1. I want to question my belief, so that what is left after I have questioned it, will be even stronger．

文法解析：so that是复合连词，意思是“以至于......结果是......”，引导结果状语从句。例如：

Everyone lent a hand, so that the work was finished ahead of schedule. 每个人都帮了忙, 所以工作提前完成了。

So that还有“以便于......”的意思。例如：

I will give you all the facts so that you can judge for yourself. 我会给你所有的事实以便你可以自己判断。

I stepped aside so that she might come in. 我往旁边走一步，以便她能进来。

2. But Angel,your mother and I have saved and saved to send you to university like your brothers．

要点解析：saved and saved这里的动词save使用了2次，save and save的意思是“节省了又节省”，有些动词也可这样使用，例如：

Mary have studied and studied but she gains nothing. 玛丽学了又学，可是毫无收获。

3. But how can we send you there if it is not in the service of God？

语言要点：in the service of：为......服务，造福于......

e.g. He died in the service of his country. 他为国捐躯。

e.g. Their work is in the service of the people. 他们的工作是为人民服务。

4. So Angel did not have the advantage of a university education．

语言要点：have the advantage of：处于......优势，处于......有利条件

e.g. He has the advantage of a good education in America. 他具有在美国受过良好教育的有利条件。

e.g. Whatever the weight of antiquity, truth should always have the advantage.无论古人的份量有多么重，真理总是占着优势。

5. After some years studying at home he decided to learn farming．

要点解析：studying在这里是作为名词用，意思是“研究学习”。Farm在这里是作为动词用，意思是“经营农场，务农”，在动词learn是及物动词，后面跟farm这个动词，因此使用的是其动名词形式。
