7.2 Sentence Composition & Star-Question Strategies: 4-Phase Unscrambling, Left-Branching Relative Clauses & Mondai 2 Traps

Sentence Composition & Star-Question Strategies: 4-Phase Unscrambling, Left-Branching Relative Clauses & Mondai 2 Traps

Core Principle: Grammar Mondai 2 (文の組み立て - Sentence Composition) tests your deep structural grasp of Japanese sentence architecture. Instead of evaluating isolated grammar rules, it presents a sentence with four blank slots containing a star in the third position: _______ _______ __★__ _______. Your task is not merely to pick a word, but to reconstruct the entire syntactic tree and identify which of the four scrambled options occupies the third blank (★).

Mondai 2 carries about 4 questions on the current JLPT N4 exam (it was 5 before the December 2020 shortening, and many older prep books still say 5). Because 4 scrambled options yield 24 mathematical permutations (4! = 24), attempting trial-and-error reading in your head wastes precious time and induces cognitive fatigue. Applying a rigorous 4-phase unscrambling protocol guarantees 100% accuracy within 60 to 90 seconds per question.

1. The 4-Phase Unscrambling Methodology

To solve any Mondai 2 question with mathematical certainty, execute these four consecutive phases:

THE 4-PHASE UNSCRAMBLING PROTOCOL

  [Phase 1: Anchor Periphery] ──→ Check Sentence Opener & Sentence-Final Predicate
              │
  [Phase 2: Collocation Chunks] ──→ Lock 2-Piece Inseparable Pairs (Particle + Verb, Auxiliaries)
              │
  [Phase 3: Clausal Junctions] ──→ Connect Relative Clauses, Modifiers & Conjunctions
              │
  [Phase 4: Star Slot Extraction] ──→ Place Chunks into [1] [2] [★: 3] [4] & Mark Option Number

Phase 1: Anchor the Periphery (Frame Analysis)

Examine what precedes the first blank and what immediately follows the fourth blank:

• The Sentence Opener: Look for topic markers (〜は), temporal phrases (昨日、来週), or initial conditions (雨が降ったら). Identify what kind of grammatical element must immediately attach to it.
• The Sentence Closer: Look at the final predicate (e.g., 〜てください, 〜嬉しかったです, 〜つもりです, 〜お越しください). Determine what part of speech can precede it (e.g., a て-form verb, an adverb, a dictionary form + の/こと, or a specific particle like に/を).

Phase 2: Form 2-Piece Inseparable Collocation Chunks

Look at the four numbered options and immediately pair elements that grammatically demand each other:

• Particle + Verb / Adjective Valence: e.g., 「友達に」 + 「もらった」; 「部屋を」 + 「掃除した」; 「富士山に」 + 「登る」.
• Grammar Formula Pairs: e.g., 「話せる」 + 「ように」; 「買う」 + 「ために」; 「勉強し」 + 「ながら」; 「昨日」 + 「ほど」.
• Te-form Auxiliaries: e.g., 「書いて」 + 「おく」; 「食べて」 + 「しまう」; 「教えて」 + 「あげる」.

Forming two 2-piece chunks instantly reduces 24 permutations down to just 2 possible combinations (Chunk A-B vs. Chunk B-A)!

Phase 3: Connect Clausal Junctions & Relative Modifiers

Merge your 2-piece chunks using clause connectors:

• Conjunctive particles: から / ので (cause), のに / けれども (contrast), たら / と / ば / なら (conditionals).
• Relative clauses (連体修飾節): Verbs in plain form (辞書形, た形, ない形) directly preceding a head noun.

Phase 4: Star Position (★) Identification & Option Extraction

Assemble the full four-slot sequence [Slot 1] [Slot 2] [Slot 3: ★] [Slot 4]. Read the complete assembled sentence silently to verify natural prosody and logic. Extract the option number that sits in Slot 3.

2. Left-Branching Relative Clauses (連体修飾節) in Mondai 2

The single most frequent structural pattern tested in JLPT N4 Mondai 2 is the Japanese Relative Clause.

ENGLISH (Right-Branching) vs. JAPANESE (Left-Branching)

  English:  The camera  [that my father bought in Tokyo yesterday]
               (Head)       (Modifying Clause follows to the right)

  Japanese: [昨日 父が 東京で 買った]  カメラ
             (Modifying Clause on left)   (Head Noun)

Core Rules for Relative Clauses in Mondai 2:

1. Plain Form Predicate: The verb or adjective inside a relative clause is ALWAYS in the plain form (辞書形, た形, ない形, or な-adjective + な), never in ます/です form.
2. Subject Particle Shift (が ──→ の): Inside an embedded relative clause, the subject marker が frequently shifts to の without changing the meaning:
   • [父が作った] 料理 ＝ [父の作った] 料理 (The dish my father cooked).
   • [背が高い] 人 ＝ [背の高い] 人 (A person who is tall).
3. Spotting Relative Clauses in Options: Whenever you see a Plain Past Verb (〜た) or Dictionary Verb (〜る) among the options, immediately scan for a Head Noun in another option or in the peripheral frame to which it can attach.

3. Three Authentic Step-by-Step Worked Examples

Let us deconstruct three authentic JLPT N4 Mondai 2 challenges using the 4-phase protocol.

Worked Example 1: Relative Clause & Giving/Receiving

【Problem】
誕生日に _______  _______  ___★___  _______ 嬉しかったです。

Options:
  1: もらった
  2: 友達に
  3: プレゼントは
  4: とても

Step-by-Step Deconstruction:

• Phase 1 (Periphery):
  • Opener: 誕生日に (On my birthday...)
  • Closer: 嬉しかったです (I was happy / glad). The adjective 嬉しかった needs an adverb like とても or a clausal topic/cause.
• Phase 2 (Collocation Pairs):
  • Look at Option 2 (友達に) and Option 1 (もらった): 友達にもらった (received from a friend) is a rock-solid giving/receiving collocation chunk [2-1].
  • Look at Option 4 (とても) and the closing predicate 嬉しかったです: とても嬉しかったです [4-Closer] is natural.
• Phase 3 (Connecting Clauses & Nouns):
  • Option 1 is plain past もらった. It must modify a head noun. Option 3 is プレゼントは.
  • Combine them into a relative clause: [友達にもらった] プレゼントは [2-1-3] (The present that I received from my friend [topic]).
• Phase 4 (Final Assembly & Star Extraction):
  • Full sentence: 誕生日に [2: 友達に] [1: もらった] [★ 3: プレゼントは] [4: とても] 嬉しかったです。
  • English Meaning: "I was very happy with the present I received from my friend on my birthday."
  • The Star (★) sits in the 3rd slot: Option 3 (プレゼントは).

Worked Example 2: Purpose Clause & Honorific Request

【Problem】
会議の _______  _______  ___★___  _______ お待ちください。

Options:
  1: こちらの
  2: 始まるまで
  3: 部屋で
  4: 準備が

Step-by-Step Deconstruction:

• Phase 1 (Periphery):
  • Opener: 会議の (Meeting's...)
  • Closer: お待ちください (Please wait). Demands a location particle で (e.g., 部屋でお待ちください) or a time boundary まで.
• Phase 2 (Collocation Pairs):
  • Opener 会議の attaches to a noun. Option 4 is 準備が. 会議の準備が (The preparation for the meeting...) forms [Opener-4].
  • Option 4 準備が (subject) naturally predicates with Option 2 始まるまで (until it begins): 会議の準備が始まるまで.
  • Option 1 こちらの (demonstrative modifier) must modify a noun. Option 3 is 部屋で. Together: こちらの部屋で (in this room) forms [1-3].
• Phase 3 (Connecting Clauses):
  • こちらの部屋で [1-3] connects directly to the final action お待ちください: こちらの部屋でお待ちください.
  • Temporal clause 会議の準備が始まるまで [4-2] sets the time condition.
• Phase 4 (Final Assembly & Star Extraction):
  • Full sentence: 会議の [4: 準備が] [2: 始まるまで] [★ 1: こちらの] [3: 部屋で] お待ちください。
  • English Meaning: "Please wait in this room until the preparations for the meeting begin."
  • The Star (★) sits in the 3rd slot: Option 1 (こちらの).

Worked Example 3: Capability Evolution & Habit Formation

【Problem】
日本語は _______  _______  ___★___  _______ なりました。

Options:
  1: 話せる
  2: 毎日
  3: 練習して
  4: ように

Step-by-Step Deconstruction:

• Phase 1 (Periphery):
  • Opener: 日本語は (As for Japanese...)
  • Closer: なりました (became / reached state). Combined with Option 4 ように, this forms the classic grammar formula 〜ようになる (to come to / reach the point of doing).
• Phase 2 (Collocation Pairs):
  • Option 1 話せる (potential form: can speak) attaches directly to Option 4 ように + なりました: 話せるようになりました forms [1-4-Closer].
  • Option 2 毎日 (adverb: everyday) modifies the action in Option 3 練習して (te-form: practicing): 毎日練習して forms [2-3].
• Phase 3 (Connecting Clauses):
  • The sequential te-form 練習して [2-3] leads into the acquired capability 話せるようになりました [1-4-Closer].
• Phase 4 (Final Assembly & Star Extraction):
  • Full sentence: 日本語は [2: 毎日] [3: 練習して] [★ 1: 話せる] [4: ように] なりました。
  • English Meaning: "As for Japanese, by practicing every day, I reached the point where I can speak."
  • The Star (★) sits in the 3rd slot: Option 1 (話せる).

│  CORRECT Bubble: Mark ① (The option number in the star slot)                │
│  FATAL ERROR:    Mark ③ (Accidentally bubbling the slot number itself!)     │
└─────────────────────────────────────────────────────────────────────────────┘

Tactical Rules for Mondai 2 Success:

1. Never Bubble "3" Automatically: The star is always physically in the 3rd slot. The question asks which option (1, 2, 3, or 4) belongs in that 3rd slot. In our Example 3, Option 1 was in Slot 3, so the answer is 1, NOT 3.
2. Verify Particle Valence: If you have an intransitive verb like 行く or 住む, do not attach を to it. Ensure particles like に, で, を, and と match their required verbs.
3. Watch Time Budget: Allocate strictly 60–90 seconds per question. If you are stuck after 1 minute, write down the 2-piece pairs on your exam paper, make an educated guess on the star position, and move on.
