Pre-reading: Step One Preview预习单词及短语 Step 1: Learn to read the words
1. Ask the students to read the words by themselves using the phonetics and underline the difficult words, such as volunteer, satisfaction, journey, imagine...
2. Encourage the students to read the difficult words with their partners.
3. Get two or three students to read all of the words. Ask some other students to correct the pronunciation as possible as they can. If necessary, the teacher corrects them. 4. Read the words after the tape and imitate the pronunciation.
5. The students read the words aloud themselves while the teacher walks around the class to see if the students have any questions.
[操作说明] 首先由学生自己根据音标识读单词，并标划出识读时有困难的单词。鼓励学生以两人一组为单位解决有困难的单词。接着找两三个同学读单词，如果有发音错误，请其他学生先纠正，必要时，教师再更正。然后让学生跟录音读，模仿发音，最后学生再自由，教师解决学生可能遇到的问题。
【设计意图】该步骤能有效培养学生个人识读单词的学习习惯，这是学习单词的重要一步；能培养学生自主、探究和合作学习的能力。 Step 2 : Remember the words
