To get a full appreciation of what this means we must turn first to some recent human inventions.
能详细一下各个成分么
追答To get a full appreciation of what this means 这是目的状语,TO引导目的状语从句,这个你应该知道。
get a appreciation of,这个是个短语,做从句的谓语。
后面接从句的宾语what this means,同时这个又是个宾语从句。
后面是主句,we是主语,must turn to谓语,后面接宾语some recent ....。
你也太答非所问了???
