句3：在与印度和中东(theMiddleEast)的交流中，在他们的促进下，唐朝在许多领域里得到了长足的发展。
“与印度和中东(theMiddleEast)的交流中，在他们的促进下”可采用合译法，即Stimulatedbythecontactwith…StimulatedbythecontactwithIndiaandtheMiddleEast,theempiresawagreatdevelopmentinmanyfields.
译：TheTangperiodwasthegoldenageofliteratureandart.
句5：唐朝通过科举制度(civilserviceexaminations)在全国选出优秀的儒家文人(Confucianliterati)为政府效力，而唐朝的政府体系在儒学官僚(Confucianbureaucratic)的支持下也日臻完善。
此句结构较为复杂，翻译时，首先理清句子主干：唐朝的政府体系日臻完善。前半句可以处理成一个非谓语动词做原因状语的形式，即Servedby…,serve本意为“服务”，也可作“效力”讲，与逻辑主语thegovernmentsystemofTangDynasty是动宾关系，故用过去分词形式;而其中再嵌套一个后置定语selectedthrough…来修饰Confucianliterati;“在……的支持下”译为underthesupportof…。
