过去时的被动语态。
was/were+pp
通过复习一般现在时的被动语态来过渡到一般过去时的被动语态。
以旧引新、比较学习能让学生更快地掌握新知识。
一定要把学生说出的被动语态的句子板书出来，为后面的教学作准备。
如果学生能正确地表述过去时的被动语态，老师直接板书，如果不能，老师要引导学生总结出来。

It’smadeofwood
It’susedforputtingcomputerson.
这个部分分成两步骤来完成较好。
第一，帮助学生区分bemadeof和bemadefrom的用法。
第二，如何运用介词。
理解这两点，有利于学生构建对话。
学生不能解释清楚的老师要补充。
老师在此过程中，顺便解释：
lock。
为了简单明了，老师可以用汉语解释，因为涉及到不少术语，学生难以听懂。
