第二部分 Grammar 宾语从句（1）
【知识梳理1】宾语从句的核心概念
名词、代词、动词的- ing 形式或 t d 形式都可以作宾语，例如 buy a bk, help him, stp ding sth, want t d sth等。这些例子中的宾语是用一个单词或短语来表达的。
但是，当要用英语表达 “我知道你昨天去看电影了” 时，我们就无法在knw后用一个单词表达出 “你昨天去看电影了” 这个意思。“你昨天去看电影了” 结构中包含行为本身、行为的执行者和行为的承受者，是一个完整的句子，因此只能用句子表达。这种放在动词后面作宾语的句子，我们称为 “宾语从句”。
结构：主句 + 连接词 + 从句
例：I think that yu are right.主句 连接词 从句（作宾语）
语序：必须用陈述句语序！（主语在前，谓语在后）
❌：I dn’t knw where is he.
✅：I dn’t knw where he is.
❌：He asks are yu a student.
✅：He asks if yu are a student.
时态（最重要）
1）主句是一般现在时，从句时态不受影响，该用什么用什么。
例：He says he will cme tmrrw.He says he is reading.
2）主句是一般过去时，从句必须用过去的某种时态。
例：He said he was busy.He said he wuld cme.
3）从句是客观真理、事实，永远用一般现在时，不受主句影响。
例：The teacher said the earth is rund.
【即时练习】
I think ______ he is right.
A. that B. if C. whether
He asked ______ I was late.
A. that B. if C. what
The teacher said the sun ______ bigger than the earth.
A. is B. was C. will be
【知识梳理2】that引导的宾语从句
当谓语动词表示肯定的概念，如 “希望”“相信”“知道” 或 “说” 时，其后面的句子一般用 that 引导。that 没有任何词汇意义，只具有语法功能，目的是使读者清楚后面的句子是作前面动词的宾语，多数情况下 that 可以省略。
例如：I hpe (that) it will snw this winter.
我希望今年冬天会下雪。
I believe (that) we shall becme gd friends.
我相信我们会成为好朋友。
Betty thinks (that) trees can imprve the air.
Betty认为树木可以改善空气质量。
注意：并非所有的动词后面都可接 that 引导的宾语从句。常接 that 引导的宾语从句的谓语动词有：believe, expect, explain, feel, hear, hpe, imagine, prefer, prmise, reprt, say, see, tell, think, understand, warn, wish 等。
【即时练习】
He is a gd student. I believe. （改写句子）
___________________________________________
The sun rises in the east. Our teacher tld us. （改写句子）
___________________________________________
【知识梳理3】whether/if引导的宾语从句
如果我们要表达 “他不知道他们周六是否会去植树” 或 “我记不清以前是否见过他” 这样的不确定的概念时，从句就要用 whether 或 if 来引导，不能用 that。
例如：He des nt knw whether they will plant trees n Saturday r nt.
他不知道他们周六是否会去植树。
He asks whether /if we will g fishing n Sunday.
他问我们星期天是否会去钓鱼。
Tm wants t knw whether /if he needs t cme early tmrrw.
Tm想知道他明天是否需要早来。
⚠注意：在宾语从句中没有r nt的情况下，一般来说两个词都可以用。
I dn’t knw if he will cme.
I dn’t knw whether he will cme.
如果从句中有r nt的话，一般就要选择whether，构成whether… r nt的结构。
✅ I dn’t knw whether he will cme r nt.
❌ I dn’t knw if…r nt.
其他必须用whether的情况：
介词后面的宾语从句：I am interested in whether he will cme.
与不定式连用：I dn’t knw whether t g r stay.
【即时练习】
I dn’t knw ______ he will cme tmrrw.
A. that B. whether C. what
He wants t knw ______ we can g with him r nt.
if B. whether C. when
