📚 Understanding Sentence Structure
Every English sentence follows a basic structure. Understanding it is essential for BCS, IELTS, Bank Jobs, HSC, and university admission.
(প্রত্যেকটি ইংরেজি বাক্য একটি মৌলিক গঠন অনুসরণ করে। এটি বোঝা অত্যন্ত গুরুত্বপূর্ণ।)
📌 Basic Sentence Structure
Most English sentences follow this pattern:
📝 Subject + Verb + Object
উদ্দেশ্য + ক্রিয়া + কর্ম
Component
Example
Bangla
Subject
Rahim, She, The book
রহিম, তিনি, বইটি
Verb
reads, is, writes
পড়ে, হয়, লেখে
Object
a book, a letter
একটি বই, একটি চিঠি
📌 Types of Sentences
Simple Sentence: One independent clause. (একটি স্বাধীন উপবাক্য।)
📝 "Rahim reads a book."
"রহিম একটি বই পড়ে।"
Compound Sentence: Two independent clauses joined by a conjunction (and, but, or). (দুটি স্বাধীন উপবাক্য সংযোজক অব্যয় দ্বারা যুক্ত।)
📝 "Rahim reads a book and he writes a letter."
"রহিম একটি বই পড়ে এবং সে একটি চিঠি লেখে।"
Complex Sentence: One independent clause + one dependent clause. (একটি স্বাধীন + একটি পরাধীন উপবাক্য।)
📝 "Because Rahim reads a book, he is very smart."
"যেহেতু রহিম একটি বই পড়ে, সে খুবই স্মার্ট।"
📌 Active vs Passive Voice
Active: Subject performs the action. (উদ্দেশ্য কর্মটি সম্পাদন করে।)
📝 "Rahim reads a book."
"রহিম একটি বই পড়ে।"
Passive: Subject receives the action. (উদ্দেশ্য কর্মটি গ্রহণ করে।)
📝 "A book is read by Rahim."
"একটি বই রহিম দ্বারা পড়া হয়।"
