A begin B begins
C having begun Dbeginning
为什么

According to the rule,once ,the research plan cannot be changed.A begin B beginsC having begun Dbeginning为什么
其实如果没有前面的According to the rule,最常见的说法可能是 once has begun,the research plan cannot be changed.(一旦实验被开始实施,实验计划变不能再被改变)这是最常见的说法,用begun其实是once (the research) has begun,或者(If a research) has once begun的简略说法,因为主语是research.
但是第一这个选项木有.第二According to the rule有点暗喻这是个常识性规定,所以偏向一般现在时.这样的话另一种可行的说法就是According to the rule,once (you) begin,the research plan cannot be changed.根据规定,一旦你开始了,实验计划便不能再被改变.这里的隐藏主语因为变了是“you”,加上一般现在时,所以begin也是可以的.
