Question

一句话，帮忙分析下句子成分，谢！

I imagined he had trouble getting himself back together by the time I got back because he knew that I wouldn't laugh.

Answer 1

1 I imagined （主句-----主语，谓语）2 （that）he had trouble getting himself back together by the time I got back because he knew that I wouldn't laugh(宾语从句部分做宾语从句).3 he（主语） had （谓语）trouble （宾语） in getting back - - -(动名词结构做时间状语)4 by the time （时间状语连接词）I got back because he knew that I wouldn't laugh.5 because（因为状语从句的连接词） he knew that I wouldn't laugh6 he knew that（宾语从句的连接词） I wouldn't laugh

--------你太牛了，能够找出含有这么多“从句”的一个句子。牛啊indeed.

Answer 2

I（主）
imagined（谓）
he had trouble getting himself back together by the time I got back because he knew that I wouldn't laugh.（宾语从句）

he（宾语从句主语）
had trouble getting himself back together（宾语从句谓语：不好拆开了）
by the time I got back(宾语从句中的时间状语）
because he knew that I wouldn't laugh（宾语从句中的原因状语从句）.

that I wouldn't laugh（宾语从句中的原因状语从句中的宾语从句）

真的很复杂
我猜想到我回来的时候他很难让自己恢复，因为他知道我不会笑。

Answer 3

because引导原因状语从句，imagine后面是宾语从句 have touble/difficulty doing sth是固定搭配，by the time是宾语从句的时间状语。

Answer 4

我想象他有麻烦让自己起来等我回来,因为他知道我不会笑。
