一个英语问题

Question

what renders me qualified and competent is,in my own view,( my rich experience make me a perfect candidate for it.)
问题1、括号里面是不是应该加上that？即改为：that my rich experience make me a perfect candidate for it。因为这是一个表语从句，我分析的对么？
问题2、what renders me qualified and competent is为什么在这句话中有两个动词？render和is。
what renders me qualified and competent is这句话的句子成分究竟该怎样划？render和is这不是矛盾嘛，为啥一句话可以出现两个动词形式的词语？

谢谢！

Answer 1

这句话的结构比较复杂，其实应该是两个句子：

1 what renders me qualified and competent is, in my view, my rich experience.
2 My experience makes me a perfect candidate for it.

这样就比较明白了。但我觉得原句这样写虽然从语法结构上似乎没有问题，但如果作为主语从句+系动词+表语从句来理解：

[使我合格且称职的][是][我的丰富经验让我成为（职位的）最佳候选人]。

文意重复，显得很奇怪。

就你的问题，在1句中，what renders me qualified and competent 是疑问词引导的主语从句，系动词is是全句的谓语，my experience是表语,而in my own view是独立成份。这句还可以改写为这样更好一些：
It is my rich experience, in my own view, that renders me qualified and competent.

全句也可以改为：
what renders me qualified and competent and makes me a perfect candidate for it is,in my own view, my rich experience.

或者这样，更好一些：
It is my rich experience，in my own view, that renders me qualified and competent and makes me a perfect candidate for it.

基本上是这样，希望对你有帮助。

Answer 2

1. what renders me qualified and competent 是一个由 what 引导的主语从句，既然是从句，必然要有其谓语动词 render，意思是“给予我具备资格和能力的东西”；
2. 正如你所说，that my rich experience make me a perfect candidate for it 是表语从句，意思是“我丰富的经验使我成为其候选人”
3. is 是联系 what 主语从句和 that 表语从句关系的的系动词。
4. 插入状语：in my own view
整体翻译：依照我个人的见解，所给予我资质和能力的是我丰富的经验使我成为其候选人这件事。
