“毫不惧怕”中的“不”该读第几声?是根据前面的第二声,还是后面的第四声变调,或是根据习惯变为轻声?笔者查阅了《现代汉语》(黄伯荣、廖旭东主编,高等教育出版社出版),书中对“不”的变调是这样规定的:1.“不”单念或用在词句末尾,声调不变,读原调:“不”念去声。例如:不、偏不。2.在去声前,一律变阳平。例如:不怕、不够、不看、不像。 “No ” in the “no fear ” in the first few sound? Is based on the second front, or behind the fourth tone, or according to the habit into softly? The author consulted the “modern Chinese ”(Huang Borong, Liao Xudong editor, Higher Education Press), the book on the“ no ”tone is regulated as follows: 1. “ No ”single read or used at the end of the sentence, the tone unchanged, read the original Tone: “no ” read the sound. For example: No, no. Before the sound, all become positive. For example: not afraid, not enough, do not look, unlike.
