One of the most challenging parts of TOEFL Build a Sentence questions is determining where adverbs belong. Many students understand the grammar of a sentence but still struggle to reconstruct the exact sentence ETS intends. This often happens because adverbs can move around a sentence, and multiple grammatical versions may be possible.
In the new TOEFL Writing section, students need to work quickly. Understanding adverb placement can save valuable time and improve accuracy.
In this lesson, you'll learn:
- What adverbs are
- What adverbs modify
- Why adverbs move around sentences
- How prompts and fixed words influence adverb placement
- Common TOEFL Build a Sentence adverbs
- Practice exercises with answers
By the end of this lesson, you'll have a much stronger understanding of adverb placement in TOEFL Build a Sentence questions.
What Is TOEFL Build a Sentence?
The new TOEFL Writing section contains three tasks:
Task 1: Build a Sentence
Students unscramble words to create complete sentences.
Task 2: Write an Email
Students write a professional email based on a situation.
Task 3: Writing for an Academic Discussion
Students respond to a discussion question posted by a professor and classmates.
Of these three tasks, TOEFL Build a Sentence is often the most grammar-focused. Success requires recognizing sentence patterns quickly and accurately.

Adverbs in Questions
An adverb describes:
- A verb
- An adjective
- Another adverb
- An entire sentence
Examples:
The professor explained the assignment clearly.
How was the assignment explained?
Clearly.
Students must carefully complete the writing task.
How should students complete the task?
Carefully.
In many TOEFL Build a Sentence questions, the biggest challenge is identifying exactly what the adverb modifies.
The Most Important TOEFL Build a Sentence Question
Whenever you see an adverb, ask:
What is this adverb modifying?
Consider:
The professor explained the grading criteria clearly.
The adverb clearly modifies:
explained
not
grading criteria
Understanding this relationship often reveals where the adverb belongs.
Common Adverbs in TOEFL Build a Sentence
Students frequently encounter these adverbs:
Clearly
The professor explained the instructions clearly.
Carefully
Students should carefully review the directions.
Successfully
The team successfully completed the project.
Online
Students may submit assignments online.
Currently
The library is currently closed.
These five words appear often because they modify actions and create opportunities for word-order questions.
TOEFL Build a Sentence and Flexible Adverb Placement
One reason TOEFL Build a Sentence questions are difficult is that English often allows adverbs to appear in more than one position.
Consider:
Position 1
Clearly, the professor explained the grading criteria.
Position 2
The professor clearly explained the grading criteria.
Position 3
The professor explained the grading criteria clearly.
All three sentences are grammatical.
This flexibility is one reason students sometimes feel confused during the exam.
Why Context Matters in TOEFL Build a Sentence
Many students focus only on the scrambled words.
However, ETS typically provides:
- A prompt
- One or more fixed words
- Punctuation
- A sentence frame
These clues help determine the intended answer.
Example
Prompt:
The professor made the project requirements easy to understand.
Sentence Frame:
The professor has explained _____ .
Scrambled Words:
clearly
expectations
final
for
project
the
the
The prompt strongly suggests that clearly modifies explained.
Without the prompt, several grammatical possibilities might exist.
With the prompt, the intended meaning becomes much easier to identify.
TOEFL Build a Sentence Fixed Words and Adverb Placement
One of the most overlooked clues in TOEFL Build a Sentence questions is the fixed word or phrase already provided.
Example 1
Prompt:
Maria missed class and needed notes.
Sentence Frame:
_____ because _____ .
The word because signals a cause-and-effect relationship.
Example 2
Prompt:
The team changed its schedule.
Sentence Frame:
_____ after _____ .
The word after signals a time sequence.
Example 3
Prompt:
Students must submit homework using the course website.
Sentence Frame:
Can _____ now?
The word now helps determine where time-related adverbs belong.
Fixed words often reveal the intended sentence structure.
Understanding Online: Adjective or Adverb?
Suggested Image Alt Text: TOEFL Build a Sentence online adverb versus adjective
Consider these two sentences:
Sentence A
Students can submit their assignments online.
Sentence B
Students can submit their online assignments.
Both are grammatical.
However, they have different meanings.
Sentence A
Online = adverb
How do students submit?
Online.
Sentence B
Online = adjective
What kind of assignments?
Online assignments.
This is exactly the type of distinction ETS may test.
Understanding Carefully
Consider these examples:
Natural
Students must carefully complete the writing task within the time limit.
Less Natural
Students must complete the writing task within the time limit carefully.
Why?
Because carefully modifies complete the writing task.
The adverb generally sounds more natural closer to the action.
Understanding Successfully
Example 1
The team successfully completed the project.
Example 2
The team completed the project successfully.
Both are common.
This means students must pay attention to the prompt and fixed words when solving TOEFL Build a Sentence questions.

Step 1

Step 2
Identify the main action.
Step 3

Step 4

Step 5

This strategy dramatically improves accuracy.

What is this adverb modifying?
That simple question will help you solve many TOEFL Build a Sentence questions correctly and more confidently.
