专八Interview，由于原文对话过长，所以采取听写策略。一篇interwiew大概分为六个音频听写。
Hints:
dwindled
auxiliary
"highly evolved"
"decadent"
Neogrammarians
"low-level deviation"
"idealized form"
Sounds interesting. But this "decadence" argument has one major flaw. Even though the number of declensions and conjugations has dwindled, others parts of speech such as particles and auxiliary verbs have evolved to take their place. Anything that can be expressed in the ancient tongue can still be expressed today. Ultimately, this theory is highly subjective, as it relies on personal opinions, not scientific facts, of what is "highly evolved" and what is "decadent". So, strictly speaking, this comfort be called scientific explanation. Right. Is there any other theory? The next theory, proposed by the Neogrammarians, is one of natural process. They stated that changes are automatic and mechanical, and therefore cannot be observed or controlled by the speakers of the language. They found that what to a human ear a single "sound" is actually a collection of very similar sounds. They call it "low-level deviation" from an "idealized form". They argue that language change is simply a slow shift of the "idealized form" by small deviations.
