以下的是定语从句吗?
1.He's answering the telephone becauws the receptionist who usuallyanswers it is at the dentist's office.是定语从句吗?为什么用who?it代表什么?
2.He's typing letters because the secreary who usually types them si at home in bed with the flu.是定语从句吗?为什么用who?them是什么?

Answer 1

1 他正在接电话,因为通常接电话的接待员正看牙医.
who usually answers it 是定语从句,其先行词是名词the receptionist ,从句中用who来指代人
it指前文提到的telephone
2 他正在打字,因为日常打字的秘书因患感冒卧病在床.
道理同上.who指代先行词色彩让他人“秘书”,them指代前文提到的letters
