grammar 急問

It is because mathematics is important, partly due the its application in physics, partly because of its contribution to our lives.

because -------, due to ---- because of ------- 這grammar有冇問題???
It is not so right to throw the words in blue in your long sentence.
Here is my version anyway.
The reason why I have chosen maths is that it is very important and challenging and I have been so fond of studying it since I was little.

Its applications in physics along with its contributions to science and our lives are the factors that influence all mankind.
1) applications<----- countable noun
contributions<------- countable noun
2) The blue part shows that you have been so fond of studying maths since you were little and.....................
Hope that helps.
See you^_^

If you are still in doubt, you may send your question(s) to my email account.

yes, I agree with lingthk
.
If I just read the answer for the above page, answer 001 is definately more suitable.

However, some of the answer from 002 were provided through email.

That indeed help me more.

Having read the answers, I think answer oo1 is more appropriate.

全句可以這樣改：
I choose maths because mathematics is important, partly due to its application in physics, and partly because of its contribution to our lives.
但有些文化學者認為在動詞之後或從句之首應用owing to表示”因為”，因為due是形容詞
你的句子也有人會這樣寫：
I choose maths because mathematics is important, partly because of its application in physics, and partly because of its contribution to our lives.（用相同的because of會更順暢）
希望幫到你！
