To change an affirmative sentence into a negative one, we generally add 'not' to the auxiliary verb. However, when words like 'always' are present, simply adding 'not' might change the meaning. We need to ensure that the negation correctly conveys the opposite of the original statement. The opposite of "always" is not necessarily "never"; it can also be "not always" or "sometimes not".
Correct Option: B) He is not always late to office.
This sentence correctly negates the original statement. "He is always late" means 100% of the time he is late. "He is not always late" means it's not 100% of the time; he might be late sometimes, but also on time sometimes. This is the direct negation.
To form the negative of a simple present tense sentence, we generally use the auxiliary verbs 'do' or 'does' followed by 'not' and the base form of the main verb. The choice between 'do' and 'does' depends on the subject of the sentence.
Correct Option: C) She doesn't like sweets.
To form a negative sentence from a simple present tense affirmative sentence, we generally use the auxiliary verb "do" (or "does" for third-person singular subjects) followed by "not" and the base form of the main verb. The given sentence "I know the answer" is in the simple present tense.
Correct Option: B) I don’t know the answer.
To form the negative of a simple present tense sentence, we typically use the auxiliary verb "do" (or "does" for third-person singular subjects) followed by "not" and the base form of the main verb. The original sentence "She sings well" is in the simple present tense.
Correct Option: A) She doesn’t sing well. This option correctly uses the auxiliary verb "does" (contracted to "doesn't") with "not" and the base form of the verb "sing" to form the negative of the simple present tense sentence.
To change an affirmative sentence into a negative one, we generally add "not" after the auxiliary verb (like 'is', 'are', 'am', 'was', 'were', 'has', 'have', 'had', 'will', 'shall', 'can', 'may', 'must', 'should', 'would', 'could', 'might'). In the given sentence, "They are friends," 'are' is the auxiliary verb.
A) They aren't friends. This option correctly places "not" (in its contracted form "n't") after the auxiliary verb "are," forming a grammatically correct negative sentence.
To change a simple present tense affirmative sentence into its negative form, we generally use the auxiliary verbs 'do' or 'does' followed by 'not' and the base form of the main verb. The choice between 'do' and 'does' depends on the subject of the sentence.
Correct Option: B) I do not agree with you.
