Explanation

This is a first conditional sentence, used for real or likely future situations: If + present tense, will + base verb.

"Will cook" correctly follows the structure: If you wash..., I will cook....

Explanation

"Had been working" is used for an action that started in the past and continued up to another point in the past.

Since 2010 indicates a time duration, which suits the past perfect continuous tense.

Explanation

The phrase "last night" indicates past tense.

So, the correct verb form is "went", the past tense of "go".

Explanation

 "Tooth and nail" is an idiom that means to fight very fiercely or with great determination.

Explanation

Reported speech requires correct tense and structure.

After "He told us", we use "that" + past tense if the reporting verb is in the past.

"Enjoyed" matches the past tense of "told."

Correct sentence: He told us that he enjoyed the movie.

Explanation

The sentence is in the past tense ("Everything was going well"), so the correct form is "didn't have" (past simple negative).

"Didn't" is used with the base form of the verb ("have").

Explanation

The correct preposition to show who performed the action is "by" in passive voice.

Sentence: He was excluded from the team by his supervisor.

Explanation

"He has not met his mother for the last two years."

Use "for" to indicate a duration of time.

"The last two years" refers to a period, so "for" is the appropriate preposition.

 Incorrect: He has not met his mother since the last two years.

(This structure would require a specific starting point, like "since 2023.")

Explanation

Explanation

The sentence refers to last night (past tense), so use "was" with "I" for past continuous tense:

I was watching TV last night.
