TOEFL iBT Reading “Complete the Words”: 품사를 보고 빠진 철자 채우기

TOEFL iBT의 “Complete the Words” 과제에서는 몇몇 단어의 끝 철자가 빠진 짧은 문단을 읽고 빠진 철자를 채웁니다. 세 가지 확인으로 맞는 단어에 도달할 수 있습니다. 인쇄된 철자를 모두 그대로 두고, 그 단어가 문장에서 하는 역할(명사, 동사, 형용사, 부사)을 정하고, 완성한 문장을 다시 읽는 것입니다. 이 글은 2026년에 도입된 TOEFL iBT 형식을 기준으로 하며, 중급(B1) 이상의 영어 실력을 갖춘 학습자를 위해 썼습니다.

Two adult learners discuss a reading task at a community study table.

A college team prepares old chairs for a community classroom. The chairs are damaged, but their wooden frames can be repaired. Volunteers follow an instruction card and work carefully, checking each joint before they paint it. A supervisor explains how to use the workshop safely. Some reusable materials come from earlier projects, while broken parts need a replacement. The team records what it has done so that a future group can understand the process and continue the work confidently.

A student club holds a repair event where neighbours bring items that no longer work properly. Before the event, volunteers arrange the tables by activity and place clear signs near the entrance. Each visitor describes the problem to a student, who writes a short note. A trained helper examines the item and explains whether it can be repaired safely.

Check a rebuilt word three ways

A language café uses a calendar to coordinate its evening groups. One group discusses books, while another practises conversation about travel. The coordinator posts an update whenever a meeting moves to a different room. Members read the whole notice because the first sentence may explain the change and the final sentence may give a reason. A familiar word can still have the wrong form in a particular sentence. Good readers check the surviving letters, the surrounding grammar and the meaning of the whole message.

How do you check a word you have rebuilt?

Check the letters first, then the grammar, and then the meaning of the whole sentence.

The examples on this page are teaching models. Later pages use different texts.

Three checks on a possible answer

Check the letters: coordina___ → coordinator. The surviving prefix stays unchanged; add tor.
Check the grammar: one group discu____ books → discusses. A singular group takes the finite verb discusses.
Check the meaning: a meeting moves to a diff_____ room → different. The new room is not the same room; add erent.

Read again after reconstruction

Use the intact final sentence to confirm what the paragraph is trying to say.
Read every restored word inside its full sentence.
Mark the cue that settled a difficult choice, not only whether your answer was right.

The campus library has introduced a booking service for quiet study rooms. Students can reserve a room through the library website by choosing a date and a starting time.

Students who no longer need a room should cancel the booking so someone else can use it. During busy weeks, staff may limit how many bookings one student can make. These rules keep the system fair and make shared spaces more accessible to everyone.

어떻게 배우고 싶나요?

계정이 있나요?

무료 계정은 한 단원을 계속 열어 둘 수 있습니다.

과제는 어떤 모습인가요?

몇몇 단어가 일부만 인쇄된 짧은 문단이 나옵니다. 앞부분은 있고 나머지가 빠져 있습니다. 문단이 올바르게 읽히도록 각 단어를 완성하는 것이 과제이며, 대개 인쇄된 철자와 문장 모두에 맞는 답은 하나뿐입니다.

여기 연습 예시에서는 밑줄 하나가 철자 하나를 뜻하므로, 빈칸을 보면 어미의 길이도 알 수 있습니다. 낡은 의자를 고치는 자원봉사자에 관한 문단에서 가져온 풀이 예시 세 가지입니다.

“Volunteers work care_____.” → carefully: 다섯 글자 “fully”가 부사를 만듭니다. 문장이 어떻게 일하는지를 말하기 때문입니다.
“The chairs are dam____.” → damaged: 네 글자 “aged”가 의자의 상태를 나타냅니다.
“The card gives an instruc____.” → instruction: 네 글자 “tion”이 “an” 뒤의 명사를 완성합니다.

빈칸마다 하는 확인

주제를 알면 답에 가까워지지만, 형태를 정하는 것은 문장입니다. 문단 전체를 뜻 위주로 한 번 읽은 뒤 빈칸마다 확인하세요.

인쇄된 철자 지키기: 답은 그 철자에 덧붙는 것이지 대신하는 것이 아닙니다.
단어의 역할 정하기: “a”, “the”나 형용사 뒤에는 명사, “can”, “should”, “to” 뒤에는 동사원형, 명사 앞이나 “is” 뒤에는 형용사, 어떻게 일어나는지를 말하면 부사입니다.
빈칸 수 세기: 뜻은 맞아도 길이가 틀리면 틀린 단어입니다.
완성한 문장 읽기: 어색하게 들리면 어미를 다시 확인하세요.

직접 해 보기: “work___”를 완성하는 어미는?

짧은 질문과 답을 듣고, 거기서 말하는 확인을 같은 문단의 다른 문장에 적용해 보세요. 가능한 어미는 세 개지만 맞는 것은 하나뿐입니다.

“Several work___ prepare chairs for painting.”

Question How do you choose the right form of a word?

Answer Look at the job the word does in its sentence: noun, verb, adjective or adverb.

“Several work___”를 완성하는 어미는 무엇인가요?

알아 두면 좋은 어미

많은 빈칸에는 품사를 바꾸는 어미가 숨어 있습니다. 어미는 단어 하나가 아니라 문장과 함께 익히세요.

-ly는 형용사를 부사로 바꿉니다: careful → carefully, safe → safely.
-tion과 -ment는 명사를 만듭니다: instruct → instruction, replace → replacement.
-ed는 흔히 상태를 나타냅니다: damage → damaged.
-able은 형용사를 만듭니다: reuse → reusable (“Reusable materials can be used again.”).
-er는 어떤 일을 하는 사람을 나타냅니다: work → worker, “several” 뒤에서는 workers.
복수형과 동사의 -s: “each worker”지만 “several workers”, “a helper checks”지만 “helpers check”.

연습 방법

하루에 문단 하나면 습관을 만들기에 충분합니다. 이 루틴은 약 15분 걸립니다.

읽기: 쓰지 말고 문단 전체를 한 번 읽습니다.
채우기: 빠진 철자만 씁니다. 어려운 빈칸은 건너뛰고 나중에 돌아옵니다.
확인: 답을 보기 전에 완성한 문장을 모두 다시 읽습니다.
설명: 답 두 개에 대해 결정을 내린 단서를 적습니다. 철자 패턴, 문법 규칙, 뜻 중 무엇이었나요?
모으기: 틀린 어미를 단어 가족 목록에 추가합니다. 예: care, careful, carefully, careless.

흔한 실수

놓치는 답의 상당수는 모르는 단어가 아니라 형태 때문입니다. 한국어는 ‘의자 두 개’처럼 수량 뒤에서도 명사에 복수 표시를 꼭 붙이지 않고 관사도 없어서, “two chair”나 “several worker” 같은 실수가 나오기 쉽습니다. “several”, “two”, “a” 뒤의 명사는 모두 확인하세요.

단어 전체를 쓰거나 인쇄된 철자를 바꾸는 것.
주제에는 맞지만 문법에는 맞지 않는 단어를 고르는 것: 문장에 “carefully”가 필요한데 “careful”.
“several”, “many”, “two” 뒤에서 복수형을 잊는 것.
빈칸 수를 무시하는 것.
어미 철자를 틀리는 것: “carefuly”, “instrucsion”.

다음 단계

연습 문단을 완성하고 답 두 개를 설명할 수 있게 되면, 공지와 메시지, 더 긴 지문을 읽으며 세부 정보를 결합하는 과제로 넘어가세요. 쓰기 섹션의 문장 만들기도 같은 품사 확인을 씁니다.

자주 묻는 질문

TOEFL iBT의 “Complete the Words”는 무엇인가요?

2026년에 도입된 TOEFL iBT 형식의 Reading 과제입니다. 짧은 문단에서 몇몇 단어의 빠진 끝 철자를 채워 문단이 올바르게 읽히도록 합니다.

단어 전체를 쓰나요, 빠진 철자만 쓰나요?

빠진 철자만 씁니다. 인쇄된 앞부분은 그대로 두고, 여러분이 쓴 철자가 단어를 완성합니다.

TOEFL “Complete the Words” 실력을 어떻게 높일 수 있나요?

매일 짧은 문단 하나로 연습하고, 완성한 문장을 모두 다시 읽고, 답 두 개의 단서를 적으세요. 단어를 하나씩 외우기보다 care, careful, carefully 같은 단어 가족으로 익히세요.

TOEFL iBT Reading 연습에는 어느 정도 수준이 필요한가요?

중급(B1) 정도부터 연습 효과가 가장 좋습니다. 그보다 낮으면 문단의 단어 대부분이 새로워서 과제가 추측이 되어 버리므로, 먼저 어휘를 쌓으세요.
