高一英语感叹句和宾语从句

高一英语感叹句和宾语从句内容摘要：

属连词 whether和 if引导，含有“是否，能否，对否，有否”等一般疑问意义。 asked me if I could help her. Jim wanted to know whether I had taken his English book. find out whether the money is his or not. Please tell me whether you can e or not. Let me know whether you can e or not. 在这类宾语从句中要注意两点： I want to know whether you can help me or not. （ 1） if引导宾语从句和状语从句的区别 if引导宾语从句时意为“是否”，从句中该用什么时态就应用什么时态。 if引导状语从句时意为“假如”，从句中应用一般现在时代替一般将来时。 wanted to know if you were a teacher. I don’t know if the letter is yours. They’ll go boating if it is fine tomorrow. I’ll give it to her if she es next week. （ 2） if引导宾语从句时多数情况下可以与 whether互换，但如果要突出“究竟是 …… 还是不 ……” 层意思时，通常用 whether，并在后面的加上“ or not”, 在口语中偶尔也会用到“ if…or not” 这种形式。 使用宾语从句时要注意以下几点： 1．宾语从句要用陈述句的语序。 asked how old I was. My teacher wanted to know if I like English. We don’t know where her office is. 2．宾语从句的时态 （ 1）当主句的谓语动词是一般现在时时，宾语从句中的谓语动词不受时态限制。 says that she is a student. She says that she was a student two years ago. She says that she will be a college student soon. She says that she has been a college student for 3 years. （ 2）当主句的谓语动词是过去时时，宾语从句中只能用过去的某种时态。 told me that he would leave soon. He said that he was watching TV. He didn’t tell me whether he had finished this homework. （ 3）如果宾语从句中讲述的客观事实，一般真理成自。
