whether 引导主语、宾语、表语和同位语从句，表示"是否"，本身不充当从句成分。它与 if 的分工是真题常考点：whether 可以直接跟 or not、可以作介词宾语、可以站在句首，if 只能出现在动词后的宾语从句里。
英语六级真题里 whether 引导的从句共 150 处实例，覆盖 4 类从句；本页按从句类型分节，精选 36 句真题例句（出自 26 套真题卷，句长 9–60 词）。 每节先给该类型的实例计数与所属从句族入口，再逐句给出例句：高亮从句在原句中的位置，标注它在句中的功能与嵌套层级，附中文翻译、逐句解析与出处试卷； 点句卡末尾的「本句详情」可看结构树逐层拆解、成分与时态标注、考点讲解与真题高频词。
判断要点 从句表达"是否"二选一时优先想到 whether；出现在句首、介词后或紧跟 or not 的位置，只能是 whether 而不能换成 if。

这是否正确，如果正确，生态危机将在何时何地发生，很难精确确定——这就是为什么政府和金融机构才刚刚开始将此类风险纳入其经济计算中。
主语从句,由 "Whether" 引导,位于主句谓语 "is" 之前,直接充当主语。从句内含并列:"Whether this is right" 与 "where and when the ecological axe will fall" 通过 "and if so" 连接。"if so" 为条件插入语,"where and when" 为并列的连接副词引导的间接疑问。

很难说母亲节消费的增长是否超出了人们的预期，考虑到美国人口持续增长，但一个因素可能是成年子女的母亲在女性中所占的比例正在上升。
该从句由 if 引导，作为 it 形式主语结构中的真正主语（真主语后置）。if 在此表"是否"之意（= whether），从句内容"母亲节消费是否在上涨"是"hard to say"的对象。从句内部包含比较从句"more than one would expect"作修饰。

I thought Kevin Simler put it well when he wrote, "If a brain anticipates that it will be rewarded for adopting a particular belief, it's perfectly happy to do so, and doesn't much care where the reward comes from—whether it's pragmatic(实用主义的) (better outcomes resulting from better decisions), social (better treatment from one's peers), or some mix of the two."
我认为凯文·西姆勒在他的著作中说得很好：“如果大脑预期它会因采纳特定信念而得到奖励，它会非常乐意这样做，并且不太在乎奖励来自哪里——无论是实用主义的（更好的决策带来更好的结果）、社交方面的（来自同伴的更好对待），还是两者的某种混合。”
该 whether 分句在破折号后补充说明 "where the reward comes from" 所涉及的选择范围，可理解为 "doesn't care" 的进一步宾语内容：不在乎它究竟是实用层面的、社会层面的，还是二者混合的奖励来源。

该从句位于主句系动词“is”之后，整体说明“What is less clear”的具体内容，充当表语；“whether”引导一个“是否……”的名词性从句。
"The question is whether those kinds of experiences do so systematically across individuals and create exactly the same changes. And I think that is that huge leap of faith."

"whether this be...or..." 是由 "whether" 引出的同位语从句,与先行词 "sports records" 同指,解释说明体育纪录的具体内容。"this" 指代 "sports records","be" 使用虚拟式,从句内容完整,符合同位语从句特征(名词=从句内容)。

然而，对于观看电视这一“后仰式”媒介的人们是否渴望互动存在疑问。
whether 引导的同位语从句，紧跟抽象名词 "doubts" 并说明其具体内容。该从句内部成分完整：主语 "people watching television"（含现在分词短语后置定语），谓语 "crave"，宾语 "interaction"。whether 在从句中不充当任何成分，仅作连接词。插入语 "a 'lean back' medium" 对 television 作同位说明。从句与 doubts 可用 be 连接验证同位关系：the doubts = whether people crave interaction。

When you hear people speaking of making a rapid transition toward any type of energy, whether it is a switch from coal to nuclear power, or a switch from gasoline-powered cars to electric cars, or even a switch from an incandescent to a fluorescent light, understanding energy system inertia and momentum can help you decide whether their plans are feasible.
当你听到人们谈论向任何一种能源快速转型时，无论是从煤炭到核能的转换，还是从汽油动力汽车到电动汽车的转换，甚至是白炽灯到荧光灯的转换，理解能源系统的惯性和动量可以帮助你决定他们的计划是否可行。
