3、运用简单句与复合句的相互转换理论。如：

The man who is standing there is a policeman.

What we should do next is unknown.→

What to do next is unknown.

We are thinking of how we can finish the work in time.→

We are thinking of how to finish the work in time.

4、综合运用同义词语与不同句式。如：“他做完练习后，便出去了”可译为：

(1) After he had finished the exercises, he went out.

(2) After he finished the exercises, he went out.

(3) Having finished the exercises, he went out.

(4) Finishing the exercises, he went out.

(5) After finishing the exercises, he went out.

(6) The exercises being finished, he went out.

(7) The exercises finished, he went out.

(8) The exercises having been done, he went out.

另外，还可采用修辞等方法，以增进多种表达的本领。
