1.
The pollution is one of the most serious problems in the world. (Wrong use of article)
Explanation
You don't use 'the' when you talk about things in general. E.g., Money doesn't buy happiness. (Money and happiness in general).
2.
These vehicles produces exhaust fumes. (Wrong verb form)
Explanation
'These vehicles' is plural, so the verb should be in the plural, too.
3.
The government must provide a solution before is too late. (A word has been omitted)
Explanation
The sentence "The government must provide a solution before it is too late" was missing the word "it," which serves as a pronoun referring back to the time frame before a negative consequence becomes unavoidable. Including "it" makes the sentence grammatically complete, clarifying that action is required within a specified window to prevent undesirable outcomes. This use of "it" emphasizes urgency and the need for timely intervention by the government.
4.
The second problem is the extremely destruction of rainforests. (Wrong use of adverb/adjective)
Explanation
You use an adverb ('extremely', 'really', 'incredibly', etc) before a verb or another adjective. E.g.: An incredibly exciting story; a really dramatic film. He sang beautifully; I came up with an answer quickly.
5.
Wich (Wrong spelling)
6.
Enviroment (Wrong spelling)
Explanation
The correct answer is "environment". The word is spelled with an "n" instead of an "m". The correct spelling refers to the surroundings or conditions in which a person, animal, or plant operates or exists. The incorrect spelling "enviroment" is a common misspelling of the word.
7.
Lost (Wrong spelling for noun)
Explanation
'lost' is the past simpke and past participle of 'lose'. The noun is 'loss'.
8.
I found really interesting the classes. (Wrong word order)
Explanation
The correct answer is "I found the classes really interesting." The original sentence has incorrect word order, with "really interesting" placed before "the classes." In English, it is more common to place adjectives after the noun they modify. Therefore, the correct sentence should be "I found the classes really interesting."
9.
I'm boring because there's nothing exciting to do. (Wrong spelling)
10.
I told to my friends to go to the cinema. (Unnecessary preposition)
Explanation
The given sentence "I told to my friends to go to the cinema" contains an unnecessary preposition "to" before the object "my friends". The correct sentence should be "I told my friends to go to the cinema" which omits the unnecessary preposition. The answer given is also correct as it provides the corrected sentence without the unnecessary preposition.
11.
This restaurant is near to the riverside. (Wrong preposition)
12.
She has visited her friends last week. (Wrong verb tense)
Explanation
The original sentence uses the present perfect tense ("has visited"), which implies an action that started in the past and continues to the present or has relevance to the present. However, the time frame mentioned is "last week," indicating a completed action in the past. Therefore, the simple past tense ("visited") is more appropriate to describe the action accurately.
13.
He studied English since he was 10. (Wrong verb tense)
Explanation
You use the present perfect simple or continuous with 'since, for, already, yet, how long', and when the action is still being done and/or has a consequence in the present.
14.
He was so much interested in the book that he didn't hear the noise. (Grammar error)
Explanation
You use 'so much' to refer to quantity, and you use it after uncountable nouns. E.g.: I don't have so much money. I like him so much!
15.
Thanks for invite me to the cinema. (Wrong verb form)
Explanation
The original sentence uses the present tense verb "invite," which is incorrect because the act of inviting has already happened. To convey that the invitation occurred in the past, the past tense form "inviting" should be used. This grammatical correction ensures the sentence accurately reflects the timeline of events, with the act of thanking following a prior invitation.
