The document discusses how to join two sentences using an "if clause". It provides an example of joining the sentences "I didn't know it was hot" and "I didn't bring the umbrella" into the single sentence "If I had known it was hot, I would have brought the umbrella". It notes that the tense and polarity of the original sentences determines how the joined sentence is constructed. Part II will provide more examples and practice joining sentences with if clauses.

2. Let us study the following sentences:
I didn’t know it was hot. I didn’t bring the umbrella.
If we are asked to rewrite the above two sentences into one
sentence using ‘if clause’ then we need to see the following:
a) Tense of both the sentences.
Both the sentences are in Past tense. Hence the sentence that
we write in ‘if clause’ should be in unfulfilled condition. To
express this we follow the following structure.

3. Structure:
Subordinate Clause (If – Clause)
If + subject + past perfect tense of the verb +
Main Clause:
Subject + would have/could have/should have/might have +
Past Participle of the verb +
I didn’t know it was hot. I didn’t bring the umbrella.
Let us join both the sentences using ‘if clause’.
If I had known it was hot, I would have brought the
umbrella.

4. NOTE:
If both the given sentences are negative then in answer both
the sentences would be in positive.
If both the given sentences are positive then in answer both
the sentences would be in negative.
If one sentence is positive and other one is negative then in
answer the positive sentence would become negative and
the negative sentence would become positive.
