1. 重要语法：宾语从句：在复合句中充当宾语的句子。
本模块重点：由that引导的宾语从句，that 无义，可省, 后接陈述句作宾语。

I can hardly believe (that) we’re in the city centre.
Tony guesses that the park is very popular.
Lingling suggests that they spend the day there.
Lingling doesn’t think the park will be busy.
主句和从句的时态关系：
①主句：一般现在时 从句：需根据实际情况用不同时态
She says (that) she works from Monday to Friday.（从句为一般现在时）
She says (that) she will leave a message on his desk. （从句为一般将来时）My grandparents often tell me they lived a hard life in the past.（从句为一般过去时）

He said (that) he was going to take care of the baby. （从句用过去将来时）
Our teacher told us he had taught here for 20 years. （从句用过去完成时）
③特殊情况：从句描述的是客观事实、真理、科学名言警句等不以时间改变而改变的事实时，不管主句为何种时态，从句总是用一般现在时。
He said that light travels much faster than sound.   他说光比声音传播得快)
The teacher told us the earth goes around the sun. （客观事实）
She said(that) her father is twenty-eight years older than her. （客观事实）
My father told us(that) nothing is difficult if we put our hearts into it.（客观真理）
注意：当主句的谓语动词是think或believe，宾语从句要表达否定时，要把从句的否定转移到主句上。 
I don't think he is going to help you with your English. 
We don’t believe that we have won the basketball match.
2. hardly 几乎不= almost not

M9
基本结构：主句+if/whether+宾语从句（用陈述语序）
1.重要语法：①if/whether 引导的宾语从句复合句，if/whether意为“是否”，用在将直接引语（说话人说得话）为一般疑问句的简单句转化为间接引语（转述他人的话）的复合句中做引导词，转化后需将一般疑问句变为陈述句，即陈述语序。

（直接引语）“Are you a teacher?” he asks.
（间接引语）He asks if/whether I am a teacher.
（直接引语）“Have you finished your home work?”the teacher asked him.
（间接引语）The teacher asked if/whether I had finished my home work.
间接引语也就是if/whether 引导的宾语从句
He wants to know if it will rain tomorrow.
I don’t know whether he is at home or not.
注：if 和whether 一般情况下可以互换使用，但如下情况，不能用if,只能用whether:
⑴在动词不定式之前只能用whether
I don't know whether to accept or refuse（拒绝）.
⑵在whether …… or not 的固定搭配中。
Let me know whether you can come or not.
⑶ 在介词后，只能用whether。
I worry about whether I hurt her feelings.
⑷宾语从句放在句首表示强调时，只能用whether 。
Whether it is true or not, I can't tell.
⑸用if会引起歧义时，只用whether。如用whether可避免歧义。
②特殊疑问词引导的宾语从句（what/where/when/which/why/how/how many…）
基本结构：主句+特殊疑问词+宾语从句（用陈述语序）

直接引语为特殊疑问句的简单句转化为间接引语复合句时，用原来的特殊疑问词作引导词，但后面需改为陈述句，即陈述语序。
（直引）“What’ s your name?”Mr. Li asks me.
（间引）Mr. Li asks what my name is.
（直引）“Why did he ask for help?” he asked.
（间引）He asked why he asked for help.
间引即为特殊疑问词引导的宾语从句。
Where does he come from? I don’t know.（合并句子）
I don’t know where he comes
