本期重点：句子结构不完整
比较复杂的复合句最容易出现此类错误，因为句子较长，缺少了某个成分，如主语、谓语、宾语、连词等等。
考点例析：
例1： If his aim is inaccurate and he scores a goal, enjoys S3.____the hunter’s triumph of killing his prey.
解析：这是由一个条件状语从句引导的复合句。但主句只有谓语动词enjoys，缺少主语，因此要步上主语。根据从句的his aim可推断应该加上主语he。
例2：Nuclear physicists who interested in the structure of 5._________atoms cannot observe protons, electrons and neutrons directly.
解析：如果将who后面的部分作定语从句，那么它绝少谓语，故将who去掉，此时分词短语interested in直接作定语修饰前面的physicists。或在who后加are，补全定语从句。
例3：This alliance guarantees that all leprosy patients, even they S6.______are poor, have a right to the most modern treatment.
解析：even是副词，后面不能直接跟句子，根据句子的意思，应该在even后加if或though。
