宾语从句(that 引导陈述句)练习指南
一、引言
在英语学习中,宾语从句是一种常见的语法结构,用于表达主句中动词的宾语内容。当宾语从句的内容是一个完整的陈述句时,我们通常会使用连接词“that”来引导这个从句(注意:在口语或非正式书面语中,“that”有时可以省略)。本练习旨在帮助大家掌握并熟练运用“that”引导的宾语从句来表达复杂的句子意思。
二、基本结构
主语 + 谓语 + that + 从句(陈述句)
- 例如:I know (that) he is honest.(我知道他是诚实的。)
注意:“that”作为连接词,本身无实际意义,但在正式文体或强调语境下不可省略。
三、练习题
练习一:将直接引语转换为间接引语(宾语从句)
直接引语:She said, "I am happy."
- 间接引语:She said that she was happy.
直接引语:He asked, "Do you like this book?"
- 间接引语:He asked if/whether I liked that book(注意:疑问句转换需用if/whether替代that)。
(提示:此题为陈述句转换)直接引语:The teacher said, "The earth revolves around the sun."
- 间接引语:The teacher said that the earth revolves around the sun.
练习二:根据上下文补全句子
I believe __________ (他会成功)。
- 答案:I believe that he will succeed.
She doubts __________ (这本书是否值得一读)。
- 答案:She doubts if/whether the book is worth reading(疑问性质,不用that)。
They know __________ (明天是星期天)。
- 答案:They know that tomorrow is Sunday.
练习三:改写句子,使其包含宾语从句
He is a good student. The teacher told us.
- 改写后:The teacher told us that he was a good student.
Will they come to the party? I want to know.
- 改写后:I want to know if/whether they will come to the party(疑问性质,不用that)。
(提示:此题为肯定陈述句转换) She finished her homework early. It surprised me.
- 改写后:It surprised me that she had finished her homework early.
四、注意事项
- 在将直接引语转换为间接引语时,要注意时态、人称和语态的变化。
- 当宾语从句为疑问句或否定句时,通常不使用“that”,而使用“if/whether”(疑问句)或相应的否定形式。
- 注意保持原句的语义完整性和准确性。
五、总结
通过本次练习,你应该能够熟练掌握“that”引导的宾语从句的基本结构和用法,并能够在实际语境中灵活运用这一语法点。记得多做练习,以巩固所学知识并提高语言运用能力。
