Step4:presentation

（一） 1、Play the tape and let the students listen. 教师播放录音.

2、There are so many flags in the UN. Many countries are in the UN. The UN wants to make peace in the world.

3、找出含有 want to 的句子并分析其规律。出示这3句含有want to的句子，观察这三句话有什么共同之处。会有学生发现want to 后面接动词原型。

教师总结：want to 后面要接动词原型，如want to play, want to eat.让学生说几个想做什么事的词组。

4.再问：发现want to有什么变化吗？

The UN wants to make peace in the world.中want加了s。请学生思考为什么。帮助学生总结，主语是第三人称单数形式时，用一般现在时表述想做什么事，动词也要变成第三人称单数形式。如Amy wants to go to Beijing.让学生尝试说两句。

5. Listen and answer:

A.Is the UN building small?What is the present ?

How many flags are there?
