教学建议
教学内容分析
本单元的教学核心是关于孩子们参观小岛（A visit to an island）的这件事。围绕这个核心安排了三个对话和两篇短文，集中反映了孩子们上岛前所做的准备工作（约会、带食品、约定出发的时间，讨论去哪一个岛等）及在岛上的所见所闻，情节跌宕起伏，有一定的传奇色彩。在整个内容的安排中引出了本单元要学习的功能项目“推测”（Conjecture）、求助（Calling for help）和动词take，bring的区别及不定代词和不定副词的用法。
在第73课中有两段对话，主要描述孩子们在上岛前所做的准备工作及讨论去哪一个岛。从而引出英语中表示距离远近的表达法。如：Why don’t we go to the farther one?/ How about the farthest one？/The smaller one is nears．这两段对话为下节课做了内容上的铺垫。
第74课和第75课的第一部分及第76课的第一部分事实上是一个故事的整体，具体描绘了孩子们在岛上的所见所闻，表现了孩子们新奇、紧张、害怕交叉在一起的复杂心情。第76课中关于一群猴子企图偷吃篮子里食物的一段描写颇为生动。第75课的第二、三部分着重练习不定代词和不定副词的用法。第76课的第四部分是提示性的写作训练。主要是对课文的模仿和对所学内容的实际运用。教师可以作一些适当的解释。第五部分是一首小诗。
重难点及疑点分析
重难点：
1. no longer= not any longer, not any more. no longer与系动词be连用时置于系动词be的后面，与行为动词连用时放在行为动词的前面，如：
1) He is no longer a worker. = He isnt a worker any longer/any more. He’s an engineer now.
2) He no longer lives here. = He doesnt live here any longer/any more. He’s living in another city.
2.There’s something wrong with your ears.
There + be + something/nothing wrong with. . .是一个固定的句型，意思是“…出/没毛病（问题）。它的同义句是Something/Nothing + be wrong with. . .如：
1) There is something wrong with your computer. = Something is wrong with your computer. It’s not working now.
2) There is nothing wrong with the new bike. = Nothing is wrong with the new bike. It’s quite OK.
疑点：
1.短语too…to
too…to句型的意思是“太……以致不能……”，too是副词，后面接形容词或副词，to是动词不定式的标志，后接动词原形。该句型虽然没有否定词not或no，但具有否定的意义。若需要加上人称，则在不定式之前加for sb。如：
1) The sentence is too difficult to understand. Please give me an easy one.
2) These apples are too high for us to reach. We’d better get a ladder.
2.Wed better not go there. It’s too far from here.
had better后面接动词原形，其否定形式是had better no+动词原形。had不受人称限制，不可以说have／has better。如：
Girls had better not go out at night. They had better stay at home.
2. We’ve never been there before.
该句型 have; has been to+地点名词表示某人曾去过某地，现在已离开那个地方或已回来。若地点是副词则“to”省略。如：
We have never been to Shanghai. But they have been there for three times. They can tell us a lot about Shanghai.
3. We wont go until we get it back again!
本句中的until作连词，引导一个时间状语从句。not…until意为“直到……才”，“在……之前不……”，主句中的谓语动词一般是非延续性动词，如leave，finish，begin，go，start等，until引导的时间状语从句中将来时用一般现在时表示。如：
They wont leave their school until their teacher returns. They will ask the teacher many questions until they are able to do these exercises.

口语训练
本单元的口语训练主要包括两项内容①表示距离远近的用法。②不定代词和副词的用法。
1．表示距离远近的用法
在学生熟练掌握第73课第二部分内容的基础上，先回忆一下以前学生用书中所出现的一些有关距离的表示法。如How far is it？/ Is it far？/ It’s/quite near．／It’s about…kilometers farthest（furthest）等。同时复习一下far这个词的不规则比较级形式和最高级形式。far→farther（further）→farthest（furthest），告诉学生near（close）的比较级和最高级形式的变化是规则的。老师可以给学生一些提示，让学生相互之间展开由易到难的练习。
（1）编制一些简单的问句问学生。如：
How far is it from your home to school? Is it near from your home to your uncle’s? Is our school far from People Park? Where’s the shopping center?等。
（2）编制一段对话。如：
Lucy: Hi, Li Lei! Where are you going this summer holiday?
Li Lei: My father will take me to Nanjing.
Lucy: How wonderful! Nanjing is an old but beautiful city. How far is it from here?
Li Lei: Its about 360 kilometres. What about you?
Lucy: I’m going to Shanghai with my uncle to see my grandfather. He works there.
Li Lei: How far is it from here? Is it nearer or farther than Nanjing?
Lucy: Its nearer. Its about 180 metres.
A: Which city do you like best, Qingdao, Nanjing or Hangzhou?
B: I like Hangzhou best.
A: Is Hangzhou near here?
B: No, It’s far from here. It’s about 210 kilometres away.
A: What about Nanjing?
B: Its farther. It’s 600 kilometres away.
A: And Qingdao?
B: It’s the farthest. It’s nearly 1000 kilometres away.
2．不定代词和副词的用法
在第74课及第75课中出现了不定代词和副词的用法。在第75课中更为集中，首先对一些不定代词作一些归纳。列表如下：
somebody
someone
something
somewhere
anybody
Anyone
anything
