Error Detection

The correct form should be "He sings beautifully." The adjective "beautiful" needs to be in its adverb form "beautifully" to describe the verb "sings."

The correct sentence is "He doesn't like it." The auxiliary verb "doesn't" is used correctly with the base form of the verb "like."

The error is in "it's," which is a contraction for "it is" or "it has." The correct form should be the possessive "its."

The correct form is "She has watched it twice." The auxiliary verb "have" should be "has" to agree with the singular subject "She."

The correct sentence is "The team is playing well today." The adverb "well" is used to describe the verb "playing," and "is" agrees with the singular noun "team."

The correct sentence is "Neither John nor Mary was present." The verb should agree with the nearest subject, which is "Mary," and requires the singular verb "was."

The correct sentence is "He said that he would come." The verb "will" should be "would" for consistency in reported speech.

The correct sentence is "I am looking forward to meeting you." The verb "meet" should be in the gerund form "meeting" after the phrase "looking forward to."

The correct sentence is "She has gone to London." The past participle "gone" should be used with "has" instead of "went."

The correct sentence is "She did not hear the alarm." The base form of the verb "hear" should be used after "did not."

The correct sentence is "They have finished the project." The auxiliary verb "has" should be "have" to agree with the plural subject "They."

The correct sentence is "The dog barked loudly." The word order should be subject ("The dog") followed by the verb ("barked") and then the adverb ("loudly").

The correct sentence is "I must go now." The modal verb "must" is followed directly by the base form of the verb "go."

The correct sentence is "The team plays well together." The verb "plays" agrees with the singular noun "team."

The correct sentence is "There is good news for you." The noun "news" is uncountable and does not require an article like "a."

The correct sentence is "My father has two cars." The verb "have" should be "has" to agree with the singular subject "father."

The correct sentence is "She is taller than him." The comparative form "taller" does not need "more" before it.

The correct sentence is "Each student was given a book." The verb should be "was" to agree with the singular subject "Each student."

The correct sentence is "She was here yesterday." The verb "were" should be "was" to agree with the singular subject "She."

The correct sentence is "The sun sets in the west." The subject "The sun" should come before the verb "sets."

The correct sentence is "I have eaten already." The adverb "already" is typically placed between the subject and the verb or at the end of the sentence.

The correct sentence is "She drives carefully." The adjective "careful" should be in its adverb form "carefully" to describe the verb "drives."

The correct sentence is "Each of the books is interesting." The verb should be "is" to agree with the singular subject "Each."
