　　● 题目：

　　When studying their mother tongue, linguists act as their own informants, judging the ambiguity, acceptability, or other properties of utterances against their own intuitions. (test3 passage 3)

　　● 分析：

　　本句的主句为“linguists act as their own informants”, “When studying their mother tongue”为when引导的现在分词短语做时间状语;“judging the ambiguity, acceptability, or other properties of utterances against their own intuitions.”为现在分词短语做伴随状语，引导词省略。
