【正确答案】 1、正确答案：In the mid-19th century, Western powers forced China"s door open with gunboats. Since then, domestic trouble and foreign invasions gradually turned Chinese society into a semi-colonial and semi-feudal one. The country became poor and weak, and the people could hardly survive in the chaos caused by wars. At that vital time when the nation"s existence was in peril, numerous patriots one after another fought very hard to find a way to reform and save it. The Revolution in 1911 put an end to the system of monarchy which had ruled China for several thousand years, and inspired the Chinese people to struggle for national independence and prosperity. However, such efforts and struggles failed to change the nature of China as a semi-colonial and semi-feudal society, or help the Chinese people out of plight. Living up to the people"s expectation, the CPC led them in carrying out arduous struggle, and finally founded the People"s Republic of China in 1949. This marked the realization of China"s independence and liberation of its people and ushered in a new epoch in China"s history.
