Step1 Discover rules:  Attributive clauses(2)

此活动聚焦课文素材，引导学生自己去发现、总结限制性定语从句中关系副词的使用规律。教师仅作为辅助者、监督者，为学生提供支持性信息。

第一步：学生独立朗读例句，关注粗体部分，尝试理解粗体部分表达的含义。

第二步：学生分组，各小组对比两组例句，基于活动中的问题展开讨论，发现两组例句在句子结构上的不同之处，归纳限制性定语从句的表意功能、关系副词的基本用法及限制性定语从句在语篇层面的效果。

第三步：请个别小组分享答案并总结限制性定语从句和关系副词的表意功能和用法，根据学生水平酌情进行补充和拓展。

第四步：请学生独立在课文中找出更多由关系副词引导的限制性定语从句，体会其用法和表意功能。

Look at the sentences from the reading passage and answer the questions.

a Eventually, it manages to reach the places where it will spend the winter.

b The solution… comes at a time when it is in serious trouble.

c Sadly, human activity is the main reason why the number of monarch butterflies is falling.

1 What do “where”, “when” and “why” refer to in each sentence?

Compare them with the following sentences and answer the questions.

d Eventually, it manages to reach those places. It will spend the winter there.

e It is in serious trouble. The solution… comes at this time.

f Sadly, human activity is the main reason. For this reason, the number of monarch butterflies is falling.

2 What’s the difference between the two groups of sentences?

3 Why does the author choose to use sentences (a), (b) and (c) in the reading passage?

○参考答案

1 “Where” refers to “the places” in sentence (a), “when” refers to “a time” in sentence (b) and “why” refers to “the main reason” in sentence (c).

2 Sentences (a), (b) and (c) contain a clause defining a noun or pronoun in the sentence. Sentences (d), (e) and (f) are constructed with a pair of simple sentences, with one defining a noun or pronoun in the other sentence in each pair.

 3 Because there is a closer link and connection between the item and the clause defining it in sentences (a), (b) and (c). It will also make the passage clearer, and create an emphatic effect on the location, time and reason being defined.

Step2  Presenting

定语从句关系副词讲解

定语从句中关系副词的基本用法如下。

1 where

在定语从句中用作地点状语，其先行词须是表地点的名词。

例如：This is the school where I studied a few years ago.

2 when

在定语从句中用作时间状语，其先行词须是表时间的名词。

例如：Can you tell me the time when the film

will start?

3 why

在 定 语 从 句 中 用 作 原 因 状 语， 其 先 行 词 一 般 是

reason(s)。

例如：Do you know the reason why he is not here?

Step3 Reading

教师带领学生了解中国大熊猫到达荷兰后的情况，使学生在真实语境中巩固对定语从句的理解。

第一步：学生独立阅读语篇，整体理解语境和语篇大意。

第二步：学生分组，按要求画出语篇中关系副词所指代的内容。

第三步：请个别学生分享画出的先行词，全班核对答案。

Read the passage and underline the words that where, when and why refer to.

In April 2017, two giant pandas from China arrived at a zoo in the Netherlands. There, they were welcomed to the Chinese-style compound where they were to live. On 30 May, after the preparations were complete, the day finally came when the pandas met their fans for the first time. People were

excited – the zoo is the only place in the country where it is possible to see pandas. In fact, the last time there were pandas in the Netherlands was in 1987.

And of course, the main reason why they were so excited is that pandas are just so cute!

○参考答案

where – the Chinese-style compound

when – the day

where – the only place in the country

why – the main reason
