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 isn't a worker any longer/any more. He’s an engineer now.
2) He no longer lives here. = He doesn't 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.We'd 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 won't 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 won't 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。
