Achieving a high score on the TOEIC test, especially in Parts 5 and 6, depends not only on a rich vocabulary but also on a deep understanding of grammar. The 2024 TOEIC test is increasingly featuring sophisticated and complex grammatical structures that can easily confuse test-takers. Mastering these difficult grammar points not only helps you avoid common traps but also increases your completion speed, allowing more time for challenging questions. This article will delve into detailed explanations of the most difficult grammar questions, equipping you with solid knowledge to confidently enter the exam room.

How to differentiate between Relative Clauses and Noun Clauses?

This is one of the most confusing grammar points for candidates. Both can begin with words like that, what, which, who,... However, their functions in a sentence are completely different.

1. Relative Clause:

• Function: To modify the noun that comes directly before it. It acts like an adjective, providing more information about that noun.
• Identification: Always follows a noun or pronoun. If the relative clause is removed, the main sentence still makes sense, merely losing supplementary information.
• TOEIC Example: The candidate who has the most experience in marketing will be offered the position.
  Analysis: The clause "who has the most experience in marketing" modifies the noun "The candidate". It specifies "which candidate" will get the position.

2. Noun Clause:

• Function: Acts as a noun in the sentence. It can be a subject, an object of a verb, or an object of a preposition.
• Identification: It does not modify any noun. It is itself a main component of the sentence (subject/object). If the noun clause is removed, the sentence becomes grammatically incomplete.
• TOEIC Example: The manager will decide who has the most experience in marketing.
  Analysis: Here, the clause "who has the most experience in marketing" is the object of the verb "decide". It answers the question "What will the manager decide?".

When to use To-V and when to use V-ing in a TOEIC sentence?

The choice between a to-infinitive and a gerund depends on the main verb preceding it. This is a common trap in Part 5.

• Verbs followed by To-V: Often express a purpose, a plan, or a future-oriented action. Common verbs: want, hope, decide, plan, agree, refuse, promise, manage, afford, learn...
  Example: We plan to launch the new product line next quarter.
• Verbs followed by V-ing: Often describe an action that has happened, is happening, or is a habit/preference. Common verbs: enjoy, avoid, suggest, recommend, finish, keep, mind, practice, quit...
  Example: The team suggested postponing the meeting until Friday.
• Special Cases (change in meaning): Some verbs like remember, forget, stop, try, regret can be followed by both, but with different meanings.
  - stop to do something: pause to do another action. (He stopped to check his email.)
  - stop doing something: cease the action itself. (He stopped checking his email.)

What advanced conditional sentences often appear in the TOEIC test?

Beyond the three basic conditional types, the TOEIC test often assesses knowledge of mixed conditionals and inversion in conditionals to challenge candidates.

1. Mixed Conditionals:

• Type 3-2 (past condition, present result): The 'If' clause uses Type 3, and the main clause uses Type 2.
  Example: If I had taken your advice, I would be in a better position now.
• Type 2-3 (present condition, past result): The 'If' clause uses Type 2, and the main clause uses Type 3.
  Example: If he were more diligent, he would have passed the exam.

2. Inversion in Conditionals:

• Type 1: Use 'Should' instead of 'If'. Should + S + V(base form)...
  Example: Should you need any further assistance, please do not hesitate to contact us. (instead of If you should need...)
• Type 2: Use 'Were' instead of 'If'. Were + S + (to V)...
  Example: Were I in your position, I would reconsider the offer. (instead of If I were...)
• Type 3: Use 'Had' instead of 'If'. Had + S + P2...
  Example: Had the company invested in new technology, its productivity would have increased. (instead of If the company had invested...)

How to identify and handle questions about complex Conjunctions and Prepositions?

Questions about conjunctions and prepositions require candidates to clearly understand the grammatical structure that follows them. This is the key to differentiating and choosing the correct answer.

• Concession Group:
  - Although / Though / Even though + Clause (S + V):
  Example: Although the traffic was heavy, we arrived on time.
  - Despite / In spite of + Noun Phrase / V-ing:
  Example: Despite the heavy traffic, we arrived on time.
• Reason Group:
  - Because / Since / As + Clause (S + V):
  Example: The event was cancelled because it rained heavily.
  - Because of / Due to / Owing to + Noun Phrase / V-ing:
  Example: The event was cancelled due to the heavy rain.

When taking the test, immediately look at the component after the blank. If it is a complete clause (with a subject and a verb), choose a conjunction. If it is a noun phrase or a gerund, choose a preposition. Referring to sets of TOEIC 2024 test solutions will help you get familiar with this type of question.

How are Participles and reduced Relative Clauses used?

Reducing a relative clause with a participle is an advanced grammar technique that frequently appears in TOEIC Parts 5 and 6. It makes the sentence more concise and formal.

• Using the Present Participle (V-ing): When the relative clause is in the active voice.
  Original: The woman who is sitting next to the CEO is our new project manager.
  Reduced: The woman sitting next to the CEO is our new project manager.
• Using the Past Participle (V-ed/P2): When the relative clause is in the passive voice.
  Original: The report which was submitted by the marketing team is very impressive.
  Reduced: The report submitted by the marketing team is very impressive.

Tip: To choose correctly between V-ing and V-ed, determine if the noun it modifies is the agent performing the action (active -> V-ing) or the receiver of the action (passive -> V-ed).

What are the most common grammar traps with the Passive Voice?

The passive voice is more than just `be + P2`. The TOEIC test often uses more complex passive structures to assess a candidate's comprehension.

• Passive with Reporting Verbs: Verbs like say, think, believe, report, consider are often used in special passive forms.
  Example: It is reported that the merger will be finalized next month. OR The merger is reported to be finalized next month.
• Causative Passive: The structure have/get something done, which means to arrange for someone to do something for you.
  Example: Mr. Jones had his computer repaired yesterday.
  This is a very confusing structure; candidates need to be careful to distinguish it from the active causative (have someone do something).

Mastering these grammar points is a crucial part of your English test preparation to achieve your target TOEIC score. Instead of memorizing rules, try to understand the nature of the structures and practice them regularly through exercises and mock tests.

Conclusion

TOEIC grammar can be complex, but it is not unconquerable. By focusing on a deep understanding of difficult structures like relative clauses, participles, advanced conditionals, and special passive forms, you will build a solid foundation. Remember, regular practice and analyzing your mistakes are the keys to turning knowledge into true test-taking skill. Good luck on your journey to conquering your dream TOEIC score!
