the hunting of these animals is the greatest threat to tigers.so the most important thing is to save the animals that tigers eat.问题是为什么the most important thing is后面用to save.换成saving行不行?求详解!
the most important thing is后面用to save.不能换成saving.因为to save.不定式表示【即将要做】的事.如果换成 is saving表示【正在进行】的动作.
再问： Be动词后能跟to吗？
再答： be后面可以跟不定式to。在此的to save the animals that tigers eat.不定式短语做表语。又如：My wish is to be a doctor.我的愿望是当一名医生。2.The students are to meet at the school gatetomorrow. 明天学生们将在学校大门口集会。
如果我帮到了你，请采纳，谢谢！
