Couldyouexplain“Thenwesortthemsothattheycanberecycled”?
对于本课出现的定语从句和情态动词的被动语态,老师只要让学生理解句子意思即可,不要求深度解释。
为了让学生便于理解,老师可以简单地用“把”字句和“被”字句来解释被动语态。

并列句是本课的学习重点。
老师如果觉得用英语讲解学生难以弄明白,不妨就用汉语表述。
但是“compoundsentence,conjunction”这些术语要学生能听懂才行,学生以后会经常听到。
老师最好将所举的例子板书出来,以加深印象。
老师可以自己(最好让学生)做动作同时辅以构词法来讲解:
agree(v)+ment=agreement(n)dis(不)+agree(v)+ment=
disagreement(n)。
