While I tend to buy a lot of books, these three were given to me asgift, which might add to the meaning I attach to them.
请问这句话中的I attach to them干什么成分？
which might add to the meaning I attach to them这句话不是有个add 作谓语动词吗？为何 attach不需要非谓语动词形式？
While I tend to buy a lot of books, these three were given to me as gifts, which might add to the meaning I attach to them.
I attach to them为定语从句修饰the meaning，省略了作宾语的关系代词that。
