1.It is said that a Chinese ruler called Shen Nong ..
It is said that...中的It作形式主语，真正的主语是that引导的从句。该结构相当于“People say that…“。
例如：It is said that she works as a director.
与此类似的结构还有：
It is believed that… 人们认为……
It is reported that… 据报道……
It is （well）known that… 众所周知……
One day Shen Nong was boiling drinking water …
boiled water开水（形容水被烧开的状态）；
boiling water沸水（形容水正在沸腾的状态）
It produced a nice smell …
smell /smel/ n.气味 v. 发出......气味；闻到
（1）smell在此处作可数名词，意为“气味”。smell还可作不可数名词，意为“嗅觉”。
The flower has a sweet smell.
（2）smell还可作系动词，意为“有......气味，发出......气味”，后接形容词作表语。

（3）smell也可作及物动词，意为“闻到，嗅到（气味）”。

The tea trade from China to Western countries took place in the 19th century. take place 发生；举行
take place为不及物动词短语，不能用于被动语态。指根据安排或计划发生，含有事先预料或计划的意思。
The 2022 Winter Olympics will take place in Beijing, China.
happen意为“发生”，为不及物动词，不能用于被动语态。指具体客观事件的发生，有偶然性，未能预见。

5. … the Chinese are without doubt the ones who best understand the
nature of tea. without doubt 毫无疑问；的确
without doubt可与there is no doubt that进行同义句转换。其中doubt作名词，意为“疑问；疑惑” 。
He is without doubt the best teacher in our school.
There is no doubt that he is the best teacher in our school.
语法重点：
