我从不怀疑英语

There is no doubt that I will be a good wife as well as good mother.用There be的结构更强调客观，比I做主语更语气强烈。

I never doubt that I'll be a good wife and loving mother.注意：用单数wife / mothera good wife and loving mother 贤妻良母

6. did I doubt考查部分否定结构的应用 u 本句虽然含一个插入语"the boy says"，但直接引语部分仍然遵循了部分倒装结构的规律，即"否定状语在句首，主谓结构部分倒装"的规律。倒装方式见第1题解析所述。

I have never doubted that this book is very much worth a readI have never doubted that this book is very much worth reading皆可以

your promise ,i never suspect,your pledge ,i never have suspicion

I let you enter my world,but I never suspect you. 这样合适吗？不了解语境所以不知道具体该用哪些词。

I never doubt that I will be a good wives and good mothers
