1.He gives me a book of great use.
of great use 做后置定语,修饰book.
2.I find the book of great use.
of great use 充当宾语book的补足语.
同学,语法书上有很详尽解释什么是定语什么是补足语.我就不累赘了.
我下面将这两句话变一下,
1.1 He gives me a grealy useful book.greatly useful 做定语.
2.1 I find the book greatly useful.greatly useful 做宾语补足语.
PS:第二句还可以改成:i find that the book is of great use.做宾语从句中的表语.
而第一句不能这么改.能懂了吗?欢迎追问!
