教学重点难点

以……著名[其同义词组为be (well)known for
Hangzhou is famous for its beautiful scenery. 杭州以优美的风景而闻名。
be famous for 与be famous as的区别
1) 当主语是表示人的名词
be famous for表示“以某种知识技能、作品或特征而出名”
be famous as则表示“以某种身份而出名”
Einstein was famous for his Theory of Relativity. 爱因斯坦以他的相对论而出名。
Einstein was famous as a great scientist.爱因斯坦以一位伟大的科学家而著称。
2) 当主语是地点名词
be famous for表示“以某种特产而出名”
be famous as则表示“以什么样的产地或地方闻名”
The area is famous for its green tea.这个地区以绿茶而出名。
The area is famous as a great tea-producing place.这个地区以绿茶产地而出名。
3)当主语是事物名词
be famous for表示“以其内容、特征、价值等而被人所知”
be famous as则表示“以某种形式而出名”

This book is famous as a reference book.这是一本有用的参考书。
注意：be famous for后的介词宾语是主语所属内容，而be famous as后的介词宾语与主语是同位成分。例如：

2.kind, sort和type的区别

sort 可与kind互换使用，但较为含混，有时只表示大概此种而已。Sort有时有轻蔑的意味，相反kind 要庄重得多。

type则指型，类型，比较具体，肯定等，而kind比较笼统，模糊。
