八年级英语师生共用导学案 Unit 6 Topic 1 Section A 一．读1a, 回答问题 1. What are they going to do for their spring field trip?___________________________________ 2. How would Jane like to go there?__________________________________________________． 二、在文中划出下面的句子并翻译 1. I have some exciting news to tell you! 译：__________________________________________ 在此句中动词不定式to tell you作名词news的______语。
练习：1. I have a lot of homework______________ (do). 2. Do you have anything important _________ say? 2.. We are going on a three-day visit to Mount Tai. 译：______________________________________________ 点拨：three-day是复合形容词，作定语修饰名词visit. 类似的用法有 a four-year-old boy ; a two-day holiday 注意区分复合形容词three-day与名词短语three days. 复合形容词three-day, two-month, four-year-old 等只能作定语修饰名词。
练习：1. He is only ____ ___________ ______(三岁的男孩). Don’t be too strict with him. 2.There is a _________________________(10米宽的) river in front of the village. 3. It will take us a few days to get there by bike. 译：____________________________________ 点拨: 此句中it是_________主语。真正主语是________________________. 请记住句型It takes sb.some time to do sth. 做某事花费某人多长时间 练习:1.昨天做作业花了我两个小时。It _______ ______ two hours ______ _______my homework yesterday. 链接：somebody+ spend some time doing sth 某人做某事花多长时间 1.昨天做作业花了我两个小时。I _________ two hours ___________ my homework yesterday. 4.Let’s make the decision together. 译：__________________________________________ 回忆：decide 是_____ 词，决定做某事 decide __________________. decide on sth decide 的名词形式_________________， 相关词组：make a decision 译：做出重要的决定__________________________________ 5.It’s too far to cycle. 译：________________________________________ 点拨：1.）Ann太小了，不会读书。Ann is ____________ ___________ __________ ___________books. 链接：so---that 译：_________________________ 1.）Ann太小了，不会读书。Ann is _________ young _________she __________ read books. 6. Let’s find out some information about the cost.译：____________________________________ 点拨: 区分find与 find out: 1）find 找到，发现。有偶然发现某物的意味。例如：He found a wallet lying on the ground. 2）find out 找到，发现，查明，多指通过调查询问研究之后“搞清楚，弄明白”。
例如：
Please find out who took my book by mistake. 练习: 用find, find out 填空并翻译：
1）I looked for my keys everywhere, but I couldn’t ________ them. 2) He wants to _______ ______ the truth about what happened. 7. Helen, your task is to find out the cost by bus. 译：_________________________________________________ 点拨：此处的 to find out the cost by bus 在句中作_______语。
例：我的工作是每天打扫教室。My work is ___ __ ________ _______ ____________ every day. 四．语法重点 动词不定式 (请大家先认真预习课本123页动词不定式的语法部分) 1. 作主语：
动词不定式作主语时，常用it作形式主语，而将真正的主语放到句末。
其结构为：It +is+adj.+（for/of）+动词不定式 例：To speak loudly in public is impolite. 或 It is impolite ____ ________ ________ in public.. It is impolite for us to speak loudly in public. 区分It is adj. for sb. to do sth. 与 It is adj. of sb. to do sth. 1) for 的意思是“对于”，当要说明动词不定式的动作对于某人是怎么样的，用It is adj. for sb. to do sth. e.g. It’s difficult for us to finish the work. 2) 如果形容词是kind, nice, right, wrong, good, clever, polite, careful, careless, foolish等描述行为者本身的性格，品质的形容词时，用It is adj. of sb. to do sth. 1.It’s very kind of you to help me. 你帮助我真是太好了。= You are kind to help me. 2. 作定语：动词不定式作定语要后置。
e..g. I have a lot of clothes to wash. 我有很多衣服要洗。
此处逻辑上的动宾结构为wash clothes. He wants to find a chair to _________ ___________. 他想找把椅子坐。
I need a piece of paper to __________ __________. 我需要一张纸来写。
3. 作状语 1）作目的状语 He ran so fast ________ __________ the first bus. 他跑这么快是为了赶上第一趟车。
2）作结果状语 They were __________ _________ __________ say a word. 他们太激动了，以至说不出话来。
3）
作原因状语 She cried _________ _________the news. 她听到那消息哭了。
观察：观察下列section A 中的句子，划出动词不定式部分并思考它在句中充当什么成分,然后翻译句子。
1. There are other vehicles for us to choose. 作____语 译：_________________________ 2. Do you know the best way to get there? 作____语 译：__________________________ 4.作宾语 例：He refused to help me. I hate to go to the hospital. 5.作宾语补足语 例：Michael teaches me to study American culture. 6.作表语
