五、Language Points
1. It is said that a Chinese ruler called Shen Nong was the first to discover tea as a drink.据说是一位叫作神农的中国统治者最早发现茶可以饮用
要点精析
“It is said that从句”是含有that从句的一种复合句，形式主语是it，that引
导的从句作真正的主语，意为“据说......”，相当于People say that...。
使用该句型时，that从句的谓语动词可根据需要用各种时态
例:tis said that they have won the game.据说他们已经赢得了那场比赛
Itis said that they will go abroad soon.据说，他们不久将要出国
2. WellI think the TV was invented after the car.哦，我认为电视在小汽车之后被发明
要点精析 1
这是一个主从复合句，think后面跟了一个宾语从句。因为主句用一般现在时，从句根据句意用一般过去时。
小贴士
在主从复合句中，如果主句是一般现在时，从句可根据实际情况选用时态，如果主句用了过去时态，那么从句也应该使用过去的某种时态(客观真理除外)
例: He said he would leave next week.他说下周他就离开
3. Even though many people now know about tea culture, the Chinese are
without doubt the ones who best understand the nature of tea. 即使现在很
多人都了解茶文化，但毫无疑问中国人才是最懂茶的本质的人
要点精析 1
without doubt意为“毫无疑问:的确”
例: It is without doubt that people pay more and more attention to their health
毫无疑问，人们越来越重视健康。
要点精析 2
who best understand the nature of tea是由who引导的定语从句，修饰前面的
theones，who在从句中充当主语
例:Ilike someone who can make melaugh.我喜欢能让我发笑的人
4. The earthquake happened all of a sudden...地震突然发生.....
要点精析
all of a sudden 意为“突然地”
例:
The girl began crying all of a sudden.这个女孩儿突然开始哭了起来
知识拓展
sudden adi.突然的;意外的
例: His sudden death made his family very sad
他的突然去世使他的家人很悲伤
suddenly adv.突然地
例: Suddenly he ran out of the house without a word.
突然，他一句话都没说就跑出了房子
六、Grammar Focus
1一般过去时的被动语态的构成
由“was/were+及物动词的过去分词”构成。被动语态的时态变化只改变be的
形式，过去分词部分不变。疑问式和否定式的变化也是如此
2被动语态的用法
(1)不知道或没有必要指出谁是动作的执行者时
例: The bridge was built last year.这座桥是去年建造的。
(2)当更加强调动作的承受者时，动作的执行者由by引导，置于谓语动词之后，不需要时可以省略。
例: The letter was written by him.这封信是他写的
(3)当动作的执行者是泛指时(如people，one等)，多用被动语态
例: These clothes are said to be very popular abroad
据说这些服装在国外很流行
七、Practice
