Ladies and gentlemen:

Warmly welcome to our school. First of all, please permit me, on behalf of all the teachers and students in our school, to give you a warm welcome. Now let me give you a very brief introduction to our school.

There are 70 classes in three grades with more than 6000 students in our school. We have Chinese, maths, English, physics, chemistry, biology, politics, history, geography, P. E. and music. Besides, a computer course is also provided. There are three labs equipped with modern instruments and we have a computer room with over 50 advanced computers in it. The teachers love us students and we students respect our teachers. We listen attentively in class, learn from each other and help each other. After class we take an active part in sports or listen to music. We enjoy our rich and colorful school life.

That’s all. Thank you.

Step Three All the students will recite a passage.

China is large in area and rich in natural resources. The climate is different depending on the area. The south has cool, wet winters and hot, damp summers. This area is suitable for growing rice. The north has cold, dry winters and hot, rainy summers. Wheat is mainly grown in this area. The western part of China is dry with little rain all the year round. It is not good for growing crops, but some places produce a variety of fruit. And the eastern part of China enjoys plenty of rain most time of the year, so the crops grow very well.

Step Five 复习独立主格结构(absolute structure)的用法

导入：作状语的非谓语其逻辑主语不是句中主语时，需要给非谓语加上逻辑主语名词或代词(人称代词时用主格)，这种结构叫独立主格结构。例如：

The boy being unhappy, I gave him a candy. = As the boy was unhappy, I gave him a candy.

There being no buses, I had to walk home. = As there were no buses, I had to walk home.

It raining tomorrow, we’ll have to put off the sports meet.

= If it rains tomorrow, we’ll have to put off the sports meet.

I waiting for the bus, a stone hit me on the head.

= While I was waiting for the bus, a stone hit me on the head.

独立主格构成有两种形式：

一种是在名词或代词(人称代词时用主格形式)后直接加名词、形容词、副词、介词短语、现在分词、过去分词、不定式等；另一种是用with + 名词或代词(人称代词时用宾格) + 名词、形容词、副词、介词短语、现在分词、过去分词、不定式等。

一般来说表示“具有、携带着”等意思时，with加复合宾语结构较常用。例如：

It is so wet there that the trees are extremely tall, some measuring over 90 metres.那儿的湿度很大，所以树都长得特别高，一些高达90多米。（必修3第五单元）

The elderly man was telling a fairy tale(神话故事), with a lot of kids(小娃娃) listening
