For example, when you show the word “train” on the screen, the student who has the picture of a train should stand up quickly and say “Im here!”)【教學(xué)設(shè)計說明】圖片教學(xué)法是呈現(xiàn)新知識最簡單有效的方法之一，學(xué)生通過圖片，能更價值觀的理解新單詞的含義。此環(huán)節(jié)重點(diǎn)在新單詞及詞組的意思和發(fā)音上，所以要盡量讓更多的學(xué)生張口說，必要的機(jī)械操練是必不可少的。3.
