④火起来时，我完全不知所措。

顺便说说神马叫定语从句，，不用太复杂，简略一点重要的。

Answer 1

定于从句特点是把整个定语从句从句子中拿出来也可以单独成一个完整的句子。定于从句修饰名词和代词。例如：He is the guy who will win the game. 这个句子who will win the game就是定于从句，修饰the guy。当然，the game也可以用定语从句修饰，这样就可以组成一个无限长的句子了。
翻译：

2. The snake sent the sparkles to the ground when it twined itself on the wire, which caused the fire. (which引导非限制性定语从句)
或者：The snake sent the sparkles that led to the fire to the ground when it twined itself on the wire. (that led to the fire 是定语从句)

语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般跟在它所修饰的先行词后面。(定语从句的概念:在复合句中,修饰某一名词或代词的从句叫做定语从句.被修饰的名词或代词叫做先行词,定语从句一般放在先行词的后面.
