Articles and determiners on the TOEFL iBT:
worked exercises

To choose a determiner on the TOEFL iBT, check whether the noun is countable in this usage and whether your reader can identify what you mean. This two-part check prevents you from translating French articles automatically. Two worked teaching exercises use campus situations; they are not official ETS questions.

How should you prepare a noun phrase before choosing its article?

ETS describes Build a Sentence as a task in which you construct a grammatical sentence. The noun phrase is part of that construction: its determiner accompanies the noun and any adjectives. Our method starts with the head noun. In “a detailed request for funding,” that noun is “request”; “detailed” does not change its type.

Next, ask what your reader already knows. Are you introducing a new request, referring back to one in the previous message, or talking about requests in general? These intentions lead to different phrasing. Checking the noun first and then its reference keeps you from choosing an article at random at the start of a sentence. General statements with plural count nouns or noncount nouns often use no article: “Requests take time” or “Information is useful.” This does not mean every use of “the” is specific: the definite article can also refer to an entire category, as in “The heart pumps blood.”

Why does “information” work differently from “request”?

The British Council classifies “information,” “advice,” and “equipment,” among others, as noncount nouns in their common uses. They are not made plural directly and do not follow “a/an.” Compare our phrases “two requests” and “some information.” The first counts individual items; the second refers to an amount of information.

To give a specific number, choose an appropriate unit: “two pieces of advice” or “three items of equipment.” You can also choose a count noun that matches your meaning, such as “tips” for practical advice. In an email, this precision lets you ask for exactly what is missing: a particular instruction, several pieces of equipment, or general information.

Reporting advice in standard English

Written by Upsilar

The marine biology tutor sent three practical tips about the poster layout. Which sentence correctly reports the help using the noun “advice”?

The solution, step by step

C: “some useful advice.”

The method in action

  1. “Advice” is noncount in this usage. “Some useful advice” reports the help correctly, although the phrase does not preserve the exact number of suggestions.
  2. A adds an incorrect plural ending. B uses “a” directly with this noun. D combines “many,” which counts individual items, with “advice.” To keep the number three, write “three pieces of advice” or keep “three practical tips.”

When can the reader identify what “the” refers to?

The British Council explains that “the” is used for a reference that the reader or listener can identify. An earlier mention helps: “We ordered a replacement battery. The battery arrived today.” Here, the definite article refers back to the battery that was ordered. Shared context can also be enough; an earlier mention is not always necessary.

In our message, “Please leave the signed form on my desk,” the form can be identified from the previous exchange or the situation. By contrast, “Please bring a form” introduces a form without specifying which one. As you read, look for this continuity: a small difference in the article can show whether the text refers back to a specific item or introduces another possibility.

Referring to the same item

Written by Upsilar

A student borrowed a portable recorder to interview volunteers at the campus greenhouse. She returned ___ recorder that afternoon. Complete the sentence to refer to the same recorder.

Choose an answer.

Choose an answer.

The solution, step by step

A: “the recorder,” referring to the recorder already mentioned.

The method in action

  1. The prompt explicitly asks you to refer to the same device. “The” lets the reader identify it from the first sentence.
  2. C would introduce a device without referring back to the specific one. B does not fit before the initial sound in “recorder.” D requires a plural noun and would no longer refer to the single device that was borrowed.

How can you avoid stacking words that fill the same slot?

Possessives and demonstratives can also identify a reference, as the British Council notes. “My proposal” indicates a relationship to the writer; “this proposal” points to the proposal in the context. In these ordinary phrases, do not put “the” before a possessive: write “my proposal,” not “the my proposal.”

Our review follows a short sequence: head noun, number, determiner, reference. In “these revised estimates,” the plural noun must agree with “these.” In “this revised estimate,” both are singular. Then check that your reader knows which estimates you are referring to. Grammatical accuracy and message clarity should be checked together.

The pitfall

Assuming every noun has a fixed category

A dictionary describes how a noun is used, not just a label that applies in every sentence. Our method focuses on the specific meanings you encounter in your work: do not generalize a learned construction to another meaning. “Equipment” and “advice” are useful reference points, but they do not tell you how every abstract noun works.

Keep the complete phrase and its situation in your notebook: “some advice about the poster,” followed by a personal request using the same pattern. When in doubt, check the dictionary usage instead of relying on the French plural. These exercises practice two local decisions; they do not cover every rule for English articles.

Key takeaways

  • Identify the head noun before choosing its determiner.
  • Count individual items with a count noun; quantify a noncount noun.
  • “The” assumes a reference the reader can identify.
  • Review number, determiner, and continuity of reference together.
