翻译错误不少:Although we have encountered some trouble and risk in the course of our advance successfully solved.有从句,没主语,没主句; trouble换成difficultiesAlthough we encountered some difficulties and risks in the course of our advance, we have successfully solved them.建议用现在完成时, keeped应该是keptWe not only have not caused social unnrest but have also greatly liberated and developed social productive forces and kept social stability and overall development.
