That what the manager said at the meeting isn't ture astonished all of us.
分析:这是一个主语从句的嵌套,即做主语的从句本身又是一个主语从句.
句子的主语是what the manager said at the meeting isn't ture,这是整句话的主语,是以句子的形式出现的,即句子充当主语;而 what the manager said at the meeting isn't ture这句话本身又是一个主语从句,what在这里是一个关系代词;
that是一个关联词无实意,引导主语从句;
谓语是astonish,宾语是all of us.
that what 并非连用.
