That’s what makes him famous...（那就是使他出名的原因） 这是一个 表语从句（what引导的从句作is的表语）。what makes him famous 整体作名词性成分，意思是“使他出名的事情”。make + 人 + 形容词 表示“使某人变得……”。 例句： That’s what I want to know.那就是我想知道的。 Hard work is what makes him successful. 努力工作是使他成功的原因。 His kindness makes him popular. 他的善良使他受欢迎。 5 It must be a lot more convenient to travel in cars than on horses.

Find out more information about the inventions that you’re interested in, and then introduce them to your group members.

That phone, the Motorola DynaTAC, weighed over 1 kilogram and offered just 30 minutes of talk time.
