Teaching Preparation: audiotape, flashcards, 教学过程：

Step1.Greet each other before the class. Step2知识超市

1. How tall are you? 你有多高？

how tall 意为“多高”，是询问别人身高的常用语。其结构为How tall + be + 主语？

意为“…… 有多高？”，be 动词要和主语一致。提问长度用how long, 提问年龄用how old。

如：

1) How tall is your sister? 你妹妹多高？

2) How long is the road? 这条路多长？

3) How old is your teacher? 你们老师多大？

2. I’m 1.6 metres tall. 我1.6米高。

表示身高、长度、高度、深度等度量结果时，可用“基数词 + 单位词 + 形容词”结构来表达。如：1) The classroom is about 10 meters long.

2) This tree is 5.5metres tall. 注意：

当表达的长度不足一米时，度量单位用单复数都可以。如：0.5米可以读成

zero point five metre 也可以读成zero point five metres.
