两个英语句子求详细分析

1.the fungus that ants cultivate was a single type that they had propageted,essentially unchanged from the distant past
这里的that后面是什么从句 主句是什么 句子成份求具体分析

2.when desert ants return from a foraging trip, they navigate by integrating bearings and distances, which they continuously update in their deads.
这里的which后面是什么从句 主句是什么 句子成份求具体分析
第一句
they指的是什么？为什么？ 能给我翻译一下这个句子吗

Answer 1

第一个句子，目测单词拼错了一个，应该是“unchanged”吧？
这个句子里有两个that，都是引导的定语从句。
主句是the fungus was a single type。that ants cultivate做的是fungus 的定语从句，而后面的that they had propageted,essentially unchanged from the distant past 做的是 type 的定语从句。

第二个句子，主句是they navigate by integrating bearings and distances，这里的they指的是前边的 desert ants。前边的when desert ants return from a foraging trip，是一个时间状语从句。 which 后面的句子同样是定语从句，做的是bearings and distances的定语。

祝进步。

Answer 3

1.the fungus that ants cultivate was a single type that they had propageted,essentially unchanged from the distant past
第一个that是定语从句做cultivate的宾语；第二个that是定语从句，做propageted的宾语成分。主句是.the fungus was a single type
.when desert ants return from a foraging trip, they navigate by integrating bearings and distances, which they continuously update in their deads.
which引导的是非限制性定语从句，主句是 they navigate by integrating bearings and distances，when desert ants return from a foraging trip是时间条件状语从句，
