Verb Test - 88

Auxiliary verbs are helping verbs that add some meaning to the clauses in which they appear. They almost always (except in some cases) appear with the verb.

An auxiliary verb is a verb that is used along with another main verb to form tenses, negatives, and questions. Examples are: 'be', 'have' and 'do'. It usually comes before the main verb.  

The auxiliary verb, 'have' is used to form perfect tenses or used with the infinitive to express an obligation (Example: I have to be there). In the given sentence, the clause, '_____ he know' is in simple present tense form and not in the perfect tense. There is no infinitive or obligation. Hence, the auxiliary verb, 'have' cannot be used. Hence, both options C and D are incorrect. 

The clause, "_____ he know' is an interrogative in the simple present tense. The appropriate form of the auxiliary verb, 'do' is used in the interrogative of simple present and simple past tenses. So, the answer is either 'do' or  'does'. If the subject is in the third person singular form, the auxiliary verb, 'does' is used. Otherwise, 'do' is used. Here the subject is 'he', which is in the third person singular form. Hence, option B is the correct answer and option A is incorrect. 

The sentence is a question and it is in the past perfect tense. From the options given, option D) have is the only appropriate answer in the same tense. Also, we need to use a word that is in the third person participle and so option A) is incorrect. Options B and C are in the present tense and option B) does is also commonly used in negative questions. Hence, both are incorrect.

Auxiliary verbs help form the various tenses, moods, and voices of other verbs.

The sentence mentions that the 'they' own a house in Shimla. From the given options, was and were are past tense (singular and plural respectively) of the verb 'be' and so options A and B are incorrect. option D) 'is' indicates third person state in present and so is incorrect. Option C) 'have' is used to show someone owns or possesses something. Therefore, the correct answer is option C) have and the complete sentence is: They have a house in Shimla.

The sentence uses the word 'every' is used before the subject i.e boy indicates the singularity of the verb. Therefore, the correct word is option C) has. Option A) does is an auxiliary verb but incorrect to be used in the context of the sentence as you cannot 'do' books, pens and pencils. Option B) have and option D) are are used in case of more than one subject or object.  Hence they are incorrect.

The auxiliary verb, 'do' is used to form the negative and interrogative form of the simple present/ past tense. (Example: Do you know?) It is used to emphasise the affirmative nature of a statement. (Example: You do look weak). It is also used in the imperative to make a request more persuasive. (Example: Do be quiet). The given sentence does not fall under any of the above categories. Hence, the options A and B (which are forms of the auxiliary verb 'do') are incorrect. 

The word, 'asking' is the present participle form of the verb, 'ask'. Hence, this sentence is in present perfect tense. The auxiliary verb, 'have' is used to form perfect tense. Hence, the answer is either 'have' or 'has'.

If the subject is in third person, singular form, the auxiliary verb, 'has' is used. Else, the auxiliary verb form, 'have' is used. Here the subject is 'My friends', which is in third person, plural form. Hence, 'has' cannot be used and 'have' is the suitable verb. Hence, option C is correct and Option D is incorrect.  

Choice C is correct as 'bleach' has a -ed,-ing and as simple present it stays the same.

The auxiliary verb, 'do' is used to form the negative and interrogative form of the simple present/ past tense. (Example: Do you know?) It is used to emphasize the affirmative nature of a statement. (Example: You do look weak). It is also used in the imperative to make a request more persuasive. (Example: Do be quiet). The given sentence does not fall under any of the above categories. Hence, the options A and B (which are forms of the auxiliary verb 'do') are incorrect. 

The auxiliary verb, 'have' is used to form the perfect tense.The word, 'arrived' is the present participle form of the verb, 'arrive'. Hence, this sentence is in the present perfect tense. Hence, the answer is either-'have' or 'has'.

If the subject is in the third person singular form, the auxiliary verb, 'has' is used. Otherwise, the auxiliary verb, 'have' is used. Here the subject is 'The train', which is in the third person, singular form. Hence, 'have' cannot be used and 'has' is the suitable verb. Hence, option C is incorrect and Option D is correct.
