第一课时
module 1
step 1
1. 用 powerpoint 制作,插入一张电灯泡的图片,依据讲课内容,旁边依次闪现 light bulb, invent, thomas edison, 1879.
2. t: look at the picture on the screen.
what's that in english?
ss: ...
t: it's a light bulb. (students read “light bulb” after the teacher repeatedly.)
t: who invented the light bulb?
thomas edison invented the light bulb in 1879. (屏幕上,在图片的下面出现这句话。the teacher explains “invent” to help students learn the new word. “invent” means “to make, design, or think of a new type of thing”. students read “invent” after the teacher again and again.)
step 2
1. 邀请5名学生做个排序游戏:教师将事先准备好的大卡片随意地发给4名学生,每张大卡片分别印有 the light bulb, thomas edison, in 1879, invented。让他们自己排序,手持卡片、面朝大家排队。
2. t: is it right, class?
ss: yes/no.
3. 5 号学生做助手帮忙,找到正确的顺序,并大声朗读,其他学生集体跟读。
step 3
1. 教师特意地颠倒 “the light bulb”和 “thomas edison”的顺序。
2. t: can we say like this?
ss: no.
t: we can say in another way in english.
3. 教师手拿印有 was 和 were 的两张大卡片站在 invented 的前面,要求5号学生手持 by 插入 invented 的后面。教师分别用 was 和 were,要求其他学生朗读,判断用 was 还是 were. claps for them! 5 名学生回到座位上。
4. 板书说明
被动语态的构成:助动词 be + 及物动词的过去分词
was/were + 如:invented, called, allowed, done 等
t: 英语动词有两种语态,即主动语态和被动语态。主动语态表示主语是动作的执行者,被动语态表示主语是动作的承受者。被动语态的助动词 be 有人称、数和时态的变化,其变化规则与 be 作为连系动词时完全一样。本单元主要学习一般过去时的被动语态。
5. 要求学生看屏幕,重复用被动语态的表达方式。教师点鼠标,在最下方出现
the light bulb was invented by thomas edison in 1879.
t: 当我们不知道谁是动作的执行者,或者没有必要指出谁是动作的执行者,或者只需强调动作的承受者时,要用被动语态,删除 by 引出动作的执行者。如屏幕显示:
the light bulb was invented in 1879.
module 2
step 1
1. 切换两张电话和多台计算机的图片,旁边分别出现提示词 bell, 1876和1976, personal computers.
2. t: talk with your partner about the invention with the words given.
完成任务所需要的语言结构:
① what is that/are they? it's/they're ...
② ... was/were invented by... in...
3. ask a few students to say.
4. 图片下面呈现正确的说法:
the telephone was invented by bell in 1876.
the personal computers were invented in 1976.
学生重复朗读,注意句中不同颜色的标注。
step 2
1. t: list your favorite books, songs, movies, tv shows and so on.
