[探究] 1．以上例句中黑体单词为关系词，引导定语从句。 2．句1中whose指代Tu Youyou's；句2中where指代in Hainan；句3中that指代ancient Chinese medical treatments；句4中whom指代malaria patients；句5中which指代This medicine。 3．句1、2、4、5中，定语从句前有逗号。 1．思考什么是非限制性定语从句。 2．思考非限制性定语从句与限制性定语从句有何区别。 3．思考如何选择非限制性定语从句中的关系词。 一、定义 [感知] 1．This is the computer (that/which) he bought for his son yesterday. 这是他昨天为他儿子买的电脑。 2．The woman who/that survived the earthquake is Amy's English teacher. 在地震中幸存的那位女士是埃米的英语老师。 3．He is English，which I know from his accent. 他是英国人，我是通过他的口音知道的。 4．This is our headmaster，who I think has something important to tell you. 这是我们的校长，我认为他有重要的事情要告诉你。 [探究] 1．句1、2是限制性定语从句。在意义上是先行词不可缺少的定语，用于修饰和限定先行词。如果去掉，主句的意思就不完整。这种从句和主句的关系十分密切，两者之间一般不用逗号分开；关系代词在从句中作宾语时可以省略。 2．句3、句4中从句与主句之间有逗号隔开，从句和主句的关系不是十分密切，句3中定语从句是对He is English这一事实进行的附加说明；句4中定语从句是对our headmaster进行了附加说明。 3．句3、4中如果去掉从句，主句的意思仍然完整。 [归纳] 非限制性定语从句是对先行词或整个主句的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开；将非限制性定语从句放在句子中间时，其前后都需要用逗号隔开。 [即练] 单句填空/完成句子 ①(2022·新高考Ⅰ卷)The GPNP is intended to provide stronger protection for all the species that live within the Giant Panda Range and significantly improve the health of ecosystem in the area. ②They were well trained by their masters who had great experience with caring for these animals. ③来自澳大利亚的霍莉精通中文。 Holly，who is from Australia，has a good command of Chinese. ④老师昨天买的那本字典对我们很有帮助。 The dictionary，whic
