教材分析

本节为语法课, 学习被动语态和句子中的主谓一致, 教师通过讲解和练习, 帮助学生解决英语学习中的难点, 培养抽象思维能力。动词的语态主要分为两种: 主动语态和被动语态。主动语态是指主语是谓语动词的执行者, 二者为主动关系。被动语态是指主语是谓语动作的承受者, 二者为被动关系。主谓一致指的是句子的谓语动词与其主语在数上必须保持一致, 句子的主语是第三人称单数, 主语是复数, 则谓语动词用复数。

教学过程

→ Step 1 Revision

Revise what we have learned last class.

1. Make students discuss in pairs to complete the following table.

(Show the following on the screen. )

Famous place(s)in the city Other special features

City’s name Country the

city belongs

to

Paris France Eiffel Tower, the Louvre Restaurants, ca fés and theatres,

famous writers

Barcelona Spain The Sagrada Familia /

Florence Italy The Uffizi Palace Famous for Renaissance, greatest

painters

Athens Greece The Parthenon The birthplace of western

civilisation, best writers

2. Encourage students to choose a city from the table and introduce it to the whole class using the information.

→ Step 2 Grammar 1: Passive Voice

1. Ask students to read through the sentences in Activity 1, Page 5 and then discuss with their partner the following questions:

1)Wha t does the word “by” in the first three sentences tell you?

2)Is there any difference in meaning between these two sentences?

Paris is visited by more than eight million tourists every year.

More than eight million tourists visit Paris every year.

3)Why is the word “by” not in the sentences d and e?

(After a few minutes’ discussion the teacher may ask students to answer the questions)

Suggested answers:

1)It tells us who did the action. (In grammatical terms: It tells us who the agent was. )

2)The focus is different. In the first sentence it is Paris which that is more important; while in the second one we are more interested in the tourists.

3)In sentence d, because we understand that it means “is known by everyone”, and the inclusion of the agent would be superfluous, while in sentence e because we are not interested in who built it.

2. Option One

Encourage students to sum up the structure of Passive Voice.

Take the verb “do” as an example.

Write the following on the blackboard and give them a few minutes to complete the table.

时态主动语态被动语态

一般现在时do/does am/is/are+done

一般过去时did was/were+done

现在进行时am/is/are+doing am/is/are+being+done

过去进行时was/were+doing was/were+being+done

现在完成时have/has+done have/has+been+done

过去完成时had+done had+been+done

一般将来时will+do will+be+done

过去将来时would+do would+be+done Option Two

Show the grammatical rules on the screen and have students make sense of them.

被动语态的结构

一般来说, 只有需要动作对象的及物动词(短语)才有被动语态。动作的执行者一般由介词by 引起的短语来表示(by短语常可以省略)。被动语态由“助动词be+过去分词”构成。现以动词do 为例, 列出常用的八种时态的被动语态。

(1)一般现在时: is/am/are+done

How is this word pronounced?

这个单词怎么发音？

(2)一般过去时: was/were+done

She was asked to sing a song.

大家要求她唱首歌。

(3)一般将来时: will/shall+be done或is/am/are going to+be done

Some of you will be sent to America for further training.

你们中有些人将被送到美国接受进一步的培训。

(4)现在进行时: is/am/are+being done

The classroom is being cleaned by the students.

学生们正在打扫教室。

(5)现在完成时: have/has+been done

All the work has been finished.

所有工作都已完成了。

(6)过去进行时: was/were+being done

Mom told me that grandma was being taken good care of in that nursing home.

妈妈告诉我奶奶在那个疗养院被照顾得很好。

(7)过去完成时: had+been done

It was the first time that I had been criticized in public.

那是我第一次当众挨批评。

(8)过去将来时: would+be done

He did know he would be assigned the complex job.

他就知道这项复杂的工作会安排给他。

情态动词的被动结构为“情态动词+be done”。

Everything that can be done has been done.

能做的都已经做了。
