(1)What do you think the text is about when you read the title
(2)What's the text about according to the picture

任务驱动二 精读短文,品味细节

(1)When was tea first drunk
(2)How was tea invented
(3)Who is called “the sage of tea”
(4)What is Cha Jing about
(5)When was tea brought to other countries
　　◎学法指导:阅读小技巧:
抓住四个“W”和一个“H”,就是边读边用铅笔做些标记,把What (事件),When(时间),Where(地点),Why (原因),How (经过)画出来。抓住了四个“W”和一个“H”,就抓住了文章的全貌,一些直接性的问题便可解决。
2.再次精读短文,完成3c中的练习。
任务驱动三 读一读,想一想,练一练
　　1.观察下列被动语态句子。
①Tea was invented by accident.②Tea wasn't brought to the western world. ③It's used for serving really cold ice-cream. 尽可能多地小组讨论,归纳总结主动语态变被动语态的语法规则,熟记运用口诀:宾变主, 主变宾, 谓变be done,时不变,数、格必须随着变。
2.完成4a。Rewrite the sentences using the passive voice.
3.完成4b。Complete the sentences with the correct forms of the verbs in the box.
4.完成4c。Decide whether active or passive forms should be used in these sentences. Write the correct forms in the blanks.
　　◎学法指导:学习体会被动语态的使用。被动语态是由“助动词be或动词get+过去分词”构成的,过去分词保持不变,而所有的变化,即人称、数、时态的变化,都体现在助动词be或动词get的变化上。
