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。
"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。
