介词，后面是可以加从句的。
例如：I am thinking of how to get there.They are talking about what to do next.I tried not to think of what he was doing.介词后面可以接 wh-word 从句，但不可接 that 陈述句称为“复合型连词”例如： as if, even though, as soon as 等）。所以：in that = becausebut that = unless/if notexcept that = unless/if not介词不能引导从句，但是介词短语可以作为副词性短语，比如on a day，注意它不是从句。副词性短语出现在句首，后加逗号，表明它是附加信息。最后，从句的模版是从句连接词➕主语➕动词。另外某些情况下，分词可以代替从句连接词➕主语，让整个句子紧凑不啰嗦
