中华人民共和国自从1949年就成立了,翻译成英语是什么?初中水准的,急

1楼的时态不对,最好改成:The People's Republick of China has been established since 1949。因为用一般过去时,不接since引导的时间状语。而用现在完成时,却能很好地表达句意。并且也能接since引导之时间状语。--------上面还有一个错误,就是establish是非延续性动词,不能用for/since引导时间状语。所以正确的是:The People's Republick of China has started since 1949。或者用一般现在时,The People's Republick of China was established in 1949。
