Simple sentence কে complex sentence এ পরিবর্তনের নিয়ম

Simple sentence কে complex sentence এ পরিবর্তনের জন্যে simple  sentence  এর একটা clause কে ভেঙে অথবা নতুন শব্দ যোগ করে দুইটা clause তৈরি করতে হবে। সেই দুইটি clause কে যোগ করতে হবে উপরোক্ত connectors গুলো ব্যবহার করে। এর জন্যে নির্দিষ্ট নিয়মগুলোর বাইরেও অনেকভাবে simple sentence কে complex sentence এ রূপান্তর করা যায় এবং সবগুলো নিয়মেরই ব্যতিক্রম নিয়ম আছে।

নিম্নোক্ত নিয়মগুলো সব ক্ষেত্রেই ব্যবহার করা যাবে :

Rule 1:

If there is an extra phrase in the simple sentence, expand that phrase to make a clause. Then choose a suitable connectors to connect the clauses.

Phrase  টিকে clause  এ রূপান্তর করার জন্যে একটি verb আনতে হবে এবং যদি subject না থাকে তাহলে একটা subject ও আনতে হবে।

Example: 

Simple: Seeing the teacher, the student stopped making noise.

এই sentence টিতে phrase হচ্ছে ‘Seeing the teacher’।  এই phrase এ seeing কে সহজেই verb বানানো যায়। আর যেহেতু এই sentence এর subject একটাই সেহেতু আমরা একই subject ব্যবহার করবো।
So, the two clauses we can get from this sentence are:
*The students saw the teacher ---- *The students stopped making noise.

Transformation এ tense পরিবর্তিত হয় না।  তাই আমরা seeing কে saw বানিয়েছি। দুটি clause এ subject যেহেতু একই, তাই একটিতে pronoun ব্যবহার করতে হবে। তারপর উপযুক্ত একটি connector বাছাই করতে হবে। এ ধরনের sentence  এর ক্ষেত্রে একের অধিক connector ও থাকতে পারে এবং সব গুলোই সঠিক।
The complex sentence could be:

·         As the student saw the teacher, they stopped making noise.

·         Since the student saw the teacher, they stopped making noise.

·         The students stopped making noises when they saw the teacher.

যদি clause  এবং phrase এর subject ভিন্ন ভিন্ন হয়, তাহলে দুই clause এর জন্যে দুই subject থাকবে।
Example: 
Simple: Alex could not go to school due to his mother’s illness.
Complex: Alex could not go to school because his mother was ill.
Or, Alex could not go to school since his mother was ill.

Rule 2:

If there is no extra phrase in the simple sentence, you have to find a word which you can expand into a clause. The word can be an adjective, noun, or adverb.

Example: 
Simple: He pleaded for his innocence.
Complex: He pleaded that he was innocence.
এখানে আমরা innocence শব্দটিকে সিলেক্ট করে একটি verb এনে আরেকটি clause তৈরি করেছি। innocence একটি noun, তাই এই clause  টি একটি noun clause .

More Examples of noun clauses in complex sentences: 
Simple: Murphy knows Mr. Rashid.
Complex: Murphy knows who Mr. Rashid is.
Simple: I prayed for your job.
Complex: I prayed so that you could get the job. (Connector – ‘so that’ requires the modal – ‘can/could’ in the following clause.)
(Note: Complex করার ক্ষেত্রে extra একটি verb আনা যাবে।)
Simple: He admitted his guilt.
Complex: He admitted that he was guilty.

For words that are adjectives, you have to make an adjective clause. 
Example:
Simple: He was an outstanding actor.
Complex: He was an actor who was outstanding.
এখানে outstanding শব্দটি একটি adjective এবং এই শব্দ কে কেন্দ্র করেই একটা clause তৈরি করা হয়েছে।

Complex: I lost the pen which was most beautiful.
Simple: He was a remarkable man.
Complex: He was a man who was remarkable.
Simple: I want an extensive encyclopedia.
Complex: I want an encyclopedia which is extensive.

For words that are adverbs, you have to make an adverb clause. 
Example:
Simple: He is too weak to carry this heavy bag.
Complex: He is so weak that he cannot carry that heavy bag.
Simple: He is working relentlessly to finish the work.
Complex: He is relentlessly working so that he can finish the work.
Simple: He was born in the year of liberation war.
Complex: He was born when it was the year of liberation war.
