❓ Frequently Asked Questions (FAQ)
FAQ 1
What is sentence completion?
Show Answer
Answer: It is an exercise where you are given part of a sentence and must add the correct word, phrase, or clause to complete it meaningfully and grammatically.
FAQ 2
What skills does sentence completion test?
Show Answer
Answer: It tests grammar (conjunctions, tenses, prepositions), vocabulary (collocations, fixed expressions), and the ability to understand logical relationships between ideas.
FAQ 3
How can I do well in sentence completion exercises?
Show Answer
Answer: Read the whole sentence to understand what is missing— is it a reason, a result, a contrast, a condition? Then choose the connector or structure that fits that logic. Practise common patterns like "no sooner...than", "so...that", "although...yet", "unless", "as long as", etc.
FAQ 4
What is the difference between gap filling and sentence completion?
Show Answer
Answer: Gap filling usually involves a single blank in a sentence where a specific word (preposition, article, tense) is needed. Sentence completion often requires a longer fragment—a clause or a phrase—that completes the idea logically.
FAQ 5
Are sentence completion questions asked in competitive exams?
Show Answer
Answer: Yes, they appear in exams like SAT, TOEFL, bank exams, and various university entrance tests. They assess your understanding of sentence structure, logic, and grammar.
