求下面句子的成分分析,,,

1]What it was to become was uncertain until between 4.5and3.8billion years ago whenthe dust settled into a solid globe.

Answer 1

这句是主语从句。
What it was to become 主语 was 谓语
uncertain 形容词当表语

until between 4.5and3.8billion years ago 。until在这里是介词，between 4.5and3.8billion years ago 是介词宾语。这句是构成整句时间状语。

when the dust settled into a solid globe。是由when引导的定语从句，先行词是between 4.5and3.8billion years ago

例句；he came last night when i was out.

Answer 2

这是高中语法问题，分析如下~~~~

What it was to become 名词性从句 表示主语 注意：可以这样理解it was to become What其实后边的东西都是为没有明确指代意义的what服务的

was系动词 谓语

uncertain 表语

between 4.5and3.8billion years ago 状语 表示时间

when the dust settled into a solid globe 是when引导时间的同位语从句 修饰前边的那个时间的

Answer 3

what it was to become 主语 was 系词 uncertain until between 4.5and3.8billion years ago 表语 whenthe dust settled into a solid globe是between 4.5and3.8billion years ago 的定语
