How can I answer the question "你什么时候开始学中文的?" I cannot answer the "什么时候" questions. Can anybody help me please?
'什么时候' = 'what time' = 'when'
You can answer with one of the following:
[Since the time of ]. E.g. "Started since 2016" (從 2016 年開始)
[from a length of time ago]. E.g. "Started from five years ago" (五年前开始)
A: "我是從2016年開始学中文的"/ "我是五年前开始学中文的" (long version)
A: "從2016年開始"/ "五年前开始" (short version)
A: "2016"/ "五年前" (shortest version, just state a year or a length of time ago)
More example of '什么时候' question:
A: 晚上七時 (a time) If the question is about what is the regular time you have dinner'
A: 三小時前 (a length of time ago) If the question is about what specific time you ate your dinner tonight
