互動封閉仿真課堂
1、智能交互 2、電子板書式視頻教學(xué) 3、在線互動問答 4、封閉課堂啟發(fā)式教學(xué)方式
隨堂測試、知識梳理、易錯點揭示、總結(jié)啟迪智能錯題本
聽課中的錯題能自動加入錯題本,課后可方便復(fù)習(xí)及導(dǎo)出錯題本升級服務(wù)
在線答疑、課后同類題練習(xí)、講義下載、短信提醒“介詞 關(guān)系代詞”可以引導(dǎo)限制性定語從句,也可以引導(dǎo)非限制性定語從句。這個結(jié)構(gòu)中的介詞可以是in, on, about, from, for, with, to, at, of, without等,關(guān)系代詞只可用whom或which,不可用that,且介詞后面的關(guān)系詞不能省略。另外某些在從句中充當(dāng)時間,地點或原因狀語的“介詞 關(guān)系代詞” 結(jié)構(gòu)可以同關(guān)系副詞when和where互換。
eg: This is the house in which my mum and I used to live.
