1. Did you know that tea, the most popular drink in the world (after water),
was invented by accident?
你知道茶这种世界上最受欢迎的饮料（仅次于水）是偶然被发明的
吗？
(1)本句是that引导的一个宾语从句，主句是 Did you know，其中从句的
主语是tea, 而the most popular drink in the world (after water), 是tea的同位
语。
(2) by accident意为“偶然;意外地”。
►I met Tom on the street this morning by accident.

2. It is said that a Chinese ruler called Shen Nong was the first to discover tea
as a drink.
据说有一位叫神农的中国统治者最早发现了茶可以饮用。

句为真正的主语。
► It is said that he is the richest man in this small town.
据说他是这个小镇上最富有的人。
(2) ruler名词，意为“统治者;支配者”
► A king is a ruler. 国王是统治者。
其他常见“It is ...that”句式
It is: believed that… “据认为……”
reported that … “据报道……”
known that… “众所周知……”
supposed that… “据推测……”
the first to do sth. 意为“第一个做某事的人”，是“the + 序数词+to do
sth.”结构，动词不定式作定语。

例句：
►We got there in less than two hours.
不到2个小时我们就到那儿了。
►He sleeps less than seven hours every night.
他每晚的睡眠时间不到7小时。
反义词组为： more than=over 超过；多过
5. take place发生；出现
常指有计划、有安排地“发生”，是不及物动词短语，不能接宾语，一
般也不用作被动结构。例句：
本学期家长会将在大厅举行。
