Step 4Step 1. Grammar 1 — Non-defining relative clause

1. Ask Ss to read out the sentences in Activity 1 and translate them into Chinese.

2. Ask Ss to answer the questions in Activity 1 individually and check with their partners. Then give them the right answers.

3. Give Ss some explanation.

(1) A relative clause that contains essential information about the subject is called a defining relative clause. A relative clause that contains extra information about the subject is called a non-defining relative clause.

(2) 限制性定语从句修饰前面的名词，清楚表达了所修饰的名词的特征。如：

Mao Zedong wrote a poem in which he dreamed of “walls of stone to hold back clouds and rain”。 毛泽东写了一首“更立西江石壁，截断巫山云雨，高峡出平湖”的词。

The ice which covers the South Pole has begun to melt. 覆盖南极的冰已经开始溶化了。

(3) 非限制性定语从句位于确定的名词之后，对这类的名词不做限制性的描述，只是对该词进一步说明和补充。这类从句即使省略也不会引起意义上的混乱。由逗号隔开。如：

Sun Yat-sen, who was the leader of the 1911 Revolution, first suggested the idea in 1919. 早在1919年，领导了辛亥革命的孙中山就首次提出了要在长江上修筑大坝的设想。

He designed the first “web browser”, which allowed computer users to access documents from other computers. 他设计了第一个网络浏览器，从而使电脑使用者可以从其它电脑中获取文件。

4. Ask Ss to do the exercises in Activity 2 as follows:

(1) Ask Ss to underline the attributive clause in each sentence.

Suggested Answers:

① who became President of the Republic of China in 1912

② which is the world’s longest canal

③ which was built in the seventh century

(2) Ask Ss to discuss if the sentences are defining relative clause or non-defining relative clauses. Get them to add commas if necessary.

5. Ask Ss to do Activity 3 individually, then check with a partner. Give the right answers and some explanation if necessary.

6. Ask Ss to translate the following sentences into English.

(1) 你昨天在校门口遇见的老人是一位教授。

(2) 这位老人是个教授，他已经80岁了。
