    教学过程
    一、导入(lead-in)
    教师展示一些交通工具的图片,让学生比较它们的快慢。
    说明:复习词汇,同时为 3a环节做好铺垫。
    教学Grammar focus
    take 是初一下学期出现的一个很重要的动词。它的本义是“ carry sb. / sth. from one place to another ”,即“携带、运载”。但灵活的它在不同的场合有不同的含义。本单元涉及到它的两个用法,总结如下:
    1. take 表示“乘、坐”某一交通工具。如:
    My father usually takes a bus to work. 我爸爸常乘公共汽车去上班。
    Which bus do you often take? 你经常乘哪一路公共汽车?
    注意: take 和 by 都有“乘、坐”之意。 Take 是一个动词,后面接具体的交通工具,且在表示该交通工具的名词前一般应有冠词等修饰语;而 by 是一个介词,它后面所跟的表示交通工具的名词前一般不可用冠词等修饰语。 by 短语在句中修饰动词等作状语。如:
    格林先生经常乘火车去上班。
    Mr. Green often goes to work by train.
    Mr. Green often takes a train to work.
    2. take 表示“花费时间”之意,其常用句型为“ It takes sb. some time to do sth. ”,意为“某人花多少时间做某事”,注意后面的动词前的 to 不可丢掉。如:
    It takes her twenty minutes to walk to school every day. 她每天步行去上学要花二十分钟的时间。
    It takes me half an hour to do my homework in the evening. 晚上我要花半小时做作业。
    三、教学SectionA-3a

    …
    2.教师接着说,T: Great! Now open your book at the page 21. I’ll ask one student to read it to the class.
    3. 学生先自己阅读这段文章,然后让学生依次翻译一句,并将重要的句子和短语划出。
    4.最后教师说, T: Now let’s read it together and answer the questions.
    说明:对于学生翻译和朗读中出现的错误,教师要及时指正。
    四、教学Section A-3b               
    1. 教师指着这些图片说:Look at the pictures on page 21. Can you name each form of transportation?
    2. 学生回答完,教师接着说: Read the time and distance that goes with each form of transportation. Pay attention to “mile”, which is a common measure of distance in some western countries. (1 mile=1.6 kilometers).
    3. 教师让学生读出方框内的对话模式。
    4. 教师引导学生用图片中的信息与同伴编对话,叫几组将对话表演出来。
    例:
    五、教学4 Talking and writing

You ask each other questions to learn information for your chart, and then write the answers on the chart in your book. Don’t look at others’ pages please.
