Elision, Assimilation Length of a Sound By Zeng Rong Elision Definition: The omission of a sound or sounds, either within the body of a word or at the junction of words. Warming up activity 热身练习 Read the following words and phrases. Do you think there are changes for the three words when they are put with other words? Why or why not? Definition of assimilation The process by which a sound is modified so that it becomes similar or identical to an adjacent or nearby sound. For example, the prefix in- becomes im- in impossible by assimilation to the labial p of possible. Application of assimilation Assimilation is applied so that it becomes similar or identical to an adjacent or nearby sound. Practice Reading the following sentences, paying attention to assimilation in each sentence. Nice to meet you. Would you do it? Don’t you think so? 1. Progressive Assimilation The assimilated sounds are influenced by the preceding sounds. ?It raining cats and dogs.? ?? ?? ?? ?He stopped reading and looked up. ? ?? ?? ?? ??? “On my way home, I looked up an old friend of mine.”? ?? ?? ?? ??? ?? ?? ?? ?? He pulled a tired smile when he stepped out of the room. 2. Regressive Assimilation: the sound is influenced by the following sound. 前面的音受后面的音影响，叫逆向型同化。 如news的单独读音是[nju:z]，但在复合词newspaper中却读[ `nju:speip?],[ nju:z]中的[z]在复合词[ `nju:speip?]中由于受后面清辅音[p]的影响而清化变成了[s]。又如：used to 短语本该读成[ ju:zd tu]，但受后面[t]的影响，浊辅音[d]变成了[t]，而[t]又影响[z]的读音，使其清化为[s]，所以现在应念成[ ju:s tu]。 Before I eat dinner, I read the newspaper for a while. We read the newspaper every morning. We used to go there every year. Our company used to do business with theirs.? 3. Reciprocal Assimilation: Two neigh-boring sounds influence each other and become a new sound. 相互同化 相互同化就是前后两个连在一起得音念起来不太方便，于是连在一起的两个音就互为影响而混合成一个新的、折衷的、比较好念的音，使之念起来顺口. /s/ + /j/ = /?/ God bless you.
