2020年中考英语：宾语从句的三大要素
宾语从句是一种名词性从句，它在复合句中作主句的宾语即作宾语的是一个句子。宾语从句主要注意三大要素：
一、引导词
1.that从句是陈述句时，引导词用that，它本身无词义，不充当成分，在口语中可省略，但在正式场合不可省。
2.if或whether从句是一般疑问句时用if或whether，含义是“是否”。if whether一般情况下可以互换，但在构成whether……or not句式时只能用whether。
3.连接代词，连接代词what、which、who、whose连接副词从句是特殊疑问句时用，连接副词when、where、how、why
二、宾语从句的语序
宾语从句的语序都用陈述句语序即正常的主谓语序。例如：
He says that Tom will miss a lot of lessons
She asked whether we should hold a sports meeting
Do you know what the popalation of Dalianis?
三、宾语从句的时态
1.主句是一般现在时，从句可根据需要选用任何时态。例如：
She says that she is good at Chinese.
He Says that he has been ill for three days.
I don’t know if she will come tomorrow.
2.主句是一般过程时，从句可根据需要用相应的过去某种时态。即一般过去时，过去将来时，过去完成时等。例如：
She asked me where I lived.
He said that she had been ill for six days.
He said that he would return soon.
3.当从句讲述的是客观事实或真理时，从句时态不受主句的影响，都用一般现在时。例如：
The teacher said “Light travels faster than sound”
She said that the earth is round
特例：Could you tell me ……委婉的语气，常按照一般现在时处理。
Could you tell me where the nearest park is?
真题回放：
例1 2008·北京—Do you know for shanghai last night?
——At 9：00
A、what time he leavesB、what time does he leave
C、what time he leftD、What time did he leave
解析：考查宾语从句的用法。对于宾语从句要注意三要素：语序陈述语序、时态主句是过去式，从句要用相应的过去式;主句是一般现在时，从句根据需要确定时态、引导词that, whether/if，特殊疑问词。B和D语序不正确;由last night可知A项时态错误。故选C。
