隨堂測試、知識梳理、易錯(cuò)點(diǎn)揭示、總結(jié)啟迪智能錯(cuò)題本
聽課中的錯(cuò)題能自動加入錯(cuò)題本,課后可方便復(fù)習(xí)及導(dǎo)出錯(cuò)題本升級服務(wù)

關(guān)系代詞在定語從句中用作介詞賓語時(shí), 介詞可放于從句之首, 也可放于從句之末. 但以放于句首較為正式.(介詞前置,必須注意不影響動詞詞組的含義。關(guān)系代詞who 和 that 用作介詞賓語時(shí), 介詞必須放在句末.)如:
1. This is the book for which you asked.
=This is the book (that/which) you asked for.
2.Do you know the person with whom I shook hands?= Do you know the person (whom/who/that) I shook hands with?
3. The beginning of agriculture was a big step in human progress with which nothing could compare until our information age.
