翻译他昨天晚上没有参加聚会，真可惜。用主语从句

你好，可翻译为：It is really a pity/shame that he didn`t attend the party last night.
我们队赢了，这使我们很高兴。（定语从句）

Our team has won the game,which made us very pleased.
同位语：同位语从句属于名词性从句，大多由从属连词that引导，常常跟在fact, idea, opinion, news, hope, belief等名词后面。同位语从句一般用来解释或说明这些名词的具体含义或内容，在逻辑上表现为同位关系。例如：

They are familiar with the opinion that all matter consists of atoms.他们很熟悉这一观点，所有的物质都是由原子构成的。

1、从先行词来看

同位语从句与名词之间在逻辑上是"主语＋be＋表语"的关系。该名词是需要做特殊说明的抽象名词。例如：

They were delighted at the news that their team had won.当听到他们的球队赢了的消息时，他们欣喜若狂。

2、从引导词来看

引导词that在同位语从句中是连词，只起连接作用，无具体词义，that不可省略；that在定语从句中是关系代词，它在从句中充当一定成分---主语或宾语，有具体词意，作宾语时还可以省略。试比较：

The factory(that)we visited yesterday is a chemical one.我们昨天参观的那家工厂是化工厂。(that在从句中作宾语，所以此句是宾语从句)

The news that he will leave for Shanghai is true.他将要去上海的消息是真的。(that只起连接从句的作用，所以此句是同谓语从句)
满意请采纳，谢谢！

That he didn't attend the party last night is such a pity.（That 引导的主语从句，但不太符合英语“孔雀结构”，有头重脚轻的嫌疑）
It is a pity that he didn't attend the party last night.（It做形式主语，后边是that引导主语从句。一般都会这么说。）

请及时采纳回答。

He didn't show up at the party last night, it's a pity.

什么？说详细一点
