宾语从句(一)
- 定义:在复合句中,由一个句子充当宾语,这个句子叫作宾语从句。
- 关联词
- that:当宾语从句由陈述句变化而来时,由that来引导从句,其中的that无具体意义,常在口语中省略。例如:My mum told me (that) she used to be thin.
- if和whether:当宾语从句由一般疑问句变化而来时,用if或whether来引导从句,意为“
是否
”。从句部分用陈述语序。例如:I ask Sally if/whether she slept well last night.
- 只用whether而不用if的情况
- 其后紧跟or not时。例如:I don’t know whether or not he lied.(图1)
- 当宾语从句位于句首表示强调时。例如:
Whether
he lied,I am not sure.
- 宾语从句作介词的宾语时。例如:It depends on whether she is available.
- 句子中有if引导的条件状语从句时。例如:He asked me whether I would move to New York if I got the job.
- 在动词不定式之前。例如:I don’t know whether to go there at once.

答案

是否;Whether

解析

【分析】本题考查宾语从句中if与whether的用法,需明确两个核心规则:一是由一般疑问句转化而来的宾语从句中,if/whether的含义;二是宾语从句位于句首强调时的引导词选择,据此完成填空。
【解析】1. 当宾语从句由一般疑问句变化而来时,if或whether表示“是否”,对应第一个空填“是否”;2. 当宾语从句位于句首表示强调时,只能用whether引导,对应第二个空填Whether。
【答案】是否;Whether
【知识点】宾语从句、if与whether的用法
【点评】本题为英语语法基础题,聚焦宾语从句中if和whether的核心用法,需准确记忆相关规则,难度较低。
【难度系数】0.8

答案

解析

【分析】
本题考查宾语从句中that、if、whether的用法区别,需结合句子语境(如是否与or not连用、是否为介词后从句、从句类型等)选择合适的引导词:①whether常与or not直接搭配,介词后接宾语从句只能用whether;②陈述类宾语从句(如believe、remember后接的肯定陈述)常用that;③表示“是否”的疑问类宾语从句,ask等动词后可接if或whether。
【解析】
1. 句中出现or not,只能用whether,构成whether...or not的固定搭配,表“是否”;
2. believe后接陈述类宾语从句,用that引导,that在从句中无实义,仅起连接作用;
3. asked后接疑问类宾语从句,表“是否”,if和whether均可使用;
4. 从句位于介词about之后,介词后接宾语从句只能用whether,不能用if;
5. remembered后接陈述类宾语从句,用that引导,连接陈述内容。
【答案】
1. whether 2. that 3. if/whether 4. whether 5. that
【知识点】
宾语从句引导词(that、if、whether的用法)
【点评】
本题聚焦宾语从句引导词的基础用法,需掌握不同语境下that、if、whether的使用规则,属于英语语法中的基础考点,只要理清搭配和语境即可正确作答。
【难度系数】
0.5
Ⅱ. 按要求完成句子。
1. My teacher told us, “18th May is International Museum Day.”(改为宾语从句)
My teacher told us that
18th May

is International Museum Day
.
2. Susan said,“I will give a report at the meeting.”(改为宾语从句)
Susan said
(that)

she would give a report
at the meeting.
3. “Do you have a good time at the amusement park?” he asked me.(改为宾语从句)
He asked me
if/whether I had
a good time at the amusement park.

答案

1. 18th May is International Museum Day
2. (that) she would give a report
3. if/whether I had

解析

【分析】
把直接引语转换为宾语从句时,需遵循三个核心规则:①引导词:陈述句用that(可省略),一般疑问句用if/whether;②人称:直接引语的第一/二人称需根据主句主语/宾语调整,如直接引语的I对应主句主语时改为主语对应的人称,you对应主句宾语时改为宾语对应的人称;③时态:若直接引语是客观真理,时态不变,否则需根据主句时态调整(如一般将来时变过去将来时,一般现在时变一般过去时)。
【解析】
1. 原直接引语是陈述句,且“18th May is International Museum Day”是客观真理,时态无需变化,引导词用that,故填18th May is International Museum Day;
2. 原直接引语是陈述句,主语I对应主句主语Susan,需改为she;主句时态是一般过去时,直接引语的一般将来时will需变为过去将来时would,引导词that可省略,故填(that) she would give a report;
3. 原直接引语是一般疑问句,引导词用if/whether;直接引语的主语you对应主句宾语me,需改为I;主句时态是一般过去时,直接引语的一般现在时have需变为一般过去时had,故填if/whether I had。
【答案】
1. 18th May is International Museum Day
2. (that) she would give a report
3. if/whether I had
【知识点】
宾语从句转换(直接引语变间接引语)
【点评】
本题考查直接引语转换为宾语从句的基础知识点,涵盖引导词、人称、时态的变化规则,是初中英语的核心考点,难度适中,适合基础阶段学生巩固练习。
【难度系数】

3. Repeating lines from English movies
4. if/whether he spoke correctly
5. he suggested (that)

解析

【分析】
本题为根据汉语提示完成英语短文的题目,需结合英语语法规则(如形式主语结构、动名词作主语、宾语从句等)和语境,将汉语提示转化为正确的英语表达。解题时,先分析每个空在句中的成分,再对应汉语提示选择合适的英语结构和时态:1. 第一空需用it作形式主语的结构;2. 第二空是主句谓语,用一般过去时;3. 第三空在句中作主语,需用动名词短语;4. 第四空是宾语从句,用if/whether引导,时态匹配主句;5. 第五空是主句谓语,用一般过去时。
【解析】
1. 第一空:“很难相信”对应英语固定句式It is hard to do sth.,其中it作形式主语,真正主语是后面的that从句,故填It is hard to believe (that)。
2. 第二空:“他知道”描述过去的动作,用一般过去时,后接宾语从句,故填he knew (that)。
3. 第三空:“重复英语电影中的台词”在句中作主语,动名词短语可作主语,故填Repeating lines from English movies。
4. 第四空:“他是否说得正确”是宾语从句,用if/whether引导,主句为过去时,从句用一般过去时,“说得正确”译为speak correctly,故填if/whether he spoke correctly。
5. 第五空:“他建议”描述过去的动作,用一般过去时,后接宾语从句,故填he suggested (that)。
【答案】
1. It is hard to believe (that)
2. he knew (that)
3. Repeating lines from English movies
4. if/whether he spoke correctly
5. he suggested (that)
【知识点】
