《背影》中有这样一句话:“走到那边月台,须穿过铁道,须跳下去又爬上去。”有些同学认为:“爬上去”错了,应该是“爬上来。”也有些同学认为:没错,应该是“爬上去。”那么,究竟是“爬上来”,还是“爬上去”呢? 认为错了的同学提出:“下去”和“上来”是一对相反的趋向动词,既然前面是“(跳)下去,”后面就应该是“(爬)上来。” In Backing, there is such a saying: “When you get to the platform on that side, you have to cross the railway. You must jump and climb.” Some students think that “climb up” is wrong, and it should be “climb up.” Some The students think: Yes, it should be “climb.” So, what exactly is “climb up” or “climb up?” The student who thinks wrong suggests: “Going down” and “Up” are opposite directional verbs. Since the front is “(jumps),” the back should be “(climbing).”
