三、Presentation (学生或教师)

With some adjectives, we can change the meaning by adding a prefix(前

缀). Adding the prefixes “dis-”, “im- “in-” “ir-” or “un-” to an adjective will express the opposite meaning of the word. These prefixes mean “not” or “the opposite of” e. g. Trainers are comfortable to wear. Small shoes are uncomfortable. If someone shows good manners to others, he is a polite person.

If someone does not show good manners to others, he is impolite.

你可以再列举一些吗?

四、Practice

A.Match the adjectives on the left with their opposite on the right.( Part A)

B.Play a game .

每人准备好5张分别带有dis-, in- , im-, ir- un- , 前缀的卡片。每组选一名代表,

然后从余下的学生中挑选一位发令员,其余学生做裁判。比赛开始,发令员大声读出形容词,要求学生快速反应举起写有正确否定前缀的卡片。举错卡片或反应明显慢于其他选手即遭淘汰,直至淘汰到最后一人,该学生即为优胜者,其所在小组为优胜小组。 还可以按此方法做几轮游戏,各组累计总分。
