　　1.鲁迅是作家周树人的笔名，生于1881年，其家庭有深厚的儒家背景：“笔名” 可译为penname。句中的“有”可用with来翻译，所以“有深厚的儒家背景”就是：with a deepConfucian background。

　　2.因此，鲁迅在1906年回到东京，决定放弃医学，投身于教育和文学事业：“投身于”可译为devote oneself to,devote意为“投身、贡献”。

　　3.毛主席称他为“中国文化革命的主将”:“称”可译为call, call可以跟双宾语，常用表达是call sb. sth.“中国文化革命的主将”可译为commander of China’s cultural revolution。
