大家帮我看看这是什么从句？

Question

1. I could only give him what I believed was the sum of his life. 这是什么从句？ 2. Another technique employed by top students is to do more than the assigned homework. 为什么不是another technique is employed 少了一个be动词

Answer 1

1 是宾语从句，因为give 是双宾动词
2 因为这个employed 是过去分词，表被动，不能加is ，因为整个句子已经有了谓语动词is (to do ) 的is了，这是非谓语范畴
