教材导读
1．- What are you going to do，Eddie?埃迪，你要去做什么？
- I'm going to exercise.我打算去锻炼。
探究点：“be going to＋动词原形”属于什么时态？和will有区别吗？这一结构可用于所有的动词吗？
[指点迷津] “be going to＋动词原形”属于将来时，表示“计划／打算／将要做某事”，强调事先考虑好或安排好的事情。
- What are you going to do tomorrow?
明天你打算做什么？
- I'm going to do my homework at home.
我打算在家做作业。
[知识拓展] “will＋动词原形”也表示“将要做某事”，一般可以和“be going to＋动词原形”互换，但“will＋动词原形”强调事先未经考虑或安排，不以主观意志为转移的事情。come，go，leave，arrive等表示位置移动的动词常用现在进行时表示将要发生的动作，它们很少与be going to结构连用。
He will be twenty years old next year.他明年就20岁了。
Miss Sun is coming tonight.今晚孙小姐要来。
用be going to或will填空
①It______________ be Sunday tomorrow.

③I _____________________ play basketball this afternoon as I planned before.
2．Well，this hill isn't as high as a real one!嗯，这座小山没有真的高！
探究点：it和one有何区别？
[指点迷津] it指的是与前面已提到的事物为同一物，此时的it等于“the (this，that，my…)＋名词”；而one指的是与前面已提到的事物为同一类物，此时的one等于“a＋名词”。

3. Come on, Hobo. Let's enjoy ourselves!

探究点一：come on在口语中常有哪些意思？
[指点迷津]come on常用于口语中，表示动员、激励别人做某事，意思是“快点；加油”等。
Come on! The bus is coming．快点！公共汽车来了。
Come on! You can win! 加油！你会赢的！
[知识拓展] come on在口语中还可意为“得了吧，别胡扯”。

好了，别胡扯了，你反正别指望我会相信那件事。
①来吧！让我们一起唱首歌吧。
_____________________! Let's sing a song together.
探究点二：enjoy oneself的意思是什么？如果跟动词用什么形式？
[指点迷津] 句中enjoy ourselves的基本结构是enjoy oneself，其中的oneself要根据主语换用合适的反身代词，意思是“玩得高兴，过得愉快”，相当于have a good/great／nice time或have fun。它们后面都可以跟现在分词短语，表示“做某事玩得高兴，做某事过得愉快”。
We often enjoy ourselves swimming in the river in summer.
＝We often have a good/great／nice time swimming in the river in summer.
＝We often have fun swimming in the river in summer.

5．- How wide is the bridge?这座桥多宽？
