一、教法建议
【抛砖引玉】
　
本单元主要内容：（一）复习一般现在时；（二）专有名词的使用；（三）生词及习语。本单元知识点多而杂，但都很重要，而交际部分与日常生活比较密切，因此，应多创设语言环境。在课堂上，应以对话、问话为主。每讲一个知识点时，应配合一个例子，测试学生的反应力、接受力及创造力。使学生在语言环境中，领悟到语言的功用及魅力。
　
【指点迷津】
根据本单元知识点多实用性强的特点，应多用举例法和联想法激发学生兴趣。
（一）本单元难点：1.复习一般现在时。2.专有名词的使用。3.新词汇及习语的记忆4.本单元知识点：

（二）解决难点的关键:结合本课知识点多而杂的特点，要通过各种简单易懂的例子，使学生在教师的指导下模仿例子，然后让学生造出新的例句。
　
二、学海导航
【学法指要】
为了帮助学生巩固本单元所学知识,精选以下几道不同类型的题目,仅供参考。
1.How______do you want ? Ten kilos.
A.much rice B.many rice C.much rices D.heavy rice
【提示】四个选项很接近，关键要明确rice是不可数名词,这样答案就不难选了。
【答案】A
2、_______moon goes around the earth ,and the earth goes around_______sun .
A、The…不填 B.不填…the C.不填…不填 D.The…the
【提示】定冠词the用于表示世界上独一无二或被视为整体的东西的名词前。例如： the sun,
the moon， the earth， the sea，the land，the sky， the weather。
【答案】D
3、Open the window!_______is nice and clean.
A、Today air B.Air of today C.Air today D.The air today
【提示】 today作后置定语修饰air , air前要加定冠词the.
【扩展】The air today is nice and clean.意思是:今天的空气非常／很清新。英语nice and和good and同样是一个习惯用语，用在形容词之前加强语气,其含义是very (很、非常),实际上就是一个偏正结构,nice and对后面的形容词起了修饰作用。
例如： I was good and hungry.我当时很饿。
【答案】D
4.We often_______(clean )our classroom after school.
【提示】一般现在时表示经常性、反复性和习惯性的现时行为。当句子主语为除第三人称单数外的其他人称时（一、二人称单数及复数各人称），一般现在时的构成为动词原形。由于一般现在时所表现的是现时行为的三性（经常性、反复性和习惯性），所以常用的时间状语有：often，sometimes， every，usually，always， normally等。
【答案】clean
5.Who_______(watch)TV every day? Do you know?
【提示】首先看时间状语，判定是一般现在时。然后，判定用watch还是watches,在不知道是谁的情况下，一律用单数。
【答案】watches
6.What time do the students have lunch?(用Tom改句子)
【提示】完成本题关键在于要明确一般现在时的构成：
①主语+谓语+宾语+状语；
②当主语是一、二人称或复数人称时，谓语动词不变；
③当主语是单数第三人称时，谓语动词要变化（+s或es），如变此句为一般疑问句用does，然后谓语动词恢复原形。
【答案】What time does Tom have lunch?
7.“_______do they get there?”“By air.”
A、What B. Where C. How D. Which
【提示】By air意思是by plane，译作乘飞机。对by air进行提问,在四个选项中只有C是对的。
【答案】C
　
【妙文赏析】

He doesn't think it's necessary (必要的)to know some knowledge(知识)of science .His son, Bill, began to go to school last year. The boy likes nothing except playing.

Mr Brow had to do as his wife said. The next afternoon Bill came back and showed his exercise-book to his father. The man had a look at it and shouted to his wife,“ come here quickly ,dear ! I got an A in maths!”
【思路点拨】
1.第一句就告诉读者，Mr Brown was born in a poor family ,接下来讲，He couldn't go to school .就是说Mr Brown未能上学是因为他家境贫寒。
2、在文章中指出：The boy likes nothing except playing,这就是他无法完成作业的最主要原因。
3、Their son, Bill ,began to go to school last year.从这句话可以看出Bill还不到十岁，像这么大的孩子，哭泣大都是为了一些小事。
为了帮助学生更好地理解本篇文章，可设计三个问题：
1.Which of the following is true?
A. Mr Brown was going to be a porter when he was young.
B. Mr Brown's parents were too poor to send him to school.
C. Mr Brown wasn't interested in science when he was young.

【分析】
首先明确1英磅应是an English pound, 1美元应an American dollar,然后根据自己的课外知识，来判定哪个选项是对的。
【答案】A
三、智能显示
【心中有数】
本单元重点：一般现在时和专有名词的使用。在各级各类考试中，一般现在时是必考时态，而专有名词偶而出现。

lunch午餐 supper晚餐
2.下面所给的图形,均表示动作的不同频度。按照所给示例写出其它频度副词。
