，的用法？？

1.He told us to write a word to describe him, and when we had done so, he pasted the words on a poster. This must have been a revealing exercise for him because, upon the sight of such
descriptions as “bitter”and “sarcastic”, he was shocked。
===================================
1.he pasted the words on a poster这是什么意思？？
2.This must have been a revealing exercise for him because, upon the sight of such descriptions as “bitter”and “sarcastic”, he was shocked。这是什么意思？？
3.就是什么的句子，为什么because的前面没有逗号，逗号在后面？？？我觉得应该是逗号在前面
类似的用法我也见过。能帮我解释一下，再举个例子吗？谢谢
The lesson of learning from other’s opinions of yourself extends much farther than the song of a
fictional character. Two days ago, in an art class, my group of students had assigned self portraits due.Most of us brought in photographs of ourselves. Nevertheless, one boy brought nothing and handed us all slips of paper. He told us to write a word to describe him, and when we had done so, he pasted the words on a poster. This must have been a revealing exercise for him because, upon the sight of such descriptions as “bitter”and “sarcastic”, he was shocked. In the case of this boy, he had not realized how his personality appeared to others. Though he might not have thought himself “bitter”, his friend’s comments certainly made him seem that way. The fact that we need others in order to understand ourselves is clearly shown by this boy’s
revelation.
这是句子的出处

Answer 1

译文：
他让我们用一个字来对他进行描述，当我们完成以后，他将这些字粘贴到一张宣传画上。此举对他肯定是一次具有启迪作用的练习，因为当他看到诸如“刻薄”、“挖苦”等描述后，他大吃一惊。

1 he pasted the words on a poster他将这些字粘贴到一张宣传画上/海报上

2 .This must have been a revealing exercise for him because, upon the sight of such descriptions as “bitter”and “sarcastic”, he was shocked此举对他肯定是一次具有启迪作用的练习，因为当他看到诸如“刻薄”、“挖苦”等描述后，他大吃一惊

3 当because后面需要插入一个从句（如状语从句）时，它后面要跟一个逗号，以便插入从句，从句结束后也要用逗号，后面的句子与前面的because连接起来。
例句：
He came to school today because, upon the sight of the stern look of his father, he had no other choice.看到父亲严厉的眼光，他今天上学了，因为他别无选择。

Answer 2

1. 他把我们写的（文字）贴到了壁板上。 poster是“海报,宣传报”的意思，如校园里发布信息的白板；

2. 这对他一定是有所启发的，因为一看到诸如“刻薄”和“讽刺”的词眼，他都为之一震。

because这里就是个普通的连词，加逗号是表示停顿，这里应该是语义表达的需要而不是语法上的另类用法。

另一个例子；
He loves you because, ever since the first day he met you, he couldn't help thinking of you all the time.

Answer 3

1. 他把这些词贴在了海报上
2. 这也许对他来说是个揭示自我的过程，因为对于像“尖酸”、“刻薄”这样的描述，他还是很吃惊的。
3. 这里，upon the sight of such description as "bitter" and "sarcastic"其实是做了一个插入语，用逗号把这个插入语插进去，表示补足成分，把这部分遮掉，就是for him because he was shocked，这个because前加不加逗号均可。

例：She was a stupid girl because, as far as I am concerned, she could not even work out the average math problem.

Answer 4

1 他在海报上粘贴了这个消息
2 这一定是他暴露自己，一看到难以接受和讽刺的描述，他就感到震惊
3 because引导的句子在前，后面的句子用,
