It指代：it可以指代主语从句和不定式：it is important that we finishe on time. It is difficult to do this research.
It不能指代介词短语，DE中的介词短语是from the release / after the time
现在完成时：for, since, so far, ever, never, just, yet, till, untill, up to now, in past years…..
问题：分词短语在句首逻辑主语等于句子主语，这里的逻辑主语是什么意思？难道会有逻辑主语不等于句子主语的情况？
35 years前面是否不能加the？
