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3.Each question is worth one point. 每一個問題值一分. worth adj.值……的; (只能用來做表語)。E.g. This film is worth seeing twice. 這部電影值得看兩遍。 That mobile phone is worth 2000 yuan. 那部手機(jī)值2000元。 I don’t think it is worth so much. 我認(rèn)為它不值得那么多錢。The problem is worth notice. 這個問題值得注意。 **** worth與worthy adj.的用法對比: be worth doing = be worthy of being done = be worthy to be done; Contrast: E.g. This book is worth reading. = This book is worthy of being read = This book is worthy to be read. 這本書值得一讀。**** worth只能用well來修飾, 不能用very。
