2026年阳光课堂金牌练习册九年级英语全一册人教版第34页答案
【例】将下面两个句子合并为一个包含宾语从句的复合句
Is she your new English teacher? I want to know.
I want to know
whether
she
is
your new English teacher or not.
【答案】whether;is

答案

1. whether 2. is

解析

【分析】要将两个简单句合并为含宾语从句的复合句,需分两步:1. 确定宾语从句的连接词,当宾语从句后带有or not时,连接词需用whether;2. 确定从句的谓语动词,主句为一般现在时,从句主语是she,be动词需用is。
【解析】原句是一般疑问句“Is she your new English teacher?”,合并为宾语从句时,因从句后有or not,连接词选用whether;主句“I want to know”是一般现在时,从句主语为she,be动词用is,因此依次填入whether、is。
【答案】whether;is
【知识点】宾语从句;whether的用法
【点评】本题考查宾语从句的连接词及be动词的基础用法,需掌握whether与or not的搭配规则,属于英语基础题型。

一、用that、if或whether填空
1. I wonder
whether
or not they have arrived safely.
2. He told me
that
he was feeling sick.
3. The scientist doesn't know
whether/if
the experiment has been successful.
4. We are not sure
whether/if
it will rain tomorrow.
5. Can you tell me
whether/if
the train has left?

答案

1. whether 2. that 3. whether/if
4. whether/if 5. whether/if

解析

【分析】首先明确that、if、whether作为宾语从句引导词的用法规则:①that引导宾语从句时无实际意义,在从句中不充当成分,用于陈述事实的语境;②if和whether引导宾语从句时意为“是否”,多数情况可互换,但whether常与or not连用,if一般不与or not直接搭配,需根据句子结构和语境判断。
【解析】1. 句中出现or not,是whether的典型使用场景,故填whether;2. 从句陈述“他感觉不舒服”的事实,用that引导无实际意义的宾语从句;3. 表不确定实验是否成功,无or not,故whether和if均可;4. 表不确定是否下雨,无or not,故whether和if均可;5. 询问火车是否离开,无or not,故whether和if均可。
【答案】1. whether 2. that 3. whether/if 4. whether/if 5. whether/if
【知识点】宾语从句引导词辨析
【点评】本题考查宾语从句中that、if、whether的用法差异,核心是掌握whether与if在“是否”含义下的使用规则,尤其是与or not连用时只能用whether的特殊情况,属于基础语法考点,需牢记引导词的不同适用场景。
