一、总结宾语从句：

(一)由wether /if 引导的宾语从句

如果我们想要表达一个不确定的概念，比如说“记不清、不知道、想知道”等等，就要用whether/if 表示。从句后面还有or not 的话，一般要选用whether, 构成

whether ….or not的结构。

1.Do you know if Sally Maxwell has arrived?

2.Can I ask you if you miss the UK?

3.I asked your secretary whether she could come or not.

练习：

1.他问我是否有空。

He asks me _____________________.

2.Is the post office over there ? He wanted to know. 合并成含有宾语从句的复合句子

(二)由that 引导的宾语从句

当谓语表示肯定的概念时，如“希望、相信、知道、说”其后面的句子一一般用that引导。

1.I’ve heard that you play in your school orchestra.

2.I know that foreigners find China very different from their own countries.
