本句为主从复合句。Taking it as an object of study为动词-ing形式短语作状语；that引导宾语从句。 Period 5　课时练案 课文整体教学(Developing ideas) Today，the action of sharing takes on⑦ extra meaning.It's not just about sharing sweets or frustration⑧； it has expanded to almost every aspect of our lives—the whole world seems to be into sharing.We are using technology to reduce the money that we spend on goods and services，or to make money out of those that we don't use ourselves all of the time.These vary from car shares to⑨ home shares，and even to pet shares.The sharing economy is taking off ⑩ in all sorts of areas.It is
