আমি তাকে পড়তে শুনলাম।

• Hear somebody/something doing something:
- I heard him reading.
- Jenny could hear them arguing outside.

• Hear somebody do something:
- She heard Tom go upstairs.
- Did you hear him go out?

অর্থাৎ বোঝা যাচ্ছে Hear somebody doing something এর পর verb + ing বসে।
তাই প্রদত্ত বাক্যের সঠিক অনুবাদ হচ্ছে I heard him reading.
