Step 3 Summary One: Language points1. 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. 今天早上，我偶然间在街上遇到了汤姆。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。 (1) It is said that…表示“据说……”，其中it 是形式主语，that引导的从句为真正的主语。 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： Mary is always the first to come to the classroom. 玛丽总是第一个到教室。 You are the second to sing in the party. 你是第二个向在晚会上唱歌的人。3. Some leaves from a tea plant fell into the water and remained there for some time. 一株茶树上的几片叶子落到水里并停留了一段时间。 (l) fall into意为“落人;掉入”。 He didn’t see the stone on the road and fell into the pool. 他没看见路上的石头，跌落到池子里面。拓展：fall asleep 睡着 fall behind 落后 fall down 跌倒；倒塌4. less than意为“较少，比……少；不及，不如”。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。 This term, the parents meeting will take place in the hall. 我们学校每年举行一次运动会。 The sports meeting takes place every year. 知识链接:take place 和 happen的用法与区别1) take place 表示“发生、举行、举办”，一般指非偶然性事件的“发生”，即这种事件的发生一定有某种原因或事先的安排。 Great changes have taken place in our hometown during the past ten years. The Olympic Games of 2008 took place in Beijing. 2) happen作“发生、碰巧”解，一般用于偶然或突 发性事件。 What happened to you 你怎么了？ Maybe something good will happen.注意：happen 与 take place 通常都没有被动语态。2) happen作“发生、碰巧”解，一般用于偶然或突 发性事件。 What happened to you 你怎么了？ Maybe something good will happen.注意：happen 与 take place 通常都没有被动语态。
