英语中的从句指哪部分?包括连词吗?
When she was 12 years old,she began to live in Dalian.
从句指这个有连词的When she was 12 years old还是she was 12 years old

答案

When she was 12 years old是.这是一个状语从句,When she was 12 years old在这里做状语,she began to live in Dalian是主语,状语强调主句中动作发生的时间.从句一般由引导词引出,状语从句一般由when（时间状语）、if（条件状语）引导,定语从句一般由关系代词that、who、whom、where、which等引导.
