宾语从句在主句中充当宾语,通常放在动词之后,例如 believe, think, suggest, indicate, explain, demonstrate, assume, argue 等。在学术英语中,宾语从句常用于表达研究结论、作者观点或数据说明。宾语从句内部必须使用陈述语序,即“连接词 + 主语 + 谓语”,不能使用疑问语序。例如,应说 I do not know why this trend occurred,而不是 I do not know why did this trend occur。that 引导的宾语从句主要陈述事实或观点;whether 和 if 表示“是否”;wh- 连接词用于引导包含具体疑问信息的宾语从句。

许多人想知道人工智能是否会取代某些工作。

mention 是及物动词,后面可以直接接宾语或宾语从句,不需要加 about。可以说 talked about that issue,但不能说 mentioned about that。

PTE 高频应用
PTE Usage
宾语从句在 PTE Academic 中非常常见,尤其出现在 Summarize Written Text, Write Essay, Retell Lecture, Summarize Spoken Text 和 Answer Short Question 的答案组织中。考生需要用宾语从句准确转述文本或讲座信息,例如 The speaker explains that..., The passage suggests that..., The research indicates that...。在口语部分,宾语从句可以帮助考生避免句子过短,提高语法复杂度;在写作部分,它可以帮助表达因果、观点、发现和不确定性。需要注意的是,PTE 评分重视 grammatical range and accuracy,因此宾语从句应保持语序正确、连接词准确、时态一致。

AI 学习建议
AI Learning Tips
写作中如果需要表达观点,可以优先使用“I believe that...”“It can be argued that...”“The evidence suggests that...”等结构,比简单句更符合学术表达。
遇到 why, how, where, when 引导的宾语从句时,先检查语序是否为“连接词 + 主语 + 谓语”,不要使用疑问句倒装。
在 PTE Summarize Written Text 中,宾语从句适合用来整合原文核心信息,例如“The passage explains that...”或“The author suggests that...”。
