Question

如何分析英语句子的结构和成分，句子如下？

Computer makes it possible for people to talk face to face even if they are in different parts of the world, which has entirely changed our life.

Answer 1

Computer——主语
makes——谓语
it——形式宾语 指不定式 to talk face to face
possible——形容词作宾语补足语
for people ——介词短语作状语，表对象
to talk face to face ——不定式作真正的宾语
even if——引导让步状语从句
they are in different parts of the world——让步状语从句
which has entirely changed our life.——非限制性定语从句（和前面的句子之间有一个逗号隔开）which是引导词。该从句去掉的话，对主句的意思不影响。
