策略之一：用介词短语替代从句。例：
原句：While they were playing tennis, she started an argument that lasted all morning。
修改后：During tennis she started an argument that lasted all morning。
原句：When you come to the second traffic light, turn right。
修改后：At the second traffic light turn left。
策略之二：删除诸如"who is”或"that is"之类的关系代词，变从句为短语。例：
原句：The novel, which is written in three parts, told a story that took place in the Middle Ages。
修改后：The three-part novel told a story set in the Middle Ages。
注：把句中的"three parts"改用形容词来表达，节省了四个不必要的单词"which is written in"。我们经常可以将关系代词如"that"去掉，这只会引起最少的变动。
策略之三：剔除你不需要的单词。例：
Two joint partners will present their views over a long-distance telephone call。
写完这样的句子后，你自己再读一遍，挑出单词"joint"和"telephone"，注意删去不必要的词。
