Sentence Correction

• If I am in Lahore, I will contact you.

Explanation

There are two errors in this sentence: one is related to the use of conditional sentences, and the second is related to prepositions.

Error 1: Incorrect Use of “Will” in the If-Clause

In conditional sentences, we do not write “will” in the if-clause (the part after “if”) when referring to a future event.

Instead, we use the present simple or indefinite tense in the if-clause and the future tense (will + verb) in the main clause.

Error 2: Incorrect Use of “Contact to You”

I taught you that the verb “contact” is not followed by the preposition “to” in English.

It is a transitive verb, meaning it takes a direct object.

So, replace “Will” from the first clause and “To” from the second clause to fix the errors.

Sentence Correction

If I'm stressed out about something, I tend to have a problem falling asleep.

Explanation

This sentence contains two errors: one, grammatical “have problem”; second, contextual “problem to fall”. If you want to score full marks, you need to correct them.

Error: Incorrect Use of “Problem”

The phrase “have a problem” is incorrect for two reasons:

1. Singular Noun Issue

   The word “problem” is a countable noun, so if you use it in the singular form, it must have an article (“a” or “the”).

2. “Problem” Is Not Naturally Followed by “To + Verb”

   We don’t typically use “problem” with an infinitive (to + verb). Instead, we use a gerund (-ing form) or a gerund phrase after it.

   I have a problem to sleep. (Incorrect)

   I have a problem sleeping. (Correct)
