Transformation of Sentences
Voice Change
Customer: Are vegetables sold here?
Grocer: Yes! We sell vegetables here.
Customer: Do you sell sugar?
Grocer: No, sugar is not sold here.
উপরের We sell vegetables here বাক্যটিতে দেখা যাচ্ছে We শব্দটি বাক্যের subject এবং vegetables বিক্রির কাজটি করেছে We। অর্থাৎ We হলো doer of the action। আবার, vegetables শব্দটি বাক্যে object এবং এটার উপর কাজটি করা হয়েছে। অর্থাৎ এটা receiver (গ্রহণকারী) of the action. কিন্তু সব সময় আমরা এভাবে বাক্য গঠন করি না। মাঝে মাঝে doer কে বাক্যের subject না করে receiver কে subject করা হয়। আর এভাবে উপরের বাক্যটিকে বললে বাক্যটি হতো:
Vegetables are sold here (by us).
এখন দেখা যাচ্ছে এ পরিবর্তনের ফলে বাক্যের অর্থগত পরিবর্তন হয়নি। শুধু structure (গঠন) পরিবর্তন হয়েছে। আর সে পরিবর্তনগুলো হলো:
(i) receiver টি subject হয়েছে
(ii) Subject এর পর অতিরিক্ত একটি 'be' verb বসানো হয়েছে।
(iii) মূল verb টির past participle করা হয়েছে।
(iv) by যোগে doer টি বসানো হয়েছে।
এভাবে আমরা বলতে পারি doer যখন sentence এর subject থাকে তখন তাকে active voice বলে। এবং receiver যখন sentence এর subject হয় তখন তাকে passive voice বলে।
Rules of Voice Change
Rule- 1: Receiver + সাহায্যকারী verb (যদি থাকে) + অতিরিক্ত be verb + মূল verb এর past participle + বাকি অংশ + by যোগে doer.
Rule- 2: Person ব্যবহারের নিয়ম:
Pronoun - এর subject ও object form ভিন্ন। তাই pronoun এর subject ও object form শিখতে হবে। নিচের ছকটি লক্ষ কর:
1st Person Singular => Subject: I => Object: me
1st Person Plural => Subject: We => Object: us
2nd Person Singular => Subject: You => Object: you
2nd Person Plural => Subject: You => Object: you
3rd Person Singular => Subject: He/ She/ It => Object: him/ her/ it
3rd Person Plural => Subject: They => Object: them
Example:
Active voice: I gave him a pen.
Passive voice: He was given a pen by me.
সাহায্যকারী verb গুলো হল:
Principal auxiliary: am, is, are, was, were, have, has, had (বাক্যে আছে বা ছিল অর্থে যখন ব্যবহৃত হয় তখন এগুলো মূল verb) do, does, did (না বোধক বা প্রশ্নমূলক বাক্য গঠনে ব্যবহৃত হলে)
Modal auxiliary: can, could, may, might, shall, should, will, would, had to, ought to, is going to
Semi - modals: need, dare, used
Rule- 3: অতিরিক্ত be verb - এর ব্যবহার:
অতিরিক্ত be verb - টি বসাবার সবচেয়ে সহজ উপায়:
❖ প্রদত্ত বাক্যে যদি have to, going to; এবং modal auxiliary থাকে তবে অতিরিক্ত be verb - টি অপরিবর্তিত বসে
❖ প্রদত্ত বাক্যে যদি be verb (be, been, am, is, are, was, were) থাকে তবে অতিরিক্ত be verb - টি being হবে
❖ প্রদত্ত বাক্যে যদি have, has, had থাকে তবে অতিরিক্ত be verb - টি been হবে
❖ কোনো সাহায্যকারী verb না থেকে যদি মূল verb - টি present হয় অতিরিক্ত be verb - টি Subject অনুযায়ী am/is/are হবে এবং মূল verb - টি যদি past হয় তবে অতিরিক্ত be verb - টি Subject অনুযায়ী was/ were হবে।
Active ⇒ Passive
They write a letter. ⇒ A letter is written by them.
এখানে মূল verb write এবং verb টি যেহেতু present form এ আছে তাই অতিরিক্ত be verb - টি present form গ্রহণ করে is হয়েছে।
They are writing a letter. ⇒ A letter is being written by them.
এখানে are থাকায় অতিরিক্ত be verb - টি being হয়েছে।
They have written a letter. ⇒ A letter has been written by them.
এখানে have থাকায় অতিরিক্ত be verb - টি been হয়েছে।
They have been writing a letter. ⇒ A letter has been being written by them.
এখানে been থাকায় অতিরিক্ত be verb - টি being হয়েছে।
They wrote a letter. ⇒ A letter was written by them.
এখানে মূল verb wrote এবং verb টি যেহেতু past form এ আছে তাই অতিরিক্ত be verb - টি was হয়েছে।
They should write a letter. ⇒ A letter should be written by them.
এখানে should থাকায় অতিরিক্ত be verb - টি be হয়েছে।
They are going to write a letter. ⇒ A letter is going to be written by them.
এখানে going to থাকায় অতিরিক্ত be verb - টি be হয়েছে।
Rule- 4: Receiver/ Object চেনার উপায়:
মূল verb - এর পরের noun/pronoun হল Object। Verb - কে কাকে/কী/ কারা দিয়ে প্রশ্ন করলে Object পাওয়া যায়। তবে মূল verb এর পরে যদি participle (ing যুক্ত/ ed যুক্ত) বা infinitive (to+verb) বা preposition (বিশেষ করে of) যুক্ত কোনো অংশ থাকে তখন পুরো অংশটাই subject হিসাবে ব্যবহার করতে হবে।
ing যুক্ত:
Active: He knows a boy reading at Dhaka University.
Passive: A boy reading at Dhaka University is known to him.
ed যুক্ত:
Active: I bought a shirt made in China.
Passive: A shirt made in China was bought by me.
Preposition যুক্ত:
They entertained the guests of the bridal party heartily.
The guests of the bridal party were entertained heartily by them.
Rule- 5: Extension (modifier of verb) চেনার উপায়:
verb - এর কাজ কোথায়/ কখন/ কীভাবে/ কেন হল - - - - এমন তথ্য প্রকাশক শব্দ বা শব্দ সমষ্টি হলো extension।
Active: I found a man in the field.
Passive: A man was found in the field by me.

Passive: Frugality should be practiced by everyone to make a well planned family.
Active: The farmers use water in time of cultivation largely.

Rule- 6: একটি বাক্যে দুটো (object of verb) থাকলে:
(a) Indirect object (অর্থাৎ প্রাণী/ব্যক্তিবাচক) কে subject করা শ্রেয়।
Active: I gave him a book.
Passive: He was given a book by me.
(b) অন্য object টিও subject হতে পারে, তবে এক্ষেত্রে direct object এর পূর্বে অর্থানুসারে অতিরিক্ত to/for বসাতে হবে।
Active: I gave him a book.
Passive: A book was given to him by me.
Active: I bought him a book .
