Alice is one of the students,who,I'm sure,are proud of their English teacher.

问题描述:

Alice is one of the students,who,I'm sure,are proud of their English teacher.

我确信alice是令英语老师引以为傲的学生之一。这里who引导的定语从句修饰先行词students,在具体做题时可以把I'm sure作为插入语对待,这样可以帮你快速分析句子。

Alice is one of the students,who,I'm sure,are proud of their English teacher.--------变成两个简单句,然后你就明白了:
===Alice is one of the students.The students are proud of their English teacher,I am sure
