There are some. There are no. pond A pond B 九教学反思： 本节课上下来，整体感觉比较顺利。教学设计中的教学目标基本达到。学 生能够很好的掌握本节课的重点单词和句型。通过学生的听说读写能力均得到 了练习。课堂评价与本本课内容紧密相关,虽然pond是新单词,但在一开始,就 已经渗透在教学中。There be句型操练扎实,学生掌握较好。课堂生成方面比 预期要好,原以为学生只能按照我给出的句型来描述,但实际上,学生做到了从 正反两个角度来描述。如:The pond is clean.There are some fish in the pond.There are no trash in the pond.由此可以发现,学生真正学会,学懂 了,而且能够灵活运用。 不足之处是，时间没有把握好,写的训练时间比较紧张,每组只完成了一道 题。
