五年级下册英语Unit2教案
一、词汇要求(Topic vocabulary)
dropped picked up carried smelled smoke saw a fire shouted for help lost my walled found it gave it to police
二、语言知识要求(Language focus)
学会一下表达方式:
What do you do?
I helped someone today. What happened?
A lady dropped a bag. I picked it up and carried it for her.
三、语言功能要求(Functions)
1.当我们讲述一件过去发生的事情或说明在过去发生的一个动作时,通常用“一般过去时”来表达,而句子中的动词也要变成过去式,如I played basketball yesterday.
2.当我们想知道发生了什么事情时,可以问:What happened? 回答时也要用过去时的句子。 如: A lady dropped a bag, I picked it up and carried for her.
3.一般来说,动词变成过去式有以下几种情况:
(1)直接加ed,如look-looked。
(2)以不发音的e结尾的单词,直接加d,如live-lived。
(3)以辅音加y结尾的单词,把y变成i再加ed,如carry-carried。
(4)重读闭音节的'单词,双写后面的字母再加ed,如stop-stopped。
(5)有很多不规则动词的变化,需要我们牢记的,如 see-saw , go-went , fly-flew , swim-swam , come-came.
