Future Perfect Tense

Because "will have changed" follows the Future Perfect structure:

will + have + past participle (changed).

It expresses an action that will be completed before a specific future time.

Explanation

I am reading the book

"I" → requires "am"

Explanation

Look! The bus is leaving!

We use the present continuous tense (is + verb-ing) for actions happening right now,

Explanation

 "He called me last night."

اس نے مجھے کل رات بلایا۔

"He" is the subject pronoun (the one doing the action).

"Me" is the object pronoun (the one receiving the action).

Explanation

 He is very careful. He does not allow his children to drive his car in rush hour traffic.

وہ بہت محتاط ہے۔ وہ اپنے بچوں کو رش کے اوقات میں گاڑی چلانے کی اجازت نہیں دیتا۔

The sentence is in the present tense — indicated by: "He is very careful..."

So, the next part must also be in the present tense.
