三个表达都是正确的.The new workers are young and inexperienced.They are eager to learn from the veteran workers.这是使用了两个独立的句子表达
Young and inexperienced,the new workers are eager to learn from the veteran workers.
这个里面的“Young and inexperienced ”是形容词做定语,定语前置,修饰主语the new workers
The new workers,who are young and inexperienced,are eager to learn from the veteran workers.这个句子里面使用了一个定语从句
以上三句的意思一样再请问一个问题：Once thought to be Egyptians, the gypsies are really a nomadic people from India, who migrated into Europe. 中Once thought to be Egyptians做句子的什么成分？吉普赛人曾经被认为是埃及人 是过去分词短语作为定语
