　　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: It's 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: It's nearer. It's 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: It's 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

anywhere

nobody

no one

nothing

nowhere

　　然后告诉学生这些词都是由some，any或no与body，thing，one或where构成的合成词，一般情况下，somebody, something, somewhere用于肯定句，而anybody, anything, anywhere用于否定句、疑问句及条件句中。如：
　　(1)I can see something on the wall. Is it a new painting?
　　(2) Somebody is knocking at the door. Go and have a look.
　　(3) Yesterday Han Mei found her pen somewhere. Now she still doesn’t know who put it there.
　　(4) Can you hear anything in the next room? Somebody is crying.
　　（5) –Is there anybody running on the playground?
　　　　–Yes, it’s Wang Tong.
　　(6) I can't see anybody in the teacher's office. But I must ask the teacher an important question.
　　(7) They didn't go anywhere, because it was raining heavily. They played ping-pong in the classroom.
　　但也有例外情况。当表达请求、建议、反对等肯定意图时，something, somebody等词也可用于疑问句形式。如：
　　(8) – Is somebody coming this evening?
　　　　–Yes, But I don’t know who’s coming.
　　(9) Would you please give me something to eat? Certainly. Help yourself to anything in the ice box.
　　教师可通过实物教学或创设情景教学，让学生在情景中学习并掌握不定代词或副词的运用。如教师可利用教室中的物品：box, bag等进行活动。

　　A: Can you see anything in the box?
　　B: No, I can’t. It’s closed.
　　C: I think there is something in it.
　　B: I don’t think so. Let’s open it. Maybe there’s nothing in it.
　　还可以出示图片假设情景：孩子们在春游，看见远处树丛中树叶晃动。

　　A: Look! Can you see anything over there?
　　B: No, I can’t see anything.
　　A: Nothing? Look carefully and you’ll see something in the trees.
　　B: Sorry I can’t. Something is wrong with my eyes.
　　A: There’s nothing wrong with your eyes, I think. Look again and you’ll see it.
　　B: Oh, yes. Something is moving in the tree. It’s a yellow bird!

　　巩固性练习：在学生了解不定代词基本用法的基础上指导学生做练习册第87页上的练习2，教师也可以适当补充一些课外练习来进一步加以巩固。

教学take和bring的用法
　　take和bring都有“拿”和“带”的意思。学生在实际运用中容易混淆。一般来说take是把东西拿到离开说话人所说话的地方。表示“拿走”或“带走”。而bring则表示把东西拿到说话人所说话的地方，是“拿来”，“带来”的意思。用图表示：
