Clauses, Conditionals & Prepositions: Rules, Uses & Exam Tricks

TAKEAWAYS:

• Clauses are groups of words with a subject and verb: independent clauses can stand alone, while dependent clauses (subordinate clauses) need help to make sense.
• Conditionals show hypothetical situations: zero (always true), first (real possibility), second (unreal), and third (past unreal) types follow strict verb patterns.
• Prepositions link nouns/pronouns to other words (e.g., in, on, at, by). Misuse (e.g., on time vs. in time) is a common NEB error.
• Complex sentences combine clauses using conjunctions (and, but, because) or subordinators (if, although, because).
• Conditionals require if + past simple (second type) or if + had + past participle (third type) for unreal situations.
• Prepositions are tricky—learn fixed phrases (e.g., interested in, afraid of) and avoid mixing them up.

1. Clauses: The Building Blocks of Complex Sentences

A clause is a group of words with a subject and a verb. Clauses can be:

• Independent (main) clauses: Can stand alone as a complete sentence. Example: She studied hard. (Complete thought)
• Dependent (subordinate) clauses: Cannot stand alone; they need a main clause to make sense. Example: because she wanted to pass (Needs a main clause: She studied hard because she wanted to pass.)

Types of Clauses

How to Identify Clauses

• Look for subordinating conjunctions (if, because, although, when, where, who, which, that). Example:
  • If you study, you will pass. (If you study = dependent clause)
  • She passed because she studied. (because she studied = dependent clause)

Joining Clauses

Use conjunctions (and, but, or) or subordinators (if, although, because) to combine clauses.

• Coordinating Conjunctions (FANBOYS: for, and, nor, but, or, yet, so) Example: She worked hard, but she failed. (Two independent clauses joined by but)
• Subordinating Conjunctions Example: Although it rained, we went out. (Although it rained = dependent clause)

Common Mistakes

❌ Because she was sick, she went to school. (Incorrect—dependent clause first!) ✅ She went to school although she was sick. (Correct)

2. Conditionals: Hypothetical Situations

Conditionals express real or unreal situations. There are four types, each with a specific structure.

Types of Conditionals

Key Rules

1. Second Conditional:
   • Use were (even for I/he/she): If I were you...
   • Would is the main verb: I would help if I could.
2. Third Conditional:
   • Had + past participle in the if clause.
   • Would have + past participle in the main clause.
3. Mixed Conditionals (uncommon in NEB):
   • Combine types (e.g., If I had known earlier, I would be happy now.)

Worked Example: Fixing Errors

❌ If she will come, I will tell her. ✅ If she comes, I will tell her. (First conditional)

❌ If I was rich, I would buy a car. ✅ If I were rich, I would buy a car. (Second conditional)

❌ If he had known, he doesn’t come. ✅ If he had known, he wouldn’t have come. (Third conditional)

3. Prepositions: The Glue of the English Language

Prepositions show relationships between words (time, place, direction, etc.). Common prepositions:

• Time: in, on, at, by, during, before, after
• Place: in, on, at, under, over, above, below
• Direction/Movement: to, from, into, out of, across, through
• Other: with, without, about, for, of, by

4. Combining Clauses and Conditionals in Sentences

Example 1: Complex Sentence with Clauses

• Simple Sentences:
  • She worked hard.
  • She passed the exam.
• Combined with because:
  • She passed the exam because she worked hard. (because she worked hard = adverb clause)

Example 2: Conditional + Clause

• Second Conditional:
  • If I were you, I would study more. (If I were you = dependent clause)
• Third Conditional:
  • If she had listened to the teacher, she wouldn’t have failed. (If she had listened = dependent clause)

Example 3: Mixed Clauses and Conditionals

• Although it was raining, we went out because we didn’t want to miss the match.
  • Although it was raining = adverb clause
  • we didn’t want to miss the match = main clause

Exam Tip: How to Score Full Marks in NEB Grammar

1. Clauses:

   • Identify dependent vs. independent clauses in questions.
   • Use subordinating conjunctions (if, because, although) correctly.
   • Avoid comma splices (two independent clauses joined by a comma only).

2. Conditionals:

   • Memorize the structures of all four types.
   • Second conditional: Always use were (even for I/he/she).
   • Third conditional: Had + V3 in the if clause, would have + V3 in the main clause.
   • Watch for mixed conditionals (rare but possible).

3. Prepositions:

   • Learn fixed phrases (afraid of, interested in, good at).
   • Time prepositions: at (exact time), on (days/dates), in (months/years).
   • Place prepositions: in (cities/countries), at (small places), on (surfaces).
   • Practice common errors (e.g., on time vs. in time).

4. General Tips:

   • Underline clauses in complex sentences to identify their type.
   • For conditionals, write the structure first before filling in blanks.
   • Prepositions: If unsure, eliminate wrong options (NEB often gives tricks like afraid of/from).
   • Proofread: Check for subject-verb agreement and preposition errors last.
