1.他十三歲開始給地主干活，一直到解放。He began to work for a landlord when was thirteen years old until liberation.請問，為什么要加“when”???

他十三歲開始給地主干活，一直到解放。He had been working for a landlord when he was thirteen years old until liberation.until 的句型中要用延續性動詞，所以改成had been working ，when 后不能省略主語he,

熱心網友

這里的"when"是引導一個時間狀語從句，如果去掉的話會導致句子成分的殘缺，

began to work for a landlord 和 when was thirteen years old 共用一個主語"he",全句完整可看作:He began to work for a landlord when he was thirteen years old until liberation .

搞錯了吧,本來全句應是:He began to work for a landlord when HE was thirteen years old until liberation.省略哪有只省略he的?或者簡單些He began to work for a landlord from thirteen until liberation.

"When" is to modify "he"The sentence should be written as, "He began to work for a landlord when he was thirteen years old until the liberation." However, you can ingore the "he" after "when" since it is repeative.

liberation是中國1949年解放的專有名詞，要加the并且開頭字母大寫。而且建議加when，聽著舒服。

不加的話句子不通啊！除非說he began to work for a landlord at 13 until liberation.
