Exam Tips
- Cross out prepositional phrases to identify the true subject
- Remember that indefinite pronouns (some, any, none, all, most) can be singular or plural depending on the prepositional phrase that follows
- Practice identifying subjects in inverted sentences and sentences beginning with adverbs
Key Points
- Every sentence must have a subject (naming part) and predicate (telling part)
- Subject can be a noun, pronoun, noun phrase, gerund, infinitive, or noun clause
- Three types of subjects: complete subject (with modifiers), simple subject (single word), compound subject (two or more subjects joined by conjunctions)
- Subject-verb agreement is essential for grammatically correct sentences
- Prepositional phrases between subject and verb can create confusion - always identify the true subject

Exam Strategy
Focus on identifying subjects and verbs first, then analyze phrase relationships. Practice crossing out prepositional phrases to avoid agreement errors.

Remember that CSE exams often test practical application rather than theoretical knowledge, so practice with realistic sentence examples.
Quick Review Questions
Identify the simple subject in: 'The CEO's extensive collection of vintage cars attracts many visitors.'
The simple subject is 'collection' - the single noun that performs the action. 'The CEO's extensive' and 'of vintage cars' are modifiers.
What type of sentence is: 'Although she studied hard, Maria failed the exam, but she will retake it next month.'?
This sentence has one dependent clause ('Although she studied hard') and two independent clauses ('Maria failed the exam' and 'she will retake it next month').
Correct this run-on sentence: 'The weather was perfect, we decided to have a picnic.'
The comma splice is corrected by adding the coordinating conjunction 'so' or by using a semicolon or period.
What is the function of the noun phrase 'the talented young musician' in: 'The judges chose the talented young musician as the winner.'?
The noun phrase receives the action of the verb 'chose' and answers 'whom did they choose?'
Identify the adverbial phrase and its type in: 'She completed the project in record time.'
This prepositional phrase functions as an adverb answering 'how' she completed the project.
