Had + subject + not + past participle of verb + object.

Have a look at the examples of the past perfect tense below:

• The movie had already started when we arrived at the theatre.
• The teacher had scolded him as he misbehaved.
• Had the movie begun already?
• Had he not finished playing football before dinner?
• Sheetal had gone to the market when the incident happened.

As per the English Grammar rule for Past Perfect tense, the sentences in this verb form are formed using had with past particple (ed) of the verb. The Past Perfect tense rule or formula is:

Subject + Had + Past Participle of Verb + Object 

Past Perfect tense in English grammar is used to describe an action that was completed before another action in the past. The sentences in Past Perfect tense are formed using had + past participle (ed). Have a look at a few Past Perfect Tense examples below:

·       The path is broken as it had rained all night yesterday.

·       Had the Police arrived on time the robbery could be prevented?

·       She had left early yesterday because of the event.
