(一)such a/an+形容词+名词+that…句型可与so+形容词+a/an+名词+that…句型互换。进行这种转换时其中的名词必须是单数可数名词，不定冠词的位置也必须发生变化。例如：

He is such a clever boy that I like him very much.=He is so clever a boy that I like him very much.他是如此聪明的一个男孩，我很喜欢他。

(二)such…that…句型可与so…that…句型互换。so后面应跟形容词，句意及逻辑关系也要作适当调整。例如：

This flower is so beautiful that I like it very much.=This is such a beautiful flower that I like it very much.这朵花非常美丽，我很喜欢。

These flowers are so beautiful that I like them very much.=T-hese are such beautiful flowers that I like them very much.这些花非常漂亮，我非常喜欢。

(三)so…that…句型可与so that句型互换。

在so…that…句型中，so后面跟的中心词可以是副词，也可以是形容词。句型转换时，应根据句意及逻辑关系将整个句子结构作相应调整。例如：

He spoke so fast that I couldn’t understand him.=He spoke ve-ry fast so that I couldn’t understand him.他讲得如此之快，以致于我听不懂他的话。

His speech at the meeting was so encouraging that we all res-pected him very much.=His speech at the meeting was very cnco-uraging so that we all respected him very much.他在会上的讲演非常鼓舞人心，我们都对他肃然起敬。
