教学过程
Step Ⅰ 学习理解
活动一:识别非限制性定语从句
Read the following sentences and underline the relative clauses.Then name the two types of clauses and state their functions.
① They tested hundreds of Chinese medical treatments that showed promise in the fight against the disease. ② Tu Youyou was awarded the Nobel Prize,which is considered one of the highest international honours a person can receive. ③ Tu Youyou went to Hainan,where malaria was more common,to study malaria patients. ④ Later,the medicine was tested on malaria patients, most of whom recovered. ⑤ This medicine,which was called artemisinin,soon became a standard treatment for malaria.
Suggested answers:
① They tested hundreds of Chinese medical treatments that showed promise in the fight against the disease.
(restrictive,describe the kind of medical treatments they tested)
② Tu Youyou was awarded the Nobel Prize,which is considered one of the highest international honours a person can receive.
(non-restrictive,give extra information about Nobel Prize)
③ Tu Youyou went to Hainan,where malaria was more common,to study malaria patients.
(non-restrictive,give extra information about Hainan)
④ Later,the medicine was tested on malaria patients,most of whom recovered.
(non-restrictive,give extra information about the patients)
⑤ This medicine,which was called artemisinin,soon became a standard treatment for malaria.
(non-restrictive,give extra information about the medicine)
【备注】语法知识点讲解详见第二教案“重点语法精讲”。
【设计意图】介绍对社会有突出贡献的人物屠呦呦时,课文中用了定语从句,增加了表达效果。从课文中列举出一些含有定语从句的句子,使学生在具体语境中识别定语从句,分析句子结构,区别限制性定语从句和非限制性定语从句,初步认识和理解非限制性定语从句的功能和意义。
Step Ⅱ 应用实践
活动二:改写句子
Rewrite the sentences using non-restrictive relative clauses.How do the sentences flow differently?
EXAMPLE
The book tells us about Alexander Fleming. He discovered penicillin.
→The book tells us about Alexander Fleming,who discovered penicillin.
① We were very impressed by the old man. He was not willing to acknowledge defeat. ② Afterwards,Einstein had to flee Germany. Hitler was in power there. ③ There is nothing we can do to help Linda. Her circumstances are beyond our control. ④ The teacher asked us to listen to a speech by his favourite novelist,J. K. Rowling. It inspired us a lot. ⑤ The building under construction was designed by I.M. Pei—a famous Chinese-American architect. He was born in Guangzhou,China. ⑥ I was asked to explain the project with the help of a flow chart. It was a big challenge for me.
Suggested answers:
① We were very impressed by the old man,who was not willing to acknowledge defeat.
② Afterwards,Einstein had to flee Germany,where Hitler was in power.
③ There is nothing we can do to help Linda,whose circumstances are beyond our control.
④ The teacher asked us to listen to a speech by his favourite novelist,J K. Rowing,which inspired us a lot.
⑤ The building under construction was designed by I.M. Pei—a famous Chinese-American architect,who was born in Guangzhou,China.
⑥ I was asked to explain the project with the help of a flow chart,which was a big challenge for me.
In each case,there are two short sentences which look like separate to each other. By combining the two simple sentences together using non-restrictive relative clause, the sentence becomes more varied and has better flow.
【设计意图】通过分析两个简单句中相同的部分,然后使用恰当的关系词将其中一个相同部分替换,从句前加逗号,从而将两个简单句改写成非限制性定语从句,以此让学生在练习中感受、总结出选择非限制性定语从句关系词的技巧并正确使用。
Step Ⅲ 迁移创新
活动三:情境应用
Work in plete the sentences using non-restrictive relative clauses to give extra information.Then share them with your group members.
EXAMPLE
I’d like to try…,…
→I’d like to try that Chinese herbal medicine again,which seems to work best for my cough.
① I would like to travel around…,… ② What impressed me most…,… ③ My favourite scientist is…,… ④ Finally we arrived at…,… ⑤ My grandparents like…,… ⑥ I wish to obtain…,… ⑦ My best friend…,…
Suggested answers:
① I would like to travel around Sichuan Province,where Jiuzhaigou locates.
② What impressed me most about the film was the ending,which was quite moving.
③ My favourite scientist is Nikola Tesla,who was quite brilliant but also had some crazy ideas.
④ Finally we arrived at the zoo,which was closed for repairs.
⑤ My grandparents like going for outings in spring,which is good for their health.
⑥ I wish to obtain a driving licence,which is necessary if you want to drive a car.
⑦ My best friend came to visit last week,which was the first time I had seen him in years.
【设计意图】在学习和练习了非限制性定语从句的用法之后,把语法置入现实生活情景中,学生结合自己的具体情况,用非限制性定语从句补全句子,在特定的语境中使用、理解非限制性定语从句,表达自已的想法,这加深了对非限制性定语从句用法的理解,改变了单纯的语法练习,提高了学生学习语法的兴趣。
