Format at a glance

You see a short instruction or target meaning plus several word/phrase fragments. Every fragment must be used exactly once to form a complete, grammatical sentence. Items are computer-scored quickly; there is no essay-style rater commentary. Two five-item blocks appear in the ~23-minute writing section alongside Write an Email and Academic Discussion.

What this is

“造句”是2026年TOEFL iBT独有的语法导向写作任务，你需要将打乱的片段重新排列成一个正确的句子或疑问句。每单元包含五个项目，完整写作部分包括两个单元，共十个评分造句，之后是写邮件和学术讨论任务。成功关键在于语法控制——词序、主谓一致和标点，而非创造新观点。掌握格式后，切换到EnglishTestNow上的限时TOEFL iBT造句练习，让节奏变得自然而然。每次练习后，检查是否完成了该任务所需的步骤——不仅仅是整体部分的估计。当同样的错误重复出现两次时，打开本站的相关写作指南，比较相关任务的评分标准，然后再预约完整模拟考试。

为什么本部分很重要

你会看到简短的指令或目标含义，以及若干词语/短语片段。每个片段必须且只能使用一次，组成完整且语法正确的句子。项目由计算机快速评分，无作文式评分员评论。两个五题单元出现在约23分钟的写作部分，与写邮件和学术讨论任务并列。句子语法完整，符合预期含义，子句顺序正确，主谓一致，冠词和结尾标点准确。片段必须连贯拼接，不得增删词汇。若提示要求疑问句，需包含适当的倒装或助动词。考生通常在练习TOEFL iBT造句时，如果只做通用语言训练而非官方计时下的答题模式，表现会较差。

常见错误及避免方法

Practicing Build a Sentence only with untimed or open-book drills until the final week before TOEFL iBT.
Memorizing model answers that collapse when the Build a Sentence prompt uses an unfamiliar theme or integrated input.
忽视片段附带的标点，改变句意或语法。
Treating Writing as one skill without drilling Build a Sentence as its own high-frequency exam move.

Tips that move the score

Map the official TOEFL iBT instructions for Build a Sentence before you practice: timing, response length, and any integrated input you must use.
Record one untimed attempt to learn the shape of Build a Sentence, then switch immediately to exam-realistic timing so pacing becomes automatic.
Review every practice attempt by error type—vocabulary gaps, structure, fluency, or missed instructions—rather than only checking a final score estimate.
Build a short checklist unique to Build a Sentence (opening move, evidence moves, closing move) and reuse it until it is automatic under pressure.
Alternate focused Build a Sentence drills with full writing mocks so you can transfer improvements without losing stamina.
When two mocks in a row stay at your target for this task, raise difficulty by shortening prep time or increasing response complexity instead of repeating easy prompts.

What is TOEFL iBT Build a Sentence?

TOEFL iBT Build a Sentence is a scored task (or resource guide) inside the Writing section. Official forms expect a response that follows the published instructions, timing, and evaluation criteria for this format. EnglishTestNow practice mirrors those constraints so you can rehearse the same decisions you will make on test day.

How should I practice TOEFL iBT Build a Sentence?

Start with format familiarization, then move to timed attempts. Log mistakes by type, drill the weakest pattern, and re-test under full timing. Mix single-task drills with complete writing practice so stamina and task switching stay sharp.

What do examiners look for in TOEFL iBT Build a Sentence?

Markers focus on whether you completed the task, organized clearly, used appropriate language range, and met any integrated or length requirements. Scoring sheets differ by exam brand, but ignoring instructions or going off-topic almost always costs more than a few grammar slips.

How does Build a Sentence affect my overall TOEFL iBT score?

Writing performance is aggregated into your official result. Weakness on a frequent task like Build a Sentence can drag an entire section below visa or university minimums even when other tasks feel comfortable. Train the bottleneck deliberately rather than averaging practice time evenly.
