WFD 的核心不是创造句子，而是在短时间内准确还原听到的句子。考生需要通过语法框架预测句子走向。例如，听到 The lecture was 时，应立即判断后面可能接 passive participle、adjective complement 或 prepositional phrase；听到 There are several 时，应预判复数名词；听到 Students should 时，应使用动词原形。中国考生常因忽略冠词、复数、介词和被动语态而失分，因此必须把语法结构、词汇搭配和声音信号结合起来记忆。
The results of the experiment were published in a scientific journal.
实验结果发表在一本科学期刊上。
There are several important factors affecting climate change.
有几个重要因素正在影响气候变化。
Students should submit their assignments before the deadline.

名词短语作主语
WFD 中经常以较长的 noun phrase 开头，例如 The impact of technology、The development of new policies、A significant number of students。听到开头后，要快速判断中心名词的单复数，并决定后面的动词形式。
The impact of social media on communication is widely debated.
社交媒体对交流的影响被广泛讨论。
A significant number of students have difficulty managing their time.
相当多的学生在时间管理方面有困难。
被动语态结构
PTE WFD 高频使用 passive voice，因为学术英语强调研究、结果、政策和过程，而不是动作执行者。听到 was、were、is、are、has been、have been 时，要预判过去分词。
The final report was submitted to the department yesterday.
最终报告昨天已提交给该部门。
New regulations have been introduced to improve public safety.
新的规定已经被引入，以提升公共安全。
There be 句型
There be 结构常用于引出某种现象、数量、问题或证据。考生要注意 be 动词与后面真正主语的一致关系，例如 There is evidence 和 There are several reasons。
There is strong evidence to support this argument.
有强有力的证据支持这一论点。
There are many opportunities for students to develop practical skills.
学生有很多机会发展实践技能。
介词短语作修饰语
WFD 句子常在句末加入 prepositional phrases，例如 in the library、for further research、on campus、during the semester。介词通常弱读，容易被中国考生漏写。
The books are available in the main library.
这些书可以在主图书馆找到。
The data will be used for further research.
这些数据将被用于进一步研究。
情态动词加动词原形
WFD 中常见 should、must、can、could、may、might、will、would。情态动词后必须接 base verb，不加 to，不加第三人称单数。
Researchers should consider the limitations of the study.
研究人员应该考虑该研究的局限性。
Students can access the online materials through the university website.
