多一连词
　　① 状语从句与主句之间多一并列连词，如：though… but; because… so; the more… and the more
　　② 充当状语的分词与主句之间多一并列连词。如：
　　Sitting down and he began to work.
　　Regarded as the best in the class, so he was praised at the meeting.
　　③ 从属连词后多一 that。如：because that… since that…, unless that…
　　④ 复合宾语前多一 that。如：
　　I heard that him say it.
　　I found that her lying on the ground.
　　Some people don’t like football, but many people who do like it.
　　⑤ 在“形容词 + 不定式”句型中，如果不定式的逻辑宾语或介词宾语就是句子的主语，再用代词作宾语或介词宾语则是多余的。如：
　　This question is too difficult to answer it.
　　The house is nice to live in it.
　　⑥ 在“连词 + 分词 / 名词 / 形容词 / 副词 / 介词词组”结构中，加上代词作主语是多余的。如：
　　He took notes while he reading.
　　If it heated, ice turns to water.
