Hi Zhang,
As the development of education is a crucial symbol of the societal development standard,who should assume the obligation in educational payment has sparked off a heated debate beyond our widest expectionexpectation
I think your sentence is so long, and I cannot relate your introductory sentence to the main sentence. The subject of the main sentence is itself complected enough (
who should assume the obligation in educational payment ) , adding an introductory sentence exacerbate the situation .( I do not know whether my English is poor or your's is a bit complex)
Personally,I am in favour of the idea that the primary and secondary education should be paid for by the government while the further education is beyond its responsibility.
If the development( what do you mean?) paid for the tuition,the burden in every separate family is ( will be) alleviated.
it is undoubted that
what a wide range of vocabulary you have!!
Good luck
